Description:
202204036 1 TITLE Method and apparatus for proactive mobile network-assisted incident management TECHNICAL FIELD The application generally relates to wireless communications and, more particularly, to a smart infrastructure system and a wireless communications system. BACKGROUND When user equipment (UE), i.e., a user equipment (UE) device, enters a cell of the of a communication network NW, such as LTE or 5G NR (New Radio), initial access to the network must be established. In this text, the 5G NR terminology will be used for describing the technology. However, the method and apparatus will apply to different cellular based wireless communication systems using RACH-mechanisms for connecting user equipment to the network, i.e., to the base station gNB of the network, including 5G NR, 4G (LTE) and even 3G (UMTS/WCDMA). Inter alia, initial and random access is established by a process between UE and gNB (network) for a UE to acquire uplink synchronization and obtain specified information for the radio access and communication. This process is performed via the so-called Random Access Channel (RACH). The typical contention-based RACH procedure contains the following 4 steps: The UE selects a random access preamble from a set of predefined preambles including a random sequence number for the preamble and transmits the preamble on the PRACH (Physical Random Access Channel), which corresponds to Msg1. The base station gNB responds (Msg2) providing a Time Advance (TA) command for timing adjustment, a temporary identifier (called RA-RNTI (Random Access Radio Network Temporary Identifier)), and an initial uplink grant for the UE. Using this initial Internal 202204036 2 uplink grant, a UE sends a further message (Msg3) on PUSCH (Physical Uplink Shared Channel) with a certain RRC (Radio Resource Control) message, such as RrcRequest. The base station gNB responds with a further message (Msg4) for contention resolution containing the UE identity. At this step, the network provides UE with a C-RNTI (Cell Radio Network Temporary Identifier). Alternatively, the typical contention free RACH procedure simplifies the over-the-air signaling, as the gNB pre-configured the UE to use a specific RACH preamble. In the first step, the UE sends RACH preamble and some data (incl. RA-RNTI, indication for L2/L3 message size), which is referred to as MsgA. In the second step, the gNB provides the Random Access Response (incl. TA, C-RNTI, UL grant for L2/L3 message), which is referred to as MsgB. The random access procedure is triggered by a number of events: - Initial access from RRC_IDLE state; - RRC Connection Re-establishment procedure; - DL or UL data arrival, during RRC_CONNECTED or during RRC_INACTIVE while Small Data Transmission (SDT) procedure is ongoing, when UL synchronisation status is “non-synchronised”; - UL data arrival, during RRC_CONNECTED or during RRC_INACTIVE while SDT procedure is ongoing, when there are no PUCCH resources for Scheduling Request (SR) available; - SR failure; - Request by RRC upon synchronous reconfiguration (e.g., handover); - RRC Connection Resume procedure from RRC_INACTIVE state; - To establish time alignment for a secondary Time Alignment Group (TAG); - Request for Other System Information (SI); - Beam failure recovery; - Consistent UL LBT failure on SpCell; - SDT in RRC_INACTIVE state; - Positioning purpose during RRC_CONNECTED requiring random access procedure, e.g., when timing advance is needed for UE positioning. Internal 202204036 3 RACH Occasion (RO) is an abstract 2D area specified in time and frequency domain that is available for the reception of the RACH preamble (PRACH) in the first step. In LTE, there is only one RACH occasion (RO) specified by RRC message (SIB2) for all the possible RACH preambles. In 5G NR, the Synchonization Signal Blocks (SSBs) are associated with different beams. A UE selects a certain beam based on received signal strength and sends RA preamble on PRACH corresponding to the selected beam. The selected beam may correspond toa certain location in the network cell, which is correlated with a specific SSB. 3GPP defines a mapping between SSB and RACH Occasion (RO). By detecting to which RO the UE sends the RACH preamble, the gNBcan determine which SSB beam was selected by the UE, and where it is located in the network cell. The mapping between SSB and RO is defined by the following two RRC parameters: ^ msg1-FDM, ^ ssb-perRACH-OccasionAndCB-PreamblesPerSSB. Parameter “msg1-FDM” specifies how many RACH Occasions (ROs) are allocated in frequency domain (at the same location in time domain). Parameter “ssb-perRACH- OccasionAndCB-PreamblesPerSSB” specifies how many SSBs can be mapped to one RO and how many preamble indices can be mapped to a single SSB. The higher these parameters are, the more congestion may occur for reception of the RACH preamble. The overall mapping logic is described in 3GPP TS 38.213 – 8.1 and listed below: ^ First, in increasing order of preamble indexes within a single PRACH occasion. ^ Second, in increasing order of frequency resource indexes for frequency multiplexed PRACH occasions. ^ Third, in increasing order of time resource indexes for time multiplexed PRACH (RACH Preamble) occasions within a PRACH slot. ^ Fourth, in increasing order of indexes for PRACH slots. As per 3GPP TS 38.331 (v17.1.0, Sec.5.2.1) the SIB1 is transmitted on the DL-SCH with a periodicity of 160 ms and variable transmission repetition periodicity within 160 Internal 202204036 4 ms as specified in 3GPP TS 38.213 [13], clause 13. The default transmission repetition periodicity of SIB1 is 20 ms but the actual transmission repetition periodicity is up to network implementation. For SSB and CORESET multiplexing pattern 1, SIB1 repetition transmission period is 20 ms. For SSB and CORESET multiplexing pattern 2/3, SIB1 transmission repetition period is the same as the SSB period (3GPP TS 38.213 [13], clause 13). SIB1 includes information regarding the availability and scheduling (e.g., mapping of SIBs to SI message, periodicity, SI window size) of other SIBs with an indication whether one or more SIBs are only provided on-demand and, in that case, the configuration needed by the UE to perform the SI request. SIB1 is cell-specific SIB. This is visualized in Fig.1 showing RACH Occasions for different settings of the RRC parameters. In Fig. 1a, parameter “msg1-FDM = 1” specifies that one frequency is used in the frequency domain, and parameter “ssb-perRACH-OccasionAndCB- PreamblesPerSSB = 1” specifies that 1 slot in the frequency-time-domain is used for 1 SSB (sync signal) directed to one beam (of together 64 beams), each beam being related to a certain cell area or direction. This means that only one PRACH can be sent by one UE in one location (SSB X, X=0, …, 63) of the cell. In case of many UEs in one location there is congestion in the RACH (Random Access Channel). In Fig.1b, parameter “msg1-FDM = 2” specifies that two frequencies are used in the frequency domain at one time, and parameter “ssb-perRACH-OccasionAndCB- PreamblesPerSSB = 8” specifies that 1 slot in the frequency-time-domain is used for 8 SSBs (sync signals) directed to eight beams (of together 64 beams), i.e., UEs in eight (e.g., neighbored) areas share one RO in time and frequency domain. However, the repetition rate for PRACH is faster that in Fig.1a. In Fig. 1c, parameter “msg1-FDM = 2” specifies that two frequencies are used in the frequency domain at one time, and parameter “ssb-perRACH-OccasionAndCB- PreamblesPerSSB = 1” specifies that 1 slot in the frequency-time-domain is used for 1 SSB (sync signal) directed to one beam (of together 64 beams), each beam being Internal 202204036 5 related to a certain cell area or direction. This halves the repetition rate in comparison to Fig. 1a, but extends the repetition rate in comparison to Fig. 1b by a factor of 8 (allowing, however, to send a PRACH for one UE in each beam direction. In Fig.1d, parameter “msg1-FDM = 2” specifies that two frequencies are used in the frequency domain at one time, and parameter “ssb-perRACH-OccasionAndCB- PreamblesPerSSB = 0.5” specifies that 1 slot in the frequency-time-domain is used for 1 SSB (sync signal) directed to one beam (of together 64 beams), each beam being related to a certain cell area or direction. This means, that 2 UEs using the same beam (being related in the same cell area or direction) can send a PRACH simultaneously. This doubles the repetition rate in comparison to Fig.1c. The handling of the RACH Occasions (ROs), as described before, leads to the following problems, in particular in automotive applications, if critical situations are predicted. If many UEs (such as vehicles, but also mobile phones or other network communication devices of participants in a traffic situation, such as pedestrians or cyclists) are present in one area of a cell of the network, and critical situations are predicted in this specific geographical area, a significant number of concurrent and urgent communications could be required (e.g., V2X warning messages via Uu interface), but not possible due to congestion. Such congestion may result in critical communication delays. Further, automotive radar users may face significant mutual interference, resulting in degraded radar performance. Both problems lead to an ineffective use of the wireless communication network. SUMMARY It is an object of the invention to provide more effective use of user equipments connected to the wireless communication network. Internal 202204036 6 This invention gives a solution for this described problem accordingly. The disclosed concept addresses at least one of the two unsolved combined problems of congestion in mobile communications and interference among automotive radars. The problem is in particular solved by the method for proactive mobile network- assisted incident management by a smart infrastructure device connected to a wireless communication network according to claim 1, wherein the smart infrastructure device detects objects in or around a geographical area, predicts critical events in said geographical area and sends the one or more predicted critical events (PCE) to the wireless communication network. The wireless communication network, in particular a base station of the wireless network, explicitly indicates which resources of the wireless communication network are to be used by a user equipment (UE). This enables the network to proactively provide or activate resources of the network for several types of functions in a given geographical area and in a UE-identity independent manner. This may include wireless communications, such as better RACH resources for initial and/or random access to the network by multiple (more than one) user equipments simultaneously (or within a very short time period) and/or sensing, such as using radio resources for automotive radar sensors. The benefits are faster network access (by providing better RACH resources) avoiding potential congestions and/or providing reduced interference during sensing with radar sensing using parts of the wireless communication spectrum. This is evident from the advantageous embodiments of the proposal as explained below. According to one embodiment, explicitly indicating may comprise to assign additional and/or prioritized random access channel occasions for use by user equipments in said geographical area for initial and /or random access to the wireless communication network. The more RACH occasions are available, the more user equipment devices can randomly access the wireless communication network. It is utmost effective of offer this possibility in case of predicted critical events and related to such geographical areas where the critical events are predicted to possibly occur. This is in contrast to the RACH occasions in the frequency-time-domain distributed Internal 202204036 7 equally over the entire geographical area of the communication cell and leads to effective use of the resources. In a specific proposal said additional and/or prioritized random access channel occasions may be pre-configured and indicated to the user equipment devices by the base station of the wireless communication network, e.g., in a broadcast transmission reaching all user equipment devices that may potentially request initial and/or random access to the wireless communication network. The broadcast transmission may be limited to said geographical area(s), for which (one or more) critical events are predicted. Further, the base station may indicate which random access channel occasions are to be used by default and which ones are to be used for special, predicted critical events. The base station and/or network can determine and regularly update the configuration of random access channel occasions, e.g., based on historical event data, or when triggered by a predicted critical event. Accordingly, normal default access may be chosen for any unspecific access to communication network, e.g., for ordinary status reports. In case of critical events, such as an impending accident or high traffic density in front of a dangerous intersection, RACH occasions reserved for critical events can be used guaranteeing faster and prioritized network access. In an advantageous embodiment, the base station or, more generally, the wireless communication network will activate and/or communicate said additional and/or prioritized random access channel occasions on the fly, if a predicted critical event is received by the wireless communication network. On the fly means that receipt of a predicted critical event causes the base station or network to immediately reserve the additional RACH occasions in the frequency-time-domain of the communication network and/or communicate the activation / existence of the additional RACH occasions in a provided urgent communication process. Predicting critical events may be realized in a user equipment device, in a base station of the wireless communication network and/or another wireless communication network device, such as a smart infrastructure device (SID) equipped Internal 202204036 8 with one or multiple object detecting sensors and a data processing unit, wherein the data processing unit may be adapted to perform an Artificial Intelligence (AI) algorithm for detecting, classifying, and/or tracking objects in or around a geographical area, such as an intersection. According, in line with the proposal, predicting of critical events may be done in any device that may be communicatively coupled to the wireless communication network. In a specific embodiment of the proposal it may be provided that, if at least one (or preferably if at least two) user equipment(s) connected to a wireless communication network is a (or are) radar user equipment (UERs), the base station indicates to said radar user equipment (s) which radio resources and/or channels of the wireless communication network (NW) may be used for radar purposes. This may in particular be useful for specific radar technology, such as FMCW (Frequency Modulated Continuous-Wave) for radar sensing and/or OFDM (Orthogonal Frequency Division Multiplexing) for radar sensing and communications, in combination with a 5G NR wireless communication network, both (radar sensing and communications) working, e.g., with millimeter wave (mmWave), FR2, THz or future wireless communication bands. In case of possible interference of radar systems in different vehicles (as a predicted critical event), some of the radar sensing and/or communication entities may switch to different communication bands to avoid interference. In case of more than two possibly interfering radar systems, the base station of the communication network may manage different frequency bands for use with the different radar systems to guarantee interference free radar sensing. It is a major advantage of this solution that the increase of bandwidth is achieved by using frequencies that are usually used by the communication system so that these frequencies are flexibly reserved for use by other (non-telecommunication) appliances. According to an advantageous proposal the base station reserves part of the radio spectrum originally assigned for wireless communication for radar usage, such as channels used for uplink or sidelink communications. In particular, part of the radio spectrum may be flexibly reserved for radar sensing purposes based on information or predicted critical events that are provided by a smart infrastructure device (SID). Internal 202204036 9 In a preferred proposal, the base station may indicate the radio resources and/or channels to be usable for radar purposes to said radar user equipment (UERs) via system information blocks (SIBs) or user equipment specific signaling or paging, as defined in the wireless communication network.

The description of elements in each figure may refer to elements of proceeding figures. Like numbers refer to like elements in all figures, including alternate embodiments of like elements. The detailed description set forth below, with reference to annexed drawings, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. Although terminology from 3GPP 5G NR may be used in this disclosure to exemplify embodiments herein, this should not be seen as limiting the scope of the invention. Fig.1a to 1d show schematically examples of the frequency-time-domain of RACH occasions RO according to the 3GPP 5G NR implementation, as already explained before. In comparison to these figures, Fig.6a to 6d show the frequency-time-domain of RACH occasions RO according to an embodiment of the invention. The RCC- Internal 202204036 18 parameters “msg1-FDM” and “ssb-perRACH-OccasionAndCB-PreamblesPerSSB” according to the 3GPP 5G NR implementation correspond identically to those described with respect to Figs. 1a to 1d, respectively. Thus, there are provided according to the 3GPP 5G NR implementation 64 RACH occasions in Fig. 6a, 7 RACH occasions in Fig. 6b, 64 RACH occasions in Fig. 6c, and 128 RACH occasions in Fig.6d, identically to Fig.1. However, for the beam correlated to the sync signal SSB #0 (and the related geometrical area of the cell), the base station gNB of the communication network has received a message from a smart infrastructure device (SID) indicating critical events in the geographical area of the communication network cell related to the sync signal SSB #0. Accordingly, the base station gNB has activated new resources of the wireless communication network (NW) to be used by user equipment devices (UE), these resources being in the example of Fig. 6a three additional RACH occasions RO#0, RO#1, RO#2, all in the geographical area related to sync signal SSB#0 (as indicated in Fig. 5. These may be used as prioritized random access occasions for urgent access of user equipment devices of participating members such as cars, motorcycle, bus and/or smartphone carried by pedestrians have installed a suited application to participate in the proactive mobile network-assisted incident management. In the examples of Figs. 6b, 6c and 6d, four additional RACH occasions RO#0, RO#1, RO#2, RO32 in the geographical area related to sync signal SSB#0, which max have been pre-configured by the base station gNB, are activated and communicated. Two of the additional RACH occasions RO#0, RO#1 may be labeled or used for prioritized random access, the additional RACH occasion RO#2 may be used for an ordinary additional access (to avoid congestion due to many potential user equipment devices UE requesting access, and the additional RACH occasion RO#3 may be assigned to radar systems for sensing to avoid interference of radar sensor signals. The wireless communication network may be an LTE network or some other wireless network, such as LTE, 5G or 5G NR (New Radio) network. The wireless network may include one or more base stations. The base station may be referred as BS, NB, Internal 202204036 19 eNodeB (or eNB), gNodeB (or gNB), an access point or the like, depending on the wireless standard implemented. A base station provides radio communication coverage for a particular geographic area called “cell”. In this text, base stations are denoted as gNB. User equipment (UE) may be referred as a mobile station, a wireless terminal, or the like. In some examples, user equipment may be a cellular phone, a wireless modem, a wireless communication device, a handheld device, a laptop computer or the like. User equipment may also be an IoT (internet of things) device, like wireless camera, a smart sensor or smart meter, a vehicle, a global positioning system device, or any other device configured to communicate through a wireless network. User equipment may support various communication modes, such as a connected mode (RRC Connected), an inactive mode (RRC Inactive), or an idle mode (RRC Idle) as defined by 3GPP. When operating in RRC Connected mode, user equipment is active and communicate with base station. User equipment may transition from communication mode to another using various commands and messages received from the base station. For example, user equipment may switch from RRC Connected state to RRC Inactive state upon receiving a RRC Release message including suspendConfig parameter. User equipment may enter RRC Inactive state without completely releasing radio resources when there is no traffic, in order to quickly switch back to RRC Connected states when necessary. In this case, user equipment and base station may store a context for the user equipment, for example an access stratum (AS) context, in order to apply said stored context when transitioning from RRC Inactive to RRC Connected state and thus reduce latency and signaling overhead. Such context may include Radio configuration parameters, such as uplink grant, RNTI (Radio Network Temporary Identifier), MCS and/or the like. Fig.2 shows schematically interference among automotive radars according to one exemplary situation, where two cars approaching each other are equipped with driver assistance systems (ADAS), in this case radar systems RS1, RS2 with interfering Internal 202204036 20 main radar beams MRB1, MRB2. Perception of car surroundings is key for advanced driver assistance systems (ADAS) and automated driving. Sensing systems include radar, lidar, camera, and ultrasound sensors. Automotive radar systems create mutual interference which may lead to misinterpretation of the resulting signals and degrade performance. Fig.3 shows schematically a similar situation with two cars B, A each having a radar system RS1, RS2, respectively. Each radar system RS1, RS2 has a main radar beam MRB1, MRB2 and radar side lobes RSL1, RSL2. Main radar beam MRB2 captures another car. This results in scattering SCT2 from the main radar beam MRB2. As both cars B, A are approaching the same intersection, main radar beams MRB1 and MRB2 cross each other at the intersection which may lead to interference. Accordingly, interference among automotive radars is a problem. In this embodiment of the invention, each of the radar systems RS1, RS2 is part of a radar user equipment (UER) communicatively coupled to a wireless communication system not shown in Fig. 2 and 3. The base station gNB recognizes the interference of the radar systems RS1, RS2 and indicates to one radar user equipment (UER), which radio resources and/or channels of the wireless communication network may be used for radar purposes. In this embodiment, radio resources of the communication network are assigned for radar use. Radar systems RS1, RS2 are vendor-specific, but applicable radio spectrum is defined in a harmonized manner, typically in mmWAVE bands. Using smart infrastructure, system radar users UER in certain geographical area (e.g., SSB#x) are detected. The base station gNB determines and indicates to radar users UER (via SIB or UE-specific paging or signaling) which radio resources/channel to be used, e.g., for specific radar technology (e.g., FMCW, OFDM) in certain geographical area (e.g., SSB#x). More specifically, the base station (gNB) determines to use part of the radio spectrum originally assigned for wireless communications (e.g., uplink, sidelink) for radar usage instead. Internal 202204036 21 Fig.4 shows a smart infrastructure device (SID) equipped with object detection sensors and data processing unit, e.g., a Multi-access Edge Computing (MEC) entity. An embedded AI algorithm will detect, classify, and track objects in or around the smart infrastructure device (SID), in the example shown an intersection. The smart infrastructure device (SID) predicts critical events (PCE) in said geographical area and sends said one or more predicted critical events (PCE) to the wireless communication network (NW), i.e., typically to the base station (gNB) of the network (NW). In the example shown, the smart infrastructure device (SID) recognizes, on the right- hand side of the figure, a road with a high volume of traffic and a large number of different road users, such as cars, bus, motor cyclist and pedestrians, all of which may be equipped with an user equipment (UE). This critical situation is sent to the base station gNB as predicted critical event (PCE). Fig. 5 shows scenario of Fig. 4 with the reaction of the base station gNB to the predicted critical events (PCE) sent by the smart infrastructure device (SID) to the network (NW), i.e., after the smart infrastructure device (SID) has provided the network NW with the predictions (PCE). The network NW (or more specifically, the base station gNB) assigns prioritized or more random access channel occasions (RO#0, RO#1, RO#2, RO#3) to geographical area identified by SSB#0, where critical events (PCE) are predicted. These additional random channel access occasions are shown In Fig.6d, in addition to the normal random access channel occasions (RO#4, RO#5) provided according to a standard 3GGP 5G NR implementation. In this embodiment more ROs for SSB #0 are assigned by the network to provide more possibilities for faster access of user equipment (UE), in order to receive critical alerts faster as provided by a standard implementation. The base station (gNB) / network (NW) explicitly indicates to the user equipment (UE) which resources to be used for random access (PRACH). For example, at initial or random network access of the user equipment (UE), random access occasions (ROs) are pre-configured by the base station (gNB) / network (NW). Here, the base station (gNB) / network (NW) indicates which ROs are to be used by default and which ones for special events. Internal 202204036 22 When triggered by a prediction event, the base station (gNB) will activate on the fly the ROs for special events. The apparatus comprises a processor and a memory, for example a Random Access Memory (RAM). The processor may be controlled by a computer program stored in the memory comprising instructions configured to implement a method for receiving Small Data Transmission (SDT) from a base station in a wireless communication network. More precisely, the computer program comprises instructions for receiving a paging notification from a base station while in inactive state, the paging notification comprising at least an indication that downlink small data is available for transmission, and a priority flag associated with said downlink small data, to determine at least a Synchronization Signal Reference Signal Received Power, and to postpone downlink data reception until next paging cycle when said priority flag indicates low priority downlink data and said at least a Synchronization Signal Reference Signal Received Power is below a threshold. On initialization, instructions of the computer program may be loaded into the memory before being executed by the processor. The processor implements the steps of the method according to the instructions of the computer program. The apparatus comprises a wireless communication unit, for example a 3G, 4G, 5G, 5G NR, WiFi or WiMax transceiver for exchanging messages with other apparatus. In particular, communication unit is configured by program instructions to receive a paging notification broadcasted by a base station and check if the received paging is addressed to the apparatus by comparing an identifier comprised in said paging notification with an identifier associated with the apparatus. The communication unit may be further configured to obtain an indication from said paging notification, regarding a priority associated with available small data. This indication may be a binary flag included in a PagingUE-Identity data field of the paging notification wherein the flag is set to indicates high priority small data. All cited approaches of the embodiments can be combined together with all the others disclosed accordingly. Internal 202204036 23 This feature is most beneficial for sensors, IoT devices, and even messaging and presence applications in smartphones. Internal
