Table 1: Example test cases for Pre-MG core requirements
Embodiment 1 :
However, in order to reduce the number of test cases as possible, if the testing procedure relatese to three successive time periods being included, both the requirements of Pre-MG activation/deactivation and intra-frequency measurement with gap can be tested together.
The testing procedure for the enhanced measurement gap may be based on the test procedure for the legacy measurement gap in the third generation partnership project (3 GPP) release-16 (Rell6, Rel-16, Rel 16, etc.) specifications. One difference between the legacy procedure and embodiments herein may be that the pre-MG activation/deactivation in the testing procedure may be needed herein.
The test cases for Pre-MG activation/deactivation delay and measurement reporting may be combined, for example as shown in the testing procedure in Figure 1.
The testing procedure for measurements with activated Pre-MG may include three successive time periods, with time durations of Tl, T2 and T3 respectively. During the duration of T 1 , the UE may be configured with Pre-MG, but the Pre-MG may be deactivated.
At the start of time duration T2, the serving base station (e.g., a gNodeB or gNB) may trigger Pre-MG activation. The UE may be expected to complete the Pre-MG activation within T2. At the start of time duration T3, the UE may not have timing information of neighbor cell(s) to be measured (e.g. cell 2).
Embodiment 2:
As illustrated in Figure 1, the testing procedure for measurements with activated Pre-MG may include three successive time periods, with time durations of Tl, T2 and T3 respectively.
During the duration of Tl, the UE may be configured with Pre-MG, but the Pre-MG may be deactivated.
At the start of time duration T2, the serving base station may trigger Pre-MG activation. The UE may be expected to complete the Pre-MG activation within T2.
At the start of time duration T3, the UE may not have timing information of neighbor cell(s) to be measured (e.g. cell 2).
The testing procedure for measurements with a deactivated Pre-MG may include two successive time periods, with time durations of Tl and T2, respectively, as shown in Figure 2.
During the duration of Tl, th UE may be configured with Pre-MG, but the pre-MG may be deactivated.
At the start of time duration T2, the UE may not have timing information of neighbor cell(s) to be measured (e.g. cell 2).
SYSTEMS AND IMPLEMENTATIONS
Figures 3-6 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments.
Figure 3 illustrates a network 300 in accordance with various embodiments. The network 300 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G/NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3 GPP systems, or the like.
The network 300 may include a UE 302, which may include any mobile or non-mobile computing device designed to communicate with a RAN 304 via an over-the-air connection. The UE 302 may be communicatively coupled with the RAN 304 by a Uu interface. The UE 302 may be, but is not limited to, a smartphone, tablet computer, wearable computer device, desktop computer, laptop computer, in-vehicle infotainment, in-car entertainment device, instrument cluster, head-up display device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electron! c/engine control unit, electronic/engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, M2M or D2D device, loT device, etc.
In some embodiments, the network 300 may include a plurality of UEs coupled directly with one another via a sidelink interface. The UEs may be M2M/D2D devices that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc.
In some embodiments, the UE 302 may additionally communicate with an AP 306 via an over-the-air connection. The AP 306 may manage a WLAN connection, which may serve to offload some/all network traffic from the RAN 304. The connection between the UE 302 and the AP 306 may be consistent with any IEEE 802.11 protocol, wherein the AP 306 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 302, RAN 304, and AP 306 may utilize cellular-WLAN aggregation (for example, LWA/LWIP). Cellular-WLAN aggregation may involve the UE 302 being configured by the RAN 304 to utilize both cellular radio resources and WLAN resources.
The RAN 304 may include one or more access nodes, for example, AN 308. AN 308 may terminate air-interface protocols for the UE 302 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and LI protocols. In this manner, the AN 308 may enable data/voice connectivity between CN 320 and the UE 302. In some embodiments, the AN 308 may be implemented in a discrete device or as one or more software entities running on server computers as part of, for example, a virtual network, which may be referred to as a CRAN or virtual baseband unit pool. The AN 308 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 308 may be a macrocell base station or a low power base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells.
In embodiments in which the RAN 304 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 304 is an LTE RAN) or an Xn interface (if the RAN 304 is a 5G RAN). The X2/Xn interfaces, which may be separated into control/user plane interfaces in some embodiments, may allow the ANs to communicate information related to handovers, data/context transfers, mobility, load management, interference coordination, etc.
The ANs of the RAN 304 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 302 with an air interface for network access. The UE 302 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 304. For example, the UE 302 and RAN 304 may use carrier aggregation to allow the UE 302 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN may be a master node that provides an MCG and a second AN may be secondary node that provides an SCG. The first/second ANs may be any combination of eNB, gNB, ng-eNB, etc.
The RAN 304 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and/or feLAA mechanisms based on CA technology with PCells/Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium/carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol.
In V2X scenarios the UE 302 or AN 308 may be or act as a RSU, which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an “eNB-type RSU”; a gNB may be referred to as a “gNB-type RSU”; and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs. The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications/software to sense and control ongoing vehicular and pedestrian traffic. The RSU may provide very low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may provide other cellular/WLAN communications services. The components of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller or a backhaul network.
In some embodiments, the RAN 304 may be an LTE RAN 310 with eNBs, for example, eNB 312. The LTE RAN 310 may provide an LTE air interface with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on CSI-RS for CSI acquisition and beam management; PDSCH/PDCCH DMRS for PDSCH/PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation/detection at the UE. The LTE air interface may operating on sub-6 GHz bands.
In some embodiments, the RAN 304 may be an NG-RAN 314 with gNBs, for example, gNB 316, or ng-eNBs, for example, ng-eNB 318. The gNB 316 may connect with 5G-enabled UEs using a 5G NR interface. The gNB 316 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 318 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 316 and the ng-eNB 318 may connect with each other over an Xn interface.
In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 314 and a UPF 348 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN314 and an AMF 344 (e.g., N2 interface).
The NG-RAN 314 may provide a 5G-NR air interface with the following characteristics: variable SCS; CP-OFDM for DL, CP-OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSI-RS, PDSCH/PDCCH DMRS similar to the LTE air interface. The 5G-NR air interface may not use a CRS, but may use PBCH DMRS for PBCH demodulation; PTRS for phase tracking for PDSCH; and tracking reference signal for time tracking. The 5G-NR air interface may operating on FR1 bands that include sub-6 GHz bands or FR2 bands that include bands from 24.25 GHz to 52.6 GHz. The 5G-NR air interface may include an SSB that is an area of a downlink resource grid that includes PSS/SSS/PBCH.
In some embodiments, the 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 302 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 302, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 302 with different amount of frequency resources (for example, PRBs) to support data transmission under different traffic loading scenarios. A BWP containing a smaller number of PRBs can be used for data transmission with small traffic load while allowing power saving at the UE 302 and in some cases at the gNB 316. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.
The RAN 304 is communicatively coupled to CN 320 that includes network elements to provide various functions to support data and telecommunications services to customers/subscribers (for example, users of UE 302). The components of the CN 320 may be implemented in one physical node or separate physical nodes. In some embodiments, NFV may be utilized to virtualize any or all of the functions provided by the network elements of the CN 320 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 320 may be referred to as a network slice, and a logical instantiation of a portion of the CN 320 may be referred to as a network sub-slice.
In some embodiments, the CN 320 may be an LTE CN 322, which may also be referred to as an EPC. The LTE CN 322 may include MME 324, SGW 326, SGSN 328, HSS 330, PGW 332, and PCRF 334 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the LTE CN 322 may be briefly introduced as follows.
The MME 324 may implement mobility management functions to track a current location of the UE 302 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc.
The SGW 326 may terminate an SI interface toward the RAN and route data packets between the RAN and the LTE CN 322. The SGW 326 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.
The SGSN 328 may track a location of the UE 302 and perform security functions and access control. In addition, the SGSN 328 may perform inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 324; MME selection for handovers; etc. The S3 reference point between the MME 324 and the SGSN 328 may enable user and bearer information exchange for inter-3 GPP access network mobility in idle/active states.
The HSS 330 may include a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 330 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 330 and the MME 324 may enable transfer of subscription and authentication data for authenticating/authorizing user access to the LTE CN 320.
The PGW 332 may terminate an SGi interface toward a data network (DN) 336 that may include an application/content server 338. The PGW 332 may route data packets between the LTE CN 322 and the data network 336. The PGW 332 may be coupled with the SGW 326 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 332 may further include a node for policy enforcement and charging data collection (for example, PCEF). Additionally, the SGi reference point between the PGW 332 and the data network 3 36 may be an operator external public, a private PDN, or an intra-operator packet data network, for example, for provision of IMS services. The PGW 332 may be coupled with a PCRF 334 via a Gx reference point.
The PCRF 334 is the policy and charging control element of the LTE CN 322. The PCRF 334 may be communicatively coupled to the app/content server 338 to determine appropriate QoS and charging parameters for service flows. The PCRF 332 may provision associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI.
In some embodiments, the CN 320 may be a 5GC 340. The 5GC 340 may include an AUSF 342, AMF 344, SMF 346, UPF 348, NSSF 350, NEF 352, NRF 354, PCF 356, UDM 358, and AF 360 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the 5GC 340 may be briefly introduced as follows.
The AUSF 342 may store data for authentication of UE 302 and handle authentication- related functionality. The AUSF 342 may facilitate a common authentication framework for various access types. In addition to communicating with other elements of the 5GC 340 over reference points as shown, the AUSF 342 may exhibit an Nausf service-based interface.
The AMF 344 may allow other functions of the 5GC 340 to communicate with the UE 302 and the RAN 304 and to subscribe to notifications about mobility events with respect to the UE 302. The AMF 344 may be responsible for registration management (for example, for registering UE 302), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 344 may provide transport for SM messages between the UE 302 and the SMF 346, and act as a transparent proxy for routing SM messages. AMF 344 may also provide transport for SMS messages between UE 302 and an SMSF. AMF 344 may interact with the AUSF 342 and the UE 302 to perform various security anchor and context management functions. Furthermore, AMF 344 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the RAN 304 and the AMF 344; and the AMF 344 may be a termination point of NAS (Nl) signaling, and perform NAS ciphering and integrity protection. AMF 344 may also support NAS signaling with the UE 302 over an N3 IWF interface.
The SMF 346 may be responsible for SM (for example, session establishment, tunnel management between UPF 348 and AN 308); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 348 to route traffic to proper destination; termination of interfaces toward policy control functions; controlling part of policy enforcement, charging, and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification; initiating AN specific SM information, sent via AMF 344 over N2 to AN 308; and determining SSC mode of a session. SM may refer to management of a PDU session, and a PDU session or “session” may refer to a PDU connectivity service that provides or enables the exchange of PDUs between the UE 302 and the data network 336.
The UPF 348 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 336, and a branching point to support multi-homed PDU session. The UPF 348 may also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), perform uplink traffic verification (e.g., SDF- to-QoS flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 348 may include an uplink classifier to support routing traffic flows to a data network.
The NSSF 350 may select a set of network slice instances serving the UE 302. The NSSF 350 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 350 may also determine the AMF set to be used to serve the UE 302, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 354. The selection of a set of network slice instances for the UE 302 may be triggered by the AMF 344 with which the UE 302 is registered by interacting with the NSSF 350, which may lead to a change of AMF. The NSSF 350 may interact with the AMF 344 via an N22 reference point; and may communicate with another NSSF in a visited network via an N31 reference point (not shown). Additionally, the NSSF 350 may exhibit an Nnssf service-based interface.
The NEF 352 may securely expose services and capabilities provided by 3 GPP network functions for third party, internal exposure/re-exposure, AFs (e.g., AF 360), edge computing or fog computing systems, etc. In such embodiments, the NEF 352 may authenticate, authorize, or throttle the AFs. NEF 352 may also translate information exchanged with the AF 360 and information exchanged with internal network functions. For example, the NEF 352 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 352 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 352 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 352 to other NFs and AFs, or used for other purposes such as analytics. Additionally, the NEF 352 may exhibit an Nnef service-based interface.
The NRF 354 may support service discovery functions, receive NF discovery requests from NF instances, and provide the information of the discovered NF instances to the NF instances. NRF 354 also maintains information of available NF instances and their supported services. As used herein, the terms “instantiate,” “instantiation,” and the like may refer to the creation of an instance, and an “instance” may refer to a concrete occurrence of an object, which may occur, for example, during execution of program code.

Additionally, the AF 360 may exhibit an Naf service-based interface.
The data network 336 may represent various network operator services, Internet access, or third party services that may be provided by one or more servers including, for example, application/content server 338.

The term “machine learning” or “ML” refers to the use of computer systems implementing algorithms and/or statistical models to perform specific task(s) without using explicit instructions, but instead relying on patterns and inferences. ML algorithms build or estimate mathematical model(s) (referred to as “ML models” or the like) based on sample data (referred to as “training data,” “model training information,” or the like) in order to make predictions or decisions without being explicitly programmed to perform such tasks. Generally, an ML algorithm is a computer program that learns from experience with respect to some task and some performance measure, and an ML model may be any object or data structure created after an ML algorithm is trained with one or more training datasets. After training, an ML model may be used to make predictions on new datasets. Although the term “ML algorithm” refers to different concepts than the term “ML model,” these terms as discussed herein may be used interchangeably for the purposes of the present disclosure.
The term “machine learning model,” “ML model,” or the like may also refer to ML methods and concepts used by an ML-assisted solution. An “ML-assisted solution” is a solution that addresses a specific use case using ML algorithms during operation. ML models include supervised learning (e.g., linear regression, k-nearest neighbor (KNN), descision tree algorithms, support machine vectors, Bayesian algorithm, ensemble algorithms, etc.) unsupervised learning (e.g., K-means clustering, principle component analysis (PCA), etc.), reinforcement learning (e.g., Q-leaming, multi-armed bandit learning, deep RL, etc.), neural networks, and the like. Depending on the implementation a specific ML model could have many sub-models as components and the ML model may train all sub-models together. Separately trained ML models can also be chained together in an ML pipeline during inference. An “ML pipeline” is a set of functionalities, functions, or functional entities specific for an ML-assisted solution; an ML pipeline may include one or several data sources in a data pipeline, a model training pipeline, a model evaluation pipeline, and an actor. The “actor” is an entity that hosts an ML assisted solution using the output of the ML model inference). The term “ML training host” refers to an entity, such as a network function, that hosts the training of the model. The term “ML inference host” refers to an entity, such as a network function, that hosts model during inference mode (which includes both the model execution as well as any online learning if applicable). The ML-host informs the actor about the output of the ML algorithm, and the actor takes a decision for an action (an “action” is performed by an actor as a result of the output of an ML assisted solution). The term “model inference information” refers to information used as an input to the ML model for determining inference(s); the data used to train an ML model and the data used to determine inferences may overlap, however, “training data” and “inference data” refer to different concepts.
