CLAIM OF PRIORITY

[0001] The present application claims priority under 35 U.S.C. § 119(e) to United

States Provisional Patent Application Serial Number 62/205,535 filed August 14, 2015 and entitled "Methods For CQI Feedback And RRM Measurements With Dynamic Power Sharing Among Multiple LAA SCells For DL-Only Transmission," which is herein incorporated by reference in its entirety.

BACKGROUND

[0002] Various wireless cellular communication systems have been implemented or are being proposed, including a 3rd Generation Partnership Project (3GPP) Universal Mobile Telecommunications System (UMTS), a 3GPP Long-Term Evolution (LTE) system, a 3GPP LTE-Advanced (LTE-A) system, and a 5th Generation wireless / 5th Generation mobile networks (5G) system. Each wireless cellular communication system may support a variety of features. For example, one feature supported by LTE-A is Carrier Aggregation (CA), in which a Primary Cell (PCell) and one or more Secondary Cells (SCells) may be Component Carriers (CCs), and may aggregate their various bandwidths to provide better Downlink (DL) performance to User Equipments (UEs). For DL operation, LTE-A SCells may be based upon fixed transmission power for Downlink (DL) operation, or transmission power that may be statically maintained between occasional changes.

[0003] Meanwhile, another feature supported by various wireless cellular communications systems is the use of unlicensed bands or unlicensed spectrum under License-Assisted Access (LAA). LTE-A SCells may use unlicensed spectrum under LAA. When using unlicensed bands, however, maximum transmission power may be limited by regulatory bodies for the entire unlicensed band, independent of the number of CCs used for transmission or the transmission bandwidth used for transmission.

DETAILED DESCRIPTION

[0015] Some wireless cellular communication systems may support Carrier

Aggregation (CA) in which a Primary Cell (PCell) interoperates with one or more Secondary Cells (SCells), each acting as a Component Carrier (CC) contributing to an aggregated Downlink (DL) bandwidth to various User Equipments (UEs). In licensed spectrum, SCells may operate under fixed or semi-static transmission power per SCell.

[0016] Meanwhile, when using unlicensed bands, maximum transmission power for an entire unlicensed band may be regulated. Moreover, the maximum transmission power may vary between different bandwidths or portions of spectrum. As an initial example, in indoor operation, a maximum transmission power may be limited to 23 dBm for operation in the 5150 MHz to 5250 MHz band or the 5250 MHz to 5350 MHz band, regardless of the number of CCs in use or the bandwidth being used by CCs.

[0017] As a further example, in WiFi operation, a transmission power on each carrier for each transmission may be dynamically modified based upon a number of channels used for channel bonding by equally sharing the transmission power across the number of channels used. Under various transmission constraints for operation in the 5150 MHz to 5250 MHz band or the 5250 MHz to 5350 MHz band, for 20 MHz transmission, up to 23 dBm transmission power may be used; for 40 MHz transmission, each channel may use a transmission power of up to 20 dBm; and for 80 MHz transmission, each channel may use a transmission power of up to 17 dBm.

[0018] SCells operating in unlicensed spectrum or unlicensed bands, such as SCells operating under License- Assisted Access (LAA), may also be constrained to not exceed a total per-channel power budget. These power constraints may apply regardless of the number of CCs aggregating in that channel or the bandwidth those CCs support. In order to operate within regulatory constraints upon power usage, SCells operating under LAA in situations in which multiple CCs may be used for DL burst transmissions may accordingly be disposed to dynamically sharing power.

[0019] However, channel quality may be indicated not merely by a signal's power as measured by a receiver, but by a difference between the signal's power when transmitted and the signal's power when received. As a result, under conditions in which transmission power is dynamic, more meaningful Channel Quality Indication (CQI) measurements and Radio Resource Management (RMM) measurements may depend upon a power used in transmitting various signals being measured. Various mechanisms and methods for facilitating better link-quality measurements for SCells engaging in dynamic power sharing are discussed below. [0020] In the following description, numerous details are discussed to provide a more thorough explanation of embodiments of the present disclosure. It will be apparent to one skilled in the art, however, that embodiments of the present disclosure may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring embodiments of the present disclosure.

[0021] Note that in the corresponding drawings of the embodiments, signals are represented with lines. Some lines may be thicker, to indicate a greater number of constituent signal paths, and/or have arrows at one or more ends, to indicate a direction of information flow. Such indications are not intended to be limiting. Rather, the lines are used in connection with one or more exemplary embodiments to facilitate easier understanding of a circuit or a logical unit. Any represented signal, as dictated by design needs or preferences, may actually comprise one or more signals that may travel in either direction and may be implemented with any suitable type of signal scheme.

[0022] Throughout the specification, and in the claims, the term "connected" means a direct electrical, mechanical, or magnetic connection between the things that are connected, without any intermediary devices. The term "coupled" means either a direct electrical, mechanical, or magnetic connection between the things that are connected or an indirect connection through one or more passive or active intermediary devices. The term "circuit" or "module" may refer to one or more passive and/or active components that are arranged to cooperate with one another to provide a desired function. The term "signal" may refer to at least one current signal, voltage signal, magnetic signal, or data/clock signal. The meaning of "a," "an," and "the" include plural references. The meaning of "in" includes "in" and "on."

[0023] The terms "substantially," "close," "approximately," "near," and "about" generally refer to being within +/- 10% of a target value. Unless otherwise specified the use of the ordinal adjectives "first," "second," and "third," etc., to describe a common object, merely indicate that different instances of like objects are being referred to, and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking, or in any other manner.

[0024] It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in other orientations than those illustrated or otherwise described herein. [0025] The terms "left," "right," "front," "back," "top," "bottom," "over," "under," and the like in the description and in the claims, if any, are used for descriptive purposes and not necessarily for describing permanent relative positions.

[0026] For purposes of the embodiments, the transistors in various circuits, modules, and logic blocks are Tunneling FETs (TFETs). Some transistors of various embodiments may comprise metal oxide semiconductor (MOS) transistors, which include drain, source, gate, and bulk terminals. The transistors may also include Tri-Gate and FinFET transistors, Gate All Around Cylindrical Transistors, Square Wire, or Rectangular Ribbon Transistors or other devices implementing transistor functionality like carbon nanotubes or spintronic devices. MOSFET symmetrical source and drain terminals i.e., are identical terminals and are interchangeably used here. A TFET device, on the other hand, has asymmetric Source and Drain terminals. Those skilled in the art will appreciate that other transistors, for example, Bi-polar junction transistors-BJT PNP/NPN, BiCMOS, CMOS, etc., may be used for some transistors without departing from the scope of the disclosure.

[0027] For the purposes of the present disclosure, the phrases "A and/or B" and "A or

B" mean (A), (B), or (A and B). For the purposes of the present disclosure, the phrase "A, B, and/or C" means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C).

[0028] In addition, the various elements of combinatorial logic and sequential logic discussed in the present disclosure may pertain both to physical structures (such as AND gates, OR gates, or XOR gates), or to synthesized or otherwise optimized collections of devices implementing the logical structures that are Boolean equivalents of the logic under discussion.

[0029] Fig. 1 illustrates a scenario of a plurality of Secondary Cells (SCells) with overlapping coverage areas, in accordance with some embodiments of the disclosure. A wireless cellular communications scenario 100 includes a plurality of Evolved Node-Bs (eNBs) 110. Each eNB 110 may provide wireless cellular communications services within a cell 120 extending over a geographic area. Some cells 120 may extend into geographic areas that overlap geographic areas into which other cells 120 extend.

[0030] In scenario 100, a plurality of User Equipments (UEs) 130 may interact with eNBs 110 to make use of the cellular services. eNBs 110 may be base stations operable within one or more of: a 3rd Generation Partnership Project (3GPP) Universal Mobile Telecommunications System (UMTS) system; a 3GPP Long-Term Evolution (LTE) system; a 3GPP LTE-Advanced (LTE-A) system; and a 5th Generation wireless / 5th Generation mobile networks (5G) system. Similarly, UEs 130 may accordingly be operable within one or more of a UMTS system, an LTE system, an LTE-A system, and a 5G system.

[0031] Based upon the partially overlapping nature of cells 120, some UEs 131 may be situated in geographic areas within a cell 120 served by a single eNB 110. Other UEs 132 may be situated in geographic areas within two cells 120 served by two eNBs 110, while still other UEs 133 may be situated in geographic areas within three cells 120 served by three eNBs 110.

[0032] eNBs 110 may comprise SCells in a CA scenario, and may be CCs interoperating with a PCell to contribute to an aggregated DL bandwidth for various UEs. In addition, eNBs 110 may at least partially operate in unlicensed spectrum or unlicensed bands. Accordingly, eNBs 110 may engage in dynamic power sharing among each other in order to operate under regulatory power limits, and may benefit from mechanisms and methods for facilitating more meaningful link-quality measurements. Meanwhile, maximum transmission power may vary between different bandwidths or portions of spectrum.

A. CSI measurement and reporting

[0033] Dynamic power sharing among multiple SCells may impact Channel State

Information (CSI) reporting and link adaptation at an eNB. For example, an eNB 110 may transmit various Cell-specific Reference Signals (CRS) and/or CSI Reference Signals (CSI- RS) used for CSI measurements, and a UE 130 may then receive the CRS and/or CSI-RS signals and use them for CSI measurements.

[0034] Due to dynamic power sharing, eNB 110 may transmit the signals under conditions of varying transmission power, and UE 130 may measure the signals as having varying power. However, the varying power of the signals received at UE 130 may merely reflect the varying power used to transmit the signals, and may not reflect a variance in the link quality. As a result, such variances in received power may potentially cause

inconsistencies in reported CSI feedback.

[0035] These potential inconsistencies in reported CSI feedback may be corrected either at an eNB or at a UE. For correction at an eNB, in some embodiments, eNB 110 may have information before-hand regarding a transmission power used for a CRS transmission or a CSI-RS transmission that UE 130 subsequently uses for purposes of CQI feedback.

Accordingly, eNB 110 may scale a reported CSI received from UE 130, based upon a transmission power for the transmission. For example, an unsealed transmission power (such as a transmission power in the absence of dynamic power sharing) may be Xi, a transmission power causing the reported CSI may be ¾, and a reported CSI may be Y ₂ . In such cases, a scaled reported CSI Yi may be substantially equal to Y2 divided by X2 and multiplied by Xi.

[0036] In such embodiments, UE 130 may refrain from applying any filtering for computing CSI feedback, and may instead compute CSI feedback based upon an unfiltered signal. When computing CSI feedback based upon an unfiltered signal, UE 130 may not compute the CSI feedback across multiple subframes, and/or may not compute the CSI feedback for multiple references signals. Instead, UE 130 may compute the CSI feedback across one subframe, and/or for one reference signal.

[0037] For some embodiments of correction at a UE, a number of CCs being used for

DL transmission may be explicitly signaled to UE 130. For some such embodiments, an eNB 110 acting as a PCell may indicate to UE 130 a number of CCs used for ongoing

transmissions on an unlicensed band. Downlink Control Information (DCI) from a licensed carrier (e.g., the eNB 110 acting as a PCell) may indicate a number of CCs used for a previous sub-frame, or a number of CCs used for an ongoing burst on an unlicensed carrier. In such embodiments, DCI may explicitly indicate one or more of the following:

a scaling factor indicating a ratio of actual transmission power to maximum transmission power for a CRS transmission;

a list of active SCells (such as SCells participating in an ongoing transmission or an ongoing burst); and

a transmission power used for a CRS transmission and/or a CSI-RS transmission, for each CC, where unequal power transmission among the CCs is used.

[0038] The list of active SCells or CCs participating in an ongoing transmission or an ongoing burst, and/or a number of active SCells or CCs participating in an ongoing transmission or an ongoing burst, may be determined at a predetermined time before the transmission of a reference signal, or within a predetermined window of time before the transmission of the reference signal, or at substantially the same time as the transmission of the reference signal.

[0039] The transmission power indicated by DCI may be a transmission power for each CC, or an average transmission power over the CCs. For other embodiments of correction at a UE, eNB 110 acting as an SCell may explicitly indicate a transmission power to UE 130 by transmitting an initial signal before transmission of a DL burst on one or more active SCells, up to and including all active SCells. The initial signal may indicate one or more of the following: a scaling factor indicating a ratio of actual transmission power to maximum transmission power for a CRS transmission;

a list of SCells used for a data burst transmission; and

a transmission power for each CC.

[0040] In some embodiments, one SCell may indicate information to a UE on behalf of other SCells. In such embodiments, UE 130 may determine a number of SCells used for a current data burst or subframe on an unlicensed band by a presence of Physical Downlink Control Channel (PDCCH) on configured CCs.

[0041] The list of SCells used for a data burst transmission, and/or a number of

SCells used for a data burst transmission, may be determined at a predetermined time before the transmission of a reference signal, within a predetermined window of time before the transmission of a reference signal, or at substantially the same time as the transmission of the reference signal.

[0042] An SCell may have information regarding a maximum transmission power for a bandwidth or portion of spectrum in which various configured CCs may operate, and/or a maximum number of CCs that may operate within the bandwidth or portion of spectrum based upon the maximum transmission power. Since the maximum transmission power may vary between different bandwidths or portions of spectrum, the number of CCs that may operate within a bandwidth or portion of spectrum may vary between different bandwidths or portions of spectrum.

[0043] Common search space may also be modified to be enabled for LAA SCells.

In addition, to reduce UE complexity, an aggregation level may be fixed, or possible aggregation levels may be reduced. The particular SCells that a UE may monitor in common search space may also be limited, in a UE-specific manner.

B. RRM measurement and reporting

[0044] Under LAA, RRM measurements may be performed based upon a single

Demodulation Reference Signal (DRS) occasion. Due to dynamic power sharing, eNB 110 may transmit DRS signals under conditions in which transmission power may vary across DRS occasions, and UE 130 may measure the DRS signals as having varying power across DRS occasions. However, the varying power of the DRS signals received at UE 130 may merely reflect the varying power used to transmit the signals, and may not reflect a variance in link quality across the DRS occasions. As a result, the variance in received power may potentially cause UE 130 to generate inconsistent RRM reports. [0045] These potential inconsistencies in reported RRM may be corrected in various ways. In a first set of embodiments, DRS transmission power may be maintained or fixed at a constant level that may be independent of a number of CCs used at the time of DRS transmission. The DRS transmission power may accordingly be fixed to be within regulations, and may be invariant with respect to a number of active LAA CCs. In such embodiments, a variance across DRS occasions of the power of DRS signals received at UE 130 may reflect a variance in link quality across DRS occasions.

[0046] In a second set of embodiments, DRS transmission power may vary across

DRS occasions depending upon a number of available channels. Since Layer 3 (L3) filtering of measured values may resemble averaging across multiple subframes, RRM reports may not be accurate when L3 filtering is applied. Accordingly, in such embodiments, L3 filtering might not be applied for RRM measurements.

[0047] For some of the second set of embodiments, an SCell may explicitly indicate a

DRS transmission power for each DRS occasion through Layer 1 (LI) signaling. The signal may be transmitted using a Physical Downlink Control Channel (PDCCH), an Enhanced PDCCH (EPDDCH), or a new control channel. Since LI signaling may provide an actual DRS transmission power from an eNB to a UE, one or more SCells in a group of aggregated CCs may independently indicate a DRS transmission power to the same UE. The UE may then determine a correct power for an RRM report, based on the indicated DRS transmission power.

[0048] Alternatively, an SCell may indicate a number of CCs used for DRS transmission, in which case the UE may determine a corrected power for an RRM report based upon a splitting of DRS transmission power among the various CCs serving the UE.

[0049] For others of the second set of embodiments, an SCell might not explicitly indicate a DRS transmission power through LI signaling. Instead, a UE may measure RRM based upon a single DRS occasion, as a design target of LAA.

[0050] In some such embodiments, DRS and/or RRM measurement reports may be transmitted periodically, and there may be a timing relationship between a DRS subframe and an RRM report. An eNB receiving an RRM measurement report may then determine a corrected transmission power based upon information the eNB possesses regarding the transmission power used for the DRS transmission used by the UE for preparing the RRM measurement report. In other such embodiments, event-driven RRM measurements may be based upon DRS transmissions from single DRS occasions. [0051] In a third set of embodiments, DRS occasions for different CCs may be separated in time, which may enable full DRS transmission power. RRM measurements may then be based on standalone DRS transmission.

Some of the actions and/or operations listed in Figs. 6-7 and 10 are optional in accordance with certain embodiments. The numbering of the actions presented is for the sake of clarity and is not intended to prescribe an order of operations in which the various actions must occur.

Additionally, operations from the various flows may be utilized in a variety of combinations.

[0063] Moreover, in some embodiments, machine readable storage media may have executable instructions that, when executed, cause eNB 210 and/or hardware processing circuitry 220 to perform an operation comprising any of the methods of Figs. 6 and 10.

D. Example hardware processing circuitries and methods - supporting CSI

measurement and reporting under LAA with dynamic power sharing [0064] Fig. 3 illustrates hardware processing circuitries for an eNB for supporting

Channel State Information (CSI) measurement and reporting under License Assisted Access (LAA) with dynamic power sharing, in accordance with some embodiments of the disclosure. A hardware processing circuitry 300 may comprise logic devices and/or circuitry operable to perform various operations. For example, with reference to Figs. 2 and 3, eNB 210 (or various elements or components therein, such as hardware processing circuitry 220, or combinations of elements or components therein) may include part of, or all of, hardware processing circuitry 300. In some embodiments, processor 216 and memory 218 (and/or other elements or components of eNB 210) may be arranged to perform the operations of hardware processing circuitry 300, such as operations described herein with reference to devices and circuitry within hardware processing circuitry 300. For example, one or more devices or circuits of hardware processing circuitry 300 may be implemented by

combinations of software-configured elements and/or other hardware elements.

[0065] In some embodiments, hardware processing circuitry 300 may comprise one or more antenna ports 305 operable to provide various transmissions over a wireless communication channel (such as wireless communication channel 250). Antenna ports 305 may be coupled to one or more antennas 307 (which may be antennas 205). In some embodiments, hardware processing circuitry 300 may incorporate antennas 307, while in other embodiments, hardware processing circuitry 300 may merely be coupled to antennas 307.

[0066] Antenna ports 305 and antennas 307 may be operable to provide signals from an eNB to a wireless communications channel and/or a UE, and may be operable to provide signals from a UE and/or a wireless communications channel to an eNB. For example, antenna ports 305 and antennas 307 may be operable to provide transmissions from eNB 210 to wireless communication channel 250 (and from there to UE 230, or to another UE).

Similarly, antennas 307 and antenna ports 305 may be operable to provide transmissions from a wireless communication channel 250 (and beyond that, from UE 230, or another UE) to eNB 210.

[0067] An apparatus of eNB 210 (or another eNB or base station) may be operable to communicate with UE 230 (or another UE or mobile equipment) on a wireless network, and may comprise hardware processing circuitry 300. In some embodiments, the eNB (or other base station) may be a device comprising an application processor, a memory, one or more antenna ports, and an interface for allowing the application processor to communicate with another device.

[0068] With reference to Fig. 3, hardware processing circuitry 300 may comprise a first circuitry 310, a second circuitry 320, a third circuitry 330, and a fourth circuitry 340. First circuitry 310 may be operable to provide a maximum number of CCs and a number of active CCs over an interface 315. In some embodiments, the maximum number of CCs may include a Primary Cell PCell and one or more SCells. In various embodiments, the number of active CCs may be determined, for some embodiments, at substantially the same time as the transmission of the reference signal.

[0069] Second circuitry 320 may be operable to transmit a reference signal to UE

230. In various embodiments, the reference transmission may be either a CRS transmission or a CSI-RS transmission.

[00122] In some embodiments, the mixer circuitry 1106a of the receive signal path and the mixer circuitry 1 106a of the transmit signal path may include two or more mixers and may be arranged for quadrature downconversion and/or upconversion respectively. In some embodiments, the mixer circuitry 1 106a of the receive signal path and the mixer circuitry 1 106a of the transmit signal path may include two or more mixers and may be arranged for image rej ection (e.g., Hartley image rejection).

[00126] The synthesizer circuitry 1 106d may be configured to synthesize an output frequency for use by the mixer circuitry 1106a of the RF circuitry 1 106 based on a frequency input and a divider control input. In some embodiments, the synthesizer circuitry 1106d may be a fractional N/N+l synthesizer.

[00127] In some embodiments, frequency input may be provided by a voltage controlled oscillator (VCO), although that is not a requirement.

[00128] Synthesizer circuitry 1106d of the RF circuitry 1106 may include a divider, a delay-locked loop (DLL), a multiplexer and a phase accumulator. In some embodiments, the divider may be a dual modulus divider (DMD) and the phase accumulator may be a digital phase accumulator (DPA).

The FEM circuitry may include a receive signal path and a transmit signal path. The receive signal path of the FEM circuitry may include a low-noise amplifier (LNA) to amplify received RF signals and provide the amplified received RF signals as an output (e.g., to the RF circuitry 1106).

[00132] In some embodiments, the UE 1100 comprises a plurality of power saving mechanisms. If the UE 1100 is in an RRC Connected state, where it is still connected to the eNB as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the device may power down for brief intervals of time and thus save power.

[00133] If there is no data traffic activity for an extended period of time, then the UE

1 100 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The UE 1100 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. Since the device might not receive data in this state, in order to receive data, it should transition back to RRC Connected state. [00134] An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.

[00135] Reference in the specification to "an embodiment," "one embodiment," "some embodiments," or "other embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments. The various appearances of "an embodiment," "one embodiment," or "some embodiments" are not necessarily all referring to the same embodiments. If the specification states a component, feature, structure, or characteristic "may," "might," or "could" be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to "a" or "an" element, that does not mean there is only one of the elements. If the specification or claims refer to "an additional" element, that does not preclude there being more than one of the additional element.

[00136] Furthermore, the particular features, structures, functions, or characteristics may be combined in any suitable manner in one or more embodiments. For example, a first embodiment may be combined with a second embodiment anywhere the particular features, structures, functions, or characteristics associated with the two embodiments are not mutually exclusive.
