Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an AMF may receive, from a user equipment (UE), a communication associated with a request for an identifier. The AMF may transmit, to the UE, the identifier, wherein the identifier is based at least in part on a synchronization signal block (SSB) periodicity and a number of paging frames per discontinuous reception (DRX) cycle. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method for wireless communications at a user equipment (UE) includes determining one or more performance metrics related to communications over a wireless channel and comparing the one or more performance metrics with a performance level for the communications over the wireless channel. The method may include selecting a power mode for the UE based at least in part on the comparing and determining an operating state of a subset of a plurality of radio frequency front end elements of at least one active radio frequency chain of the UE based at least in part on the power mode and a priority of the one or more performance metrics. The method may also include adjusting the subset of the plurality of radio frequency front end elements based at least in part on the operating state.

Abstract: Apparatus, methods, and computer-readable media for facilitating multi-tasking and smart location selection during connected-mode discontinuous reception (CDRX) mode are disclosed herein. Example techniques disclosed herein enable a UE to perform multiple tasks during a same SSBS to reduce the number of wake-up SSBSs. For example, disclosed techniques enable a UE to perform RLM tasks and loop tracking tasks during a first SSBS and thereby reduce the number of wake-up SSBSs. In some examples, the UE may also perform the search task or the measurement task during the same first SSBS and, thereby, further reduce the number of wake-up SSBSs. Example techniques disclosed herein may also enable the UE to select which SSBS occurrences to wake-up for during the OFF duration of the CDRX cycle.

Abstract: Methods, systems, and devices for wireless communications are described that provide for antenna selection at a user equipment (UE). The UE may have a set of available antennas for uplink and downlink communications, and may select a first subset of antennas for uplink communications and a second subset of antennas for downlink communications. The first subset of antennas may be based on one or more uplink metrics, and the second subset of antennas may be based on the first subset of antennas and one or more downlink channel metrics, traffic amounts, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information message scheduling a downlink transmission that comprises a zero-power reference signal for the UE to use for rate matching during the downlink transmission. The UE may receive a signal triggering transmission of an aperiodic reference signal during the downlink transmission. The UE may determine whether the UE supports search space sharing. The UE may perform, upon determining that the UE supports search space sharing, rate matching around the aperiodic reference signal.

Abstract: Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit a sounding reference signal (SRS) to a base station using an SRS antenna switch (SRS-AS) or an SRS carrier switch (SRS-CS) transmission technique and the UE may feature multiple antenna groups that have separate exposure budgets due to their spatial separation. The UE may employ one or more accounting procedures for tracking energy contributions associated with the SRS across the multiple antenna groups of the UE and may employ one or more power control procedures for setting a transmit power for an uplink signal in accordance with the energy contributions associated with the SRS.

Abstract: A device may selectively listen for a tracking reference signal (TRS) during connected mode discontinuous reception (CDRx) based on whether the device is to switch between repeaters of a base station (such as during travel). A device may determine whether the device is in a high speed train (HST) scenario (such as based on a difference in frequency errors generated using a synchronization signal block (SSB) and generated using a TRS, based on a trajectory of a frequency error or a frequency error difference over time, based on instantaneous frequency errors, etc.). When the device is in a HST scenario, the device listens for a TRS during CDRx, and the device generates a frequency error using the TRS. When the device is not in a HST scenario, the device prevents listening for a TRS during CDRx (with a SSB received during CDRx to be used to generate a frequency error).

Abstract: The present disclosure relates to transmitting and receiving a beam report at a UE and a base station. The base station can configure a cDRX cycle with the UE. Also, the UE can wake up during an off period of the cDRX cycle. The UE can also compare a first metric of at least one of a plurality of candidate beams and a second metric of a current beam for communication with the base station. Additionally, the UE can transmit a beam report to the base station, during the off period, based on the comparison of the first metric of the at least one of the plurality of candidate beams and the second metric of the current beam. The UE can also select, during the off period of the cDRX cycle, the at least one of the plurality of candidate beams for communication with the base station.

Abstract: Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.
