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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a slot or a symbol where a channel state information reference signal (CSI-RS) for a Procedure 2 (P2) resource is to be scheduled. The UE may schedule a candidate UE beam or a serving UE beam for the slot or the symbol. The UE may measure a spectral efficiency associated with the P2 resource. The UE may prepare a report that indicates one or more characteristics of the candidate UE beam or the serving UE beam. Numerous other aspects are described.

Abstract: A UE performs a cell search based on a synchronization raster in an operating band in frequency, the synchronization raster having a valid range and an SSB search with a step size greater than one based on a channel raster range of a channel raster within the operating band, a duplex mode of the operating band, a bandwidth of an SSB, and a minimum guard band size, and select a cell based on the cell search. A network node may be configured to transmit an SSB for a cell at a frequency based on a synchronization raster in an operating band, the synchronization raster having a valid range based on a channel raster range of a channel raster within the operating band, a duplex mode of the operating band, a bandwidth of the SSB, and a minimum guard band size, and communicate with at least one UE via the cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a modification to a maximum output power associated with the UE. For example, the UE may determine to apply ΔPPowerClass to modify the maximum output power PCMAX,c. Accordingly, the UE may transmit a power headroom report (PHR) based on the modification to the maximum output power. For example, the UE may transmit the PHR based on an uplink/downlink configuration for a cell serving the UE. Alternatively, the UE may transmit the PHR based on an uplink duty cycle threshold, associated with the UE, being satisfied . Numerous other aspects are described.

Abstract: A user equipment (UE) may spatial time-division multiplex a plurality of sounding reference signal (SRS) ports, each of the plurality of SRS ports being associated with at least one of a set of orthogonal weights, the set of orthogonal weights corresponding to phase shifting, and transmit a plurality of SRSs via the plurality of spatially time-division multiplexed SRS ports simultaneously, each of the plurality of SRSs including at least two SRS repetition. The plurality of SRSs may be configured to form or present a quasi-co-location (QCL) receive (Rx) beam subspace. The UE may configure the plurality of SRSs to form the subspace as the QCL Rx beam subspace, and a base station may signal the UE to a specific Rx beam subspace such that it is aligned to the base station's beamforming direction, and achieve spatial multiplexing gain in the QCL Rx beam subspace.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, information configuring an active bandwidth part (BWP) that does not include a bandwidth associated with one or more of a synchronization signal block (SSB) or a control resource set zero (CS0). The UE may perform, based at least in part on a radio frequency (RF) retune mode, an RF retune to a union bandwidth that covers the active BWP and the bandwidth associated with one or more of the SSB or the CS0. Numerous other aspects are described.

Abstract: The base station may transmit to the UE, a first part and a second part of a PDSCH. The UE may decode the second part of the PDSCH. The first part of the PDSCH may be associated with a higher MCS than the second part of the PDSCH. The UE may estimate at least one of an ICI or a CPE associated with the PDSCH based on the decoding of the second part of the PDSCH. The UE may decode the first part of the PDSCH based on the decoding of the second part of the PDSCH. Decoding the first part of the PDSCH based on the decoding of the second part of the PDSCH may include correcting for the at least one of the ICI or the CPE associated with the PDSCH.

Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for cancelling transmissions during handover operations. In one aspect, a user equipment (UE) can cancel at least a portion of a first uplink transmission where the first uplink transmission overlaps with a second uplink transmission scheduled by a target cell in a dual active protocol stack (DAPS)-based handover (HO). In another aspect, a network can receive, from the UE, a capability indicating whether cancelling uplink transmission from a source cell in DAPS-based HO is supported, and the network can schedule an uplink transmission for the UE during the DAPS-based HO to the target cell based on the capability.
