Abstract: Various aspects relate to scheduling reference signals across multiple carriers (e.g., across cells). Signaling may be used to indicate whether reference signals are scheduled across multiple carriers. For example, a single instance of downlink control information (e.g., the downlink control information sent via a single time slot) that schedules multiple carriers (e.g., multiple component carriers) may include an indication of whether reference signals are scheduled for two or more of the scheduled carriers.

Abstract: Aspects of the disclosure relate to a method of wireless communication. An exemplary method includes formatting a first downlink control information (DCI) to schedule a first plurality of physical downlink shared channels (PDSCHs) in a first plurality of cells and transmitting the first DCI in a first physical downlink control channel (PDCCH) to a scheduled entity. Another method includes identifying a search space in a resource element grid within which a control region set (CORESET) is located, decoding the CORESET to obtain a first downlink control information (DCI), determining, from the first DCI, locations in the resource element grid that contain a first plurality of physical downlink shared channels (PDSCHs) in a first plurality of cells scheduled for use of the scheduled entity, and decoding data located in the first plurality of PDSCHs. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication that is scheduled to be transmitted by a plurality of physical uplink repetitions in multiple slots on a plurality of beams is subject to a maximum permissible exposure (MPE) condition. The UE may determine a transmission adjustment for the plurality of physical uplink repetitions on the plurality of beams, based at least in part on a determination that the uplink communication is subject to the MPE condition, and transmit the uplink communication based at least in part on the transmission adjustment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information that identifies a first precoder indicator selected from a set of precoder indicators and a second precoder indicator selected from a subset of the set of precoder indicators. The UE may communicate using multiple antenna panels based at least in part on the first precoder indicator and the second precoder indicator. Numerous other aspects are provided.

Abstract: An apparatus receives at least one scheduling grant scheduling transmission on a first data channel and further scheduling a second data channel. The apparatus reduces a transmit power for the transmission on the first data channel with a first beam when a radio frequency (RF) exposure event occurs. The apparatus increases, after the RF exposure event occurs, a transmit power for the transmission on the second data channel with a second beam. The apparatus transmits an RF exposure report associated with at least one of the first data channel or the first beam to the base station.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication at a user equipment, including receiving on a physical downlink control channel (PDCCH) during a first PDCCH monitoring occasion a first downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH) for each of at least two component carriers, wherein the DCI includes a counter downlink assignment index (DAI) that indicates a number of scheduled PDSCHs up to a point that the first DCI was received and a total DAI indicating a number of scheduled PDSCHs across the at least two component carriers. The implementations further include transmitting a physical uplink control channel (PUCCH) including a position for hybrid automatic repeat request (HARQ)-Acknowledgement (ACK) bits corresponding to the PDSCH for each of the at least two component carriers. Also included is a corresponding a method, apparatus and computer-readable medium of wireless communication at a base station.

Abstract: Certain aspects of the present disclosure provide techniques for communicating using power control parameters for multiple transmitter receiver point (mTRP) physical uplink shared channel (PUSCH) repetition. A method that may be performed by a user equipment (UE) includes receiving a sounding reference signal (SRS) configuration indicating at least a first SRS resource set and at least a second SRS resource set, receiving downlink control information (DCI) scheduling a first set of one or more PUSCH repetitions to a first TRP and a second set of one or more PUSCH repetitions to a second TRP, and transmitting the first and second sets of PUSCH repetitions using at least one of a first set of default power control parameters or a second set of default power control parameters.
