Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more time slots in which a first communication on a multi-slot physical uplink control channel (PUCCH) overlaps with a second communication on another PUCCH. The UE may transmit, for each time slot of the one or more time slots, the first communication or the second communication based at least in part on a first priority assigned to the multi-slot PUCCH and a second priority assigned to the other PUCCH. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, when operating in a multiple link communication system, one or more downlink control information (DCI) messages scheduling one or more downlink communications. The user equipment may determine, based at least in part on the one or more DCI messages, whether a communication constraint is satisfied for the one or more downlink communications. The user equipment may determine a communication configuration for the one or more downlink communications based at least in part on whether the communication constraint is satisfied. The user equipment may receive, in the multiple link communication system, the one or more downlink communications based at least in part on the communication configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a phase tracking reference signal (PTRS) port is to be shared among a plurality of physical downlink shared channels (PDSCHs) transmitted by a plurality of transmit receive points (TRPs); receive PTRS pilot signals on one or more PDSCHs of the plurality of PDSCHs; and use the PTRS pilot signals for phase tracking estimation for the plurality of PDSCHs based at least in part on the determination that the PTRS port is to be shared among the plurality of PDSCHs. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions. In some cases, a UE may determine a transmit power budget, receiving signaling indicating how to allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, and transmitting the PUSCH using the transmit chains according to the determined transmit power allocation.

Abstract: Certain aspects of the present disclosure provide apparatus and method for wireless communication. For example, the method generally includes receiving signaling indicating a first subframe configuration, the first subframe configuration corresponding to a subframe with a first number of symbols in an uplink pilot time slot (UpPTS), receiving signaling indicating a second configuration, the second configuration indicating a second number of symbols in the UpPTS, generating a frame comprising the UpPTS having the first number of symbols corresponding to the first subframe configuration, the UpPTS including one or more SRSs corresponding to the second configuration, and transmitting the frame comprising the UpPTS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine at least one of a downlink path loss value or an uplink path loss value associated with a base station; receive system information, a semi-persistently configured grant via RRC or a dynamic uplink grant via DCI from the base station, wherein the RRC signaling or the dynamic uplink grant identifies a power control value associated with one user or a plurality of users associated with the base station; and determine a transmit power for a data or control transmission based at least in part on at least one of the downlink path loss value or the uplink path loss value and the power control value. Numerous other aspects are provided.

Abstract: The present disclosure relates to reducing control overhead in a wireless communication system. For example, a network entity may determine to transmit data according to a codeword format based on at least one of a transmission time interval (TTI), or a traffic type of the data, or any combination thereof, and configure the data for transmission on a communication channel according to the codeword format. Further, for instance, a user equipment may receive a transmission from a network entity on a downlink communication channel according to a codeword format, and transmit at least one of an acknowledgement (ACK) or a negative acknowledgement (NACK) on an uplink communication channel in response to receiving the transmission from the network entity.

Abstract: Various aspects described herein relate to communicating in a wireless network. A resource grant comprising an indicator of whether to transmit a demodulation reference signal (RS) for an uplink control channel or an uplink data channel can be received from a network entity. It can be determined whether to transmit the RS in at least one transmission time interval (TTI) based at least in part on the indicator.
