Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a first configuration and a second configuration, wherein the first configuration is for a discontinuous reception (DRX) cycle and the second configuration is for a configured grant (CG), wherein the DRX cycle is associated with a set of active time durations and a set of non-active time durations, and wherein the CG is associated with a transmission in one or more non-active time durations of the set of non-active time durations; receive information identifying a mask, wherein the mask indicates a modified configuration for the transmission in the one or more non-active time durations or a modified multiplexing scheme for the CG; and selectively perform or skip the transmission in accordance with the CG and the mask. 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 receive a physical downlink control channel (PDCCH) communication in a first dynamic control resource set (CORESET) configured in a first bandwidth part (BWP). The PDCCH communication may indicate a BWP switch from the first BWP to a second BWP. The UE may determine, based at least in part on the BWP switch, whether to monitor one or more second dynamic CORESETs, subsequent to the first dynamic CORESET, that were configured in the first BWP. The UE may selectively monitor the one or more second dynamic CORESETs based at least in part on determining whether to monitor the one or more second dynamic CORESETs. 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 receive a physical random access channel (PRACH) preamble configuration that indicates a first preamble format for a first PRACH preamble and a second preamble format for a second PRACH preamble, wherein the first preamble format is different from the second preamble format. The UE may transmit the first PRACH preamble as part of a random access procedure based at least in part on the PRACH preamble configuration, wherein transmitting the first PRACH preamble enables a determination of a symbol boundary offset. The UE may transmit the second PRACH preamble as part of the random access procedure based at least in part on the PRACH preamble configuration, wherein transmitting the second PRACH preamble enables a determination of a symbol timing offset. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform respective measurements of one or more demodulation reference signals (DMRSs). Each of the one or more DMRSs may be associated with a repetition of a downlink transmission. Each of the one or more DMRSs may be transmitted on a narrow beam that is located within a wide beam associated with a transmission configuration indication indicated in a grant for the downlink transmission. The UE may transmit an indication of one or more of the respective measurements. Numerous other aspects are provided.

Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may generate a frequency-domain-multiplexed signal by performing frequency domain multiplexing of a data signal and a reference signal within a symbol of a discrete Fourier transform spread orthogonal frequency domain multiplexing waveform communication, the reference signal being one of a demodulation reference signal, a sounding reference signal, or a channel state information reference signal. The transmitting device may transmit, to a receiving device, the frequency-domain-multiplexed signal. Numerous other aspects are described.
