Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a capability of the UE to communicate one or more of uplink communications or downlink communications that include data-modulated demodulation reference signals (DMRSs) in which each of one or more resources of a plurality of resources of the uplink communications or the downlink communications carry both at least a portion of a DMRS sequence and data. The UE may transmit an uplink communication or receive a downlink communication that includes the data-modulated DMRSs. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may map a code block to resources, of a physical shared channel, that are allocated for data-modulated demodulation reference signals (DMRSs) in which each of the resources carries both at least a portion of a DMRS sequence and data. The wireless communication device may transmit a communication, via the physical shared channel, that includes the code block that is mapped to the resources that are allocated for the data-modulated DMRSs. Numerous other aspects are provided.

Abstract: In a channel occupancy time (COT), a scheduling entity can transmit a first downlink (DL) transmission burst to a scheduled entity, and receive an uplink (UL) transmission burst from the scheduled entity. The scheduling entity can determine whether the scheduled entity performed a type 1 or type 2 channel access procedure for the UL transmission burst. A scheduled entity can use a first type of channel access procedure to initiate a first COT on a communication channel and request a network access node to perform a second type of channel access procedure in a next DL transmission burst. A network access node can receive a message from a scheduled entity, wherein the message comprises a control indication requesting the network access node to perform a first type of channel access procedure in a next DL transmission burst.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for applying a beam switch interruption time across one or more active component carriers. In some cases, a user equipment (UE) may be able to detect a beam switching event and switch, in response to the beam switching event, a beam for communications on a first active component carrier. The UE may apply a beam switch interruption time across one or more second active component carriers if a beam switching delay associated with the beam switch exceeds a threshold value.

Abstract: A scheduling entity can schedule regular or periodic control resources (CORESETs) that are relatively sparse in the time domain compared to dynamic CORESETS. Sparsely scheduled regular CORESETs can reduce the overhead incurred by a user equipment for monitoring the control channels in the CORESETs or search spaces. When the network has a burst of data to send, the scheduling entity can use downlink control information (DCI) piggybacked in physical downlink shared channel (PDSCH) resources to schedule dynamic CORESETs between the regular CORESETs. The dynamic CORESETs can provide resources for a PDSCH and/or physical downlink shared channel (PUSCH).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive scheduling information that schedules a shared channel that is associated with a first beamforming configuration; determine that a gap between the shared channel and a resource associated with a second beamforming configuration fails to satisfy a threshold, wherein the UE is configured to monitor the resource associated with the second beamforming configuration; and modify at least one of the gap to satisfy the threshold or the second beamforming configuration to match the first beamforming configuration based at least in part on determining that the gap fails to satisfy the threshold. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). In some cases, if certain conditions are met, a user equipment (UE) may follow QCL assumptions for a physical downlink shared channel (PDSCH) scheduled by a same PDCCH that indicated the dynamic CORESET. An example method by a UE generally includes receiving at least one downlink control information (DCI), of a first physical downlink control channel (PDCCH), that schedules at least one dynamic CORESET; and receiving a second PDCCH in the dynamic CORESET, wherein the UE is to apply at least one QCL assumption associated with a PDSCH for the at least one dynamic CORESET if one or more conditions are met.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a demodulation reference signal (DMRS) configuration that indicates a code-division multiplexing (CDM) group configured for the UE; receive a first indication of an antenna port, included in the CDM group, assigned to the UE for reception of a first set of DMRS transmissions; receive a second indication of whether a second set of DMRS transmissions for another antenna port, included in the CDM group, is present or absent for another UE; and perform channel estimation based at least in part on the first indication of the antenna port and the second indication of whether the second set of DMRS transmissions for the other antenna port is present or absent. Numerous other aspects are provided.
