Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a UE-requested BFD/BFR reference signal. In aspects, the UE may transmit, to a base station, a request for a list of a set of beams for BFD and a list of a set of candidate beams for BFR. The UE may receive, from the base station based on the transmitted request, information indicating the set of beams for BFD and the set of candidate beams for BFR.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, a scheduling downlink control information (DCI) communication that schedules a physical downlink shared channel (PDSCH) transmission, the scheduling DCI including an indication of a resource allocation for a DCI communication, wherein the resource allocation for the DCI communication includes one or more resources included in a resource allocation for the PDSCH transmission, and receive the PDSCH transmission that includes the DCI communication based at least in part on the indication of the resource allocation for the DCI communication. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to configuring the structures of synchronization signal blocks (SSBs) and SSB burst sets in scenarios where two or more different types of SSB burst sets may be utilized in a wireless communication system (e.g., SSB burst sets including SSBs having different subcarrier spacing (SCS)). The SSB burst sets may be configured to include different components in an SSB (e.g., one or more of primary and second synchronization signals and a physical broadcast channel), include resource allocation information, include a physical-layer cell identity (PCID) configuration for a first SSB burst set that may be used to determine a PCID for a second SSB burst set, and enable quasi co-locating SSBs in a first SSB burst set with a second SSB burst set.

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 (UE) may receive a multi-slot grant for one of uplink communication or downlink communication. The UE may communicate in the multi-slot grant based at least in part on information that provides an indication of one or more time gaps for the multi-slot grant. 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: Certain aspects of the present disclosure provide techniques for transmitting channel state information reference signals (CSI-RS) scheduled by a remaining minimum system information (RMSI) physical downlink control channel (PDCCH) for use by a user equipment (UE) for beam refinement. A method by a user equipment (UE) includes receiving a physical downlink control channel (PDCCH), from a base station (BS), that schedules transmission of a remaining minimum system information (RMSI) and schedules transmission of a channel state information (CSI) reference signal (CSI-RS) by the BS; and processing the CSI-RS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a flag is enabled or is disabled, the flag indicating whether channel state information (CSI) associated with a secondary discontinuous reception (DRX) group is permitted to be transmitted outside of an active time associated with a primary DRX group. The UE may selectively transmit the CSI associated with the secondary DRX group in an uplink communication associated with the primary DRX group based at least in part on whether the flag is enabled or is disabled. Numerous other aspects are provided.

Abstract: A non-terrestrial network is provided that includes a satellite that transmits an orbital parameter message to a user equipment. The user equipment processes the orbital parameter message to determine a current range from the user equipment to the satellite based upon the received orbital parameter message, a timing offset and a frequency offset for an uplink transmission to the satellite.
