Abstract: Certain aspects of the present disclosure provide techniques for channel state information reference signal (CSI-RS) for multiple beam transmissions. In an example, a first CSI-RS triggering state of one or more CSI-RS triggering states indicates a CSI-RS resource set and associated transmission configuration indication (TCI) states. The CSI-RS resource set includes a plurality of CSI-RS resources. Each CSI-RS resource of the plurality of CSI-RS resources is associated with one or more corresponding TCI states as indicated by the first CSI-RS triggering state. A first CSI-RS resource of the plurality of CSI-RS resources is associated with a first plurality of TCI states as indicated by the first CSI-RS triggering state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of a time domain resource allocation (TDRA), in a unit of a time domain resource block (RB) or in a unit of a time domain RB group, for a communication that is to use a time domain waveform. The unit of the time domain RB or the unit of the time domain RB group may be a sub-symbol unit. The UE may communicate with the base station, using the time domain waveform, based at least in part on the TDRA for the communication. 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 receive, from a base station, search space (SS) configuration information that indicates one or more component carrier (CC) groups and an SS set group configuration for each CC group of the one or more CC groups. The UE may receive, from the base station, a physical downlink control channel (PDCCH) communication on a CC included in a CC group, of the one or more CC groups, where receiving the PDCCH communication is based at least in part on switching between SS set groups, associated with the CC group, on each CC included in the CC group. Numerous other aspects are described.

Abstract: Resource selection for communication of uplink control information may include determining cyclic shift ramping for resource block (RB) sets. A user equipment UE) may use one or more RB sets for transmitting uplink control information on a shared radio frequency spectrum such as an unlicensed band. In some examples, the UE may transmit uplink control information to a base station (BS) via consecutive RB sets. To this end, the BS may schedule consecutive RB sets for an uplink transmission by the wireless communication device and monitor each of these RB sets for uplink control information.

Abstract: An apparatus receives reconfigurable intelligent surface (RIS) information in a sidelink message from a controller of an RIS and transmits the RIS information to a base station. A base station receives RIS information for an RIS and transmits, to the RIS, a message indicating for the RIS to stop transmitting the RIS information. An RIS transmits, via a controller at the RIS, a sidelink message comprising RIS information for the RIS and receives, from a base station, an indication to stop transmitting the RIS information

Abstract: A user equipment (UE) transmits, to a base station, an indication of a capability for physical downlink control channel (PDCCH) monitoring. The UE receives, from the base station, a configuration of a plurality of search space set groups based on the capability. The apparatus then monitors PDCCH candidates for a PDCCH from the base station based on a search space set group and the configuration. A base station receives, from a UE, an indication of a capability for PDCCH monitoring and transmits, to the UE, a configuration of a plurality of search space set groups based on the capability. The apparatus transmits a PDCCH to the UE based on the search space set group and the configuration associated with the search space set group.

Abstract: Wireless communications systems and methods related to multiplexing of synchronization blocks (SSBs), control resource sets (CORESETs), and system information blocks (SIBs) are provided. A user equipment (UE) receives, from a base station (BS), a first SSB of a first group of SSBs of an SSB burst set, wherein the first group of SSBs and a second group of SSBs of the SSB burst set are spaced apart in time by a group of CORESETs and SIBs. The group of CORESETs and SIBs comprises one CORESET and at least one SIB for each SSB of the first group of SSBs. The UE receives, in a first CORESET of the group of CORESETs and SIBs based on the first SSB, SIB scheduling information. The UE receives, based on the SIB scheduling information, a first SIB of the group of CORESETs and SIBs.

Abstract: A base station determines a temporal filter configuration for a user equipment (UE) and transmits the temporal filter configuration to the UE. The temporal filter configuration indicates whether the UE should apply a temporal filter to channel state information (CSI) measurements to generate CSI values, or identifies which temporal filter to apply. The UE generates CSI values based on the temporal filter configuration and reports the generated CSI values to the base station.

Abstract: Apparatus, methods, and computer-readable media for coexistence of multiple uplink control channel formats for wireless communication with power spectral density limitation are disclosed herein. A user equipment (UE) may communicate, with a base station (BS) over a random access channel on a first set of random access resources or a second set of random access resources, a random access request based on a comparison between an intended transmit power of the random access request and a reference transmit power threshold. The UE may communicate, on a first set of uplink resources, a control message for initial network access when the random access request is communicated on the first set of random access resources. The UE also may communicate, on a second set of uplink resources, the control message when the random access request is communicated on the second set of random access resources.

Abstract: Wireless communications systems and methods related to signaling of direct current (DC) locations of user equipment devices (UEs) in a new radio (NR) network are provided. A wireless communication device receives, from a base station, at least one of a carrier aggregation (CA) configuration or a bandwidth part (BWP) configuration. The wireless communication device determines a direct current (DC) location based on at least one of the CA configuration or the BWP configuration. The wireless communication device transmits, to the base station, a report based on the determined DC location. The wireless communication device communicates, with the base station, a phase tracking reference signal (PTRS) configured based on the report.
