    Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) may receive an indication of a set of channel measurement resources (CMRs) that are configured for a group-based reference signal measurement for multiple transmission and reception points (TRPs). The UE may identify or determine whether a set of one or more directional beams used by the UE to measure reference signal transmissions from each of the multiple TRPs satisfy a threshold directivity gain. The UE may transmit a request to enable a scheduling restriction at the UE for a time period associated with the group-based reference signal measurement if the set of directional beams fail to satisfy the threshold directivity gain and may transmit a request to disable the scheduling restriction if the set of directional beams satisfy the threshold directivity gain.

    Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device, which may be an example of a user equipment and/or a base station, may receive a signal from a receiving device indicating an antenna topology supported by the receiving device. The transmitting device may select, based at least in part on the antenna topology, a diversity scheme for performing a wireless transmission to the receiving device, the diversity scheme including one or more diversity types from a plurality of diversity types. The transmitting device may transmit the wireless transmission to the receiving device employing the selected diversity scheme.

    Abstract: A user equipment (UE) may transmit, to a primary cell, an indication of a capability to synchronize with a secondary cell based on measurements of the primary cell. A UE may estimate a propagation delay (tp) and an angle of arrival (AoA) of the secondary cell based on a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) transmitted by the primary cell. A UE may perform automatic gain control (AGC), fine timing synchronization, and fine frequency synchronization of the secondary cell based on a temporary aperiodic tracking reference signal (A-TRS) transmitted by the secondary cell. A UE may perform a receive beam sweep on a burst of a CSI-RS transmitted by the secondary cell, wherein a range of the receive beam sweep is based on the estimated AoA.

    Abstract: A method for wireless communication includes a first wireless communication device receiving, from a second wireless communication device, one or more signals for each of a plurality of candidate sensing beams and a transmission beam. The method also includes determining, for each of the plurality of candidate sensing beams based on at least one of the one or more signals for the respective candidate sensing beam, a first signal measurement. The method also includes determining, based on at least one of the one or more signals for the transmission beam, a second signal measurement with respect to a direction of the transmission beam, and determining, for each of the plurality of candidate sensing beams based on the respective first signal measurement and the second signal measurement, beam coverage information with respect to the transmission beam direction.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine an emissions mask (e.g., an in-band emission (IBE) mask) for a user equipment (UE) which may be determined based on the total number of UEs scheduled by the base station for uplink transmissions during a same transmission time interval (TTI). The base station may transmit downlink control information (DCI) to the UE indicating the emissions mask. The base station may additionally transmit a grant to the UE allocating resources for the UE based on the UE's position relative to other UEs served by the base station. The UE may receive the DCI and may map the emissions mask to a maximum power reduction (MPR). Based on the MPR, the UE may determine a transmit power and may transmit an uplink transmission to the base station according to the transmission power and the DCI.
