Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to switch a beam used by the UE, wherein the indication triggers at least one of a reference signal for a beam measurement or a transmission of a measurement report, based at least in part on an association of the beam with the reference signal or the measurement report. The UE may receive the reference signal associated with the beam measurement based at least in part on receiving the indication to switch the beam. The UE may transmit, using one or more transmission parameters, the measurement report indicating a measurement of the reference signal, wherein the one or more transmission parameters are based at least in part on receiving the indication to switch the beam. Numerous other aspects are described.

Abstract: A configuration for inter-cell interference coordination in wireless communication systems. The apparatus determines a priority order of a first base station to schedule a first transmission with a first UE. The apparatus transmits a first transmission request to the first UE to schedule the first transmission. The apparatus receives, from the first UE, a measurement report based on the first transmission request received by the first UE, the measurement report indicates a signal quality of the first transmission request. The apparatus determines to schedule the first transmission with the first UE based at least on the measurement report. The apparatus sends a schedule indication to at least a second base station indicating whether the first transmission is scheduled with the first UE, at least the second base station has a lower priority order than the first base station.

Abstract: Wireless communications systems and methods can use common transmission configuration indication (TCI) states to indicate beam directions for single-target and multi-target communications. A wireless communication device is configured to communicate a configuration for a plurality of transmission configuration indications (TCIs). The wireless communication device is further configured to communicate a first activation of a first TCI of the plurality of TCIs for a first signal, and a second activation of a second TCI of the plurality of TCIs for a plurality of second signals. The wireless communication device is further configured to communicate, based on the first TCI, the first signal, and communicate, based on the second TCI, at least one of the plurality of second signals.

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 set of reference signal resources, wherein the set of reference signal resources is associated with two or more subbands included in a band used for communication between the UE and the base station. The UE may receive, based at least in part on one or more resources of the set of reference signal resources, at least one reference signal over the band. The UE may derive one or more measurements, associated with one subband of the two or more subbands, based at least in part on the at least one reference signal received over the band. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer program products for per beam group BFR RS are provided. An example method includes receiving, from a base station, a per beam group beam failure recovery (BFR) configuration comprising one or more beam failure detection (BFD) reference signal (RS) per beam group based on one or more of: a maximum number of BFD RS sets supported by the UE, a maximum number of BFD RS per set that is supported by the UE, or a maximum number of total BFD RS across each set that is supported by the UE. The example method measuring reference signal received power (RSRP) of the one or more BFD RS at a beam group based on the per beam group BFR configuration for a TRP.
