Abstract: Methods, systems, and devices for wireless communications are described. A first device may monitor for a set of reference signals from a second device using a set of directional beams. The first device may perform measurements on the received reference signals and select a subset of directional beams from the set of directional beams based on the performed measurements. Each directional beam may be associated with a set of beamforming weights. The first device may communicate with the second device using a dynamic set of beamforming weights. The first device may form the dynamic set of beamforming weights using a combination of beamforming weights from each set of beamforming weights associated with the subset of directional beams. The dynamic set of beamforming weights may be different from each set of beamforming weights associated with the subset of directional beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a change of one or more reception conditions. The UE may transmit, to a base station and based at least in part on the change of the one or more reception conditions, a request for a radio link adaptation operation to update one or more of a reception beam or a transmission beam of the base station used to communicate with the UE. Numerous other aspects are described.

Abstract: In an aspect, a user equipment (UE) transmits, to a base station, an uplink (UL) power change capability indication. The base station receives the UL power change capability indication, and transmits, to the UE, scheduling information for one or more UL transmissions that include one or more UL power changes based on the UL power change capability indication.

Abstract: Methods, systems, and devices for wireless communications are described that provide for antenna selection at a user equipment (UE). The UE may have a set of available antennas for uplink and downlink communications, and may select a first subset of antennas for uplink communications and a second subset of antennas for downlink communications. The first subset of antennas may be based on one or more uplink metrics, and the second subset of antennas may be based on the first subset of antennas and one or more downlink channel metrics, traffic amounts, or any combinations thereof.

Abstract: Aspects of the disclosure relate to devices, systems and methods for multi-beam formation. A user equipment (UE) may determine a sampling interval for references signals to be transmitted by a base station for an upcoming control or data communication. For example, the UE may determine a maximum sampling interval tolerable for channel estimation and select the sampling interval based on the maximum. In some examples, the UE determines the sampling interval based on characteristics of its motion. The UE transmits an indication of the sampling interval to the base station. Based on the indication, the base station selects an interval for the reference signals and transmits the reference signals to the UE to enable it to perform the channel estimation for the multi-beam. The base station may determine to select the interval for the reference signals such that it is less than or equal to the sampling interval indicated by the UE.

Abstract: Certain aspects of the present disclosure provide techniques for reducing a quantity of antenna elements for uplink transmission. A method that may be performed by a user equipment (UE) includes determining a virtual power headroom (VPHR) associated with uplink transmission for each of a plurality of beams, selecting one or more beams of the plurality of beams for the uplink transmission based on the determination such that the VPHR associated with each of the one or more beams is at least equal to or greater than zero, and indicating a parameter associated with the one or more beams for selection of a beam to be used for the uplink transmission.

Abstract: Various aspects of the present disclosure generally relate to systems, apparatuses, and methods for beam determination prior to an indication of an activated beam. A user equipment may receive a configuration for one or more transmission configuration indicator (TCI) states; receive downlink control information that schedules a downlink transmission after a time offset; determine, prior to receiving an indication of an activated TCI state of the one or more TCI states, a beam for receiving the downlink transmission; and receive the downlink transmission using the beam. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a user equipment (UE) indication of a capability of the UE for the supported number trigger states. A method that may be performed by the UE includes providing an indication to a base station (BS) of a maximum number of aperiodic trigger states supported by the UE. The UE receives a configuration or activation of aperiodic trigger states from the BS in accordance with the indication. A method that may be performed by a BS includes receiving the indication from the UE and providing a configuration or activation of aperiodic trigger states to the UE in accordance with the indication.
