Abstract: Certain aspects of the present disclosure provide techniques for a partially network-controlled repeater. A method for wireless communications by a repeater includes receiving downlink control information (DCI) from a network entity via a backhaul link, the DCI indicating a time period for beam management. The method includes performing a beam management procedure with a user equipment (UE) during the time period. The method includes determining a beam for communicating with the UE based on the beam management procedure. The method includes communicating with the UE using the beam.

Abstract: Certain aspects of the present disclosure provide techniques for differential measurement reporting for lower-layer triggered mobility (LTM). An example method, performed at a wireless node, generally includes measuring reference signals (RSs), wherein each of the RSs is associated with a cell and a beam, generating, based on the measuring, a report that indicates RS measurements associated with different cells, wherein the report indicates: one or more absolute values of one or more of the RS measurements and one or more differential values for other RS measurements, wherein each of the differential values represents a difference in value of one of the other RS measurements relative to one of the one or more absolute values, and outputting the report for transmission.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a user equipment (UE) to communicate with a network entity based on a selected antenna panel reported to a network entity. An example method generally includes transmitting, to a network entity, a report including information associated with an antenna panel selected for communications between the user equipment and the network entity; selecting a starting time and a wait time to apply a configuration associated with the selected antenna panel; activating an update timer based on the starting time and the wait time; and communicating with the network entity based on the configuration associated with the selected antenna panel after expiry of the update timer.

Abstract: A configuration to configure a UE to activate a subset of configured UL-TCI states. The apparatus receives a configuration of UL-TCI states and an activation of a subset of configured UL-TCI states. The apparatus receives DCI in a PDCCH scheduling an UL transmission with one or more TCI states of activated TCI states. The apparatus transmits the UL transmission based on the one or more TCI states.

Abstract: Certain aspects of the present disclosure provide techniques that may allow a base station and user equipment (UE) to use uplink transmission configuration indication (TCI) states. An example method generally includes providing, to a network entity, signaling indicating the UE supports uplink Transmission Configuration Indicator (TCI) states indicating one or more quasi co-location (QCL) types for one or more reference signals (RS) to be applied to an uplink transmission, receiving UL TCI after sending the indication, and sending the uplink transmission in accordance with the uplink TCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a capability value set list identifying one or more capability sets. The UE may transmit, to the base station, a channel state information (CSI) report that includes a capability set identifier identifying a capability set of the one or more capability sets of the capability value set list. The UE may receive a feedback message indicating whether the base station successfully received the CSI report and whether to retransmit information identifying the capability set identifier. Numerous other aspects are described.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: Aspects of the disclosure are directed to a user equipment (UE) configured for detecting phase coherence failure in coherent joint transmissions (CJTs) from multiple wireless nodes (e.g., transmission/reception points (TRPs) and/or base stations). In some examples, the UE is configured to obtain signaling from a plurality of wireless nodes, the signaling including a first signal from a first wireless node of the plurality of wireless nodes and a second signal from a second wireless node of the plurality of wireless nodes. The UE is also configured to estimate a phase difference between the first signal and the second signal. In some examples, the UE is configured to output, for transmission to at least one of the first wireless node or the second wireless node, an indication of the estimated phase difference.

Abstract: An apparatus is provided that may be configured to transmit, to a base station having multiple TRPs, a CSI report based on a set of reference signals, the set of reference signals including a first reference signal associated with a first beam direction and a second reference signal associated with a second beam direction. The apparatus may further be configured to switch, for one or more channels, to use the first beam direction with a first TRP of the multiple TRPs before an indication to switch beams is received from the base station.
