Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure associated with a component carrier (CC) of a plurality of CCs that are aggregated. The UE may identify, based at least in part on detecting the beam failure, a CC group in which the CC and one or more other CCs, of the plurality of CCs, are included. The UE may transmit, to the BS, a beam failure recovery request (BFRQ) communication associated with the CC group. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, during a multi-slot downlink transmission, that a mapping from a transmission configuration information (TCI) state index to a first TCI state configuration has changed to a second TCI state configuration. The UE may select, based at least in part on the determined change, the first TCI state configuration or the second TCI state configuration to use for at least a portion of the multi-slot downlink transmission. The UE may receive the multi-slot downlink transmission during one or more slots according to the selected TCI state configuration and the TCI state index.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, during a transmission interval, a data transmission over a plurality of beamformed channels and, for each data transmission, a reference signal transmitted in conjunction with the data transmission. The UE may perform, for one or more of the plurality of beamformed channels, a channel state measurement procedure during the transmission interval using the data transmission, the reference signal, or a combination thereof. The UE may transmit, over an acknowledgement/negative acknowledgement (ACK/NACK) signal, a feedback report indicating a result of the channel state measurement procedure for the one or more of the plurality of beamformed channels. The base station may perform, based at least in part on the feedback report, subsequent transmissions to the UE over the one or more beamformed channels.

Abstract: Disclosed are techniques for beam failure recovery in a wireless communications system. In an aspect, a user equipment (UE) detects a beam failure of a first downlink beam received at the UE from a base station, wherein the first downlink beam is a primary downlink beam for a first cell supported by the base station, sends, to the base station, on a supplementary uplink (SUL) beam, a message including an indication of the beam failure and an identification of a second downlink beam to replace the first downlink beam as the primary downlink beam for the first cell, and, based on the base station configuring the second downlink beam as the primary downlink beam for the first cell, establishes an uplink beam for the first cell based on properties of the second downlink beam.

Abstract: The present disclosure relates to transmitting and receiving improved monitoring reports. A base station can configure a user equipment (UE) to monitor a channel/signal on multiple beams. The base station can transmit the multiple beams to the UE, which are at different time periods in a monitoring window. The UE can then monitor the multiple beams within the monitoring window and determine a monitoring report. The UE can then transmit the monitoring report to the base station, wherein the monitoring report indicates a subset of multiple beams as being more or less suitable for communication. The base station can also indicate that it will stop transmitting one or more beams and then stop transmitting the beams. If the UE does not send the report, the base station can continue to transmit the multiple beams.

Abstract: Apparatus, methods, and computer-readable media for facilitating spatial relation indication for uplink control channels and SRS are disclosed herein. An example method for wireless communication at a UE includes determining, based on a rule, a default uplink transmit beam for transmitting an uplink transmission when an uplink transmit beam is not configured by a base station for the uplink transmission. The example method also includes transmitting, to the base station, the uplink transmission on the default uplink transmit beam.

Abstract: A UE detects a beam failure on a first CC. The UE determines whether to transmit a BFRQ to a base station on the first CC or a second CC. The UE determines whether to include a NBI report in the BFRQ. The UE transmits the BFRQ to the base station on the first CC or the second CC. The base station receives a BFRQ from a UE on a first CC or a second CC. The base station determines a new beam for the first CC, where the determination of the new beam is based on a RACH procedure when the BFRQ is received on the first CC or a NBI report in the BFRQ when the BFRQ is received on the second CC. The base station initiates a BFR procedure with the UE for the first CC based on the BFRQ and the new beam determination.
