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 cell of a plurality of cells. The UE may selectively transmit a beam failure recovery request (BFRQ) communication for the cell based at least in part on a determination of whether a threshold time period has elapsed since a previous BFRQ communication was transmitted for the cell or another cell of the plurality of cells. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may support communications with a set of transmission/reception points (TRPs). The UE may receive one or more signals from at least one TRP of the set of TRPs. The one or more signals may indicate a condition corresponding to the UE for the multi-TRP communications. The UE may determine the condition of the UE based on the one or more signals. The UE may communicate with one or more TRPs of the set of TRPs based on the one or more signals. For example, the UE may communicate with the one or more TRPs according to a multi-TRP communications configuration determined based on the condition of the UE.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes performing beam failure detection (BFD) of a beam pair link (BPL) associated with a secondary cell (Scell) of a base station (BS), sending a beam failure recovery request (BFRQ) message in another cell of the BS, the BFRQ message including an indication of a candidate recovery beam for the Scell, and starting a timer based on sending the BFRQ.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a first downlink grant (e.g., a PDCCH transmission) for a first data transmission (e.g., a PDSCH transmission) over a first component carrier; the first data transmission over a second component carrier; and a second downlink grant (e.g., another PDCCH transmission) for a second data transmission (e.g., another PDSCH transmission) over the second component carrier. A user equipment (UE) receives the first data transmission over a first beam and may use the first beam for receiving the second data transmission. Additionally or alternatively, the UE may receive a configuration message indicating a set of TCI states for downlink data transmissions to the UE; identify one or more reference signals monitor for beam failure detection (BFD), identify one or more BFD beams, monitor the identified one or more reference signals; and selectively trigger a beam failure reporting procedure.

Abstract: The present disclosure relates to apparatus and methods of signal to interference and noise ratio (SINR)-based group beam reporting. In particular, this disclosure relates to measurement report configurations for initiating a protocol layer 1 (L1)-SINR based group beam report, and corresponding measurement resource transmissions by a base station and measurement and reporting actions of the UE to report the L1-SINR for each of at least two beams that can be simultaneously received. The measurement report configurations include a channel measurement resource (CMR) configuration, an interference measurement resource (IMR) configuration, or both. The measurement configuration may indicate a plurality of CMR repetition sets, or N resource sets of 1 CMR resource plus N−1 IMRs, e.g., 1 CMR mapped to N−1 IMRs, or N×(N−1) resource sets of a CMR and an IMR, e.g., 1 CMR mapped to 1 IMR, where N is the number of candidate Tx beams.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a list of transmission configuration indicator (TCI) state patterns where each entry in the list may correspond to a different TCI state pattern. The base station may transmit an indication of a selected entry from the TCI state pattern list and transmit a grant to the UE indicating that resources have been allocated in for transmitting a transport block (TB). The UE may receive the grant and attempt to receive the TB in accordance with the indicated TCI state pattern. The UE may generate multi-bit feedback to indicate whether the UE was able to successfully decode the TB and transmit the feedback to the base station. The base station may use the multi-bit feedback for determining whether to select a different TCI state pattern.

Abstract: A configuration to configure a UE to activate a subset of configured SRS trigger states. The apparatus receives a configuration activating a subset of configured SRS trigger states. The apparatus receives DCI in a PDCCH triggering an aperiodic SRS transmission based on one or more SRS trigger states of activated SRS trigger states. The apparatus determines an aperiodic SRS resource set based on the configuration and the DCI indicating the one or more SRS trigger states. The apparatus transmits aperiodic SRS within the aperiodic SRS resource set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a beam failure recovery scheduling request (BFR-SR) to a primary cell or a primary secondary cell base station based at least in part on detecting a beam failure associated with a secondary cell (SCell) link between the UE and an SCell base station. The UE may start a timer based at least in part on transmitting the BFR-SR. The UE may retransmit the BFR-SR based at least in part on the timer expiring prior to the UE receiving a response to acknowledge the BFR-SR and schedule transmission of a medium access control (MAC) control element (MAC-CE) including information to recover from the beam failure and/or the timer expiring prior to the UE transmitting the MAC-CE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a control resource set (CORESET) is not configured for an active downlink bandwidth part of a component carrier (CC) of the UE. The UE may determine that a transmission configuration indication (TCI) state is not activated for a physical downlink shared channel (PDSCH) of the active downlink bandwidth part of the CC. The UE may determine a default spatial relation for an uplink control channel or uplink signal for the CC based at least in part on determining that the CORESET is not configured for the active downlink bandwidth part of the CC and that the TCI state is not activated for the PDSCH of the active downlink bandwidth part of the CC. Numerous other aspects are provided.
