Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to cell recovery techniques. One example method generally includes receiving, on a first cell, an indication that one or more channel measurements are to be reported for a second cell for which beam failure is detected; transmitting a first message triggering reporting of at least one preferred beam for communicating on the second cell, the first cell being different from the second cell, wherein the first message is transmitted in response to the indication that the one or more channel measurements are to be reported; receiving a report indicating the at least one preferred beam; and configuring a transmission configuration state in accordance with the at least one preferred beam for communicating on the second cell.

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: Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) may transmit, to a second UE, first control information indicating a first transmission configuration indicator (TCI) state for use in sidelink communications between the first UE and the second UE. The first UE may receive, from the second UE, second control information indicating a second TCI state for use in sidelink communications between the first UE and the second UE, where a first application time of the first TCI state conflicts with a second application time of the second TCI state. The first UE may select, in accordance with one or more rules for resolving sidelink TCI state conflicts, one of the first TCI state or the second TCI state as a selected TCI state. Accordingly, the first UE may communicate with the second UE in accordance with the selected TCI state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) reporting configuration for a CSI report, wherein the CSI reporting configuration indicates that the CSI report is to include a layer 1 signal to interference plus noise ratio (L1-SINR). The UE may determine a number of CSI processing units (CPUs) occupied for processing of the CSI report that is to include the L1-SINR. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a first slot-related channel sensing procedure to perform during channel sensing. The first slot-related channel sensing procedure may be one of multiple available slot-related channel sensing procedures. The first slot-related channel sensing procedure may indicate time interval increments in which to perform the channel sensing. The UE may perform the first slot-related channel sensing procedure based on the indication. The UE may perform the first slot-related channel sensing procedure in the time interval increments of a sidelink resource pool to identify a first time-frequency resource of the sidelink resource pool that is available for transmission of a sidelink message.

Abstract: This disclosure relates to the set-up, activation, and deactivation of sidelink carrier aggregation, and includes a method and apparatus for transmitting or receiving a reference signal to a second UE on a designated sidelink component carrier as part of an initial beam scanning procedure; receiving a configuration message from a network entity indicating one or more additional sidelink component carriers for the first UE and the second UE; and communicating with the second UE via a sidelink corresponding to at least one of the one or more additional sidelink component carriers or the designated sidelink component carrier based on the configuration message on a sidelink beam pairing performed in the designated sidelink component carrier, wherein the first UE and the second UE are configured in coverage with the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive an indication of first resources from a second UE. In some examples, the second UE may be a UE configured to receive a transmission from a third UE over the first resources. In some such examples, the first UE may transmit, to a fourth UE, a sidelink transmission over available resources that exclude the first resources. Additionally, or alternatively, the second UE may be a UE that received sidelink control information from the third UE indicating the resources for transmission by the third UE to a fourth UE. In some such examples, the first UE may transmit, to the second UE, a sidelink transmission over available resources that exclude the first resources.

Abstract: A method of wireless communication, by a first sidelink user equipment (UE), includes periodically receiving a set of sidelink beam failure detection reference signals (RSs) from a second sidelink UE. The method includes incrementing a beam failure detection (BFD) counter in response to one or more reference signals of the set of sidelink beam failure detection RSs having a received signal strength below a threshold. The first sidelink UE starts a beam failure detection timer in response to the reference signal(s) of the set of sidelink beam failure detection reference signals having the received signal strength below the threshold. Another method by a sidelink UE may periodically transmit a set of sidelink BFD RSs to another sidelink UE. The set of sidelink BFD RSs comprise one or more sidelink receive RSs. The sidelink UE configures the other sidelink UE with the sidelink receive BFD RSs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a first resource, of a plurality of resources, for transmission of a request to initiate a beam failure recovery procedure. The UE may determine that another transmission is scheduled contemporaneously with the transmission of the request to initiate the beam failure recovery procedure using the first resource and is to be transmitted using the first resource. The UE may select a second resource for transmission of the request to initiate the beam failure recovery procedure based at least in part on the determination that the other transmission is scheduled contemporaneously with the transmission of the request to initiate the beam failure recovery procedure and is to be transmitted using the first resource. Numerous other aspects are provided.
