Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining when to transmit a beam report indicating a new beam for communicating with a base station after a current beam used for communications with the base station fails. In one example, after detecting beam failure, a user equipment (UE) may compare a quality of each candidate beam available for communicating with a base station to a beam identification threshold, and the UE may perform beam reporting based on the comparisons (e.g., refrain from transmitting a beam report if the quality of each of the candidate beams is lower than the beam identification threshold). In another example, after detecting beam failure, a UE may compare a quality of each candidate beam available for communicating with a base station to a beam detection threshold, and the UE may perform beam reporting based on the comparisons.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node (e.g., a user equipment) may receive, from a second wireless node (e.g., a base station), a downlink signaling message indicating a synchronization signal block (SSB) grouping based at least in part on a full-duplex capability and transmission directions associated with the second wireless node. The first wireless node may configure, and the second wireless node may perform, a beam search and/or a self-interference measurement to identify at least one candidate downlink and uplink beam pair suitable for full-duplex operation based at least in part on the SSB grouping. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A first user equipment (UE) may transmit, to a set of UEs, an indication of a first semi-static traffic pattern between the first UE and a second UE. In some examples, the first semi-static traffic pattern may indicate a pattern for transmission or reception between the first UE and the second UE using a beam pair during a time period. The first UE may receive a response, from one or more UEs, indicating one or more semi-static traffic patterns for the time period. The first UE may then transmit, to a third UE of the one or more UEs, an indication of selection of a second semi-static traffic pattern for communication between the first UE and the third UE during the time period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may receive, from a second WCD, transmission configuration indicator (TCI) state information that defines a set of TCI state configurations for a full duplex operation, wherein TCI state configurations of the set of TCI state configurations are associated with respective receive beams and respective transmit beams. The WCD may transmit, to the second WCD, an indication of one or more candidate TCI states, associated with the set of TCI state configurations, for selection by the second WCD for communications using the full duplex operation. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining when to apply beam updates. A method that may be performed by a user equipment (UE) includes receiving signaling indicating a beam update, determining an application time of the beam update occurs between a downlink control information (DCI) scheduling a transmission and the scheduled transmission, and deciding whether to apply the beam update to the scheduled transmission.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for dynamically updating transmission configuration information (TCI) state and spatial relation information. For example, downlink control information (DCI) or media access control control element (MAC-CE) is used to update a large number of TCI states. As such, high efficiency, such as in terms of low overhead or usage of memory, is achieved with an increase of the upper limit of configured trigger state numbers. The DCI or MAC-CE is used to dynamically update the content in the large number of TCI states.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a message, to a user equipment (UE), instructing the UE to activate or update a reference signal (RS) corresponding to an uplink communication transmitted by the UE. The base station may communicate with the UE, after a time period, using a beam configuration of the base station that corresponds to a beam configuration of the UE for transmitting the RS, the time period being based at least in part on a determination of whether the UE identified the beam configuration of the base station. Numerous other aspects are provided.
