    Abstract: Certain aspects of the present disclosure provide a method of wireless communication at a user equipment (UE), generally including outputting, for transmission, a first channel prediction report based on measurements of first reference signals (RS) associated with a first beam; outputting, for transmission, a beam prediction report indicating a second beam; outputting, for transmission before a predicted application time for the second beam, a second channel prediction report based on measurements of second RS associated with the second beam, said second channel prediction report indicating a precoder; and obtaining a beamformed transmission based on the second beam and the precoder.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a configuration for applying weighted averaging to layer 1 (L1) reference signal received power (RSRP) measurements. The UE may receive, from the network node, a plurality of reference signals during a period of time, the plurality of reference signals being quasi-co-located with each other. The UE may obtain weighted averaged L1 RSRP measurements associated with the plurality of reference signals based at least in part on the configuration, the weighted averaged L1 RSRP measurements being available as input to a machine learning (ML) model for beam prediction. Numerous other aspects are described.

    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 beam report that indicates that the UE is to switch to a beam for a physical uplink channel. The UE may switch to the beam a specified time offset after one of: transmitting the beam report to the base station, receiving a beam switch response from the base station in response to the beam report, or a scheduled communication on the physical uplink channel. Numerous other aspects are described.

    Abstract: Aspects relate to measuring and scheduling reference signals. A user equipment (UE) detects reference signals having overlapping resources, and determines a context associated with the reference signals. A Layer 1 (L1) measurement is then performed of at least one reference signal according to a prioritization associated with the context. In another aspect, a network entity determines a scheduling of resources that enables a UE to prioritize performing an L1 measurement of a reference signal from a non-serving cell, and communicates with the UE according to the scheduling. In yet another aspect, a UE communicates with a gNb using transmission configuration indication (TCI) states associated with a corresponding control resource set (CORESET) pool of CORESETs. Beam failure detection (BFD) reference signals are then identified explicitly via a configuration signaling, or implicitly based on the TCI states. The BFD reference signals are then monitored to facilitate detecting a beam failure event.

    Abstract: In a unified transmission configuration indicator (TCI) framework, certain channels are preconfigured to use a fixed number of TCI states. However, these preconfigured channels are not currently updated when the number of TCI states dynamically change during a switch between single and multiple transmission and reception point (TRP) modes. To alleviate this problem, a user equipment (UE) may receive downlink control information (DCI) indicating a first number of TCI states and, prior to the DCI, downlink information indicating a second number of TCI states, detect a switch between the multiple TRP (mTRP) and single TRP (sTRP) modes based on the first number of TCI states being different than the second number of TCI states, and communicate in a channel configured to use a selected TCI state associated with the first number of TCI states using a predefined rule based on the switch between the mTRP and sTRP modes.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node on a beamformed link from the first node to the second node, a first signal, wherein the first node and the second node are associated with common timing; determine whether a second signal, based at least in part on the first signal, is received on a beamformed link from the second node to the first node; and transmit a third signal based at least in part on receiving the second signal or perform a sidelink beam failure recovery procedure based at least in part on determining that the second signal is not received. Numerous other aspects are provided.
