Abstract: Apparatus, methods, and computer-readable media for facilitating beam management enhancements in model-based channel tracking are disclosed herein. An example method for wireless communication at a first network entity includes receiving from a second network entity, a model configuration indicative of a model condition of a channel between the first network entity and the second network entity for multiple beam pairs. The example method also includes tracking a variation in a channel condition relative to the model condition of the channel based on the model configuration for each of multiple beam pairs separately in multiple tracking sessions that overlap in time. Each beam pair may include a transmission beam and a reception beam.

Abstract: Certain aspects of the present disclosure provide techniques for precoding for multi-panel uplink transmission. For codebook-based uplink transmission, a user equipment (UE) can determine one or more preferred or selected precoders for uplink transmission. The precoders can be from an expanded UE codebook that maps a first number of transmit layers at the UE to a second number of antenna ports at the UE, the layers and/or antenna ports associated with multiple uplink transmit panels at the UE. The UE sends an indication to a base station (BS) of the determined precoders and/or sends an uplink transmission using the determined precoders. For non-codebook based uplink transmission the UE receives first and second reference signals (RSs), from first and second ports of a BS, with first and second UE antenna panels. The UE computes precoders to use for uplink transmission based on the RSs.

Abstract: Certain aspects of the present disclosure provide techniques for control channel resource grouping and spatial relation configuration. Aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes receiving an indication of one or more groupings of one or more control channel resources within a configured bandwidth. Each grouping is associated with a spatial relation. The UE applies a spatial relation for a control channel transmission using one or more control channel resources in a grouping of the one or more groupings. The grouping is associated with the spatial relation.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (LIE) may select uplink communication resources to be used to transmit enhanced uplink control information (UCI) to a base station based at least in part on a size of a hybrid automatic repeat request (HARQ) codebook and an enhancement number, and transmit the enhanced UCI using the selected uplink communication resources, the enhanced UCI comprising a set of feedback bits and a set of enhancement bits, the set of feedback bits comprising at least one negative acknowledgement (NACK) bit, and wherein the set of enhancement hits indicate information associated with the at least one NACK bit. 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 receive information identifying a transmission configuration indicator (TCI) state, wherein the TCI state identifies an association between a periodic demodulation reference signal (DMRS) and a target reference signal. The UE may communicate the periodic DMRS identified by the TCI state. The UE may transmit or receive the target reference signal based at least in part on the periodic DMRS and the TCI state. Numerous other aspects are provided.

Abstract: Certain aspects provide enhancements to enable per transmission reception point (per-TRP) based beam failure recovery (BFR), and more particularly, techniques for configuring physical uplink control channel (PUCCH) BFR for TRP specific BFR. A method that may be performed by a user equipment (UE) includes communicating with at least two TRPs using beams associated with at least two beam groups, each of the beams groups associated with one of the TRPs, detecting a beam failure in a beam group of the at least two beam groups, transmitting a beam group specific BFR scheduling request (SR), in accordance with one or more rules, for an uplink (UL) grant to transmit a beam failure recovery request (BFRQ) specific to the beam group in which the beam failure was detected, receiving the UL grant in response to the SR, and transmitting the BFRQ specific to the beam group based on the UL grant.

Abstract: Aspects relate to configuration for channel state information (CSI) signaling. For example, a base station may transmit, to a user equipment (UE), a configuration message indicating report metrics, where each of the report metrics is associated with at least one corresponding CSI resource set of CSI resource sets associated with antenna panels configured for communication with the UE. The base station may further transmit at least one reference signal via at least one of the antenna panels to the UE in accordance with the configuration message. The base station may further receive, from the UE, a CSI report that includes report quantity values respectively associated with the report metrics, where the report quantity values are based on measurement of the at least one reference signal according to the configuration message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a tracking reference signal (TRS) pattern to be used for receiving a TRS. The TRS pattern may indicate a plurality of TRS symbols of the TRS, one or more TRS symbols of the plurality of TRS symbols having a bandwidth that is different than a bandwidth of at least one other TRS symbol of the plurality of TRS symbols, or having a discontinuous tone allocation. The UE may receive the TRS based at least in part on the TRS pattern. Numerous other aspects are provided.
