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, configuration information indicating a single frequency network (SFN) scheme to be applied by the UE. The UE may receive, from the network node, a transmission configuration indicator (TCI) codepoint indicating two or more TCI states associated with the SFN scheme. The UE may receive, from the network node, a beam indication that is associated with a unified TCI state indication, wherein the beam indication indicates at least one of: updated information for a TCI state, from the two or more TCI states, or that the two or more TCI states are associated with multiple downlink channels. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating model-based uplink-downlink channel tracking are disclosed herein. An example method for wireless communication at a UE includes receiving, from a network node, a model configuration indicative of a model condition of a channel between the UE and the network node. The example method also includes receiving a measurement resource from the network node to measure a condition of the channel. The example method also includes transmitting, to the network node, an SRS. The example method also includes transmitting, to the network node, noise covariance information for the model configuration based on a measurement of the condition of the channel, the noise covariance information associated with the SRS.

Abstract: Wireless communication devices, systems, and methods related to mechanisms for transmitting and receiving reference signals in a high-speed train (HST) single frequency network (SFN). A base station (BS) determines a first frequency pre-compensation value for a reference signal transmitted via a first transmission and reception point (TRP) and a second frequency pre-compensation value for a reference signal via a second TRP. The BS notifies a user equipment (UE) of the first and second pre-compensation values through at least one of the TRPs. The BS applies the first pre-compensation value to the reference signal via the first TRP and the second pre-compensation value to the reference signal via the second TRP. The UE adjusts its tracking loop for the reference signal based on the pre-compensation values, reducing estimation and/or search overhead at the UE.

Abstract: Certain aspects of the present disclosure provide techniques for applying uplink transmission configuration indicator (TCI) states with downlink reference signals to codebook based physical uplink shared channel (PUSCH) transmissions. An example method generally includes receiving, from a network entity, signaling of an uplink transmission configuration indicator (TCI) state with a target codebook based uplink transmission signal, determining if the TCI state has a source downlink reference signal (RS) and deciding how to process the codebook based uplink transmission based on the determination.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration enhancements. A method generally receiving pre-configuration information for one or more reference signal transmissions, performing, at a first time during an ON duration of a discontinuous reception (DRX) cycle, measurements on one or more reference signals based, at least in part, on the pre-configuration information, determining if, at a second time during the ON duration after the first time, a trigger frame associated with the one or more reference signal transmissions has been received, and transmitting a measurement report corresponding to the measurements if a trigger frame has been received.

Abstract: One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method includes determining a configuration of reference signal (RS) resources to be used by a user-equipment (UE) to perform beam measurements, transmitting, to the UE, an indication of the configuration of the RS resources, and receiving, from the UE, a report indicating a plurality of RS resource indicators based on the beam measurements, each of the RS resource indicators being associated with one of the RS resources. In some aspects, the BS selects a subset of the RS resources based on the report from the UE, transmits, to the UE, an indication to provide channel measurement information for the subset of the RS resources, and receives a report including the channel measurement information from the UE. The BS may also perform joint precoding of signals for transmission via the RS resources based on the channel measurement information.

Abstract: A UE detects a beam failure on a first component carrier (CC) that is associated with a secondary cell and transmits a beam failure recovery request (BFRQ) to a base station on a second CC that is associated with a primary cell, the BFRQ indicating whether new beam information (NBI) for the first CC is included in the BFRQ.
