Abstract: A configuration for configuring and updating the spatial relationship of multiple physical uplink control channel (PUCCH) resources in a single message, thereby reducing signaling overhead. A user equipment (UE) constructs a message associated with at least one of a plurality of component carriers (CCs) or a plurality of bandwidth parts (BWPs) indicating a same spatial relation for the at least one of the plurality of CCs or the plurality of BWPs. The UE transmits the message to a base station. The base station transmits a message to the UE configuring multiple spatial parameters for the at least one of the plurality of CCs, the plurality of BWPs, or a plurality of uplink/downlink resources.

Abstract: Systems, methods, and devices for wireless communication that support resource selection and indication for sidelink demodulation reference signal (DMRS) bundling. A transmitting UE determines sidelink resources for bundling a sidelink DMRS transmission to be transmitted to a receiving UE. In sidelink mode 1, the sidelink resources may be determined based on indications from a base station, which may include whether the transmitting UE is to maintain phase continuity over the sidelink resources during the bundling, or whether the transmitting UE is to include a phase jump reference signal with the bundled DMRS transmission to the receiving UE. In sidelink mode 2, the transmitting UE may select the sidelink resources based on the phase continuity capabilities of the transmitting UE and/or of the receiving UE, and/or based on a sensing of the sidelink channel. In some cases, the receiving UE may provide a resource recommendation to the transmitting UE.

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 that may allow a base station and user equipment (UE) to use uplink transmission configuration indication (TCI) states. An example method generally includes providing, to a network entity, signaling indicating the UE supports uplink Transmission Configuration Indicator (TCI) states indicating one or more quasi co-location (QCL) types for one or more reference signals (RS) to be applied to an uplink transmission, receiving UL TCI after sending the indication, and sending the uplink transmission in accordance with the uplink TCI.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to identify transmission parameters according to a transmission configuration indicator (TCI) state associated with a sounding reference signal (SRS) resource set, a transmission and reception points (TRP) of a network entity, a control resource set (CORESET) pool identifier (ID), or a combination thereof. For example, the network entity may indicate one or more SRS resource set configurations which configure respective a TCI state for one or more SRS resource sets and may indicate the TCI state is associated with a CORESET pool ID. In some cases, UE may identify the TCI state indicated in the activation message, may associate the TCI state with the CORESET pool ID indicated in the activation message, and may identify an SRS resource set configured with a corresponding TCI state.

Abstract: The present disclosure relates to transmitting and receiving improved quality reports using different transmission states. A base station may transmit to a user equipment (UE) a channel comprising multiple beams, wherein the beams include different Transmission Configuration Indicator (TCI) states. The UE can then perform beam quality measurements for the multiple beams. The beam quality measurements can include different channel quality indicator (CQI) measurements and can be performed using the same or different spatial filters. The UE can then determine a combined beam quality report for the different beams and transmit the report to the base station. The beam quality report can also comprise a comparison of, the difference between, or the average of, the different CQI measurements. The UE can also receive a configuration of filtering coefficients from the base station, wherein the beam quality report comprises filtered CQI information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first message activating a plurality of transmission configuration indicator (TCI) states for the UE for uplink communications. The UE may receive a second message that indicates, for uplink communications by the UE, a first TCI state of the plurality of TCI states and that indicates an activation of an uplink beam selection procedure for autonomous selection of an uplink beam by the UE, and may transmit an uplink message using a second TCI state different from the first TCI state, the second TCI state selected by the UE based on the uplink beam selection procedure. In some examples, the UE transmit a request for the activation of the uplink beam selection procedure by the UE.
