Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for using different configurations for downlink or uplink transmissions associated with different transmission configuration indication (TCI) states (e.g., transmitted on different beams). In one example, a base station may use different configurations for downlink transmissions to a user equipment (UE), and the base station may indicate the different configurations to the UE. For instance, the base station may transmit downlink control information (DCI) indicating a baseline configuration and other configurations as a delta of the baseline configuration. In another example, a base station may dynamically indicate a timing advance to a UE (e.g., in DCI or flow control feedback) for an uplink transmission from the UE associated with a TCI state, and the UE may use the dynamically indicated timing advance for uplink transmissions associated with the TCI state.

Aspects may include a base station coordinating a first UE and a second UE establishing relay link for directly communicating with one and other. In some cases, the relay link may be a beamformed relay link and the base station and one of the UEs may use to the relay link to communicate if a direct communication link between the base station and the UE fails. The base station may transmit reference signal information to the first and second UE for establishing a relay link. The first and second UE may perform one or more relay link beam sweeping procedures based on the reference signal information and establish the relay link based on the beam sweep procedures. In some cases, coordinating the relay link may be based on one of the UEs transmitting a triggering message to the base station.

The UE may further transmit to another UE, on a sidelink, the sidelink communication parameter and the attribute. The UE may also communicate with the other UE on the sidelink based on the transmitted sidelink communication parameter and the attribute.

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.

A first user equipment (UE) (e.g., “victim” UE) may receive control signaling indicating a cross-link interference (CLI) reporting configuration associated with a set of CLI resources, where the CLI resources are associated with varying levels of CLI at the first UE. The first UE may perform CLI measurements on signals received from a second UE (e.g., “aggressor” UE) within the set of CLI interference resources based on the CLI reporting configuration. The first UE may then transmit, based on the CLI measurements, a CLI report identifying a CLI resource from the set of CLI resources, wherein the CLI resource is associated with a CLI measurement that fails to satisfy a CLI threshold, or wherein the CLI resource is associated with a lower level of CLI as compared to other CLI resources within the set of CLI resources.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for signaling whether to generate cross-link interference (CLI) measurement reports based on a single CLI measurement occasion or based on multiple CLI measurement occasions. A network entity may indicate whether to generate a CLI measurement report based on a single most recent CLI measurement occasion or based on CLI measured over a number of CLI measurement occasions. The measuring user equipment (UE) may generate a CLI report based on a single most recent CLI measurement occasion or based on a statistical CLI measurement based on respective CLI measurements for each respective CLI measurement occasion of the number of CLI measurement occasions depending on the indication. The network entity may also indicate to the aggressor UE to repeat transmission of sounding reference signals using the same transmit beam during the CLI measurement occasions.

In some cases, a UE may be configured to communicate with multiple transmission and reception points (TRPs). The TCI state to apply to the CLI measurement may be based on the TRP scheduling the CLI measurement.
