Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive a control message that triggers reception of CLI reference signals for CLI measurements. The first UE may adjust a reception timing of the first UE for the CLI measurements. The first UE may adjust the reception timing during a time interval that occurs after the control message is received and in accordance with a rule to align the reception timing of the first UE with a transmission timing of a second UE. The transmission timing of the second UE may be associated with transmission of the CLI reference signals from the second UE. The first UE may perform the CLI measurements using the adjusted reception timing in accordance with the rule. The first UE may transmit a report to the network entity that indicates one or more CLI metrics corresponding to the CLI measurements.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a user equipment (UE) to receive a message including transmission configuration indicator (TCI) states information associated with beam information for uplink or downlink resources. The UE may identify multiple channels or reference signals, or both, to which a TCI state is to be applied based on associated indications included with the TCI state information. In some examples, the TCI state information may also include indications of source reference signals for quasi co-location (QCL) assumptions for the indicated channels or reference signals. Based on applying the TCI state, the UE may determine beam information for uplink or downlink resources and may communicate with the base station accordingly.

Abstract: Certain aspects of the present disclosure provide techniques for beam indication set reuse. A method for a wireless communication that may be performed by a user equipment (UE) includes receiving signaling configuring the UE with a beam indication set. The method includes receiving an indication to apply the configured beam indication set to multiple bandwidth parts (BWPs) and/or multiple component carriers (CCs). The method includes applying the beam indication set to a BWP or CC based on the indication. The beam indication set may be for uplink or downlink communications. The beam indication set may be a transmission configuration indicator (TCI) state set or spatial relation set. Other aspects and features are also claimed and described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for beam refinement via physical random access channel (PRACH) repetition. A method that may be performed by a network entity includes determining resources to monitor for a PRACH transmission sent from a user equipment (UE) as part of a random access channel (RACH) procedure, performing receive beam sweeping when receiving PRACH repetitions sent using the determined resources, using results of the receive beam sweeping to refine one or more beams and to select a refined beam of the refined one or more beams, and using the selected refined beam for at least one of receiving a subsequent message from the UE as part of the RACH procedure or sending a subsequent message to the UE as part of the RACH procedure.

Abstract: Techniques for wireless communications are described. A first device may communicate with a second device using a first beam. Based on communicating with the second device, the first device may indicate a reference signal associated with a different beam to indicate that the different beam associated with the reference signal is preferred for subsequent communications. The reporting device may switch to the different beam based on transmitting the indication of the reference signal. Based on switching to the different beam, the reporting device may determine a communication parameter based on the indicated reference signal and communicate with the scheduling device using the second beam based on the determined communication parameter.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a plurality of random access occasions for uplink message transmission to a base station. The UE may determine that a first portion of the plurality of random access occasions is unavailable for use by the UE as a result of the base station operating in a full duplex mode. The UE may select one or more random access occasions from a second portion of the plurality of random access occasions instead of from the first portion based at least in part on the determining. The UE may transmit a random access message to the base station during the one or more random access occasions from the second portion.
