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.

Abstract: Some aspects described herein relate to configuring user equipment (UE) for performing sidelink (SL) random access (RA) procedures, which may include assistance from a base station or other network component. One or more parameters for performing a random access procedure with a second UE over a sidelink can be received from a base station. A first random access message can be transmitted to the second UE as part of the random access procedure over the sidelink. A second random access message can be received, from the second UE, in response to transmitting the first random access message, and as part of the random access procedure over the sidelink, where at least one of transmitting the first random access message or receiving the second random access message are based on the one or more parameters.

Abstract: Methods, systems, and devices for sidelink assisted cross-link interference (CLI) determination are described. In some examples, a first wireless device may perform a first measurement of a sidelink message received from a second wireless device. As such, the first wireless device may transmit, to a base station, a report indicating that the second wireless device is estimated to be within a defined proximity of the first wireless device based at least in part on the first measurement satisfying a threshold. In some examples, the first wireless device may receive a control message, from the base station, scheduling transmission of a message between the base station and the first wireless device in a frequency resource in response to the report that the second wireless device is estimated to be within the defined proximity of the first wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a full-duplexing rule that indicates to refrain from using a transmission dropping rule for transmission direction conflicts that occur between uplink and downlink transmissions in a same symbol. The UE may receive a control message scheduling transmission of a message during a symbol, where a transmission direction conflict arises between a first transmission direction of the message and a second transmission direction of the symbol. For example, the UE may identify a transmission direction conflict between an uplink transmission direction of the message and a downlink transmission direction of the symbol. The UE may communicate the message during the symbol based on the full-duplexing rule. The described techniques may enable the UE to attain reduced latency and higher throughput based on reducing a number of transmissions dropped by the UE.
