Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node (e.g., a user equipment) may determine one or more measurements associated with a beam search performed during a downlink beam management process. The first wireless node may transmit, to a second wireless node (e.g., a base station), a report that indicates one or more candidate downlink receive beams, candidate uplink transmit beams, or candidate downlink receive and uplink transmit beam pairs suitable for full-duplex operation based at least in part on the one or more measurements. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a wireless device may select random access channel occasions (ROs) based jointly on synchronization signal block (SSB) measurements and cross-link interference (CLI) measurements. The base station may configure the wireless device with a set of SSB occasions during which to measure SSBs and a set of interference measurement occasions on which to measure CLI caused by other wireless devices. The wireless device may perform measurements on the received SSBs to determine channel quality for communications with the base station, and CLI measurements during the interference measurement occasions to determine whether CLI exceeds a threshold. The wireless device may then select a beam and an associated RO (e.g., a full duplex RO or a half duplex RO) on which to transmit the random access message using the selected beam.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a message scheduling a first resource for a downlink communication between a base station and the first UE, the first resource overlapping with a second resource for a random access channel (RACH) occasion (RO) for use by one or more second UEs. The first UE may receive the downlink communication over the first resource based on receiving the message, where the first resource is full-duplexed with the second resource of the RO and may transmit, over a third resource, an indication of cross link interference between a RACH message transmitted over the second resource and the downlink communication. The first UE may receive a second downlink communication over a fourth resource based at least in part on transmitting the indication.

Abstract: Certain aspects of the present disclosure provide techniques for avoiding transmission configuration indication (TCI) reselection (e.g., due to some bandwidth part (BWP) switching scenarios). An exemplary method generally includes configuring a UE with TCI state information for communication via multiple BWPs, wherein the TCI state information indicates quasi co-location (QCL) assumptions of at least first and second types and determining whether to reconfigure the TCI state of the UE to reflect a BWP switch, based on one or more rules that define BWP switching for reference signals (RSs) of at least one of the QCL assumption types without TCI state reconfiguration. Other aspects and embodiments are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A first network node may receive, in a first time interval, interference signals from a second network node on a portion of uplink resources used by the first network node to receive from a first set of wireless devices served by the first network node in the first time interval. The first network node may transmit, to the second network node, an identifier associated with the second network node and an indication that the second network node is to modify transmission on downlink resources used by the second network node to transmit to a second set of wireless devices served by the second network node. Transmitting the indication that the second network node is to modify transmission on the downlink resources includes transmitting, to the second network node, a signal configured to indicate modifying the transmission on the downlink resources.

Abstract: Aspects of the disclosure relate to Layer 1/Layer 2-centric inter-cell mobility systems and determining timing advance groups (TAGs) within such systems. User equipment (UE) are configured to report one or more grouping of cells to a radio access network (RAN), where the cells for each group have similar propagation delays and/or signal quality. Each reported group can be assigned to a TAG identifier (ID) by the RAN. The RAN may utilize the TAG IDs to time division multiplex uplink and/or downlink transmissions based on the TAG IDs.

Abstract: A user equipment (UE) measures, for each of at least one beam of each of at least one neighboring cell of a UE, at least one reference signal (RS) to obtain at least one layer 1 (L1) beam measurement. The UE derives, for each neighboring cell based on each L1 beam measurement corresponding to the each neighboring cell, at least one L1 measurement reporting value. The transmits, to a serving cell serving the UE 104, a report based on each derived L1 measurement reporting value.

Abstract: Methods, systems, and devices for wireless communications are described. A first relay user equipment (UE) may be configured to receive a first message including a cross-link interference (CLI) indication associated with CLI experienced by a first base station which is associated with signals transmitted by a second base station. The first relay UE may generate, in response to the first message, a second message including the CLI indication, and may transmitting the second message including the CLI indication. In some cases, the first relay UE may transmit the second message directly to the second base station. In additional or alternative cases, the first relay UE may transmit the second message to an additional relay UE for relay to the second base station.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a base station establishing full-duplex communications with a first user equipment (UE) and a second UE. The method may include the first UE receiving an interference threshold from the base station, receiving a pathloss reference signal from the second UE, and determining cross-link interference between the first UE and the second UE based on the pathloss reference signal. The method may include the first UE adjusting a transmit power setting of the first UE in accordance with the cross-link interference and transmitting to the base station an uplink metric report, the uplink metric report including an uplink metric of the first UE that is based on the adjusted transmit power setting of the first UE.
