Abstract: Certain aspects of the present disclosure provide techniques for guard period configuration between subband full duplex and half duplex symbols and slots. An example method that may be performed at a user equipment (UE) includes obtaining an indication of a guard period during which a cell in which the UE is communicating will switch between subband full duplex (SBFD) communications and half duplex (HD) communications; and performing one or more actions during the guard period, in accordance with the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit capability information indicating that the UE has a capability for an intra-band conflict resolution rule for resolving a conflict, in one or more symbols, between a first communication on a first semi-statically configured resource of a first cell and a second resource on a second cell according to a first priority of the first communication, wherein the first semi-statically configured resource is associated with a first link direction and the second resource is associated with a second link direction different than the first link direction. The UE may perform at least one of the first communication or the second communication according to the intra-band conflict resolution rule. Numerous other aspects are described.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to detect and mitigate cross link interference (CLI). A method of a wireless communication at a first user equipment (UE), comprises determining, at the first UE, a communication failure on a downlink (DL) channel indicative of CLI from transmission of a communications signal by a second UE on an uplink (UL) channel; based on detecting the communication failure, transmitting a request for CLI measurement resources to a network entity; receiving, at the first UE, a CLI reference signal configuration from the network entity; receiving, at the first UE, a CLI reference signal from the second UE; and transmitting, to the network entity, a CLI measurement report based on the CLI reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a channel state information report in a subband full duplex slot using a first guard band. The UE may receive a physical downlink shared channel (PDSCH) communication. The UE may transmit an indication of an adjustment, based at least in part on the PDSCH communication, to use for a second guard band with respect to the first guard band. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a beam configuration for each physical cell identifier (PCI) of a set of candidate PCIs. A beam configuration for a PCI may include, for example, transmission configuration indicator (TCI) states for downlink channels and reference signals or spatial relations for uplink channels and reference signals. The UE may receive an indication of a selected subset of PCIs of the set of candidate PCIs. The UE may apply the beam configuration for each PCI of the selected subset of PCIs based on the indication of the selected subset of PCIs. The UE may then communicate according to the beam configurations for the selected subset of PCIs.

Abstract: A first network node may identify at least one of a usage probability or an interference probability of each Rx beam of the first network node in a plurality of Tx-Rx beam pairs associated with the first network node and the second network node. The usage probability may include a usage metric that indicates a likelihood of using a beam. The interference probability may include an interference metric that indicates a likelihood of a Tx beam of the second network node interfering with an Rx beam of the first network node. The first network node may transmit a first indication of the usage probability or the interference probability of each Rx beam in the plurality of Tx-Rx beam pairs. The second network node may receive the first indication and adjust a beam schedule for at least one of the plurality of Tx-Rx beam pairs based on the received first indication.
