Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive an indication of one or more of: an identifier of a neighbor user equipment (UE) associated with a neighbor network node, a location and mobility status of a UE served by the network node, or beam adaptation information of the UE served by the network node. The network node may perform an interference mitigation for the UE served by the network node based at least in part on the indication of one or more of: the identifier of the neighbor UE, the location and mobility status of the UE, or the beam adaptation information of the UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A network entity may transmit, and a user equipment (UE) may receive, control signaling that configures or schedules sub-band full-duplex (SBFD) slots or symbols. The network entity may transmit, and the UE may receive, control signaling that schedules occasions, a resource block group, or a precoding resource block group that may overlap with the SBFD slot or symbols. The UE and the network entity may regulate communications based on application of one or more rules pertaining to communications when scheduled resource overlaps with a SBFD slot or symbol.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, a first network entity receives, from a second network entity, an uplink (UL) muting indication. The UL muting indication includes a UL muting pattern for a cross-link interference (CLI) measurement related to the first network entity and the second network entity. The first network entity further indicates, to one or more user equipment (UEs), the UL muting pattern for the one or more UEs to restrict first UL transmission to the first network entity based on the UL muting pattern. The method reduces the interferences during the measurement and transmission and improves the efficiency of wireless communication.

Abstract: A UE receives information indicating a set of slots or symbols for a subband full duplex (SBFD) operation. The UE also receives a configuration of an SBFD format including at least a first subband for uplink communication and a second subband for downlink communication. The UE further receives an indication that indicates for the UE to update the SBFD format for at least a subset of the set of slots or symbols.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving a configuration for switching between a full frequency bandwidth slot in a half duplex mode, and a partial frequency bandwidth slot in a subband based base station full duplex (SBFD) mode. The full frequency bandwidth slot is for uplink communications or downlink communications. The partial frequency bandwidth slot is for the uplink communications corresponding to an uplink subband or for downlink communications corresponding to at least one downlink subband. The method also includes switching, in accordance with the configuration, between the full frequency bandwidth slot and the partial frequency bandwidth slot.

Abstract: A first user equipment (UE) receives a configuration of a channel state information (CSI) report from a base station. The configuration includes an indication of a sounding reference signal (SRS) or uplink demodulation reference signal (DMRS) transmitted from a second UE as an interference measurement resource (IMR). The base station configures the second UE to transmit the SRS or the uplink DMRS on the IMR. The first UE measures the IMR to determine a cross-link interference of the second UE to the first UE. The UE transmits the CSI report. The CSI report includes at least one channel characteristic that takes into account the cross-link interference of the second UE. The CSI report may include information for a plurality of CSI-RS resource indicators (CRIs), each CRI associated with a same channel measurement resource (CMR) and a different IMR corresponding to a different second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may implement a subband full duplex communication scheme. For a half duplex UE, each slot may be configured as either a downlink slot or an uplink slot. A half duplex UE may be scheduled with a transmission in a conflicting (e.g., opposite) direction with respect to the configured slot direction for the UE. The UE may determine whether to communicate a scheduled transmission in a conflicting direction of the configured slot direction in accordance with a conflict resolution scheme. A UE may receive scheduling information for a second transmission that is scheduled for the same direction as the slot in addition to the transmission scheduled for the opposite direction as the slot. The UE may apply the conflict resolution scheme to determine which transmission to communicate.

Abstract: A network node may transmit an RS to a UE in a symbol or a slot. The RS may extend over a plurality of downlink subbands that have non-contiguous subcarriers in the symbol or the slot. At least two downlink subbands in the plurality of downlink subbands may be separated by an uplink subband in the symbol or the slot. The plurality of downlink subbands and the uplink subband may be associated with a subband full duplex operation at a network node. The RS may include a CSI-RS. The UE may measure the RS from the network node in the symbol or the slot. The UE may generate at least one CSI metric based on the measurement of the RS. The network node may receive a CSI report from the UE based on the RS and at least one CSI metric.

Abstract: A wireless device, such as a user equipment (UE), may receive first scheduling information with first resources for periodic transmissions with a first beam based on a half-duplex mode. The wireless device may receive second scheduling information for second resources associated with a second beam that is incompatible with the first beam for full duplex communication including downlink reception and uplink transmission that overlaps in time. The wireless device may adjust communication in response to the first beam being incompatible with the second beam for the full duplex communication.
