Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message indicating that a symbol for a repetition of a sounding reference signal (SRS) resource in a first slot is canceled or blocked. The UE may drop transmission of one or more other symbols for the SRS resource in the first slot based at least in part on the message. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for randomization of reconfigurable intelligent surface (RIS) signals. A method for wireless communication includes determining a random reflection parameter for each of one or more RISs. The random reflection parameter is random over time for the one or more RISs. The method includes applying random values of the random reflection parameter at different times at each of the one or more RISs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from one or more of a network node or a second UE, a reference signal in a first subband of a sub-band full-duplex (SBFD) slot. The first UE may transmit, to the network node, a cross-link interference (CLI) report that indicates: a first CLI measurement associated with the reference signal in the first subband of the SBFD slot, and a second CLI measurement associated with a second subband of the SBFD slot. Numerous other aspects are described.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a first common downlink channel or reference signal in a downlink slot or symbol. The UE may receive, from the network node, a second common downlink channel or reference signal in at least one downlink sub-band associated with a sub-band full duplex (SBFD) slot or symbol. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a bandwidth part (BWP) configuration indicating that a BWP is configured with cross sub-band scheduling, the BWP configuration indicating at least one sub-band associated with the BWP in which grants are to be received. The UE may receive, in the at least one sub-band, downlink control information (DCI) including a grant that schedules a communication in one or more sub-bands associated with the BWP. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for indicating subband configurations in subband full duplex (SBFD) operation. An example method that may be performed by a user equipment (UE) includes receiving signaling indicating at least one of time or frequency locations of at least one uplink (UL) subband and at least one downlink (DL) subband for subband full duplex (SBFD) communications; and performing SBFD communications, in one or more symbols or slots, based on the signaling.

Abstract: Aspects are provided which allow a network entity to configure and a UE to transmit subband CSI reports in full duplex slots. Initially, the UE receives a CSI report configuration indicating a plurality of CSI subbands of at least one bandwidth part BWP. Subsequently, the UE receives a CSI-RS in a slot associated with a full duplex mode, the slot being further associated with a frequency band including a downlink subband and an uplink subband. Afterwards, the UE transmits a CSI report, where the CSI report includes first CSI associated with the CSI-RS for a first one of the CSI subbands overlapping in frequency with the downlink subband, and the CSI report lacks second CSI for a second one of the CSI subbands overlapping in frequency with the uplink subband.

Abstract: Apparatus, methods, and computer program products for full duplex communication are provided. An example method may include receiving a FDRA indication from a network entity, where the FDRA indication allocates a set of scheduling resources in a first band of a DL band or a UL band and includes an indication associated with a resource utilization in a second band of the UL band or the DL band, and where the DL band and the UL band overlap in a time domain. The example method may include receiving, from the network entity, a RRC configuration associated with a guard band between the UL band and the DL band. The example method may include communicating, with the network entity, a UL transmission or a DL transmission based on at least one of the set of scheduling resources, the guard band, or the resource utilization in the second band.
