Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of sub-bandwidth part (BWP) channel configurations for wireless communications at the UE, where each sub-BWP channel configuration of the set of sub-BWP channel configurations may include one or more sets of resources spanning at least a portion of a respective BWP in the frequency domain. The UE may receive, from the base station, a control message indicating a first sub-BWP channel configuration of the set of sub-BWP channel configurations, the first sub-BWP channel configuration supporting wireless communication for a full-duplex communication mode and a half-duplex communication mode. The UE may communicate with the base station during a first transmission time interval (TTI) using the first sub-BWP channel configuration indicated via the control message and based on the full-duplex communication mode or the half-duplex communication mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may output a first configuration for a set of resources, the first configuration being associated with a time division duplexing pattern, and the first configuration configuring the set of resources to one of an uplink format, a downlink format, or a flexible format. The network node may output a second configuration configuring one or more resources, of the set of resources, to a sub-band full duplex (SBFD) format based at least in part on the one or more resources satisfying a condition. 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, from a network entity, a channel state information (CSI) report configuration including multiple CSI reference signal (CSI-RS) transmit power configurations. The UE may transmit, to the network entity, the CSI report, wherein the CSI report is associated with at least one CSI processing parameter that is based at least in part on the multiple CSI-RS transmit power configurations. Numerous other aspects are described.

Abstract: A network entity can provide a plurality of downlink (DL) transmissions using a plurality of distributed transmission and reception points (TRPs) in a multiple-in-multiple-out (MIMO) system. The network entity can obtain delay metrics of the DL transmissions from the UE. The UE can generate the delay metrics based on measurements of DL reference signals from the distributed TRPs. The network entity can pre-compensate the DL transmissions based on the delay metrics.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a device such as a user equipment (UE), a base station, or both, to perform a channel noise and interference estimation based on a set of null resources in a data channel. The device may identify a first configuration for a set of demodulation reference signals (DMRSs) in a first set of time periods of a data channel and a second configuration for a set of null resources in a second set of time periods of the data channel. The second set of time periods may be nonoverlapping with the first set of time periods. The device may perform a channel estimation procedure on the data channel based on the null resources and the DMRS resources. The device may process data received via resources of the data channel based on the channel estimation procedure.

Abstract: A UE may estimate a CLI channel state based on a ZP-SRS from a second UE. A network node may transmit to the UE, and the UE may receive from the network node, a CSI-RS. The UE may estimate a downlink channel state based on the CSI-RS from the network node. The UE may estimate one or more eCSF parameters based on the CLI channel state, the downlink channel state, two or more interference hypotheses, and at least one of a CPU specification, a timing specification, or a UE capability indication. The UE may transmit to the network node, and the network node may receive from the UE, an eCSF report based on the one or more eCSF parameters.
