Abstract: Methods, systems, and devices for wireless communication are described to estimate interference for concurrent uplink and downlink communications based on an indication of one or more one or more characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). The base station or the second UE may transmit, to a first UE, an indication of one or more characteristics of an uplink signal, such as a baseband of the uplink signal or one or more parameters of the uplink signal. The first UE may use the characteristic(s) of the uplink signal to estimate the baseband of the uplink signal and cancel interference associated with the uplink signal. For example, the first UE may use the baseband signal to estimate the interference and may subtract the estimated interference from a downlink signal received at the first UE.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may allow for a victim user equipment (UE) to perform cross-link interference (CLI) measurements in a guard band. The victim UE may receive a resource configuration from a network entity to perform CLI received strength signal indicator (RSSI) measurements in the guard band resources. Additionally, or alternatively, the victim UE may receive a sounding reference signal (SRS) resource configuration from the network entity to perform CLI reference signal received power (RSRP) measurements in the guard band resources. In such examples, the aggressor UE may receive an SRS resource configuration from the network entity for transmitting SRSs to the victim UE in the guard band resources. The control signaling configuring the SRS resources may indicate, to the aggressor UE, a threshold transmit power, a transmit beam restriction, or both, with which to transmit the SRSs.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support channel state information (CSI) reporting based on full-duplex reference signals, half-duplex reference signals, or both. A user equipment (UE) may receive, from a network entity, a CSI reporting configuration that includes one or more parameters for full-duplex CSI reporting, half-duplex CSI reporting, or both. The network entity may transmit a full-duplex reference signal, a half-duplex reference signal, or both to the UE based on the CSI reporting parameters. The UE may obtain measurements of the reference signals. The UE may transmit one or more CSI reports based on the measurements. The CSI reports may be transmitted at least a threshold time period after a corresponding reference resource. The threshold time period may be based on a duplexing mode associated with the CSI report.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of dynamic resource block (RB) bundling for downlink transmissions, the dynamic RB bundling associated with a first precoding bundle size set and a second precoding bundle size set. The UE may receive a grant scheduling a downlink transmission associated with a subband full duplex slot, the grant comprising a bundling size indication identifying either the first precoding bundle size set or the second precoding bundle size set. The UE may receive the downlink transmission associated with the subband full duplex slot according to the grant, the downlink transmission received via contiguous frequency resources associated with RB bundling and identified based at least in part on an RB size identified by the bundling size indication, wherein the RB size comprises a narrowband bundle size value, a wideband bundle size value, or a combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating one or more channel state information (CSI) report configurations that configure one or more CSI interference measurement (CSI-IM) resources, including a CSI-IM resource associated with a full-duplex (FD) set of symbols and a CSI-IM resource associated with a half-duplex (HD) set of symbols. The UE may perform interference measurements associated with at least one of the FD set of symbols, using the CSI-IM resource associated with the FD set of symbols, or the HD set of symbols, using the CSI-IM resource associated with the HD set of symbols. The UE may transmit one or more CSI reports reporting the interference measurements associated with the at least one of the FD set of symbols or the HD set of symbols. Numerous other aspects are described.

Abstract: A user equipment (UE) may identify at least one suitable configuration for sounding reference signal (SRS) antenna switching and transmit the at least one suitable configuration for SRS antenna switching to the base station via a medium access control (MAC) control element (CE) (MAC-CE) or a radio resource control (RRC) message. The base station may receive the at least one suitable configuration for SRS antenna switching from the UE, and transmit an active SRS antenna switching configuration to the UE, the active SRS antenna switching configuration based on the suitable configuration for SRS antenna switching received from the UE.
