Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a sub-band full-duplex (SBFD) configuration of a cell serving the UE. The SBFD configuration may indicate a first set of resources for downlink communications and a second set of resources for uplink communications. The first set of resources and the second set of resources may include non-overlapping frequency resources in a same time interval. The UE may receive a control message that indicates a pre-emption of the first set of resources or a cancellation of the second set of resources. Accordingly, the UE may determine that downlink transmissions in at least a portion of the first set of resources are pre-empted or that uplink transmissions in at least a portion of the second set of resources are cancelled based on the control message and the SBFD configuration of the cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, control signaling that includes sounding reference signal (SRS) configuration information associated with an increased quantity of SRS ports. The SRS configuration information may include a quantity of symbols via which to transmit SRSs, a frequency resource comb for each respective symbol, and a threshold quantity of cyclic shifts. The UE may map a first subset of SRS ports to a first symbol and map a second subset of SRS ports to a second symbol. The UE may transmit, and the network entity receive, the SRSs using the first subset of SRS ports via the first symbol according to a first frequency resource comb and respective cyclic shifts and using the second subset of SRS ports via the second symbol according to a second frequency resource comb and respective cyclic shifts.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a set of transmission time intervals (TTIs) including at least one TTI to be used for full-duplex communications. The UE may receive control signaling that indicates a frequency domain resource allocation (FDRA) for a physical uplink channel transmission in a first TTI. The UE may determine whether a second TTI is available for transmitting one or more repetitions of the physical uplink channel transmission based on comparing the FDRA to resources allocated to the second TTI. For example, the second TTI may be available if one or more physical resource blocks (PRBs) of the FDRA are non-overlapping in a frequency domain with downlink resources allocated to the second TTI. The UE may transmit the one or more repetitions in the second TTI based on the second TTI being available.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms signaling non-linearities to a victim user equipment (UE) for interference cancellation in a wireless communication system. A victim UE may experience interference from an uplink transmission by an aggressor UE to a base station. The victim UE may obtain a power amplifier model associated with the aggressor UE. The power amplifier may include a non-linearity model of a power amplifier of the aggressor UE causing the interference on the victim UE. The power amplifier model obtained by the victim UE may be dependent on various parameters, such as a transmit power used by the aggressor UE to transmit the uplink transmission causing the interference. Based on the aggressor UE transmit power, the victim UE may select parameters for power amplifier model and may estimate the interference caused by the uplink transmission for interference cancellation.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE), a plurality of uplink configured grant (UL-CG) configurations and receiving, by the UE, an UL-CG. The method further includes selecting, based on a resource configuration associated with a slot, an UL-CG configuration from among the plurality of UL-CG configurations for an occasion of the UL-CG that is to occur during the slot. The method further includes performing an uplink transmission during the occasion of the UL-CG based on the selected UL-CG configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on an estimated cross link interference (CLI) at the UE. For example, a network entity may indicate, to a first UE and a second UE, transmission parameters of a multi-port CLI-reference signal (CLI-RS) that is associated with estimation of CLI channel between the first UE and the second UE. The network entity may indicate, to the first UE, one or more precoding parameters associated with uplink precoding at the second UE. The second UE may transmit the multi-port CLI-RS to the first UE, and the network entity may transmit a CSI-reference signal (CSI-RS) to the first UE. The first UE may transmit a report that includes CSI based on the multi-port CLI-RS, the CSI-RS, and the one or more precoding parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on a precoded cross link interference (CLI) channel at the UE. For example, a network entity may transmit a control message to a first UE that indicates a reporting configuration for indicating CSI associated with a channel between the first UE and the network entity. The first UE may generate the CSI based on a precoded CLI channel at the first UE associated with at least one uplink transmission associated with a second UE, where the precoded CLI channel is generated using at least one estimated CLI channel associated with the at least one uplink transmission and at least one candidate precoding matrix associated with the second UE. In accordance with the reporting configuration, the first UE may transmit the CSI to the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may receive a capability message from a user equipment (UE) based on a number of receive antennas exceeding a number of transmit antennas at the UE. The base station may configure the UE with a mapping between sounding reference signal (SRS) resources and bit sequences, or SRS resource indices (SRIs), based on the capability message. The base station may transmit a control message including one or more SRIs indicating respective SRS resources. The UE may use the one or more SRIs included in a control message from the base station to select respective SRS resources from a resource set. Once the UE selects one or more SRS resources, the UE may transmit one or more SRSs in the SRS resources.
