Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive, from a base station, a control message including an indication associated with a configuration for an interference measurement (IM) report in a channel state information (CSI) report. The UE may determine a setting of the configuration for the IM report based on the indication, which may include one or both of a resource setting associated with IM information in a frequency domain or a spatial setting associated with IM information in a spatial domain. The UE may generate the IM report based on one or both of the resource setting or the spatial setting and may transmit the CSI report including the IM report to the base station.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a CSI report setting that hastens CSI feedback for SVD-based precoding. More specifically, a UE may receive a configuration from a base station for a CSI report setting for providing DL interference feedback to the base station. The configuration may include information indicating a measurement resource on which an interference measurement is performed for generating the DL interference feedback. The UE may transmit a SRS and the DL interference feedback to the base station, the DL interference feedback being independent of the SRS, such that the UE may receive pre-committed CSI-RS from the base station based on the transmitted SRS and DL interference feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may receive configuration information that indicates a set of resources for self-interference measurement associated with a full-duplex communication mode; transmit a signal in accordance with the configuration information; determine a self-interference measurement based at least in part on the signal and the set of resources; and transmit information indicating the self-interference measurement. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal configuring a collection of reference signal transmissions. The UE may identify a resource overlap between the collection of reference signal transmissions and another resource that is unavailable for reference signal transmissions. The UE may identify one or more transmission properties for the collection of reference signal transmissions. The UE may determine, based at least in part on the one or more transmission properties and the resource overlap, whether to omit one or more of the reference signal transmissions of the collection of reference signal transmissions in the corresponding resource overlap or to delay transmission of the collection of reference signal transmissions. The UE may transmit at least a portion of the collection of reference signal transmissions based at least in part on the determining.

Abstract: Methods, systems, and devices for wireless communications are described. A method for wireless communication may include receiving a single frequency networked composite reference signal (SFNed RS) at a first port of a user equipment (UE) and receiving a reference signal (RS) at a second port of the UE that is different than the first port of the UE. The method may also include performing channel estimation for at least one of the first port or the second port based at least in part on receiving the SFNed RS and the RS. A method for wireless communication may include transmitting a first portion of an SFNed RS from a first port of a first transmit/reception point to a UE and transmitting a downlink control information message to the UE that indicates at least one transmission configuration indicator state identifier that identifies the SFNed RS.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Certain aspects of the present disclosure provide techniques for aperiodic channel state information (A-CSI) transmission with slot aggregation. A method that may be performed by a user equipment (UE) includes receiving a grant scheduling a slot aggregated transmission in a plurality of aggregated slots and triggering an aperiodic channel state information (A-CSI) transmission in one of the plurality of aggregated slots. The method includes determining one or more of the plurality of aggregated slots to transmit the A-CSI transmission. The method includes transmitting the A-CSI transmission in the determined one or more of the plurality of aggregated slots.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (such as user equipment (UE)) may receive a downlink grant including an indication to report channel state information. The receiving device may identify, based on the downlink grant, a number of channel state information processing units associated with reporting the channel state information, and may determine that an available number of channel state information processing units is less than the number of channel state information processing units. In some cases, the receiving device may allocate, based on the determining, a set of channel state information processing units including the available number of channel state information processing units and one or more additional channel state information processing units. The receiving device may then transmit the channel state information report based on the set of channel state information processing units.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station operating in full-duplex mode may provide for reception of one or more higher priority transmissions using at least partially overlapping time-frequency resources as used for transmission of lower priority communications. In order to mitigate self-interference at the base station, a transmission power used for the overlapping time-frequency resources may be reduced. The base station may provide an indication of a subset of resources that have a reduced transmission power, an amount of the power reduction for the subset of resources, or both.
