Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The method generally includes receiving a downlink control information (DCI) with at least one block configured to trigger aperiodic sounding reference signal (SRS) transmission from the UE on at least one SRS resource set, determining a transmit power control (TPC) command to apply to the A-SRS if the DCI lacks a transmit power control (TPC) command for the at least one SRS set, and transmitting the A-SRS in accordance with the DCI and the determined TPC command.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration identifying a first set of frequency resources for transmitting a sounding reference signal, where the sounding reference signal may be used at least for downlink channel state information acquisition. The UE may receive an indication of an association between the configuration for the sounding reference signal and a second set of frequency resources and determine, based on the association, values for one or more sounding reference signal transmission parameters for the first set of frequency resources. The UE may transmit the sounding reference signal on the first set of frequency resources based on the determined one or more values.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first configuration of one or more channel state information reference signal resources and a second configuration of a channel state information report associated with the one or more channel state information reference signal resources. In some cases, the second configuration may include at least one of an indication of a codebook, a set of codebook restriction sets, and a configured bandwidth. The UE may then identify a mapping between one or more frequency-domain subbands of the configured bandwidth and each codebook restriction set of the set of codebook restriction sets, and transmit, to the base station, a report indicating one or more precoding matrix indicators from the codebook for each of the one or more frequency-domain subbands based on the mapping.

Abstract: Methods, systems, and devices for wireless communications are described that support virtual resource block (RB) to physical RB mapping in duplex slots. The described techniques enable a user equipment (UE) to select an interleaving configuration such as a full duplex or half duplex interleaving configuration for a slot that may be configured for full duplex communications. In some cases, the UE may use a default interleaving configuration for a given slot or may determine the interleaving configuration based on a bandwidth part (BWP) position or resource bandwidth within the slot, such as a location within the frequency domain of a downlink BWP relative to an uplink BWP.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving multiple neural network training configurations for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes training each of a group of neural network decoder/encoder pairs in accordance with the received training configurations. A method of wireless communication, by a base station, includes transmitting multiple neural network training configurations to a user equipment (UE) for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes receiving a neural network decoder/encoder pair trained in accordance with the training configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (such as a user equipment (UE)) may receive a downlink grant including an indication to report a first channel state information and a second grant including an indication to report a second channel state information. In some cases, the second grant may be received after the downlink grant. The UE may determine a transmission order associated with the first channel state information and the second channel state information based on a configuration, and may transmit the first channel state information and the second channel state information according to the transmission order.
