Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may perform one or more operations for receive antenna switching. For example, a UE may receive a set of reference signals from a base station using one or more ports of the UE. Based on receiving the set of reference signals, the UE may generate channel state information (CSI) associated with a set of antenna ports. In some cases, the UE may generate CSI based on receiving a configuration indicating the set of antenna ports. The UE may transmit, to the base station, a CSI report including the CSI information associated with the set of antenna ports and an indication of the associated antenna ports. The base station may receive the CSI report and may communicate with the UE using a set of precoders associated with the set of indicated antennas ports.

Abstract: Methods, systems, and devices for wireless communications are described that provide for channel state information (CSI) feedback for multiple discrete Fourier transform (DFT) beams on multiple transmission layers. A user equipment (UE) may report a total number of non-zero power DFT beams across all of the transmission layers. The UE may be configured with a total number of leading beams (Ktotal) across all of the transmission layers for which to provide high quantization feedback. When the total number of non-zero DFT beams across all the transmission layers exceeds the configured total number of leading beams across all the transmission layers, the UE may report high-resolution quantization feedback for Ktotal non-zero power precoding coefficients having the highest amplitude coefficients, and may report low-resolution quantization feedback for the remaining non-zero power precoding coefficients. A base station may receive the CSI feedback to determine a precoding matrix.

Abstract: Certain aspects of the present disclosure provide techniques for reducing overhead for channel state information (CSI). Certain aspects provide a method for wireless communication. The method generally includes receiving a channel state information reference signal (CSI-RS), determining one or more feedback components associated with a CSI feedback type based on the CSI-RS, identifying that a payload of the one or more feedback components is to be compressed, compressing the payload, and reporting the compressed payload.

Abstract: Methods, systems, and devices for wireless communications are described for configuring contention-free uplink resources and contention-based uplink resources as preconfigured uplink resources (PUR) available for a user equipment (UE) to transmit one or more uplink transmissions without a specific allocation for the uplink transmission from a base station. Each of two or more UEs may be configured with separate portions of contention-free PUR that each UE may use to transmit a relatively small first uplink communication that provides an indication that the UE will transmit a relatively larger second uplink communication using contention-based PUR. The UE may transmit a buffer status report (B SR) using the contention-free PUR. The first communication may provide an indication of one or more physical layer parameters associated with the second uplink communication. The UE may transmit the second uplink communication using the indicated one or more physical layer parameters via the contention-based uplink resource.

Abstract: Idle discontinuous reception (I-DRX) cycles at a user equipment (UE) may be extended via leveraging of paging assistance from a second UE. For example, a low complexity UE may have a connection to a network (e.g., via a link to a base station) as well as a connection to another UE (e.g., via a device-to-device link to a regular UE). In cases where such a low complexity UE receives paging messages from the network, a UE associated with a device-to-device link of the low complexity UE may monitor paging messages on behalf of the low complexity UE. As such, the low complexity UE may extend its I-DRX cycle, as the assisting UE monitors paging information for the low complexity UE. The assisting UE may forward paging information for the low complexity UE according to paging occasions of the extended I-DRX cycle of the low complexity UE.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit, and a user equipment (UE) may receive, signaling identifying a configuration of a set of multiple machine learning (ML) models for channel characteristic prediction. The channel characteristic prediction may include a channel characteristic prediction for each ML model of the set of multiple ML models based on a respective reference signal resource of the set of multiple reference signal resources. The network entity may obtain an input to the set of multiple ML models based on performing one or more measurements associated with the set of multiple reference signal resources. The network entity may output, and the UE may obtain, the input. The UE may process the input using at least one ML model of the set of multiple ML models to obtain the channel characteristic prediction of the at least one ML model.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling hybrid automatic repeat request (HARQ) feedback and controlling the transmit power of the HARQ feedback. An example method generally includes generating a configuration for physical uplink control channel (PUCCH) resource sets assigned to at least one user equipment (UE), wherein each of the PUCCH resources sets comprises PUCCH resources, transmitting the configuration for the PUCCH resource sets to the at least one UE, generating an uplink control reporting indication indicating the PUCCH resources associated with downlink demodulation reference signal (DMRS) port groups, transmitting the uplink control reporting indication, to the at least one UE, for use in reporting uplink control information (UCI), and receiving at least a part of the UCI associated with at least one of the downlink DMRS port groups from the at least one UE via the PUCCH resources indicated in the uplink control reporting indication.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive, from a base station, a configuration for a channel state report setting. The UE may transmit, to the base station, a request for additional reporting quantities for the channel state report setting or to change one or more parameters of the channel state report setting based at least in part on the configuration. For example, the UE may transmit a request to change the periodicity of the channel state report, to transmit an additional, unscheduled channel state report, to increase or decrease the channel state information reference signal resources or the synchronization signal block resources associated with the channel state report setting, or to report a beam change incident. The UE may transmit a channel state report based on the configuration and the request to change the channel state report setting or the one or more parameters.
