Abstract: Methods, systems, and devices for wireless communications are described. A relay node may determine a channel status for each of a plurality of downlink beamforming directions between a parent node and the relay node based at least in part on a downlink beamforming direction between the relay node and a child node. The relay node may transmit a report to the parent node indicating at least a subset of the channel statuses and an indication that a respective downlink beamforming direction of the plurality of downlink beamforming directions corresponds to a respective channel status in the subset of the channel statuses. The relay node may receive a grant from the parent node indicating a first downlink beamforming direction. The relay node may monitor for a downlink transmission from the parent node based at least in part on the grant and the first downlink beamforming direction.

Abstract: Methods, systems, and devices for wireless communications are described for a user equipment (UE) operating in a full-duplex mode to report of channel state information based on an estimate of self-interference associated with concurrent uplink and downlink transmissions using at least partially overlapping frequency resources. A base station may transmit downlink reference signals to the UE for measurement and generation of the channel state information, and the base station may use the channel state information reported by the UE to schedule the simultaneous transmission and reception such that the self-interference from full-duplex mode operations is mitigated.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) comprising a grant scheduling a data transmission for the UE, the data transmission associated with a rateless coding scheme. The UE may determine to disable feedback information for the data transmission based at least in part on the rateless coding scheme and one or more of: the DCI, a resource associated with the DCI, or a semi-persistent scheduling configuration associated with the data transmission. The UE may perform or monitor for the data transmission according to the DCI and the rateless coding scheme. The UE may perform or monitor for the feedback information for the data transmission according to the determining.

Abstract: Port selection codebook enhancements are disclosed for spatial and frequency domain density (FDD) reciprocity. A base station may generate and signal a channel state information (CSI) report configuration including configuration of multiple CSI-reference signal (CSI-RS) port groups, wherein each group includes one or more CSI-RS ports, and each group is associated with one or more codebook subset restrictions (CBSRs). Using the configured restrictions of the CBSRs, served user equipments (UEs) may determine linear combination coefficient feedback based on channel measurements of selected port groups and signals the feedback to the base station. Once the base station receives the feedback it may then determine a hybrid CSI-RS codebook using both the configured CSI-RS port groups and the linear combination coefficients. The base station may then transmit downlink data encoded with a precoding matrix selected from the codebook. Other aspects and features are also claimed and described.

Abstract: A base station may determine co-phase information and uplink precoding information (e.g., user equipment (UE) precoder information) based on one or more received sounding reference signals (SRSs) from a UE. The UE may adjust precoders or co-phase for different SRS transmissions over the one or more configured SRS resources. As such, the base station may indicate either co-phase information or uplink precoding information via an SRS resource indicator (SRI), and may transmit an explicit indication of the remaining co-phase information or uplink precoding information in addition to the SRI. In other examples (e.g., when only a single SRS resource is configured), the base station may transmit an index corresponding to uplink precoding information, as well as a separate indication of co-phase information. In some cases, a port selection pattern may be included with an explicit indication, indicating a selection of antenna port indices the precoder or co-phase index applies to.

Abstract: Methods, systems, and devices for wireless communications are described in which sequence groups, and sequence hopping patterns may be used to distinguish concurrent non-orthogonal multiple access (NOMA) transmissions. A wireless device, such as a user equipment (UE), may identify, for a message, a first transmission opportunity from a plurality of transmission opportunities associated with grant-free uplink contention-based transmissions (e.g., NOMA transmissions); select a multiple access (MA) signature sequence from a group of MA signature sequences associated with the first transmission opportunity; identify a hopping pattern associated with the MA signature sequence; and transmit one or more redundancy versions of the message in one or more of the plurality of transmission opportunities comprising the first transmission opportunity according to the MA signature sequence and the hopping pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, configuration information indicating that the UE is to compress a precoding matrix indicator in connection with channel state information reporting, wherein the precoding matrix indicator is to be compressed based at least in part on a quantization dependency between transmission layers or an orthogonality relationship between the transmission layers, and wherein the configuration information is associated with a type II, higher rank codebook for multiple input multiple output configuration. The UE may transmit, to a base station (BS), the compressed precoding matrix indicator to the base station based at least in part on receiving the configuration information. The UE and BS may use a communication configuration based at least in part on a precoding matrix indicator recovered from the compressed precoding matrix indicator. Numerous other aspects are provided.
