Abstract: Disclosed are techniques related to wireless communication system to enable full duplex communication. A network node may include a transceiver, a memory, and a processor communicatively coupled to the transceiver and the memory. The transceiver, memory, and processor may be configured to determine downlink (DL) parent and child link priorities for parent and child time-domain resources that overlap in time at least partially. The transceiver, memory, and processor may also be configured to determine DL parent and child beams based on the DL parent and child link priorities. The transceiver, memory, and processor may further be configured to notify the parent node of the DL parent beam for the parent and child time-domain resources. The transceiver, memory, and processor may yet further be configured to concurrently receive parent traffic from the parent node using the DL parent beam and transmit child traffic to the child node using the DL child beam.

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. A user equipment (UE) located in a near field of a base station may receive a beamformed signal from the base station via a three-dimensional (3D) transmission beam. The UE may receive the signal at an antenna panel and detect a signal strength distribution of the signal at the antenna panel. The UE may calculate a signal weight for each portion of the antenna panel and determine beam adjustment information based on the signal weights. The UE may report the beam adjustment information to the base station, and the base station may use the beam adjustment information to adjust the beamwidth of the 3D transmission beam for subsequent transmissions to the UE, which may increase a beamforming gain at the antenna, and improve communication data rate.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may determine a first set of time-frequency resources, within a time duration, for full-duplex communications and a second set of time-frequency resources, within the time duration, for non-full-duplex communications. The node may transmit to a wireless communication device and based at least in part on determining the first set of time-frequency resources and the second set of time-frequency resources, an indication of the first set of time-frequency resources, the second set of time-frequency resources, and corresponding transport formats for the first set of time-frequency resources and the second set of time-frequency resources. Numerous other aspects are provided.

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: 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.
