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: The present disclosure relates to methods and devices for dynamic resource multiplexing. In one aspect, a base station can transmit a first uplink/downlink configuration for communicating with one or more User Equipments (UEs). The first uplink/downlink configuration can comprise a set of fixed resources configured for uplink communication without downlink resources for downlink communication or for downlink communication without uplink resources for uplink communication. The base station can also transmit a second uplink/downlink configuration for communicating with the one or more UEs. The second configuration can comprise a flexible resource configuration. Additionally, the base station can communicate with a least one of the one or more UEs based on the first uplink/downlink configuration or the second uplink/downlink configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A bandwidth reduced low-tier user equipment (UE) may receive a signal identifying a control resource set for the UE to monitor for control information scheduling communications between the UE and a base station, the control resource set comprising a plurality of control channel elements organized across more than three symbols and comprising one or more first resource element groups mapped to a first monitoring occasion and one or more second resource element groups mapped to a second monitoring occasion. The UE may receive, during the first monitoring occasion, at least a first portion of the control information on the one or more first resource element groups. The UE may receive, during the second monitoring occasion, at least a second portion of the control information on the one or more second resource element groups. The UE may communicate with the base station in accordance with the control information.

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.

Abstract: The described techniques relate to improved methods, systems, devices, or apparatuses that support channel state information feedback for semi-open-loop and open-loop schemes. The described techniques provide for a user equipment (UE) to determine an open-loop, semi-open-loop, or closed-loop transmission scheme for deriving channel quality information (CQI). In the case of determined open-loop transmission scheme, the UE may select a transmission scheme corresponding to a time offset value and a precoder cycling granularity value. The UE may determine one or more of a time offset value, a precoder cycling granularity value, and a precoding matrix indicator (PMI) for a channel state information (CSI) report, and generate CQI accordingly. Additionally, the UE may include the determined values in the CSI report to indicate the transmission scheme used for the CQI derivation. Based on the CQI, the base station can then determine the transmission scheme and perform link adaption accordingly.
