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.
