Abstract
Methods, systems, and devices for wireless communications are described. Wireless devices may be configured to support techniques for bi-directional discontinuous reception (DRX) alignment and centralized DRX alignment. In the context of bi-directional DRX alignment, DRX configurations at two respective user equipments (UEs) are first established in a first direction, and then DRX configurations are then established in the reverse direction based on the previously-established DRX configurations. In particular, DRX configurations in the reverse direction may be selected such that the Uu and sidelink DRX configurations are aligned at the respective UEs and across the UEs. Comparatively, in the context of centralized DRX alignment, a master base station receives 'candidate' Uu and sidelink DRX configurations for multiple UEs, and selects Uu and sidelink DRX configurations for each UE from the sets of candidate DRX configurations in order to ensure DRX alignment across the respective UEs.
