MICRO SLEEP TECHNIQUES IN STAR TOPOLOGY SIDELINK COMMUNICATIONS

Abstract:

Methods, systems, and devices for wireless communications are described. A hub user equipment (UE) in a star topology may broadcast to a set of peripheral UEs indicating slots when the hub UE will not be in a transmission mode. The hub UE may broadcast a slot format indication to the peripheral UEs to indicate operating modes in a set of slots. In a first group of slots, the hub UE may operate in a forward mode, transmitting sidelink communications to the peripheral UEs. In a second group of slots, the hub UE may operate in a reverse mode, receiving sidelink communications from the peripheral UEs. In slots when the hub UE operates in the reverse mode, if a peripheral UE does not have data or control information, the peripheral UE may enter a sleep mode in one or more slots of the second group to save power.
