Title:
TECHNIQUES AND APPARATUSES FOR COMMUNICATION RELAY DISCOVERY
Document Type and Number:
WIPO Patent Application WO/2019/005283
Kind Code:
A8
Abstract:
User equipments (UEs) may transmit periodic discovery broadcasts to enable another UE to establish a relay connection to a network. When the UEs transmit respective discovery broadcasts, the discovery broadcasts may cause excessive utilization of network or battery resources. In some aspects, described herein, a first UE, based at least in part on failing to receive a periodic discovery broadcast, may transmit a search signal. A second UE may refrain from transmitting periodic discovery broadcasts based at least in part on a first energy metric not satisfying a first energy metric threshold, but may transmit a discovery broadcast as a response to the search signal based at least in part on a second energy metric satisfying a second energy metric threshold, thereby enabling the first UE to establish a connection to a base station using the second UE as a relay.
