RELAYING AND RELATED CONFIGURATION SIGNALING FOR WIRELESS COMMUNICATIONS

Abstract:

Methods, systems, and devices for wireless communications are described. A wireless device may configure a relay configuration for a set of user equipments (UEs). The relay configuration may include a set of first direction transmission opportunities and corresponding second direction transmission opportunities. The relay configuration may be activated or deactivated, such as on a packet-by-packet basis. When the relay configuration is activated, a first UE and one or more second UEs may sequentially transmit a packet using the first direction transmission opportunities so as to be receivable by the wireless device and each other. The relay process may continue, for example, until the wireless device successfully receives the packet. The wireless device may monitor the first direction transmission opportunities and transmit positive or negative acknowledgments during the second direction transmission opportunities to indicate whether it has successfully received the packet.
