Embodiment Construction

[0039] A wireless communication system may support both direct links (eg, direct links) and side-link communication links for communication between wireless devices. A direct link may refer to a communication link between a user equipment (UE) and a base station. For example, the direct link may support uplink signaling, downlink signaling, connection procedures, and the like. A sidelink communication link may refer to any communication link between similar wireless devices (eg, a communication link between UEs, a communication link between a transmitting UE and a relaying UE, etc.). It should be noted that although the various examples provided herein are discussed for UE sidelink devices, such sidelink techniques may be used for any type of wireless device that communicates using sidelink. For example, a side link can support device-to-device (D2D) communication, vehicle-to-everything (V2X) or vehicle-to-vehicle (V2V) communication, message relay, discovery signaling, beaco...

Abstract

Methods, systems, and devices for wireless communication are described. A device communicating with a second device may receive a message from the second device. After receiving, the device selects between a decode-forward (DF) or amplify-forward (AF) transmission scheme to forward the message to the base station. The selection may be made using one or more trigger conditions associated with the transmitting device, the receiving device, or the base station, such as power availability at the device, processing capability of the device, or beam parameters (such as beam width, array gain), or other conditions. After the selection, the device may forward the packet from the second device to the base station using the selected transmission scheme.

Description
