TYPE 1 AND TYPE 2 HOPPING FOR DEVICE-TO-DEVICE COMMUNICATIONS

摘要

Methods, systems, and devices are described for coordinating a device to device (D2D) hopping scheme with a wide area network (WAN) hopping scheme. In one aspect, a method may include identifying, by a base station, a WAN frequency hopping scheme. The base station may coordinate a D2D frequency hopping scheme a D2D enabled user equipment (UE) with the identified WAN frequency hopping scheme, and communicate the D2D frequency hopping scheme to the D2D enabled UE. In one aspect, the D2D frequency hopping pattern may apply to retransmissions between two D2D enabled UEs. Another method may include receiving, by a D2D enabled UE, a D2D frequency hopping scheme from a base station, where the D2D frequency hopping scheme is coordinated with a WAN frequency hopping scheme. The D2D enabled UE may transmit at least one message to a second D2D enabled UE according to the D2D frequency hopping scheme.
