DEVICE-TO-DEVICE DISCOVERY SIGNALING FOR RADIO RESOURCE ALLOCATION

摘要

A user device may transmit a request to a base station for an allocation of device-to-device (D2D) discovery resources. In response to the request, the user device may receive from the base station a response that indicates whether the D2D discovery resources allocated to the user device are common resources (e.g. Type 1) or dedicated resources (e.g. Type 2, including two different variations: Type 2A and Type 2B).
