1. A method for operating a mobile device adapted for device-to-device (D2D) operation, the method comprising:
determining, by the mobile device, a utilization measure for discovery resources (DRs) allocated for D2D discovery in a communications system, wherein determining the utilization measure comprises:
determining a signal to interference plus noise ratio (SINR) value for each of the DRs allocated for D2D discovery;determining a number of DRs with SINR values meeting a SINR threshold; andderiving the utilization measure in accordance with the number of DRs with SINR values meeting the SINR threshold, and the number of DRs allocated for D2D discovery, wherein each of the DRs comprises a set of resource elements (REs), and wherein the DRs are located in a set of subframes; comparing, by the mobile device, the utilization measure to a utilization threshold; determining, by the mobile device, that a reporting criterion is satisfied in response to the utilization measure exceeding the utilization threshold; and sending, by the mobile device, a utilization measure report to an evolved NodeB (eNB) in response to the reporting criterion being satisfied, wherein the utilization measure report is configured to prompt an adjustment to a number of DRs allocated for D2D discovery when an adjustment condition is met. |
