An eNB is configured to perform different methods for assigning discovery resources. One method includes receiving a request for discovery resources from an announcing user equipment (UE); allocating a plurality of discovery resources in response to the request; and transmitting a message indicating the plurality of discovery resources, the transmitted message configured to be used by a monitoring UE to determine which discovery resources to monitor. In some embodiments, this may include updating a message to indicate which discovery resources have been allocated, and broadcasting the updated message to a plurality of UEs including the monitoring UE.
