System and method for signaling network assigned radio resources for proximity discovery

摘要

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.

主权项

1. A method for assigning discovery resources at a first eNodeB (eNB), the method comprising:
receiving a request for discovery resources from an announcing user equipment (UE); allocating a plurality of discovery resources in response to the request; determining a timer for the plurality of discover resources; transmitting a message indicating the plurality of discovery resources and the timer for the plurality of discovery resources, the transmitted message configured to be used by a monitoring UE to determine which discovery resources to monitor; running an allocation timer on the first eNB concurrently with the timer being run on the monitoring UE; and transmitting a second message indicating that the plurality of discovery resources are no longer available in response to the allocation timer expiring.
