Management of device-to-device communication resources
First Claim
1. A method comprising:
- identifying a first device-to-device (D2D) group comprising a first plurality of D2D user equipment (UE) devices performing public safety D2D communication;
identifying a second D2D group comprising a second plurality of D2D UE devices performing non-public safety D2D communication without performing public safety D2D communication;
assigning a first set of D2D communication resources to the first D2D group and assigning a second set of D2D communication resources to the second D2D group, the D2D communication resources of the first set being different from the D2D communication resources of the second set, the first set of D2D communication resources and the second set of D2D communication resources being subsets of reserved D2D communication resources which are a subset of defined uplink communication resources defined by a communication specification for uplink communication between the D2D UE devices and a base station;
assigning D2D communication resources reserved for out-of-coverage (OoC) D2D communication to be used by at least one of the first plurality of D2D UE devices when the at least one of the first plurality of D2D UE devices is located within a service area of the base station to perform the public safety D2D communication; and
assigning the D2D communication resources reserved for out-of-coverage (OoC) D2D communication to be used by at least one of the second plurality of D2D UE devices.

Abstract
A base station assigns a first set of device-to-device (D2D) communication resources to a first D2D group and assigns a second set of D2D communication resources to a second D2D group. The D2D communication resources of the first set are different from the D2D communication resources of the second set. The first set of D2D communication resources and the second set of D2D communication resources are subsets of reserved D2D communication resources which are a subset of defined uplink communication resources defined by a communication specification for uplink communication between the D2D UE devices and a base station where the reserved D2D communication resources not used for uplink transmission to the base station.
