Management of device-to-device communication resources

A method comprising:

• assigning a first set of device-to-device (D2D) communication resources to a first D2D group and assign a second set of D2D communication resources to a second D2D group, the first D2D group comprising a first plurality of D2D user equipment (UE) devices performing public safety D2D communication, the second D2D group comprising a second plurality of D2D UE devices performing non-public safety D2D communication without performing public safety communication, 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;
• and
• 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 the service area of the base station to perform the public safety D2D communication.

A base station for providing wireless service within a service area comprising:

• a controller configured to assign a first set of device-to-device (D2D) communication resources to a first D2D group and assign a second set of D2D communication resources to a second D2D group, the first D2D group comprising a first plurality of D2D user equipment (UE) devices performing public safety D2D communication, the second D2D group comprising a second plurality of D2D UE devices performing non-public safety D2D communication without performing public safety communication, 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, wherein
• the controller is further configured to assign 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 the service area of the base station to perform the public safety D2D communication.
