Pre-Emption and Resource Allocation Prioritization for D2D Communications

摘要

A network node assigns resources for use in wireless communication based on priority. The network node receives, from a wireless communication device, a service request message that requests connection of a communication session. The network node determines a priority level for the requested communication session. The priority level comprises a cellular layer admission priority of whether the network node can preempt cellular resources of an existing communication session in order to admit the requested communication session on the cellular layer, and a device-to-device (D2D) layer admission priority of whether the network node can preempt D2D resources of an existing communication session in order to admit the requested communication session on the D2D layer. The network node assigns resources based at least in part on the priority level. The resources are used for D2D communication or cellular communication.

主权项

1. A network node for wireless communication between a wireless communication device and a network operable to assign resources for use in wireless communication, whereby the network node is operable to:
receive, from a wireless communication device, a service request message that requests connection of a communication session; characterized in that the network node is further operable to determine a priority level for the requested communication session, the priority level comprising:
a cellular layer admission priority of whether the network node can preempt cellular resources of an existing communication session in order to admit the requested communication session on the cellular layer; anda device-to-device (D2D) layer admission priority of whether the network node can preempt D2D resources of an existing communication session in order to admit the requested communication session on the D2D layer; and assign resources based at least in part on the priority level, wherein the resources are used for D2D communication or cellular communication.
