Abstract
Official abstract text for this publication.
Device-to-device (D2D) communication is one alternative to communication between devices through a radio access network. One interesting D2D communication method is reuse-mode D2D, where D2D nodes communicate with each other using the same uplink (UL) radio resource that is being used by some other cellular user equipment(s) (UEs). In other words, the UL cellular resources occupied by cellular UEs are reused by D2D nodes in their short-range communications. Centralized control of D2D communication can be performed by appropriate signaling between a D2D-capable UE and an evolved Node B (eNB).
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: determining whether to grant reuse resources, comprising resources currently being used for a cellular connection, to a device-to-device connection based on reviewing by priority at least one request for device-to-device connection resources, wherein the reuse resources comprise at least one uplink channel to be used by a user equipment during a time period; and initiating transmission of a notification of device-to-device reusable re…
