Abstract
Device-to-Device (D2D) resource configuration or allocation methods and apparatuses are provided. The D2D resource configuration method includes the following steps. A User Equipment (UE) receives D2D resource configuration information sent by a D2D control node. The UE configures D2D resources according to the D2D resource configuration information. The technical solution implements D2D resource configuration for a D2D UE.
Claims18
A Device-to-Device (D2D) resource configuration method, comprising:
- receiving, by a User Equipment (UE), a D2D indication, broadcasted by a D2D control node;
- sending, by the UE in response to receiving the D2D indication, a message containing D2D resource configuration request information to the D2D control node, wherein the D2D resource configuration request information comprises a D2D communication group identifier;
- receiving, by the UE, first D2D resource configuration information sent by the D2D control node to configure at least one resource allocation mode from a plurality of resource allocation modes for the UE, in response to the D2D resource configuration request information comprising the D2D communication group identifier, wherein the first D2D resource configuration information comprises D2D setup information corresponding to the at least one resource allocation mode;
- configuring, by the UE, D2D resources according to the at least one resource allocation mode of the D2D setup information in the first D2D resource configuration information;
- sending, by the UE, a message containing D2D resource release request information to the D2D control node;
- receiving, by the UE, second D2D resource configuration information sent by the D2D control node, wherein the second D2D resource configuration information comprises D2D release information corresponding to the at least one resource allocation mode;
- and
- releasing, by the UE, the D2D resources according to the second D2D resource configuration information.

A Device-to-Device (D2D) resource configuration apparatus, comprising:
- a receiving module configured to:
- receive a D2D indication, broadcasted by a D2D control node;
- receive first D2D resource configuration information sent by the D2D control node to configure at least one resource allocation mode from a plurality of resource allocation modes for the UE, in response to D2D resource configuration request information, wherein the first D2D resource configuration information comprises D2D setup information corresponding to the at least one resource allocation mode;
- and
- receive second D2D resource configuration information sent by the D2D control node, wherein the second D2D resource configuration information comprises D2D release information corresponding to the resource allocation mode;
- a sending module configured to:
- send, in response to receiving the D2D indication, a message containing the D2D resource configuration request information to the D2D control node, wherein the D2D resource configuration request information comprises a D2D communication group identifier;
- and
- send a message containing D2D resource release request information to the D2D control node;
- and
- a configuration module configured to:
- configure D2D resources according to the at least one resource allocation mode of the D2D setup information in the first D2D resource configuration information;
- and
- release the D2D resources according to the second D2D resource configuration information.
