Embodiment Construction

[0131] Before describing the solutions of the embodiments of the present invention, firstly, the concepts of resources and resource pools involved in the embodiments of the present invention will be described.

[0132] The D2D link sending resource pool (or resource) of the Remote UE is also called the Remote UE D2D link Tx resource pool (or resource), that is, the resource pool (or resource) of the D2D link Tx used by the Remote UE for UE-to-network relay , which is also the resource pool (or resource) of the D2D link Rx used by the Relay UE for UE-to-network relay;

[0133] The D2D link sending resource pool (or resource) of Relay UE is also called Relay UE D2D link Tx resource pool (or resource), that is, the resource pool (or resource) of D2D link Tx used by Relay UE for UE-to-network relay , which is also the resource pool (or resource) of the D2D link Rx used by the Remote UE for UE-to-network relay.

[0134] The pre-configured resource pools of out-of-coverage UEs incl...

Abstract

The invention discloses a method and device for instructing resource coordination . The method comprises steps of configuring a device-to-device (D2D) link resource pool for at least one remote user equipment (UE), wherein the configuration of the D2D link resource pool at least comprises time domain resource information, and resource of the D2D link resource pool is used for relay transmission from the UE to a network; informing, via a relay UE of the remote UE, the remote UE of the D2D link resource pool configured therefor. The configuration solution for the Remote UE D2D link Tx resource pool provided in the embodiment of the present application can effectively reduce resource allocation conflict in the UE-to-network relay, improving efficiency and reliability of the UE-to-network relay.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for indicating resource coordination. Background technique [0002] In the device-to-device (D2D) communication enhancement of Release 13 (Rel-13), it is proposed to support the communication method of UE-to-network relay, as follows figure 1 As shown, wherein the relay (Relay) node is also a user equipment (User Equipment, UE) supporting D2D communication. [0003] Wherein, the out-of-coverage (Remote) UE communicates with the evolved base station (eNB) through the relay node. [0004] The communication link between the Remote UE and the eNB is called a UE-to-network relay link, which is composed of a D2D link between the Remote UE and the Relay UE, and a cellular link between the Relay UE and the eNB. [0005] The resources used by the Remote UE for sending on the D2D link constitute a Remote UED2D link sending (Tx) resource pool. ...
