Embodiment 1

[0080] The present invention proposes a D2D resource pool configuration method, which is applied to D2D UE, such as figure 1 shown, including:

[0081] Step 101: The D2D UE receives the D2D resource pool configuration information of the base station;

[0082] Step 102: The D2D UE obtains D2D transmission resources from the D2D resource pool configuration information, and performs D2D transmission.

[0083] Here, the D2D resource pool configuration information includes one or a combination of the following: D2D resource pool information, D2D resource pool usage conditions, RRC status information, valid timer; wherein, the usage conditions and RRC status in the resource pool configuration information Can be used in combination.

[0084] Wherein, the D2D resource pool information includes: D2D discovery resource pool information, and / or D2D communication resource pool information, and / or D2D communication SA resource pool information, and / or D2D communication data resource pool...

Embodiment 2

[0112] The present invention proposes a D2D resource pool configuration method, which is applied to a base station, including: the base station sends out D2D resource pool configuration information; D2D UEs that receive the D2D resource pool configuration information obtain from the D2D resource pool configuration information D2D transmission resource, and perform D2D transmission.

[0113] Here, the D2D resource pool configuration information includes one or a combination of the following: D2D resource pool information, D2D resource pool usage conditions, RRC status information, and a valid timer.

[0114] Wherein, the D2D resource pool information includes: D2D discovery resource pool information, and / or D2D communication resource pool information, and / or D2D communication SA resource pool information, and / or D2D communication data resource pool information;

[0115] The conditions for using the D2D resource pool include: restricted use, or unrestricted use; the restricted u...

Embodiment 3

[0128] This embodiment describes the method that the system broadcast message sent by the base station includes the D2D resource pool configuration information of the D2D resource pool usage conditions, such as image 3 shown, including the following steps:

[0129] Step 301: The base station sends D2D resource pool configuration information through a system broadcast message (SIB); wherein, the D2D resource pool configuration information includes D2D resource pool information and D2D resource pool use conditions.

[0130] Here, the D2D resource pool information includes D2D discovery resource pool information and / or D2D communication resource pool information and / or D2D communication SA resource pool information and / or D2D communication data resource pool information; when the D2D resource pool usage condition is abnormal use or generic.

[0131] Step 302: The D2D UE in the IDLE state receives the SIB of the cell where it resides, and obtains the D2D resource pool configurat...

Abstract

The invention discloses a device-to-device D2D resource pool configuration method, device and system. The method comprises the following steps: receiving D2D resource pool configuration information of a base station by a D2D UE (User Equipment); and acquiring a D2D sending resource from the D2D resource pool configuration information by the D2D UE, and performing D2D transmission.

Description

technical field [0001] The present invention relates to network management technology in the communication field, and in particular to a D2D resource pool configuration method, device and system. Background technique [0002] With the development of wireless multimedia services, people's demand for high data rate and user experience is increasing, which puts forward higher requirements on the system capacity and coverage of traditional cellular networks. On the other hand, the popularity of applications such as social networks, short-distance data sharing, and local advertisements has gradually increased people's demand for understanding and communicating with nearby interested people or things (Proximity Services, Proximity Services). Traditional cell-based cellular networks have obvious limitations in terms of high data rates and proximity service support. In the context of this demand, D2D (Device-to-Device, device-to-device) represents a new direction for future communic...
