Example Embodiment

[0162] Preferred embodiment one

[0163] In this preferred embodiment, a process for the base station and the UE to select a resource pool based on the UED2D service quality information is provided. The following will further elaborate on specific example 1 and specific example 2.

Example Embodiment

[0164] Example 1

[0165] In a public safety scenario, Officers A, B, C, and D use public safety UE1, UE2, UE3, and UE4 with D2D functions. Officer A, B, C, and D are all subscribed to public safety services, and UE1, UE2, and UE3 are all configured to belong to D2D communication group X.

[0166] At the rescue location, OfficerA hopes to initiate a multicast call to inform other officers corresponding to the D2D communication group X in the vicinity. Figure 5 It is a configuration flow chart of obtaining D2D service quality information of user equipment and obtaining D2D resource pool through dedicated signaling in Example 1 of the preferred embodiment of the present invention. Such as Figure 5 As shown, the process can include the following processing steps:

[0167] Step S502: UE1 of OfficerA first needs to access the network, and obtain user equipment priority and / or D2D communication group priority to which the user equipment belongs, user equipment type and / or D2D communicat...

Example Embodiment

[0172] Example 2

[0173] In the commercial application scenario, Mary and John hold UE1 and UE2 with D2D discovery function. UE1 and UE2 are within the D2D discovery range of each other. Image 6 It is a flow chart of obtaining D2D resource pool configuration by the user equipment of Example 2 in the first preferred embodiment of the present invention through broadcast signaling. Such as Image 6 As shown, the process can include the following processing steps:

[0174] Step S602: If the UE1 and UE2 in the idle state need to perform D2D discovery, they first need to monitor whether the camping cell broadcasts D2D transmission resource pool information. It is assumed that the eNB corresponding to the resident cell broadcasts and transmits the resource pool information corresponding to the first resource allocation mode. If there are multiple resource pools corresponding to the first resource allocation method, eNB1 can divide different attributes according to user equipment prior...

Abstract

The invention discloses a resource acquisition method, a resource acquisition device, a resource configuration method, a resource configuration device, a resource pool configuration method and a resource pool configuration device. The resource acquisition method includes the step that a source node sends an information set corresponding to the quality of 2D2 services of UE to a target node, wherein the information set is used for the target node to configure/allocate D2D resources and/or modulation and coding schemes for the UE. With the methods and devices provided by the technical schemes of the invention adopted, D2D resources can be allocated or configured for the UE quickly and flexibly, and smooth D2D transmission can be ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a resource acquisition and configuration method and device, and a resource pool configuration method and device. Background technique [0002] With the rapid development of wireless multimedia services, people's demand for high data rate and user experience is increasing, which puts forward higher requirements for the system capacity and coverage of traditional cellular networks. On the other hand, application scenarios such as public safety, social networking, short-distance data sharing, and local advertising have gradually increased people's demand for understanding and communicating with nearby people or things, that is, proximity services (ProximityServices). The traditional base station-centric cellular network has obvious limitations in high data rate and proximity service support. Against this background of demand, Device-to-Device (Device-to-Device, Referred to as D2D...
