Embodiment Construction

[0119] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0120] Such as Figure 4 As shown, in the embodiment of the present invention, the detailed method flow of the receiving end UE performing data reception in D2D communication is as follows:

[0121] Step 401: The UE at the receiving end detects the control information sent by the sending end by using the locally saved configuration information of each resource pool.

[0122] In the embodiment of the present invention, the UE at the rec...

Abstract

The invention discloses a data receiving method and a data sending method in communication between equipment, and equipment, and aims to provide a solution for determining how to receive data of opposite UE in the event that UE does not determine which resource pool configuration information is adopted by the opposite UE. The method comprises the following steps: detecting control information sent by a sending end by adopting each locally stored resource pool configuration information; determining resource pool configuration information adopted by the sending end according to the detected control information; and receiving data information of the sending end according to the determined resource pool configuration information and the control information.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a data receiving method, a sending method and a device in Device to Device (Device to Device, D2D) communication. Background technique [0002] In traditional cellular communication technology, the data communication process between two terminals is as follows: figure 1 As shown, services such as voice and data between two terminals are interacted through the base stations (ordinary base stations or evolved base stations) where they reside and the core network. [0003] D2D communication, that is, terminal direct technology, means that adjacent terminals (UEs) can transmit data through direct links within a short distance without central node (such as base station) forwarding, such as figure 2 shown. [0004] D2D communication has the following advantages: [0005] 1. The terminal short-distance direct communication method can achieve higher data transmissi...
