Method, system and equipment for transmitting and receiving data

Abstract

The present application relates to the technical field of wireless communications, and particularly to a method, system and device for sending and receiving data, which are used for solving the problem existing in the prior art that the detection success rate is relatively low due to the fact that a UE at a receiving end cannot detect signals on a plurality of transmission resources sent by a UE at a transmitting end after combing same. The method of the present application comprises: determining, by a transmitting end, a first transmission resource used for conducting data transmission, and determining a second transmission resource from a second transmission resource pool corresponding to the first transmission resource; and sending data to be transmitted through the first transmission resource and the second transmission resource. Since the receiving end can receive data information on a first transmission resource and a second transmission resource related to the first transmission resource, it is guaranteed that the receiving end can detect signals on a plurality of transmission resources sent by a UE at a transmitting end after combing same, thereby improving the detection success rate and further improving the transmission performance.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for sending and receiving data. Background technique [0002] In traditional cellular communication technology, the data communication process between two user equipments is as follows: figure 1 shown. The voice and data services of the two user equipments interact through the eNB (evolved base station) where they reside and the core network. [0003] D2D (Device-to-Device), that is, user equipment direct technology, refers to the way that adjacent user equipment can transmit data through a direct link within a short distance without forwarding through a central node (ie, a base station). Such as figure 2 shown. The short-distance communication characteristics and direct communication mode of D2D technology make it have the following advantages: [0004] The user equipment short-distance direct communication method can a...
