A method, system and device for sending and receiving data

Abstract

The embodiments of the present invention relate to the technical field of wireless communication, and in particular to a method, system, and device for sending and receiving data, so as to solve the problems existing in the prior art on multiple transmission resources that the UE at the receiving end cannot transmit to the UE at the transmitting end. The signals are combined and detected, which makes the detection success rate relatively low. The method in the embodiment of the present invention includes: the transmitting end determines a first transmission resource for data transmission, and determines a second transmission resource from a second transmission resource pool corresponding to the first transmission resource; through the first transmission resource A transmission resource and the second transmission resource are used to send data to be transmitted. Since the receiving end can receive data information on the first transmission resource and the second transmission resource associated with the first transmission resource, it is ensured that the receiving end can perform combined detection on the signals on multiple transmission resources transmitted by the UE at the transmitting end, thereby improving The detection success rate is improved, and the transmission performance is further improved.

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. Services such as voice and data of the two user equipments interact through their respective eNBs (evolved base stations) and core networks. [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 ach...
