Embodiment Construction

[0134] see figure 1 , figure 1 The first flow chart of a data transmission method provided by the embodiment of the present invention; in this embodiment, when the channel condition of the user is not ideal or is located at the edge of the cell, the relay node can be used to complete the communication with the base station Information transmission and exchange. In the process of transmission and exchange, it is understood as a voice conversation stage, and the relay node is Type I. To complete this process, the relay node performs network coding on the information sent by the user to the base station or the information sent by the base station to the user. The method includes:

[0135] Step 101: Receive a first data packet sent by a first user equipment on a first frequency, and receive a second data packet sent by a second user equipment on a second frequency;

[0136] That is to say, the relay node can receive different data packets sent by different users on different fr...

Abstract

The embodiment of the invention provides a data transmission method, a data transmission device, a relay node and a base station. The method comprises the following steps: receiving a first data packet which is sent by first user equipment at a first frequency and receiving a second data packet which is sent by second user equipment at a second frequency; carrying out network encoding on the first data packet and the second data packet to obtain encoded data packets; sending the encoded data packets to the base station at the first frequency or the second frequency. The technical problem in the prior art that the utilization rate of resources in the cooperative communication process is low is solved. The embodiment has the advantages that in the relay transmission process, frequency resources are saved, and the utilization rate of the resources is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method, device, relay node and base station. Background technique [0002] The wireless push-to-talk (PoC) service refers to the push-to-talk (PTT, Push-to-talk,) service in the public cellular mobile communication network, which is based on the multimedia subsystem (IMS, IP Multimedia Subsystem,) and through the semi-dual Work VoIP technology to achieve. PoC is a two-way multi-party communication method that allows a single user to communicate with other single users or a group of users. [0003] However, in the PoC service, if multiple users access and use the PoC service at the same time, they will interfere with each other and compete for resources, which not only increases the transmission delay of the PoC service for multiple users, but also reduces the resource utilization. [0004] In order to adapt to multi-user access and use PoC serv...
