Title:
DATA TRANSMISSION METHOD AND NETWORK DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/027939
Kind Code:
A1
Abstract:
Provided is a data transmission method, comprising: according to a power ratio value of a neighbouring user device and a remote user device of two paired user devices, allocating a sending power to the neighbouring user device and the remote user device, wherein the power ratio value is a ratio value in a first ratio value set, at least one ratio value in the first ratio value set can be selected from a second ratio value set, and the second ratio value set is a set composed by power ratio values characterized by synthesized constellation points, with an interval being 1, selectable in a constellation graph; and performing data transmission according to the sending power of the neighbouring user device and the sending power of the remote user device. Therefore, the embodiments of the present invention can provide various power ratio values of a neighbouring user device and a remote user device of two paired user devices, so as to increase the flexibility of a base station to the neighbouring user device and the remote user device, and to facilitate improving performance gain which can be obtained by means of MUST transmission at the same time.
