Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] For the relevant content involved in the embodiments of the present invention, the following explanations are provided:

[0052]The base station, that is, the public mobile communication base station, refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication switching center in a certain radio coverage area. The coverage area of ​​a base station is called a cell. One base station can cover one or more cells, one cell can have one or more adjacent cells, and the base stations corresponding to a cell and its adjacent cells can be different.

[0053] figure 1 It is a flowchart of a data transmission method provided by an embodiment of the present invention. This...

Abstract

An embodiment of the invention provides a data transmission method, a device, and a base station, and relates to the technology field of communication. The method comprises determining the region where a user device permitting data transmission is in a service cell; when the user device is at the edge of the service cell, performing single stream data transmission with the user device. Via determining the region where the user device permitting data transmission is in the service cell, and performing single stream data transmission with the user device when the user device is at the edge of the service cell, obtaining of SINR of each data stream is prevented, massive calculation via a single-stream or multi-stream self-adaptive switching algorithm upon each user device is prevented, calculated amount is reduced, calculated complex is reduced, and frequent switching between a single-stream transmission mode and a multi-stream transmission mode is prevented.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a data transmission method, device and base station. Background technique [0002] MIMO (Multiple Input Multiple Output) technology uses multiple antennas at the transmitting end to send signals independently, and at the same time uses multiple antennas at the receiving end to receive and restore the original signal, which can increase the coverage of the wireless system and improve throughput. MIMO technology can be divided into SU-MIMO (Single User-Multiple Input Multiple Output) mode and MU-MIMO (Multiple User-Multiple Input Multiple Output) mode. [0003] Among them, in order to improve the throughput, for the downlink communication in the SU-MIMO mode, the base station can send a data stream to a single user equipment within a certain time and frequency resource, and can also send multiple data streams to a single user equipment; For uplink communication in SU-MIMO m...
