Abstract

The embodiment of the present invention discloses a signal transmission method of a multi-user multiple-input multiple-output system, including: in the signal sending time slot, sending a signal to the user terminal on each antenna through a preset subcarrier; in the public information sending time slot In this method, the public information signal is sent to the user terminal on each antenna through preset subcarriers. The technical solution provided by the embodiment of the present invention can solve the problem of too long signal transmission delay of a multi-user multiple input and output system under a rapidly changing channel.

Description

technical field [0001] The invention relates to the communication field, in particular to a signal transmission method, base station and system of a multi-user multi-input and output system. Background technique [0002] Currently in the research process of 4G standard, Multiple Input Multiple Output system (Multiple Input Multiple Output, MIMO) technology has always been considered as a key technology, the introduction of multiple antennas enables the system to obtain higher diversity gain and multiplexing gain, thus The spectrum utilization rate, channel and system capacity of the communication system are greatly improved, and the MIMO system is divided into a single-user multiple input output system (Single-User MIMO, SU-MIMO) and a multi-user multiple input output system (Multi-User MIMO, MU-MIMO). In MU-MIMO, different user data can be sent in the same time-frequency resource block, which can increase the data transmission rate, but multiple users will also interfere w...
