Problems solved by technology

[0028] Channel modeling must be considered when using LSTC to transmit information. However, most of the channel models involved in the prior art assume that the channels between the antennas are not correlated with each other, which does not conform to the actual radio wave transmission.
Therefore, the biggest difficulty in applying the prior art LSTC to practice is that efficient decoding methods, such as the V-BLAST decoding method, will fail when there is LOS (Line of Sight, Line of Sight) transmission between the receiving antenna and the transmitting antenna, because At this time, there is a direct path of electromagnetic waves between the transmitting and receiving antennas, and the channel matrix H does not meet the condition of full rank, so that the existing decoding method of V-BLAST cannot be implemented

Embodiment Construction

[0088] The main idea and innovation of the present invention are that the control signaling and service information between the mobile station and the base station are transmitted using their own codec methods; wherein the transmission of service information includes at least two modes; firstly, the mobile station is judged during communication. The transmission state between the base station and the base station, and then the control signaling controls the transmission of service information in a mode corresponding to the transmission state. Doing so can overcome the strict requirements of a single transmission mode on the channel characteristics, and more effectively ensure the continuity of communication.

[0089] Here, a preferred transmission mode of the control signaling between the mobile station and the base station is to use space-time coding, because its coding and decoding are simple and are not affected by channel line-of-sight conditions. The transmission mode of ...

Abstract

This invention relates to a MIMO mobile communication method , in which, th control signaling and service information between a mobile station and a base station transmit information with their own coding modes, and the transmission of service information includes at least two modes and transmission state between the mobile station and the base station is judged in communication and then the control signaling controls the service information to transmit it in the mode corresponding to the transmission state. This invention also provides a MIMO mobile communication system.

Description

technical field [0001] The present invention relates to the field of mobile communication, more specifically, to a MIMO mobile communication method and system. Background technique [0002] MIMO (Multiple-Input Multiple-Output) technology is equipped with multiple antenna units at the transmitting end and receiving end of the communication link to form an antenna matrix, which provides space multiplexing gain and space diversity gain for the system. In order to ensure the performance in MIMO transmission, corresponding channel coding must be adopted. For this reason, Space-Time Code STC (Space-Time Code) is proposed. [0003] Schematic diagram of the structure of the STC transmitter figure 1 shown. The input bit stream is first channel coded by the channel coder 101, the coded signal is interleaved by the interleaver 102, then space-time coded by the space-time coder 103, and finally processed by the radio frequency processors 104 and 105, and then each branch The signal ...
