Data transmission control method, transceiver and system

Abstract

The invention relates to mobile communication technology, specially a data transmission control method in MIMO system, receiver and data transmission control system, the problem that simplifying H-ARQ mechanism in current technology and every emission antenna can be controlled at the same time is resolved. Said method includes: receiving end ensures the speed matching relationship of every emission antenna in corresponding TTI and feedback to the sending end; sending end ensures speed matching relationship of every emission antenna in next TTI and executes speed matching. And, the receiving end ensures average modulating mode or modulating mode of every emission antenna and feedback to the sending end; the sending end modulates data which is to be transmitted in next TTI based on the feedback modulating mode. A speed matching and executing module is connected with every emission antenna of said multi antenna receiver.

Description

Data transmission control method, transceiver and system Technical field The present invention relates to mobile communication technology, in particular to a data transmission control method, transceiver and data transmission control system in a MIMO multiple input multiple output system. Background technique The application of MIMO (Multi-Input Multi-Output) technology in wireless communication systems is receiving more and more attention. Whether it is from the perspective of increasing system capacity or improving system performance, MIMO is irreplaceable Superiority. In MIMO technology, in order to transmit data more effectively, the data rate of the transmitting end needs to be controlled. This requires the transmitting end to know some information of the channel through feedback, dynamically adjust the data rate, and even adjust the transmission rate of each transmitting antenna. At the same time, MIMO technology is usually combined with adaptive coding and modulation (...
