Embodiment Construction

[0198] The existing technology does not take advantage of the differences in channel real-time characteristics, transmission link modes, and service types between terminals receiving data on the same frequency band, and provides time division multiplexing / statistical multiplexing between different frequency bands or between different antenna units. Use the technical scheme of the launch channel. In particular, there is no method given to utilize the difference in the maximum number of radio frequency channels that can be used by terminals at different geographic spatial locations in a multi-antenna system in a spatially multiplexed manner.

[0199] Specifically, the prior art does not provide a method for how to utilize the following resources in the above problems:

[0200] 1) Idle transmit channels during TDD uplink;

[0201] 2) During the downlink time slot of the TDD or FDD system, a part of the TDD transmission channel or FDD transmission channel determined by the rank o...

Abstract

The invention discloses a method and a system for time division multiplexing of transmitting channels to overcome the defect of lack of using transmitting channel redundancy in a multi-antenna system to reduce transmitting channels. The method includes: using a first group of transmitting channels on a first frequency band to transmit signals to a first geographic region through a first group of antenna units according to a first channel bandwidth in a first time interval; and using the first group of transmitting channels on a second frequency band to transmit signals in a second time interval after the first time interval, or using the first group of transmitting channels on a third group of antenna units to transmit signals, wherein the pass band width of the first channel is smaller than or equal to the width of the first frequency band, and the second frequency band is not identical to the first frequency band. By means of time division multiplexing of transmitting channels among different frequency bands and/or different antenna units, the defect of lack of using transmitting channel redundancy in the multi-antenna system to reduce the transmitting channels in the prior art is overcome.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for time-division multiplexing transmission channels. Background technique [0002] With the introduction of multiple-input multiple-output (Multiple-Input Multiple-Out-put, MIMO for short) technology and beamforming technology in the wireless communication system, the wireless access system becomes a multi-antenna system. With the introduction of spectrum aggregation technology, the wireless communication system has further evolved from a multi-antenna system to a multi-antenna multi-band (multi-carrier) system. [0003] The transmission channel is the most costly functional module in the wireless communication system. If the number of transmission channels configured in a multi-antenna and multi-band system can be reduced by time-division multiplexing the transmission channel without reducing system performance, the wireless communication system can be ...
