Embodiment Construction

[0199] 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.

[0200] Specifically, the prior art does not provide a method for how to utilize the following resources in the above problems:

[0201] 1) Idle transmit channels during TDD uplink;

[0202] 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 system for time division multiplexing of transmission channels, which overcomes the current shortcoming that there is no provision to reduce the number of transmission channels by utilizing the transmission channel redundancy existing in a multi-antenna system. The method includes: within a first time interval transmit signals to a first geographical area using a first set of transmit channels at a first channel bandwidth on a first frequency band through a first set of antenna elements; and using the first set of transmit channels on a second frequency band during a second time interval following the first time interval Transmit channel, or use the first group of transmit channels to transmit signals on the third group of antenna units; the passband width of the first channel is less than or equal to the width of the first frequency band within the first time interval, and the second frequency band is the first frequency band outside the frequency band. Embodiments of the present invention overcome the shortcomings of the prior art that do not provide for reducing the number of transmission channels by utilizing the redundancy of transmission channels existing in multi-antenna systems by time-division multiplexing transmission channels between different frequency bands and / or between different antenna units. .

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 ...
