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

A method for time-division multiplexing an emission channel. Within a first time interval, a first set of emission channels is used on a first frequency band to emit a signal using a first emission bandwidth to a first geographic area via a first set of antenna units; within a second time interval subsequent to the first time interval, the first set of emission channels is used on a second frequency band; or, the first set of emission channels is used on a third set of antenna units to emit the signal; where the first emission bandwidth within the first time interval is less than or equal to the width of the first frequency band, and the second frequency band is a frequency band other than the first frequency band. Also disclosed is a corresponding system for multiplexing the emission channel. The present application allows for flexible configuration between different technical specifications, greatly reduced basic configuration of emission channel number for system, and greatly reduced costs of network building.

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 ...
