Problems solved by technology

[0006] As for the symmetrical service, its uplink and downlink services are symmetrical, and the bandwidth of the uplink and downlink is also the same. It can be seen that it is very different from the asymmetrical service. Therefore, in the prior art Adaptive coding and modulation for asymmetric services is not suitable for symmetric services, so it is necessary to find a new technical solution to realize adaptive coding and modulation for symmetric services

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] In the adaptive modulation method, station and communication system provided by the embodiments of the present invention, during the process of adaptive modulation between the first station and the second station, the two stations respectively switch their current modulation modes to a unified modulation mode through communication negotiation model. By implementing the embodiment of the present invention, the first station and the second station can have the...

Abstract

The embodiment of the invention provides an adaptive modulation method, and a station and a communication system thereof. During the process of adaptive modulation of a first station and a second station, the two stations switch the current modulation modes of the two stations respectively to the unified modulate mode by means of communication negotiation. The adaptive modulation method enables the first station and the second station to have the same modulation mode and the same business rate while ensuring the communication quality, and achieves the effect of adaptive modulation in the symmetric business mode.

Description

technical field [0001] The invention relates to the communication field, in particular to an adaptive modulation method, a station and a communication system. Background technique [0002] The limited spectrum resource of mobile communication determines that the future mobile communication must adopt the anti-fading technology with high spectral efficiency to improve the performance of the system, so as to support the transmission of high-speed data and multimedia services. Adaptive Code and Modulation (ACM) can adjust the transmission parameters in real time according to the degree of channel fading. Change the transmission power, baud rate, coding structure, code rate, and modulation mode individually, or change the above-mentioned parameters comprehensively, under favorable channel conditions, to obtain greater throughput, and when the channel quality declines, correspondingly Reduce the transmission rate, and finally achieve the purpose of improving spectral efficiency,...
