Abstract

The invention provides a method for providing large transmission bandwidth for a long-term evolution multi-carrier system, which comprises the following steps that: a base station sends data through an aggregation frequency range of the long-term evolution multi-carrier system; a first guard band is inserted between effective transmission bandwidths of physical layers of two adjacent LTE frequency ranges to make the center of the effective transmission bandwidths of the physical layers of the LTE frequency ranges be on a channel raster; the first guard band is not available to an LTE terminal; the first guard band is available to terminals of the long-term evolution multi-carrier system, and schedules resources of the first guard band for the long-term evolution multi-carrier system only when the terminals working on the effective transmission bandwidths of the physical layers of at least two adjacent LTE frequency ranges are the terminals of the long-term evolution multi-carrier system in a predetermined time slot; and the terminals receive the data on the aggregation frequency range of the long-term evolution multi-carrier system according to the capacity per se. The method can fully use frequency resources as much as possible on the basis of ensuring backward compatibility and providing adequate frequency guard band.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, system and device for providing large transmission bandwidth for long-term evolution multi-carrier systems. Background technique [0002] In the long-term evolution broadband mobile communication system, such as LTE-Advanced or IMT-Advanced system, it is necessary to provide a higher peak rate through a larger transmission bandwidth to meet the needs of users, but the expansion of the transmission bandwidth is limited by the operator's own frequency resources. Since operators have limited frequency resources, in order to meet the bandwidth requirements of the LTE-A system, multiple continuous or discontinuous LTE frequency bands need to be aggregated, and the maximum bandwidth of each frequency band is consistent with the bandwidth of the current LTE system. That is 20MHz. In addition, since the LTE-A system needs to maintain good backward compatibili...
