Abstract

The invention discloses a resource dispatching method based on a carrier weight in a multi-carrier system, which mainly solves problems that system performance and complicatedness are hard to be both taken into account and an LTE (Long Term Evolution) user and cell edge user are limited in performance in the prior art. The method comprises the following realizing steps: obtaining user information and carrier information through a base station end and setting maximum accessible carrier number of each user; figuring out a carrier coverage weight factor and a user type weight factor according to the user and the carrier information so as to obtain a carrier weight factor of the user; figuring out user priority according to the carrier weight factor of the user and using the carrier weight factor as one factor in a priority calculating formula; and distributing resources to the user according to a user priority sequence so as to finish resource dispatching. According to the invention, the complicatedness of the system is reduced and the performances of the cell edge user and the LTE user in the system are improved on the premise that the throughput is guaranteed; and the resource dispatching method can be used for resource dispatching in an LTE-Advanced carrier polymerization system.

Description

technical field [0001] The invention belongs to the field of wireless communication, relates to resource scheduling technology, in particular to a resource scheduling method based on carrier weight in a multi-carrier system, which can be used for resource scheduling in an LTE-Advanced carrier aggregation system. Background technique [0002] With the development of mobile communication technology, it is difficult for the third-generation mobile communication system to fully meet the needs of users. In order to meet the new requirements of IMT-Advanced in terms of frequency, bandwidth, peak rate and compatibility, 3GPP is in the long-term evolution of LTE. On the basis of further evolution, an evolved version of LTE is proposed: LTE-Advanced. [0003] The requirements analysis of the LTE-Advanced system points out that in order to achieve the peak rate of 1Gb / s, a maximum bandwidth of 100MHz is required. It is difficult to find such a wide bandwidth in the existing spectrum r...
