Abstract

The embodiment of the present invention discloses a coordinated scheduling method, which is used to avoid spectrum interference generated when only FDD spectrum and TDD spectrum of the same standard frequency band are aggregated. The method in the embodiment of the present invention includes: the base station determines the frequency band of the first preset bandwidth in the time division duplex TDD frequency band as the primary component carrier; the base station determines the frequency band of the second preset bandwidth in the frequency division duplex FDD frequency band as the secondary component carrier, The FDD frequency band and the TDD frequency band belong to the same standard frequency band; the base station aggregates the primary component carrier and the secondary component carrier; when the primary component carrier is in downlink scheduling, the base station schedules the secondary component carrier corresponding downlink subframe. The embodiment of the present invention also provides a base station. The embodiments of the present invention can effectively avoid spectrum interference generated when only the FDD spectrum and the TDD spectrum of the same standard frequency band are aggregated.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for coordinated scheduling and a base station. Background technique [0002] With the development of mobile communication technology, users have higher and higher requirements on data rate, and at the same time, the problem of shortage of spectrum resources is becoming more and more serious. In order to meet the bandwidth requirements of the LTE-Advanced (Long Term Evolution Advanced) system, a Carrier Aggregation (CA, Carrier Aggregation) technology is proposed. Compared with the LTE system, the LTE-Advanced system needs to make corresponding changes in many aspects such as uplink and downlink control channel design and power control to support the function of carrier aggregation. [0003] Carrier aggregation has been developed from scratch in the LTE (Long Term Evolution) standard defined by the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Pro...
