FREQUENCY BAND UTILIZATION METHOD AND DEVICE

摘要

Embodiments of the present invention disclose a frequency band utilization method and device, for use in the field of communications, so as to solve the problem that frequency band resources are seriously wasted because existing protection frequency bands must be completely idle. The method comprises: a first device configuring a first frequency band to be a main carrier of carrier aggregation (CA); and the first device configuring a second frequency band to be an auxiliary carrier of CA, the second frequency band being a protection frequency band between a TDD network and a second network, the first device being a device of the time division duplex (TDD) network, and frequency bands of the TDD network comprising the first frequency band. The embodiments of the present invention apply to frequency band utilization.
