Problems solved by technology

[0003] Due to the differences in transmission power and coverage area of ​​different systems, and the isolation relationship between different systems in deployment space, the guard bands set in spectrum planning for coexistence between systems or frequency bands may be further utilized. However, The existing use of guard bands has the disadvantage of insufficient use or poor use flexibility

Abstract

The invention discloses a protection frequency band use method and a radio device. The method includes using a continuous passband of a first radio frequency filter to cover at least a part of a protection frequency band; configuring a control channel on a first frequency band adjacent to the protection frequency band or a second frequency band not adjacent to the protection band so as to use the protection frequency band through the control channel, wherein the first frequency band is used in a shared manner through at least one way among frequency division, time division and code division by the control channel of a first radio device and a control channel of a macro base station having network coverage relation with the first radio device. The second frequency band is used in a shared manner through at least one way among frequency division, time division and code division by the control channel of the first radio device and the control channel of the macro base station having network coverage relation with the first radio device. In another embodiment, the second frequency band is used by the control channel and a service channel used for micro cell coverage of the first radio device.

Description

technical field [0001] The invention relates to the technical field of radio communication, in particular to a method for using a guard frequency band and a radio device. Background technique [0002] In order to achieve coexistence between wireless communication systems, guard bands are set between different frequency bands or between different channels of the same frequency band. The guard bands set between planned or divided different frequency bands are also called inter-band protection. Frequency band, the guard frequency band set between the system working frequency bands of different operators in the same frequency band is also called the guard frequency band between systems in the frequency band, and the frequency band reserved on different transmission channel sides in the frequency band of the same operator is also called is an intra-frequency channel guard band; usually, an inter-band guard band is also an inter-system guard band, and an intra-frequency channel gu...
