Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] The invention provides a spectrum utilization method, a spectrum utilization device, and a communication system with an improved spectrum utilization manner.

[0034] FIG. 6 shows a flow chart of a method for using spectrum according to the present invention, which includes the following steps:

[0035] Step S602, exclusively select part of the frequency bands from the communication licensed frequency bands of the wireless duplex communication system as supporting frequency bands

[0036] Step S604, dynamically select some idle frequency bands from other frequency bands as dynamic borrowed frequency bands, wherein the dynamically borrowed frequency bands support time division duplexing, and can be used for both uplink transmission and downlink transmission; and

[0037] In step S606, the supporting frequency band and the dyna...

Abstract

The present invention provides a method for using the frequency spectrum, which belongs to the frequency spectrum using of the wireless duplex communication system, and the method comprises the following steps: selecting part frequency band from the communication permissive frequency band of the wireless duplex communication system as the supporting frequency band; dynamically selecting part-free frequency band from other frequency band as the dynamic borrowed frequency band, wherein, the dynamic borrowed frequency band supports the time division duplexing mode, not only can be used in the upgoing transmission but also can be used in the downgoing transmission; and composing the supporting frequency band and the dynamic borrowed frequency band to the frequency spectrum which is needed by the wireless duplex communication system with the mode of frequency division or half-frequency division. The invention also provides a frequency spectrum using device.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method and a device for using spectrum using a communication licensed frequency band and a dynamically borrowed frequency band. Background technique [0002] Spectrum resources are limited. With the continuous growth of wireless communication service requirements, the demand for spectrum is increasing, resulting in increasingly scarce available spectrum resources, and it is becoming more and more difficult to plan and allocate communication spectrum. [0003] The traditional spectrum usage method is to allocate fixed working frequency bands to different types of systems in order to ensure the spectrum required by the communication system and ensure that different systems work without interference. The spectrum allocated to a certain type of communication system is only allowed to be used by this type of system. Other systems cannot be used. According to the d...
