Embodiment Construction

[0042] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can also be realized.

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0044] The first embodiment of the present invention relates to a method for configuring a transmission frequency band by a base station, the process of which is as follows figure 2 shown.

[0045] In step 201, the base station configures a main transmission frequency band. The main transmission frequency band includes the main control fre...

Abstract

The invention relates to the field of wireless communication, and discloses a method and a device for collocating and selecting a transmission frequency band. In the method and the device, a total system bandwidth is firstly marked off a main transmission frequency band as a transmission bandwidth keeping compatible with the prior system, other frequency bands positioned in the total system bandwidth beyond the main transmission frequency band have no fixed bandwidth division, but other transmission frequency bands beyond the main transmission frequency band are gradually distributed as auxiliary transmission frequency bands according to the running condition of the system and the requirement. The variable auxiliary transmission frequency bands enable the system to adapt to the requirement of service change more flexibly.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the configuration and selection technology of the transmission frequency band. Background technique [0002] In an existing wireless mobile communication system, the system frequency band is divided into multiple frequency bands in advance, and the bandwidth of each frequency band is fixed. For example, in communication systems such as Long Term Evolution ("LTE"), the system can have multiple bandwidth configurations, such as 20MHz, 10MHz, 5MHz, etc.; at the same time, the allocation of these bandwidths is also static, that is, once Select the bandwidth configuration, and the work of the whole system is fixed on this bandwidth; both the base station and the terminal must have the ability to send and receive on this bandwidth. [0003] figure 1 A schematic diagram of a bandwidth static allocation scheme in the prior art is given. Such as figure 1 As shown in (a), the tota...
