[0023] Such as figure 1 As shown, the first embodiment of the data transmission method of the present invention includes:

[0024] S11: Periodically detect the use of spectrum resources in the working frequency band to determine whether there are frequency point resources occupied by other services in the working frequency band;

[0025] Among them, other services are services authorized to use the working frequency band other than the preset business; the preset business can be a business of a certain industry among multiple industries sharing the working frequency band, or a certain business of a certain industry ; The working frequency band and detection cycle may be determined according to actual requirements, and are not specifically limited here.

[0026] Specifically, in an application example, the 223-235MHz frequency band is the working frequency band used by telemetry, remote control, data transmission and other services. In the application example, the default ser...

Abstract

The invention discloses a data transmission method, a device and a device with a storage function, wherein the method includes: periodically detecting the use of frequency spectrum resources in the working frequency band to determine whether there are frequency spectrum resources occupied by other services in the working frequency band; Point resources, if they exist, obtain discrete schedulable resource frequency bands, the schedulable resource frequency bands do not include occupied frequency point resources, and logically arrange the discrete schedulable resource frequency bands to form logically continuous schedulable spectrum resources, Data transmission is performed on the logically continuous schedulable spectrum resource, and the transmitted signal is processed by a filter, where the filter corresponds to the occupied frequency point resource. If it does not exist, all spectrum resources in the working frequency band are used for data transmission. Through the above method, the present invention can reduce the impact on data transmission on unscheduled spectrum resources and improve spectrum utilization.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method, device and device with storage function. Background technique [0002] In view of the fact that services in multiple industries share a spectrum resource, in order to coordinate the allocation of spectrum resources, there are two technical solutions in the prior art. One of the technical solutions is to use unscheduled services in other industries in a multi-carrier system. The way of occupying frequency resources avoids affecting the services of other industries; another technical solution is to divide the shared spectrum resources into equally spaced sub-bands, each sub-band has a guard frequency band, and uses carrier aggregation technology to divide multiple sub-bands After aggregation, it is allocated to the business use of an industry, thereby generating a larger transmission bandwidth and improving the transmission effect. [0003] In the first scheme...
