Embodiment Construction

[0103] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0104] figure 1 It is a flow chart of the spectrum sharing method of the present invention, such as figure 1 shown, including:

[0105] Step 100: The transmission node determines the initial data transmission time and silent time within a preset time.

[0106] In this step, the transmission node is a transmission node in one of the transmission systems using the shared frequency spectrum, and this transmission system may be an LTE system.

[0107] In this step, it is assumed that the preset time is T1, the data transmission time is T2, and the silent time is T3, and T1=T2+...

Abstract

The invention discloses a frequency spectrum sharing method and a transmission node. The method comprises the steps in which, the transmission node determines an initial data transmission period and a silence period in a preset period; the transmission node transmits data on a shared frequency spectrum in the data transmission period, and detects resource utilization conditions on the shared frequency spectrum in the silence period; and the data transmission period and the silence period in a next preset period are adjusted based on the detected resource utilization conditions on the shared frequency spectrum. The invention can be used for solving the problem for an LTE system and other systems to coexist on the shared frequency spectrum, and achieves normal operation of the LTE on the shared frequency spectrum.

Description

technical field [0001] The invention relates to spectrum sharing technology, in particular to a spectrum sharing method and a transmission node. Background technique [0002] The Long Term Evolution (LTE) system is deployed and operated on licensed carriers. With the rapid growth of data services, the licensed spectrum will not be able to withstand the rapidly increasing data volume in the near future. Therefore, it is an important evolution direction of LTE development to deploy LTE in the shared spectrum and share the data traffic in the licensed carrier through the shared spectrum. [0003] Shared spectrum has the following characteristics: free / low cost; low access requirements and low cost, for example, individuals and enterprises can participate in the deployment, and the equipment of equipment manufacturers can be arbitrary; when multiple different systems operate in the shared spectrum, or the same system When different operators operate in the shared spectrum, som...
