Embodiment approach 1

[0094] Figure 9 It is a flowchart of a method for processing carrier resources of an unlicensed carrier according to a preferred embodiment of the present invention, as shown in Figure 9 As shown, the process includes the following steps:

[0095] Step S902, the LTE transmission node obtains the resource utilization and / or interference situation on the unlicensed spectrum in the corresponding detection window, and adjusts the length of the transmission window and / or the maximum reception window according to the resource utilization and / or interference situation on the unlicensed spectrum. Number of entries / maximum access time;

[0096] In step S904, the LTE transmission node accesses the unlicensed spectrum in a competitive manner within the transmission window, and the corresponding access times / access time is less than or equal to the maximum access times / maximum access time determined by the detection window.

Embodiment approach 2

[0098] This embodiment provides a specific implementation method for an LTE transmission node to adjust the length of the transmission window and / or the maximum number of access times / maximum access time according to the resource utilization and / or interference conditions on the unlicensed spectrum in the detection window corresponding to the transmission window ;

specific Embodiment 1

[0099] Figure 10 is a schematic diagram of the relationship between a detection window and a transmission window according to an embodiment of the present invention, as shown in Figure 10 As shown, transmission window 1 is the first window to be accessed, so the detection window corresponding to transmission window 1 is detection window 1, and the detection window corresponding to transmission window 2 is detection window 2, or the detection window corresponding to transmission window 2 is Detection window 1 and detection window 2, the detection window for detecting resource utilization is detection window 1 and detection window 2, and the detection window for detecting interference is detection window 2;

[0100] The detection window corresponding to transmission window 3 is detection window 3, or the detection windows corresponding to transmission window 3 are detection window 1, detection window 2 and detection window 3, or the detection windows corresponding to transmiss...

Abstract

The invention discloses a carrier wave resource processing method and device of unauthorized carrier waves and a transmission node. The method comprises that an access unauthorized carrier wave is determined via competition in a transmission window; and according to a predetermined access condition, the unauthorized carrier wave is accessed, and the predetermined access condition comprises at least one selected from the determined length of the transmission window, the maximal access frequency in the transmission window and the maximal access time in the transmission window. The problem that a system coexists with other systems when working in the unauthorized carrier wave in the related art is solved, the system coexists with the other systems fairly in the unauthorized carrier wave, idle resource of the unauthorized carrier wave is utilized fully, and the utilization rate of the unauthorized carrier wave is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a carrier resource processing method, device and transmission node of an unlicensed carrier. Background technique [0002] Up to now, it is well known that Long-Term Evolution (LTE for short) is deployed and operated on licensed carriers. However, with the rapid growth of data services, in the near future, licensed spectrum will no longer be able to bear such a huge amount of data. Therefore, deploying LTE in the unlicensed spectrum and sharing the data traffic in the licensed carrier through the unlicensed spectrum is an important evolution direction of the subsequent LTE development. [0003] In addition, there are also many advantages for unlicensed spectrum: free / low cost (no need to purchase unlicensed spectrum, and the cost of spectrum resources is zero). Low access requirements and low cost (individuals and enterprises can participate in the deployment, and equipment v...
