Problems solved by technology

[0005] If the LAA base station adopts the contention parameters corresponding to the service with higher priority, and does not expand the backoff window after receiving NACK, this is beneficial for LAA to seize the license-free frequency band, but it is unfair to other access technologies (such as Wi-Fi) , and will also lead to an increased probability ...

Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] see figure 1 It shows a schematic flowchart of a method for generating a contention parameter of an unlicensed channel disclosed by an embodiment of the present invention.

[0054] Depend on figure 1 It can be seen that the method includes:

[0055] S11: Determine whether the LAA base station is currently competing for a channel.

[0056] It should be noted that the deployment of LTE in the license-free frequency band must be based on the principle o...

Abstract

The invention discloses an unlicensed channel competition parameter generation method and a device. When an LAA base station does not compete a channel at present and has no need to transmit a discovery reference signal, the method and device generate a present competition parameter of the LAA base station by utilizing competition parameters corresponding to to-be-dispatched businesses and weight of the to-be-dispatched businesses. According to the invention, according to comprehensively considering the different competition parameters corresponding to the to-be-dispatched businesses data of LTE on an unlicensed frequency band, the method and the device generates a competition parameter of the base station competing the unlicensed frequency band, on one side, a problem that the LTE always using relatively good competition parameter to compete the channel, which is unfair for other access technologies, is avoided, on the other side, different priority business requirements are considered, so that influence on delay-sensitive business is avoided.

Description

technical field [0001] The present application relates to the field of communication technologies, and more specifically, to a method and device for generating contention parameters of an unlicensed channel. Background technique [0002] With the rapid development of mobile smart devices, the rapid emergence of high-definition multimedia streaming services, and the penetration of the Internet into all walks of life, etc., the traffic of mobile data services has exploded, and the existing licensed frequency bands are not enough to provide sufficient network capacity. Meet user needs. Offloading data services to unlicensed frequency bands (such as 5GHz) can relieve network pressure. How to use unlicensed spectrum resources with the assistance of licensed spectrum has become one of the important research topics of 3GPP. [0003] Usually, technologies in licensed frequency bands, such as LTE (Long Term Evolution, long-term evolution) are not suitable for use in unlicensed frequ...
