Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

[0055] In the related art, in the development process of the wireless communication system, for the unlicensed spectrum, in 3GPP, it is proposed to use the unlicensed frequency band through the LAA (license assisted access) mechanism. That is to say, the licensed frequency band is used to assist the use of the unlicensed frequency band. In order to ensure the coexistence with other systems such as WiFi on the unlicensed frequency band, a me...

Abstract

The embodiment of the invention relates to a contention window length determination method. The method comprises the following steps of: determining a target bandwidth part after a sending end switches the bandwidth part in an unlicensed frequency band; and determining the target contention window length corresponding to the target bandwidth part according to the incidence relation between the frequency domain information of the bandwidth part and the contention window length. According to the embodiment of the invention, the communication conditions of different bandwidth parts are different.The incidence relation between the frequency domain information of the bandwidth part and the length of the contention window can be respectively determined by the base station aiming at different bandwidth parts, so that the contention window length corresponding to each bandwidth part under different communication conditions can be reflected relatively accurately, the target contention window length corresponding to the target bandwidth part is determined, the target contention window length can be suitable for the target bandwidth part, the accuracy of performing LBT on the target bandwidth part according to the target contention window length can be ensured, and good communication quality can be achieved after the target bandwidth part is occupied.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a method for determining a contention window length, a device for determining a contention window length, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of communication technology, the communication between the terminal and the base station is not limited to the licensed frequency band, but also can communicate in the unlicensed frequency band. For example, the continuous emergence of new Internet applications such as the new generation of AR / VR and vehicle-to-vehicle communication has put forward higher requirements for wireless communication technology, driving the continuous evolution of wireless communication technology to meet the needs of applications. [0003] At present, cellular mobile communication technology is in the evolution stage of a new generation of technology. An important ...
