Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular, to a method, apparatus, device, and storage medium for accessing an unlicensed channel. Background Art

[0002] Radio spectrum resources are limited and non-renewable natural resources. Therefore, each country has a special management agency for radio spectrum and issues special policies and regulations to achieve unified planning and management of radio spectrum. Currently, most countries' spectrum management adopts a fixed spectrum allocation strategy, that is, spectrum resources are managed by the government's competent department and allocated to fixed licensed users, which can ensure that excessive mutual interference is avoided among users and spectrum resources are better utilized. Currently, spectrum resources can be divided into two categories, namely licensed spectrum and unlicensed spectrum.

[0003] Licensed spectrum is strictly restricted and protected, and only licensed users and their compliant devices are allowed to access.

[0004] Unlicensed frequency band resources are abundant. However, in order to ensure fair coexistence among different radio access technologies (RATs) using this frequency band, a listen before talk (LBT) technology based on clear channel assessment (CCA) is introduced. Introducing LBT into the new radio based unlicensed access (NR-U) of the unlicensed frequency band is an important way to ensure fair coexistence. Summary of the Invention

[0057] The embodiments of the present disclosure will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0058] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the embodiments of the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0059] The sender device can use the LBT mechanism, also known as the access method that performs LBT detection. Specifically, the sender device first performs LBT and then accesses the unauthorized channel.

[0060] Since the signal attenuation of the high-frequency channel is relatively large, after the sender device accesses the high-frequency unauthorized channel, even if the distance between the sender devices is relatively close, the interference between the sender devices may be relatively small. Therefore, the no-LBT mechanism is proposed, also known as the access method that does not perform the listen-before-talk LBT detection. Specifically, the sender device can directly access the unauthorized channel without performing LBT before accessing the unauthorized channel.

[0061] It is necessary to provide a solution for how the sender device determines the access method.

[0062] In the present disclosure, the sender device and the receiver device can be various devices such as user equipment, base stations, core network devices, and network-side devices.
