Embodiment Construction

[0070] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0071] Before introducing and describing the embodiments of the present disclosure, the channel detection mechanism involved in the present disclosure is explained first.

[0072] Channel detection mechanisms can generally include the following five types:

[0073] The first type (Cat.1): does not contain LBT (Listen before talk, listen before talk), that is, the device does not need ...

Abstract

The invention discloses a channel detection method and apparatus on an unlicensed spectrum, and a storage medium. The method comprises the steps: for a target beam of n beams, determining a channel detection mechanism corresponding to the target beam, wherein n is an integer greater than one; and according to the channel detection mechanism corresponding to the target beam, detecting whether the channel corresponding to the target beam is idle. An embodiment of the present disclosure provides a channel-based channel detection scheme for an unlicensed spectrum scenario. The channel detection mechanisms are independently determined for channels corresponding to different beams, and channel detection is performed on channels corresponding to the respective beams. Channel detection results aremore accurate and more beneficial for beam-based transmission and reception.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of communications, and in particular to a channel detection method, device and storage medium on an unlicensed frequency spectrum. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) communication system, when using unlicensed spectrum, the signal is transmitted omnidirectionally through the omnidirectional antenna, therefore, the channel detection before channel access is also based on the omnidirectional antenna channel detection . For example, the base station needs to detect the RSSI (Received Signal Strength Indicator) around the base station before sending information on the unlicensed spectrum. Since the above RSSI is received based on omnidirectional antennas, the above RSSI is a certain time granularity The sum of the RSSIs that can be received in all directions; then compare the sum of the RSSIs that can be received in all directions with ...
