Embodiment Construction

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of this application.

[0042] Beam-based channel detection means that the device uses a receiver based on the beam direction to detect the energy on the channel where the spectrum is located. If it detects that the channel where the spectrum is located in the beam direction is available, it means that it can be in the channel where the spectrum is located. Send in the beam direction. That is, the beam receiving direction corresponds to the beam sending direction, and it is detect...

Abstract

The embodiment of the application discloses a beam-based channel detection method and equipment, which are used to improve the beam-based channel detection efficiency and improve the use efficiency ofunlicensed spectra. The method disclosed by the embodiment of the application includes the following steps: when the equipment needs to occupy a channel where a spectrum is located to perform data transmission, the equipment determines a main beam and performs a complete channel detection process on the main beam, and when determining that the channel where the the spectrum is located in the direction of the main beam can be occupied, the equipment adopts a simplified channel detection process with fewer detection steps relative to the complete channel detection process for channel detectionin the directions of other beams. Thereby, the overall channel detection steps can be reduced, and the channel detection efficiency can be improved.

Description

Technical field [0001] This application relates to the field of communications, and in particular to a beam-based channel detection method and device. Background technique [0002] As the mobile Internet enters a new growth stage, and more mobile terminals are connected to each other and share more abundant data, operators are facing the challenge of a thousand-fold increase in mobile data traffic. To this end, a set of combined methods is needed from different perspectives, including the use of more spectrum, more effective use of existing spectrum, and deployment of more small base stations to increase the capacity of the mobile communication system. From the earliest analog cellular communications to the second-generation GSM / IS-95, the third-generation WCDMA / CDMA2000 / TD-SCDMA and the latest LTE 4G technology, the spectrum efficiency has been greatly improved. For example, the LTE FDD network has a 20MHz bandwidth, In the case of 2X2MIMO, the downlink rate has reached 150Mbps...
