Problems solved by technology

[0005] However, in practical applications, if an omnidirectional receiving antenna is used to detect the unlicensed spectrum based on beam transmission in NR, since the coverage angle of each beam is different, the channel energy it has when transmitting the signal is also different, so it cannot be accurately judged. Whether the channel in the beam direction is idle, reducing spectral efficiency and throughput

Abstract

The embodiment of the invention discloses an idle channel determination method and idle channel determination equipment based on beams. The method comprises the steps of detecting channel energy in afirst beam direction via a beam-based receiving antenna, wherein thresholds of channel detection energy in the beam directions with different coverage angles are different, and the threshold of the channel detection energy in the first beam direction is in reverse proportion to the coverage angle of the first beam, then comparing an acquired first energy value with the threshold of the channel detection energy in the first beam direction, and if the first energy value is less than the threshold of the channel detection energy in the first beam direction, accurately determining that a first alternative frequency band in the first beam direction is idle. According to the method, the different corresponding channel detection energy thresholds are used for the different beams, so that the accuracy of channel direction in each beam direction is greatly improved, and thus spectrum efficiency of the unauthorized spectrum in each beam direction is improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a beam-based method and device for determining channel idleness. Background technique [0002] As the mobile Internet enters a new growth stage, more mobile terminals are connected to each other and share more abundant data, and operators are faced with the challenge of a thousand-fold increase in mobile data traffic. To this end, a combined approach is needed to increase the capacity of the mobile communication system from different perspectives, including using more spectrum, using existing spectrum more effectively, and deploying more small base stations. From the earliest analog cellular communication, to the second generation GSM / IS-95, the third generation WCDMA / CDMA2000 / TD-SCDMA and the latest LTE 4G technology, the spectral efficiency has been greatly improved. For example, the LTE FDD network has a bandwidth of 20MHz, In the case of 2X2 MIMO, the downlink rate re...
