Embodiment Construction

[0036] The executor of the first embodiment of the scheduling method using unlicensed spectrum of the present invention is a base station. The base station is connected to the core network and performs wireless communication with user equipment, providing communication coverage for the corresponding geographic area. The base station may be a macro base station, a micro (micro) base station, a pico base station, or a femtocell (femtocell). In some embodiments, a base station may also be called a wireless base station, an access point, a Node B, an evolved Node B (eNodeB, eNB), a gNB, or other suitable terms. Such as figure 1 As shown, this embodiment includes:

[0037] S11: Obtain the channel busy rate of the unlicensed spectrum.

[0038] The channel busy rate is used to indicate the statistical probability of channel occupation failure. For a certain channel, the higher the channel busy rate, the busier the channel, the more users sharing the channel, and the higher the probabil...

Abstract

The invention discloses a scheduling method using an unlicensed frequency spectrum. The method includes: obtaining the channel busy rate of the unlicensed spectrum; selecting and scheduling user equipment according to the channel busy rate, and the number of scheduled user equipment is greater than or equal to the number of receiving antennas of a base station; The scheduling grant instruction is sent to the scheduling user equipment so that the scheduling user equipment tries to use the channel in the unlicensed spectrum for uplink transmission according to the scheduling grant instruction. The invention also discloses a communication method and device using unlicensed spectrum and a scheduling device using unlicensed spectrum. Through the above method, the present invention can improve channel multiplexing gain and system throughput.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for scheduling and communications using unlicensed spectrum. Background technique [0002] With the rapid development of wireless communication and the continuous increase of communication demands, the scarcity of spectrum resources, especially authorized spectrum resources, has become an important challenge for mobile communication. In order to meet the continuously increasing demands of user equipment for speed, traffic, and bandwidth and solve the current crisis of spectrum scarcity, 3GPP has begun to study Licensed Assisted Access (LAA). LAA is an auxiliary access technology that offloads cellular communication traffic to unlicensed spectrum. [0003] LAA technology may cause interference to other wireless communication technologies currently working in this frequency band, such as Wi-Fi, and LAA networks deployed by different operators may also interfe...
