Embodiment Construction

[0061] The present invention provides a method and device for channel occupation of unlicensed spectrum, which is mainly used for unlicensed spectrum, and can provide more fine-grained channel occupancy parameters for terminal equipment, so that terminal equipment can know the overall picture of channel occupancy configuration during channel occupancy, Therefore, it is beneficial for the terminal equipment to reduce the monitoring of the downlink channel, and correspondingly reduce the power consumption of the terminal equipment.

[0062] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on The embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creati...

Abstract

The invention provides an unauthorized spectrum channel occupation method and device. The method comprises the following steps: a network side device generates first control information, wherein the first control information is used for indicating a channel occupation parameter in at least one COT; the network side device sends the first control information to at least one terminal device, so thatthe at least one terminal device communicates with the network side device in the at least one COT according to the first control information. By adoption of the scheme, on the premise of reducing the signaling cost of the channel occupation parameter of dynamic notification, the terminal device can know the channel occupation configuration full view during the channel occupation and then flexibly adjust the monitoring of a downlink channel according to the channel occupation parameter with better granularity provided by the first control information, thereby being beneficial for the terminaldevice to monitor the downlink channel and correspondingly reducing the power consumption of the terminal device.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and equipment for occupying an unlicensed spectrum channel. Background technique [0002] In a communication system based on unlicensed spectrum deployment, each node judges its busy status by the received power on the unlicensed spectrum. If the received power is less than a certain threshold, it is considered that there is no interference source on the unlicensed spectrum and it is in an idle state. , then you can send signals on the unlicensed spectrum. This mechanism of listening first and then sending is called listening before talking (English full name: Listen Before Talk, English abbreviation: LBT), which can avoid the use of non-licensed Conflicts when authorizing spectrum resources. Since each node uses / shares wireless resources through competition, the starting time of transmission on the unlicensed spectrum is not fixed, and the frequency doma...
