Embodiment approach 1

[0122] When M is less than or equal to 2048, the LAA station copies the content of M sampling points from the 2048-M+1 to the 2048th of the next symbol of the current symbol of the unlicensed carrier, and obtains content from the competition on the unlicensed carrier When the unlicensed carrier arrives, the contents of the copied total M sampling points are sent;

[0123] When M is greater than 2048 but less than or equal to 2192, the LAA station copies the content of the first to M sampling points of the next symbol of the current symbol of the unlicensed carrier, and from contention to M on the unlicensed carrier The time when the unlicensed carrier starts to send the content of the copied M sampling points;

[0124] When M is greater than 2192, the LAA station copies the content of the 1st to 2192th sampling points of the next symbol of the unlicensed carrier, and repeats from the moment when it competes for the unlicensed carrier on the unlicensed carrier Send the copied ...

Embodiment approach 2

[0126] When M is less than or equal to 2048, the LAA station starts to send the CRS or other occupancy signals of the first M sampling points among the 2048 sampling points on the unlicensed carrier from the moment when it competes for the unlicensed carrier;

[0127] When M is greater than 2048 but less than or equal to 2192, the LAA station starts sending the CRS or other occupancy signals of the first M sampling points of the 2192 sampling points on the unlicensed carrier from the moment when the unlicensed carrier is occupied , wherein the content of the first 144 sampling points in the CRS of the 2192 sampling points or other occupied signals is a copy of the last 144 sampling points;

[0128] When M is greater than 2192, the LAA station repeatedly sends the CRS or other occupied signals for 2192 sampling points on the unlicensed carrier from the moment it occupies the unlicensed carrier until the current subframe and the next subframe of the authorized carrier The subfra...

Embodiment approach 3

[0130] When M is less than or equal to 2048, the LAA station starts to send 2048+K sampling points of the cell-specific reference signal CRS or other occupied signals on the unlicensed carrier from the moment when it competes for the channel, where K is no more than a non-negative integer of 160; or,

[0131] When M is less than or equal to 2048 and when the LAA station sends 2048+K sample points of cell-specific reference signal CRS or other occupied signals on the unlicensed carrier, the next subframe of the current subframe of the unlicensed carrier The first 2048+K-M sampling points of the subframe will be punctured.

[0132] In addition, in the optional implementation manner of this embodiment, it also involves the manner in which the LAA station sends the CRS, which can be implemented in the following manner: the LAA station sends the CRS on different resource elements RE of a physical resource block PRB The CRS, where the CRS is used on different REs to indicate differ...

Abstract

The present invention provides a channel occupation method and device. The method comprises the steps that a license assisted access (LAA) site sends an occupation signal and / or channel to a first LAA site and / or first LAA user equipment near the LAA site through an unlicensed carrier and / or licensed carrier, the first LAA site and / or first LAA user equipment (UE) receives the occupation signal and / or channel, wherein the occupation signal and / or channel are used for indicating the LAA site to compete to obtain the unlicensed carrier and occupy the occupation information of the unlicensed carrier. Through the invention, the problems of taking-away of the unlicensed carrier, occupation time length and a 'hidden site' in the related technology are solved, and the efficiency of channel occupation is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a channel occupation method and device. Background technique [0002] Unlicensed carrier (ie, license-free spectrum) refers to the spectrum (or carrier) that can be used directly without authorization under the relevant regulations (radio regulation) of government departments (such as the National Radio Regulatory Commission). In our daily life, unlicensed carriers are used in microwave ovens, remote-controlled toy airplanes, wireless mice, wireless keyboards, high-fidelity wireless Internet access (Wireless Fidelity referred to as WiFi), and authorized carrier-assisted access LTE (hereinafter referred to as LAA). [0003] Before using a certain unlicensed carrier, a station (or device) should first measure or sense the channel (that is, the "channel" here refers to the unlicensed carrier). The process of sensing the channel is called Clear Channel Assessment (Clear Channel As...
