Embodiment Construction

[0113] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0114] Such as figure 1 As shown, the subframe structure in the embodiment of the present invention, in chronological order, specifically includes:

[0115] It includes the part that allows the execution of clear channel detection CCA_1 or eCCA_1 (the following "1" is to distinguish different CCA or eCAA (Enhanced Clear Channel Assessment)).

[0116] Wherein, the base station executes CCA or eCCA within this time period. The actual duration of CCA_1 or eCCA_1 is fixed or may vary. The duration of CCA_1 or eCCA_1 can be less than 9us / 34us / 40us. At this time, the base sta...

Abstract

The embodiment of the invention discloses an unauthorized carrier based data transmission method and device. The unauthorized carrier based data transmission method comprises the steps that a site performs idle channel detection on an unauthorized carrier according a subframe structure of the unauthorized carrier, the right to use the unauthorized carrier is acquired according to a result of idle channel detection, and data transmission is performed by using the unauthorized carrier with the right to use. The embodiment of the invention further discloses a resource seizing method and device.

Description

technical field [0001] The present invention relates to an unlicensed carrier application technology, in particular to a data transmission method and device based on an unlicensed carrier, and a resource preemption method and device. Background technique [0002] The Long Term Evolution (LTE, Long Term Evolution) system is deployed on licensed carriers. With the evolution of LTE and the rapid growth of data services, the licensed spectrum will no longer be able to bear such a huge amount of data in the near future. Therefore, Deploying LTE in unlicensed spectrum can be considered to share the data traffic in licensed carriers through unlicensed spectrum. For the unlicensed spectrum, the communication cost is lower, and the requirements for access conditions are also low. Therefore, using the unlicensed spectrum may be an important evolution direction of the wireless communication system. [0003] There are also problems with using unlicensed spectrum for communication. For...
