A method, device and system for indicating spectrum resources

Abstract

Embodiments of the present invention provide a spectrum resource indication method, device, and system, which relate to the field of communication technologies and can improve data transmission efficiency. The method includes: the access network device acquires the capability of the terminal device to support spectrum resources and the service requirements of the terminal device, and the access network device determines spectrum resource information for the terminal device according to the capability of the terminal device to support spectrum resources and the service requirements of the terminal device , and the access network device sends a spectrum resource indication message to the terminal device, where the spectrum resource indication message is used to indicate the spectrum resource information.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for indicating frequency spectrum resources. Background technique [0002] With the continuous development of communication technology, the Internet of Things has developed rapidly. Since the number of terminal equipment connected to the Internet of Things is increasing, and the business requirements of different terminal equipment connected to the Internet of Things are very different, it is bound to bring pressure on the use of spectrum resources, so it is reasonable in the Internet of Things The utilization of spectrum resources has become an urgent problem to be solved. [0003] Current spectrum resources include licensed spectrum resources and unlicensed spectrum resources. Usually, in the application of unlicensed spectrum resources, all terminal devices within the coverage of the same access network device only use the listen before talk (LBT...

Problems solved by technology

[0004] However, in the application of the above-mentioned unlicensed spectrum resources, since all terminal devices within the coverage of the same access network device only use the LBT method or the low duty cycle method to compete for the frequency band on the unlicensed spectrum resources, it may cause Multiple terminal devices compete for the same frequency band on unlicensed spectrum resources at the same time, so the multiple terminal devices may send data on this frequency band at the same time, resulting in the failure of some terminal devices to send data, reducing the data transmission efficiency
