Abstract

The invention discloses a resource allocation indication method of an LTE (Long Term Evolution) system on an unauthorized frequency band, a resource allocation indication method of the LTE system on the unauthorized frequency band, a base station and a terminal. The indication method applied in the base station comprises following steps: determining the working bandwidth of the LTE system on the unauthorized frequency band; adjusting the size of a resource block group and/or the alternative value of the resource block group corresponding to the working bandwidth; determining the size of a target resource block group according to the adjusted size of the resource block group and/or the alternative value of the resource block group; informing the terminal of the size of the target resource block group and the allocation information of the resource block group through a target signaling, thus allocating one or multiple resource block groups to the terminal. Through the technical solution of the invention, the bit quantity occupied by the resource allocation domain in the DCI signaling can be effectively reduced on the unauthorized frequency band; and the signaling cost can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a method for indicating resource allocation when an LTE system works in an unlicensed frequency band, a device for indicating resource allocation when an LTE system works in an unlicensed frequency band, a terminal and A base station. Background technique [0002] With the rapid increase of communication traffic, 3GPP (The3 rd GenerationPartnershipProject, the third generation mobile communication partnership organization) The licensed frequency band is increasingly insufficient to provide higher network capacity. In order to further improve the utilization of frequency band resources, 3GPP is discussing how to use unlicensed frequency bands, such as 2.4GHz and 5GHz frequency bands, with the help of licensed frequency bands. These unlicensed frequency bands are currently mainly used by Wi-Fi, Bluetooth, radar, medical and other systems. [0003] Usually, access...
