Abstract

The embodiment of the present invention discloses a transmission method, including: if a terminal in a long-term evolution network needs to use an unlicensed frequency band to transmit uplink data, notify the base station, and receive a resource allocation notification message returned by the base station, the resource allocation notification The message contains resource block information allocated by the base station for the terminal; calculates the average power of the corresponding frequency bandwidth according to the resource block information; judges whether the average power reaches a preset channel busy-idle state threshold; if the average If the power does not reach the preset channel busy-idle state threshold, the resource allocated by the base station is used for service transmission. The embodiment of the invention also discloses a terminal. By adopting the invention, the compatibility between the LTE network and the existing network using the unlicensed frequency band can be realized.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a transmission method and a terminal. Background technique [0002] With the rapid increase of communication traffic, the licensed spectrum of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) appears to be less and less sufficient to provide higher network capacity. In order to further improve the utilization of spectrum resources, 3GPP is discussing how to use unlicensed spectrum, such as 2.4GHz and 5GHz frequency bands, with the help of licensed spectrum. These unlicensed spectrums are currently mainly used by systems such as Wireless-Fidelity (Wi-Fi for short), Bluetooth, radar and medical treatment. Compared with Wi-Fi and other networks, the Long Term Evolution (LTE) network operating in the unlicensed frequency band has the ability to provide higher spectral efficiency and greater coverage effect, and at the same ...
