Abstract

The invention discloses an information transmission method, a base station and a terminal. The method applied to the base station comprises the following steps of receiving a retransmission request message which is sent by the terminal; determining an available unlicensed spectrum used for carrying out downlink data transmission within a first appointed time; selecting at least one unoccupied available unlicensed spectrum as a first frequency spectrum used for sending retransmission data within a second appointed time from the available unlicensed spectrum, wherein the second appointed time is a time subset within the first appointed time; utilizing the first frequency spectrum to send the retransmission data within the second appointed time, wherein a frequency spectrum for transmitting initial transmission data corresponding to the retransmission data is a second frequency spectrum; and the first frequency spectrum and the second frequency spectrum are the same or different.

Description

technical field [0001] The present invention relates to retransmission technology in the communication field, and in particular to an information transmission method, a base station and a terminal. Background technique [0002] The LAA (Licensed-Assisted Access to Unlicensed Spectrum) system can not only use the authorized frequency band for information transmission, but also can use the unlicensed frequency band for information transmission. For example, it can reuse the frequency band of WiFi in the fifth generation 5G (multiplexed WiFi in 5G The frequency band is the above-mentioned unlicensed frequency band), and the data throughput of the communication network is improved through carrier aggregation. Those available unlicensed frequency bands all belong to secondary cells (secondary cells, Scells) in the carrier aggregation technology. Each Scell ​​is a CC (carrier component). [0003] In the prior art, if the base station uses the frequency band A to send new data to...
