Abstract

The invention discloses an information transmission method of an unlicensed frequency band, a terminal and a network device. The method includes: within a message-time window corresponding to a message, intercepting transmission resources of an unlicensed frequency band to determine a target transmission channel ; Send message 1 to the network device at the physical random access channel transmission opportunity RO in the target transmission channel, where the time window of message 1 corresponds to message 1 of the random access procedure. The terminal in the embodiment of the present invention listens to the transmission resources of the unlicensed frequency band within the message 1 time window, and sends the message 1 on the RO in the idle target transmission channel, so as to intercept the unlicensed frequency band in a targeted manner, The success rate of detecting an idle channel can be improved, thereby improving the success rate of a random access process.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an information transmission method, a terminal and a network device in an unlicensed frequency band. Background technique [0002] In a mobile communication system, an unlicensed frequency band (unlicensed band) can be used as a supplement to a licensed frequency band (licensed band) to help operators expand service capacity. Since the unlicensed frequency band is shared by a variety of radio access technologies (Radio Access Technology, RATs), such as WiFi, radar, Long Term Evolution License Assisted Access (LTE-LAA), etc., the unlicensed frequency band is in use must comply with certain regulations (regulation) to ensure that all devices can use the resource fairly, such as listening before talking (ListenBefore Talk, LBT), maximum channel occupancy time (Maximum Channel Occupancy Time, MCOT), occupied bandwidth (occupied channel bandwidth, OCB) and other rules.
