Abstract

Provided are an information sending method, a random access method, a terminal device and a network side device. The random access method comprises: simultaneously performing clear channel assessment(CCA) on M first-listen then-talk (LBT) channels, where M is greater than 1; and sending the lead code information Msg1 on one idle LBT channel in the M LBT channels. Because CCA is carried out on theM LBT channels at the same time, the opportunity of grabbing idle LBT channels on an unauthorized frequency band is increased, the waiting time of the UE is reduced, and the random access time is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a random access method. Background technique [0002] In the future communication system, the unlicensed frequency band (Unlicensed Band) can be used as a supplement to the licensed frequency band (Licensed Band) to help operators expand the service capacity. In order to be consistent with New Radio (NR) deployment and maximize NR-based unlicensed access as much as possible, the unlicensed frequency band can work in the 5GHz, 37GHz and 60GHz frequency bands. Since the unlicensed frequency band is shared by multiple technologies (RATs), such as WiFi, radar, LTE-LAA, etc., in some countries or regions, the unlicensed frequency band must comply with the regulations to ensure that all devices can use the resource fairly , such as LBT (Listen Before Talk), the duration of a single transmission shall not be longer than the preset maximum channel occupancy time MCOT (Max...
