Abstract

The present invention provides a random access method and related equipment. The method includes: performing pre-speak LBT operation on the LBT frequency band corresponding to RO resources at N physical random access channel opportunities, and selecting from the N RO resources M target RO resources; wherein, there are at least two RO resources corresponding to different LBT frequency bands among the N RO resources, and the target RO resources are RO resources with successful LBT among the N RO resources, and N is greater than 1 is an integer, M is an integer less than or equal to N and greater than or equal to 1; using the M target RO resources to send a preamble. Through the random access method provided by the present invention, the probability of Msg1 transmission delay in the random access process can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a random access method and related equipment. Background technique [0002] In a future communication system, an unlicensed frequency band (ie, Unlicensed Band) can be used as a supplement to a licensed frequency band (ie, Licensed Band) to help operators expand service capacity. Since the unlicensed frequency band is shared by multiple radio access technologies (Radio Access Technology, RAT for short), for example, WiFi, radar, and Long Term Evolution-License Assisted Access (LTE-LAA for short) etc. Therefore, the unlicensed frequency band must comply with the specifications to ensure that all devices can use the resource fairly, for example, listening before speaking (ListenBefore Talk, referred to as LBT), maximum channel occupancy time (Maximum Channel Occupancy Time, referred to as MCOT) and other rules. Among them, the above-mentioned LBT refers to that the...
