US 2022/0279591 A1 · RANDOM ACCESS METHOD AND APPARATUS

Abstract

This application provides a random access method and apparatus. The method includes: A terminal device receives first information sent by a network device, where the first information includes a priority value of a first parameter used for a random access procedure. The terminal device initiates the random access procedure based on the priority value. In this way, the terminal device can preferentially select, based on the priority value of the first parameter, a two-step random access procedure or send a message in the random access procedure by using high power, to quickly access a network and reduce an access delay.

Claims12

Dependent claims

A communication method, implemented by a terminal device, comprising:

determining that a counter reaches a maximum value of a listen before talk (LBT) failure count;
switching an active bandwidth from a first bandwidth part to a second bandwidth part;
initiating a random access process on the second bandwidth, wherein the counter is configured to record a quantity of LBT failures;
and
stopping an ongoing random access procedure on the first bandwidth part.
