US 2019/0174550 A1 · RANDOM ACCESS METHOD, TERMINAL, AND NETWORK DEVICE

Abstract

This application provides a random access method, a terminal, and a network device. The random access method includes: determining, by a terminal, whether a resource used for random access conflicts with a resource used for receiving a downlink signal; and if the resource used for the random access conflicts with the resource used for the downlink signal, preferentially using the conflicting random access resource for receiving the downlink signal but not for the random access. This avoids a conflict between receiving of the downlink signal and sending of an uplink random access preamble.

Dependent claims

A random access method, comprising:

receiving information about random access resources from a network device;
determining whether there is a random access resource that overlaps with a time resource for receiving a synchronization signal block;
and
if there is a random access resource overlaps with a time resource for receiving a synchronization signal block, sending a random access preamble to the network device based on the random access resources excluding the overlapping random access resource.

1 more element

An apparatus, comprising:

one or more memories configured to store instructions;
and
one or more processors coupled to the one or more memories and configured to execute the instructions, cause the apparatus to:
receive information about random access resources from a network device;
determine whether there is a random access resource that overlaps with a time resource for receiving a synchronization signal block;
and
if there is a random access resource overlaps with a time resource for receiving a synchronization signal block, send a random access preamble to the network device based on the random access resources excluding the overlapping random access resource.
