1. A method comprising:
receiving a system information block (SIB1) including configuration information;
identifying, based on the configuration information, a random access channel (RACH) configuration;
identifying, based on the configuration information, whether an early access indication associated with a full-duplex operation is enabled;
determining to use a first random access transmission configuration when the early access indication is enabled or a second random access transmission configuration when the early access indication is not enabled; and
transmitting a random access message using the determined first or second random access transmission configuration.
