1. A method of operating a user equipment (UE) in a communication network, the method comprising:
receiving a request comprising an indication for determining a set of channel access parameters from a base station node;
responsive to receiving the indication in a downlink control information (DCI) message, determining a first set of channel access parameters based on the request; and
responsive to receiving the indication in a random access response (RAR) message, determining a second set of channel access parameters based on the request, wherein the second set of channel access parameters is a subset of the first set of channel access parameters, wherein the indication indicates an entry point in a common table of channel access parameters, the entry point being different depending on whether the indication is received in the DCI message or in the RAR message.
