1. A method of processing a Random-Access Response (RAR) message received by a User Equipment (UE) from a network entity, wherein the method comprises performing the following by the UE:
receiving one or more RAR messages from the network entity, wherein each RAR message includes a RAR message-specific time-delay indicator in a respective Uplink (UL) grant for the UE carried by the RAR message, wherein each RAR message-specific time-delay indicator specifies a UL time interval in which the UE is scheduled to transmit in the UL to the network entity;
detecting at least one of the one or more RAR messages; and
sending a response to the detected at least one of the one or more RAR messages during the UL time interval specified by the detected at least one RAR message.
