Abstract
A communications device for transmitting data to a wireless communications network is configured to transmit a random access preamble, and to transmit uplink data in an uplink shared physical channel associated with the preamble according to a 2-step random access procedure, the association between the preamble and the uplink shared channel being known to the wireless communications network. The communications device is configured to detect, in response to transmitting the preamble and the uplink data, a random access response message providing timing advance information and uplink grant of resources of the uplink shared channel according to a 4-step random access procedure. In response to detecting the random access response message, the communications device is configured to transmit uplink data in the uplink resources granted in the random access response message according to a 4-step random access procedure, as if the communications device was continuing with a 4-step RACH procedure having started with a 2-step RACH procedure. As such there is no requirement to fall-back to a full 4-step random access procedure, if a 2-step random access procedure has failed, thereby saving time and communications resources.
