A method of wireless communication comprising: receiving, by a first wireless communication device from a second wireless communication device, a plurality of transmit opportunities (406, 410, 412) in a shared channel; determining, by the first wireless communication device, whether the shared channel is in use prior to a transmit opportunity from among the plurality of transmit opportunities; and starting, by the first wireless communication device, a timer in response to: successfully transmitting a random access message during the transmit opportunity when the shared channel is determined to not be in use, or failing to successfully transmit the random access message during any of the plurality of transmit opportunities when the shared channel is determined to be in use; wherein the random access message is part of a two-step random access procedure; the method characterized by: receiving, by the first wireless communication device from the second wireless communication device, a random access response in the shared channel during a random access window; determining, by the first wireless communication device in response to the random access response not including an identifier of the first wireless communication device, whether the random access response includes an indication of a subsequent random access response pending from the second wireless communication device during the random access window; and monitoring, by the first wireless communication device, for the subsequent random access response from the second wireless communication device in the shared channel in response to determining that the random access response includes the indication during the random access window. receiving, by a first wireless communication device from a second wireless communication device, a plurality of transmit opportunities (406, 410, 412) in a shared channel;
