A user equipment, for use in a wireless communication system, comprises a receiver to receive resource usage information transmitted from a base station over an acquisition (or acknowledgement) indicator channel, and a controller operatively coupled to the receiver, to determine an available resource, with a high probability of success, based on the received resource usage information. A transmitter operatively coupled to the controller, is provided to transmit an access attempt signal and data packets over a random access channel, with the access attempt signal adapted to the available resource to request the base station to permit the user equipment access to the random access channel.
