1. An access unit comprising:

  • circuitry configured to transmit on a first channel, a second channel and a third channel;

    wherein the first channel is an access channel and the second channel carries traffic data;

    wherein the third channel is transmitted on a condition that the access unit is not allocated resources for the second channel; and

    wherein the circuitry is further configured to transmit an indication on the third channel that the access unit is requesting to be allocated the second channel to transmit traffic data;

    wherein the transmitted indication is produced by a data value of one for a duration of at least one time slot and orthogonal sequences.
