An access unit transmits a first channel, a second channel and a third channel. The first channel is an access channel and the second channel carries traffic data. The third channel is transmitted on a condition that the access unit has not allocated resources for the second channel. The access unit
An access unit transmits a first channel, a second channel and a third channel. The first channel is an access channel and the second channel carries traffic data. The third channel is transmitted on a condition that the access unit has not allocated resources for the second channel. The access unit produces an indication for transmission on the third channel. The transmitted indication is produced by a data value of one for a duration of at least one time slot and orthogonal sequences. The indication indicates that the access unit is requesting to be allocated the second channel to transmit traffic data.
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 all
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; andwherein 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. 2. The access unit of claim 1 wherein the orthogonal sequences are Walsh sequences. 3. The access unit of claim 1 wherein the access unit receives assignment information indicating time slots for which the access unit is permitted to transmit the indication. 4. The access unit of claim 3 wherein the assignment information indicates a repeating pattern of time slots that the access unit is permitted to transmit the indication. 5. The access unit of claim 1 wherein the transmitted indication is further produced by an additional sequence. 6. A method comprising: transmitting, by an access unit, 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; andproducing, by the access unit, an indication for transmission on the third channel; wherein the transmitted indication is produced by a data value of one for a duration of at least one time slot and orthogonal sequences; wherein the indication indicates that the access unit is requesting to be allocated the second channel to transmit traffic data. 7. The method of claim 6 wherein the orthogonal sequences are Walsh sequences. 8. The method of claim 6 further comprising receiving, by the access unit, assignment information indicating time slots for which the access unit is permitted to transmit the indication. 9. The method of claim 8 wherein the assignment information indicates a repeating pattern of time slots that the access unit is permitted to transmit the indication. 10. The method of claim 6 wherein the transmitted indication is further produced by an additional sequence. 11. A wireless network comprising: circuitry configured to receive, from an access unit, 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 received on a condition that the access unit is not allocated resources for the second channel; andwherein the circuitry is further configured to receive an indication on the third channel that the access unit is requesting to be allocated the second channel to transmit traffic data; wherein the received indication was produced by a data value of one for a duration of at least one time slot and orthogonal sequences; andwherein the circuitry is further configured to allocate the second channel to the access unit in response to receiving the indication. 12. The wireless network of claim 11 wherein the orthogonal sequences are Walsh sequences. 13. The wireless network of claim 11 wherein the circuitry is further configured to transmit assignment information indicating time slots for which the access unit is permitted to transmit the indication. 14. The wireless network of claim 13 wherein the assignment information indicates a repeating pattern of time slots that the access unit is permitted to transmit the indication. 15. The wireless network of claim 11 wherein the received indication was further produced by an additional sequence.
