Abstract
A transmitter generates and transmits a low rate signal to its intended receiver. Upon receiving the low rate signal the intended receiver generates and transmits a channel sounding response (CSR) said CSR being a short burst having a predefined transmit format and carrying predetermined information. The transmitter then analyzes the CSR and determines uplink channel response estimates downlink channel response and determines appropriate transmit parameter settings based on the analysis and downlink response estimate. Adjustment of the transmit parameters can be made in either the MAC or PHY layer or in a combination of both. After adjusting its transmit parameters and modulating sub-carriers with user-data according to the determined transmit settings the transmitter transmits the user-data to the receiver on a preferred portion of bandwidth. In a preferred embodiment the transmitter also generates and transmits a transmit format control (TFC) signal containing the determined transmit parameter settings including sub-carrier modulation information to the receiver.

Claim
1. A wireless communications method for a wireless transmit/receive unit (WTRU), the method comprising:
receiving a channel sounding request (CSRq) from a base station, wherein the CSRq Includes channel sounding instructions;
transmitting a predefined channel sounding response (CSR) responsive to the CSRq, wherein the CSR is defined in terms of a number of symbols, size and symbol amplitude;
receiving from the base station an indicator of at least one transmit parameter setting for each of a plurality of subcarriers to be transmitted on by the base station, including modulation and coding parameters; and
receiving data that was transmitted by the base station using the at least one transmit parameter.
2. The method of claim 1 wherein the CSRq is a data packet header including source and destination information.
3. The method of claim 1 wherein the at least one transmit parameter setting is received in a transmit format (TF) signal.
4. The method of claim 3 wherein the TF signal includes power control parameters.
5. The method of claim 3 wherein the size of the CSR is the number of subcarriers.
6. The method of claim 1 wherein the at least one transmit parameter includes at least the plurality of sub-carriers on which the base station is transmitting the data.
7. The method of claim 4 wherein the TF signal includes modulation and coding schemes and power control.
8. The method claim of 1 further comprising:
transmitting data to the base station utilizing the received at least one transmit parameter setting.
9. A wireless transmit/receive unit (WTRU) comprising:
a receiver configured to transmit a channel sounding request (CSRq) including a channel sounding instructions from a base station;
at least one transmit/receive antenna configured to receive and transmit communication signals; and
a transmitter configured to transmit a predefined channel sounding response (CSR) in response to the channel sounding request, wherein the CSR is defined in terms of a number of symbols, size and symbol amplitude;
the receiver further configured to receive from the base station an indicator that indicates at least one transmit parameter setting for each of a plurality of subcarriers to be transmitted on by the base station
the receiver further configured to receive data that was transmitted by the base station using the at least one transmit parameter.
10. The WTRU of claim 9 wherein the at least one transmit parameter includes at least the plurality of sub-carriers on which the base station is transmitting the data.
11. The WTRU of claim 9 wherein the at least one transmit parameters setting is received in a transmit format (TF) signal.
12. The method of claim 11 wherein the TF signal includes power control parameters.
13. The WTRU of claim 11 wherein the TF signal includes modulation and coding schemes and power control.
14. The WTRU claim of 9 wherein the transmitter is further configured to transmit data to the base station utilizing the received at least one transmit parameter setting.
15. The WTRU of claim 9 wherein the size of the CSR is the number of subcarriers.
16. The WTRU of claim 9 wherein the CSRq is a data packet header including source and destination information.
