System and method for selecting a transmission channel in a wireless communication system that includes an adaptive array
A method for establishing wireless communication between a transmitter and a receiver in a wireless communication system is disclosed. The receiver includes an adaptive array that has at least two antennas. Each antenna receives a signal and produces a received signal. The transmitter includes at least two transmission channels for communicating the signal from the transmitter to the receiver. The wireless communication system suppresses interference at the receiver by applying an interference suppression technique when combining the received signals. The selection of a channel at the transmitter is based on the channel performance at the receiver for each transmission channel. The channel performance is based on a combining technique different from the interference suppression technique.
1. A method comprising:
receiving a first signal, where the first signal indicates reception of data;
transmitting a second signal in response to the first signal, where the second signal provides a list of acceptable transmission channels;
receiving the data via a third signal on an assigned channel while receiving a corresponding pilot frequency signal;
scanning a first signal frequency band to detect usage signals, where the usage signals correspond to occupied transmission channels; and
creating the list of acceptable transmission channels by removing the occupied transmission channels from a list of possible transmission channels.
2. The method of claim 1 , wherein the scanning the first signal frequency band proceeds according to a channel priority order.
3. The method of claim 1 , wherein the first signal is a paging signal.
4. The method of claim 1 wherein the assigned channel further comprises a plurality of channels.
5. The method of claim 1 , wherein the second signal comprises a time-division and a frequency-division.
6. The method of claim 1 , wherein the pilot frequency signal and the third signal do not form a continuous frequency band.
7. A system comprising:
a processor; and
a computer-readable storage device having instructions stored which, when executed by the processor, cause the processor to perform operations comprising:
receiving a first signal, where the first signal indicates reception of data;
transmitting a second signal in response to the first signal, where the second signal provides a list of acceptable transmission channels;
receiving the data via a third signal on an assigned channel while receiving a corresponding pilot frequency signal;
scanning a first signal frequency band to detect usage signals, where the usage signals correspond to occupied transmission channels; and
creating the list of acceptable transmission channels by removing the occupied transmission channels from a list of possible transmission channels.
8. The system of claim 7 , wherein the scanning the first signal frequency band proceeds according to a channel priority order.
9. The system of claim 7 , wherein the first signal is a paging signal.
10. The system of claim 7 wherein the assigned channel further comprises a plurality of channels.
11. The system of claim 7 , wherein the second signal comprises a time-division and a frequency-division.
12. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:
receiving a first signal, where the first signal indicates reception of data;
transmitting a second signal in response to the first signal, where the second signal provides a list of acceptable transmission channels;
receiving the data via a third signal on an assigned channel while receiving a corresponding pilot frequency signal;
scanning a first signal frequency band to detect usage signals, where the usage signals correspond to occupied transmission channels; and
creating the list of acceptable transmission channels by removing the occupied transmission channels from a list of possible transmission channels.
13. The computer-readable storage device of claim 12 , wherein the scanning the first signal frequency band proceeds according to a channel priority order.
14. The computer-readable storage device of claim 12 , wherein the first signal is a paging signal.
15. The computer-readable storage device of claim 12 the assigned channel further comprises a plurality of channels.
16. The computer-readable storage device of claim 12 , wherein the second signal comprises a time-division and a frequency-division.
