UPLINK CONTROL SIGNAL DESIGN FOR WIRELESS SYSTEM
First Claim
1. A method for execution by a subscriber station for transmitting an uplink control message to a base station, the method comprising:
- a. determining a size of the uplink control message;
b. selecting an encoding scheme on the basis of the size of the uplink control message;
c. encoding the uplink control message according to the selected encoding scheme to obtain an encoded uplink control message;
d. modulating the encoded uplink control message according to a modulation scheme to obtain a modulated uplink control message;
e. transmitting the modulated uplink control message uplink to the base station over a wireless interface;
wherein selecting an encoding scheme comprises selecting a first encoding scheme being a code division multiplexing scheme if the size of the uplink control message is within a first size range, and selecting a second encoding scheme being a block code scheme if the size of the control message is within a second size range above the first size range.

Abstract
Transmission of uplink control message for a wireless system. The uplink control message may be encoded according to one of multiple possible schemes. The choice of encoding scheme may be made based on the control message size and/or based on the available transmission resources and/or based on the detection scheme used on the receiving end. A modulation scheme may also be selected based on such factors. CDM may be used for certain control messages. Block code encoding, such as Reed-Muller encoding may be used for certain control messages. Different transmission resources may be allocated for different control message uses. The encoding specifics may be selected to obtain a certain hamming distance and/or size of the encoded message or based on other factors.
