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.

35. A method of communicating with a subscriber station comprising:
-
a. allocating a first set of transmission resources to be used as a first uplink control transmission resource, the first uplink control transmission resource being shared by the subscriber station with a plurality of remote subscriber stations; b. allocating a second set of transmission resources to be used as a second uplink control transmission resource, the second uplink control transmission resource being an uplink control channel to be used by the subscriber station; c. communicating to the subscriber station the allocations of the first set of transmission resources and the second set of transmission resources; d. listening for transmission by the subscriber station of uplink control signals on at least one of the first and second set of transmission resources. - View Dependent Claims (36, 37, 38, 39, 40)
