ABSTRACT:
Methods and apparatus are presented for acknowledging broadcast transmissions. An acknowledgment channel is designed for acknowledging the success or failure of a transmission on a dedicated channel and on a broadcast channel. Acknowledgments are generated based on whether a new orthogonal space is sent to a remote station or not. Moreover, an acknowledgment to the broadcast transmission is generated when an acknowledgment is needed for a dedicated transmission. The two acknowledgments are combined and sent to a base station.
