Acknowledging broadcast transmissions
First Claim
Patent Images
1. An apparatus in a base station for evaluating an acknowledgment transmission from a remote station, comprising:
- a memory element; and
a processing element configured to execute a set of instructions stored on the memory element, the set of instructions for;
decoding an acknowledgment message sent on a dedicated packet channel;
determining the identity of a Walsh code sequence covering the acknowledgment message;
using the acknowledgment message to determine whether a dedicated transmission was decoded by the remote station; and
using the identity of the Walsh code sequence to determine whether a broadcast transmission was decoded by the remote station.

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.
