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.
Claims12
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.
A method for evaluating an acknowledgment message from a remote station, comprising:
- decoding the 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.
An apparatus in a base station for evaluating an acknowledgment transmission from a remote station, comprising:
- means for decoding an acknowledgment message sent on a dedicated packet channel;
- means for determining the identity of a Walsh code sequence covering the acknowledgment message;
- means for using the acknowledgment message to determine whether a dedicated transmission was decoded by the remote station;
- and
- means for using the identity of the Walsh code sequence to determine whether a broadcast transmission was decoded by the remote station.
A computer-readable medium including executable program codes stored thereon, comprising:
- program code to decode an acknowledgment message sent on a dedicated packet channel;
- program code to determine the identity of a Walsh code sequence covering the acknowledgment message;
- program code to use a acknowledgment message to determine whether a dedicated transmission was decoded by the remote station;
- and
- program code to use the identity of the Walsh code sequence to determine whether a broadcast transmission was decoded by the remote station.
