Auxiliary ACK channel feedback for control channels and broadcast multicast signals

A method for providing an assignment acknowledgement, the method comprising:

• decoding forward link control channel data blocks according to parameters provided by an overhead channel message;
• receiving forward link packet data at an access terminal (AT) via a data channel;
• identifying an offset which defines that a certain number of subpackets of the packet data have been transmitted before the assignment acknowledgement is to be transmitted;
• and
• transmitting the assignment acknowledgement according to the offset to indicate successful decoding of one of the control channel data blocks only if the packet data has not been acknowledged.

A method for providing an assignment acknowledgement, the method comprising:

• receiving a forward link overhead channel message at an access terminal (AT), the overhead channel message comprising a parameter used to indicate which shared control channel (SCCH) data blocks are to be acknowledged by the AT;
• receiving a forward link SCCH signal comprising SCCH data blocks;
• decoding the SCCH data blocks according to parameters provided by the overhead channel message;
• detecting a change in access terminal assignment for the AT based upon the SCCH signal;
• transmitting reverse link packet data from the AT via a data channel;
• identifying an offset which defines that a certain number of subpackets of the packet data have been transmitted before the assignment acknowledgement is to be transmitted according to parameters provided by the overhead channel message;
• and
• transmitting the assignment acknowledgement according to the offset to indicate successful decoding of one of the SCCH data blocks only if the packet data has not been acknowledged and if the overhead channel message indicates that the block is to be acknowledged.
