Method and apparatus for acknowledging a reception of a data packet in a CDMA communication system
First Claim
1. A method for acknowledging reception of a packet of data in a communication system, comprising:
- receiving, at a serving base, a message on an acknowledgement channel for indicating said reception of said packet of data at a mobile station;
determining an erasure of said message at said serving base station;
receiving said message at a non-serving base station on said acknowledgement channel from said mobile station;
determining a value of said message at said non-serving base station;
communicating said value of said message from said non-serving base station to said serving base station; and
changing, at said serving base station, said erasure to said value of said message.

Abstract
In a communication system (100), a method and an accompanying apparatus provide for acknowledging reception of a packet of data. A receiver (400) at a serving base station (101) receives a message on an acknowledgement channel (340) for indicating the reception of the packet of data at a mobile station (102), and may determine an erasure of the message. A non-serving base station (160) may also receive the message on the acknowledgement channel (340) from the mobile station (102), determines a value of the message, and communicates the value of the message to the serving base station (101). The serving base station (101) changes the erasure to the value of the message, and terminates a transmission of a remainder of data units of the packet of data to the mobile station (102) when the value of the message is a positive acknowledgment from the non-serving base station (160).

11. In a communication system, an apparatus for acknowledging reception of a packet of data, comprising:
-
a serving base station receiver, in a serving base station, for decoding a message on an acknowledgement channel for indicating said reception of said packet of data at a mobile station and determining an erasure of said message at said serving base station;
a non-serving base station receiver, in a non-serving base station, for decoding said message on said acknowledgement channel from said mobile station and determining a value of said message at said non-serving base station;
a communication system back-haul for communicating said value of said message from said non-serving base station to said serving base station; and
a serving base station controller, in said serving base station, for changing said erasure to said value of said message. - View Dependent Claims (12, 13, 14, 15, 16, 17)
