First Claim
1. A method for acknowledging reception of a packet of data, comprising:
- receiving, at a serving base station, a message on an acknowledgement channel determined as one of a positive or negative acknowledgement for indicating said reception at a mobile station of said packet of data transmitted by said serving base station;
determining an erasure of said message at said serving base station;
receiving a value of said message from a non-serving base station at the serving base station; and
changing, at said serving base station, said erasure based on said value of said message received from the non-serving base station wherein said value of said message from non-serving base station indicating positive or negative acknowledgment.

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).
