Patent ID: 7668192

Claim:
Method for execution in a base station, comprising: receiving by a receiver in the base station over a radio interface from a user equipment a retransmission sequence number signal having a magnitude indicative of a number of retransmissions of data from the user equipment to the base station that resulted in a correct decoding of said data, wherein values of said number are limited to a first range, determining by a determiner in the base station if the base station has received a retransmission sequence number but has not been able to determine or has not been able to accurately determine the number of retransmissions of said data from the user equipment that resulted in said correct decoding of said data, and selecting signalling by a selector in the base station for transmission on a frame protocol data frame header to a serving radio network controller to indicate that the base station does not have information about an actual number of said retransmissions of data from the user equipment to the base station.
