First Claim
Patent Images
1. A method of operating a timer for processing data blocks by a terminal in a communications system, the method comprising:
- storing, by the terminal, a data block with a sequence number in a buffer;
starting, by the terminal, a timer when the data block with the sequence number is stored in the buffer; and
if the timer expires, starting, by the terminal, the timer based on a highest sequence number of a data block among first data blocks that cannot be delivered to a higher entity.

Abstract
A timer for processing data blocks is proposed for a receiver of a mobile communications system. If the timer is not running, the timer is started based a data block. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. If the timer is stopped or expires, the timer is based on a highest sequence number of a data block among data blocks that cannot be delivered to a higher entity. The timer can be used to prevent a stall condition in mobile communications.

10. A terminal in a communications system, the terminal comprising:
-
a buffer configured to store a data block with a sequence number; and a timer configured to, start the timer when the data block with the sequence number is stored in the buffer, and if the timer expires, start the timer based on a highest sequence number of a data block among first data blocks that cannot be delivered to a higher entity. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
