  • Method and apparatus for data management through timer compensation in a wireless communication system
    Patent number: 8756463
    Abstract: A method and an apparatus for data management through timer compensation in a wireless communication system are provided. In the method, when a data loss occurs at a first point, whether a data loss has occurred previously and so whether a timer is being driven are determined. Whether the driven timer stops or expires at a second point is determined. When the timer stops or expires at the second point, a timer value is compensated for with consideration of a time difference between the first point and the second point. A timer for the data loss of the first point is restarted based on the compensated timer value. Therefore, a delay of a retransmission request time for lost data in an RLC (Radio Link Control) layer may be minimized.

  • Wire bonding joint structure of joint pad, and method for preparing the same
    Patent number: 8729395
    Abstract: A wire bonding joint structure of a joint pad in which electroless surface treatment plating layers of joint pads configured by a nickel layer/a palladium layer/a gold layer are connected to each other by a metal wire and when the metal wire is joined to the electroless surface treatment plating layer, a depth of the wire bonding pad formed by wedge deformation is 1.0 m or more. The electroless surface treatment layer of the joint pad can lower strength and hardness of the wire bonding pad of which the surface is treated to improve follow-up capability between a gold wire and the bonding pad, such that a joint area between the gold and the bonding pad is maximized, thereby increasing joinability at the wire bonding finish process by wedge pressure and greatly improving wire bonding workability.
