Title: Data transmission confirmation in a wireless communication system
Inventor: WU FRANK CHI-HSIANG
IPC: H04L29/06
Filed: 2003-01-30
Abstract: The present invention provides a data discard signaling procedure in a wireless communication system. A Radio Link Control (RLC) provides PDCP in-sequence confirmations. The in-sequence confirmation means that confirmations shall be delivered to PDCP in the same order as PDCP PDUs submitted by PDCP. The sending RLC Acknowledge Mode (AM) entity confirms PDCP Service Data Units (SDUs) with Sequence Numbers (SN) that are positively acknowledged by the peer receiving RLC AM entity. In this way, PDCP PDUs and associated PDCP SDUs with SNs not positively acknowledged will not be deleted by the sending PDCP entity. Another solution provided by the present invention is when the SN for a PDCP SDU carried in a PDCP PDU confirmed by the RLC is larger than the smallest SN for the unconfirmed PDCP SDU, PDCP shall not delete this PDCP PDU and its associated SDU confirmed by RLC until the SN for this PDCP SDU indicated by this confirmation is the smallest or earliest SN. Therefore, the present invention provides a procedure for confirming data transmission which efficiently eliminates problems existing in lossless SRNS Relocation and PDCP Sequence Number synchronization and improves wireless communication system performance.

Title: Semiconductor device and its manufacture
Inventor: OKADA TETSUYA
IPC: H01L29/47
Filed: 2003-05-01
Abstract: A problem in a conventional Schottky barrier diode is that VF and IR characteristics thereof are in a trade-off relation so that while a low VF is realized an increasing of a leakage current becomes unavoidable. In this invention, a plurality of regular hexagonal P+ type semiconductor regions are provided in a Schottky junction region. Since the intervals therebetween are equal, when a reverse voltage is applied depletion layers extend from the P+ type semiconductor regions and cover the epitaxial layer up. That is, the leakage current generated at the Schottky junction interface which leaks toward the cathode side can be shielded by the depletion layers. Consequentially, the trade-off relation between VF and IR exists no more, as even the leakage current generated is high, it can be shielded by the depletion layers, therefore a low VF can be realized without considering the IR.
