Title: Arq transmission and reception methods and apparatus
Inventor: SEIDEL EIKO
IPC: H04W28/04
Filed: 2002-08-22
Abstract: PURPOSE: A transmitter and a receiver, and corresponding methods for ARQ(Automatic Repeat reQuest) are provided to be capable of allowing flexible timing of ACK/NAK messages without signaling overhead. CONSTITUTION: Data packets are repetitively transmitted to the receiver. Simultaneously, the transmitter receives on the feedback channel data(415) that include ACK/NAK messages. Therefore, the transmitter analyses the received data of each sub-TTI for extracting the acknowledgement message from one of the predefined ACK/NAK time instances(420,430). A controller of the transmitter determines the sub-TTI that has been used for transmitting the acknowledgement. The controller determines from which mobile station the ACK/NAK signal has been received and to which data packet this signal is related(440). Then, the controller determines whether a positive or negative acknowledgement message has been received(450), and if the respective data packet is not decoded by the respective mobile station, retransmission is performed in compliance with the ARQ scheme requirement(460).

IPC: H01M10/44
Filed: 2002-09-18
Abstract: PURPOSE: To provide a power circuit which is excellent in use efficiency of a chemical battery and besides is resistant to intermittent change of a load current. CONSTITUTION: In odd-numbered load burst periods, load L is driven by the power accumulated in a capacitor 16. In even-numbered load burst periods, the load L is driven by the power accumulated in a capacitor 17.
