Document Type and Number:
WIPO Patent Application WO/2003/081837
Kind Code:
A1
Abstract:
The present invention discloses an automatic repeat request ARQ error control method for different channels and the apparatus thereof, characterized in that the stop and wait ARQ methods in different channels are independent and the data packets are transmitted in parallel. With the help of the relationship between the sequence numbers of the data packets to be sent and resent, it is decided whether the transmission side should send these data packets. The reception of data packets in the reception side is ensured by increasing the sequence number. With the error control method of the present invention, the disordered transmission of data packets in the DSW technology can be implemented by setting the sequence number, which can be applied to the wireless communication system for high speed packet data service and increase the availability of the channel resource.
