Abstract
A data transmission method for a mobile communication system is disclosed. A data transmission method at a specific protocol layer of a reception end of a mobile communication system includes receiving at least one data block of a specific protocol layer from a transmission end, and transmitting reception status indication information to the transmission end according to a reception status of the data block of the specific protocol layer. As a result, data can be more quickly and effectively transmitted to a destination.
Claims19
A data transmission method at a specific protocol layer of a reception end of a mobile communication system comprising:
- a) receiving at least one data block of a specific protocol layer from a transmission end;
- and
- b) transmitting reception status indication information to the transmission end according to a reception status of the data block of the specific protocol layer.
A data transmission method at a specific protocol layer of a transmission end of a mobile communication system comprising:
- a) receiving first reception status indication information associated with first time information and second reception status indication information associated with second time information from a reception end;
- and
- b) comparing the first time information with the second time information.
A method for transmitting reception status indication information at a specific protocol layer of a reception end of a mobile communication system comprising:
- a) receiving at least one data block associated with a specific protocol layer from a transmission end;
- and
- b) if a transmission period of reception status indication information of the at least one data block has elapsed, determining whether the reception status indication information is transmitted to the transmission end according to a status of a reception buffer.
A method for allowing a specific protocol layer of a reception end of a mobile communication system to periodically transmit reception status indication information comprising:
- receiving at least one data block associated with a specific protocol layer from a transmission end;
- and
- determining whether a timer for measuring a transmission period of reception status indication information of the at least one data block is driven or not according to a status of a reception buffer.
A method for allowing a specific protocol layer of a reception end of a mobile communication system to periodically transmit reception status indication information comprising:
- receiving at least one data block associated with a specific protocol layer from a transmission end;
- and
- periodically transmitting reception status indication information of the at least one data block to the transmission end according to a transmission period variably decided by a status of a reception buffer.
A method for allowing a specific protocol layer of a transmission end of a mobile communication system to retransmit at least one data block comprising:
- receiving first reception status indication information associated with at least one data block transmitted to a reception end from the reception end;
- and
- retransmitting the at least one data block according to the first reception status indication information in consideration of second reception status indication information received from the reception end.
