Problems solved by technology

[0007] In order to overcome the problem that the overhead of the RLC PDU layer header is too large in the communication technology, and the entire content of the entire RLC PDU must be transmitted to cause waste of wireless resources, the present invention provides a method and device for concatenating service data units of the radio link control layer , RLC PDUs are adaptively concatenated to generate protocol data units, and the concatenation of RLC SDUs is jointly determined according to the TB size selected by the MAC layer scheduling entity and the preset RLC PDU size threshold

Abstract

The invention provides a serial method of a wireless link control layer service data unit, which includes steps as follows: A media access control layer calculates the size of a transmission block according to a predetermined scheduling algorithm and notifies the wireless link control layer. The wireless link control layer judges that whether the sum of the length of the wireless link path control layer service data unit, the overhead of the wireless link control layer and the overhead of the media access control layer is larger than the size of the transmission block. Whether to implement serial treatment is ensured according to the judged result. And according to the protocol data unit which is provided by the wireless link control layer, the media access control layer judges that whether the sum of the length of the service data unit of the media access control layer and the overhead of the media access control layer is smaller than the size of the transmission block. The transmission block is produced according to the judged result.

Description

technical field [0001] The present invention relates to the technical field of digital mobile communication, and more specifically, relates to a method for concatenating service data units of a radio link control layer in a radio communication system. Background technique [0002] In the wireless access network of the third-generation mobile communication system supporting High Speed ​​Downlink Packet Access (HSDPA), the Automatic Repeat Request (ARQ) entity is located in the Radio Link Control Layer (RLC) of the Radio Network Controller, and the Hybrid Automatic Repeat The transmission request (HARQ) entity is located in the medium access control layer (MAC) of the base station, and is respectively responsible for the transmission / retransmission operation of the protocol data unit (PDU) generated by the corresponding protocol layer. Data packets need to be segmented / concatenated / stuffed at the wireless network controller, and multiplexed / demultiplexed at the base station. ...
