Abstract

The invention provides a method for concatenating service data units of a radio link control layer. The method includes the following steps: the media access control layer calculates the size of the transmission block according to a predetermined scheduling algorithm, and notifies the radio link control layer; the radio link control layer judges the length of the service data unit of the radio link control layer and the radio link control layer Whether the sum of the layer header overhead of the layer and the layer header overhead of the media access control layer is greater than the size of the transmission block, determines whether to perform concatenation processing according to the judgment result; and the media access control layer according to the protocol data provided by the radio link control layer The unit judges whether the sum of the length of the service data unit of the media access control layer and the layer header overhead of the media access control layer is smaller than the size of the transport block, and generates a transport block according to the judgment result.

Description

Technical field [0001] The present invention relates to the technical field of digital mobile communication, and more specifically, to a method for concatenating service data units of a wireless link control layer in a wireless communication system. Background technique [0002] The third-generation mobile communication system supports high-speed downlink packet access (HSDPA) in the radio access network, 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 media access control layer (MAC) of the base station, and is responsible for the transmission / retransmission of the protocol data unit (PDU) generated by the corresponding protocol layer. Data packets need to be segmented / serialized / filled at the radio network controller, and multiplexed / demultiplexed at the base station. [0003] In the following, the following data pa...
