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

Embodiment Construction

[0024] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] figure 1 It is a flowchart of a method for concatenating RLC layer service data units according to the present invention. Such as figure 1 As shown, the concatenation method of the radio link control layer service data unit includes the following steps:

[0026] (1) Step S102, the medium access control layer calculates the size of the transport block according to a predetermined scheduling algorithm, and notifies the radio link control layer.

[0027] (2) Step S104, the radio link control layer judges whether the sum of the length of the radio link control layer service data unit and the header overhead of the radio link control layer and the header overhea...

Abstract

The invention provides a serial device of a wireless link control layer service data unit, including a calculation module which is arranged above a media access control layer and used for calculating the size of a transmission block according to a predetermined scheduling algorithm and notifies the wireless link control layer. The device still includes a serial module which is arranged above the wireless link control layer and is used for judging that whether the sum of the length of the wireless link 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. The serial module determines that whether to implement the serial treatment according to the judged result. The device also includes a transmission block generation module which is arranged above the media access control layer and is used for judging that whether the sum of the length of the media access control layer service data unit and the overhead of the media access control layer is smaller than the size of the transmission block. And 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 particularly relates to a device 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. ...
