Packet multiplexing method in wireless communication system

Abstract

The data package multiplexing method for a wireless communication system with both ARQ and HARQ entity on BS media access control layer comprises: pre-defining the transmission block size, then: according to set scheduling algorithm, determining the user device with available wireless resource and service data in relative business PRI sequence for next TTI, and selecting corresponding transmission block size; for every user device, segment processing the service data unit according to selected size, and adding head message to generate ARQ protocol data unit; multiplexing the said ARQ unit, and adding head message to generate a HARQ protocol data unit. This invention supports length-variable protocol data unit.

Description

A data packet multiplexing method in a wireless communication system technical field The invention relates to the technical field of digital mobile communication, in particular to a method for multiplexing data packets in a wireless communication system. Background technique In the radio access network of the third-generation mobile communication system, the ARQ entity is located in the radio link control layer of the radio network controller, and the HARQ entity is located in the medium access control layer of the base station, and are respectively responsible for the transmission of the protocol data unit generated by the corresponding protocol layer. / Retransmit operation. Data packets need to be segmented / concatenated / stuffed at the wireless network controller, and multiplexed / demultiplexed at the base station. Taking the downlink data packet as an example, in the radio link control layer of the radio network controller, the service data unit from the upper layer pro...

Problems solved by technology

In the third-generation mobile communication long-term evolution system, the ARQ entity and the HARQ entity are located in the base station of the wireless access network, and the two-layer entities can know the real-time physical channel conditions in time, so the segmentation / concatenation / filling processing can be performed The transmission block size selected based on the real-time scheduling results, but there is still a lack of a relatively complete solution
