Example Embodiment

[0030] In order to facilitate the understanding of the present invention, the common technical terms of the present invention are explained as follows:

[0031] The Transport Format (TF) is used to define the format for sending data from the MAC layer to the physical layer, which is divided into a semi-static part and a dynamic part. The semi-static part changes only when the channel is configured and released. The dynamic part includes the length of a single transmission block, the total length of the transmission block, and the TTI of the transmission block. When the length of a single transport block is fixed, the TF can be determined as long as the number of transport blocks is determined for each TTI.

[0032] Transport Format Set (TFS, Transport Format Set) is a set of TFs that can be used on a certain channel. The semi-static part of TF in TFS is the same, and the dynamic part can be different.

[0033] Transport Format Combination Set (TFCS, Transport Format Combination Se...

Abstract

The invention relates to a method for improving the wireless resource utilization of special channel, belonging to the network communication technique. Wherein, it is completed by MAC layer; MAC checks the real emitted data amount and the useful TF, at each TTI; if the transmission block number of useful TF is equal to the real emitted data block number, selecting said TF; or else, selecting two TF whose real emitted data block numbers DataNum approach the transmission block number of all useful TF most, to be recorded as TFA and TFB, while TFA> DataNum>TFB; when there is no TFA, TFB is the selected result; when there is TFA, judging if (DataNum-TFB)/(TFA- TFB)<LIMIT, and TFB is the selected result; or else, the selection result of TF is TFA; the transmission block number filled by MAC is as PAD=TFA-DataNum. Said invention can make the service data use larger TF, to reach higher wireless resource utilization.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for improving the utilization rate of dedicated channel wireless resources. Background technique [0002] Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) is a third-generation mobile communication system that adopts Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) air interface technology, and is also commonly referred to as a WCDMA communication system. The WCDMA communication system includes a radio access network (RAN, RadioAccess Network) and a core network (CN, Core Network). Among them, the RAN implements all wireless-related functions, and is generally also called Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network). [0003] The wireless interface of UTRAN is divided into physical layer, data link layer and network layer, wh...
