Problems solved by technology

[0005] In general, the problem caused by compressed mode is that in order to obtain the same quality of service during compressed transmission, a higher transmission power is required, which will cause greater interference to other users
The main disadvantage of this method is that it is only suitable for non-real-time services where long delays are tolerated

Embodiment Construction

[0076] According to the invention, the size of the multiplex frame in compressed mode is reduced by improving the segmentation step (112, 122). Throughout the description, this method will be referred to as unequal segmentation per multiplex frame.

[0077] In practice, in defined third generation telecommunication systems, the segmentation step (112, 122) of each multiplex frame produces data segments with the same size except for one symbol. So, for example, with a 40 ms TTI interval for transmission of 800 encoded symbols, these 800 symbols are divided into four segments of 200 symbols each. Each of these segments is transmitted for one multiplex frame. These four segments all have the same size, which is considered an equal segment. Segmentation is considered quasi-equal if the number of symbols to be transmitted is not a multiple of four, or more generally the number of multiplexed frames in the TTI interval of the coded transport channel, i.e. the data segment resultin...

Abstract

This invention relates to a method for generating a compressed mode affecting a composite channel comprising at least two transport channels. According to the invention, an unequal segmentation step of the transport channels is performed. This segmentation step assigns, for the same transport channel, to each of data segment, a data count determined depending on at least one segmentation coefficient. At least two of said data segments from the same data block having been assigned by said segmentation have distinct data counts This invention is implemented in particular in the field of third generation telecommunication systems for mobiles.

Description

technical field [0001] The invention relates to a method of generating a compressed mode to affect a composite channel comprising at least two transport channels, each of which transmits at least one data block in at least one respective transmission time interval, each of which has a time period dedicated to each of said transmission channels, at least two of said transmission channels having transmission time intervals of different duration, said method comprising the step of time-segmenting the data of at least one of said transmission channels, said The time segmenting step divides said data block into data segments, each said data segment being associated with a time segment of said transmission time interval constituting a period common to the transport channels of said composite channel. The invention is especially suitable for use in the field of third generation mobile communication systems. Background technique [0002] The 3GPP organization (Third Generation Part...
