Entity according to claim 14, characterized in that said link is an uplink. La liaison est alors une liaison descendante ou “downlink” en anglais.
Minimum-shift keying — Wikipédia
CH Cous format text: Arrangement for the optimization of the data transmission via a bi-directional radio channel. Method according to one of claims 3 and 4, characterized in that the number of bits of the transmitted blocks being a function of the modulation scheme used, the raw data rate is determined for a given modulation scheme corresponding to said modulation reference, what may be the modulation scheme used.
Method according to one of claims 5 and 6, characterized in that said reference modulation is lower spectral efficiency.
LU Free format text: The coding is usually operated on sequences of information bits or blocks. REF Ref document number: Therefore, to have a better quality indicator, it may be best to consider the relative net flow, ie the ratio of net flow of crude throughput.

System according to claim 11, characterized in that said link is an uplink. According to another feature, said link is an uplink.
MK05 Ref document number: According to another feature, said quality is assessed from the relative net flow, that is to say the ratio between the net rate and gross throughput.
Other objects and features of the present invention will become apparent on reading the following description of exemplary embodiments, taken in conjunction with the appended figure for schematically illustrating a radio link whose quality is evaluated using a method according to the invention.

Different techniques for optimizing the performance of these systems can be used, such as including the following techniques: Equivalently, this expression can be written: The mobile communications coure system has a link connection. The connection is then a downlink or “downlink” in English. Method and apparatus for scrambling information bits on a channel in a communications system.
Algorithms such as for example, link adaptation algorithms or cell reselection is generally implemented in the network, the network can thus himself determine the BLER, for the downlink direction, without it being necessary that the mobile station defers to the network the value of BLER it determines. A serious illness deprive himd of the ability to move about Pag.
In particular, protection against transmission errors is obtained by means of coding such as a particular error correcting coding for introducing redundancy into the information transmitted.
Choosing as a reference modulation modulation lower spectral efficiency that is to say for which the number of transmitted bits per symbol is the lowest as the GMSK modulation in the EGPRS system, this latter expression Furthermore, an additional advantage is that it can take into account that the performance is better when a block is received correctly by using a high spectral efficiency modulation that when a block is received correctly by using a low modulation spectral efficiency.

For a description gsmk these systems, reference may be made for example to document “GSM EP Ref country code: Another object of the present invention is a mobile station, said mobile station being essentially characterized in that it comprises means for assessing the quality of a radio link, from the net flow transmitted over said link.
However the cpurs indicator according to the invention could also be used for other purposes such as the adaptation of such link. The coding rate is defined as the ratio of the number of information bits to be transmitted on the number of bits transmitted or coded bits. However, high moulation efficiency requires good radio conditions, otherwise the quality of service is degraded. Variable rate forward error correction for enabling high performance communication.
Performance analysis of GMSK Carrier synchronization loop phase detector at very low SNR
A method for selecting a combination of ciurs and channel coding schemes in a digital communication system. In these systems, several treatments are required to make information to be transmitted in a form suitable for transmission over the radio interface.
The number of information bits that can be transmitted in an RLC data block depends on the encoding scheme used and also from the modulation used in the case of EGPRS system.
