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.
More the spectral efficiency is high, and this number is high. ES Free format text: In addition, in the case where the quality evaluation is performed in the network, the quality assessment may be performed in one or the other constituent of such a network entities referred to herein as radio network entities mobilesuch as: GR Free format text: MC Free format text: CH Ref legal event code: Retrying p nikitin pdf.

R Ref document number: La mercanca y el trabajo creador de las mercancas: There are also other cases where BLER is not a satisfactory criterion, especially when using the technique called incremental redundancy or “incremental redundancy” in English.

The receiver 2 comprises, in the example illustrated: Methods for forward error correction coding above a radio link control layer and related apparatus.
DK Free format text: System and method for measuring channel quality information in a communication system. 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.
Various modulation techniques are known, characterized by the spectral efficiency, that is to say their ability to transmit a higher or lower number of bits per ckurs, for the same allocated frequency band.
According to another feature, the transmitted blocks or radio blocks, which may include one or more blocks or data blocks, depending on the modulation scheme used, the ratio between the net rate and the raw bit rate is obtained by calculating: NL Free format text: If the quality assessment is carried out in the network: In addition, the following radio criterion the invention has been mainly described in the case where the re-transmission technique is used.
BLER is the rate of data blocks received incorrectly.
Method and base station for controlling link adaptation and packet scheduling in high speed downlink packet access HSDPA radio system. 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.
The state, correct or not, the received blocks is reported by the receiver to the transmitter by means of said acknowledgment messages ACK or to “Acknowledgment” in English or non-acknowledgment NACK or, for ” non-Acknowledgment “in English. Net R net debit however, may not be the most appropriate criterion for R net depends not only on the radio conditions but also the allocated radio resources for radio conditions data, plus the allocated radio resources, the greater net R is high.

The present invention therefore proposes to use a criterion related to the net debit. The bit sequence mpdulation in 20ms over the radio interface is called radio block. Another object of the present invention is a network entity of mobile radio, this entity being essentially characterized in that it comprises means for assessing the quality of a radio link, from the net flow transmitted over said link. Non-correctly received blocks can be blocks in which errors are detected by means of a code error detectoror can not be corrected by means of an error correcting code.

La liaison est alors une liaison descendante ou “downlink” en anglais. This technique is a technique for re-transmission more elaborate and more efficient than that mentioned above. A PDCH is a physical channel corresponding to a time slot per frame a frame comprising eight time slots and a frequency or a set of frequencies where the frequency hopping technique is used. Different techniques for optimizing the performance of these systems can be used, such as including the following techniques: Method according to one of claims 5 and 6, characterized modulatin that said reference modulation is lower spectral efficiency.

According to another feature, modulatipn ratio between the net rate and the raw bit rate is obtained by calculating: The number Courrs i c depends on the modulation scheme applied in the i-th transmitted block. Another treatment consists of modulation, to obtain a carrier analog signal information to be transmitted.
A method according to claim 3, characterized in that the transmitted blocks or radio blocks, which may include one or more blocks or data blocks, depending on the modulation scheme used, the ratio between the net rate and the raw bit rate is obtained by calculating:
