Abstract:
A method for setting a transmission quality target value for power control in a mobile radiocommunication system, a method wherein: an offset is applied in an anticipated way to said transmission quality target value to compensate for the effects of a compressed mode whereby transmission is interrupted during transmission gaps in compressed frames, and the transmission rate is correspondingly increased to compensate for said transmission gaps, said offset includes a first component intended to compensate for the effects of said transmission rate increase, and a second component intended to compensate for the effects of said transmission gaps, said transmission rate increase applies not only for a compressed frame but for a plurality of frames including said compressed frame, and said second component is not applied for all frames of said plurality of frames, but only for said compressed frame and/or for at least one frame, or recovery frame, following said compressed frame.

A device (D) is dedicated to managing transmission of digital data blocks in High-Speed Downlink Shared Channel (HS-DSCH) downlink transport channel set up between a base station of a communications network and a user equipment. It comprises processing means (MT) adapted, each time that a given block must be transmitted to the user equipment via the transport channel, to select successive values of the redundancy parameter XRV in accordance with a selected sequence in which the value of the redundancy parameter XRV used for the first block transmission is selected to give priority to transmitting systematic bits.

One object of the invention is a method for improving the performances of a mobile radiocommunication system using a power control algorithm, said power control algorithm including an inner-loop power control algorithm for adjusting a transmit power according to received power control commands, said method including: a step of deciding if the transmit power should be increased according to a received power control command (TPC(k)) requiring a power increase, having regard to a cumulative power variation (Δsum(k)) already obtained for last received power control commands, a step of determining a cumulative power variation (Δsum(k)) to be used by said step of deciding, said step of determining including taking into account, further to power adjustments due to said inner-loop power control algorithm, at least one other factor that may affect said cumulative power variation.

Abstract:
A method of managing processing resources in a mobile radio system, in which a first entity manages radio resources and corresponding processing resources, the latter being provided in a second entity separate from the first entity, in which method:the second entity signals to the first entity its global processing capacity, or capacity credit, and the consumption law, or amount of said global processing capacity, or cost, for different spreading factor values,the first entity updates the capacity credit on the basis of the consumption law, andin the case of variable spreading factor and/or variable number of spreading codes, said updating is effected on the basis of a reference spreading factor and/or a reference number of spreading codes.
Abstract:
A method of link adaptation in a mobile radiocommunication system includes selecting a coding and/or modulation scheme as a function of radio conditions represented by an average of radio measurement results. The average includes an average over a relatively short period for rapidly selecting a more rugged coding and/or modulation scheme if radio conditions are degraded rapidly, or an average over a relatively longer period for selecting a less rugged coding and/or modulation scheme or a more rugged coding and/or modulation scheme if radio conditions are not rapidly degraded.
Abstract:
The invention relates to a method for configuration of a compressed mode in a mobile radiocommunication system. Said method comprises a configuration of a compressed mode defined by means of the parameters for the compressed mode, said parameters for a compressed mode including a transmission gap length (TBVL) and a transmission gap pattern length (TGPL). Said transmission gaps are defined in a first transmission time structure specific to a first system and determined relative to a second transmission time structure specific to a second system to permit measures for the second system to be taken in the first system. A configuration of a compressed mode is determined within said method such that, for each reference configuration, if the duration of the TPGL is such that the transmission gaps occur periodically with fixed position in said second structure, then the TGL is selected to be sufficiently large that two transmission gaps occur in two of said positions, the closest of which overlap each other with an overlap duration long enough to carry out a measure.
Abstract:
A signal processing device (D) is installed in a base station (Node B) of a cellular communications network, for example. Said device (D) comprises processing means (MT) adapted to effect preamble detection, as a function of detection parameters, on each signal sent by a requesting terminal (UE) in an authorized access slot and representative of a preamble of a request to access the network associated with an authorized signature. The processing means (MT) are adapted, on receiving a signal requesting access to the network sent by a requesting terminal (UE), to determine a value for at least one detection parameter chosen as a function of at least one selected parameter representative of the radio environment of the requesting terminal so as to adapt the detection of the received signal dynamically as a function of the radio environment of the requesting terminal (UE).
