In a method for configuration of a compressed mode in a mobile radiocommunication system, a configuration of a compressed mode defined using the parameters for the compressed mode. The parameters include a transmission gap length (TBVL) and a transmission gap pattern length (TGPL). The 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. 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 so that two transmission gaps occur in two of the positions, the closest of which overlap each other with an overlap duration long enough to carry out a measure.

Method for setting a transmission quality target value for power control in a mobile radiocommunication system

A method of controlling transmission power in a mobile radio system in which a power control algorithm controls transmission power as a function of a transmission quality target value, wherein a target value is varied to compensate the effects of a compressed transmission mode in which transmission is interrupted during transmission gaps and the bit rate is increased correspondingly to compensate the transmission gaps. The target value variation includes a first component for compensating the effects of the increase in bit rate and a second component for compensating other effects of transmission gaps. A corresponding anticipated variation of the transmission power is applied, and the anticipated variation of the transmission power corresponds to an approximate value of the target value variation obtained by a process of approximation from the second component.

Method of controlling transmission power in a mobile radio system

A first rate matching stage matches a number of input bits coming from a transport channel including a high-speed downlink shared channel (HS-DSCH) of a block of data bits to be transmitted from a base station of a communications network to one or more pieces of user equipment (UE) to a selected number of intermediate bits as determined by the buffer size management system. A virtual buffer stores the selected number of intermediate bits. A second rate matching stage matches the selected number of intermediate bits to a number of output bits equal to a maximum number of bits that is guaranteed to be transmitted by a set of high-speed physical downlink shared channels (HS-PDSCH) associated with the transport channel in a given time interval without adding bits.

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 Xin accordance with a selected sequence in which the value of the redundancy parameter Xused for the first block transmission is selected to give priority to transmitting systematic bits.

A method of managing processing resources in a mobile radio system in which a first entity manages radio resources and corresponding processing resources provided in a separate second entity. The second entity signals to the fist entity its overall processing capacity and the amount of that overall processing capacity required for allocating radio resources for different bit rate values. The first entity then updates the capacity credit on each allocation of radio resources as a function of the corresponding bit rate.

A device controls an outer loop () for controlling the adjustment of a primary target value (SIRc) of an inner power control loop in a multiservice telecommunications installation. The external control loop () feeds the inner loop with the primary target value (SIRc) corresponding to a service. The device includes control means () adapted, if there are at least two different services in the installation, to select one service dynamically and as a function of a selected criterion so that the outer loop can determine a primary target value (SIRc) corresponding to the selected service.

Method of and a device for controlling an outer loop for adjusting the target value of an inner power control loop

For radio transmission on the downlink the transmit power must be calculated also for that signals which shall be sent on the common physical channel, known as secondary common control physical channel (SCCPCH), in the Frequency Division Duplex mode of the Universal Mobile Telecommunications System. In the case where no data is transmitted in a SCCPCH frame, the transmit power level is not defined for SCCPCH data bits. Therefore the well-known adaptation of the TFCI and Pilot powers cannot be applied. The solution proposed here is to set or change the transmit indicator power of the TFCI indicator bits in dependence from a virtual reference power which is calculated from parameters comprising first power values preferably defined by the radio network controller (CRNC) or comprising second power values representing an average of that transmit powers which have been used to transmit that data within at least two of the preceding frames. The virtual reference power can also be a fixed power value which is signalled by the radio network controller or which is a hard-coded value stored in the base station. An advantage of is that the TFCI and the Pilot powers can both be calculated very easily by adapting them to the virtual reference power in the some manner as this is done in the normal case with respect to the data bit power.

A method of controlling transmission power in a mobile radiocommunications system, in which at least two distinct physical channels transmitted by a single transmitter have their respective transmission powers controlled by a power control algorithm as a function of a target value for transmission quality (SIR target) correspond to a first channel which is taken as a reference, and in which, for a second channel, a transmission power offset (PO) relative to the first channel is applied, where necessary, the method being essentially characterized in that when there is a change in the required transmission conditions, a variation having a first value (&#x394;1) is applied to said target value (SIR target), and a variation having a second value (&#x394;2) is applied to said power offset (PO) so that said first channel has its transmission power changed by said first value and the second channel has its transmission power changed by a value equal to the difference (&#x394;1&#x2212;&#x394;2) between said first and second values.

Method of managing processing resources in a mobile radio system

The present invention relates to a method and system for improving the performance of a mobile radiocommunication system, through the use of a power control algorithm. In this invention, the performance of a mobile radiocommunication system is improved by regularly estimating if a certain criterion is met or satisfied, to determine if a power control algorithm should be deactivated or not. The estimation of whether or not the set criterion is met is based on the estimation of a deviation value, which is representative of a deviation between an estimated transmission quality and a target or desired transmission quality. Thus, the present invention aids in avoiding situations in which the power control algorithm would normally be wrongly activated and, therefore, improves the overall performance of the mobile radiocommunication system.
