A signal is received from the radio channel and the signal is filtered by a filter being responsive to the symbol thereby establishing a first signal. A second signal dependent on the noise floor of the received signal is established—whereby a time interval expected to include multi-path components being excluded or suppressed. A third signal being the ratio between the first signal and the noise floor is established, and the presence of the symbol is detected by detecting a peak in the third signal.

摘要： A user equipment (UE) in a mobile communications system is operated in a manner that alleviates or avoids an overload condition in the UE. This involves operating a receiver of the UE to receive one or more data blocks via a channel. In response to a user equipment overload condition being detected, a channel quality indicator (CQI) value is reported to a serving base station, wherein the reported CQI value represents a channel quality that is lower than an actual quality of the channel. The UE is then operated in a manner that is consistent with the reported CQI value. UE overload conditions include overheating, and an inability to process received data blocks at the rate at which they are being received.

摘要： A method for generating a power control command in a transceiver in a wireless communication system, where the method comprises the steps of calculating, at the beginning of a predefined time period, a quality measure reference value, generating, repeatedly during the predefined time period, an estimated quality measure value of a signal received at the transceiver; generating a power control command in dependence of the estimated quality measure value and the quality measure reference value; and generating, a number of times during the predefined time period, a modified quality measure reference value from the quality measure reference value. The step of generating the power control command comprises comparing the estimated quality measure value with the modified quality measure reference value. A power control unit, comprising a quality measure estimator, a calculator, a first controller, a second controller and an inner loop element, is configured to implement the method.

摘要： A telecommunications system for improving quality of service (QoS) to users via the implementation of an extended outer loop power control algorithm. A radio resource manager (RRM) operates to determine the number of channels allotted to users within a network at a certain time. The RRM implements the extended outer loop power control algorithm for each allotted channel, thus determining SIR reference values for each allotted channel the RRM ensures that the SIR reference value for any channel does not fall bellow a predetermined minimum value. The SIR reference value to be used for all channels in use is determined as the highest of all the calculated SIR reference values. The extended outer loop power control algorithm can be implemented at a mobile station level, base station level or radio network controller level.
