摘要： Disclosed is a method of generating a detection signal for detecting energy in a spread-spectrum signal, comprising: de-spreading the spread-spectrum signal by applying a predetermined spreading code to obtain a sequence of de-spread signal symbols (202A-202D); accumulating a number of said signal symbols to obtain a single detection signal. The accumulation includes: obtaining a first and a second subset of said de-spread signal symbols, wherein the symbols of the first subset have values that are known to the receiver or at least known to be the same for all symbols of the first subset, and wherein the symbols of the second subset have unknown values; coherently accumulating the symbols of the first subset to obtain a first partial detection signal (203A, 203B, 203C); non-coherently accumulating the symbols of the second subset to obtain a second partial detection signal (204A, 204B, 204C); and combining the first and second partial detection signals to obtain the single detection signal (208).

摘要： A Radio Network Controller (RNC) is configured to send Radio Resource Control (RRC) messages to a mobile station using a selected downlink channel. Depending on the mobility rate of the mobile station, the RNC is configured to configure a signaling connection to use either a first downlink channel or a second downlink channel for transmitting the RRC messages. According to one embodiment, the RNC selects a dedicated channel when the mobile station has a high mobility rate, and selects a shared channel when the mobile station has a low mobility rate.

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： Information systems, detectors, and methods for a communication link, such as the downlink of a cellular telephone system, reduce the problem of uplink transmit power peaks when the uplink is out of synchronization (OoS). One method of indicating that a first link to a communication node is OoS includes the step of including an OoS signal in signals that are sent by the node on a second link. The OoS signal includes at least one data bit transmitted by the node that indicates that the first link is synchronized or OoS. A method of determining that a first link to a communication node is OoS includes the step of detecting an OoS signal in signals that are sent by the node on a second link. The OoS signal includes at least one data bit that indicates that the first link is synchronized or OoS.

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 chapels 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 below 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 outerloop power control algorithm can be implemented at a mobile station level, base station level or radio network controller level.

摘要： The excess signal-to-interference ratio (SIR) or the like of a communication channel is determined by repeatedly decoding received information with successively reduced effective SIR. The step size in an outer power control algorithm, for example a Jump Algorithm, such as that commonly used for transmit power control in communication systems can then be adaptively adjusted based on the excess SIR, enabling faster convergence. Decoder hardware already present in a user equipment, such as a mobile telephone or other receiver, can advantageously be used.

摘要： Method and system are disclosed for providing advanced RAKE delay control in wireless communications systems. The RAKE delay control method and system of the invention is capable of tracking presently known paths over time and merging the tracking results with new path searcher results. The invention is particularly suitable for devices where the resources (e.g., computational load, power) available for detecting the multipath components are limited. The result is a resource efficient architecture for positioning the RAKE fingers to best extract the signal power available in the channel and to utilize the inherent diversity due to the multipath nature of the signal.
