摘要： A network node that serves a cell in a cellular communication system is operated. An air interface of the cellular communication system is divided up into sequentially occurring frames, each of the frames comprising a plurality of sequentially occurring sub-frames, each of the sub-frames comprising a plurality of sequentially occurring symbols. Operation includes receiving and detecting a request signal transmitted by a device within the cell. Based at least in part on a characteristic of the request signal that is indicative of one or more device capabilities of the device, an associated time/frequency position for transmitting a response signal is ascertained. The response signal is transmitted at the ascertained time/frequency position.

摘要： A method for determining a channel quality index in an OFDM receiver is disclosed. The method comprises receiving signals comprising reference signals from a serving cell and reference signals from neighboring cells; determining signal power of the reference signals from the serving cell and signal power of the reference signals from detected neighboring cells; and determining carrier-to-interference ratio to be the ratio between the signal power of the reference signals from the serving cell and the signal power of the reference signals from the detected neighboring cells. Carrier-to-interference ratio is used for adapting physical layer properties and/or for deciding on handover. A computer program and apparatuses for implementing the method are also disclosed.

摘要： Methods and devices for detecting a symbol in a radio channel and for cell identification are disclosed. 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： Wireless transmissions from a user of a spectral resource are sensed by operating receiver equipment within a user equipment to receive signals within a given bandwidth around a given carrier frequency. If the user equipment is not readily capable of analyzing the received signals to ascertain whether the signature pattern of the user is present in the received signals, then it works cooperatively with a remote unit to analyze the received signals to ascertain whether a signature pattern of the user is present in the received signals. Results of the analysis are reported to a main node. The remote unit can provide software to the user equipment and/or perform at least part of the analysis for the user equipment.

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 multi-branch OFDM receiver combines diversity signals received over different receiver branches using interference rejection combining. The receiver generates first channel estimates associated with a serving base station, second channel estimates associated with at least one non-serving base station, and a time offset between the serving base station and non-serving base station. The receiver computes a noise covariance matrix based on the second channel estimates and the time offset, and then combines the diversity signals received over different branches using the first channel estimates and the noise covariance matrix.

摘要： A bumper beam for a vehicle has a hat shaped profile with the crown (12-14) facing the vehicle and has a cover (17) that gives the bumper beam a closed profile. The bumper beam has two mountings (20, 21) that usually are adapted to be fitted to the side rails of the vehicle. The cover is extended on both sides past the mountings, but leaves the outer portions of the hat beam open. The crown of the open portions of the hat beam have a longitudinal indentation (32) and a profile height that decreases towards the ends.
