摘要： A transmitted OFDM signal is detected in a receiver of a wireless communication system. The receiver has at least two receiver branches, each comprising an antenna, a front end receiver, a Discrete Fourier Transform unit, and a channel estimator.

摘要： Methods and apparatus for have frequency offset estimation and cell search in radio communication systems take into account the time-frequency correlation properties of reference and synchronization signals in such systems. This reduces the probability of misdetection of the physical layer cell ID and frequency offset by accounting for time-frequency ambiguities and evaluating correlation signal peaks in the frequency domain, saving signal processing time and making initial cell search considerably faster. Also, lower-grade and hence cheaper oscillators can be used without causing problems in the user's experience with a receiver, such as a cellular telephone.

摘要： A base station reduces interference from user equipment operating in a neighboring cell by monitoring one or more channels of neighboring base stations to receive a signal transmitted by a user equipment that is being served by one of the neighboring base stations, and detecting when a power level of the signal transmitted by the user equipment exceeds a threshold power level. The base station then uses the received signal transmitted by the user equipment to acquire an identifier of the user equipment. The base station then communicates with a network node of the mobile communication system to arrange for it to serve the user equipment itself but in only the uplink direction. The neighboring base station continues to serve the user equipment in the downlink direction in what is now an asymmetrical uplink/downlink connection.

摘要： A base station receives channel quality reports from a plurality of mobile terminals. The channel quality reports from the mobile terminals indicate the signal power of the signals received by the mobile terminals from the base station and one or more interference parameters relating to the power of impairment components contributing to the total impairment of the received signal during a first time interval. The base station computes an estimated channel quality indication for a second time interval subsequent to the first time interval based on expected variations in the powers of the impairment components. The estimated channel quality indication for the second time interval is used by the base station to schedule the mobile terminals and to determine the transmission format.

摘要： A receiver receives and front-end processes a plurality of component carrier signals, each carrier spaced apart in frequency. The digitized, baseband component carrier signals are inspected to determine estimates of timing offsets between the carriers. A control unit selects a first component carrier signal having data scheduled to the receiver. If data is scheduled to the receiver on other component carrier signals, the control unit generates timing and frequency offset adjustment control signals to time-and frequency-align each other component carrier signal having relevant data, to the first component carrier signal. All the relevant component carrier signals are then combined, and a single OFDM symbol, spanning all the relevant component carriers, is presented to an FFT for symbol detection.
