摘要： Exemplary embodiments of the present invention describe terminal position location methods and systems. Relative powers of nearby spot beams which are generated by array antennas are determined. For example, powers from six neighboring spot beams relative to a center spot beam within which a mobile station is currently operating, can be measured relative to the power of the center spot beam. Using information from these measurements, the mobile stations position can be determined using, for example, an exponential model of the spot beam pattern.

摘要： A diversity scheme for allowing a transmitter/receiver, such as a mobile unit in a mobile telecommunications system, to exchange communication signals with more than one control station, such as a base station or satellite. According to an exemplary embodiment of the diversity scheme, the mobile unit scans for the control channel of a second satellite during idle time slots while communicating with a first satellite during active time slots. Once the mobile unit detects a control channel from a second satellite, the mobile unit stores synchronization information and establishes a communication link with the second satellite if shadowing or other severe fading causes signal quality over a communication link established with a first satellite to fall below a threshold level. The diversity scheme also allows the mobile unit to communicate simultaneously with two satellites, using alternate TDMA frames.

摘要： Demodulation and interference parameter estimation in an OFDM receiver is improved by identifying regions, in a two-dimensional array of time-frequency transmission positions, having related interference parameters, such as resulting from the same pre-coding scheme, transmission rank, transmitting antennas, and the like. An interference measure is estimated for each of a plurality of time-frequency positions. The interference measures are analyzed by considering them as pixels, or picture elements, in a two-dimensional image, and applying image processing algorithms to identify the regions having related interference parameters. The image processing algorithms may include operations such as edge detection, segmentation, and/or clustering. The receiver may perform interference suppression or cancellation such as interference rejection combining of data extracted from signals received within an identified time-frequency region having related interference parameters.

摘要： RAKE-based receivers utilize lattice reduction for improving symbol estimation accuracy. Channel response estimates and received signal streams are transformed from a constellation lattice basis to an integer lattice basis to increase the orthogonality of symbol estimation decision regions. In one embodiment, received signal streams are processed by generating despread signal samples from received signal streams transmitted using different spreading codes. Channel response associated with the different received signal streams is estimated and transformed from a first lattice basis to a second lattice basis having greater orthogonality between decision regions than the first lattice basis. The despread signal samples are aligned to the second lattice and combining weights generated based on the transformed channel response estimate. Symbol estimation decision statistics are generated based on the combining weights and the aligned despread signal samples. Soft bit values are generated for decoding based on the symbol estimation decision statistics.

摘要： The present invention relates to a mobile terminal device, a base station and a method that make it possible to use a channel quality indicator, CQI, reporting format for CQI reporting from the mobile terminal device to the base station, which CQI reporting format depends on a selected transmit antenna configuration. The mobile terminal device is arranged to receive a signal from a number of transmit antennas, which signal includes a number of subcarriers, and to determine the CQI, reporting format for a collection of the subcarriers based on the selected transmit antenna configuration. The mobile terminal device is further arranged to determine a number of CQI values relating to said subcarriers in accordance with the determined CQI reporting format and to transmit the CQI values to the base station in a feedback signal. The CQI reporting format is adapted to the selected transmit antenna configuration such that the granularity of CQI reporting depends on the selected transmit antenna configuration.

摘要： A base station and method are described herein that vertically sweeps an antenna beam within a cell to improve the signal quality at scheduled times for a user terminal located within a coverage area of the cell. In one embodiment, the method improves a signal quality for a user terminal by: (a) vertically sweeping a beam within a cell coverage area to vary a signal quality at scheduled times for the user terminal located within the cell coverage area; and (b) performing one or more scheduling functions while taking into account variations in the vertical sweep of the antenna beam. For instance, the scheduling function(s) can include a link adaptation function, a resource allocation function, a user admittance/dropping function, a handover function, and/or a hybrid automatic repeat request function.

摘要： A mobile terminal measures interference over multiple measurement periods and generates interference probability data based on the statistical distribution of the interference measured. The interference probability data may describe, for example, the probability of each possible level of interference expected at the mobile terminal. The mobile terminal derives channel quality information as feedback to a base station based on this interference probability data (e.g., when noise at the mobile terminal falls below a threshold). In one embodiment, the mobile terminal does so by estimating from the interference probability data the probability of successfully receiving a transmission if certain feedback information is reported. Derived in this way, the feedback information more reliably indicates interference likely present at the mobile terminal when the base station sends the transmission. Accordingly, the base station controls the transmission based on the feedback information, and in some embodiments, also based on the interference probability data.
摘要翻译：移动终端在多个测量周期内测量干扰，并根据所测量的干扰的统计分布产生干扰概率数据。干扰概率数据可以例如描述在移动终端处预期的每个可能的干扰水平的概率。移动终端基于该干扰概率数据（例如，当移动终端处的噪声低于阈值时）将信道质量信息作为对基站的反馈导出。在一个实施例中，移动终端通过根据干扰概率数据估计在报告某些反馈信息时成功接收传输的概率来做到这一点。以这种方式，反馈信息更可靠地指示当基站发送传输时可能存在于移动终端的干扰。因此，基站基于反馈信息来控制传输，并且在一些实施例中也基于干扰概率数据来控制传输。
