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 time-division multiple access (TDMA) base station is disclosed for preserving across-slot signal continuity of signals transmitted in different directions on a given frequency. The base station includes a multi-directional antenna for radiating signals. A processor is operatively coupled to the antenna for generating a first data signal for a first time slot of a TDMA frame including a first pre-determined symbol pattern and a second pre-determined symbol pattern, for generating a second data signal for a second time slot of the TDMA frame including the second predetermined symbol pattern, and for communicating the first data signal and the second data signal to the antenna such that the first data signal is radiated in a first direction and the second data signal is radiated in a second direction. The first data signal is modulated at a first phase for transmission in the first time slot at a first power level in the first direction on the given frequency. The second data signal is modulated at a second phase for transmission in the second time slot at a second power level in the second direction on the given frequency.

摘要： A satellite broadcasts radio programs to mobile and fixed receivers at various locations. Ground stations supplement the satellite broadcasts in areas where the satellite signal may be shadowed. Likewise, the satellite signal supplements the terrestrial transmissions in areas with marginal terrestrial signal strength. Ground stations and a satellite transmit the same digital symbol stream over a same frequency spectrum. The symbol streams arrive in each service area of the ground stations with a relative delay that is within a window for which a receiver is adapted to decode efficiently. Spectral efficiency is achieved by allowing the ground stations to share the same frequencies as the satellites.

摘要： A method and apparatus for efficiently providing a large volume of channel feedback, e.g., for OFDM MISO and MIMO systems, is described herein. To that end, a mapping unit in an OFDM transceiver maps channel feedback values, e.g., received reference signal values or channel estimates derived therefrom, on a one-to-one basis to individual transmission subchannels. More particularly, the mapping unit maps a feedback value, e.g., the received reference value or a channel estimate derived therefrom, to a single transmission subchannel of an outgoing OFDM signal. For example, the mapping unit may map the feedback value to an input of a frequency transform unit, such as an inverse discrete Fourier transform unit, to map the feedback value to a single transmission subchannel comprising an OFDM transmission subcarrier. The OFDM transceiver transmits the outgoing OFDM signal to the remote transceiver to provide the feedback value to the remote transceiver.
摘要翻译：本文描述了用于有效地提供大量信道反馈的方法和装置，例如用于OFDM MISO和MIMO系统。为此，OFDM收发器中的映射单元将信道反馈值（例如，接收到的参考信号值或从其导出的信道估计）一一对应地映射到各个传输子信道。更具体地，映射单元将例如所接收的参考值或其导出的信道估计的反馈值映射到输出OFDM信号的单个传输子信道。例如，映射单元可以将反馈值映射到诸如逆离散傅立叶变换单元的频率变换单元的输入，以将反馈值映射到包括OFDM发送子载波的单个发送子信道。 OFDM收发器将输出的OFDM信号发送到远程收发器以向远程收发器提供反馈值。

摘要： The technology in this application solves these problems (and others) and meets the desirable goals identified above (and others). The technology spreads a signal over an available discontinuous spectrum, such as a radio frequency band, so that the spread signal only occupies the non-contiguous spectrum. In this way, CDMA transmission and reception can be used in a fragmented or non-contiguous spectum that otherwise would not be useable for direct sequence spreading. Spreading over non-contiguous portions of spectrum is preferably performed without producing unacceptable interference in portions of unavailable spectrum located between the allowed spectrum. By avoiding unacceptable interference in portions of unavailable spectrum located between the allowed spectrum, the unavailable spectrum may be used by other users or services.

摘要： The invention comprises using beamforming antenna to coherently transmit an information signal to a receiver using two or more directional beams. In one embodiment, the phase and timing of the information signals carried by each directional beams are adjusted such that the signals arrive synchronously at the mobile terminal. Time synchronization may be obtained by delaying signals transmitted on selected directional beams to compensate for different propagation delays, or by preconditioning and filtering the signals using a channel coefficient matrix.

摘要： A mobile communication system comprises a plurality of cells, with each cell including a network of microstations distributed more or less uniformly throughout the cell. A central controller connected to the network of microstations selects a group of microstations in the vicinity of the mobile terminal to transmit information to the mobile terminal. The selected microstations in the active set for a given mobile terminal is continuously updated as the mobile terminal moves through the network of microstations to form a virtual cell that follows the mobile terminal through the network. Transmission conflicts between two mobile terminals is avoided by inhibiting transmissions from an active microstation to at least one of the co-channel mobile terminals when a transmission conflict is detected.
