Abstract: A method of locating mobiles via a dynamic base station. The method includes transmitting a first wireless signal from the dynamic base station at a first time, and receiving the first wireless signal at the mobile. The method also includes transmitting a second wireless signal from the mobile in response to receiving the first wireless signal, and receiving the second wireless signal at the dynamic base station at a second time. The method also includes determining a time difference between the first time and the second time, determining an angle of arrival of the second wireless signal, and locating the mobile based on the angle of arrival and the time difference.

Abstract: The present invention is related to a method and apparatus for reducing antenna correlation between multiple antennas. A transmitter generates at least two beams with a plurality of antennas. The generated beams are spatially separated to point away each other. Therefore, the transmitted signals travel through different channel conditions and arrive at a receiver mutually uncorrelated. The beams may be generated by antennas having different antenna pattern, or by an array antenna. The beams may be polarized differently. The schemes may be implemented on a subcarrier basis in an orthogonal frequency division multiplexing (OFDM) system. Trellis coded mapping may be utilized for adjacent symbols to be mapped to antennas with low correlation.

Abstract: A method and system is disclosed for enhancing reception of wireless communication signals. A beam pattern including at least one set of beams is generated. Where the beam pattern includes at least two sets of beams, the beam sets may be offset with respect to each other and alternated to enhance reception. Beams may be selected for data processing based on a signal-to-noise ratio (SNR) and may be maximal-ratio combined where signals from a single WTRU are detected within more than one beam and are used for data processing.

Abstract: A circuit for use in a broadcast transmitter for adaptively compensating for carrier signal distortions caused by amplitude modulating an RF carrier signal. The circuit includes a modulator/amplifier network that receives an RF carrier signal and modulates it by a received amplitude varying signal to obtain therefrom a modulated carrier signal which may exhibit distortions caused by the amplitude modulating of the RF carrier signal. A digitally adaptive corrector precorrects the amplitude varying signal prior to application thereof to the network to compensate for any modulated carrier signal distortions. This includes a digital processor that provides signal correction as a function of digital samples representing amplitude variations of the modulated RF carrier signal.

Abstract: Apparatus, and an associated method, for facilitating communications in a non-ideal communication system. Data to be communicated by a sending station to a receiving station selectably utilizes an open-loop transmit diversity scheme and a closed-loop transmit diversity scheme. A determiner at the receiving station determines closed-loop feedback information and a determiner thereat also determines the reliability to be associated with such feedback information. The reliability indications and the feedback indications are returned to the sending station. And a selector positioned thereat selects in what manner to utilize open-loop and closed-loop transmit diversity for subsequent communications.
