摘要： A communication device is described herein that has control (or at least partial control) over which virtual antenna(s) in one or more base stations to use for transmissions. In one embodiment, the mobile phone performs the following steps: (1) receives an antenna subset list (from the scheduling unit) which identifies a configuration of virtual antennas that is associated with the base station(s); (2) uses the antenna subset list to select which virtual antenna(s) in the configuration of virtual antennas to use for transmissions; and (3) sends an antenna selection signal (to the scheduling unit) which contains information that instructs/requests the base station(s)/scheduling unit to use the selected virtual antenna(s) for transmissions.

摘要： A wireless communication receiver improves signal impairment correlation estimation in MIMO/MISO systems by considering different transmit power allocations and different transmit antenna power distributions in its impairment correlation calculations. The receiver may be implemented in according to a variety of architectures, including, but not limited to, Successive Interference Cancellation (SIC) Generalized RAKE (G-RAKE), Joint Detection (JD) G-RAKE, and Minimum Mean Squared Error (MMSE) G-RAKE. Regardless of the particular receiver architecture adopted, the improved impairment correlations may be used to calculate improved (RAKE) signal combining weights and/or improve channel quality estimates for reporting by receivers operating in Wideband CDMA (W-CDMA) systems transmitting HSDPA channels via MIMO or MISO transmitters. A transmitter may be configured to facilitate impairment correlation determinations by wireless communication receivers operating in MIMO/MISO environments, by signaling one or more values, e.g., data-to-pilot signal transmit power ratios and/or transmit antenna power distributions for the data and pilot signals.

摘要： Interference is estimated in an Orthogonal Frequency Division Multiplexing system by receiving at a wireless receiver pilot symbols and data symbols transmitted in time and frequency via resource blocks, detecting a first one of the data symbols transmitted to the wireless receiver via a time-frequency resource element of a first one of the resource blocks and identifying a second one of the resource blocks adjacent the first resource block having related interference parameters. The interference is estimated based on the pilot symbols transmitted via the first resource block and the pilot symbols transmitted via the second resource block.

摘要： Teachings herein provide reduced complexity channel state information (CSI) reporting for a successively decoded, precoded multi-antenna transmission. A wireless communication device reports CSI by forming, for each candidate transmission rank of the transmission, a sequence of codewords by iteratively adding codewords allowed for that rank to the sequence. At any given point in the sequence, the device adds the codeword expected to yield the highest individual information rate if decoded at that point in the sequence, considering the different rates possible under different precodings of the transmission. The device then computes, for each rank, a sum information rate across the codewords in the sequence formed for that rank, selects the rank having the highest sum information rate, and reports the selected rank along with the sequence formed for that rank. CSI reporting complexity is reduced because the device constrains its evaluation to only some of the possible decoding sequences.

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 plurality of timings are estimated for a received signal wherein the plurality of timings correspond to a plurality of transmitted signals. The received signal is then sampled in accordance with the plurality of timings, to produce a plurality of sample streams from the received signal. Channel estimates are produced for the plurality of transmitted signals and metrics are computed using the sample streams and the channel estimates. Information symbols corresponding to the transmitted signals are detected by using the metrics. Accordingly, by using multiple timings for a received signal, rather than using a common timing, the number of channel taps that are used may be reduced and the accuracy of symbol detection may be increased. The channel estimates may be produced by generating pulse-shape information and producing channel estimates for the multiple transmitted signals using the received signal and the pulse-shape information. Channel estimates may be produced that correspond to a plurality of symbol sequence hypotheses. Channel estimates may be updated using an error signal.
