摘要： A receiver, or base station, may calculate the signal quality improvement based on a change in a diversity control parameter, for example, a phase difference or a power ratio among two or more antennas, by comparing a received signal power level to an expected power level, assuming no change in fading characteristics at the previous timeslot. This method may increase the amount of information communicated between the base station and the mobile unit, and may reduce feedback response time and/or provide for more efficient feedback for transmit diversity systems.

摘要： Communicating a signal includes establishing a quality indicator at a first communication device that has antenna elements. The quality indicator indicates the quality of communication links between the first communication device and a second communication device. A modification describing an adjustment of a modulation feature is determined according to the quality indicator. The availability of the quality indicator is established. Modulation of a subset of signals in accordance with the determined modification is initiated in response to establishing the availability of the quality indicator. The antenna elements send the signals to yield a transmitted signal.

摘要： A signal is modified according to a current diversity parameter adjustment, and is transmitted from a modifying communication device to a feedback communication device. A feedback signal reflecting feedback information describing the signal as received by the feedback communication device is received. The feedback signal comprises frames, and a frame comprises slots, where a slot has a slot power value. The frame timing of the frames is established from the slot power values. The signal is modified according to a next diversity parameter adjustment in accordance with the frame timing.

摘要： A system and method for using a group of pilot signals to enhance a data signal within an orthogonal frequency division multiplexing (OFDM) multiple-access scheme is described. The OFDM multiple-access scheme has multiple OFDM transmitters using at least overlapping frequency spectrums, during at least overlapping time period, in at least overlapping geographic areas. A set of data signals and a set of pilot signals are received on antenna elements. Each group of data signals from the set of data signals is uniquely associated with a group of pilot signals from the set of pilot signals. Each pilot signal from the set of pilot signals is uniquely associated with its own code from a set of codes. Each code from the set of codes is uniquely associated with an OFDM transmitter from the multiple OFDM transmitters. A group of pilot signals from the set of pilot signals is identified based on its uniquely associated code. A weight value associated with each antenna element from a set of antenna elements is adjusted so that a level of correlation between the group of pilot signals and the code uniquely associated with the group of pilot signals is enhanced while a level of correlation between the remaining groups of pilot signals from the set of pilot signals and the codes uniquely associated with those remaining group of pilot signals are suppressed.

摘要： Modifying a signal includes facilitating transmission of the signal from a modifying communication device to a feedback communication device. Power indicators reflecting the power of the signal as received by the feedback communication device are received. Previous power indicators reflect the power of the signal adjusted according to a previous modification, and current power indicators reflect the power of the signal adjusted according to a current modification. A previous power descriptor value is estimated from the previous power indicators, and a current power descriptor value is estimated from the current power indicators. A modification increment is determined in accordance with the previous power descriptor value and the current power descriptor value. A next modification is calculated from the current modification and the modification increment, and a phase and an amplitude of the signal are adjusted in accordance with the next modification.

摘要： A system and method for expanding high inbound message traffic in a two-way pager network. The network includes a central base station which receives inbound messages from a plurality of subscriber units via a plurality of receiver base stations, and wherein a central base station controller is adapted for receiving only one inbound message from a subscriber during each inbound transmission time slot. Inbound message capacity is expanded by providing a message management system between the receivers and the central base station controller. Subscribers are selectively grouped into a multicast group for simultaneously transmitting messages to the message management system, the simultaneously transmitted messages making up a multicast message group. The message management system receives the multicast message group, directs exactly one selected message of the multicast message group to the central base station controller, and diverts the remaining messages to a multicast processor.

摘要： Method and apparatus for resolving conflicts between the transmission or reception of disparate information over disparate beams transmitted or received by more than one base station. Simultaneous transmissions or receptions from a multiplicity of base stations carrying disparate messages on the same frequency are allowed. In certain pager-related embodiments, method and apparatus are provided for determining which subscriber units are accessible by any given beam, for determining the interference among beams, and/or for allocating transmission times for messages for various beams to support multiple simultaneous disparate transmissions or receptions, while ensuring that all subscriber units requiring service will get good quality of service in terms of signal to noise ratio, signal to interference ratio, and latency.
