摘要： A method and apparatus for communication between a wireless base station and a population of one or more terminals are provided, involving, in each of a plurality of iterations, transmitting a block of forward-link data from an array of multiple base station antennas to the terminal population. In each iteration, a forward-link power level is updated for each said terminal using a distributed algorithm and purely local information. Meanwhile, a set of beamforming coefficients based on channel state information (CSI) obtained from reverse-link pilot signals is periodically updated, and each data block is precoded with the most recently updated beamforming coefficients. Each data block is transmitted at the most recently updated forward-link power levels.

In implementations, a service transceiver station (STS) performs beamform precoding using channel state information (CSI) obtained from transmissions by the local terminals, and the STS performs power allocation using slow fading coefficients which are static over the service antenna positions and over a frequency range spanning at least some carriers used for downlink transmission.

摘要： A method and apparatus investigating a circumferential segment of a borehole with an array of elements, which in effect spatially samples the segment, is described whereby, with a single circumferentially oriented array of spaced-apart elements sufficient overlap can be synthesized so as to reduce artifacts attributable to the spatial sampling. Measurements derived from circumferentially successive elements are combined, such as by summing to establish a desired overlap. In the described embodiment to a single lateral array of small electrodes is used to inject survey currents into the borehole wall and each current is measured. Measurements derived from pairs of successive survey currents are then summed to provide the desired overlap.

摘要： Embodiments are described to mitigate network interference issues and to enable a significant increase in the throughput of wireless systems. In one method, pilot transmissions of a first and second group of wireless units are synchronized. Each wireless unit of the first group and each wireless unit of the second group use a different orthogonal pilot (than others in their group) from the same group of orthogonal pilots. Also, the pilot transmissions of the second group of wireless units are synchronized so as to be shifted in time from the pilot transmissions of the first group. In another method, data from neighboring cells and pilots from wireless units are received at a cell. Channel vectors for the wireless units are then estimated using the received data from neighboring cells, the received pilots from the wireless units and previously estimated channel vectors between the cell and the neighboring cells.
