60results about How to "Improve user throughput" patented technology

When an access terminal is handed off, requested-data-rate information based on a data rate control signal from each access terminal, average throughput of each access terminal before handoff, and a handoff request count are obtained from a base transceiver subsystem. A throughput after handoff of each access terminal is estimated from a ratio of the data rate information of each access terminal to the number of connected access terminals, and an estimated throughput ratio representing the degree of change from the average throughput of each access terminal before handoff to the estimated throughput is calculated. If the estimated throughput ratio is lower than or equal to a given value, the corresponding access terminal is not handed off. If the estimated throughput ratio is higher than the given value, the access terminal having the highest estimated throughput among access terminals requesting handoff is handed off.

A transport installation with a continuous running aerial rope supports chairs and gondola cars coupled by detachable grips. The rope extends in a closed loop between two bull-wheels, with an up-line and a down-line. The installation presents loading / unloading terminals provided at least at the ends of said lines. One of the terminals comprises a transfer circuit connecting the up-line and the down-line, with a slowing-down section equipped with a slowing-down device, a speeding-up section equipped with a propelling device, connected by a run-through section with a low running speed equipped with a driving device of the vehicles. The transfer circuit comprises a continuous running speed regulating section equipped with a speed regulating means that is able to vary the time required by the cars and the chairs to pass through the speed regulating section, to impose a first predetermined running speed of the cars and a second predetermined running speed of the chairs.

The present invention relates to space-time or space-frequency coding in cellular systems. The same data is transmitted from different antennas with different coverage areas, corresponding to different cells. The different data streams have different parts of the space-time block codes applied. A mobile terminal can combine the different parts of the space-time block codes in different received signals. This provides better performance than the known techniques for single frequency networks. The invention can also be applied to antennas with different coverage areas from the same site, and different beams formed with antenna arrays.

An antenna multiplexing system and a method of a smart antenna and a Multiple-Input Multiple-Output antenna are provided, wherein the system includes a MIMO antenna array and a smart antenna array, the smart antenna array includes several groups of antenna array elements in which the distance between neighbor antenna array elements is less than or equal to one half of wavelength, and the smart antenna array comprises at least two groups of antenna array elements with the coherence sufficient for the requirement of the MIMO applications. The method includes: in accordance with the type of the data to be transmitted, determining a transmitting mode and processing the data to be transmitted accordingly, and in accordance with the transmitting mode, controlling the MIMO antenna array or smart antenna array, so as to transmitting the data to the mobile terminal. With the premise that the actual coverage of TD-SCDMA system should be further improved, the requirement of higher user throughout could be met, and the MIMO antenna system could satisfy the requirement of the future system evolution. Both of the applications of the MIMO and the smart antenna could be met with the use of the same antenna feeding system, and the adaptive switching of the MIMO and the smart antenna with respect to the user could be achieved.

A wireless communication terminal apparatus wherein even when a SC-FDMA signal is divided into a plurality of clusters and the plurality of clusters are then mapped to respective discontinuous frequency bands (when C-SC-FDMA is used), the improvement effect of system throughput can be maintained, while the user throughput can be improved. In the apparatus, a DFT unit (210) subjects a symbol sequence of time domain to a DFT process, thereby generating signals of frequency domain. A setting unit (211) divides the signals input from the DFT unit (210) into a plurality of clusters according to a cluster pattern that is in accordance with an MCS set, an encoding size, or the number of Ranks occurring during MIMO transmissions, which is indicated in those signals input, and then maps the plurality of clusters to the respective ones of a plurality of discontinuous frequency resources, thereby setting a constellation of the plurality of clusters in the frequency domain.
