摘要： An approach is provided for specifying channel state information in a multi-carrier communication system. A determination of either spectral locations of a first carrier and a second carrier, or correlation between the first carrier and the second carrier is made. A report format among a plurality of report formats is selected based on either the determined correlation or spectral locations. Each of the report formats specifies channel state information for the first carrier and the second carrier. The channel state information includes data rate information.

摘要： The present invention concerns methods for efficiently supporting Voice over Internet Protocol (VoIP) on the Forward Packet Data Channel (F-PDCH) in CDMA 2000 1xEV-DV systems. Active speech in VoIP is encoded using, for example enhanced variable rate codec (EVRC), which produces 171, 80 and 16 bits per 20 ms of speech for Rate 1, Rate 1/2 and Rate 1/8, respectively. However, about 60% of the time a user is inactive during a speech session, so an inordinate amount of system bandwidth is comprised of rate 1/8 VoIP packets. In one embodiment of the present invention the apparatus of the present invention identifies the Rate 1/8 voice frame packets and discards them. In another embodiment of the present invention, the apparatus of the present invention identifies the Rate 1/8 voice frame packets and selects some of them for further transmission. In both embodiments the efficiency of channel utilization is increased since the amount of channel band width used to communicate relatively little information, e.g., gaps of silence, is decreased.

摘要： An amusement simulation apparatus and method is disclosed. The simulation apparatus includes screen, projector, rotating platform carrying passenger, rotating shaft and aligned passenger seats round the machine room positioned on the platform and hanging by the suspending structure. When the platform is in upright position, passengers seating in the passenger seats face the screen positioned in front and view the image (2D or 3D) projected on the screen. The passengers are almost in the same vertical plane but in up and down relation. The blocking plate divided the passengers in different rows. The platform and the passenger seats can both pivot upon their shaft. Passenger seats in the left and right columns can rotate round the longitudinal yawing shaft to achieve better viewing effect. Pivoting movement of the passenger seat, combining the special effect of wind blasting, simulates the flying experience vividly. The simulation apparatus is suitable for use in an amusement park or theme park, providing tourists with interesting and life like flying experience.

摘要： A method and system for providing efficient transmission power control commands to a base station. In a third generation IS-95 CDMA network, for example, cdma2000, the forward pilot channel is used to estimate the received signal power level. In the presently preferred embodiment, a mobile station measures the received pilot channel power, on a forward link pilot channel. The loss experienced on the pilot channel is estimated as the difference between the pilot channel power transmitted at the base station and the pilot channel power received at the mobile station. The pilot power transmission power is typically fixed based upon the operating environment of the base station. The fixed pilot channel transmission power can be transmitted via a message from the base station. Based on the estimated channel loss, the received traffic power is calculated as the difference between the initial traffic channel transmission power, that is, the power when the mobile station is assigned a traffic channel, and the estimated loss added to any power control gain corrections that have occurred. The initial traffic channel transmission power can be a default value or can be assigned by the base station using signaling messages, e.g., a forward common control channel (or F-CCCH) message. Power control decisions are made based on the ratio of received traffic channel energy with an estimate of interference and noise on the channel. A “power control decision” is made by comparing the ratio with a predetermined threshold to determine if the power level should be raised or lowered.

摘要： Apparatus, and an associated method, for facilitating operation of a radio communication system that provides for multi rate data communications, such as a CDMA 2000 system that provides for 1xEV-DV communication services. A supplemental pilot, or control, signal generator embodied at a mobile station generates a supplemental pilot, or control, signal that is sent on a newly defined supplemental pilot, or control, channel. As the data rates of data communicated upon a reverse supplemental channel changes, corresponding changes are made to the power level of the reverse supplemental pilot, or control, signal.
