Inventor: WEI YONGBIN
IPC: H04B7/005
Filed: 2004-02-18
Abstract: Systems and methods for controlling power in a wireless communication system having multiple reverse-link channels. One embodiment comprises adjusting power levels of a first set of channels and a corresponding pilot channel while maintaining a set traffic-to-pilot (T/P) ratio between them, and adjusting T/P ratios for one or more remaining channels independently of the power level of the pilot channel. A base station determines whether frames received on the first set of channels contain errors and sends messages to a mobile station to increment or decrement the power levels, respectively, if the frames do or do not contain errors. T/P ratios of the additional channels are adjusted by determining whether frames received on the additional channels contain errors, incrementing or decrementing the T/P ratios appropriately, and transmitting the T/P ratios to the mobile station, which controls the transmission parameters for the respective channels in accordance with the received T/P ratios.

Abstract: A handheld device includes a host database having first and second API  associated therewith, a client database and a notification handler. The notification handler sends a request for notification of a change in the host database to the first API and receives the notification of the change in the host database after the change has occurred in the host database. The notification handler then requests the contents of the host database from the second API and requests contents from the client database, which are compared.  The notification handler then sends a command to update the client database based upon the change in the host database such that changes made in the host database may be continuously synchronized with the user's desktop computer via a wireless communication network.
