摘要:
The present invention provides a communication system, device and method of reverse link symbol timing synchronization of transmited signals to facilitate reverse link timing synchronization. A base unit transmits a forward link signal, receives a reverse link signal, and determines a timing offset for signals received on a reverse link timing synchronization channel, wherein the reverse link synchronization channel comprises a plurality of adjacent reverse link carrier frequencies that are utilized by a multicarrier subscriber unit to facilitate reverse link symbol timing synchronization. A plurality of multicarrier subscriber units receive a forward link signal and transmit a reverse link symbol timing synchronization burst on a reverse link timing synchronization channel wherein the reverse link timing synchronization channel comprises a plurality of adjacent reverse link carrier frequencies that are utilized by each subscriber unit, and adjusts a timing reference for transmitting signals to facilitate reverse link timing synchronization.
摘要:
The dual mode communication network comprises a first communication system having a frame structure and a first traffic channel protocol and a second communication system having the frame structure and a second traffic channel protocol. In the network, only one of the first and second traffic channel protocols supports forward error correction coding.
摘要:
A method is provided for dismissing or altering a user-configured alarm upon detection of the user's sleep state. The method includes associating an alarm device with the user's body by securing a wearable device to the user's wrist, placing the device in a pocket, integrating the device into the user's clothing such as a belt, or otherwise placing the device in contact with or adjacent to the user. The device includes one or more sensors for detecting physiological and/or environmental parameters such as heart, respiration, or pulse rate, body movements, eye movements, ambient light, and the like. If the user is asleep, the alarm is actuated in a typical manner. If the user is awake, the alarm is suppressed. If the user is neither asleep nor fully awake, the alarm is adjusted to provide an appropriate level of stimulation.
