    摘要： A method and system for minimizing the control overhead in a multi-carrier wireless communication network that utilizes a time-frequency resource is disclosed. In some embodiments, one or more zones in the time-frequency resource are designated for particular applications, such as a zone dedicated for voice-over-IP (VoIP) applications. By grouping applications of a similar type together within a zone, a reduction in the number of bits necessary for mapping a packet stream to a portion of the time-frequency resource can be achieved. In some embodiments, modular coding schemes associated with the packet streams may be selected that further reduce the amount of necessary control information. In some embodiments, packets may be classified for transmission in accordance with application type, QoS parameters, and other properties. In some embodiments, improved control messages may be constructed to facilitate the control process and minimize associated overhead.

    摘要： Methods and systems for contingency communication are disclosed. In one embodiment, a method for providing emergency services may be performed by a base station operating in a communication system. In an embodiment, the method for providing emergency services includes transmitting a beacon signal to indicate an emergency status to enable portable devices to operate in a stress mode. A distress signal may be transmitted by a mobile device in response to the beacon signal to the base station, wherein the distress signal carries information at least comprising user identity associated with the mobile device, geolocation of the mobile device, or biometrics of a user of the mobile device.
