    摘要： Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station can allocate persistent resources to a client station, and can associate the client station or persistent resource allocation with a particular shared NACK channel. The base station can monitor the NACK channel for a NACK indicating a map error. The base station can also monitor the resource allocation to implicitly determine a map error. The base station can resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation can monitor persistent resource allocation information elements in map messages and can indicate failure to receive a persistent resource allocation information element in a NACK message on a preassigned share NACK channel.

    摘要： Methods and devices for operating a wireless communication device that can communicate with at least two different wireless networks using a single radio frequency modem are described. The communication device attaches to a first wireless network through the radio frequency (RF) modem, and then detaches from the first wireless network at a predetermined time before a start time of a selected event on a second wireless network. The device attaches to the second wireless network using the same RF modem before the start time of the selected event and collects at least a portion of event data associated with the selected event. After collecting at least a portion of event data, the device detaches from the second wireless network and re-attaches to the first wireless network.

    摘要： On embodiment of the system and method provides asymmetric adaptive modulation which allows uplink and downlink subframes (304, 302, respectively) of data to be transmitted between a base station (102) and a CPE (104) with different modulation schemes, thus increasing the efficiency of downlink transmissions while maintaining the stability of uplink transmissions. In systems with multiple CPEs, each CPE (104) and base station (102) pair can independently select their uplink and downlink modulation techniques. The system and method are also adaptive in that they adjust the modulation schemes based on, for example, signal to noise ratio measurements or bit error rate measurements.
