摘要： Apparatus and methods are disclosed for control of an idle mode in a wireless device. In particular, the idle mode duty cycle of a preamble transmission by an access point (AP), as an example, is variably or adaptively set in response to determined conditions of the wireless neighborhood. The conditions determined include the whether or not other wireless devices are present in the vicinity of sensing wireless device, as well as the state of those devices present, such as whether they are in an idle mode or an active mode.

摘要： Apparatus and methods for controlling sleep mode in a wireless device are disclosed. The sleep mode is controlled using low power detection of RF beacon signals of known frequencies to reduce power consumption of the wireless device during sleep modes. Detection is achieved by using passive or low power elements in a receive chain that filters received signals allowing beacon signals of particular frequencies to pass, which are accumulated with passive or low power circuit elements requiring no external power source. The accumulated energy is compared to a threshold to determine the presence of the beacon with sleep circuitry. When the beacon is detected, the full RF receiver is triggered to wake up. Use of low power elements and passive elements, affords a beneficial increase in power savings for the wireless device, which is particularly helpful in wireless access points or relay stations that have an alternative power sourcing such as battery or solar power.

摘要： A method and apparatus are presented for compensating drifts in access terminals occurring during a sleep time. The method includes determining whether a sleep time exceeds a threshold, buffering time domain samples containing acquisition pilots and a paging channel, powering down RF circuitry in the access terminal after buffering samples, processing the samples to compensate for drift, and determining whether the access terminal was paged based upon the processed samples. The apparatus includes a digital front end, an FFT engine coupled to the digital front end, a symbol buffer coupled to the FFT engine, a processor coupled to the digital front end, FFT engine, and symbol buffer, and a memory coupled to the processor, the memory further comprising instructions for executing the method.

摘要： A coexistence manager may manage potential resource conflicts between radios, in particular between a Long Term Evolution (LTE) radio and between a Bluetooth radio. Coexistence manager decision units may be designed synchronously to occur at preset times, or asynchronously as needed by the respective radios. The decision units may be structured to reduce latency. The decision units may be configured specifically for the Long Term Evolution radio and Bluetooth radios.
