Abstract: A single chip mobile wireless device capable of receiving and transmitting over one wireless network at a time maintains registration on two wireless communication networks that each use different communication protocols in parallel. Periodically, the mobile wireless device tunes one or more receivers from a first wireless network to a second wireless network in order to listen for paging messages addressed to the mobile wireless device from the second wireless network. The first wireless network suspends allocation of radio resources to the mobile wireless device based on receipt of a suspension message from the mobile wireless device, or based on knowledge of a paging cycle for mobile wireless device in the second wireless network, or based on detection of an out of synchronization condition with the mobile wireless device.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a wake-up beacon to a recipient electronic device. During operation, the interface circuit may provide a wake-up beacon associated with a predefined sub-channel in one or more channels in a band of frequencies, where the wake-up beacon is for a wake-up radio in the recipient electronic device. Moreover, the wake-up beacon may be provided within an associated time interval, such as a keep-alive interval of the electronic device. In some embodiments, the wake-up beacon includes a field with channel information that specifies one or more second channels used by a main radio in the recipient electronic device. Alternatively or additionally, the wake-up beacon may include a field with service information that specifies one or more types of services and/or a field with information specifying a transmit power of the interface circuit.

Abstract: A method of modulating transmission power to facilitate in-device coexistence between wireless communication technologies is provided. The method can include determining a scheduled time period during which data is received by a device via a first wireless communication technology. The method can further include reducing a transmission power of a transmission from the device via a second wireless communication technology to a threshold level prior to the scheduled time period and controlling the transmission power so that the transmission power does not exceed the threshold level during the scheduled time period. The method can additionally include, subsequent to the time period, increasing the transmission power to a level exceeding the threshold level.

Abstract: Methods and apparatus for adaptively adjusting receiver operation for e.g., power optimization. In one embodiment, operation during diversity operation is adaptively adjusted. Diversity techniques consume significantly more power than non-diversity operation. However, the performance gain from receiver diversity is not always predictable. Consequently, in one embodiment, a device evaluates the overall performance gain contributed by diversity operation and, where the performance gain is insignificant or inadequate, the device disables diversity operation. In one implementation, the device can operate in a static single antenna mode, a dynamic single antenna mode and a dynamic multiple antenna mode.

Abstract: A device and method generates a hopping scheme for mobile stations of a wireless network. The method includes receiving a number of channels N of the wireless network. The method includes generating a shuffling matrix as a function of the number of channels N, each row of the shuffling matrix being indicative of a respective one of the mobile stations, each column of the shuffling matrix being indicative of a respective broadcast time of a discovery signal in a hopping scheme. The method includes generating the hopping scheme for the mobile stations in the channels as a function of the shuffling matrix. The hopping scheme maximizes an interval between two consecutive broadcast times that any two of the mobile stations are assigned to transmit discovery signals on adjacent channels.

Abstract: Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected “tune-away” period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

In one implementation, the mobile device includes an LTE-enabled UE, and the intelligent diversity management includes selectively disabling receive diversity (RxD) in that device upon meeting a plurality of criteria including (i) a capacity criterion, and (ii) a connectivity criterion. In one variant, the capacity criterion includes ensuring that an achievable data rate associated with a single Rx (receive) chain is comparable to that with RxD.

Abstract: A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.
