    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: Embodiments relate to apparatus, systems, and methods for reception of calls on a mobile device that includes Wi-Fi and cellular radios. The mobile device may be configured to establish communication on a Wi-Fi network with a cellular carrier. The mobile device may further be configured to register a first IP address with an IMS server for the Wi-Fi network communication and register a second IP address with the IMS server for the cellular network communication (or register different ports of a single IP address with Wi-Fi and cellular). Upon occurrence of a mobile terminating call from the cellular carrier, the mobile device may receive an incoming call notification on one or both of the Wi-Fi network using the first IP address and the cellular network using the second IP address.

    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: A system and method for wireless device testing. The system includes a reverberation chamber (RC) and a downlink channel emulator. A wireless device is placed within the RC. Probe antennas are positioned within the RC. The downlink (DL) channel emulator couples to the probe antennas. The DL channel emulator is configured to: (a) receive downlink stimulus signals; and (b) generate downlink intermediate signals based on the downlink stimulus signals in order to emulate desired downlink channel characteristics. The probe antennas are configured to respectively transmit the downlink intermediate signals into the RC for reception by the wireless device. The system may also include an uplink channel emulator, which receives uplink transmit signals from the RC, and generates uplink terminal signals based on the uplink transmit signals in order to emulate desired uplink channel characteristics. The uplink transmit signals may be used to evaluated the performance of the wireless device.

    Abstract: An interface circuit in an electronic device (such as an access point) may utilize a configurable wake-up-frame format. During operation, the interface circuit may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies a proposed configurable wake-up-frame format. In response, the electronic device may determine the configurable wake-up-frame format to be used based at least in part on the proposed configurable wake-up-frame format. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response specifies the configurable wake-up-frame format selected for use. Note that the configurable wake-up-frame format may specify a payload length in a wake-up frame and/or one or more operations of at least one of the recipient electronic device or the electronic device after the wake-up frame is transmitted by the electronic 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: Wireless communication devices (UEs) may include multiple receive (RX) chains and associated antennas, and at least one transmit (TX) chain co-located with one of the RX chains. The UE may track instant fading of the antenna gain(s) during reception of packets from an associated access point (AP) device to which the UE intends to transmit packets. The UE may also track long term antenna gain(s), using any packets received at the multiple RX chains within the UE. At a switching occasion, a decision is made by the UE whether to switch antennas. If the instant fading detection is based on packets received no later than a specified time period prior to the switching occasion, then the UE may make the switching decision based on the results of the instant fading tracking. Otherwise, the UE may make the switching decision based on the results of the long term antenna gain tracking.
