    Abstract: Methods and devices are provided for processing a received communication signal by a UE using an analog complex filter and using a single analog-to-digital converter (ADC). A control channel of the communication signal may be decoded to determine the frequency range in which a payload channel is located. The UE may then demodulate only the frequency range containing the payload channel. A complex representation of the received payload channel may be provided to the analog complex filter, with the payload channel shifted to a non-zero frequency IF. The analog complex filter may attenuate any portion of the complex representation that falls near −IF. The UE may then convert only one component path of the filtered complex representation to a digital signal. A complex representation of the digital signal may then be generated, with the payload channel shifted to DC.

    Abstract: Mechanisms for operating a wireless user equipment device, to determine the state of data scheduling activity. Such activity state (and other information such as measurements of signal interference and/or channel condition) may be used to dynamically control the selection of a high-power high-performance receiver vs. a low-power basic receiver. A first mechanism involves transitioning to a high activity state and starting a timer upon each occurrence of scheduled subframe. A transition to the low activity state occurs whenever the timer expires. A second mechanism involves filtering a sequence of binary-valued indicators corresponding respectively to a sequence of time intervals. Each indicator indicates whether a subframe is scheduled during the corresponding time interval. The filter output is compared to a threshold to determine high/low activity state. The temporal width of the filter impulse response may be increased to support fast initial response without harming the accuracy of activity-state determination in the steady state.

    Abstract: Disclosed herein are system, method, and computer program product embodiments for providing an efficient way to assign resource blocks to user receiver devices in a wireless communications protocol. For example, the method can receive a frame for a wireless communications protocol. The method can also extract a unique value from a tone mapping field in a preamble of the frame. The method can also look up a resource block allocation for a portion of the tone space in a lookup table using the unique value. Further, the method can extract an assignment field from the preamble based on the determined resource block allocation. The method can also determine an assigned resource block number based on the assignment field. The method can also assign a resource block corresponding to the assigned resource block number to a user receiver device.

    Abstract: This disclosure relates to techniques for transmitting and receiving control information in the common search space on an enhanced physical downlink control channel (EPDCCH). According to some embodiments, a cellular base station may allocate some resource blocks of a subframe as the EPDCCH. The cellular base station may provide control information on a common search space in the EPDCCH for wireless user equipment (UE) devices in the cell provided by the cellular base station during a subframe. A UE device may monitor the EPDCCH to determine whether any indication on the common search space decodable by the UE device is contained in the EPDCCH, and may decode such information if present.

    Abstract: A host device may include a first wireless communication circuit, a second wireless communication circuit including a proxy router, and a host processor communicatively coupled to the wireless communication circuits. The host device may receive, via the second wireless communication circuit, an advertisement message from a client device. The advertisement message may include a request for communication of data with a network. The host device may determine at least one of a communication policy preference of the host device and a network connection property of the host device. The proxy router may select the first or the second wireless communication circuit for use by the host device to communicate the data with the network. The host device may provide, via the second wireless communication circuit, a connection request to the client device, and then transfer, using the selected wireless communication circuit, the data between the client device and the network.
