Abstract: Systems, methods, and devices for grouping client devices based on sensor data in an assisted wireless communication system are provided. Sensor data may include device mobility, device type, and device application data usage, among other characteristics. An assisted wireless communication system may include client devices sending data to an access point. The clients may send conventional protocol data over a channel and, concurrently, send sensor data over an alternative channel. In some cases, client devices may exchange their protocol data, modify their own protocol data based on the exchanged data, and send the modified protocol data to the access point. This may allow the clients to adjust their grouping.

Abstract: A technique for dynamically adjusting power use of an input/output (I/O) interface of an electronic device is provided. The electronic device includes an input/output (I/O) interface that facilitates electronic communications with a receiving electronic device, at a particular transmission rate that is dynamically changeable by the electronic device. Transmission power and transmission rate adjustment circuitry determines whether a step-down in a transmission power used for signal transmission at the particular transmission rate is desirable. When desirable, the transmission power is dynamically adjusted down one step, such that less power is used by the I/O interface during the electronic communications.

Abstract: In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.

Abstract: Resource allocation logic in a user device can determine allocation of a shared resource among different communication modules supporting a number of different communication types (e.g., GNSS, cellular, Wi-Fi, and/or Bluetooth communications) in a context-dependent manner. For example, the logic can determine an operating context of the user device. Based on the operating context, the logic can assign a priority to each of the signal types. The shared resource can be allocated among the signal types based on the priority.

Abstract: A test system may be provided for performing wireless communications testing of electronic devices in a building. The test system may include a mobile cart that transports the device under test to test stations in the building. The test system may include a visible guide track having visible test station indicators. The mobile cart may include an optical sensor for detecting the visible guide track and the visible test station indicators. The mobile cart may transport the device under test to the test stations along the visible guide track. The mobile cart may include a rotating stage to which the device under test may be mounted. The rotating stage may be used to rotate the device under test while the device under test transmits test data to wireless communications equipment in the building during wireless communications testing of the device under test.

Abstract: Dynamic antenna switching based on weighted signal to noise ratio (SNR). A wireless device may include multiple antennas. SNR at each active antenna may be calculated. An antenna-specific weight may be applied to each antenna's SNR. The antenna-specific weights may further be radio specific and/or transmit or receive specific in some cases. Antenna selection (possibly just for a specific radio and/or for transmit or receive operations, depending on the specificity of the antenna weights), including potentially switching which antenna is used, may be based on the resulting weighted SNR values for each antenna. If the antenna-specific weights are radio specific and/or transmit or receive operation specific, the method may be performed multiple times with different antenna-specific weights to select antenna(s) for different radios and/or for other operations.

Abstract: A test system may include a master test station and slave test stations. The test stations may receive devices under test such as portable wireless electronic devices. Each test station may have adjustable antenna structures coupled to test equipment. The adjustable antenna structures may include antenna support structures on which test antennas are mounted and rail along which the antenna support structures and test antennas are moved by a pneumatic positioner. A rotatable platform may be provided in each test station to support the device under test in that test station. By making a series of over-the-air test measurements in the master test station while adjusting the antenna system and device positioning system, a satisfactory location for the active test antenna and device position may be identified. This configuration may then be used in performing single-point over-the-air tests in the slave test stations.
