Abstract: Methods and/or apparatus for reducing or avoiding (IDC) in-device coexistence problems in devices which support multiple communications protocols, e.g., WiFi and LTE, are described. In various embodiments a WiFi AP can request or require devices, e.g., STAs to report IDC information pertinent to the individual device. This is done by sending one or more trigger frames, e.g., as part of a multicast or unicast operation. Alternatively, devices can voluntarily report IDC information. The AP, e.g., WiFi AP, takes the IDC information it receives, e.g., from multiple devices, e.g., STAs, into account when scheduling UL resources to be used by the wireless devices. By taking into consideration the IDC information provided by STAs, IDC conflicts can be avoid even though a WiFi AP is scheduling resources for WiFi communication in devices which are also using resources for another communications standard, e.g., LTE, over which the AP does not have control.

Abstract: Channel information is accessed that identifies a plurality of channels, and for each channel a multicast address to which packets carrying channel content are addressed. Multicast data rate information is obtained from a plurality of routers that identifies, for each respective router, a real-time data rate of data addressed to a multicast address being routed by the respective router. It is determined, based on the multicast data rate information, that an output channel data rate of a first channel of the plurality of channels is lower than an expected output channel data rate that corresponds to the first channel. Information indicating that the first channel has an output channel data rate that is less than the expected output channel data rate is presented on a display device.

Abstract: Methods and apparatus for determining losses due to obstructions in a wireless communications system are described. Pairs of measurements points, one of each side of an obstruction are selected, and wireless device reported received signal energy measurements corresponding to the pair of selected locations are used to determine a path loss through the obstruction. In some embodiments, the pair of measurements points are selected based on one or more of: wireless device orientation at the time of measurement, application in use at the time of measurement, time between measurements, or location between measurements. In one example, a first selected location in the pair corresponds to an outdoor location with a unobstructed line of sight view to the base station, while the second selected location corresponds to an indoor location.

Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for enabling dynamic configuration of CBSD devices with CBRS spectrum grants defined/sized using enhanced SAS channel assignment capabilities supporting low bandwidth channels/applications (e.g., IoT services) in the shared spectrum while minimizing spectrum wastage. Existing CBSD-SAS call flow message exchange and registration data specifications are modified in accordance with various embodiments to provide support for radio types having spectrum requirements less than the nominal minimum channel size.

Abstract: Establish a secure connection from a device to a server by, at the device: sending a shared secret request (SSRq) and an obfuscated secret value of the device to the server, wherein the SSRq is encrypted by a symmetric rolling key known to the device and to a trusted authority but not known to the server and the SSRq incorporates a symmetric key for decrypting the device's obfuscated secret value; receiving a shared secret response (SSRs) and an obfuscated secret value of the server, wherein the device's symmetric rolling key encrypts the SSRs and the SSRs incorporates a symmetric server obfuscation key for decrypting the server's obfuscated secret value; calculating a shared secret by hashing a concatenation of the device's secret value and the server's secret value; generating a symmetric session key based on the shared secret; and establishing the secure connection using the symmetric session key.

Abstract: A first dual SIM user equipment (UE) has a first wireless connection to first Citizens Broadband radio Services Devices (CBSD) of a first network and a second wireless connection to a second CBSD of a second network. Different encryption and different frequency hopping patterns are used with regard to communicating the same voice packet information over the first and second wireless connections. The same voice information is attempted to be redundantly communicated over the two connections, e.g. concurrently or with a slight delay with regard to the two connections. The CBRS communications are typically less reliable than cellular licensed spectrum communications, and a particular encrypted voice packet may, and sometimes is lost; however, the redundancy is used to compensate for expected losses. Successfully recovered encrypted voice packets are sent from the CBSDs to a packet synchronizer which performs decryption and combines the recovered packets into a single packet stream.

Abstract: A system includes a primary playback system and a secondary playback system. The primary playback system plays back selected content. The secondary playback system plays back supplemental media associated with the content played back on the primary playback system. A media playback function (such as associated with the secondary playback system) monitors playback of the content on the primary playback system. For example, a first processing thread of the media playback function initially synchronizes playback of supplemental media on the secondary playback system with respect to playback of the content on the primary playback system. Based on further monitoring of playing back the content on the secondary playback system, a second processing thread of the media playback function verifies synchronization (and, when needed, initiates re-synchronization) of playback of the supplemental media on the secondary playback system with respect to playback of the content on the primary playback system.

Abstract: A wireless network environment includes communication management hardware such as disposed in customer premises equipment. The communication management hardware detects a request communication from a mobile communication device, the request communication transmitted from the mobile communication device to a wireless base station. In response to detecting the request communication, the customer premises equipment monitors for reply communication from the wireless base station. The communication management hardware detects failure of the wireless base station to respond to the request communication. In response to detecting the failure, the communication management hardware operates in a relay mode to provide the mobile communication device connectivity with the wireless base station.

Abstract: A wireless network environment includes a communication management resource operative to manage wireless connectivity provided by multiple different wireless networks, each of which supports a different wireless communication protocol to provide wireless access to communication devices in a network environment. The communication management resource monitors a performance of the multiple wireless networks. In response to detecting an inability of a first wireless network of the multiple wireless networks to provide wireless coverage in a geographical region, the configuration management resource adjusts operation of a second wireless network to provide expanded wireless coverage in the geographical region.

Abstract: A device management resource detects an anomaly event associated with a first communication device based on analysis of first feedback from multiple network entities supporting conveyance of communications associated with the first communication device. The device management resource selects an operational state of the first communication device based on the detected anomaly event. The device management resource then notifies each of the network entities of the selected operational state of the first communication device. Each of the network entities collects and forwards different feedback data associated with the first communication device depending on the selected operational state of the first communication device.
