When the mobile computing device connects to the mesh network, the location of the mobile computing device may be determined by determining which mesh network nodes the mobile computing device is connected to, triangulating the position of the mobile computing device based on signal direction via directional antennas arranged on the mesh network nodes, and/or measuring signal strength of the mobile computing device at the mesh network nodes.

Abstract: Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.

Abstract: A method for a wireless communications system is disclosed. In one example, a user equipment (UE) device (e.g. a mobile phone) provides a UE beam sweeping number to a network node. Based on the UE beam sweeping number, the network node provides configuration information or allocates a resource to the UE device. The UE device can use the configuration information or the resource for measurement. The beam sweeping number refers to the number of time intervals that the UE device would need to generate multiple sets of UE beams, one set per time interval, that would cover all possible directions in which the UE device sends and/or receives transmissions, in a manner that resembles a sweeping of UE beams.

Abstract: A method for congestion control in a data communication protocol employing acknowledged communication may include measuring a flight size. A transmission rate may be measured. A trend of the flight size may be determined. A trend of the transmission rate may be determined, and the trend may be derived from a transmission rate gradient calculation, in which either the transmission rate measurements or the transmission rate gradient calculations or both may be filtered to reduce their temporal variability. Whether there is a congestion may be detected according to the determined trend of the transmission rate and the trend of the flight size. Upon detection of the congestion, a change may be made from a current congestion control state to a new congestion control state. Data may be transmitted while respecting a maximum amount of unacknowledged data which the transmitting node may transmit. An apparatus is also disclosed.

Abstract: A status value used to identify a topology status of service nodes at a specified time is preconfigured for a packet in a packet flow, so that when a service node in a next hop is selected for the packet, selection is performed not based on a topology status of current actual service nodes in the next hop, but based on the topology status, which is identified by the status value, of the service nodes at the specified time. As long as status values carried in packets in a same packet flow are the same, even if a topology status of service nodes changes, a same service node can still be selected for the packets in the same packet flow, thereby avoiding a problem of diversion of the packets in the same packet flow.

Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.

In an embodiment, a communications interface is configured to receive a first packet paging message sent by a core network node; a processor determines, according to the first packet paging message received by using the communications interface, that a terminal is an M2M terminal; and a transmitter sends a coverage-enhanced second packet paging message to the terminal.

Abstract: A connection may be established between a base station and a user equipment (UE) using a radio frequency shared by multiple network operating entities. Resources (e.g., a frame) may be divided into exclusive, prioritized, and opportunistic sub-intervals for a given network operating entity coexisting within the shared radio frequency spectrum. Additionally, a set of low latency sub-intervals (e.g., reserved resources) may be designated for use by the network operating entity for mission critical (MiCr) and/or autonomous uplink transmissions. The network operating entity may indicate timing information for low latency sub-intervals during a sub-interval for exclusive use by the network operating entity. The UE may then transmit MiCr and/or autonomous uplink messages using the low latency intervals without performing a medium sensing procedure. In some cases, the sub-intervals for MiCr and autonomous uplink transmissions may be for exclusive use by the network operating entity.
