  • Patent number: 10979853
    Abstract: The present disclosure describes how a master beacon having a known QUID can be used to capture beacons within its range and superimpose a systematic address scheme on those beacons. The superimposed address scheme can then be used as a proxy for the individual beacons when developing applications that make use of the beacons. A master beacon automatically detects each beacon in a plurality of beacons and, for a set of beacons in the plurality of beacons, automatically changes either the first profile identifier or the second profile identifier for each beacon in the set of beacons. The change is such that the first profile identifier or the second profile identifier is identical for each beacon in the set of beacons and is also associated with the master beacon.

  • Patent number: 10973022
    Abstract: Mitigating interference between access nodes in a wireless network includes determining interference caused to uplink signals received at a first access node by downlink signals transmitted from a second access node, and adjusting a guard period of a special subframe utilized by one or both of access nodes based on determining the interference, by switching special subframe formats to include a longer guard period. Overall interference is mitigated based on mutually-experienced propagation delay, and channel reciprocity. Adjustments are associated with known distances between access nodes.

  • Patent number: 10972235
    Abstract: Methods, systems, and devices for offloading traffic flows without service disruption are disclosed herein. User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized. The current PDN connection is established over a first PDN gateway (PGW). The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.

  • Patent number: 10959154
    Abstract: Nodes included in a hybrid network establish cellular links infrequently and at staggered intervals. When a node establishes a cellular link, other nodes can transmit and receive data to a back office using that cellular link. In addition, the node can receive a request from the back office across the cellular link indicating that another node should respond to an on-demand read request. The node can then signal the other node via a wireless mesh network to establish a cellular link in order to respond to the on-demand read request. An advantage of the disclosed approach is that a battery powered node can communicate as often as needed with the back office without frequently establishing a cellular link and without maintaining a continuously active cellular link.

  • Patent number: 10945282
    Abstract: The invention relates to a user equipment (UE) scheduled with uplink radio resources. At least one unlicensed cell is configured for communication between the UE and a base station (BS). The UE receives from the BS a first-stage uplink scheduling message. The UE determines whether the first-stage uplink scheduling message is valid, which comprises determining that it is valid in case one or more bits of one or more data fields in the first-stage uplink scheduling message are set to respectively predetermined values. The UE receives from the BS a second-stage uplink scheduling message related to the first-stage uplink scheduling message. The UE determines, when receiving the second-stage uplink scheduling message, that an uplink transmission is scheduled in case it determined that the first-stage uplink scheduling message is valid. The UE then performs, in case it determined that an uplink transmission is scheduled, an uplink transmission via the unlicensed cell.
