  • Patent number: 10764016
    Abstract: Disclosed are a method and an apparatus for channel quality estimation in consideration of interference control and coordinated communication in a cellular system. A base station receives an SRS transmitted by a terminal to thus measure received power, and then configures, for the terminal, a CSI process which may measure SINRs for base stations having higher SRS received power. If the terminal feeds back, to the base station, channel quality information for the configured CSI process, the base station determines an SINR and a MCS to be applied to data transmission in consideration of a received CQI and a CoMP transmission scheme, and applies the determined SINR and MCS to thus transmit data.

  • Patent number: 10735261
    Abstract: Methods of upgrading a mesh network device reduce the amount of memory required on such devices. A network device may identify a neighbor network device in response to receiving a request to perform an upgrade, and send a message configured to cause the neighbor network device to function as a recovery node. The network device may then perform the upgrade without retaining a backup image in memory. If the neighbor network device determines that the upgrade failed based on messages not received from the mesh network device being upgraded, the neighbor network device may recover the network device being upgraded by providing a file corresponding to the upgrade. The neighbor network device may determine that the upgrade failed if no response is received to a challenge message or if no indication of success is received after a time expires.

  • Patent number: 10708172
    Abstract: A battery-powered node within a wireless mesh network performs energy-aware packet routing based on multiple factors. The battery powered node computes, for a given link to an adjacent node, the energy needed to transmit a packet to the adjacent node. The battery-powered node also determines the amount of battery energy remaining in the adjacent node. Based on these two factors, the battery powered node computes a link cost associated with the link to the adjacent node. The battery-powered node performs a similar computation for all adjacent nodes and then forwards packets via these adjacent nodes based on the associated link costs. The battery-powered node also maintains a table of routes through adjacent nodes, and reroutes packets through different adjacent nodes in response to link failures.
