  • Patent number: 11374665
    Abstract: Multiple Reference Signal Received Power (RSRP) measurements are obtained at a sampling location for non-millimeter wave radio signals of multiple non-millimeter wave frequencies originating from an antenna site of a base station. A line-of-sight (LOS) distance, an azimuth angle, and an elevation angle between the antenna site and the sampling location are computed. A corresponding Effective Isotropic Radiated Power (EIRP) measurement at the sampling location for each non-millimeter wave radio signal of the non-millimeter wave radio signals is calculated based on a radio transmission power and an antenna gain factor associated with each non-millimeter wave radio signal. A corresponding path loss exponent at the sampling location for each non-millimeter wave radio signal is then computed based at least on a difference between a corresponding RSRP measurement and the corresponding EIRP measurement, the LOS distance, and a wavelength of a corresponding non-millimeter wave frequency.

  • Patent number: 11375432
    Abstract: In a 5G network, an integrated access and backhaul (IAB) network can experience radio link failures or radio blockage conditions in mmWave frequency bands. Local IAB nodes that experience such conditions can make route changes in response to such situations to prevent packet loss or significant packet delay. Thus, in an IAB network, local IAB nodes can also utilize a routing function that monitors local conditions of IAB links to determine whether a change in route is required or not. Additionally, the local IAB nodes can receive external routing updates that can preempt a local IAB node routing function. Consequently, the IAB node can consider local routing preferences and external routing preferences prior to updating a routing table of the IAB node.

  • Patent number: 11368393
    Abstract: Disclosed embodiments relate to a Hierarchical Do-Dag based RPL (H-DOC) network configuration where the network address of each node corresponds to its location within the hierarchical network. Network addresses are initialized hierarchically. Candidate patent nodes signal availability. Candidate child nodes respond to a selected candidate parent node with a temporary address. The selected candidate parent node acknowledges selection and communicates a hierarchical address for the child node in a transmission to the temporary address. The child node changes its address to the hierarchical address from the parent node. When a node switches parent nodes, it signals the old parent node to deallocate it as a child node, and then signals a selected candidate parent node with a temporary address.

  • Patent number: 11356950
    Abstract: A system for a tag includes a network controller that, when it has information to send to a tag, is configured to communicate with the tag's neighbors, such as anchors that may be used for communication between the tag and the network controller. In this regard, the network controller may instruct the tag's neighbors to stun the tag upon hearing from the tag. Thus, when the tag transitions out of a sleep state and transmits a status message or other type of message to the network controller or other resource of the network, at least one neighbor of the tag hears the message and, in response, stuns the tag so that it remains awake for a longer period of time, thereby giving the network controller sufficient time to send control information or other information to the tag. Since the neighbors are responsible for stunning the tag, the amount of time required to stun the tag after it awakens from the sleep state is decreased.
