A method of measuring system integrity and robustness to link failure for use with a wireless signaling system is described. The measuring system can calculate the number of unique communication routs available for message transfer between an initiating device and a target device wherein unique routes are non-converging and defined by message source and signal strength data derived from a plurality of system devices.

A UE may receive, from a base station, a message requesting BSI. The UE may determine a number N of BSI reports to send to the base station, and each BSI report may indicate a beam index corresponding to a beam and a received power associated with the beam. The UE may send, to the base station, N BSI reports based on the message requesting BSI. The UE may receive, from the base station, a set of signals through a set of beams, and determine the received power for each signal of the set of signals received through each beam of the set of beams, each received power may be associated with a beam of the set of beams.

A UE may select a first beam for communication with a base station. The UE may attempt, through the selected first beam, at least one RACH procedure with the base station. The UE may determine that the at least one RACH procedure failed with the base station. The UE may send, after a successful RACH procedure with the base station, information indicating that the at least one RACH procedure failed. In an aspect, the UE may select a new beam for communication with the base station after the determination that the at least one RACH procedure failed, and at least a portion of the successful RACH procedure may be performed through the selected new beam.

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

Provided is a communication device (10) that is a node capable of communication with an external device, the communication device including a first transmission unit (120) that transmits power consumption data of the node and power consumption data acquired from another node to the external device, a second transmission unit (130) that transmits the power consumption data of the node to the other node, and a determination unit (140) that determines which of a process by the first transmission unit (120) and a process by the second transmission unit (130) is to be executed based on a predetermined condition.

A communication device, which structures a wireless mesh network of a tree structure, determines an initial path on the basis of a RANK value computed from a number of hops from a gateway of each communication device, from information of communication paths acquired from plural other communication devices, and determines a corrected path that is corrected from the initial path, on the basis of a consumed electric power estimated value of an own device that is communicated by the initial path.

A depth and distance-based single-path routing method, in which location information of nodes in network is gathered after initialization is completed, and a location table of whole-network nodes maintained by the sink node is generated. The update mechanism of the uplink Location frame is switched to a unicast triggering update mechanism to execute a depth and energy-based uplink routing algorithm. For a downlink control packet arriving at a specified ID, location information of a node is obtained through the location table to execute a distance and energy-based downlink routing policy. The distance and energy-based downlink routing policy for a downlink control packet arriving at a specified location and a downlink control packet arriving at the specified ID is executed, and a routing recovery algorithm is executed when an “open area” occurs.
