Abstract: A network system customizes communications and communication channels for delivery to candidate providers registering with the network system. Candidate providers progress through steps of a network registration process by providing input data at the various steps. The network system provides communications to request the input data and facilitate the candidate providers' progress. The network system can use a machine learning model to predict particular types of communications and communication channels (e.g., online messages, phone calls, physical mail, etc.) that are likely to be well-received by candidate providers. Thus, the network system is able to increase the expected number of candidate providers that successfully register to provide services to other users of the network system.

Abstract: A transmit beamforming gain and a receive beamforming gain may be used when adjusting an uplink transmit power. For example, a user equipment (UE) may receive downlink communications from a base station on a receive beam having a beamforming gain that is different from a beamforming gain for an uplink transmit beam. The UE may adjust an uplink transmit power (e.g., for transmitting a random access channel (RACH)) based on a difference in the beamforming gains. For example, a parameter representing the difference in the beamforming gains, in addition to a maximum allowed transmit power, a target preamble received power, and an estimated path loss, may be used when determining an adjusted uplink transmit power for a RACH transmission. The adjustment may result in a higher or lower transmit power depending on the difference in the receive beamforming gain and the transmit beamforming gain.

Abstract: A wireless communication system and method that includes configurable Carrier Aggregation (CA) and/or Multiple-input Multiple-output (MIMO) operational modes. In CA, multiple carriers (i.e., channel bundling) are aggregated and jointly used for transmission to/from a single terminal. Downlink inter-band carrier aggregation increases the downlink data rates by routing two signals, received in different frequency bands, simultaneously to two active receivers in the RF transceiver. MIMO utilizes two additional receivers as diversity paths and the frequency generation can be shared between main and diversity path for each carriers.

Abstract: A central management system polls a lighting node in a mesh lighting network, sending a command message for the node to measure a link quality indication (LQI) of the received command message. The node returns a status message, including in its payload the measured LQI. The management system computes from the node's status messages, a statistical characterization of the link quality of the node and compares it with a threshold quality value. If the comparison indicates sufficient degradation in link quality, the management system automatically transmits a disconnect command to the node. In response, the node disconnects and enters a discovery mode to find a better quality link to rejoin the network. In example embodiments, the lighting node may also report its illumination and operational status in the payload of the status message, along with the LQI, enabling the management system to determine whether illumination by the node is failing.

In some implementations the requesting node transmits the discovery data received from the group communication service to other communication nodes using low-energy transmissions. In some implementations the group communication service transmits the discovery data to local communication nodes located within a proximity range of the requesting node.
