A system for managing power on distributed devices may include a first device having a master logic and a second device having a slave logic. The master logic may enable the first device to communicate with multiple devices having the slave logic on one or more channels. The slave logic may enable the second device having the slave logic to communicate with the first device and to communicate with a third device having the slave logic. The slave logic may enable the multiple devices having the slave logic to manage operations of the distributed devices.

A method of radio communication of a slave device with a master device, the method comprising steps of: receiving (202) by the slave device of a connection request sent by the master device comprising first communication parameters for communicating with the master device, the communication parameters being indicative of a sequence of frequency channels to be used during successive periods to communicate with the master device, during one of the periods, implementing by the slave device of a processing capable of causing the master device to send a connection update comprising second parameters for communicating with the master device to be used in place of the first communication parameters, the processing comprising an action (210) on one of the frequency channels capable of causing the master device to detect a degradation in communication quality on the frequency channel.

Techniques that provide link auto-negotiation between a radio equipment controller (REC) and a radio equipment (RE) are described herein. In one embodiment, a method includes performing, by a proxy master, a Common Public Radio Interface (CPRI) Layer 1 (L1) link auto-negotiation with a RE to achieve a L1 synchronization between the proxy master and the RE at a link bit rate; communicating the link bit rate from the proxy master to a proxy slave; performing, by the proxy slave, a CPRI L1 link auto-negotiation with a REC to determine whether a L1 synchronization between the proxy slave and the REC is achieved, wherein if the L1 synchronization is achieved, the link bit rate is a common matching link bit rate achieved; and upon the common matching link bit rate being achieved, establishing a CPRI link between the REC and the RE using the common matching link bit rate.

Systems and methods can support identifying pairings and channel parameters in short-range wireless communications such as bluetooth low energy interfaces. Radio frequency sensors may be positioned within an electromagnetic environment where a master wireless device and a slave wireless device share short-range wireless communications. Signals transmitted between the master wireless device and the slave wireless device can be received by the radio frequency sensors. Inter-arrival times for packets within the received signals may be identified. Statistics of the inter-arrival times can be analyzed to identify connection intervals between the master wireless device and the slave wireless device as well as back-to-back interval exchanged within the connection intervals. Packet header contents may be used to reconcile the estimated timing parameters and time slots. Pairings between the master wireless device and the slave wireless device may be identified and tracked along with communication channel parameters.

Exemplary embodiments include methods and/or procedures for handling messages from one or more data-plane nodes (DPNs) to a plurality of controller nodes configured in a cluster, comprising: receiving a message from a DPN; tagging the message with an incarnation identifier (IID) associated with the DPN; and performing HD handling of the tagged message, which includes comparing a value of the IID of the tagged message with a value of a global IID associated with the DPN, discarding the tagged message if the value of the IID of the tagged message is less than the value of the global IID, and processing the tagged message if the value of the IID of the tagged message is not less than the value of the global IID. Exemplary embodiments also include controller nodes, controller clusters, and computer-readable media embodying operations of the exemplary methods and/or procedures.

A method for communicating data between Bluetooth Low Energy (BLE) devices in a network (100) including multiple nodes (200, 202). The method includes starting a scan mode at a first node (200) having data to send; and determining whether data to send has been transmitted to the first node from an upstream node or a downstream node. If the data to send was received from a downstream node, the first node begins a scan mode. If the data to send was received from an upstream node, the first node begins an ADV event.

Certain aspects of the present disclosure relate to assisting communications with low data payloads with relay nodes. An example method generally includes forming a first cluster with a first wireless node and one or more second wireless nodes, wherein each of the second wireless nodes has a low data rate demand relative to a system bandwidth. The method also includes determining to serve as a relay node for the first cluster, generating a first set of packets for uplink transmission to a base station, receiving a second set of packets from the one or more second wireless nodes, combining the first set of packets and the second set of packets into an uplink payload based on the determination, and transmitting, to the base station, the uplink payload based on the determination.

A network includes at least one node to communicate with at least one other node via a wireless network protocol. The node includes a network configuration module to periodically switch a current node function of the node between an intermediate node function and a leaf node function. The switch of the current node function enables automatic reconfiguration of the wireless network based on detected communications between the at least one node and at least one intermediate node or at least one leaf node via the wireless network protocol.
