A network adapter includes a host interface configured to communicate with a host, a network interface configured to communicate with a communication network, and packet processing circuitry. The packet processing circuitry is configured to receive a packet from the host via the host interface, or from the communication network via the network interface, to receive an indication of a network time used for synchronizing network elements in the communication network, to match the packet to a rule, the rule including a condition and an action, and to perform the action in response to the packet meeting the condition, wherein one or more of (i) the condition in the rule and (ii) the action in the rule, depend on the network time.

A method and apparatus may include receiving, by a radio access network (RAN), at least one burst arrival time (BAT) parameter from at least one session management function (SMF). The method may further include determining, by the RAN, if at least one actual BAT is offset from the at least one received BAT parameter by at least one threshold. The method may further include setting, by the RAN, at least one BAT correction parameter based upon at least one offset time. The method may further include calculating, by the RAN, at least one new BAT parameter according to the one BAT correction parameter. The method may further include adjusting, by the RAN, at least one burst schedule based upon one or more of the at least one BAT correction parameter or the at least one new BAT parameter.

Systems and methods are disclosed for random access in a wireless communication system such as, e.g., a wireless communication system having a non-terrestrial (e.g., satellite-based) radio access network. Embodiments of a method performed by a wireless device and corresponding embodiments of a wireless device are disclosed. In some embodiments, a method performed by a wireless device for random access comprises performing an open-loop timing advance estimation procedure to thereby determine an open-loop timing advance estimate for an uplink between the wireless device and a base station. The method further comprises transmitting a random access preamble using the open-loop timing advance estimate. In this manner, random access can be performed even in the presence of a long propagation delay such as that present in a satellite-based radio access network. Embodiments of a method performed by a base station and corresponding embodiments of a base station are also disclosed.

In retrodirective wireless power delivery environments wireless power receivers generate and send beacon signals that are received by multiple antennas of a wireless power transmission system. The beacon signals provide the charger with timing information for wireless power transfers and also indicate directionality of the incoming signal. As discussed herein, the directionality information is employed when transmitting in order to focus energy (e.g., power wave delivery) on individual wireless power receiver clients. Techniques are described herein for reducing the burden of sampling the beacon signals across the multiple antennas and determining the directionality of the incoming wave. In some embodiments, the techniques leverage previously calculated values to simplify the receiver sampling.

Disclosed is an improved implementation of a flood fill mesh network that utilizes probability forwarding for rebroadcasting network messages. The forwarding probability may be determined based on analyzing a network topology map constructed by each network node relative to its neighbor nodes communicating on the network and derived from state information contained in synchronization frames broadcasted by the network nodes on the network. The forwarding probability may comprise a statistical probability that a message frame received by a network node will be forwarded to the intended destination network node by one or more of the network node's neighbor network nodes.

Disclosed is an improved implementation of a flood fill mesh radio network that utilizes message age disambiguation to prevent unnecessary propagation of repeated messages in the network. A digital counter may be used to generate a sequence of numbers based on counter values and the counter values may be associated with each message frame that is broadcast into the mesh network. The domain of generated sequence numbers can be divided up into low and high subdomains and the maximum number of message frames broadcast by a network node in the mesh network may be constrained so that no two messages broadcast by a network node remain circulating in the network longer than that required for the digital counter to wrap back to zero. Under this paradigm the counter values associated with each message can be compared to determine the relative age of the message frames to detect repeated messages.

Disclosed is an improved implementation of a flood fill mesh network that utilizes low power and does not require any network addressing or routing protocol for network message delivery. Network messages are only communicated to a network node's correspondents using broadcast network messages over a wireless network. Network messages propagate throughout the network based on each correspondent node rebroadcasting received messages to its correspondent nodes, and so on. Coordinated synchronization across network nodes can be achieved by each network node broadcasting synchronization frames to its correspondents within a synchronization window time period and thereafter adjusting its own start time for the next synchronization period to converge synchronization. A guard band may also be utilized to account for any clock drift and signal path delays between any two communicating network nodes.
