Systems and methods for one-way time transfer using physical layer signaling are disclosed herein. According to some examples, a method includes generating timing information based on a clock of a transmitting device, where the timing information comprises a timestamp and metadata. The method further includes generating a preamble of a frame, where the preamble includes the timestamp and the metadata of the timing information. The method also includes forming a frame, where the frame comprises a bootstrap, the preamble, and a payload, and transmitting the frame to a receiver device. The one-way time transfer systems and methods of this disclosure can serve mobile devices that entail quick and reliable establishment of a clock.

The present technology relates to a signal processing device and a method thereof that inhibits deterioration in reception sensitivity. In a case where a frequency band is vacant on the basis of a result of carrier sense, a data frame is transmitted as a wireless signal in the frequency band, and further, a synchronous frame formed of predetermined information different from that of the data frame is transmitted as a wireless signal in the frequency band in a case where the data frame is transmitted predetermined number of times within first time. In a case where the synchronous frame is detected, the data frame is detected from a reception signal of predetermined time before the synchronous frame.

Network discovery and synchronization for new radio (NR) shared spectrum (NR-SS) is discussed for a wireless network having a super frame configuration on a shared spectrum shared between a plurality of network operators. A base station may obtain a discovery preamble from a plurality of network entities within the wireless network, wherein each of the plurality of network entities belongs to one or more of the plurality of network operators and shares the super frame configuration. The base station detects the timing of the super frame configuration using the discovery preamble and may then synchronize the base station to the super frame configuration according to the detected timing.

The disclosure relates to detecting phase slips in a data link. An apparatus may perform a frame resynchronization when a phase slip is detected. The apparatus may generate a reference phase signal that is compared to incoming data frames to determine whether a phase slip occurred and characterize the phase slip. The counter may be based on a recovered receiver clock, thereby counting an actual number of bits received, and may wrap based on the frame size. A value of the counter latched to an incoming frame before the frame resynchronization may be compared to a latched value of the counter after the frame resynchronization to determine whether a phase slip, a size of the phase slip, and a direction of the phase slip.

An electronic device is provided including a processor, a communications interface coupled to the processor, a memory coupled to the processor, and a module saved in the memory. The module configures the processor to receive a first communications packet from a remote device via the communications interface including information useful for estimating a clock offset of the remote device, and determine an upper bound of the clock offset of the remote device with respect to the electronic device based on the information.

A system for communicating between electronic devices on a communication bus includes a communication bus and one or more communication circuits each having an output driver coupled to the communication bus and each having an input terminal. Each communication circuit produces, in response to a request message, a data communication on the communication bus in a predetermined order with respect to data communications from other communication circuits so that the data communications from each communication circuit form a sequential data stream in response to the request message.
