A radio link monitoring method, the method includes: generating an indication indicating that a reference signal is not detected if the reference signal is not detected; and performing radio link monitoring according to the indication.

A method for avoiding collision over a communication network, wherein devices are connected to the same medium. Each device has an access control module, a transceiver and a data exchange module. The access control module is configured to transmit data to the data exchange module when it receives information that no data is present on the medium. The transceiver is configured to transmit data on the medium each time it receives data from the data exchange module. The data exchange modules of all the devices are synchronized and then offered, in sequence, the opportunity to transmit data on the medium. The opportunity to transmit is offered dynamically after a previous transmission end or, if no transmission occurred, after a predetermined time range has expired. The data exchange module transmits data to the transceiver of the same device only when it is offered the opportunity to transmit.

A method includes communicating, between a first device and a second device, a scheduling control message indicative of first time-frequency resources for a first uplink reference signal transmission from the second device to the first device and further indicative of second time-frequency resources for a second uplink reference signal transmission from the second device to the first device. Wherein the first uplink reference signal transmission is associated with a receive beam having a first opening angle. Wherein the second uplink reference signal transmission is associated with a receive beam having a second opening angle. The first opening angle is smaller than the second opening angle. Furthermore the first uplink reference signal transmission is beam swept at the first device, and the second uplink reference signal transmission is not beam swept at the first device.

A sensor may determine a sampling pattern based on a group of synchronization signals received by the sensor. The sampling pattern may identify an expected time for receiving an upcoming synchronization signal. The sensor may trigger, based on the sampling pattern, a performance of a sensor operation associated with the upcoming synchronization signal. The performance of the sensor operation may be triggered before the upcoming synchronization signal is received.

A communication device is presented that includes a receiver operatively coupled to a processor. The receiver receives communication data from other communication devices. The device also includes a speaker operatively coupled to the processor. The speaker is configured to output a sound wave based on an output from the processor. The processor determines a distance from another communication device transmitting communication data to the communication device. A volume of the sound wave is reduced in proportion to the distance between the communication device and the other device.

A multimedia system applying ToF ranging and its operating method are provided. The multimedia system includes a plurality of electronic devices. Each of the electronic devices includes a processing module, a ToF module, and a communication module. The ToF module is configured to perform a ToF operation.

According to embodiments, a timing slice is configured to provide the portion of timing resources that are associated with the delivery of timing to a slave device in an environment where multiple network slices are operating.

A receiver device may include a receiver and one or more processors. The receiver device may be configured to receive a first set of frames from a first device indicating a transmit time of the first set of frames, and a second set of frames from a second device indicating a transmit time of the second set of frames and an arrival time of the first set of frames. The receiver device may be configured to determine a first transmission delay based on the transmit and arrival times of the first set of frames, and determine a second transmission delay based on the transmit and arrival times of the second set of frames. The receiver device may be configured to transmit a third set of frames indicating the arrival times of the first and second sets of frames, and a transmit time of the third set of frames.

Provided is a computation device including a communication interface; a first transmission control part for sending a first communication frame at every predetermined cycle via a transmission path; a second transmission control part for sending a second communication frame in response to an arbitrary event request; and a priority management part. Upon receiving an issuance request of a second event request from a second event issuance part, the priority management part waits for completion of sending processing for a second communication frame corresponding to a first event request currently processed by the second transmission control part, and permits issuance of the second event request to the second event issuance part. The second transmission control part suspends processing for a subsequent first event request following the first event request currently processed until completion of processing for the second event request is complete.
