A vehicular autonomous driving system includes a time division multiplexed (TDM) bus, an autonomous driving (AD) controller coupled to the TDM bus, and a plurality of AD sensors coupled to the TDM bus. The AD sensors are configured to collect AD data and transmit collected AD data to the AD controller on the TDM bus in an assigned time slot at a first power level. A first AD sensor of the plurality of AD sensors is configured to, based upon collected AD data, detect an AD emergency event. In response to the detection, the first AD sensor is configured to transmit an AD emergency message on the TDM bus in a non-assigned time slot and at a second power level that exceeds the first power level. The AD sensor may transmit the AD emergency message in a particular sub-slot of the non-assigned time slot.

The present disclosure relates to a reception apparatus and method, a transmission apparatus and method, and a program, capable of obtaining desired communication quality. Under the control of a central control unit, a tactile signal generation unit generates a tactile signal of a necessary number. Under the control of the central control unit, a header generation unit generates header information including the presence or absence of the tactile signal (that is, information indicating whether or not the tactile signal is to be used for each of vibration units as information associated with the vibration unit that uses the tactile signal), the delay amount, and the magnitude. A signal coupling unit adds header information to each of the tactile signals from the tactile signal generation unit, and performs time-division multiplexing on each of the tactile signals to which the header information has been added. The present disclosure can be applied to a tactile presentation system that vibrates a wearable reception apparatus including the vibration unit, for example.

An apparatus communicates using a first Radio Access Technology (RAT) and a second RAT. The apparatus receives a first Time Division Duplex Uplink/Downlink (TDD UL/DL) configuration for a first cell using the first RAT. The apparatus also receives a second TDD UL/DL configuration for a second cell using the first RAT. Additionally, the apparatus determines a maximum transmission power for a first transmission using the second RAT based on whether there is a potential overlap between the first transmission using the second RAT and a possible transmission based on the first TDD UL/DL configuration or the second TDD UL/DL configuration during a period of the first transmission or an extended period including the first transmission period.
