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.

A system, a method, and a computer program product for transmission of data using a multiple input, multiple output communications system with hybrid beamforming in a layer 1 split architecture. A first portion of a signal is processed at a first portion of a physical layer located in a first portion of a base station. A frequency domain compression with statistical multiplexing is applied to the processed first portion of the signal. A compressed first portion of the signal is generated. The compressed first portion of the signal and a second portion of the signal are transmitted to a second portion of the physical layer located in a second portion of the base station.

Disclosed is a method for allowing a terminal to transmit and receive signals to and/from a base station in a wireless communication system using a time division multiplexing method. Specifically, the method comprises the steps of: receiving a request signal for resetting into a second uplink/downlink setting while transmitting and receiving a signal according to a first uplink/downlink setting; terminating an uplink retransmission process associated with a specific uplink subframe when the use of the specific uplink subframe is changed into a downlink subframe according to the second uplink/downlink setting; and applying the second uplink/downlink setting at a specific time point to transmit and receive signals.

TDMA communications between a host device and a number of clients on a communications channel are dynamically adapted to allocate or de-allocate time slots in response to changes in the number of active clients. The system initially operates in a startup mode in which the host device transmits a startup message on the communications channel and assigns a timeslot in a TDMA cycle in response to connection requests received from each of the requesting clients. After exiting the startup mode, the system operates in a normal mode in which the host device initiates the TDMA cycle by transmitting a polling message on the communications channel that indicates a number of timeslots occurring within that particular TDMA cycle. The host changes the number of timeslots indicated in the polling message to responsively adapt duration of the TDMA cycle as the number of clients communicating via the communications channel changes.

Dynamic bandwidth selection based on environmental conditions is described. A bandwidth of a sub-bandwidth may be selected based on signal strength, channel interference, or overlap to optimize throughput and/or energy per bit. Additionally, system power level may define a communication bandwidth.

A radio frequency capability configuration method and an apparatus, the method including sending, by a network device, to a terminal, configuration information configuring M sets of radio frequency capabilities, where each set of radio frequency capabilities includes one or more radio frequency capabilities on one or more carriers, where a radio frequency capability on each carrier of the one or more carriers comprises a quantity of multiple-input multiple-output (MIMO) layers, and where M is an integer greater than 1, and sending, by the network device, to the terminal, first indication information to the terminal, where the first indication information indicates a set of radio frequency capabilities in the M sets of radio frequency capabilities.

A multiplexing communication system is capable of maintaining an appropriate response speed of a control with respect to an electromagnetic motor based on an encoder signal during multiplexing and transmission of the encoder signal. A transmission data composition processing section of a multiplex communication device multiplexes encoder signals ENCD1 to ENCD8 output from a linear scale and a rotary encoder into frame data FRMD and transmits the data. The transmission data composition processing section sets the encoder signals ENCD1 to ENCD8 to bit positions of the frame data FRMD respectively corresponding to the linear scale and the rotary encoder. At the bit positions where the encoder signals ENCD1 to ENCD8 are set, the encoder signal ENCD and information showing the presence or absence of the data of the encoder signal ENCD are alternately set for each cycle of transmission of the frame data FRMD.

Methods and apparatus for performing multiplexing of video or other content (e.g., programs) within a network using feed-back from a subsequent digital program insertion stage, and/or feed-forward information from a prior multiplexing stage. In one embodiment, the network comprises a hybrid fiber coax (HFC) cable network having headend and hub-based statistical multiplexing stages, and communication between the two stages is used to improve the visual quality performance and bandwidth utilization of the output multi-program stream during conditions where downstream content is inserted into the transport stream. Business methods associated with the various multiplexing features described above are also disclosed.

A multiplexer includes filters connected to each other at a common terminal, a low-frequency filter with a first pass band, and a high-frequency filter with a second pass band that is higher than the first pass band.

A reflection coefficient in the second pass band when the initial-stage filter section is viewed from the common terminal side as a single component is larger than a reflection coefficient in the second pass band when the subsequent-stage filter section is viewed from the common terminal side as a single component.
