A bandwidth allocation device is included in a communication system having a terminal station device and a terminal device and relaying upstream data, which is received from a communication terminal by a lower device connected to the terminal device, to an upper device connected to the terminal station device. The bandwidth allocation device includes a transmission-permitted period start position determining unit configured to estimate a start position of an arrival period in which the upstream data arrives at the terminal device from the lower device; a transmission-permitted period length determining unit configured to estimate a length of the arrival period based on an amount of upstream data to be transmitted from the lower device to the terminal device; and a bandwidth allocation unit configured to allocate a bandwidth to the terminal device based on the estimated start position and the estimated length of the arrival period.

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.

Based on a count value held by a transmission counter, an information multiplex apparatus forms multiplexed transmission data by selecting or dividing at least part of each of two or more information items, based on the respective sizes of the two or more information items, a counter period of the transmission counter, and a transmission margin degree.

A method includes: obtaining a transmission bandwidth granularity G1 of a target service and an optical-layer spectrum resource of a target fiber channel corresponding to the target service, where the optical-layer spectrum resource includes N consecutive frequency slots, and all of the N consecutive frequency slots have a same spectrum bandwidth; determining a target spectrum slice from the N frequency slots based on the transmission bandwidth granularity G1, where the target spectrum slice includes N1 consecutive frequency slots, and the target spectrum slice includes at least G1 consecutive idle frequency slots; and allocating the G1 consecutive idle frequency slots included in the target spectrum slice to the target service.

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.
