Provided are a method and apparatus for sending and receiving a multiframe, a communication device, and a communication network system. The method includes: determining a multiframe identifier used for identifying a multiframe number according to a number of timeslots of a physical layer, where the multiframe number is the number of frames constituting one multiframe; and sending the multiframe to a receiving end, where the multiframe carries the multiframe identifier. Further provided is a computer storage medium.

The present disclosure is directed to a device and method for generating and transmitting a TDM signal including both raw data and processed data. The device includes a sensor having a time division multiplexing (TDM) interface. The TDM interface transmits both raw data and processed data in a single TDM signal by reserving one or more slots inside a TDM frame for transmission of the processed data. The sensor also embeds additional information inside a data stream of raw data by repurposing one or more of values of the raw data as an exception code, flag, or another type of notification. The device is also enabled to transmit data, and disabled when not in use in order to conserve power.

Provided are a method for determining and sending a multiframe, and a communication device. The method includes: for physical layers of different interface bandwidth speeds, determining a multiframe number of the multiframe to be n-th power of 2, where n is a minimum positive integer that causes the multiframe number greater than or equal to a number of timeslots of a physical layer, identifier values of the multiframe identifier for identifying the multiframe number are sequentially carried in preset positions of overhead blocks of respective frames constituting the multiframe, and the number of the identifier values of the multiframe identifier is the same as the multiframe number. The identifier values of the multiframe identifier are a preset number of consecutive “0”s and the preset number of consecutive “1”s in sequence.

Systems and methods are described, and one method includes allocate a continuous duration within a TDMA scheme, for asynchronous NOMA transmissions, and extending from an allocation start time to an allocation termination time, formed of contiguous time slots of the TDMA scheme, and included providing to asynchronous NOMA user terminals an indication of the allocation start time and termination time, indicating allowance to perform asynchronous NOMA transmissions within a start time constraint that starts of the asynchronous NOMA transmissions do not precede the allocation start time, and terminations of the asynchronous NOMA transmissions do not succeed the allocation termination time.

Embodiments provide a service processing method and apparatus. According to the service processing method, a number of code blocks of a client service may be mapped to a FlexE subslot, and a FlexE subslot overhead is generated, so that the client service mapped to the FlexE subslot and the FlexE subslot overhead are sent through a physical channel, and a low-rate service is carried. Compared with carrying a low-rate service by directly using an entire FlexE slot, carrying the client service by using a number of FlexE subslots into which the FlexE slot is divided can improve bandwidth utilization.
