Abstract: A communication method and apparatus are provided, and relate to the field of communication technologies, to support a radio frequency identification RFID system in segmenting data based on a segmentation mechanism, simplify the segmentation mechanism, and reduce segmentation overheads. The method may be applied to the RFID system. A first protocol layer of a terminal device obtains first information that indicates a transport block size. If a size of a first data packet is greater than the transport block size, the first protocol layer segments the first data packet based on the transport block size, to obtain a plurality of first segmented data packets, and sends the plurality of first segmented data packets. The first data packet is a data packet received by the first protocol layer from a previous protocol layer. A size of the first segmented data packet is less than or equal to the transport block size.

Abstract: This application provides a communication method and a communication apparatus. In the method, M amplitude shift keying modulation symbols included in a first signal sent by a signal sending device are the same as M amplitude shift keying modulation symbols included in a second signal. In addition, bandwidth occupied by a first frequency domain signal of the first signal in frequency domain is half of that occupied by a second frequency domain signal of the second signal in frequency domain. In addition, the first signal is one OFDM symbol in time domain, and duration of the M amplitude shift keying modulation symbols carried by the first signal is the same as that of the M amplitude shift keying modulation symbols carried by the second signal.

Abstract: A data transmission method and a device thereof are provided for tag access. The provided method includes: An answer device receives first signaling sent by a read/write device. The first signaling carries target flag information. The target flag information is used to determine the answer device. First flag information of the answer device matches the target flag information. The answer device determines a first slot, and sends first access information to the read/write device in the first slot. In the provided method, the first slot is determined, to avoid collision of different slots in a same slot in a next round, reduce a collision probability, and improve tag access efficiency.

Abstract: The signal transmitting method includes that a transmit end modulates a first frequency band that corresponds to a first signal to be transmitted by the single carrier system onto a second frequency band that corresponds to a second signal to be transmitted by the multicarrier system, to obtain a transmit signal including at least the first signal and/or the second signal. A spacing between a center frequency of a first subchannel and a center frequency of a second subchannel is an integer multiple of a spacing between two adjacent second subchannels. A signal bandwidth that corresponds to the first subchannel is less than or equal to a signal bandwidth that corresponds to the second subchannel. The method includes transmitting the transmit signal to a receive end for completing reception of the first signal and the second signal.
