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: Embodiments of this disclosure provide a paging method and an associated communication apparatus, medium, and chip. According to embodiments of this disclosure, an access network device sends information including an address of the access network device and an identifier of a terminal device to a core network device. The core network device determines an area for paging based on the address of the access network device, and sends a paging message including the identifier of the terminal device to the access network device. The access network device sends a radio access network paging message to the terminal device. In this manner, the area in which paging needs to be performed by the core network device can be reduced, thereby avoiding a waste of unnecessary paging resources.

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: This application relates to the field of wireless communications technologies, and in particular, to a system message transmission technology, so as to resolve a system message update problem of a terminal device with DRX cycle. This application provides a terminal device, including: a receiving module, configured to receive a first system message; and a processing module, configured to: obtain first indication information from the first system message, and update system messages other than the first system message according to the obtained first indication information, where the first system message is periodically sent, and occupies a fixed physical resource location. The first indication information is sent in the first system message instead of a paging message. The terminal device may update the system messages other than the first system message according to the indication information, thereby updating all system messages.
