    Abstract: Embodiments of this application provide a data sending method, a data receiving method, a transmit-end device, and a receive-end device. The data sending method provided in the embodiments of this application may include: performing scrambling code initialization to generate a scrambling code; scrambling a data block based on the scrambling code; repeatedly sending the scrambled data block; performing scrambling code initialization to generate a new scrambling code when an interval after previous scrambling code initialization of the data block is greater than or equal to a preset scrambling code initialization parameter threshold; scrambling the data block again based on the generated new scrambling code; and repeatedly sending the data block scrambled again. The embodiments of this application can improve efficiency of data transmission between a transmit-end device and a receive-end device.

    Abstract: Embodiments of the present invention disclose a downlink control information DCI transmission method, a network device, and user equipment. The method includes the following steps: A network device transmits DCI in a first DCI format; when the DCI is used to schedule a physical downlink shared channel PDSCH carrying a multicast traffic channel, the network device indicates, by using a first radio network temporary identifier RNTI, that the DCI is used to schedule the PDSCH carrying the multicast traffic channel, and that first information is indicated in the DCI and second information is not indicated in the DCI; and when the DCI is used to schedule a user equipment-specific UE-specific PDSCH, the network device indicates, by using a second RNTI, that the DCI is used to schedule the UE-specific PDSCH, and that the first information is not indicated in the DCI and the second information is indicated in the DCI. In this application, an indication indicating that configuration information of an MTCH changes is implemented in DCI without adding a bit to the DCI, so that control channel transmission performance is improved.

    Abstract: This application provides a channel transmission method, apparatus, and system for NB-IoT. An NB-IoT base station determines, based on the frequency hopping information, a time-frequency resource location of the channel after frequency hopping, and performs channel transmission with an NB-IoT terminal on a time-frequency resource corresponding to the time-frequency resource location, so that the frequency hopping is introduced into the NB-IoT, thereby increasing a gain of frequency diversity through the frequency hopping.

    Abstract: The present invention discloses a paging method, a paging device, a core network device, a base station, and a paging system. The method includes: transmitting, by a core network device, a paging message to at least one base station in a paging area, where the paging message includes an identifier of UE paged by the core network device; receiving a response message transmitted by the at least one base station, where each response message includes time information correlated with a paging time point of the UE and determined according to the identifier of the UE by the base station that transmits the response message, and the paging time point is a time point of receiving the paging message by the UE; and determining timing duration of a paging timer according to the time information included in each response message, and starting the paging timer, so that the core network device can accurately obtain the time information correlated with the paging time point of the UE, and a core network can properly configure the timing duration of the paging timer, thereby effectively ensuring that the paging message can be transmitted to the UE before the paging timer expires, avoiding repeated transmitting of the paging message from the core network device, and saving air interface resources.
