摘要： This application provides a multicast broadcast service sending method, an apparatus, and a system, so that a multicast broadcast service can be properly configured and sent when a receiver of the multicast broadcast service includes a narrowband terminal and a broadband terminal, to reduce resource overheads as much as possible. The method includes: An access network device receives indication information from a core network device, learns that a receiver of a target multicast broadcast service includes a narrowband terminal and a broadband terminal, sends an MCCH to the narrowband terminal and the broadband terminal, and sends a multicast broadcast service to the narrowband terminal and the broadband terminal on a frequency domain resource corresponding to an MTCH of the target multicast broadcast service. Configuration information of the MTCH is carried in the MCCH. Correspondingly, after receiving the MCCH, the narrowband terminal and the broadband terminal receive the target multicast broadcast service on the frequency domain resource corresponding to the MTCH. A first frequency domain resource corresponding to the MCCH or a scheduling bandwidth occupied by the MCCH does not exceed a maximum bandwidth capability of the narrowband terminal.

摘要： Embodiments of this application provide a communication method and apparatus, to indicate a subframe type, so that idle subframes are used as much as possible, to increase a peak rate of a terminal. The method includes: receiving downlink control information, determining a first delay based on the downlink control information, and receiving data on a physical downlink shared channel based on the first delay. The downlink control information indicates the first delay. The first delay includes five or six subframes, and the first delay includes a subframe type 1 or a subframe type 2. The subframe type 1 includes the following in sequence: one downlink BL/CE subframe, one first subframe, X uplink BL/CE subframes, one second subframe, and one first downlink BL/CE subframe. The first downlink BL/CE subframe is used to receive the physical downlink shared channel scheduled by a physical downlink control channel. The subframe type 2 includes the following in sequence: the one first subframe, the X uplink BL/CE subframes, the one second subframe, the first downlink BL/CE subframe, and one second downlink BL/CE subframe. The second downlink BL/CE subframe is used to receive the physical downlink shared channel.

摘要： An information sending method, an apparatus, and a system are provided, so that a quantity of terminal devices can be obtained. In the method, a network device sends first information by using a first message, where the first information is used to indicate a terminal device to send second information on one or more first resources. Each terminal device that receives the first message may send the second information on a part of or all of the one or more first resources based on the first information included in the first message, where the first message may be a broadcast message or a paging message. The network device receives the second information on the one or more first resources. After receiving the second information, the network device may estimate a quantity of terminal devices within coverage of the network device based on a quantity of pieces of received second information, or a quantity of times of receiving the second information, to obtain the quantity of terminal devices.

摘要： This application relates to a communication method and apparatus. A terminal device sends first uplink data to a network device. After sending the first uplink data, the terminal device monitors a first downlink control channel in a first search space in a first duration; and after the first duration ends, the terminal device monitors a second downlink control channel in a second search space in a second duration. A length of a periodicity of the second search space is greater than a length of a periodicity of the first search space. In this case, the terminal device monitors the second downlink control channel based on the second search space at a low frequency. Therefore, the second search space with a long periodicity is set, so that power consumption of monitoring the downlink control channel by the terminal device can be reduced.
