Abstract: System information block transmission methods and communication apparatus are provided to resolve a problem that a terminal device cannot receive, on an active bandwidth part, a system information block broadcast by a network device. A network device sends a system information block to a terminal device through a first bandwidth part. When determining that a first moment satisfies a preset condition, the network device sends the system information block to the terminal device through a second bandwidth part, where the system information block is included in first dedicated signaling, and configuration information for sending the system information block by the network device is not configured on the second bandwidth part.

Abstract: Embodiments of this application provide a communication method and an apparatus. A correspondence between a plurality of MCS indexes and a plurality of modulation schemes is provided to achieve flexible selection of a modulation scheme. In the correspondence, at least one MCS index of the plurality of MCS indexes corresponds to a set modulation schemes which comprises π/2 binary phase shift keying (π/2-BPSK) modulation and quadrature phase shift keying (QPSK) modulation. A first communication device receives a target modulation and coding scheme (MCS) index from a second communication device, determines a target modulation scheme corresponding to the target index number based on the correspondence, and performs communication with the second communication device based on the target modulation scheme.

Abstract: A method and an apparatus are provided. The method includes: An access network device sends DCI for a paging message to a terminal device, where the DCI includes scheduling information for downlink data. The access network device further sends first indication information included in the paging message to the terminal device, wherein the first indication information indicates that first downlink data corresponds to the terminal device. Therefore, when determining that there is downlink data to arrive, the terminal device determines a time-frequency location of the downlink data based on the scheduling information that is for the downlink data and that is in the DCI, and then receives the downlink data at the time-frequency location. According to the method and the apparatus provided in this application, a small amount of downlink data is transmitted, resource utilization is improved, and power consumption of the terminal device is reduced.
