Abstract: Embodiments of this application provide a communication method and a communications apparatus. Therefore, when an operating bandwidth of a terminal device is a narrow bandwidth, time-frequency synchronization is performed on a resource with a relatively small bandwidth, to implement network communication. This avoids a communication failure and improves communication efficiency. In the method, a network device sends first indication information to a terminal device, where the first indication information indicates a relative location between a first resource and a second resource, the first resource carries a synchronization signal block, the synchronization signal block includes a first system message, the second resource carries a second system message, and a bandwidth of the second resource is less than a bandwidth of the first resource.

Abstract: In a resource allocation method, after determining a BWP allocated to a terminal device, where the BWP includes a first BWP, and determining a first value, a network device sends first indication information to the terminal device, where the first indication information is used to indicate the first value. The terminal device determines the BWP allocated by the network device to the terminal device, where the BWP includes the first BWP, and receives the first indication information from the network device. Then, when the first value is used to indicate a RBG size corresponding to the first BWP, the RBG size corresponding to the first BWP is determined based on the first value. Alternatively, when the first value is used to determine a RIV set corresponding to the first BWP, the RIV set corresponding to the first BWP is determined based on the first value.

Abstract: This application provides example communication methods and apparatuses. One example method includes performing, by a network device on a preconfigured resource, data demodulation on uplink data from a terminal device. The network device can then send downlink control information (DCI) to the terminal device, where the DCI includes first indication information, and if the uplink data fails to be demodulated, or it is determined, based on a result of the data demodulation, that the terminal device needs to retransmit the uplink data, the first indication information indicates either the terminal device to initiate random access or EDT and retransmit the uplink data or that the uplink data fails to be demodulated.

Abstract: This application discloses a method for requesting an uplink transmission resource, a terminal, and a network device. The method includes: determining, by a terminal, that a collision occurs when the terminal sends a first request to a network device, where the first request is used to request the network device to schedule an uplink transmission resource for the terminal; and adjusting, by the terminal according to a preset rule, a manner of sending the first request. In embodiments of this application, the terminal may request the uplink transmission resource from the network device by using the first request. This avoids a prior-art problem that a terminal can request an uplink transmission resource from a network device only by initiating a random access procedure, and improves flexibility of requesting an uplink transmission resource by the terminal from the network device.

Abstract: A gap determining method includes: A terminal device receives first configuration information and second configuration information from a network device. The terminal device receives scheduling information from the network device. The terminal device determines a downlink gap of the first channel based on the first configuration information. The terminal device determines a first gap between the N transport blocks based on the second configuration information. When the terminal device determines that a preset condition is satisfied, the terminal device determines that a gap part that is included in the first gap and that overlaps with the downlink gap is postponed in time domain and that a gap part obtained through postponing does not overlap with the downlink gap; or when the first gap includes a gap part that overlaps with the downlink gap, the terminal device determines that the gap part belongs to the downlink gap.
