Abstract: A data transmission method and apparatus to reduce terminal power consumption and ensure transmission reliability during uplink data transmission is provided. The method includes: A terminal transmits first uplink data to a network device on a non-dynamically scheduled resource. The terminal receives response information for the first uplink data from the network device, where the response information is used to indicate whether the first uplink data is successfully received. The response information is further used to indicate whether the terminal monitors a physical downlink control channel PDCCH under a configured condition. If the response information indicates the terminal not to monitor the PDCCH under the configured condition, the response information may be further used to indicate to transmit second uplink data by using the non-dynamically scheduled resource under the configured condition.

Abstract: A frequency hopping pattern indication method and an apparatus are provided to reduce interference between users. In the method, a network device may indicate a frequency hopping pattern to a first terminal device which performs communication based on the frequency hopping pattern. The frequency hopping pattern indicates a frequency band occupied when the first terminal device performs communication at a frequency hopping moment. The first terminal device collides with any other terminal device at a maximum of one frequency hopping moment in one period. A first period corresponds to more than two frequency hopping moments and more than two frequency bands.

Abstract: A network device sends downlink control information to a first terminal device. The downlink control information includes: time domain resource information, where the time domain resource is a time domain resource on which a first data channel is located; and frequency domain resource information, where the frequency domain resources are a frequency domain resource on which the first data channel is located and a frequency domain resource on which a second data channel is located. The second data channel is located on a time domain resource different from the time domain resource on which the first data channel is located. The first terminal device receives, on the determined time domain resource and frequency domain resource, a signal that is located on the first data channel and that is from the network device.

Abstract: A data transmission method, a terminal, and a network device are provided. In embodiments of the present disclosure, a terminal sends, in a grant-free mode, first data to a network device by using a grant-free resource, and if the terminal needs to switch from the grant-free mode to a grant mode, the terminal sends, in the grant mode, second data to the network device by using a grant resource. When the terminal initially transmits the first data in the grant-free mode, if the terminal needs to switch from the grant-free mode to the grant mode, the terminal may fall back to the grant mode and transmit data in the grant mode.
