Abstract: This application provides a resource configuration method. The method includes: generating, by a network device, a first signal; and sending, by the network device, the first signal to a terminal device at a target resource location. The target resource location includes at least one subframe, and the at least one subframe is an invalid subframe. This implements that the network device sends the first signal in the invalid subframe. Based on a mechanism of the invalid subframe, a terminal device that does not need to receive the first signal may postpone the invalid subframe, and a terminal device that needs to receive the first signal may receive the first signal in the invalid subframe.

Abstract: This application discloses a data transmission method and an apparatus. The method includes: A network device generates downlink control information DCI. The DCI indicating a first modulation scheme or a second modulation scheme. The DCI includes a modulation and coding scheme MCS field. The DCI indicates the first modulation scheme when the MCS field is in a first state, or the DCI indicates the second modulation scheme and an MCS index of the second modulation scheme when the MCS field is in a second state. The network device sends the DCI. A terminal receives the downlink control information DCI, and receives or sends data based on the DCI. In embodiments of this application, the first modulation scheme, the second modulation scheme, and the MCS index of the second modulation scheme are indicated by using different states in the MCS field, to support a new modulation scheme without increasing DCI overheads.
