Abstract: A resource indication method, a device, and a system relate to the field of communications technologies. The method includes: allocating, by a base station, a BP to a terminal device, and sending, to the terminal device, a first message indicating a resource position of the BP; and receiving, by the terminal device, the first message sent by the base station, and then determining the resource position of the BP based on resource position information of at least one sub-BP, where the BP includes the at least one sub-BP, the BP is not greater than a maximum bandwidth supported by the terminal device, and the first message includes the resource position information of the at least one sub-BP. The BP is allocated by using a sub-BP as a granularity, so that signaling overheads can be reduced while a requirement for more flexible resource allocation is satisfied.

Abstract: A method for determining time information is disclosed. The method includes: obtaining, by a network node, information sent by a terminal device; and determining, by the network node, at least one of the following based on the information: a first time interval between downlink scheduling and downlink data transmission, a second time interval between the downlink data transmission and a feedback message sent by the terminal device after the terminal device receives downlink data, and a third time interval between uplink scheduling and uplink data transmission, where the information may include at least one of a subcarrier spacing, an operating band, and a bandwidth that are supported by the terminal device, and further include a first smallest value and/or a second smallest value and/or a third smallest value corresponding to the at least one item. Therefore, flexibility and accuracy of determining the time information are improved.

Abstract: Embodiments described provide a data transmission method, a network device, and a terminal device. The method includes: sending, by a network device, control information corresponding to target data to a terminal device on a control resource, where the control resource and a data resource have a correspondence, and the control resource is used by the terminal device to determine the data resource on which the target data is received; and sending, by the network device based on the correspondence, the target data to the terminal device on the data resource. In the embodiments, after sending the control information corresponding to the target data on the control resource, the network device can send the target data on the data resource based on the correspondence between the control resource and the data resource, so that terminal devices having different bandwidth capabilities are able to receive the target data.
