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.

Abstract: In a control channel resource transmission method, user equipment (UE) obtains a configuration parameter in a candidate control channel set according to a preset protocol and/or higher-layer signaling sent by a base station, where the higher-layer signaling is used to notify the configuration parameter. The UE determines an antenna port according to the obtained configuration parameter, and then receives, through the antenna port, a control channel or a control channel element sent by the base station. The base station determines the antenna port according to the same configuration parameter as that of the user equipment, and sends, by using the antenna port, the control channel or the control channel element to the user equipment.

Abstract: A user equipment (UE) receives control signaling in a scheduling bandwidth part (BWP). The control signaling indicates switching from a first active BWP to a second active BWP or switching from a first active BWP pair to a second active BWP pair for the UE. The control signaling aligns with a time unit boundary, such as a slot boundary, that is associated with the scheduling BWP. In the event that a scheduled BWP for a UE has a different numerology than a scheduling BWP that is currently active for the UE, the UE could switch from the scheduling BWP to the scheduled BWP based on a control signaling monitoring periodicity of the scheduled BWP.

Abstract: This application provides a resource mapping method and a device. A network device writes n physical resource block groups into an interleaving matrix row by row, where N null values are inserted into intersections between the first row and the last N columns of the interleaving matrix or intersections between the last row and the first N columns of the interleaving matrix, n is a positive integer, and N is a natural number; reads the n physical resource block groups from the interleaving matrix column by column, where the n read physical resource block groups are mapped to n virtual resource block groups; and determines, based on the n physical resource block groups mapped to the n virtual resource block groups, physical resource blocks mapped to virtual resource blocks in the n virtual resource block groups.
