Abstract: A transmission resource mapping method and a device relating to the field of mobile communications technologies, where resource mapping is performed using a resource element block, a length of the resource element block in time domain is less than a length of a physical resource block in the time domain. Therefore, a mapping granularity can be reduced during resource mapping such that latency in a transmission process can be reduced.

Abstract: A self-contained subframe configuration method includes obtaining configuration information of a self-contained subframe of a current frequency band based on a subframe transmission direction of a neighboring frequency band. The self-contained subframe includes a downlink control (DLcontrol) field, a first transmission subframe, a second transmission subframe, a guard period (GP), and an uplink control (ULcontrol) field. The first transmission subframe or the second transmission subframe of the self-contained subframe is transmitted in the same subframe transmission direction used during subframe transmission on the neighboring frequency band. Alternatively, the first transmission subframe or the second transmission subframe of the self-contained subframe is transmitted in a guard period of the neighboring frequency band.
