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.

1-12. (canceled)
A terminal device, comprising:
- a receiver configured to receive control signaling from a network device, the control signaling indicating a mapping mode to be used by the terminal device to map to-be-sent data to a transmission resource, the mapping mode comprising that a minimum unit for mapping the to-be-sent data is a resource element block and a frequency hopping pattern in a transmission process after the to-be-sent data is mapped to the transmission resource, and a length of the resource element block in time domain being less than a length of a physical resource block in the time domain;
- and
- a processor coupled to the receiver and configured to map the to-be-sent data to the transmission resource based on an indication of the control signaling using the resource element block as a unit.
A network device, comprising:
- a transmitter configured to send control signaling to a terminal device, the control signaling indicating a mapping mode to be used by the terminal device to map to-be-sent data to a transmission resource, the mapping mode comprising that a minimum unit for mapping the to-be-sent data is a resource element block and a frequency hopping pattern in a transmission process after the to-be-sent data is mapped to the transmission resource, and a length of the resource element block in time domain is being less than a length of a physical resource block in the time domain;
- and
- a processor coupled to the transmitter and configured to receive, based on an indication of the control signaling and using the resource element block as a unit, the to-be-sent data mapped to the transmission resource.
A computer program product comprising a non-transitory computer readable storage medium storing program code thereon for transmission resource mapping, the program code comprising instructions for executing a method that comprises:
- receiving control signaling from a network device, the control signaling indicating a mapping mode to be used by the terminal device to map to-be-sent data to a transmission resource, the mapping mode comprising that a minimum unit for mapping the to-be-sent data is a resource element block and a frequency hopping pattern in a transmission process after the to-be-sent data is mapped to the transmission resource, and a length of the resource element block in time domain being less than a length of a physical resource block in the time domain;
- and
- mapping the to-be-sent data to the transmission resource based on an indication of the control signaling using the resource element block as a unit.
