Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 5:
6. A data transmission method, comprising:
sending resource configuration information to a terminal device, the resource configuration information being configured to indicate multiple resource sub-bands for transmitting data in a scheduling unit, each of the multiple resource sub-bands being formed by continuous physical resource blocks in a frequency domain,
wherein the resource configuration information comprises first position indication information, and the first position indication information is configured to indicate a starting physical resource block of a first resource sub-band in the frequency domain and a number of the physical resource blocks in the first resource sub-band, or the first position indication information is configured to indicate the starting physical resource block of the first resource sub-band in the frequency domain and an ending physical resource block of the first resource sub-band in the frequency domain; and
communicating the data with the terminal device on the multiple resource sub-bands according to the resource configuration information,
wherein the first position indication information is further configured to indicate a starting frequency-domain reference physical resource block and position of the starting physical resource block in the starting frequency-domain reference physical resource block, wherein the starting frequency-domain reference physical resource block is a frequency-domain reference physical resource block including the starting physical resource block in the frequency domain, and the starting physical resource block of the first resource sub-band in the frequency domain is determined based on an offset in the starting frequency-domain reference physical resource block.
