Claim 0:
1. A data transmission apparatus, comprising:
a transceiver configured to send scheduling information to a second device in a first frequency band, wherein
the scheduling information is configured for scheduling the second device to perform data transmission in a second frequency band,
the scheduling information carries first indication information indicating a resource used by the data transmission apparatus and the second device for performing the data transmission,
the data transmission apparatus is configured to send the scheduling information to the second device in a unicast manner, or send the scheduling information to a plurality of second devices, including the second device, in a broadcast manner, and
a format of the scheduling information is different based on whether the scheduling information is sent in the unicast manner or the broadcast manner; and

a processor operatively coupled to the transceiver, wherein the processor is configured to: based on the scheduling information, control the transceiver to perform the data transmission with the second device in the second frequency band by using the resource.
