Method and apparatus for configuring position of frequency resource

A first device, comprising:

• an acquiring unit, configured to acquire synchronization information of a second device;
• a determining and adjustment unit, configured to determine a synchronization status between the first device and the second device according to the synchronization information of the second device, and adjust a synchronization relationship between the first device and the second device, and set a synchronization status of the first device;
• a configuration unit, configured to configure a frequency resource close to an edge of a frequency band according to the synchronization information of the second device that is output by a determining and a adjustment unit, wherein the frequency resource is used to transmit data;
• a transmission scheduling unit, configured to schedule and use the configured frequency resource to transmit data;
• a first sending unit, configured to notify first user equipment that a transmission frequency resource of the first device changes;
• a receiving unit, configured to receive feedback information of the first user equipment, wherein the feedback information is a fed-back receiving capability of the first user equipment;
• and
• a second sending unit, configured to:
• when the first device is not synchronous with the second device, notify the second device that the first device is not in time synchronization with the second device, and the first device has configured a frequency resource close to an edge of a frequency band, wherein the frequency resource is used to transmit data.

A first device, comprising:

• at least one processor, a memory configured to store program code, a communications interface, and a bus, wherein the at least one processor, the memory, and the communications interface are connected to and communicate with each other by using the bus;
• and
• wherein the processor is configured to invoke the program code in the memory to:
• acquire synchronization information of a second device by using at least one communications interface,
• configure a frequency resource close to an edge of a frequency band according to the synchronization information of the second device, wherein the frequency resource is used to transmit data,
• schedule and use the communications interface, and schedule and use the configured frequency resource to transmit data,
• notify, by using the at least one communications interface, first user equipment that a transmission frequency resource of the first device changes,
• receive feedback information of the first user equipment by using the at least one communications interface, wherein the feedback information is a fed-back receiving capability of the first user equipment, and
• when the first device is not synchronous with the second device, notify, by using the at least one communications interface, the second device that the first device is not in time synchronization with the second device, and the first device has configured a frequency resource close to an edge of a frequency band, wherein the frequency resource is used to transmit data.

A second device, comprising:

• at least one processor, a memory configured to store program code, a communications interface, and a bus, wherein the at least one processor, the memory, and the communications interface are connected to and communicate with each other by using the bus;
• and
• wherein the processor is configured to invoke the program code in the memory to:
• notify, by using at least one communications interface, a first device that the second device has a capability of configuring, according to a frequency resource configured by the first device, a frequency resource used to transmit data by the second device,
• receive a notification from the first device by using the at least one communications interface, wherein when the first device is not synchronous with the second device, the first device notifies the second device that the first device is not in time synchronization with the second device, and the first device has configured a frequency resource close to an edge of a frequency band, wherein the frequency resource is used to transmit data, and
• after the notification of the first device is received, configure a frequency resource used to transmit data.

First user equipment, comprising:

• at least one processor, a memory configured to store program code, a communications interface, and a bus, wherein the at least one processor, the memory, and the communications interface are connected to and communicate with each other by using the bus;
• and
• wherein the processor is configured to invoke the program code in the memory to:
• receive a notification from a first device by using at least one communications interface, wherein the notification notifies the first user equipment that a transmission frequency resource of the first device changes, and
• after the notification, notify that a transmission frequency resource of the first device changes is received, needing to feed back a transmission capability of the first user equipment to the first device by using the at least one communications interface.
