Abstract
Embodiments provide a method and a device for using an unlicensed spectrum. In the method, a first access device receives first indication information sent by a second access device, where the first indication information is used to indicate idle time, in which the second access device does not perform data transmission, in a time segment that is reserved for the second access device to perform, by using an unlicensed spectrum, data transmission, and the first access device performs data transmission in the idle time by using the unlicensed spectrum. In a device provided, a first access device includes a receiving unit and a transmission unit.
Claims16
A first access device, comprising a processor, a receiver, and a transmitter connected to the receiver by a bus;
- wherein the receiver is configured to receive first indication information from a second access device, wherein the first indication information indicates an idle time in which the second access device does not perform data transmission, the idle time being comprised in a time segment that is reserved for the second access device to perform data transmission using an unlicensed spectrum;
- and
- the processor is configured to control the transmitter or the receiver to perform data transmission in the idle time using the unlicensed spectrum.
A second access device, comprising a processor and a transmitter coupled to the processor by a bus;
- wherein the processor is configured to acquire an idle time in which the second access device does not perform data transmission, the idle time being comprised in a time segment that is reserved for the second access device to perform data transmission using an unlicensed spectrum;
- and
- a transmitter, configured to send the idle time to a first access device, wherein the idle time is used as a time segment in which the first access device performs data transmission using the unlicensed spectrum.
A method for using an unlicensed spectrum, comprising:
- receiving, by a first access device, first indication information sent by a second access device, wherein the first indication information indicates an idle time in which the second access device does not perform data transmission, in a time segment that is reserved for the second access device to perform data transmission using an unlicensed spectrum;
- and
- performing, by the first access device, data transmission in the idle time using the unlicensed spectrum.
