Wireless communication devices have become smaller and more powerful in order to meet consumer needs and to improve portability and convenience. Consumers have become dependent upon wireless communication devices and have come to expect reliable service, expanded areas of coverage and increased functionality. A wireless communication system may provide communication for a number of wireless communication devices, each of which may be serviced by a base station. A base station may be a device that communicates with wireless communication devices.
As wireless communication devices have advanced, improvements in communication capacity, speed, flexibility and/or efficiency have been sought. However, improving communication capacity, speed, flexibility and/or efficiency may present certain problems.
For example, a wireless communication device transmitting in unlicensed spectrum may interfere with other wireless devices. To avoid transmission conflicts in unlicensed spectrum, wireless communication devices may wait until a channel is idle before transmitting. However, wireless communication devices operating in a Long-Term Evolution (LTE) communication system may transmit nearly continuously. Therefore, LTE devices may interfere with other wireless communication devices operating in unlicensed spectrum. As illustrated by this discussion, systems and methods that reduce interference may be beneficial.
