Abstract

Systems and methods for measurement reporting in unlicensed spectrum are disclosed. A user device may perform one or more signaling measurements in an unlicensed frequency band in accordance with a first Radio Access Technology (RAT) and send feedback information relating to the signaling measurements to a small cell base station, with the feedback information being sent in accordance with a second RAT. A message may be sent to the user device in accordance with the second RAT that configures the user device to perform the one or more signaling measurements in the unlicensed frequency band.

7. The method of claim 1, further comprising receiving a message from the small cell base station in accordance with the second RAT that configures the user device to perform the one or more signaling measurements in the unlicensed frequency band in accordance with the first RAT.

8. The method of claim 7, wherein the message is a User Datagram Protocol (UDP) message.

9. An apparatus for measurement reporting in a wireless communication environment, comprising:

a first transceiver configured to perform at a user device one or more signaling measurements in an unlicensed frequency band in accordance with a first Radio Access Technology (RAT); and

a second transceiver configured to send feedback information relating to the signaling measurements to a small cell base station, the feedback information being sent in accordance with a second RAT.
