ADAPTIVELY USING SUBFRAMES FOR RADAR DETECTION IN UNLICENSED SPECTRUM
First Claim
1. A method of communications, comprising:
- scheduling a first set of subframes in a frame duration for traffic based at least in part on a first configuration for communications in an unlicensed frequency band;
scheduling, based at least in part on the first configuration, a second set of subframes in the frame duration for detection of a primary user of the unlicensed frequency band; and
adjusting a number of subframes in the first and second set of subframes based on a second configuration for communications, wherein the second configuration for communications is identified based on a type of primary user being detected.

Abstract
Systems and methods for adaptively using subframes for radar detection in unlicensed spectrum are disclosed. The systems and methods include scheduling a first set of subframes in a frame duration for traffic based at least in part on a first configuration for communications in an unlicensed frequency band. Further, the systems and methods include scheduling, based at least in part on the first configuration, a second set of subframes in the frame duration for detection of a primary user of the unlicensed frequency band. Moreover, the systems and methods include adjusting a number of subframes in the first and second set of subframes based on a second configuration for communications, wherein the second configuration for communications is identified based on a type of primary user being detected.
