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, wherein the first set of subframes in the first configuration comprises two sets of two consecutive subframes corresponding to downlink traffic periods; 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, wherein the second set of subframes in the first configuration comprises two sets of three consecutive subframes corresponding to gap periods for detection of the primary user of the unlicensed frequency band; comparing an amount of traffic to a scheduler threshold; identifying a second configuration for communications in the unlicensed frequency band when the amount of traffic exceeds the scheduler threshold, wherein the second configuration for communications is identified based on a type of primary user being detected; and adjusting a number of subframes in the first and second set of subframes based on the second configuration for communications.
