1. A method performed by a base station of a wireless telecommunication system, the method comprising:
- detecting, by the base station, a demand for wireless radio resources;
requesting, by the base station, a user equipment (UE) to perform a scan for wireless channels in response to detecting the demand, wherein requesting the UE to perform the scan for wireless channels comprises the base station requesting the UE to perform the scan in response to detecting an increase in demand for wireless radio resources over a licensed band;
receiving, by the base station in response to the requesting, a measurement report from the UE;
selecting, by the base station after receipt of the measurement report, a wireless channel based on feedback information obtained from the measurement report, the feedback information corresponding to wireless channels within a vicinity of the UE; and
transmitting, by the base station after the selecting, at least one of a synchronization channel and a broadcast channel via the selected wireless channel.

9. A base station, comprising:
-
at least one memory device; and a processor configured to execute instructions stored on the at least one memory device such that when executed, cause the base station to; detect a demand for wireless radio resources; request a user equipment (UE) to perform a scan for wireless channels in response to detecting the demand, wherein requesting the UE to perform the scan for wireless channels comprises the base station requesting the UE to perform the scan in response to detecting an increase in demand for wireless radio resources over a licensed band; receive, in response to the request, a measurement report from the UE; select, after receipt of the measurement report, a wireless channel based on feedback information obtained from the measurement report, the feedback information corresponding to wireless channels within a vicinity of the UE; and transmit, after the selecting, at least one of a synchronization channel and a broadcast channel via the selected wireless channel. - View Dependent Claims (10, 11, 12, 13, 14)

15. A non-transitory computer medium storing instructions executable by a processor of a base station such that when executed, cause the base station to perform a method, the method comprising:
-
detecting, by the base station, a demand for wireless radio resources; requesting, by the base station, a user equipment (UE) to perform a scan for wireless channels in response to detecting the demand, wherein requesting the UE to perform the scan for wireless channels comprises the base station requesting the UE to perform the scan in response to detecting an increase in demand for wireless radio resources over a licensed band; receiving, by the base station in response to the requesting, a measurement report from the UE; selecting, by the base station after receipt of the measurement report, a wireless channel based on feedback information obtained from the measurement report, the feedback information corresponding to wireless channels within a vicinity of the UE; and transmitting, by the base station after the selecting, at least one of a synchronization channel and a broadcast channel via the selected wireless channel. - View Dependent Claims (16, 17, 18, 19, 20)
