METHOD OF SPECTRUM DETECTION AND DESIGN OF DETECTION FRAME STRUCTURE IN COMMUNICATION SYSTEM

摘要

The invention provides a method of spectrum detection in a user equipment of a communication system, the method including: for each detection period, detecting a signal from a target system in a specific downlink detection sub-frame of each frame in a detection duration; and sending a detection result to a base station at the end of the detection duration. The specific downlink detection sub-frame is a sub-frame #4 or #9 in a downlink/uplink sub-frame configuration 1; a sub-frame #4 or #9 in a configuration 2; a sub-frame #7 in a configuration 3; a sub-frame #4 or #7 in a configuration 4; and a sub-frame #3, #4, #7 or #9 in a configuration 5 of a TDD system. The specific downlink detection sub-frame is any other downlink sub-frame than sub-frames #0 and #5 in an FDD system. There is further provided a method of spectrum detection in a base station of a communication system, the method including: receiving detection result(s) from one or more user equipments; and determining whether one or more frequency bands of a target system are available according to the detection result(s).
