Title:

METHOD AND DEVICE FOR MAPPING CONTROL CHANNEL

Document Type and Number:

WIPO Patent Application WO/2010/145530

Kind Code:

A1

Abstract:

A method for mapping a control channel includes: a search space corresponding to each object is determined for the same aggregation level (101), wherein, the number of the objects is more than one, and the object is determined according to member carriers; and the control channel corresponding to the object is mapped into the determined search space (102). A method for detecting includes: initial position of the search space corresponding to the object is determined (201), wherein the number of the search spaces is more than one for the same aggregation level, and the object is determined according to member carriers; the size of the search space corresponding to the object is determined (202); and in the determined search space, the control channel is detected (203). A user device and a network device are also provided. Through the solution, the conflict of control channels is reduced, and the collision probability of control channels is reduced.
