METHOD, DEVICE AND USER EQUIPMENT FOR REDUCING COLLISION ON CONTROL CHANNELS

摘要

A method for reducing collision on control channels comprises: determining at least two iteration initial values on at least two carriers for a user equipment according to the user equipment identifier (UEID), wherein the user equipment (UE) corresponds to the UEID, the at least two carriers include the first carrier and the second carrier,  the at least two iteration initial values include the first iteration initial value and the second iteration initial value, the first carrier corresponds to the first iteration initial value, the second carrier corresponds to the second iteration initial value, and the first iteration initial value differs from the second iteration initial value; determining the starting position of the UE in the control channel search space on the first carrier according to the first iteration initial value, and determining the starting position of the UE in the control channel search space on the second carrier according to the second iteration initial value. A device for reducing collision on control channels is also disclosed and it can be achieved that when control channels of two or more UEs conflict on one carrier, the control channels of said two or more UEs will not conflict on at least one other carrier.
