Abstract
In order to save radio resources, the present invention provides a method for improving a multi-input multi-output, known as MIMO, procedure for a network of a wireless communications system. The method includes the following steps. Only two parameter values are used in a MIMO operation information element, also called IE, of a MIMO parameter IE, to indicate a user equipment, called UE hereinafter, to start or continue MIMO operation. The UE is indicated to stop the MIMO operation when the MIMO parameter IE is not included in an ACTIVE SET UPDATE, CELL UPDATE CONFIRM, or any reconfiguration message sent to the UE.
