First Claim
1. A method of transition between distributed transmission mode and localized transmission mode includes:
- a) transmitting, by a Base Station (BS), a measurement control message to a User Equipment (UE);
b) performing by the UE, a corresponding measurement and transmits a required measurement report message to the BS;
c) transmitting, by the BS, a transition indicator message of a new mode to the UE based on the measurement report message sent from the UE;

Abstract
Provided is a method for transitioning between a distributed transmission mode and a localized transmission mode, including transmitting, by a Base Station (BS), a measurement control message to a User Element (UE), wherein the UE makes corresponding measurement and transmits a required measurement report message to the BS and the BS transmits a transition indicator message of new mode to the UE based on measurement report message sent from the UE; and commencing CQI reporting and a downlink transmission of a new mode between the UE and the BS. The BS can choose a more appropriate transmission mode for the downlink transmission based on changing characteristics of the channel in the time domain and the frequency domain.
