Patent ID: 8208855

Claim:
A method of transitioning between a distributed transmission mode and a localized transmission mode, the method comprising the steps of: transmitting, by a Base Station (BS), a measurement control message to a User Equipment (UE); performing, by the UE, a measurement corresponding to the measurement control message; transmitting a measurement report message based on the measurement to the BS; 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; and performing Channel Quality Indicator (CQI) reporting and a downlink transmission of the new mode between the UE and the BS begins, wherein the new mode includes one of the distributed transmission mode and the localized transmission mode, and wherein the measurement report message includes a value indicating downlink channel fading selectivity in a frequency domain, which satisfies a threshold indicated by the BS to the UE.
