摘要： Disclosed is a method for transmitting MBSFN subframe configuration information of neighboring cells in a wireless system, the method comprises steps of: transmitting, by a base station of a serving cell, MBSFN subframe configuration information of the serving cell to a UE which accepts services from the serving cell via a broadcast control channel (BCCH); transmitting, by the base station of the serving cell, information on a subset relationship of MBSFN subframe configurations of the neighboring cells relative to the MBSFN subframe configuration of the serving cell to the UE which accepts services from the serving cell via the broadcast control channel (BCCH); performing, by the UE, measurements on the neighboring cells according to the subframe configuration information of the serving cell and the information on the subset relationship of the MBSFN subframe configurations of the neighboring cells relative to the MBSFN subframe configuration of the serving cell. With the method of the present invention, the UE can learn about the MBSFN subframe configuration information of the neighboring cells in a more accurately manner. Therefore, more subframes can be measured to improve measurement precision. Meanwhile, the present invention is based on redefinition of messages in the existing method, and thus no extra signaling overhead will be introduced.

摘要： 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.
