摘要： A method of performing a feedback for a multicast and broadcast service (MBS) is disclosed. A Multicast Broadcast Service (MBS) feedback method includes, generating, by a base station contained in a multi-cell multicast broadcast single frequency network (MBSFN) zone, a ranging channel code for a multicast broadcast service (MBS) feedback, allocating the ranging channel code to a mobile station contained in a cell zone of the base station, and receiving the MBS feedback information based on the ranging channel code from the mobile station. So, an adaptive modulation and coding (AMC) is applied to the MBS according to the NACK feedback, such that a throughput of the MBS system increases.

摘要： Disclosed is a method for transmitting a CoMP reference signal for accurate channel estimation. The CoMP reference signal is a cell-specific reference signal or a CoMP-zone-specific reference signal. A method for transmitting the cell-specific reference signal uses a CoMP set ID or does not apply a frequency shift value, or uses a serving cell ID or a frequency shift value of the serving cell. The cell-specific reference signal is transmitted using a preset resource region. A method for transmitting the CoMP-zone-specific reference signal is configured such that the pattern of the sequence of CoMP reference signals varies in each of the CoMP zones, and the pattern can be set in advance. The reference signal is multiplexed using an orthogonal code and transmitted to plural terminals using the same CoMP zone.
