Reference signal transmission method, channel measurement method, radio base station and user terminal

A channel measurement method performed by a user terminal, including:

• receiving port indication information which indicates measurement ports for resource elements in a common reference signal resource region, wherein one resource element in the common reference signal resource region is allocated with measurement ports respectively corresponding to one or more channel measurement types;
• obtaining reference information transmitted by the resource elements in the common reference signal resource region, according to the port indication information;
• processing the reference information according to channel measurement types corresponding to the measurement ports indicated by the port indication information.

A radio base station including:

• a transmitting unit configured to transmit port indication information which indicates measurement ports for resource elements in a common reference signal resource region, wherein one resource element in the common reference signal resource region is allocated with measurement ports corresponding to one or more channel measurement types, and
• a processing unit configured to indicate the transmitting unit to transmit reference information to a user terminal by using the resource elements in the common reference signal resource region.

A user terminal including:

• a receiving unit configured to receive resource region indication information which indicates a common reference signal resource region, and to receive port indication information which indicates measurement ports for resource elements in the common reference signal resource region, wherein one resource element in the common reference signal resource region is allocated with measurement ports respectively corresponding to one or more channel measurement types;
• a processing unit configured to obtain, according to the resource region indication information and the port indication information, reference information transmitted by the resource elements in the common reference signal resource region, and to process the reference information according to channel measurement types corresponding to the measurement ports indicated by the port indication information.
