Method for measuring channel state information, ue and base station

User equipment configured with coordinated multi-point mode in a Macro cell, comprising:

• a first receiving unit, configured to receive in a subframe of Pico cell the channel state information reference symbol or common reference symbol of the Pico cell, the subframe of Pico cell corresponding to the almost blank subframe in a measurement set;
• and
• a first measuring unit, configured to measure the channel state information of the Pico cell based on the channel state information reference symbol or common reference symbol of the Pico cell.

A method for measuring channel state information, which is applied for user equipment configured with coordinated multi-point mode in a Pico cell, the method comprising:

• receiving in a subframe of Macro cell, by the user equipment, the channel state information reference symbol or common reference symbol of the Macro cell, the subframe of Macro cell corresponding to the muted subframe of Pico cell in a measurement set;
• and
• measuring the channel state information of the Macro cell based on the channel state information reference symbol or common reference symbol of the Macro cell.

User equipment configured with coordinated multi-point mode in a Pico cell, comprising:

• a second receiving unit, configured to receive in a subframe of Macro cell the channel state information reference symbol or common reference symbol of the Macro cell, the subframe of Macro cell corresponding to the muted subframe of Pico cell in a measurement set;
• and
• a second measuring unit, configured to measure the channel state information of the Macro cell based on the channel state information reference symbol or common reference symbol of the Macro cell.

A method for measuring channel state information, which is applied for range expansion user equipment configured with coordinated multi-point mode in a Pico cell, the method comprising:

• receiving in a subframe of Pico cell of a measurement set, by the user equipment, the channel state information reference symbol or common reference symbol of the Pico cell, the subframe of Pico cell corresponding to the almost blank subframe of a Macro cell;
• and
• measuring the channel state information of the Pico cell base on the channel state information reference symbol or common reference symbol of the Pico cell.

Range expansion user equipment configured with coordinated multi-point mode in a Pico cell, comprising:

• a third receiving unit, configured to receive in a subframe of Pico cell of a measurement set the channel state information reference symbol or common reference symbol of the Pico cell, the subframe of Pico cell corresponding to an almost blank subframe of a Macro cell;
• and
• a third measuring unit, configured to measure the channel state information of the Pico cell base on the channel state information reference symbol or common reference symbol of the Pico cell.

A method for measuring channel state information, which is applied for a base station, the method comprising:

• configuring, by the base station, a measurement set for user equipment belonging to the base station;
• and
• transmitting the measurement set to the user equipment by using upper layer radio resource control signalling.

A base station, comprising:

• a fourth configuring unit, configured to configure a measurement set for the user equipment;
• and
• a first transmitting unit, configured for transmitting the measurement set to the user equipment by using upper layer radio resource control signalling.
