Claim Text:
1. A method of measuring strength of an interference signal from a first eNode B measured by a user equipment in a CoMP (coordinated multipoint) environment, the method comprising: receiving a plurality of CSI-RSs (channel status information-reference signals) from a second eNode B using a first resource element (RE) pair and a second RE pair; receiving a downlink signal from the first eNode B using the first RE pair and the second RE pair; and measuring a plurality of interference strengths based on a plurality of the CSI-RSs and the received downlink signal, wherein the first RE pair is muted and the second RE pair is an allocated PDSCH (physical downlink shared channel) of the first eNode B when the first RE pair and the second RE pair are configured by an identical antenna port.
