說明書
According to another aspect, a wireless communication device for controlling uplink transmission power for Coordinate Multi-Point (CoMP) transmission of a first node and a second node on a first component carrier at a first frequency, the device comprises: circuitry configured to receive a downlink signal from the second node on a second component carrier at a second frequency different from the first frequency, determine a first downlink path loss associated with receipt of the downlink signal from the second node on the second component carrier at the second frequency, estimate a second downlink path loss associated with the second node performing the CoMP transmission on the first component carrier at the first frequency based on the determined first downlink path loss, and estimate a first uplink path loss of a first uplink signal output from the device to the second node on the first component carrier at the first frequency based on the estimated second downlink path loss, to compensate uplink signal transmission power for the CoMP transmission. The uplink signal may be one of a Physical Uplink Control Channel (PUCCH) signal, Physical Uplink Shared Channel (PUSCH) signal, and a Sounding Reference Signal (SRS).
