<p>Disclosed are a downlink data transmission channel estimation method and device, the method comprising: receiving downlink data, the downlink data bearing a physical downlink shared channel (PDSCH), a reference signal for estimating a physical channel value, and a reference signal for estimating an equivalent channel value; and according to the reference signal for estimating the equivalent channel value, estimating the equivalent channel value of a resource block on the resource block bearing the PCSCH; and according to the reference signal for estimating the physical channel value, estimating the physical channel value of each carrier and the physical channel value of the resource block on the resource block bearing the PDSCH; determining a resource block pre-coding matrix according to the equivalent channel value and physical channel value of the resource block; and determining the equivalent channel value of each carrier according to the physical channel value of each carrier and the resource block pre-coding matrix. The present invention reduces impact of Doppler effect on channel estimation, thus improving the precision of downlink data transmission estimation.</p> |
