Abstract
Disclosed a method and an apparatus for configuring and transmitting a pilot, the method includes: a UE determines, according to a partitioned resource set, a parameter for generating an initial value of a demodulation pilot sequence; generates an initial value of the demodulation pilot sequence on the first resource set according to the first parameter, and generates an initial value on the second resource set according to the second parameter; and obtains the demodulation pilot sequence according to the initial value. In embodiments of the present invention, since parameters for calculating the initial value of the demodulation pilot sequence are respectively configured according to a pre-partitioned resource set, the initial value can be calculated according to the resource set to which the E-PDCCH belongs and the set parameter, thus obtaining the demodulation pilot sequence for demodulating the E-PDCCH, so as to improve demodulation performance of the E-PDCCH.
