Abstract
Provided are a demodulation pilot signal processing method a base station and user equipment. The processing method comprises: a base station generating a DMRS corresponding to an E PDCCH in accordance with information that can be learnt by UE before receiving the E PDCCH sent by the base station; the base station mapping the DMRS onto a time frequency resource of a transmission pilot frequency corresponding to a downlink control channel region and sending same to the UE. In the technical solution of the present invention the base station and the UE no longer use an SCID to generate a DMRS thereby solving the problem that the SCID cannot be obtained and the DMRS cannot be generated before the UE receives the E PDCCH and then the E PDCCH cannot be demodulated and solving the demodulation problem of the E PDCCH.
