发明名称 DEMODULATION REFERENCE SIGNAL PROCESSING METHOD, BASE STATION AND USER EQUIPMENT
摘要 The embodiments of the present invention provide a demodulation reference signal processing method, a base station and a user equipment. A processing method includes: generating, by a base station, a DMRS corresponding to an E-PDCCH by using information that is available before a UE receives the E-PDCCH sent by the base station; and mapping, by the base station, the DMRS onto a time-and-frequency resource corresponding to a downlink control channel region and used for transmitting a reference signal, and sending the DMRS to the UE. In the technical solutions of the embodiments of the present invention, the base station and the UE no longer use an SCID for generating the DMRS, which solves the problem that the UE cannot obtain the SCID before receiving the E-PDCCH and cannot generate the DMRS, and further, cannot demodulate the E-PDCCH, and enables demodulation of the E-PDCCH.

主权项 1. A demodulation reference signal (DMRS) processing method, comprising: generating, by a base station, a DMRS corresponding to an extended physical downlink control channel (E-PDCCH) according to information that is available before a user equipment (UE) receives the E-PDCCH sent by the base station; and mapping, by the base station, the DMRS onto a time-and-frequency resource corresponding to a downlink control channel region and used for transmitting a reference signal; and sending the DMRS to the UE.
