Problems solved by technology

For E-PDCCH, the SCID will be notified to the UE together with the E-PDCCH, so that the UE cannot know the SCID in advance, and cannot know the DMRS required to demodulate the E-PDCCH, and thus cannot demodulate the E-PDCCH

Abstract

The invention provides a demodulation pilot signal processing method, base station and user equipment. Among them, a processing method includes: the base station generates the DMRS corresponding to the E-PDCCH according to the information that the UE can know before receiving the E-PDCCH sent by the base station; when the base station maps the DMRS to the transmission pilot corresponding to the downlink control channel region sent to the UE on frequency resources. In the technical solution of the present invention, the base station and the UE no longer use the SCID to generate the DMRS, which solves the problem that the UE cannot obtain the SCID and cannot generate the DMRS before receiving the E-PDCCH, and thus cannot demodulate the E-PDCCH, and solves the problem that the E-PDCCH demodulation problem.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a demodulation pilot signal processing method base station and user equipment. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) communication system, the time-frequency resources in each downlink subframe are divided into two regions: the downlink control channel region and the downlink A data channel area; wherein, the downlink control channel area occupies the first N Orthogonal Frequency Division Multiplexing (OFDM) symbols, and N is less than or equal to 3; the downlink data channel area occupies the remaining OFDM symbols. The Physical Downlink Control Channel (PDCCH) is used to transmit scheduling instruction signaling for user uplink or downlink data transmission, such as data channel resource allocation, modulation and coding mode, multi-antenna transmission, hybrid automatic repeat request (Hybrid Automatic...
