Title:
TRANSMISSION PROCESSING METHOD AND DEVICE FOR ENHANCED PHYSICAL DOWNLINK CONTROL CHANNEL
Document Type and Number:
WIPO Patent Application WO/2016/095109
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a transmission processing method and device for an enhanced physical downlink control channel. The method comprises: after rate matching processing on N pieces of DCI and before layer mapping and precoding processing on the N pieces of DCI, mapping first DCI to an RE of a first symbol in a TTI, wherein N≥l, the N pieces of DCI are transmitted in the TTI, the first symbol is any symbol in the TTI, and the first DCI comprises at least one of the N pieces of DCI; and in the time of a current symbol, performing first processing on the RE of the first symbol, wherein the first processing comprises scrambling processing, modulation processing, power control processing, layer mapping and precoding processing, and processing in IFFT processing except second processing, the first symbol is any symbol, in the TH, following the current symbol, and the second processing is processing performed before the first DCI is mapped to the RE of the first symbol and after the rate matching processing. The technical problem of delay insufficiency in EPDCCH processing is solved.
