Title:
DOWNLINK CHANNEL RECEIVING METHOD, AND TERMINAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/213951
Kind Code:
A1
Abstract:
The present application discloses a downlink channel receiving method and a terminal apparatus. The method comprises: a terminal apparatus receiving first downlink grant information and second downlink grant information sent by a network apparatus, the first downlink grant information instructing the terminal apparatus to receive a first physical downlink shared channel (PDSCH) on a first time unit, the second downlink grant information instructing the terminal apparatus to receive a second PDSCH on a second time unit, the first time unit and the second time unit having at least one overlapping symbol in a time domain, and the terminal apparatus being in an idle state; and the terminal apparatus determining, according to RNTIs used for scrambling the first downlink grant information and the second downlink grant information, which of the first PDSCH and the second PDSCH has decoding priority. Thus, the invention effectively decodes downlink data channels when transmission time units of the downlink data channels corresponding to downlink control channels using different RNTIs for scrambling have at least one overlapping symbol in the time domain, thereby improving the reception performance of the downlink data channels.
