DOWNLINK SIGNAL RECEPTION METHOD AND USER EQUIPMENT, AND DOWNLINK SIGNAL TRANSMISSION METHOD AND BASE STATION

WIPO Patent Application WO/2017/209547

A1

A user equipment attempts to decode decoding candidates and detects a physical downlink control channel (PDCCH) within time symbols from time symbol #0 to time symbol #N-1 for downlink control channel transmission in a transmission time interval (TTI). The user equipment receives downlink data on the basis of downlink control information carried by the PDCCH. Each of time symbol #0 to time symbol #N-1 includes a floor(X/N) number of decoding candidates. N is a maximum number of time symbols available for downlink control channel transmission in the TTI and is equal to or smaller than N, and X is a maximum number of decoding candidates for each TTI.
