Claim of US Patent No. 10,542,561

1. A method for a user equipment to receive a downlink signal in a cellular communication system, the method comprising:monitoring a first common control channel indicating a downlink (DL) interval of subframe (SF) #(n?1) and SF #n;
monitoring a second common control channel indicating a DL interval of SF #n and SF #(n+1); and
performing a DL reception process in the SF #n based on a detection result of the first common control channel and a detection result of the second common control channel,
wherein only a detection process for a first physical channel/signal is allowed in the DL reception process in SF #n when a detection of the first common control channel fails, a detection of the second common control channel is successful, and the DL interval of SF #n indicated by the second common control channel is a part of a total orthogonal frequency division multiplexing (OFDM) symbols of SF #n,
wherein the first physical channel/signal comprises a Discovery Reference Signal (DRS),
wherein the DL interval represents occupied OFDM symbols in a DL subframe.
