Abstract: 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.

Abstract: One disclosure of the present application provides a method for a narrowband (NB) wireless device to determine whether or not to transmit a scheduling request (SR). The method may comprise a step of determining whether or not to transmit an SR by using a resource for the transmission of a hybrid automatic retransmit request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal. The step of determination may be performed if one or more HARQ processes are run. The resource for the HARQ ACK/NACK signal may include a narrowband physical uplink shared channel (NPUSCH).
