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).

Abstract: A UE is configured to enable multiplexing of uplink transmissions of different priorities. When a first uplink channel for transmission of first HARQ-ACK information overlaps with a second uplink channel for transmission of second HARQ-ACK information, the UE may drop transmission of the first HARQ-ACK information and transmit the second HARQ-ACK information, based on the second HARQ-ACK information being a HARQ process-based HARQ-ACK codebook.
