1. A method performed by a User Equipment (UE), the method comprising:
receiving downlink control information indicating a Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) delay value associated with a Hybrid Automatic Repeat reQuest (HARQ) process in Long-Term Evolution Machine Type Communication (LTE-MTC); and
transmitting a Physical Uplink Control Channel (PUCCH) including HARQ-ACK or Hybrid Automatic Repeat reQuest Negative Acknowledgement (HARQ-NACK) with a delay in accordance with the HARQ-ACK delay value,
wherein the HARQ-ACK delay value is:
a number N of Bandwidth Reduced Low Complexity/Coverage Enhancement (BL/CE) Downlink (DL) subframes+1 subframe+a number M of BL/CE Uplink (UL) subframes.
