Method and apparatus for configuring demodulation reference signal position in wireless cellular communication system

A method by a terminal in a wireless communication system, the method comprising:

• receiving, on a physical broadcast channel (PBCH), a master information block (MIB) including information for a position of a first demodulation reference signal (DMRS) for a first mapping type;
• identifying a mapping type from the first mapping type and a second mapping type;
• in case that the mapping type is the first mapping type, receiving a first DMRS on one symbol of a third symbol or a fourth symbol of a slot in a downlink, based on the MIB;
• and
• in case that the mapping type is the second mapping type, receiving a first DMRS on a first symbol of a scheduled downlink data resource.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• at least one processor configured to:
• control the transceiver to transmit, on a physical broadcast channel (PBCH), a master information block (MIB) including information for a position of a first demodulation reference signal (DMRS) for a first mapping type,
• identify a mapping type from the first mapping type and a second mapping type,
• in case that the identified mapping type is the first mapping type, control the transceiver to transmit the first DMRS on one symbol of a third symbol or a fourth symbol of a slot in a downlink, based on the MIB, and
• in case that the identified mapping type is the second mapping type, control the transceiver to transmit the first DMRS on a first symbol of a scheduled downlink data resource.
