Method for operating IoT in cellular system and system therefor

A base station in a cellular system, the base station comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver and configured to:
• generate a master information block (MIB) including operation mode information indicating an operation mode, among a plurality of operation modes for narrow band internet of things (IoT) communication, and
• control the transceiver to transmit the MIB to a user equipment (UE),
• wherein the plurality of operation modes include a first in-band mode indicating that the cellular system and a narrow band IoT system share a same cell identifier (ID), a second in-band mode indicating that the cellular system and the narrow band IoT system have a different cell ID, a guard-band mode indicating a guard-band deployment, and a standalone mode indicating a standalone deployment.

A method of a user equipment (UE) in a cellular system, the method comprising:

• receiving, by the UE, a master information block (MIB) from a base station;
• and
• identifying, by the UE, operation mode information included in the MIB,
• wherein the operation mode information indicates an operation mode, among a plurality of operation modes for narrow band internet of things (IoT) communication, and
• wherein the plurality of operation modes include a first in-band mode indicating that the cellular system and a narrow band IoT system share a same cell identifier (ID), a second in-band mode indicating that the cellular system and the narrow band IoT system have a different cell ID, a guard-band mode indicating a guard-band deployment, and a standalone mode indicating a standalone deployment.

A user equipment (UE) in a cellular system, the UE comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver and configured to:
• control the transceiver to receive a master information block (MIB) from a base station, and
• identify operation mode information included in the MIB,
• wherein the operation mode information indicates an operation mode, among a plurality of operation modes for narrow band internet of things (IoT) communication, and
• wherein the plurality of operation modes include a first in-band mode indicating that the cellular system and a narrow band IoT system share a same cell identifier (ID), a second in-band mode indicating that the cellular system and the narrow band IoT system have a different cell ID, a guard-band mode indicating a guard-band deployment, and a standalone mode indicating a standalone deployment.
