Method and apparatus for reduced capability terminal to perform random access using a plurality of PUCCH common configuration in mobile wireless communication system

1. A method performed by a terminal, the method comprising:

receiving in a first cell, by a terminal from a base station, System Information Block1 (SIB1), wherein the SIB1 includes a servingCellConfigCommon, and the servingCellConfigCommon includes a first uplink configuration information and a second uplink configuration information;

performing, by the terminal, random access procedure based on a timeAlignmnetTimer in the first uplink configuration information and a second pucch-ConfigCommon in the second uplink configuration information in response to presence of the second pucch-ConfigCommon in the SIB1; and

performing, by the terminal, random access procedure based on the timeAlignmnetTimer in the first uplink configuration information and a first pucch-ConfigCommon in the first uplink configuration information in response to absence of the second pucch-ConfigCommon in the SIB1,

wherein the first uplink configuration information includes the timeAlignmnetTimer and the first pucch-ConfigCommon, and the second uplink configuration information includes the second pucch-ConfigCommon,

wherein the second uplink configuration information includes an initial uplink BandWidth Part (BWP) for a type2 terminal,

wherein the terminal is the type2 terminal supporting a narrower bandwidth than a type1 terminal, and

wherein the second pucch-ConfigCommon is applied to the type2 terminal.

2. The method of claim 1 ,

wherein the first pucch-ConfigCommon includes a first pucch-ResourceCommon and the second pucch-ConfigCommon includes a second pucch-ResourceCommon.

3. The method of claim 1 ,

wherein the terminal performs PUCCH transmission during the random access procedure based on the second pucch-ResourceCommon in response to presence of the second pucch-ConfigCommon in the SIB1.

4. A terminal in a wireless communication system, the terminal comprising:

a transceiver configured to transmit and receive a signal; and

a controller configured to control the transceiver to:

receive in a first cell from a base station, a System Information Block1 (SIB1), wherein the SIB1 includes a servingCellConfigCommon, and the servingCellConfigCommon includes a first uplink configuration information and a second uplink configuration information;

perform random access procedure based on a timeAlignmnetTimer in the first uplink configuration information and a second pucch-ConfigCommon in the second uplink configuration information in response to presence of the second pucch-ConfigCommon in the SIB1; and

perform random access procedure based on the timeAlignmnetTimer in the first uplink configuration information and a first pucch-ConfigCommon in the first uplink configuration information in response to absence of the second pucch-ConfigCommon in the SIB1,

wherein the first uplink configuration information includes the timeAlignmnetTimer and the first pucch-ConfigCommon and the second uplink configuration information includes the second pucch-ConfigCommon,

wherein the second uplink configuration information includes an initial uplink BandWidth Part (BWP) for a type2 terminal,

wherein the terminal is the type2 terminal supporting a narrower bandwidth than a type1 terminal,

wherein the timeAlignmentTimer in the first uplink configuration information is applied to the type 1 terminal and the type2 terminal, and

wherein the second pucch-ConfigCommon is applied to the type2 terminal.

5. A method performed by a base station, the method comprising:

transmitting in a first cell, by a base station, a System Information Block1 (SIB1), wherein the SIB1 includes a servingCellConfigCommon, and the servingCellConfigCommon includes a first uplink configuration information and a second uplink configuration information;

performing in the first cell, by the base station with a first type terminal, random access procedure based at least in part on a timeAlignmnetTimer in the first uplink configuration information and a first pucch-ConfigCommon in the first uplink configuration information; and

performing in the first cell, by the base station with a second type terminal, random access procedure based at least in part on the timeAlignmnetTimer in the first uplink configuration information and a second pucch-ConfigCommon in the second uplink configuration information,

wherein the first uplink configuration information includes the timeAlignmnetTimer and the first pucch-ConfigCommon and the second uplink configuration information includes the second pucch-ConfigCommon,

wherein the timeAlignmentTimer in the first uplink configuration information is applied to the first type terminal and the second type terminal, and

wherein the second pucch-ConfigCommon is applied to the second type terminal.
