5. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
at least one controller configured to:
transmit capability information including a first maximum number of multiple-input and multiple output (MIMO) layers of a first carrier and a second maximum number of MIMO layers of a second carrier uplink, wherein the first carrier is different from the second carrier,
receive a first radio resource control (RRC) message including configuration information for a normal uplink including a third maximum number of MIMO layers,
receive a second RRC message,
identify a fourth maximum number of MIMO layers for a supplementary uplink based on a configuration information for the supplementary uplink, in case that the first RRC message includes the configuration information for the supplementary uplink or the second RRC message includes the configuration information for the supplementary uplink, the configuration information for the supplementary uplink including the fourth maximum number of MIMO layers and information related to a bandwidth part (BWP) of the supplementary uplink, and
transmit data of a physical uplink shared channel (PUSCH) using one of the normal uplink and the supplementary uplink,
wherein the normal uplink is using the first carrier and the supplementary uplink is using the second carrier.
