Method and apparatus of transmitting uplink signal

A method for transmitting an uplink signal by a communication apparatus in a wireless communication system, the method comprising:

• multiplexing control information with a data block among a plurality of data blocks of the uplink signal;
• and
• transmitting the uplink signal to a base station,
• wherein a number of modulation symbols for the control information is determined by the following equation:

A communication apparatus configured to transmit an uplink signal in a wireless communication system, the communication apparatus comprising:

• a radio frequency (RF) unit;
• and
• a processor configured to multiplex control information in all layers with a plurality of data blocks of the uplink signal, and transmit the uplink signal to a base station through the RF unit,
• wherein a number of modulation symbols per layer for the control information is determined using a reciprocal of a sum of spectral efficiencies for respective data blocks of the plurality of data blocks, and
• wherein a spectral efficiency for a data block is obtained based on a ratio of a size of the data block to a number of resource elements (REs) for an initial physical uplink shared channel (PUSCH) transmission of the data block.
