Selection of modulation and coding schemes for control information multiplexed with data

An apparatus for wireless communication by a user equipment (UE), the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determining a spectral efficiency associated with transmission of data based on a number of information bits associated with control information, a number of resource elements to be used for the transmission of the data multiplexed with the control information, and a modulation order associated with the transmission;
• determine a first modulation and coding scheme (MCS) for control information on a sidelink channel based on the spectral efficiency associated with transmission of data on the sidelink channel and an offset β, wherein the offset β is used to determine a number of modulated symbols used for transmission of the control information when control information is multiplexed with data, wherein a modulation order associated with the first MCS is fixed to quadrature-phase shift keying (QPSK);
• and
• transmit, on the sidelink channel, the control information with the first MCS, the control information being multiplexed with data.
