Communication using multiple modulation coding schemes based on difference in time from demodulation reference signal communication

A user equipment (UE) comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to:
• determine a first suggested modulation coding scheme (MCS) for a base station (BS) to transmit data to the UE in one or more first time periods based on a first difference in time between the one or more first time periods and one or more time periods allocated for a demodulation reference signal (DMRS);
• determine a second suggested MCS for the BS to transmit data to the UE in one or more second time periods based on a second difference in time between the one or more second time periods and the one or more time periods allocated for the DMRS, the first suggested MCS indicating a higher data rate than the second suggested MCS based on the first difference being less than the second difference;
• transmit, to the BS, an indication of the first suggested MCS and the second suggested MCS;
• receive, from the BS, an indication of a first MCS and a second MCS determined by the BS based on the first suggested MCS and the second suggested MCS;
• receive, from the BS, data in the one or more first time periods using the first MCS;
• receive, from the BS, data in the one or more second time periods using the second MCS;
• and
• receive, from the BS, the DMRS in the one or more time periods allocated for the DMRS.

A method of wireless communication performed at a base station (BS), comprising:

• determining a first modulation coding scheme (MCS) for transmitting data in one or more first time periods based on a first difference in time between the one or more first time periods and one or more time periods allocated for transmitting a demodulation reference signal (DMRS);
• determining a second MCS for transmitting data in one or more second time periods based on a second difference in time between the one or more second time periods and the one or more time periods allocated for transmitting the DMRS, the first MCS indicating a higher data rate than the second MCS based on the first difference being less than the second difference;
• transmitting data to a user equipment (UE) in the one or more first time periods using the first MCS;
• transmitting data to the UE in the one or more second time periods using the second MCS;
• and
• transmitting the DMRS to the UE in the one or more time periods allocated for transmitting the DMRS.
