Methods and apparatus for power allocation and/or rate selection for UL MIMO/SIMO operations with PAR considerations

A method of wireless communication, comprising:

• receiving a channel quality report of a channel, the channel quality report associated with a first modulation type and a corresponding first peak to average power ratio (PAR) back off value;
• determining a second modulation type of the channel based on the channel quality report and the first PAR backoff value;
• determining a second PAR backoff value associated with the second modulation type;
• and
• transmitting scheduling information to a UE, the scheduling information including the second modulation type associated with the second PAR back off value and a power allocation, the power allocation compensating for a difference between the first PAR backoff value and the second PAR backoff value based on a difference between the first modulation scheme and the second modulation scheme.

A computer program product for wireless communications stored on a non-transitory computer-readable medium and comprising program code for performing the steps of:

• receiving a channel quality report of a channel, the channel quality report associated with a first modulation type and a corresponding first peak to average power ratio (PAR) back off value;
• determining a second modulation type of the channel based on the channel quality report and the first PAR backoff value;
• determining a second PAR backoff value associated with the second modulation type;
• and
• transmitting scheduling information to a UE, the scheduling information including the second modulation type associated with the second PAR back off value and a power allocation, the power allocation compensating for a difference between the first PAR backoff value and the second PAR backoff value based on a difference between the first modulation scheme and the second modulation scheme.

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured for:
• reporting, by a user equipment (UE), channel quality information for a channel, the reporting associated with a first modulation scheme and a corresponding first peak to average power ratio (PAR) back off value;
• and
• receiving scheduling information by the UE in response to the reporting, the scheduling information including a second modulation type associated with a second PAR back off value and a power allocation for the channel, the power allocation compensating for a difference between the first PAR backoff value and the second PAR back off value based on a difference between the first modulation scheme and the second modulation scheme.
