Reference signal design for numerology ambiguity

A transmitter for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• identify a set of resource elements on which to transmit a reference signal based at least in part on a numerology being used by the transmitter and at least one of a maximum system numerology or a minimum system numerology, wherein the reference signal includes a number of repetitions of a same waveform, wherein the number of repetitions is based on 2(m−1), wherein m is equal to a number of possible system numerologies, wherein m is a natural number, wherein the maximum system numerology is a maximum numerology supported by a communication mode with which one or more of the transmitter or a receiver is operating, and wherein the minimum system numerology is a minimum numerology supported by the communication mode;
• and
• transmit the reference signal on the set of resource elements based at least in part on identifying the set of resource elements.

A receiver for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• identify a set of resource elements from which to obtain a reference signal based at least in part on a numerology being used by the receiver and at least one of a maximum system numerology or a minimum system numerology, wherein the reference signal includes a number of repetitions of a same waveform, wherein the number of repetitions is based on 2(m−1), wherein m is equal to a number of possible system numerologies, wherein m is a natural number, wherein the maximum system numerology is a maximum numerology supported by a communication mode with which one or more of a transmitter or the receiver is operating, and wherein the minimum system numerology is a minimum numerology supported by the communication mode;
• and
• obtain the reference signal from the set of resource elements based at least in part on identifying the set of resource elements.
