Reference signal design for wireless communications

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a reference signal transmitted according to a reference signal (RS) density scheme, the RS density scheme selected from a set of RS density schemes;
• identify the RS density scheme based at least in part on a type of a channel associated with the reference signal or a coverage enhancement for the channel associated with the reference signal;
• and
• communicate using the reference signal according to the RS density scheme.

An apparatus for wireless communication, comprising:

• means for receiving a reference signal transmitted according to a reference signal (RS) density scheme, the RS density scheme selected from a set of RS density schemes;
• means for identifying the RS density scheme based at least in part on a type of a channel associated with the reference signal or a coverage enhancement for the channel associated with the reference signal;
• and
• means for communicating using the reference signal according to the RS density scheme.

A non-transitory computer-readable medium storing computer-executable code for wireless communication, the code executable to:

• receive a reference signal transmitted according to a reference signal (RS) density scheme, the RS density scheme selected from a set of RS density schemes;
• identify the RS density scheme based at least in part on a type of a channel or a coverage enhancement for the channel;
• and
• communicate using the reference signal according to the RS density scheme.
