Reference signal schemes in wireless communications

A method for wireless communication, comprising:

• configuring a first set of wireless resources for synchronization signal transmissions and a second set of wireless resources for broadcast channel transmissions, the second set of wireless resources comprising a first subset of time resources and a second subset of time resources;
• configuring locations of reference signal resources within the first subset of time resources and the second subset of time resources;
• determining a waveform of a reference signal transmission based at least in part on the locations of the reference signal resources;
• transmitting the reference signal over the reference signal resources.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• identify a first set of wireless resources for synchronization signal transmissions and a second set of wireless resources for broadcast channel transmissions, the second set of wireless resources comprising a first subset of time resources and a second subset of time resources;
• identify locations of reference signal resources within the first subset of time resources and the second subset of time resources;
• receive reference signal transmissions over the reference signal resources;
• determine a waveform of the reference signal transmissions based at least in part on the locations of the reference signal resources;
• and
• perform a channel estimation based at least in part on the received reference signal transmissions and the determined waveform of the reference signal transmissions.
