Phase rotation for in-band signal generation for narrow band transmission

An apparatus for wireless communication at a base station comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine a phase offset for a signal, the phase offset having a relationship to a reference point in time, wherein the reference point comprises a reference symbol and the relationship corresponds to an index relative to the reference symbol;
• and
• transmit the signal using the determined phase offset.

A method for wireless communications at a user equipment (UE), comprising:

• receiving a first signal associated with a first frequency range;
• and
• rotating a symbol associated with a second signal by a per symbol phase offset having a relationship to a reference point in time;
• wherein the reference point comprises a reference symbol in the second signal, the relationship corresponds to an index relative to the reference symbol, and the first frequency range is within a second frequency range associated with the second signal.

An apparatus for wireless communication at a User Equipment (UE), comprising:

• means for receiving a first signal associated with a first frequency range;
• and
• means for rotating a symbol associated with a second signal by a per symbol phase offset having a relationship to a reference point in time;
• wherein the reference point comprises a reference symbol in the second signal, the relationship corresponds to an index relative to the reference symbol, and the first frequency range is within a second frequency range associated with the second signal.
