Determining an energy per resource element for a symbol including a cell-specific reference signal

A method of wireless communication performed by a base station (BS), comprising:

• determining, for an orthogonal frequency division (OFDM) symbol that includes one or more cell-specific reference signal (CRS) resource elements and one or more narrowband physical uplink shared channel (NPDSCH) resource elements, an NPDSCH energy per resource element (EPRE),
• wherein the NPDSCH EPRE for the OFDM symbol is based at least in part on an EPRE differential between a narrowband reference signal (NRS) EPRE and a CRS EPRE;
• and
• transmitting an indication of the NPDSCH EPRE to a user equipment (UE).

A user equipment (UE) 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:
• determine, for an orthogonal frequency division (OFDM) symbol that includes one or more cell-specific reference signal (CRS) resource elements and one or more narrowband physical downlink shared channel (NPDSCH) resource elements, an NPDSCH energy per resource element (EPRE),
• wherein the NPDSCH EPRE for the OFDM symbol is based at least in part on an EPRE differential between a narrowband reference signal (NRS) EPRE and a CRS EPRE;
• and
• demodulate the OFDM symbol based at least in part on the NPDSCH EPRE.
