Reference frequency for UI signal bar display

An apparatus, comprising:

• a memory;
• and
• one or more processors in communication with the memory;
• wherein the one or more processors are configured to:
• receive, via a system information block (SIB), an indication of a reference frequency from a serving cell, wherein the indication is a flag included in a system information block (SIB);
• measure reference signal received power (RSRP) for the serving cell and the reference frequency;
• determine a maximum RSRP based on the greater of the serving cell RSRP and reference frequency RSRP;
• and
• determine a number of signal bars based on the maximum RSRP.

A non-transitory computer readable memory medium storing program instructions executable by processing circuitry to cause a user equipment device (UE) to:

• receive, from a serving cell, an indication of a reference frequency;
• measure reference signal received power (RSRP) for the serving cell and the reference frequency;
• determine a maximum RSRP based on the greater of the serving cell RSRP and reference frequency RSRP;
• and
• determine a number of signal bars based on the maximum RSRP.
