7.4.6 Hand-held hands-free UE receiving

26.1313GPPRelease 18RequirementsTerminal acoustic characteristics for telephonyTS

The receiving sensitivity frequency response from the SS audio input (analogue or digital input of the reference speech encoder of the SS) to the free-field shall be as follows:

The receiving sensitivity frequency response shall be within the mask which can be drawn with straight lines between the breaking points in table 29 on a logarithmic (frequency) – linear (dB sensitivity) scale.

It is recommended as a performance requirement that the receiving sensitivity frequency response be within the mask which can be drawn with straight lines between the breaking points in table 30 on a logarithmic (frequency) – linear (dB sensitivity) scale.
