7.8 Intermodulation characteristics
25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)
Third and higher order mixing of the two interfering RF signals can produce an interfering signal in the band of the desired channel. Intermodulation response rejection is a measure of the capability of the receiver to receiver a wanted signal on its assigned channel frequency in the presence of two or more interfering signals which have a specific frequency relationship to the wanted signal.
7.8.1 Minimum Requirements
7.8.1.1 3.84 Mcps TDD Option
For non-IMB operation, the BER shall not exceed 0.001 for the parameters specified in table 7.9.
For IMB operation, the BLER shall not exceed 0.01 for the parameters specified in table 7.9.
