7.7 Spurious response

25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

Spurious response is a measure of the receiver’s ability to receive a wanted signal on its assigned channel frequency without exceeding a given degradation due to the presence of an unwanted CW interfering signal at any other frequency at which a response is obtained i.e. for which the blocking limit is not met.

7.7.1 Minimum Requirement

7.7.1.1 3.84 Mcps TDD Option

For non-IMB operation, the BER shall not exceed 0.001 for the parameters specified in Table 7.8.

For IMB operation, the BLER shall not exceed 0.01 for the parameters specified in Table 7.8.

Table 7.8: Spurious Response (3.84 Mcps TDD Option)

Parameter	Level	Unit
	0 *	dB
	-102	dBm/3.84 MHz
(CW)	-44	dBm
F_uw	Spurious response frequencies	MHz
NOTE *: Subtract 0.77dB when using the IMB DL reference measurement channel. For IMB the term DPCH_Ec refers to the sum of the energy of the physical channels comprising the IMB DL reference measurement channel.

7.7.1.2 1.28 Mcps TDD Option

The BER shall not exceed 0.001 for the parameters specified in Table 7.8A.

7.7.1.3 7.68 Mcps TDD Option

The BER shall not exceed 0.001 for the parameters specified in Table 7.8B.

7.7.2 Additional requirement of multi-carrier reception for 1.28Mcps TDD Option

The BLER measured on each carrier shall not exceed 0.1 for the parameters specified in Table 7.8AA.
