8.7.1 ACK missed detection requirements for single user SPUCCH format 1a

The ACK missed detection probability is the probability of not detecting an ACK when an ACK was sent.

8.7.1.1 Minimum requirements

The ACK missed detection probability shall not exceed 1% at the SNR given in Table 8.7.1.1-1.

Table 8.7.1.1-1: Minimum requirements for single user SPUCCH format 1a, 1Tx

Number of TX antennas	Number of RX antennas	Cyclic Prefix	Propagation conditions and correlation matrix (Annex B)	Channel Bandwidth / SNR [dB]
				5 MHz	10 MHz	15 MHz	20 MHz
1	2	Normal	EPA 5 Low	3.7	3.6	3.8	3.8
	4	Normal	EPA 5 Low	-0.1	-0.2	-0.1	-0.1

8.7.2 ACK missed detection requirements for SPUCCH format 4

The ACK missed detection probability is the probability of not detecting an ACK bit when an ACK bit was sent on the particular bit position, with each missed ACK bit being accounted as one error.

The number of encoded ACK/NACK bits per subslot is 3. The transmitted subslots include both subslot with =2 and subslot with =3.

8.7.2.1 Minimum requirements

The ACK missed detection probability shall not exceed 1% at the SNR given in table 8.7.2.1-1 for 3 AN bits per subslot.
