8.11 Detection of Broadcast channel (BCH)
25.1013GPPRelease 17TSUser Equipment (UE) radio transmission and reception (FDD)
The receiver characteristics of Broadcast Channel (BCH) are determined by the Block Error Ratio (BLER) values. BCH is mapped into the primary common control physical channel (P-CCPCH).
8.11.1 Minimum requirement without transmit diversity
For the parameters specified in Table 8.40 the average downlink power P-CCPCH_Ec/Ior shall be below the specified value for the BLER shown in Table 8.41. (The Down link Physical channels are specified in Annex C).
This requirement doesn’t need to be tested.

8.11.2 Minimum requirement with open loop transmit diversity
For the parameters specified in Table 8.41A the average downlink power P-CCPCH_Ec/Ior shall be below the specified value for the BLER shown in Table 8.41B. (The Down link Physical channels are specified in Annex C).
This requirement doesn’t need to be tested.
