11 Performance requirement (MBMS)
25.1013GPPRelease 17TSUser Equipment (UE) radio transmission and reception (FDD)
Unless otherwise stated the receiver characteristics are specified at the antenna connector of the UE. For UE(s) with an integral antenna only, a reference antenna with a gain of 0 dBi is assumed. UE with an integral antenna may be taken into account by converting these power levels into field strength requirements, assuming a 0 dBi gain antenna. For UEs with more than one receiver antenna connector the fading of the signals and the AWGN signals applied to each receiver antenna connector shall be uncorrelated. The levels of the test signal applied to each of the antenna connectors shall be as defined in the respective sections below.
11.1 Demodulation of MCCH
The receive characteristic of the MCCH is determined by the RLC SDU error rate (RLC SDU ER). The requirement is valid for all RRC states for which the UE has capabilities for MBMS.
11.1.1 Minimum requirement
For the parameters specified in Table 11.1 the average downlink S-CCPCH_Ec/Ior power ratio shall be below the specified value for the RLC SDU ER shown in Table 11.2.

11.2 Demodulation of MTCH
The receive characteristic of the MTCH is determined by RLC SDU error rate (RLC SDU ER). RLC SDU ER is specified for each individual data rate of the MTCH. The requirement is valid for all RRC states for which the UE has capabilities for MBMS.
11.2.1 Minimum requirement
For the parameters specified in Table 11.3 the average downlink S-CCPCH_Ec /Ior power ratio shall be below the specified value for the RLC SDU ER shown in Table 11.4. If the UE supports optional enhanced performance requirements type1 for MBMS then for the parameters specified in Table 11.3 the average downlink S-CCPCH_Ec /Ior power ratio shall be below the specified value for the RLC SDU ER shown in Table 11.4a.

11.3 Demodulation of MTCH and cell identification
MBMS combining is not controlled by a network but instead it is autonomously handled by a terminal. UE has to be able to receive MTCH and identify intra-frequency neighbour cells according to the requirements. The receive characteristic of the MTCH combined with cell identification is determined by RLC SDU error rate (RLC SDU ER).
11.3.1 Minimum requirement
For the parameters specified in Table 11.5 the average downlink S-CCPCH_Ec/Ior power ratio shall be below the specified value for the RLC SDU error rate shown in Table 11.6. The cell reselection parameters are given in clause A.9 in Table A.34. The different cells are assumed to be time aligned.
