Content: 8.1.2.12.1.1 Applicability rule and antenna connection for single carrier PDSCH tests with 2Rx and 4Rx For 8Rx capable UEs, all single carrier tests specified in 8.2 to 8.8 with 2Rx are tested on any of the 2Rx supported RF bands by connecting 2 out of the 8Rx with data source from system simulator, and the other 6 Rx are connected with zero input, depending on UE’s declaration and AP configuration. Same requirements specified with 2Rx should be applied. For 8Rx capable UEs, all single carrier test cases specified in 8.10 with 4Rx are tested on any of the 4Rx supported RF bands by connecting 4 out of 8 Rx with data source from system simulator, and the other 4 Rx are connected with zero input, depending on UE’s declaration and AP configuration. Same requirements specified with 4Rx should be applied. For 8Rx capable UEs without support of any 4Rx RF bands, all single carrier tests specified in 8.10 with 4Rx are tested on any of the 8Rx supported RF bands by duplicating the fading channel from each Tx antenna and add independent noise for each Rx antenna. The SNR requirements should be applied with 1.5 dB less than the number specified for 4Rx tests. For 8Rx capable UEs without support of any 2Rx and 4Rx RF bands, all single carrier tests specified in 8.2 to 8.8 with 2Rx are tested on any of the 8Rx supported RF bands by duplicating the fading channel from each Tx antenna and add independent noise for each Rx antenna. The SNR requirements should be applied with 3 dB less than the number specified for 2Rx tests. For 8Rx capable UEs without support of any 2Rx RF bands but with support of 4Rx RF bands, all single carrier tests specified in 8.2 to 8.8 with 2Rx are tested on any of the 4Rx supported RF bands by duplicating the fading channel from each Tx antenna and add independent noise for each Rx antenna. 4 out of 8 Rx are connected with data source from system simulator, and the other 4 Rx are connected with zero input, depending on UE’s declaration and AP configuration. SNR requirements should be applied with 1.5 dB less than the number specified for 2Rx tests. Figure 8.1.2.12.1-1 ~ Figure 8.1.2.12.1-4 show examples of antenna connection for 8Rx capable UE in any one 8Rx supported RF band to perform a 2Rx or 4Rx performance test with antenna configuration as 2x2 or 4x2 for 2Rx tests and 2x4 or 4x4 for 4Rx tests without interference for information.

Table 8.1.2.12.1-1: Requirement lists with 2Rx not applicable to 8Rx capable UEs For 8Rx capable UEs without any 4Rx supported RF bands, for all single carrier tests listed in Table 8.1.2.12.1-2 specified in 8.10 with 4Rx can be skipped. Table 8.1.2.12.1-2: Requirement lists with 4Rx not applicable to 8Rx capable UEs For 8Rx capable UEs, if corresponding tests listed from the 8Rx test lists from Table 8.1.2.12.1-3 are tested, the test coverage can be considered fulfilled without executing the corresponding tests listed from botht the 4Rx test lists and the 2Rx test lists from Table 8.1.2.12.1-3. For 8Rx capable UEs, if corresponding tests listed from the 4Rx test lists from Table 8.1.2.12.1-3 are tested, the test coverage can be considered fulfilled without executing the corresponding tests listed from the 2Rx test lists from Table 8.1.2.12.1-3.
