6.2.2B_1.1 Test purpose
Same test purpose as in clause 6.2.2B.1.
6.2.2B_1.2 Test applicability
This test case applies to all types of E-UTRA Power Class 2 UE release 10 and forward that support UL MIMO.
6.2.2B_1.3 Minimum conformance requirements
For Power Class 2 UE with two transmit antenna connectors in closed-loop spatial multiplexing scheme, the maximum output power for any transmission bandwidth within the channel bandwidth is specified in Table 6.2.2B_1.3-1 with the UL-MIMO configurations specified in Table 6.2.2B.3-2. The maximum output power is measured as the sum of the maximum output power at each UE antenna connector. The period of measurement shall be at least one sub frame (1ms).

Note 1: The above tolerances are applicable for UE(s) that support up to 4 E-UTRA operating bands. For UE(s) that support 5 or more E-UTRA bands the maximum output power is expected to decrease with each additional band and is FFS Note 2: For transmission bandwidths (Figure 5.4.2-1) confined within FUL_low and FUL_low + 4 MHz or FUL_high – 4 MHz and FUL_high, the maximum output power requirement is relaxed by reducing the lower tolerance limit by 1.5 dB Note 3: PPowerClass is the maximum UE power specified without taking into account the tolerance |

For a power class 2 capable UE operating on Band 41, when an IE P-max as defined in [5] of 23 dBm or lower is indicated in the cell or if the TDD frame configuration is 0 or 6, the requirements for power class 2 are not applicable and the corresponding requirements for a power class 3 UE shall apply.
The normative reference for this requirement is TS 36.101 clause 6.2.2B.

Note 1: Test Channel Bandwidths are checked separately for each E-UTRA band, the applicable channel bandwidths are specified in Table 5.4.2.1-1. Note 2: If the test channel bandwidth is larger than 4MHz, then the 1 RB allocation shall be tested at both RB #0 and RB #max. |
