Section: 8.9.1.2.2 Closed-loop spatial multiplexing performance (Cell-Specific Reference Symbols)
Content: 8.9.1.2.2.1 Minimum Requirement Single-Layer Spatial Multiplexing 2 Tx Antenna Port The requirements are specified in Table 8.9.1.2.2.1-2, with the addition of the parameters in Table 8.9.1.2.2.1-1 and the downlink physical channel setup according to Annex C.3.2. The purpose of these tests is to verify the closed loop rank-one performance with frequency selective precoding. Table 8.9.1.2.2.1-1: Test Parameters for Single-Layer Spatial Multiplexing (FRC) Table8.9.1.2.2.1-2: Minimum performance Single-Layer Spatial Multiplexing (FRC) 8.9.1.2.2.2 Minimum Requirement Single-Layer Spatial Multiplexing 4 Tx Antenna Port The requirements are specified in Table 8.9.1.2.2.2-2, with the addition of the parameters in Table 8.9.1.2.2.2-1 and the downlink physical channel setup according to Annex C.3.2. The purpose of these tests is to verify the closed loop rank-one performance with frequency selective precoding. Table 8.9.1.2.2.2-1: Test Parameters for Single-Layer Spatial Multiplexing (FRC( Table 8.9.1.2.2.2-2: Minimum performance Single-Layer Spatial Multiplexing (FRC) 8.9.1.2.2.3 Minimum Requirement Single-Layer Spatial Multiplexing 4 Tx Antenna Ports with CRS assistance information The requirements are specified in Table 8.9.1.2.2.3-2, with the addition of parameters in Table 8.9.1.2.2.3-1. In Table 8.9.1.2.2.3-1, Cell 1 is the serving cell, and Cell 2 and Cell 3 are the aggressor cells. The downlink physical channel setup is according to Annex C.3.2 for each of Cell 1, Cell 2 and Cell 3, respectively. The CRS assistance information [7] is provided to the UE and includes information on Cell 2 and Cell 3. The purpose of the test is to verify the closed loop single layer TM4 performance under assumption that UE applies CRS interference mitigation in the scenario with 4 CRS antenna ports in the serving and aggressor cells.
