Section: 8.10.1.2.13 Performance requirements for DCI format 2D and non Quasi Co-located Antenna Ports
Content: 8.10.1.2.13.1 Minimum requirements for QCL Type C and 3 Layers Spatial Multiplexing The requirements are specified in Table 8.10.1.2.13.1-3, with the additional parameters in Table 8.10.1.2.13.1-1 and Table 8.10.1.2.13.1-2. The purpose of this test is to verify the UE capability of supporting non quasi-colocated antenna ports when the UE receives DCI format 2D in a scenario with non-coherent joint transmission from two transmission points. The test verifies that the UE configured with quasi co-location type C performs correct tracking and compensation of the frequency and time difference between two transmission points, channel parameters estimation, channel estimation and rate matching behaviour according to the ‘PDSCH RE Mapping and Quasi-Co-Location Indicator’ signalling defined in [6]. In Table 8.10.1.2.13.1-1, transmission point 1 (TP 1) is the serving cell transmitting PDCCH, synchronization signals, PBCH and PDSCH, and transmission point 2 (TP 2) has different Cell ID and transmits PDSCH. In the test the PDSCH is transmitted from TP 1 and TP 2. The downlink physical channel setup for TP 1 is according to Annex C.3.2 and for TP 2 according to Annex C.3.2.
