4.3.3.1 Antennas
If the UE has two Rx antennas, the same downlink signal is applied to each one. Both UE Rx antennas shall be connected unless otherwise stated in the test case.
If the UE has one Rx antenna, the downlink signal is applied to it.
4.3.3.2 Downlink physical channels and physical signals
The Downlink Physical channels and Physical signals used and their relative powers are specified for single SS Tx antenna in table 4.3.3.2-1 and for two SS Tx antennas in table 4.3.3.2-2. The details of downlink power allocation for PDSCH channel are described in TS 36.213 [29] clause 5.2. For BL-UE testing, PHICH is not required and MPDCCH is required.

4.3.3.3 Mapping of downlink physical channels and signals to physical resources
Parameters for mapping of downlink physical channels and signals are specified as follows.
Normal Cyclic Prefix
, Physical layer cell identity = 0 is used as the default physical layer cell identity
CFI = 3 for 1.4, 3 and 5 MHz system bandwidths
= 2 for 10, 15 and 20 MHz system bandwidths
= 2 if PMCH is configured (‘mbsfn-SubframeConfiguration’ is present in SIB2)
Ng = 1
PHICH duration = Normal
For Signalling testing, the default system bandwidth is 5/10/20 MHz and single SS Tx antenna is used unless specified otherwise in the test case. The mapping of downlink physical channels to physical resources for Single Tx Antenna is described in table 4.3.3.3-1 for 5/10MHz system bandwidth FDD and table 4.3.3.3-2 for 5/20MHz system bandwidth TDD.
For RF testing, the mapping of DL physical channels to resource element is defined TS 36.521-1 [21] Annex C.1.
