For the single-antenna port transmission schemes (port 0/5/7/8/11/13) of the PDSCH, the UE may assume that an eNB transmission on the PDSCH would be performed according to Clause 6.3.4.1 of [3].

If the UE is not configured with higher layer parameter dmrs-tableAlt and in case an antenna port is used, or if the higher layer parameter dmrs-tableAlt is set to 1 and in case an antenna port corresponding to one codeword values 0-3 in Table 5.3.3.1.5C-2 [4] is used, the UE cannot assume that the other antenna port in the set is not associated with transmission of PDSCH to another UE.

If the UE is configured with higher layer parameter dmrs-tableAlt, and in case of single layer transmission scheme on antenna port corresponding to one codeword values 4-11 in Table 5.3.3.1.5C-2 [4] is used, the UE cannot assume that the other antenna ports in the set is not associated with transmission of PDSCH to another UE.
