Antenna port tables for physical downlink shared channel with increased number of frequency division codes

A method by a network node for transmitting a physical downlink shared channel, PDSCH, transmission, the method comprising:

• transmitting, to a User Equipment, UE, in a Downlink Control Information, DCI, information about two or more Demodulation Reference Signal, DMRS, ports in a Code Division Multiplexing, CDM, group associated to the PDSCH transmission, wherein:
• the two or more DMRS ports are orthogonal at a length n, and
• the two or more DMRS ports are orthogonal over a partial length n′ that is less than n, and
• transmitting, to the UE, the PDSCH transmission with the two DMRS ports in the CDM group.

A user equipment, UE, for receiving a physical downlink shared channel, PDSCH, transmission, the UE adapted to:

• receive, from a network node, in a Downlink Control Information, DCI, information about two or more Demodulation Reference Signal, DMRS, ports in a Code Division Multiplexing, CDM, group associated to the PDSCH transmission, wherein:
• the two or more DMRS ports are orthogonal at a length n, and
• the two or more DMRS ports are orthogonal over a partial length n′ that is less than n, and
• receive, from the network node, the PDSCH transmission with the two or more DMRS ports in the CDM group.
