Antenna port tables for physical uplink shared channel with increased number of frequency domain codes

A method by a network node for receiving a physical uplink shared channel, PUSCH, transmission from a User Equipment, UE, the method comprising:

• transmitting, to the 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 PUSCH 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
• receiving, from the UE, the PUSCH transmission with the two DMRS ports in the CDM group.

A user equipment, UE, for transmitting a physical uplink shared channel, PUSCH, 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 PUSCH 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
• transmit, to the network node, the PUSCH transmission with the two or more DMRS ports in the CDM group.
