Dynamic Switching Between Legacy and Extended DMRS Procedures

An extended antenna port table includes both legacy Demodulation Reference Symbols, DMRS, and extended DMRS (e.g., Rel-18 DMRS). A UE obtains an indication of the extended antenna port table, either from configured information in memory or from the network, such as via RRC signaling. The indication may be of a subset of the extended antenna port table. The network sends the UE an index into the extended antenna port table, from which the UE determines one or more DMRS ports to use (one per layer). The extended DMRS ports in the extended antenna port table that are the same as corresponding legacy DMRS ports reuse the legacy DMRS port numbers; and extended DMRS ports that are different than legacy DMRS ports use DMRS port numbers not used by legacy DMRS ports. In one embodiment, the network switches the UE between using legacy and extended antenna port tables via a MAC-CE.
