Abstract
Methods, systems, and devices for wireless communications are described. A network node may transmit a control message to one or more user equipment (UEs) that identifies that multi-user multiple input multiple output (MU-MIMO) signals from the network node include one or more private messages for a UE and one or more common messages for a UE and at least one other UE. The network node may transmit an additional control message that identifies a first phase tracking reference signal (PTRS) port for the one or more private messages and a second PTRS port for the one or more common messages, where the PTRS ports may be the same or different. Then, the network node may transmit the private messages using the first PTRS port and the common messages using the second PTRS port.
