Precoder estimation

A network node for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• transmit an indication, for a user equipment (UE), of a slot to be associated with precoder estimation, the indication of the slot including an indication of a first precoder and one or more parameters associated with the slot;
• transmit, during the slot, a first one or more reference signals, using the first precoder, and a second one or more reference signals using a second precoder;
• and
• transmit, using the second precoder, one or more signals for the UE.

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving, from a network node, an indication of a slot to be associated with precoder estimation, the indication of the slot including an indication of a first precoder and one or more parameters associated with the slot;
• receiving, from the network node and during the slot, a first one or more reference signals associated with estimating a physical channel using the first precoder and a second one or more reference signals associated with estimating a second precoder using the estimated physical channel;
• and
• receiving, from the network node, one or more signals based on the second precoder.
