Sounding reference signal via downlink port

A network node for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to cause the network node to:
• output, to a user equipment (UE), a full duplex configuration for configuring the UE to:
• use one or more downlink ports and one or more uplink ports simultaneously, and
• transmit, via the one or more downlink ports, a sounding reference signal (SRS) for downlink channel sounding;
• and
• receive the SRS in a downlink band of a sub-band full duplex (SBFD) slot.
