Multi-TRP Interference Control in Wireless Communications

A method, comprising:

• receiving, by a processor of a user equipment (UE), from a first network node of a wireless network a downlink (DL) measurement reference signal;
• configuring, by the processor, an interference measurement resource (IMR) associated with a sounding reference signal (SRS) resource of the UE based on the DL measurement reference signal;
• measuring, by the processor, an interference using the IMR;
• generating, by the processor, a precoder based at least in part on the measured interference;
• and
• performing, by the processor, an uplink (UL) transmission to the first network node using the precoder such that an amount of interference caused by the UL transmission on a second network node of the wireless network is reduced.

An apparatus, comprising:

• a processor capable of:
• receiving from a network node of a wireless network a downlink (DL) measurement reference signal;
• configuring a channel measurement resource (CMR) associated with a sounding reference signal (SRS) resource of the apparatus based on the DL measurement reference signal;
• configuring an interference measurement resource (IMR) associated with the SRS resource based on the DL measurement reference signal;
• measuring a channel response of a communication channel between the UE and the network node using the CMR;
• measuring an interference using the IMR;
• generating a precoder based on the measured channel response and the measured interference;
• and
• performing an uplink (UL) transmission to the network node using the precoder.
