Reference signal configuration for multi-transmit-receive point coherent joint transmission

A method comprising:

• receiving, from a user equipment (UE), a channel measurement resource (CMR) processing capability;
• generating a CMR configuration to configure a number of non-zero power (NZP) channel state information (CSI)-reference signal (RS) resources to support a multi-transmit-receive point (mTRP) coherent joint transmission (CJT);
• and
• outputting the CMR configuration for transmission to the UE.

A method comprising:

• generating, for transmission to a base station, a channel measurement resource (CMR) processing capability, wherein the CMR processing capability is to indicate user equipment (UE) support for:
• a maximum number of transmit ports per non-zero power (NZP) channel state information (CSI)-reference signal (RS) resource for a multi-transmit-receive point (mTRP) coherent joint transmission (CJT);
• a maximum total number of NZP CSI-RS resources associated with the mTRP CJT;
• and a maximum total number of transmit ports of NZP CSI-RS resources associated with the mTRP CJT;
• and
• outputting the CMR processing capability for transmission to a base station.

One or more non-transitory, computer-readable media having instructions that, when executed, cause processor circuitry to:

• generating, for transmission to a base station, a channel measurement resource (CMR) processing capability associated with a multi-transmit-receive point (mTRP) coherent joint transmission (CJT);
• output the CMR processing capability for transmission to a base station;
• and
• receive a CMR configuration to configure all NZP CSI-RS resources of an NZP CSI-RS resource set to be transmitted within a discontinuous reception (DRX) active time.
