1. A method for a network node, comprising:
encoding a non-zero-power channel state information reference signal (NZP-CSI-RS) configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) associated with a serving cell and a second TRP associated with a neighbor cell, the NZP-CSI-RS configuration communication including a first group of NZP-CSI-RS resources for the serving cell and a second group of NZP-CSI-RS resources for the neighbor cell,
wherein the second group of NZP-CSI-RS resources for the neighbor cell comprises a powerControlOffset element for the neighbor cell, wherein the powerControlOffset element is used when a NZP-CSI-RS is configured for Link Adaption CSI, and
wherein the second group of NZP-CSI-RS resources for the neighbor cell comprises a powerControlOffsetSS element and wherein a reference power of powerControlOffsetSS element is a Secondary Synchronization Signals (SSS) transmit power of the serving cell or a SSS transmit power of the neighbor cell;
decoding a NZP-CSI-RS measurement communication received from the UE, the NZP-CSI-RS measurement communication being based on the NZP-CSI-RS configuration communication; and
based on the NZP-CSI-RS measurement communication, scheduling one or more downlink data transmissions.
