1. A method of wireless communication, comprising:
transmitting, by a network node to a wireless device, a configuration of at least one channel state information (CSI) reference signal (RS) and a configuration of a CSI report,
wherein the configuration of the at least one CSI-RS includes a number of CSI-RS ports mapped to a combination of vector pairs, and wherein the configuration of the CSI report includes a number of the vector pairs;
transmitting, based on the configuration over one or more CSI-RS resources, the at least one CSI-RS; and
receiving, from the wireless device, the CSI report based on the configuration of the CSI report, wherein the CSI report comprises a precoding matrix indicator (PMI), wherein a precoding matrix associated with the PMI comprises the combination of vector pairs mapped to the number of CSI-RS ports.
