Abstract

An approach is described for a user equipment (UE) to receive a channel state information (CSI) reporting configuration message from a source device of a first cell and receive a channel state information reference signal (CSI-RS) from a second cell via the source device. The UE determines a first number of CSI-RS resources of a first time slot duration corresponding to the first cell, a second number of CSI-RS resources of a second time slot duration corresponding to the second cell, an overall time slot duration based on the first and the second time slot duration, an overall number of CSI-RS resources of the overall time slot duration based at least on the first and the second number of CSI-RS resource, generates a capability report at least based on the overall number of CSI-RS resource, and transmits the capability report to the source device.
