1. A method for a base station in a wireless network, the method comprising:
receiving a message from a first user equipment (UE) indicating a supported mode for UE coordination based channel state information (CSI) feedback;
based on the supported mode, configuring the first UE and one or more second UE for either a first mode wherein both the first UE and the one or more second UE perform CSI measurements to be reported by the first UE or a second mode wherein only the first UE performs the CSI measurements to be reported by the first UE;
triggering CSI reporting for the first UE and the one or more second UE in a coordination group; and
processing one or more CSI report from the first UE for the first UE and the one or more second UE in the coordination group.
