USER EQUIPMENT ENHANCEMENTS FOR COOPERATIVE MULTI POINT COMMUNICATION

摘要

Certain aspects of the present disclosure provide techniques for measuring interference observed at a CoMP UE caused by neighbor base stations transmitting reference signals. The present disclosure provides a method for wireless communication comprising: determining at a user equipment UE served by at least one base station BS a reference signal RS configuration indicating resources on which one or more neighbor BSs transmit RS or data; estimating interference observed at the UE caused by the neighbor BSs based on RS or data transmitted by the neighbor BSs on the indicated resources; computing a channel state information CSI using said interference estimate; and sending the CSI to the serving BS for use in coordinating transmissions with the neighbor BSs.
