Abstract: A new air interface that is interference cancellation friendly is proposed. In one novel aspect, addition information is provided between eNB and UE for interference cancellation. From eNB perspective, it provides assistance information to UEs for CWIC. The assistance information may include modulation order and code rate information of the PDSCH for data transmission that may cause interference to other UEs. From UE perspective, it provides feedback information to the eNB for MCS level assignment. The feedback information may include additional channel quality and interference condition information of a data transmission of a desired transport block with respect to the decoding of the desired transport block.
