Systems and methods for downlink control information for multiple-user superposition transmission

Abstract

A method for communicating downlink control information (DCI) by an evolved Node B (eNB) is described. The method includes configuring a first user equipment (UE) and a second UE for multi-user superposition transmission (MUST). The method also includes configuring the first UE and the second UE to interpret a repurposed DCI format that points to an address of a second DCI format. The method further includes sending the repurposed DCI format that is scrambled with a first UE-specific cell radio network temporary identifier (C-RNTI). The method additionally includes sending the repurposed DCI format that is scrambled with a second UE-specific C-RNTI. The method also includes sending the second DCI format that is scrambled with a MUST-RNTI known to both the first UE and the second UE. The method further includes sending PDSCH according to the second DCI format scrambled by the MUST-RNTI.
