More Information
Summary:A resource allocation for a specific user equipment (UE) is encoded using an encoding scheme that identifies a specific antenna port from among a plurality of antenna ports; and the encoded resource allocation is output to the specific antenna port for transmission to the specific UE. The encoding scheme comprises attaching a cyclic redundancy check (CRC) and masking it with an identifier of the specific UE. The UE blindly detects its control channel and determines its resource allocation by decoding the control channel using a decoding scheme that identifies a specific antenna port from among the plurality of transmit antenna ports. In various embodiments, the scheme is in scrambling or masking (using an ID of the antenna port or UE); by the order of bits when encoding, port specific mapping constellations, and adding bits that give the port index.
