Base station, mobile station and method for downlink scheduling

A method for downlink scheduling by a base station, comprising:

• assigning a downlink resource block and a number of streams, an antenna port and a scrambling identity for the antenna port to a mobile station, wherein a combination of the number of streams, the antenna port and the scrambling identity determines a successive interference cancellation order of the mobile station in the downlink resource block;
• and
• transmitting downlink scheduling information to the mobile station, the downlink scheduling information including information indicating the downlink resource block and information indicating the number of streams, the antenna port and the scrambling identity.

A mobile station, comprising:

• a receiving unit, configured to receive downlink scheduling information transmitted by a base station, the downlink scheduling information including information indicating a downlink resource block assigned to the mobile station and information indicating a number of streams, an antenna port and a scrambling identity for the antenna port, which are assigned to the mobile station;
• and
• a determining unit, configured to determine a successive interference cancellation order of the mobile station in the downlink resource block based on a combination of the number of streams, the antenna port and the scrambling identity.
