When SM-MIMO is used for sharing the same resources for multiple users (MU-SM), the control information describing the parameters of MU-SM need to be sent separately to all the users that may be sharing the same resources. The base station in a wireless communication system may only provide the parameters required by each specific client terminal for decoding the data addressed to it. A method and apparatus are disclosed that enable improved decoding of MU-SM signals in scenarios where information about the parameters of other transmissions on the same resources or absence of any transmission other than the one intended for the subject client terminal is not available."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for a multi-user spatial multiplexing decoder","description":"Spatial Multiplexing (SM) with Multiple Input Multiple Output (MIMO) is used in many wireless communication systems for providing high data rate in a given channel bandwidth.
