Using the PCR, a PMI maximizing transmission performance and PMIMin minimizing interference to a neighboring base station are combined into the uplink precoding matrix W. Overall operations of a system can be simplified and the load of calculation for generating the uplink precoding matrix W in the mobile station can be reduced, because the PCR is provided by the base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting recording information for uplink transmission in multi base station MIMO system","description":"A PMI combination ratio (PCR) being used for generating a uplink precoding matrix W is transmitted by a base station to a mobile station.
