UPLINK PRECODING METHOD IN 2 -TX SYSTEM |
摘要 |
A method for a user equipment to precode and transmit an uplink signal efficiently in a 2-antenna system and a method for a base station to receive the transmitted signal efficiently are disclosed. A 2-antenna codebook includes 4 DFT matrixes and 2 antenna selection matrixes for a rank 1 and one identity matrix for a rank 2 as precoding matrixes. For efficient uplink signal transmission/reception, the present invention provides signal transceiving technology between user equipment and base station using the 2-antenna codebook. |
