Title:
An uplink signal transfer method and a device using a multiplex antenna
Document Type and Number:
Japanese Patent JP6196268
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an uplink signal transfer method for making a user apparatus use a multiple-input and multiple-output (MIMO) system.SOLUTION: When a user apparatus transfers an uplink signal through a MIMO system, a precoding system is provided, which use a precoding matrix preset so that one hierarchy is transferred for each antenna in a specific at specific rank transfer in order to maintain a peak power against average power ratio (PAPR) or tertiary measurement (CM: cubic metric) characteristics to be satisfactory.SELECTED DRAWING: Figure 14
