METHOD AND TERMINAL FOR FEEDBACK OF CHANNEL STATUS INFORMATION

摘要

Disclosed are a method and terminal for feedback of channel status information, said method comprising: the terminal acquiring channel status information including channel quality indicator (CQI) information, precoding matrix indicator (PMI) information and rank indicator (RI) information. In an eight-antenna system, PMIs include a first PMI (PMI1) and a second PMI (PMI2), while in a four-antenna system, PMI comprises a single PMI; a terminal on a physical uplink shared channel (PUSCH) feeds back information according to a preset feedback method. The present invention enhances performance in communication systems.
