摘要: A method, mobile terminal, and system for reporting BCI are provided, the method comprises steps of: obtaining a PMI W1 set W2 to be used terminal based on double codebook; computing another set; selecting from W2; base station, wherein indicates long-term or wideband component of BCI, short-term narrowband BCI. With present disclosure, probability that optimal is included in shifted increased, overhead feeding-back reduced.
