Método para reducir el gasto general de información de realimentación en sistemas MIMO OFDM precodificados |
摘要 |
An improved method for reducing an amount of precoding feedback information in a multi-carrier Multiple-Input Multiple-Output (MIMO) communication system using precoding is disclosed. At the receiving end, the method jointly selects, while considering transmission quality for each relevant combination of sub-bands and matrices, a limited number of P codebook indices and a limited number of K' sub-bands to be included in a subset É ( m 1 ,..., m K ' ) of a set © of allowed sub-bands. K' is here set to a value K' < K and P is set to a value P ‰¤ K'. The P codebook indices and information identifying the subset É is then conveyed to the transmitting end. |
