摘要： A system and method for reporting feedback information for adaptive codebooks include generating channel state information, encoding all or part of the channel state information to produce a feedback payload and transmitting the feedback payload to a base station from a mobile station. The channel state information may comprise one or more of a rank indicator, a first matrix indicator, a wideband channel quality indicator, a second matrix indicator and at least one narrowband channel quality indicator. When the rank indicator is greater than 1, the first matrix indicator is reported in a second report. On the other hand, when the rank indicator is equal to 1, the content of the first matrix indicator is split between a second report and a third report.

摘要： A signal sending method, a signal receiving method, and a device are provided. A part that is of a first signal and that is carried on the k th subcarrier in the i th subcarrier group in N subcarrier groups is x i,n id (k), and a sequence (s i,n id (k)} related to x i,n id (k) is one of enumerated sequences. The enumerated sequences are sequences with relatively good cross-correlation. Therefore, for two subcarrier groups, provided that selected {s i,n id (k)} is two of the enumerated sequences, cross-correlation between signals carried in the two subcarrier groups can be ensured to be relatively good, thereby reducing interference between the signals and improving channel estimation performance.

摘要： The present invention relates to a method for reporting channel state information, a user equipment, and a base station. A channel state information measurement resource is determined by a UE according to an aperiodic CSI (Channel State Information) trigger signaling, so that a base station transmits a CSI-RS (Channel State Information-Reference Signal) only when the UE needs to report the aperiodic CSI. Compared with transmitting a periodic CSI-RS by an existing base station, unnecessary transmitting of the CSI-RS is reduced, and energy of the base station such as an eNB is saved; and reducing the CSI-RS transmission may reduce resources occupied by the CSI-RS, thereby improving the spectrum efficiency of the system. In addition, reducing unnecessary CSI-RS transmission allows the interference in other cells by the base station being reduced; finally, CSI measurement resources are reserved only when the CSI needs to be fed back, the cost occupied by the CSI measurement resources is reduced, thereby improving the spectrum efficiency of the system.
