摘要： The present invention discloses a method and apparatus for rank self-adaptation. The method comprises: a base station receiving ranks reported by a user equipment via a rank receiving window, determining a rank at the current moment based on a distribution state of each rank in the rank receiving window at the current moment, and determining the number of independent channels used for sending downstream data to the user equipment based on the rank at the current moment. The present invention can reasonably forecast change of ranks of MIMO channels so as to better use MIMO channel resources to perform data transmission and improve the throughput rate of the MIMO channels.

摘要： The present invention provides a method and an apparatus for processing a precoder. The method comprises: step A: a base station determining whether the number of received effective precoders reported by a certain UE is greater than or equal to a threshold a, if so, executing step B, otherwise, executing step D; step B: the base station determining whether each received effective precoder is according to the same number of layers, if so, executing step C, otherwise, executing step D; step C: the base station determining whether a variation speed of each effective precoder is fast, if so, applying a transmit diversity transmission mode to the UE, otherwise, applying a MIMO transmission mode to the UE; and step D: applying the MIMO transmission mode to the UE. Therefore, the present invention can reasonably predict the transmission mode and the precoder that should be employed in the transmission mode at current time for a certain UE.

摘要： The disclosure discloses a method and device for reporting channel state information aperiodically. Wherein the method comprises: collecting the channel state information reported by the UE through the configured receiving window; determining the change speed degree of the channel state of the UE according to the criterion for determining a change speed of the channel state information; deciding whether the UE needs to perform aperiodic reporting according to the mapping relationship between the change speed degree of the channel state information and a reporting period adjusting value, and determining timing for the aperiodic reporting if needed. By the method of the disclosure, on one hand, the base station sufficiently obtains the channel state information reported by the UE, which benefits for more suitable scheduling and resource allocating for the UE; on the other hand, PUSCH resources can be used more rationally.
