A wireless base station comprises a response vector calculation unit, an RSSI measuring unit, an MSE calculation unit, an FD calculation unit and the like, and those units obtain an index showing communication quality of at least one of two mobile stations that are intended to be space-division multiplexed. The oxidation exhaust trap has a vessel having an interior cavity. The dynamic stage is further triggered by a clock signal thereto. The method in the embodiment of the present invention comprises: the UE measures a downlink channel and determines a downlink channel matrix; the UE determines a first weighting matrix for aerial calibration according to the downlink channel matrix; the UE notifies a network side of the determined first weighting matrix. The method includes sending at least one control or configuration message corresponding to each HARQ entity of at least one HARQ entity or at least one HARQ process of an HARQ entity to the UE to set transmission grant of the UE when the UE performs uplink transmission through the at least one HARQ entity or the at least one HARQ process of the HARQ entity.
