Reallocation method of the physical share channel

The invention relates to a mobile communication field, discloses a physical shared channel reconfiguration method capable of ensuring accuracy of wireless downlink control channel configuration. In the invention, a base staion node uses scrambling code configuration E-RGCH, E-HICH and E-AGCH corresponding to a downlink reference channel of a physical shared channel, the scrambling code is configured in the base staion node before establishing a cell, and a scrambling code used by E-RGCH, EHICH and E-AGCH is forbidded to be directly configured by a CRNC via an NBAP message. During the reconfiguration process of the physical shared channel of the NBAP, the invention allows changing a reference channel of the physical shared channel of the cell.
