METHOD FOR DETERMINING BASE SEQUENCE AND CYCLIC SHIFT HOPPING AND DEVICE THEREOF

摘要

A method for determining a base sequence and cyclic shift hopping is used for uplink channel and signal transmission of a user equipment in a coordinated multi-point (CoMP) transmission system. The method comprises: configuring a relevant parameter, the relevant parameter comprising multiple user-dedicated virtual cell identifiers, or multiple parameter information groups and each parameter information group comprising user-dedicated virtual cell identifiers respectively used for determining a base sequence and cyclic shift hopping, or multiple parameter information groups and each parameter information group comprising a user-dedicated virtual cell identifier and a user-dedicated sequence group allocation number Deltass; selecting a parameter used for determining a base sequence and cyclic shift hopping for uplink channel and signal transmission from the configured relevant parameter; and notifying a user equipment of the selected parameter, so that the user equipment determines the base sequence and cyclic shift hopping according to the parameter. By means of the embodiments of the present invention, signaling overhead can be saved and the system performance is ensured.
