Abstract:
1. A method for transmitting power offset information of a secondary common pilot channel, comprising: a drift radio network control receiving request information sent by a serving radio network control and used for requesting the drift radio network control to feed back power offset information of respective secondary common pilot channels of target primary and secondary carrier cells managed by the drift radio network control, the drift radio network control setting following information elements with reference to multiple-input multiple-output (MIMO) pilot modes used respectively by the target primary and secondary carrier cells: an information element of power offset information of a secondary common pilot channel of a single carrier cell, an information element of power offset information of a secondary common pilot channel of a primary carrier cell, and an information element of power offset information of a secondary common pilot channel of a secondary carrier cell, and feeding back the set information elements to the serving radio network control through an interconnection interface between the radio network controls; wherein, the MIMO pilot modes used respectively by the target primary and secondary carrier cells include: whether the target primary carrier cell uses the MIMO pilot mode of the primary and secondary common pilot channels in a downlink direction and whether the target secondary carrier cell uses the MIMO pilot mode of the primary and secondary common pilot channels in a downlink direction.
