Abstract
A method for notifying a downlink demodulation pilot control signaling, includes: a base station side notifying a user equipment (UE) side of an index of a virtual signaling group and/or index of port offset signaling group used when generating a downlink pilot sequence and/or mapping the generated downlink pilot sequence through at least one of the following information: UE-specific or common high layer signaling; antenna indication information of DL_Grant; new data indication information in a Disable TB signaling in the DL_Grant; scrambling indication information in the DL_Grant; in a UE-specific or common search space, an aggregation level of the DL_Grant, a relative position of a first control channel element of the DL_Grant in the UE-specific or common search space, a subframe number where the DL_Grant is located and a system frame number where the DL_Grant is located.
