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.
Abstract:
A downlink control information configuration and acquisition method, base station and terminal. The base station configures a plurality of sets of received information for the terminal via dedicated high-layer signalling of the terminal, and the base station indicates which set of the plurality of sets of received information is to be used by the terminal to receive a DMRS and/or physical downlink shared channel (PDSCH) using at least one of the following pieces of information: LVRB/DVRB bits allocated by a centralized/distributed virtual resource block in the DCI Format 1A; a control channel mode in which the DCI Format 1A is located: a PDCCH and an ePDCCH; an ePDCCH transmission mode in which the DCI Format 1A is located: a diversity transmission mode and a centralized transmission mode; and an ePDCCH cluster in which the DCI Format 1A is located.
