Description

Method, base station and the subscriber equipment of resource mapping

Technical field

The embodiment of the present invention relates to multipoint cooperative communication system, and more specifically, relates to method, base station and the subscriber equipment of resource mapping in multipoint cooperative communication system.

In multipoint cooperative communication system, except the serving BS of subscriber equipment, also may there be multiple cooperative base station to provide downlink transfer service for this subscriber equipment.Wherein, each base station sends respectively data and cell special reference (Cell-specific Reference Signal to this subscriber equipment, referred to as " CRS ") shared resource element (Resource Element, referred to as " RE ") be changeless, but, different base stations respectively to these user device transmissions data during with CRS shared RE different, and subscriber equipment is receiving when data and do not know these data by which base station are sent, therefore, this subscriber equipment can not be determined the position of the RE that receives data.

Can correctly identify in order to make this subscriber equipment the RE that receives data, first the serving BS of this subscriber equipment is this user device configuration Physical Downlink Shared Channel resource mapping colocation site (Physical Downlink Shared Channel Resource Element Mapping and Quasi-Co-Location, referred to as " PQ ") parameter sets, this PQ parameter sets comprises quadruplet PQ parameter, wherein, every cover PQ parameter all comprises the port number of CRS, CRS is in the position of frequency domain, zero energy CSI-RS(Channel State Indication Reference Signal, referred to as " CSI-RS ") configuration information, Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as " PDSCH ") primary sign and the configuration information of non-zero power CSI-RS.In the time that this serving BS carries out actual schedule to this subscriber equipment, can be at descending control signaling (the Downlink control information sending to this subscriber equipment, referred to as " DCI ") in increase the PQI of 2 bits and indicate this subscriber equipment to adopt any the cover parameter in above-mentioned PQ parameter sets to carry out demodulation PDSCH, this subscriber equipment is according to this indication and other parameter, can determine which RE for carrying out transfer of data, then the data of this subscriber equipment on can these RE of demodulation.
