Apparatus and method for transmitting/receiving downlink data channel signal transmission information in cellular radio communication system using cooperative multi-point scheme
First Claim
1. A method for wireless communication, the method comprising:
- receiving, using at least one processor, a signaling message via higher layer signaling, the signaling message comprising first configuration information related to a plurality of starting symbols to which a physical downlink shared channel (PDSCH) is mapped;
receiving, using the at least one processor, control information for scheduling the PDSCH, the control information comprising a first information field indicating a starting symbol among the plurality of starting symbols and a second information field indicating a scrambling identity from at least two scrambling identities for a reference signal related to the PDSCH given by the signaling message; and
receiving, using the at least one processor, downlink data on the PDSCH based on the starting symbol indicated by the first information field.

Abstract
An apparatus and a method for transmitting/receiving downlink data channel signal transmission information in a cellular radio communication system using a Cooperative Multi-Point (CoMP) scheme are provided. In the downlink data channel signal transmission information transmission method, a Base Station (BS) transmits downlink data channel signal transmission information including information related to Resource Elements (REs) scheduled for a downlink data channel signal transmission to a User Equipment (UE), and transmits downlink data channel signal non-transmission information including information related to REs through which a downlink data channel signal is not transmitted among the REs scheduled for the downlink data channel signal transmission to the UE.
