Apparatus and method for transmitting/receiving downlink data channel signal transmission information in cellular radio communication cooperative multi-point scheme
First Claim
1. A method by a user equipment (UE) for wireless communication, the method comprising:
- receiving, by the UE, configuration information comprising first information related to resources being not available for a physical downlink shared channel (PDSCH) in a serving cell;
receiving, by the UE, a signaling message comprising second information indicating a plurality of starting symbols related to the PDSCH;
receiving, by the UE, 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
receiving, by the UE, downlink data on resources of the PDSCH based on the starting symbol indicated by the first information field,wherein the resources of the PDSCH are determined based on the first information in the configuration information, and the starting symbol is identified based on the second information in the signaling message and the first information field in the control information.

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.
