Method and device for transmitting and receiving data in wireless communication system

摘要

The present invention relates to a method and device for transmitting and receiving data in a wireless communication system. Specifically, the method comprises: a step in which a relay node receives a relay physical downlink control channel (R-PDCCH) including indication information relating to at least one piece of information about a second antenna port and a second scramble ID from a base station by using information about a first antenna port and a first scramble ID; and a step in which the relay node receives a downlink data channel from the base station, wherein the downlink data channel comprises a first downlink data channel region assigned to a portion of a resource block pair to which the relay physical downlink control channel is assigned, and a second downlink data channel region assigned to the other portion of the resource block pair to which the relay physical downlink control channel is assigned, wherein the first downlink data channel region is received using the first antenna and the first scramble ID, and the second downlink data channel region is received using the indication information.

1. A method of receiving data at a relay node in a wireless communication system supporting a Multi User-Multiple Input Multiple Output (Multi User-MIMO) antenna scheme, the method comprising:
receiving, by the relay node, a relay physical downlink control channel (R-PDCCH) from a base station using a first antenna port information and a first scramble identity (SCID) via a resource block (RB) pair, wherein the R-PDCCH comprises information related to at least one of a second antenna port information and a second SCID; and receiving, by the relay node, a downlink data channel from the base station using the R-PDCCH, wherein the downlink data is received using the first antenna port and the first SCID if a region in which the downlink data is received is assigned to a part of a RB bundle applied a precoding identical to a precoding applied to the RB pair via which the R-PDCCH is received, and wherein the downlink data is received using the second antenna port and the second SCID indicated by the R-PDCCH if the region is assigned to a part of a RB bundle applied a precoding different from the precoding applied to the RB pair via which the R-PDCCH is received.
