Method and apparatus for receiving downlink signals

摘要

The present invention relates to a method and apparatus for receiving downlink signals in a wireless communication system. More specifically, the present invention relates to a method for receiving downlink signals in a wireless communication and an apparatus incorporating the same, wherein the method comprises the steps of: receiving a sub frame having two slots; blind decoding a plurality of R-PDCCH (Relay Physical Downlink Control Channel) candidates in order to receive control data from the search space of a first slot; and determining whether the R-PDCCH conveys control data for downlink transmission or uplink transmission when R-PDCCH was detected in the search space, wherein the control data for the downlink transmission and uplink transmission have an equal size of data.

1. A method for receiving a downlink signal in a wireless communication system, the method comprising:
receiving a subframe including two slots; performing blind decoding (BD) of a plurality of Relay Physical Downlink Control Channel (R-PDCCH) candidates so as to receive control information in a search space of a first slot; and if the R-PDCCH is detected in the search space, determining whether the R-PDCCH carries either control information for downlink transmission or control information for uplink transmission based on which Radio Network Temporary Identifier (RNTI) is masked to a Cyclic Redundancy Check (CRC) of the R-PDCCH, wherein a RNTI allocated for the control information for downlink transmission is different from a RNTI allocated for the control information for uplink transmission, and wherein the control information for downlink transmission is the same size as the control information for uplink transmission.
