Apparatus for transmitting and receiving control information and system information for repeaters and method thereof

摘要

The present invention provides an apparatus for transmitting and receiving control information and system information for repeaters and a method thereof. According to the present invention, a base station apparatus is provided for transmitting control information for repeaters, wherein a transmitter transmits, to each repeater, interleaving mode information and information on resource areas in which R-PDCCHs (Relay-Physical Downlink Control Channel) of each repeater are allocated. The information on the resource areas includes the control information for each repeater, and the interleaving mode information is related to the interleaving modes which are applied to the R-PDCCHs that are allocated to each repeater. Furthermore, a processor performs a control operation so that among the R-PDCCHs of each repeater, and R-PDCCH of a first repeater can be allocated with an R-PDCCH of another repeater at a first interleaving mode in a first resource area and an R-PDCCH of a second repeater can be allocated at a second interleaving mode in a second resource area.

1. A method of transmitting control information for a relay node (RN) from an eNode B in a wireless communication system, the method comprising:
transmitting, by the eNode B to the RN, information on a resource region of a relay-physical downlink control channel (R-PDCCH), the transmitted information including the control information for the RN; transmitting, by the eNode B to the RN, interleaving mode information indicating an interleaving mode applied to the R-PDCCH, wherein the resource region of the R-PDCCH is specifically configured for the RN, and wherein the interleaving mode information further indicates whether the R-PDCCH is transmitted without being interleaved with at least one other R-PDCCH in a physical resource block (PRB) corresponding to the resource region; and transmitting, by the eNode B to the RN, the R-PDCCH and the at least one other R-PDCCH on the PRB based on the indicated interleaving mode, wherein a transmission start orthogonal frequency division multiplexing (OFDM) symbol index of the R-PDCCH is fixed as an OFDM symbol index 3 in the PRB, and wherein the R-PDCCH is transmitted from an OFDM symbol corresponding to the OFDM symbol index 3 in the PRB.
