A method of generating a sub-packet in consideration of an offset is disclosed. A method of generating a sub-packet in consideration of an offset, for re-transmission of a packet from systematic bits and parity bits stored in a circular buffer includes turbo-coding an input bitstream at a predetermined code rate and generating and storing the systematic bits and the parity bits in the circular buffer, and deciding a starting position of the sub-packet in the circular buffer in consideration of the offset for puncturing at least a portion of the systematic bits of the circular buffer. Accordingly, it is possible to efficiently decide the starting position of the sub-packet to be transmitted adaptively with respect to a variable packet length, improving a coding gain, reducing complexity and reducing a calculation amount.

A method for transmitting a downlink control channel in a mobile communication system and a method for mapping the control channel to physical resources using a block interleaver are provided. In order to transmit a downlink control channel in a mobile communication system, information bits are modulated to generate one or more modulation symbols according to a specific modulation scheme, the modulation symbols are interleaved using a block interleaver, and the interleaved modulated symbols are mapped to resource elements allocated for transmission of at least one control channel in a subframe, thereby transmitting the at least one control channel.

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus in which a base station transmits a signal to a relay in a wireless communication system. A method in which a terminal receives a downlink signal in a wireless communication system that supports carrier aggregation comprises: a step of receiving, on a first carrier, a physical downlink control channel (PDCCH) having no carrier indication information; and a step of receiving a physical downlink shared channel (PDSCH) using the scheduling information carried on the PDCCH, wherein the PDSCH is received on the first carrier in the event the PDCCH is a non-semi-persistent scheduling (SPS) PDCCH, and the PDSCH is received on a second carrier different from the first carrier in the event the PDCCH is an SPS PDCCH.

A data transmission method and device are provided in a wireless communication system. A user equipment transmits uplink control information (UCI) using a physical uplink control channel (PUCCH) resource, allocated to a first component carrier (CC) among a plurality of CC's, in a sounding reference signal (SRS) subframe. The plurality of CC's in said SRS subframe, includes a second CC which comprises a single carrier-frequency division multiple access (SRS SC-FDMA) symbol, which is reserved to transmit SRS.
