    摘要： A method of performing hybrid automatic repeat request (HARQ) performed by a user equipment (UE) in a wireless communication system is provided. The method includes receiving downlink assignments in a first subframe, a downlink assignment being transmitted based on a control channel element (CCE), the CCE being a logically indexed resource unit, receiving downlink data on a downlink shared channel in the first subframe, the downlink shared channel being assigned according to the downlink assignments, generating ACK/NACK signals which indicate successful or unsuccessful reception of the downlink data, and transmitting in a second subframe, the ACK/NACK signals by using uplink resources of a subset, the subset being mapped to the first subframe, at least one of the uplink resources being mapped to a plurality of CCEs in the first subframe. Limited resources for uplink feedback are effectively used to support HARQ operation.

    摘要： A frequency hopping pattern and a method for transmitting uplink signals using the same are disclosed. A frequency hopping pattern is defined by combination of subband hopping, which is performed over one or more subbands divided from a system band for transmission of the uplink signals, and mirroring where resource blocks within one subband are arranged reversely based on the center of the subband. Sequences as to whether to apply minoring and subband hopping amount are cell-specific random numbers, and are generated independently or in combination.

    摘要： 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.

    摘要： A method of performing HARQ performed by a user equipment (UE) is provided. The method includes receiving a bundling indicator which indicates the number of bundled downlink subframes, determining whether at least one bundled downlink subframe is missed by comparing the bundling indicator with the number of detected bundled downlink subframes, generating a representative ACK/NACK signal when no bundled downlink subframe is missed, and transmitting the representative ACK/NACK signal on an uplink channel. Recovery capability is maximized and the packet loss is reduced in such a situation that less number of ACK/NACK signals are fed back than that of downlink packets.
