    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 method for processing data in a wireless communication system is provided. The method includes receiving a first uplink scheduling command indicating a first radio resource, receiving a second uplink scheduling command indicating a second radio resource through a random access response, and stopping a procedure associated with the second uplink scheduling command when the first radio resource and the second radio resource collide.

    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 for reducing retransmission overhead in a system based on the asynchronous channel-adaptive retransmission scheme is disclosed. If the possibility of performing data retransmission is high, the system provides a method for transmitting synchronous duration (SD) information. According to the method for transmitting the SD information, the system does not transmit scheduling information whenever receiving a retransmission request, and synchronously transmits data during a predetermined synchronous duration. Namely, the data can be retransmitted without using the scheduling information.
