    摘要: A signal mapping method and a signal transmission method applying a subcarrier shift method are described. A signal mapping method using shifted subcarriers includes shifting positions of data subcarriers by as much as a frequency band corresponding to half of spacing between data subcarriers on a frequency axis, and shifting positions of random access preamble subcarriers by as much as a frequency band corresponding to half of spacing between the data subcarriers and to a specific ratio of spacing between the random access preamble subcarriers, and mapping data and a random access preamble to the data subcarriers and the random access preamble subcarrier, respectively. Even when the spacing between the data subcarriers is a multiple of the spacing between the random access preamble subcarriers, DC distortion can be minimized.

    摘要: A method for communicating with a relay station is disclosed. The method for communicating with a relay station comprises transmitting resource allocation information of downlink traffic and uplink traffic from a base station to the relay; and transmitting the downlink traffic to the relay by encapsulating the downlink traffic in accordance with the resource allocation information and receiving encapsulated uplink traffic from the relay in accordance with the resource allocation information. It is possible to enable efficient communication through a relay using a minimum interface without deterioration of throughput even in the case that a base station does not know detailed attributes of a relay existing in a system. Also, it is possible to coordinate collision through a master relay in case of a system supporting multi-hop relays.

    摘要: A method for inserting parity into an FCH is disclosed. A method for inserting parity into a frame control header includes channel-encoding, by an additional channel encoder, a frame control header bit applied to a legacy encoder, and generating an additional codeword, and mapping the codeword generated by the legacy encoder and the additional channel encoder subcarrier mapping codeword to subcarriers. This method inserts parity into the FCH, and defines a new FCH, such that it extends an FCH coverage simultaneously while maintaining a compatibility with a legacy system. Also, it may add additional energy to a legacy FCH or may give a coding gain to the same legacy FCH, such that it can extend information transferable using reserved bits of the FCH.

    摘要: A method for establishing RACH transmission to prepare against the frequency offset is disclosed. The method reduces the length of the RACH preamble even if the frequency offset exists, allows the RACH preamble to include a repeated structure (also called an iterative structure) or to use a specific sequence with less affect on the frequency offset, so that the Node-B can easily detect the RACH preamble. If different conditions are established in a high-speed UE and a low-speed UE, an amount of system overheads can be reduced as compared to another case in which an overall RACH condition has been prescribed for only the high-speed UE irrespective of the low-speed UE. And, the method determines whether the user equipment (UE) can estimate its speed according to the aforementioned RACH setup condition, and prescribes a detailed RACH access method according to the determined result.
