摘要：Methods and an apparatus for performs frequency hopping in a single carrier frequency division multiple access (SC-FDMA) transmission are disclosed. The apparatus comprises means for receiving information related to a transmission allocation unit that spans at least two time based slots comprising first and second slots and a plurality of frequency sub-divisions comprising first and second frequency sub-divisions; means for determining the second frequency sub-division in the second slot based on the first frequency sub-division in the first slot and further in accordance with mirror transposition frequency hopping or cyclic shift frequency hopping, or both; and means for sending data in the first frequency sub-division of the first slot and in the second frequency sub-division of the second slot. Further disclosed is an apparatus that receives data via a single carrier frequency division multiple access (SC-FDMA) uplink channel utilizing frequency hopping, comprising means for determining a transmission allocation unit that spans at least two time based slots comprising first and second slots and a plurality of frequency sub-divisions comprising first and second frequency sub-divisions and means for receiving data sent in the first frequency sub-division of the first slot and in the second frequency sub-division of the second slot. The second frequency subdivision in the second slot is determined based on the first frequency sub-division in the first slot and further in accordance with mirror transposition frequency hopping, or cyclic shift frequency hopping, or both.
