摘要： A method of performing channel sounding in a frequency division duplex (FDD) system in which an uplink frame and a downlink frame use different frequency bands includes dividing a transmission bandwidth with respect to the uplink frame into a plurality of sounding zones, allocating at least one of the plurality of sounding zones to a user equipment and receiving a sounding signal from the user equipment through the allocated sounding zone. Inter-cell interference can be mitigated and overhead due to transmission of the sounding signal can be reduced.

摘要： A method is described for transmitting signals in a mobile communication system which splits an information block into a plurality of split-information blocks and performs a hybrid automatic repeat request (HARQ) process upon each of the split-information blocks. A method is also described for reducing control information overhead by transmitting control information only through one control channel when splitting an information block and transmitting split-information blocks through a plurality of subframes or a plurality of resource blocks. The segmentation of the information block is performed in a physical layer to reduce medium access control (MAC) overhead and to simplify implementation.
