and transmitting the first channel signal at a predetermined time after the transmission of the second channel signal is started. ### Claim 2 (depends on 1) The method according to claim 1, wherein the second channel signal is transmitted through a dedicated physical control channel (DPCCH), and the first channel signal is transmitted through one of an enhanced-dedicated channel (E-DCH) and a high speed-dedicated physical control channel (HS-DPCCH). ### Claim 3 (depends on 1) The method according to claim 1, wherein the first channel signal and the second channel signal are multiplexed using different codes. ### Claim 4 (depends on 1) The method according to claim 1, wherein each of the first channel signal and the second channel signal includes a DTX interval in which no signal is transmitted according to the DTX scheme. ### Claim 5 A user equipment (UE) for transmitting channel signals in a mobile communication system using a compressed mode transmission scheme and a discontinuous transmission (DTX) scheme, the UE comprising: if a transmission interval of one of a preamble and a postamble of a second channel signal partially overlaps a compressed mode gap, means for transmitting the second channel signal in a remaining transmission interval excluding the preamble or the postamble which is partially overlapped with the compressed mode gap, wherein the second channel signal includes information used for detecting a first channel signal and the compressed mode gap is an interval in which the channel signals are not transmitted according to the compressed mode transmission scheme; and means for transmitting the first channel signal at a predetermined time after the transmission of the second channel signal is started. ### Claim 6 (depends on 5) The user equipment according to claim 5, wherein the second channel signal is transmitted through a dedicated physical control channel (DPCCH), and the first channel signal is transmitted through one of an enhanced-dedicated channel (E-DCH) and a high speed-dedicated physical control channel (HS-DPCCH). ### Claim 7 (depends on 5) The user equipment according to claim 5, wherein each of the first channel signal and the second channel signal includes a DTX interval in which no signal is transmitted according to the DTX scheme. ### Claim 8 (depends on 5) The user equipment according to claim 5, wherein the first channel signal and the second channel signal are multiplexed using different codes. ### Claim 9 A method for receiving channel signals in a mobile communication system using a compressed mode transmission scheme and a discontinuous transmission (DTX) scheme, the method comprising: if a transmission interval of one of a preamble and a postamble of a second channel signal partially overlaps a compressed mode gap, receiving, by an e-Node B (eNB), the second channel signal in a remaining transmission interval excluding the preamble or the postamble which is partially overlapped with the compressed mode gap, wherein the second channel signal includes information used for detecting a first channel signal and the compressed mode gap is an interval in which the channel signals are not transmitted according to the compressed mode transmission scheme; and receiving, by the eNB, the first channel signal at a predetermined time after the transmission of the second channel signal is started. ### Claim 10 (depends on 9) The method according to claim 9, wherein the second channel signal is transmitted through a dedicated physical control channel (DPCCH), and the first channel signal is transmitted through one of an enhanced- dedicated channel (E-DCH) and a high speed-dedicated physical control channel (HS-DPCCH). ### Claim 11 (depends on 9) The method according to claim 9, wherein the first channel signal and the second channel signal are multiplexed using different codes. ### Claim 12 (depends on 9) The method according to claim 9, wherein each of the first channel signal and the second channel signal includes a DTX interval in which signal is transmitted according to the DTX scheme. ### Claim 13 An e-Node B (eNB) for receiving channel signals in a mobile communication system using a compressed mode transmission scheme and a discontinuous transmission (DTX) scheme, the eNB comprising: if a transmission interval of one of a preamble and a postamble of a second channel signal partially overlaps a compressed mode gap, means for receiving the second channel signal in a remaining transmission interval excluding the preamble or the postamble which is partially overlapped with the compressed mode gap, wherein the second channel signal includes information used for detecting a first channel signal and the compressed mode gap is an interval in which the channel signals are not transmitted according to the compressed mode transmission scheme; and means for receiving the first channel signal at a predetermined time after the transmission of the second channel signal is started. ### Claim 14 (depends on 13) The eNB according to claim 13, wherein the second channel signal is transmitted through a dedicated physical control channel (DPCCH), and the first channel signal is transmitted through one of an enhanced-dedicated channel (E-DCH) and a high speed-dedicated physical control channel (HS-DPCCH). ### Claim 15 (depends on 13) The eNB according to claim 13, wherein the first channel signal and the second channel signal are multiplexed using different codes. ### Claim 16 (depends on 13) The eNB according to claim 13, wherein each of the first channel signal and the second channel signal includes a DTX interval in which no signal is transmitted according to the DTX scheme.
