Abstract
In a mobile communication system using both a discontinuous transmission scheme and a compressed mode transmission scheme, if a preamble and/or a postamble of a channel including control information for transmitting a specific channel overlaps a compressed mode (CM) gap, an overall transmission unit is not transmitted or remaining signals of the transmission unit excluding the preamble and/or the postamble overlapping the CM gap are transmitted.
Claims16
A method for transmitting 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, 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
- transmitting the first channel signal at a predetermined time after the transmission of the second channel signal is started.
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.
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.
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.
