Abstract
Disclosed herein are a method and apparatus for transmitting/receiving an uplink signal. A user equipment transmits a first uplink channel within a first transmission time interval (TTI); transmits a second uplink channel within a second TTI; and transmits a first demodulation reference signal (DMRS) for the first uplink channel and a second DMRS for the second uplink channel on a same time symbol. The user equipment generates the first DMRS and the second DMRS based on a same TTI index.
Claims16
A method for transmitting an uplink signal by a user equipment in a wireless communication system, the method comprising:
- transmitting a first uplink channel within a first transmission time interval (TTI);
- transmitting a second uplink channel within a second TTI;
- and
- transmitting a first demodulation reference signal (DMRS) for the first uplink channel and a second DMRS for the second uplink channel in a same time symbol,
- wherein the first DMRS and the second DMRS are generated based on a same TTI index.
A user equipment for transmitting an uplink signal in a wireless communication system, the user equipment comprising:
- a radio frequency (RF) unit, and
- a processor configured to control the RF unit,
- wherein the processor is configured to:
- control the RF unit to transmit a first uplink channel within a first transmission time interval (TTI);
- control the RF unit to transmit a second uplink channel within a second TTI;
- and
- control the RF unit to transmit a first demodulation reference signal (DMRS) for the first uplink channel and a second DMRS for the second uplink channel in a same time symbol,
- wherein the processor generates the first DMRS and the second DMRS based on a same TTI index.
A method for receiving an uplink signal by a base station in a wireless communication system, the method comprising:
- receiving a first uplink channel from a user equipment within a first transmission time interval (TTI);
- receiving a second uplink channel from the user equipment within a second TTI;
- and
- receiving a first demodulation reference signal (DMRS) for the first uplink channel and a second DMRS for the second uplink channel from the user equipment in a same time symbol, wherein the first DMRS and the second DMRS are detected based on a same TTI index.
A base station for receiving an uplink signal in a wireless communication system, the base station comprising:
- a radio frequency (RF) unit, and
- a processor configured to control the RF unit,
- wherein the processor is configured to:
- control the RF unit to receive a first uplink channel from a user equipment within a first transmission time interval (TTI);
- control the RF unit to receive a second uplink channel from the user equipment within a second TTI;
- and
- control the RF unit to receive a first demodulation reference signal (DMRS) for the first uplink channel and a second DMRS for the second uplink channel from the user equipment in a same time symbol,
- wherein the processor detects the first DMRS and the second DMRS based on a same TTI index.
