Abstract
The present invention is designed so that communication is performed properly when contention-based UL transmission is used. A user terminal has a transmission section that transmits a first reference signal and a UL data signal, without a UL transmission indication from a radio base station, and a control section that controls generation of the first reference signal by using code resource associated with the user terminal, and the control section controls generation of the first reference signal by using more code resources than code resources that can be used for a second reference signal that is transmitted with the UL data signal in response to the UL transmission indication.
Claims12
A user terminal comprising:
- a transmission section that transmits a first reference signal and a UL data signal, without a UL transmission indication from a radio base station;
- and
- a control section that controls generation of the first reference signal by using code resource associated with the user terminal,
- wherein the control section controls generation of the first reference signal by using more code resources than code resources that can be used for a second reference signal that is transmitted with the UL data signal in response to the UL transmission indication.
A radio communication method for a user terminal, comprising the steps of:
- generating a first reference signal by using code resource associated with the user terminal;
- and
- transmitting a first reference signal and a UL data signal, without a UL transmission indication from a radio base station,
- wherein the user terminal controls generation of the first reference signal by using more code resources than code resources that can be used for a second reference signal that is transmitted with the UL data signal in response to the UL transmission indication.
