User terminal and radio communication method

說明書
The control section 301 may determine the resources (for example, time and/or frequency resources) to use to receive SRs, based on at least one of the first TTI and the second TTI. The control section 301 may, for example, perform control so that an SR is received using a PUCCH resource in the first TTI, or perform control so that an SR is received using an sPUCCH resource in the second TTI.
The control section 301 may configure an SR in a control channel in a given TTI, for a user terminal 20. For example, the control section 301 may configure SRs only in a control channel that is used in the first TTI (for example, the PUCCH), configure SRs only in a control channel that is used in the second TTI (for example, the sPUCCH), or configure SRs in both the control channel used in the first TTI and the control channel used in the second TTI.
The control section 301 may perform control so that high layer signaling for allowing the user terminal 20 to transmit an SR to request UL resources for predetermined traffic (for example, LL traffic) by using the control channel used in the second TTI, is transmitted to the user terminal 20.
The transmission signal generation section 302 generates downlink signals (downlink control signals, downlink data signals, downlink reference signals and so on) based on commands from the control section 301, and outputs these signals to the mapping section 303. The transmission signal generation section 302 can be constituted by a signal generator, a signal generating circuit or signal generating apparatus that can be described based on general understanding of the technical field to which the present invention pertains.
