User terminal, radio base station and radio communication method based upon downlink control in current subframe
The present invention is designed so that adequate communication can be carried out even in future radio communication systems. A user terminal communicates using a transmission time interval (TTI), which has a predetermined TTI duration, and has a receiving section that receives a DL signal, a transmission section that transmits a UL signal, and a control section that controls at least one of transmission of a random access preamble, transmission of an SRS, reception of a broadcast channel and reception of a mobility reference signal, based on downlink control information that is included in the same TTI.
1. A terminal comprising:
a receiver that receives downlink control information that is used for scheduling of a downlink shared channel; and
a processor that determines an assignment symbol location of the downlink shared channel based on the downlink control information, and a transmission timing of a delivery acknowledgement signal for the downlink shared channel based on the downlink control information,
wherein reception of the downlink control information and transmission of the delivery acknowledgement signal are allowed within a slot.
2. The terminal according to claim 1 , wherein the processor determines a symbol location of an uplink control channel used for transmission of the delivery acknowledgement signal based on the downlink control information.
3. A terminal comprising:
a receiver that receives downlink control information including information about channel state information (CSI); and
a processor that determines assignment of a CSI reference signal based on the downlink control information, and a transmission timing of the CSI based on the downlink control information.
4. The terminal according to claim 3 , wherein the processor determines a symbol location of an uplink control channel that is used for transmission of the CSI based on the downlink control information.
5. A radio communication method for a terminal, comprising:
receiving downlink control information that is used for scheduling of a downlink shared channel; and
determining an assignment symbol location of the downlink shared channel based on the downlink control information, and a transmission timing of a delivery acknowledgement signal for the downlink shared channel based on the downlink control information,
wherein reception of the downlink control information and transmission of the delivery acknowledgement signal are allowed within a slot.
6. A radio communication method for a terminal, comprising:
receiving downlink control information including information about channel state information (CSI); and
determining assignment of a CSI reference signal based on the downlink control information, and a transmission timing of the CSI based on the downlink control information.
7. A base station comprising:
a transmitter that transmits downlink control information that is used for scheduling of a downlink shared channel; and
a processor that controls to indicate an assignment symbol location of the downlink shared channel by using the downlink control information, and a reception timing of a delivery acknowledgement signal for the downlink shared channel by using the downlink control information,
wherein transmission of the downlink control information and reception of the delivery acknowledgement signal are allowed within a slot.
8. A base station comprising:
a transmitter that transmits downlink control information including information about channel state information (CSI); and
a processor that controls to indicate an assignment of a CSI reference signal by using the downlink control information, and a reception timing of the CSI by using the downlink control information.
