Terminal, radio communication method, base station, and system for downlink shared channel decoding
According to an aspect of the present disclosure, a user terminal includes a receiving section that receives a downlink shared channel, and a control section that controls monitoring of the downlink shared channel in a time domain resource and a frequency domain resource of a cycle configured by higher layer signaling.
1. A terminal comprising:
a receiver that receives a physical downlink shared channel (PDSCH), which is transmitted in period configured by a higher layer parameter, and a downlink control information (DCI); and
a processor that performs a control to transmit an ACK at least when the DCI indicates deactivation of the PDSCH, and to transmit a NACK when the PDSCH is unsuccessfully decoded.
2. The terminal according to claim 1 , wherein the processor controls reception of the PDSCH based on retransmission information indicated by the DCI.
3. The terminal according to claim 1 , wherein the processor controls reception of the PDSCH based on hybrid automatic repeat request (HARQ) process number information configured by the higher layer parameter.
4. The terminal according to claim 2 , wherein the processor controls reception of the PDSCH based on hybrid automatic repeat request (HARQ) process number information configured by the higher layer parameter.
5. The terminal according to claim 1 , wherein the DCI is cyclic redundancy check (CRC) scrambled with a given identifier.
6. The terminal according to claim 2 , wherein the DCI is cyclic redundancy check (CRC) scrambled with a given identifier.
7. The terminal according to claim 3 , wherein the DCI is cyclic redundancy check (CRC) scrambled with a given identifier.
8. The terminal according to claim 1 , wherein the DCI is DCI format 1_0.
9. The terminal according to claim 2 , wherein the DCI is DCI format 1_0.
10. The terminal according to claim 3 , wherein the DCI is DCI format 1_0.
11. The terminal according to claim 5 , wherein the DCI is DCI format 1_0.
12. A radio communication method comprising:
receiving a physical downlink shared channel (PDSCH), which is transmitted in period configured by a higher layer parameter, and a downlink control information (DCI); and
performing a control to transmit an ACK at least when the DCI indicates deactivation of the PDSCH, and to transmit a NACK when the PDSCH is unsuccessfully decoded.
13. A base station comprising:
a transmitter that transmits a physical downlink shared channel (PDSCH), which is transmitted in period configured by a higher layer parameter, and a downlink control information (DCI); and
a processor that performs a control to receive an ACK at least when the DCI indicates deactivation of the PDSCH, and to receive a NACK when the PDSCH is unsuccessfully decoded by the terminal.
14. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a receiver that receives a physical downlink shared channel (PDSCH), which is transmitted in period configured by a higher layer parameter, and a downlink control information (DCI); and
a processor that performs a control to transmit an ACK at least when the DCI indicates deactivation of the PDSCH, and to transmit a NACK when the PDSCH is unsuccessfully decoded; and
the base station comprises:
a transmitter that transmits the physical downlink shared channel (PDSCH), which is transmitted in period configured by the higher layer parameter, and the downlink control information (DCI); and
a processor that performs a control to receive an ACK at least when the DCI indicates deactivation of the PDSCH, and to receive a NACK when the PDSCH is unsuccessfully decoded by the terminal.
