- Appl. No: 16/863238
- Application Filed: April 30, 2020
- Claim: 1. A method, performed by user equipment (UE), of transmitting uplink data, the method comprising: receiving, from a base station, configuration information for an uplink resource; determining a Hybrid Automatic Repeat Request (HARQ) process based on the configuration information; starting a configured grant timer (CGT) and a configured grant retransmission timer (CGRT) when uplink data corresponding to the HARQ process is transmitted; restarting the CGRT when the uplink data corresponding to the HARQ process is retransmitted; receiving, from the base station, downlink feedback information (DFI); and stopping the CGT and the CGRT based on the DFI indicating whether the base station received the uplink data.
- Claim: 2. The method of claim 1, wherein the CGT stops when the DFI indicates the base station received the uplink data.
- Claim: 3. The method of claim 1, wherein the CGRT stops when the CGT expires.
- Claim: 4. The method of claim 1, further comprising receiving, from the base station, a dynamic grant, and wherein the starting of the CGT and the CGRT comprises starting the CGT based on the dynamic grant.
- Claim: 5. User equipment (UE) for transmitting uplink data, the UE comprising: a transceiver; and at least one processor coupled to the transceiver and configured to: receive, from a base station, configuration information for an uplink resource; determine a Hybrid Automatic Repeat Request (HARQ) process based on the configuration information; control to start a configured grant timer (CGT) and a configured grant retransmission timer (CGRT) when the uplink data corresponding to the HARQ process is transmitted; control to restart the CGRT when the uplink data corresponding to the HARQ process is retransmitted; receive, from the base station, downlink feedback information (DFI); and control to stop the CGT and the CGRT based on the DFI indicating of whether the base station received the uplink data.
- Claim: 6. The UE of claim 5, wherein the CGT stops when the DFI indicates the base station received the uplink data.
- Claim: 7. The UE of claim 5, wherein the CGRT stops when the CGT expires.
- Claim: 8. The UE of claim 6, wherein the at least one processor is further configured to: receive, from the base station, a dynamic grant; and control to start the CGT based on the dynamic grant.
- Claim: 9. A method, performed by a base station, of receiving uplink data, the method comprising: transmitting, to user equipment (UE), configuration information for an uplink resource; receiving, from the UE, the uplink data corresponding to a Hybrid Automatic Repeat Request (HARQ) process, wherein the HARQ process is determined based on the configuration information; and transmitting, to the UE, downlink feedback information (DFI), wherein, based on the DFI, a configured grant timer (CGT) and a configured grant retransmission timer stop.
- Claim: 10. The method of claim 9, wherein the CGT stops when the DFI indicates the base station received the uplink data.
- Claim: 11. The method of claim 9, wherein, when the CGT expires, a configured grant retransmission timer (CGRT) stops.
- Claim: 12. The method of claim 9, further comprising: transmitting, to the UE, a dynamic grant, and wherein the CGT starts based on the dynamic grant.
- Claim: 13. A base station for transmitting uplink data, the base station comprising: a transceiver; and at least one processor coupled to the transceiver and configured to: transmit, to user equipment (UE), configuration information for an uplink resource; and receive, from the UE, the uplink data corresponding to a Hybrid Automatic Repeat Request (HARQ) process, wherein the HARQ process is determined based on the configuration information; and transmit, to the UE, downlink feedback information (DFI), wherein, based on the DFI, a configured grant timer (CGT) and a configured grant retransmission stop.
- Claim: 14. The base station of claim 13, wherein the CGT stops when the DFI indicates the base station received the uplink data.
- Claim: 15. The base station of claim 13, wherein, when the CGT expires, a configured grant retransmission timer (CGRT) stops.
- Claim: 16. The base station of claim 13, wherein the at least one processor is further configured to transmit, to the UE, a dynamic grant, and wherein the CGT starts based on the dynamic grant.
