Devices and methods for discontinuous reception in new radio
View Patent ↗A method, by a user equipment (UE), for discontinuous reception (DRX) operation is described. The method includes receiving, by receiving circuitry of the UE, a radio resource control (RRC) configuration containing a first DRX parameter configuration, the first DRX parameter configuration configuring a first DRX parameter having a first unit, and receiving, by the receiving circuitry of the UE, the RRC configuration containing a second DRX parameter configuration, the second DRX parameter configuration configuring a second DRX parameter having a second unit, where the first unit is in millisecond or sub-millisecond, and the second unit is in slot or symbol.
1. A method, by a user equipment (UE), for discontinuous reception (DRX) operation, the method comprising:
receiving, by receiving circuitry of the UE, a radio resource control (RRC) configuration containing a first DRX parameter configuration, the first DRX parameter configuration configuring a first DRX parameter having a first unit which has a fixed duration;
receiving, by the receiving circuitry of the UE, the RRC configuration containing a second DRX parameter configuration, the second DRX parameter configuration configuring a second DRX parameter having a second unit which has a scalable duration; and
receiving, by the receiving circuitry of the UE, a downlink control information (DCI) which indicates a transport block reception on a bandwidth part (BWP);
wherein a determination of the scalable duration of the second unit is based on a slot length of the BWP;
wherein the first unit is in millisecond, and the second unit is in slot, and the BWP is indicated by a BWP indicator contained in the DCI.
2. The method of claim 1 , wherein the slot length is determined based on subcarrier spacing.
3. The method of claim 1 , wherein at least one of the first and second DRX parameters includes a drx-onDurationTimer, a drx-ShortCycle, a drx-LongCycleStartOffset, a drx-InactivityTimer, a drx-HARQ-RTT-TimerDL, a drx-HARQ-RTT-TimerUL, a drx-RetransmissionTimerDL, or a drx-RetransmissionTimerUL.
4. A user equipment (UE) comprising:
receiving circuitry configured to:
receive a radio resource control (RRC) configuration containing a first DRX parameter configuration, the first DRX parameter configuration configuring a first DRX parameter having a first unit which has a fixed duration;
receive the RRC configuration containing a second DRX parameter configuration, the second DRX parameter configuration configuring a second DRX parameter having a second unit which has a scalable duration; and
receive a downlink control information (DCI) which indicates a transport block reception on a bandwidth part (BWP);
wherein a determination of the scalable duration of the second unit is based on a slot length of the BWP;
wherein the first unit is in millisecond, and the second unit is in slot, and the BWP is indicated by a BWP indicator contained in the DCI.
5. The UE of claim 4 , wherein the slot length is determined based on subcarrier spacing.
6. The UE of claim 4 , wherein at least one of the first and second DRX parameters includes a drx-onDurationTimer, a drx-ShortCycle, a drx-LongCycleStartOffset, a drx-InactivityTimer, a drx-HARQ-RTT-TimerDL, a drx-HARQ-RTT-TimerUL, a drx-RetransmissionTimerDL, or a drx-RetransmissionTimerUL.
7. A method for providing discontinuous reception (DRX) operation by a base station, the method comprising:
providing, by transmitting circuitry of the base station, a radio resource control (RRC) configuration containing a first DRX parameter configuration, the first DRX parameter configuration configuring a first DRX parameter having a first unit which has a fixed duration;
providing, by the transmitting circuitry of the base station, the RRC configuration containing a second DRX parameter configuration, the second DRX parameter configuration configuring a second DRX parameter having a second unit which has a scalable duration; and
providing, by the transmitting circuitry of the base station, a downlink control information (DCI) which indicates a transport block reception on a bandwidth part (BWP);
wherein a determination of the scalable duration of the second unit is based on a slot length of the BWP;
wherein the first unit is in millisecond, and the second unit is in slot, and the BWP is indicated by a BWP indicator contained in the DCI.
8. The method of claim 7 , wherein the slot length is determined based on subcarrier spacing.
9. The method of claim 7 , wherein at least one of the first and second DRX parameters includes a drx-onDurationTimer, a drx-ShortCycle, a drx-LongCycleStartOffset, a drx-InactivityTimer, a drx-HARQ-RTT-TimerDL, a drx-HARQ-RTT-TimerUL, a drx-RetransmissionTimerDL, or a drx-RetransmissionTimerUL.
