Abstract
A method for a user equipment (UE) monitoring a physical downlink control channel (PDCCH) for power saving signaling is disclosed. The method comprises receiving a discontinuous reception (DRX) configuration from a base station (BS) to configure the UE to monitor a scheduling signal on the PDCCH within a DRX active time, and receiving a configuration from the BS to configure the UE to monitor the power saving signaling on the PDCCH and instructing the UE to wake up for monitoring the scheduling signal in the DRX active time, wherein the configuration includes a time in milliseconds prior to a start of a DRX on-duration time, and instructs the UE to start monitoring the PDCCH for the power saving signaling.

Claim
1. A method for a user equipment (UE) monitoring a physical downlink control channel (PDCCH) for power saving signaling, the method comprising:
receiving a discontinuous reception (DRX) configuration from a base station (BS) to configure the UE to monitor a scheduling signal on the PDCCH within a DRX active time; and receiving a configuration from the BS to configure the UE to monitor the power saving signaling on the PDCCH and instructing the UE to wake up for monitoring the scheduling signal in the DRX active time, wherein the configuration includes a time in milliseconds prior to a start of a DRX on-duration time, and instructs the UE to start monitoring the PDCCH for the power saving signaling.
2. The method of claim 1, further comprising reporting a required time to the BS, wherein:
the required time is a number of slots prior to the start of the DRX on-duration time; and the UE is not required to monitor the PDCCH for the power-saving signaling during the number of slots.
3. The method of claim 2, wherein the required time is reported to the BS through a UE capability report.
4. The method of claim 1, wherein the DRX active time includes a DRX on-duration timer, a DRX inactivity timer, a DRX retransmission timer, a random access contention resolution timer, a random access response window that is running, a scheduling request that is sent on a Physical Uplink Control Channel (PUCCH) and is pending, or a PDCCH indicating a new transmission addressed to a Cell Radio Network Temporary Identifier (C-RNTI) of a Medium Access Control (MAC) entity that has not been received after successful reception of a random access response for a random access preamble not selected by the MAC entity among contention-based random access preambles.
5. The method of claim 1, wherein the time in milliseconds is an offset between a starting symbol of the DRX on-duration time and a starting symbol of the power saving signaling.
6. The method of claim 1, further comprising not monitoring the PDCCH for the power saving signaling when a first duration of monitoring the power saving signaling overlaps a second duration of a configured measurement gap.
7. The method of claim 6, further comprising waking up to monitor the PDCCH for the scheduling signal on an upcoming DRX active time when the UE does not detect the power saving signaling during the measurement gap.
8. The method of claim 1, wherein the DRX on-duration time includes a time while a DRX on-duration timer is running.
9. A user equipment (UE) for monitoring a physical downlink control channel (PDCCH) for power saving signaling, the UE comprising:
a processor, for executing computer-executable instructions; and a non-transitory machine-readable medium, coupled to the processor, for storing the computer-executable instructions, wherein the computer-executable instructions instruct the processor to: receive a discontinuous reception (DRX) configuration from a base station (BS) to configure the UE to monitor a scheduling signal on the PDCCH within a DRX active time; and receive a configuration from the BS to configure the UE to monitor the power saving signaling on the PDCCH and instructing the UE to wake up for monitoring the scheduling signal in the DRX active time, wherein the configuration includes a time in milliseconds prior to a start of a DRX on-duration time, and instructs the UE to start monitoring the PDCCH for the power saving signaling.
10. The UE of claim 1, wherein the computer-executable instructions further instruct the processor to report a required time to the BS, wherein:
the required time is a number of slots prior to the start of the DRX on-duration time; and the UE is not required to monitor the PDCCH for the power saving signaling during the number of slots.
11. The UE of claim 10, wherein the computer-executable instructions instruct the processor to report the required time to the through BS a UE capability report.
12. The UE of claim 9, wherein the DRX active time includes a DRX on-duration timer, a DRX inactivity timer, a DRX retransmission timer, a random access contention resolution timer, a random access response window that is running, a scheduling request that is sent on a Physical Uplink Control Channel (PUCCH) and is pending, or a PDCCH indicating a new transmission addressed to a Cell Radio Network Temporary Identifier (C-RNTI) of a Medium Access Control (MAC) entity that has not been received after successful reception of a random access response for a random access preamble not selected by the MAC entity among contention-based random access preambles.
13. The UE of claim 9, wherein the time in milliseconds is an offset between a starting symbol of the DRX on-duration time and a starting symbol of the power saving signaling.
14. The UE of claim 9, wherein the computer-executable instructions further instruct the processor to not monitor the PDCCH for the power saving signaling when a first duration of monitoring the power saving signaling overlaps a second duration of a configured measurement gap.
15. The UE of claim 14, wherein the computer-executable instructions further instruct the processor to wake up to monitor the PDCCH for the scheduling signal on an upcoming DRX active time when the UE does not detect the power saving signaling during the measurement gap.
16. The UE of claim 9, wherein the DRX on-duration time includes a time while a DRX on-duration timer is running.
