Macro and micro discontinuous reception
Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).
1. An apparatus for wireless communication, comprising:
one or more processors; and
memory coupled with the one or more processors and storing instructions executable by the one or more processors to cause the apparatus to:
receive, at a user equipment (UE) during an on duration of a discontinuous reception (DRX) configuration established at the UE, a downlink (DL) reception indication that identifies an inactivity interval;
identify, at the UE based at least in part on the DL reception indication, a reception opportunity that follows the inactivity interval, wherein the reception opportunity is different than the on duration of the DRX configuration; and
monitor, by the UE, for a physical downlink control channel (PDCCH) during the reception opportunity.
2. The apparatus of claim 1 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
receive the DL reception indication in a second PDCCH during the on duration of the DRX configuration.
3. The apparatus of claim 1 , wherein:
the on duration of the DRX configuration is associated with a periodic duration of the DRX configuration; and
the reception opportunity is different than the periodic duration of the DRX configuration.
4. The apparatus of claim 1 , wherein the DL reception indication identifies a zero length inactivity interval.
5. The apparatus of claim 1 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
establish a radio resource control (RRC) connection with a network device, wherein the DRX configuration is established based at least in part on the establishment of the RRC connection with the network device.
6. An apparatus for wireless communication, comprising:
one or more processors; and
memory coupled with the one or more processors and storing instructions executable by the one or more processors to cause the apparatus to:
transmit, by a network device during an on duration of a discontinuous reception (DRX) configuration established with a user equipment (UE), a downlink (DL) reception indication to the UE that identifies an inactivity interval; and
transmit, by the network device based at least in part on the transmission of the DL reception indication, a physical downlink control channel (PDCCH) to the UE during a reception opportunity of the UE that follows the inactivity interval, wherein the reception opportunity is different than the on duration of the DRX configuration.
7. The apparatus of claim 6 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
transmit the DL reception indication in a second PDCCH during the on duration of the DRX configuration.
8. The apparatus of claim 6 , wherein:
the on duration of the DRX configuration is associated with a periodic duration of the DRX configuration; and
the reception opportunity is different than the periodic duration of the DRX configuration.
9. The apparatus of claim 6 , wherein the DL reception indication identifies a zero length inactivity interval.
10. The apparatus of claim 6 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
establish a radio resource control (RRC) connection with the UE, wherein the DRX configuration is established based at least in part on the establishment of the RRC connection with the UE.
11. A method of wireless communication, comprising:
receiving, at a user equipment (UE) during an on duration of a discontinuous reception (DRX) configuration established at the UE, a downlink (DL) reception indication that identifies an inactivity interval;
identifying, at the UE based at least in part on the DL reception indication, a reception opportunity that follows the inactivity interval, wherein the reception opportunity is different than the on duration of the DRX configuration; and
monitoring, by the UE, for a physical downlink control channel (PDCCH) during the reception opportunity.
12. The method of claim 11 , the receiving comprising:
receiving the DL reception indication in a second PDCCH during the on duration of the DRX configuration.
13. The method of claim 11 , wherein:
the on duration of the DRX configuration is associated with a periodic duration of the DRX configuration; and
the reception opportunity is different than the periodic duration of the DRX configuration.
14. The method of claim 11 , wherein the DL reception indication identifies a zero length inactivity interval.
15. The method of claim 11 , further comprising:
establishing a radio resource control (RRC) connection with a network device, wherein the DRX configuration is established based at least in part on establishing the RRC connection with the network device.
16. A method of wireless communication, comprising:
transmitting, by a network device during an on duration of a discontinuous reception (DRX) configuration established with a user equipment (UE), a downlink (DL) reception indication to the UE that identifies an inactivity interval; and
transmitting, by the network device based at least in part on transmitting the DL reception indication, a physical downlink control channel (PDCCH) to the UE during a reception opportunity of the UE that follows the inactivity interval, wherein the reception opportunity is different than the on duration of the DRX configuration.
17. The method of claim 16 , the transmitting the DL reception indication comprising:
transmitting the DL reception indication in a second PDCCH during the on duration of the DRX configuration.
18. The method of claim 16 , wherein:
the on duration of the DRX configuration is associated with a periodic duration of the DRX configuration; and
the reception opportunity is different than the periodic duration of the DRX configuration.
19. The method of claim 16 , wherein the DL reception indication identifies a zero length inactivity interval.
20. The method of claim 16 , further comprising:
establishing a radio resource control (RRC) connection with the UE, wherein the DRX configuration is established based at least in part on establishing the RRC connection with the UE.
