Power saving mechanism

1. A method comprising:

receiving, by a wireless device, a radio resource control message comprising:

a radio network temporary identifier, RNTI, for a downlink control information (DCI) used for power saving; and

a location parameter of a block, for the wireless device, in the DCI;

receiving, based on the RNTI, a first DCI comprising blocks, wherein:

the location parameter indicates a location of a first block, of the blocks, for the wireless device; and

the first block comprises:

a wake-up indication for the wireless device; and

a dormancy indication for at least one secondary cell of the wireless device;

transitioning to a wake-up state in response to the wake-up indication; and

transitioning the at least one secondary cell to a dormant state based on the dormancy indication.

2. The method of claim 1 , further comprising, while in the wake-up state, receiving a second DCI comprising at least one of:

a downlink assignment; and

an uplink grant.

3. The method of claim 1 , further comprising, while the at least one secondary cell is in the dormant state, stopping monitoring a downlink control channel on the at least one secondary cell.

4. The method of claim 3 , wherein the stopping monitoring the downlink control channel comprises stopping monitoring downlink control channels on one or more cells in a discontinuous reception active time of a discontinuous reception cycle.

5. The method of claim 1 , further comprising, while the at least one secondary cell is in the dormant state, at least one of:

stopping receiving a downlink data packet via the at least one secondary cell; and

stopping transmitting an uplink signal on the at least one secondary cell.

6. The method of claim 1 , further comprising, while the at least one secondary cell is in the dormant state, transmitting a channel state information report for the at least one secondary cell.

7. The method of claim 1 , wherein:

the radio resource control message indicates a format of the DCI used for power saving; and

the receiving the first DCI is based on:

a first format of the first DCI being the format of the DCI used for power saving; and

cyclic redundancy check bits of the first DCI being scrambled with the RNTI.

8. The method of claim 1 , wherein each of the blocks in the first DCI:

corresponds to a respective wireless device of a plurality of wireless devices; and

notifies power saving information for the respective wireless device.

9. A method comprising:

receiving, by a wireless device, a radio resource control message comprising:

a radio network temporary identifier, RNTI, for a downlink control information (DCI) used for power saving for wireless devices comprising the wireless device; and

a location parameter for the wireless device;

receiving, based on the RNTI, a first DCI comprising blocks, wherein:

the location parameter indicates a location of a block, of the blocks, for the wireless device; and

the block comprises a wake-up indication; and

transitioning, in response to the wake-up indication, to a wake-up state comprising monitoring one or more downlink control channels in a discontinuous reception active time of a discontinuous reception cycle.

10. The method of claim 9 , further comprising, while in the wake-up state, receiving a second DCI comprising at least one of:

a downlink assignment; and

an uplink grant.

11. The method of claim 9 , further comprising, while in the wake-up state, at least one of:

monitoring downlink control channels on one or more cells;

receiving downlink data packets via the one or more cells; and

transmitting uplink signals on the one or more cells.

12. The method of claim 9 , wherein:

the radio resource control message indicates a format of the DCI used for power saving; and

the receiving the first DCI is based on:

a first format of the first downlink control information DCI being the format of the DCI used for power saving; and

cyclic redundancy check bits of the first DCI being scrambled with the RNTI.

13. The method of claim 9 , wherein each of the blocks in the first DCI:

corresponds to a respective wireless device of a plurality of wireless devices; and

notifies power saving information for the respective wireless device.

14. A method comprising:

receiving, by a wireless device, a radio resource control message comprising:

a radio network temporary identifier, RNTI, for a downlink control information (DCI) used for power saving;

a location parameter for the wireless device; and

configuration parameters of one or more secondary cells;

receiving, based on the RNTI, a first DCI comprising blocks, wherein:

the location parameter indicates a location of a block, of the blocks, for the wireless device; and

the block comprises a dormancy indication for at least one secondary cell of the one or more secondary cells; and

transitioning the at least one secondary cell to a dormant state in response to the dormancy indication indicating the dormant state.

15. The method of claim 14 , further comprising, while the at least one secondary cell is in the dormant state, stopping monitoring a downlink control channel on the at least one secondary cell.

16. The method of claim 15 , wherein the stopping monitoring the downlink control channel comprises stopping monitoring downlink control channels on one or more cells in a discontinuous reception active time of a discontinuous reception cycle.

17. The method of claim 14 , further comprising, while the at least one secondary cell is in the dormant state, at least one of:

stopping receiving a downlink data packet via the at least one secondary cell; and

stopping transmitting an uplink signal on the at least one secondary cell.

18. The method of claim 14 , further comprising, while the at least one secondary cell is in the dormant state, transmitting a channel state information report for the at least one secondary cell.

19. The method of claim 14 , wherein:

the radio resource control message indicates a format of the DCI used for power saving; and

the receiving the first DCI is based on:

a first format of the first DCI being the format of the DCI used for power saving; and

cyclic redundancy check bits of the first DCI being scrambled with the RNTI.

20. The method of claim 14 , wherein each of the blocks in the first DCI:

corresponds to a respective wireless device of a plurality of wireless devices; and

notifies power saving information for the respective wireless device.
