Medium access control (MAC) control element for updating configurations for periodic patterns

1. A method of wireless communication, by a user equipment (UE), comprising:

receiving a periodic pattern configuration to enable communication with a base station for sending and/or receiving periodic traffic in accordance with the periodic pattern, the configuration comprising a period and an offset within the period;

receiving, from the base station, a medium access control-control element (MAC-CE) including an offset change command; and

adjusting the offset within the period based on the offset change command.

2. The method of claim 1 , further comprising receiving the offset change command in response to an arrival time of data misaligning with the periodic pattern.

3. The method of claim 1 , further comprising transmitting a request for the offset change command, the request including a suggested offset amount and the periodic pattern to which the offset change applies.

4. The method of claim 1 , in which a value of the offset change command is consistent with a direction of a slot.

5. The method of claim 4 , further comprising receiving a configuration including a downlink offset list and an uplink offset list.

6. The method of claim 5 , in which the downlink offset list includes a first list of absolute values of offsets, and the uplink offset list includes a second list of absolute values of offsets.

7. The method of claim 5 , in which the downlink offset list includes a first list of offset shift values, and the uplink offset list includes a second list of offset shift values.

8. The method of claim 5 , in which the offset change command comprises an index into the downlink offset list or the uplink offset list.

9. The method of claim 5 , further comprising transmitting a request for the offset change command, the request including an index into the downlink offset list or the uplink offset list.

10. The method of claim 1 , further comprising synchronizing, with the base station, application of the offset within the periodic pattern based on a slot during which an acknowledgment message is transmitted or received.

11. The method of claim 10 , in which the offset change command includes a reset code point.

12. The method of claim 1 , further comprising forbidding a transmission of a request for the offset change command until a prohibit timer expires.

13. The method of claim 12 , further comprising receiving an indication to disable the prohibit timer.

14. The method of claim 1 , further comprising:

receiving, from the base station, a set of radio resources via radio resource control (RRC) signaling; and

receiving, via the MAC-CE, an indication to activate one of the sets of radio resources.

15. The method of claim 14 , in which the set of radio resources comprises a plurality of sets, one set for each of a plurality of channels.

16. A method of wireless communication, by a base station, comprising:

configuring a user equipment (UE) with a periodic pattern to enable sending and/or receiving periodic traffic in accordance with the periodic pattern, wherein configuring the UE with the periodic pattern includes configuring the UE with a period and with an offset within the period;

detecting a misalignment between an arrival time of data of the periodic traffic relative to the periodic pattern; and

transmitting, to the UE, a medium access control-control element (MAC-CE) including an offset change command to adjust the offset within the period based on the misalignment.

17. The method of claim 16 , further comprising receiving, from the UE, a request for the offset change command, the request indicating the misalignment.

18. The method of claim 17 , in which the request includes a suggested offset amount and the periodic pattern to which the offset change applies.

19. The method of claim 16 , in which a value of the offset change command is consistent with a direction of a slot.

20. The method of claim 19 , further comprising transmitting, to the UE, a configuration including a downlink offset list and an uplink offset list.

21. The method of claim 20 , in which the downlink offset list includes a first list of absolute values of offsets, and the uplink offset list includes a second list of absolute values of offsets.

22. The method of claim 20 , in which the downlink offset list includes a first list of offset shift values, and the uplink offset list includes a second list of offset shift values.

23. The method of claim 20 , in which the offset change command comprises an index into the downlink offset list or the uplink offset list.

24. The method of claim 20 , further comprising receiving a request for the offset change command, the request including an index into the downlink offset list or the uplink offset list.

25. The method of claim 16 , further comprising synchronizing, with the UE, adjustment of the offset within the periodic pattern based on a slot during which an acknowledgment message is transmitted or received.

26. The method of claim 25 , in which the offset change command includes a reset code point.

27. The method of claim 16 , further comprising forbidding a transmission of a request for the offset change command until a prohibit timer expires.

28. The method of claim 27 , further comprising transmitting an indication to disable the prohibit timer.

29. The method of claim 16 , further comprising:

transmitting, to the UE, a set of radio resources via radio resource control (RRC) signaling, the set of radio resources comprising a plurality of sets, one set for each of a plurality of channels; and

transmitting, via the MAC-CE, an indication to activate one of the set of radio resources.

30. An apparatus of a UE for wireless communication, comprising:

a memory; and

at least one processor coupled to the memory and configured:

to receive a periodic pattern configuration to enable communication with a base station for sending and/or receiving periodic traffic in accordance with the periodic pattern, the configuration comprising a period and an offset within the period;

to receive, from the base station, a medium access control-control element (MAC-CE) including an offset change command; and

to adjust the offset within the period based on the offset change command.
