Methods and apparatuses for UE grouping

1. A user equipment (UE), comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the UE to:

receive parameters on service information and grouping rule information; and

compute a group identifier based on the received parameters on service information and the grouping rule information, wherein the service information is at least one of paging probability information and mobility information, and wherein the group identifier is computed using the at least one paging probability information and a number of groups, and the group identifier corresponds to a group wake-up-signal (WUS).

2. The UE of claim 1 , wherein the mobility information implicitly or explicitly indicates whether the UE is stationary or mobile.

3. The UE of claim 2 , wherein the mobility information implicitly or explicitly indicates whether the UE is stationary or mobile relative to a base station or a specific cell of the base station.

4. A base station, comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the base station to:

determine grouping rule information; and

transmit the grouping rule information to configure a user equipment (UE) to compute a group identifier based on parameters on service information and the grouping rule information, wherein the service information is at least one of paging probability information and mobility information, and wherein the group identifier is computed using the at least one paging probability information and a number of groups, and the group identifier corresponds to a group wake-up-signal (WUS).

5. The base station of claim 4 , wherein the mobility information implicitly or explicitly indicates whether the UE is stationary or mobile.

6. The base station of claim 5 , wherein the mobility information implicitly or explicitly indicates whether the UE is stationary or mobile relative to the base station or a specific cell of the base station.

7. The base station of claim 4 , wherein the at least one processor is configured to cause the base station to receive, from a core network node, the parameters on service information.

8. The base station of claim 7 , wherein UE mobility information is received.

9. A core network node, comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the core network node to:

determine parameters on service information; and

transmit:

the parameters on service information to trigger a user equipment (UE) to compute a group identifier based on the parameters on service information and grouping rule information, wherein the service information is at least one of paging probability information and mobility information, and wherein the group identifier is computed using the at least one paging probability information and a number of groups, and the group identifier corresponds to a group wake-up-signal (WUS); and

parameters on service information to a base station.

10. The core network node of claim 9 , wherein the grouping rule information is associated with time.

11. The core network node of claim 9 , wherein the paging probability information indicates whether the paging probability is predictable or unpredictable.

12. The core network node of claim 11 , wherein the paging probability information is paging probability information associated to time information.

13. The core network node of claim 12 , wherein the paging probability information associated to time information is paging pattern based on time, or paging probability with timer, or paging probability with time range, or paging probability with enable or disable indication, or a combination thereof.

14. The core network node of claim 9 , wherein the mobility information implicitly or explicitly indicates whether the UE is stationary or mobile.

15. The core network node of claim 14 , wherein the mobility information implicitly or explicitly indicates whether the UE is stationary or mobile relative to the base station or a specific cell of the base station.

16. The core network node of claim 14 , wherein the mobility information is mobility information associated with time information.

17. A method performed by a user equipment (UE), the method comprising:

receiving parameters on service information and grouping rule information; and

computing a group identifier based on the received parameters of service information and the grouping rule information, wherein the service information is at least one of paging probability information and mobility information, and wherein the group identifier is computed using the at least one paging probability information and a number of groups, and the group identifier corresponds to a group wake-up-signal (WUS).
