Abstract

A device, system and method for a user equipment (UE) to report a network resource and capability state to a network for coordinating network resource allocations. The UE is configured to establish a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured to establish a second connection to a second network based on a second SIM of the UE. The method includes determining an upcoming first change of a state of the UE with respect to the first connection and transmitting, to the first network, an indication of the first change of state of the UE. The method further includes changing the state of the UE with respect to the first connection.

First claim

The invention claimed is:

1. A method, comprising:
at a user equipment (UE) configured with a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured with a second connection to a second network based on a second SIM of the UE:
determining an upcoming first change of a state of the UE with respect to the first connection;
generating, for transmission to the first network, a radio resource control (RRC) message including an indication of the first change of state of the UE and multiple tune-away patterns, the multiple tune-away patterns comprising at least one semi-static tune-away pattern and at least one dynamic tune-away pattern; and
changing the state of the UE with respect to the first connection.

2. The method of claim 1 , wherein the generating for transmission occurs prior to the first change of state.

3. The method of claim 1 , wherein the first change of state comprises changing a capability of the UE with respect to the first connection.

4. The method of claim 3 , wherein the changing the capability comprises one of tuning all receive chains of the UE from the first connection to the second connection, tuning some of the receive chains of the UE from the first connection to the second connection, turning off all of the receive chains of the UE, or turning off some of the receive chains of the UE.

5. The method of claim 4 , further comprising:
after the first change of state, determining an upcoming second change of state of the UE with respect to the first connection; and
generating, for transmission to the first network, an indication of the second change of state of the UE.

6. The method of claim 5 , wherein the indication of the first change of state comprises a suspend signal and the indication of the second change of state comprises a resume signal.

7. The method of claim 6 , further comprising:
when a duration between the suspend signal and the resume signal is greater than a predetermined threshold, sending a channel state indication (CSI) report after the second change of state, wherein the first network determines the duration and allocates a CSI resource for the UE to send the CSI report.

8. The method of claim 1 , further comprising:
determining a duration of the state corresponding to the first change of state, wherein the transmitted indication of the first change of state comprises a wakeup sounding reference signal (SRS) signal requesting the network allocates a CSI resource.

9. The method of claim 1 , wherein the indication of the first change of state is transmitted on a RRC layer.

10. The method of claim 1 , wherein the indication of the first change of state comprises i) one of a limited or suspended state, ii) a state duration, iii) a duty cycle of the state, and iv) a state enter and exit timing.

11. The method of claim 1 , further comprising:
Collecting state statistics for a predetermined duration, wherein the indication of the first change of state is transmitted after the predetermined duration.

12. The method of claim 1 , wherein the first network and the second network comprise a same network.

13. The method of claim 1 , wherein the first network and the second network comprise one of the same network or different networks.

14. A user equipment (UE), comprising:
a transceiver configured with a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured with a second connection to a second network based on a second SIM of the UE; and
a processor configured to:
determine an upcoming first change of a state of the UE with respect to the first connection;
generate, for transmission to the first network, a radio resource control (RRC) message including an indication of the first change of state of the UE and multiple tune-away patterns, the multiple tune-away patterns comprising at least one semi-static tune-away pattern and at least one dynamic tune-away pattern; and
change the state of the UE with respect to the first connection.

15. The UE of claim 14 , wherein the generating for transmission occurs prior to the first change of state.

16. The UE of claim 14 , wherein the first change of state comprises changing a capability of the UE with respect to the first connection.

17. The UE of claim 16 , wherein the changing the capability comprises one of tuning all receive chains of the UE from the first connection to the second connection, tuning some of the receive chains of the UE from the first connection to the second connection, turning off all of the receive chains of the UE, or turning off some of the receive chains of the UE.

18. A processor configured to perform operations comprising:
determining an upcoming first change of a state of a user equipment (UE) with respect to a first connection, wherein the UE configured with the first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured with a second connection to a second network based on a second SIM of the UE;
generating, for transmission to the first network, a radio resource control (RRC) message including an indication of the first change of state of the UE and multiple tune-away patterns, the multiple tune-away patterns comprising at least one semi-static tune-away pattern and at least one dynamic tune-away pattern; and
changing the state of the UE with respect to the first connection.

19. The processor of claim 18 , wherein the generating for transmission occurs prior to the first change of state.

20. The processor of claim 18 , wherein the first change of state comprises changing a capability of the UE with respect to the first connection.
