Abstract

Methods, systems, and apparatuses are described for a base station initiated control mechanism for supporting supplemental a link. In some aspects, control information associated with a directional, first radio access technology (RAT) for a user equipment (UE) may be identified at a first base station, the first base station configured to communicate with the UE using the directional, first RAT, and the control information associated with the directional, first RAT may be transmitted to a second base station to forward to the UE using a second RAT.

Claims

1. An apparatus for wireless communication, comprising:

a processor;

memory in electronic communication with the processor; and

instructions stored in the memory, the instructions being executable by the processor to;

receive, at a user equipment (UE), control information associated with a directional, first radio access technology (RAT) for a first base station, the first base station configured to communicate with the UE using the directional, first RAT, the control information being received at the UE from a second base station, the second base station configured to communicate with the UE using a second RAT, the directional, first RAT being different from the second RAT, and the control information for managing a directional connection between the UE and the first base station via the directional, first RAT; and

transmit response information to the second base station using the second RAT, the response information being forwarded to the first base station based at least in part on the received control information.

2. The apparatus of claim 1, wherein the memory further comprises instructions being executable by the processor to perform a task responsive to the received control information, the response information comprising results of the performed task.

3. The apparatus of claim 1, wherein the memory further comprises instructions being executable by the processor to forward information indicating to the UE to transmit the response information to the second base station for forwarding to the first base station over a backhaul link between the second base station and the first base station.

4. The apparatus of claim 1, wherein the response information comprises one or more of a channel quality indication (CQI) report, a keep-alive message reply, beam change information, beam searching information, or a combination thereof.

5. The apparatus of claim 1, wherein the control information is first received at the second base station from the first base station and then forwarded to the UE from the second base station using the second RAT.

6. An apparatus for wireless communication, comprising:

a processor;

memory in electronic communication with the processor; and

instructions stored in the memory, the instructions being executable by the processor to;

receive, from a first base station, control information associated with a directional, first radio access technology (RAT) for a user equipment (UE), the first base station configured to communicate with the UE using the directional, first RAT; and

determine whether to forward the control information to the UE using a second RAT, the directional, first RAT being different from the second RAT, and the control information for managing a directional connection between the UE and the first base station via the directional, first RAT.

7. The apparatus of claim 6, wherein the memory further comprises instructions being executable by the processor to selectively forward the control information to the UE based at least in part on the determination.

8. The apparatus of claim 6, wherein the memory further comprises instructions being executable by the processor to selectively transmit a notification to the first base station when the control information is not forwarded to the UE.

9. The apparatus of claim 6, wherein the memory further comprises instructions being executable by the processor to transmit the control information to the UE over a control channel or a data channel associated with the second RAT.

10. The apparatus of claim 6, wherein the memory further comprises instructions being executable by the processor to:

receive response information from the UE responsive to the control information; and

forward the response information to the first base station over a backhaul link.

11. A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable to:

receive, at a user equipment (UE), control information associated with a directional, first radio access technology (RAT) for a first base station, the first base station configured to communicate with the UE using the directional, first RAT, the control information being received at the UE from a second base station, the second base station configured to communicate with the UE using a second RAT, the directional, first RAT being different from the second RAT, and the control information for managing a directional connection between the UE and the first base station via the directional, first RAT; and

transmit response information to the second base station using the second RAT, the response information being forwarded to the first base station based at least in part on the received control information.

12. The non-transitory computer-readable medium of claim 11, wherein the code further comprises instructions executable to perform a task responsive to the received control information, the response information comprising results of the performed task.

13. The non-transitory computer-readable medium of claim 11, wherein the code further comprises instructions executable to forward information indicating to the UE to transmit the response information to the second base station for forwarding to the first base station over a backhaul link between the second base station and the first base station.

14. The non-transitory computer-readable medium of claim 11, wherein the response information comprises one or more of a channel quality indication (CQI) report, a keep-alive message reply, beam change information, beam searching information, or a combination thereof.

15. The non-transitory computer-readable medium of claim 11, wherein the control information is first received at the second base station from the first base station and then forwarded to the UE from the second base station using the second RAT.

16. A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable to:

receive, from a first base station, control information associated with a directional, first radio access technology (RAT) for a user equipment (UE), the first base station configured to communicate with the UE using the directional, first RAT; and

determine whether to forward the control information to the UE using a second RAT, the directional, first RAT being different from the second RAT, and the control information for managing a directional connection between the UE and the first base station via the directional, first RAT.

17. The non-transitory computer-readable medium of claim 16 wherein the code further comprises instructions executable to selectively forward the control information to the UE based at least in part on the determination.

18. The non-transitory computer-readable medium of claim 16, wherein the code further comprises instructions executable to selectively transmit a notification to the first base station when the control information is not forwarded to the UE.

19. The non-transitory computer-readable medium of claim 16, wherein the code further comprises instructions executable to transmit the control information to the UE over a control channel or a data channel associated with the second RAT.

20. The non-transitory computer-readable medium of claim 16, wherein the code further comprises instructions executable to:

receive response information from the UE responsive to the control information; and

forward the response information to the first base station over a backhaul link.
