Abstract

Certain aspects of the present disclosure provide techniques for protecting overhead and common channel transmissions in a NR shared spectrum system. A BS of a first operator may receive information regarding at least one overhead transmission associated with a wireless device of a second operator and may protect one or more overhead signal transmissions of the wireless device based, at least in part, on the received information. A UE may detect information associated with at least one overhead transmission from a wireless device associated with a first operator and may transmit the information regarding the detected overhead transmission to a BS associated with a second operator. A UE served by a BS associated with a first operator may detect a wireless device (e.g., another UE or a BS) associated with a second operator. The UE may report an identification of the wireless device to the BS.

Claims

1. A method for wireless communication by a base station (BS) of a first operator, comprising:

receiving information regarding at least one overhead transmission associated with a wireless device of a second operator; and

protecting one or more overhead signal transmissions of the wireless device based, at least in part, on the received information.

2. The method of claim 1, wherein transmissions of the wireless device are asynchronous to transmissions of the BS.

3. The method of claim 1, wherein receiving the information comprises:

receiving the information from one of a user equipment (UE) served by the BS, a UE not served by the BS, or the wireless device.

4. The method of claim 1, further comprising:

determining at least one of system information or configuration information associated with the wireless device based, at least in part, on the received information.

5. The method of claim 4, wherein the receiving comprises:

receiving information regarding at least one of the system information or the configuration information associated with the wireless device.

6. The method of claim 1, wherein the receiving comprises:

receiving information associated with an identity of the wireless device.

7. The method of claim 6, further comprising:

establishing communication with the wireless device using the received identity; and

determining at least one of system information or configuration information associated with the wireless device based, at least in part, on the communication.

8. The method of claim 1, wherein protecting the one or more overhead signal transmissions of the wireless device comprises at least one of:

refraining from transmitting, by the BS, during a future overhead signal transmission of the wireless device or transmitting during a future overhead signal transmission of the wireless device using a reduced transmit power.

9. The method of claim 1, further comprising:

scheduling multiple overhead signal transmissions by the BS to occur within a period of time that is less than a threshold value.

10. The method of claim 1, wherein the information is received from a network server.

11. The method of claim 10, further comprising:

receiving, from a first user equipment (UE) served by the BS, an indication of a second UE served by the wireless device; and

reporting detection of the second UE to the network server,

wherein the information from the network server is responsive to the reporting.

12. A method for wireless communication by a user equipment (UE), comprising:

detecting information associated with at least one overhead transmission from a wireless device associated with a first operator; and

transmitting the information regarding the detected overhead transmission to a base station (BS) associated with a second operator.

13. The method of claim 12, wherein the UE is not served by the BS.

14. The method of claim 12, wherein the detecting comprises:

decoding information from at least one of downlink discovery signals, downlink paging occasions, uplink random access opportunities, or uplink discovery signals associated with the wireless device.

15. The method of claim 12, further comprising:

determining at least one of system information or configuration information associated with the wireless device based, at least in part, on the detected information.

16. The method of claim 15, wherein the transmitting comprises:

transmitting, to the BS, information regarding at least one of the system information or configuration information associated with the wireless device.

17. The method of claim 12, wherein the transmitting comprises:

transmitting, to the BS, information associated with an identity of the wireless device.

18. A method for wireless communication by a first user equipment (UE) served by a base station (BS) of a first operator, comprising:

detecting a wireless device of a second operator; and

reporting an identification associated with the wireless device to the BS.

19. The method of claim 18, wherein the detecting comprises:

detecting a second UE served by the wireless device.

20. An apparatus for wireless communication by a user equipment (UE), comprising at least one processor configured to:

detect information associated with at least one overhead transmission from a wireless device associated with a first operator; and

transmit the information regarding the detected overhead transmission to a base station (BS) associated with a second operator; and

a memory coupled to the at least one processor.

21. The apparatus of claim 20, wherein the UE is not served by the BS.

22. The apparatus of claim 20, wherein the detecting comprises:

decoding information from at least one of downlink discovery signals, downlink paging occasions, uplink random access opportunities, or uplink discovery signals associated with the wireless device.

23. The apparatus of claim 20, wherein the at least one processor is configured to:

determine at least one of system information or configuration information associated with the wireless device based, at least in part, on the detected information.

24. The apparatus of claim 23, wherein the transmitting comprises:

transmitting, to the BS, information regarding at least one of the system information or configuration information associated with the wireless device.

25. The apparatus of claim 20, wherein the transmitting comprises:

transmitting, to the BS, information associated with an identity of the wireless device.
