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 user equipment (UE), comprising:

detecting information associated with at least one overhead transmission from a wireless device associated with a first operator that is different from an operator associated with the UE, wherein the at least one overhead transmission includes;

at least one of synchronization information from the wireless device or system information from the wireless device; and

an indication of a transmission time associated with the at least one overhead transmission to reduce hidden node interference; and

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

2. The method of claim 1, wherein the UE is not served by the BS.

3. The method of claim 1, wherein the detecting information associated with the overhead transmission 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.

4. The method of claim 1, wherein the information includes at least one of the synchronization information or the system information.

5. The method of claim 1, wherein the information comprises an identity of the wireless device.

13. The method of claim 1, wherein the second operator is associated with the UE and the UE is served by the BS.

6. 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 that is different from an operator associated with the UE, wherein the at least one overhead transmission includes;

at least one of synchronization information from the wireless device or system information from the wireless device; and

an indication of a transmission time associated with the at least one overhead transmission to reduce hidden node interference; and

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

a memory coupled to the at least one processor.

7. The apparatus of claim 6, wherein the UE is not served by the BS.

8. The apparatus of claim 6, wherein the detecting information associated with the overhead transmission 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.

9. The apparatus of claim 6, wherein the information comprises at least one of the synchronization information or the system information.

10. The apparatus of claim 6, wherein the information comprises an identity of the wireless device.

14. The apparatus of claim 7, wherein the second operator is associated with the UE and the UE is served by the BS.

11. An apparatus for wireless communication by a user equipment (UE), comprising:

means for detecting information associated with at least one overhead transmission from a wireless device associated with a first operator that is different from an operator associated with the UE, wherein the at least one overhead transmission includes;

at least one of synchronization information from the wireless device or system information from the wireless device; and

an indication of a transmission time associated with the at least one overhead transmission to reduce hidden node interference; and

means for transmitting the detected information to a base station (BS) associated with a second operator.

12. A non-transitory computer-readable medium for wireless communication by a user equipment (UE), comprising:

instructions that, when executed by at least one processor, cause the at least one processor to;

detect information associated with at least one overhead transmission from a wireless device associated with a first operator that is different from an operator associated with the UE, wherein the at least one overhead transmission includes;

at least one of synchronization information from the wireless device or system information from the wireless device; and

an indication of a transmission time associated with the at least one overhead transmission to reduce hidden node interference; and

transmit the detected information to a base station (BS) associated with a second operator.
