Abstract

Claims (40)

1 . A method performed by a wireless device for Cross-Link Interference, CLI, reporting, the method comprising:

storing a CLI measurement;

receiving a request to report the CLI measurement from a network node involved in a handover procedure for the wireless device; and

transmitting a CLI measurement report to the network node based on the CLI measurement, wherein the CLI measurement comprises a plurality of CLI resources; and

wherein storing the CLI measurement comprises storing a subset of CLI resources of the plurality of CLI resources based at least in part on a degree of interference associated with the subset of CLI resources.

2 . The method of claim 1 , wherein storing the CLI measurement comprises storing the CLI measurement in response to receiving a measurement configuration.

3 . The method of claim 2 , wherein receiving the measurement configuration comprises receiving the measurement configuration from the network node.

4 . The method of claim 2 , wherein the measurement configuration indicates the wireless device shall store the CLI measurement in case of a handover.

5 . The method of claim 4 , wherein:

the measurement configuration further indicates that the case of the handover is a handover from a first network node to a second network node; and

wherein the handover procedure for the wireless device comprises a handover procedure from the network node to a second network node.

6 . The method of claim 2 , wherein the measurement configuration is received in a RRCReconfiguration message.

7 . The method of claim 1 , further comprising transmitting an indication that CLI measurement information is available after storing the CLI measurement.

8 . The method of claim 7 , wherein transmitting the indication that the CLI measurement information is available comprises transmitting, to the network node, an indication that CLI measurement information is available after storing the CLI measurement; and

wherein the indication comprises:

(a) a flag associated with a Radio Link Failure, RLF, reporting framework; or

(b) a CLI-specific indication.

9 . The method of claim 7 , wherein the indication that the CLI measurement information is available is transmitted in a RRCReestablishmentComplete message.

10 . The method of claim 1 , wherein:

the request to report the CLI measurement is received in a UEInformationRequest message; and

the CLI measurement report is transmitted in a UEInformationResponse message.

11 . The method of claim 1 , wherein the CLI measurement report is provided in response to a radio link failure during the handover procedure.

12 . The method of claim 1 , wherein the CLI measurement report is provided after successful completion of the handover procedure.

13 . The method of claim 1 , wherein the network node is a New Radio Base Station, gNB.

14 . The method of claim 13 , wherein the network node is a source gNB in the handover procedure for the wireless device.

15 . The method of claim 1 , wherein the CLI measurement comprises a plurality of CLI resources, and wherein the CLI measurement report is descriptive of a subset of the plurality of CLI resources.

16 . The method of claim 15 , wherein the subset of CLI resources is associated with:

(a) a certain frequency range;

(b) one or more specific interferers that are close to a resource in which random access attempts and subsequent messages are transmitted; and/or

(c) a time at which the subset of CLI resources were collected.

17 . The method of claim 1 , wherein the request to report the stored CLI measurement from the network node comprises a request to report the stored CLI measurement within (a) a RLF report or (b) a CLI-specific container.

18 . The method of claim 1 , wherein the CLI measurement comprises a measurement of interference, at the wireless device, between neighboring cells due to different transmission directions on the neighboring cells on the same or partially-overlapping time-frequency resources.

19 . A User Equipment, UE, comprising:

one or more transmitters;

one or more receivers; and

processing circuitry configured to cause the UE to:

i. store a CLI measurement;

ii. receive a request to report the CLI measurement from a network node involved in a handover procedure for the wireless device; and

iii. transmit a CLI measurement report to the network node based on the CLI measurement, wherein the CLI measurement comprises a plurality of CLI resources; and

wherein storing the CLI measurement comprises storing a subset of CLI resources of the plurality of CLI resources based at least in part on a degree of interference associated with the subset of CLI resources.
