Abstract

A method, network node and wireless device for flexible configuration of channel occupancy measurements in New Radio (NR) are disclosed. According to one aspect, a wireless device configured to communicate with a network node is provided. The wireless device includes processing circuitry configured to: determine a time-domain configuration for a channel occupancy measurement based on at least one configuration parameter where the time-domain configuration is independent of subcarrier spacing of at least one carrier on which the channel occupancy measurement is performed; and optionally perform the channel occupancy measurement based at least on the determined time-domain configuration.

First claim

What is claimed is:

1. A method implemented by a wireless device that is configured to communicate with a network node, the method comprising:
receiving from the network node at least one configuration parameter for a channel occupancy measurement;
determining a measurement duration for the channel occupancy measurement based on at least one configuration parameter, the measurement duration being independent of a subcarrier spacing for time-frequency resources in which the channel occupancy measurement is performed; and
performing the channel occupancy measurement based at least on the determined measurement duration.

2. The method of claim 1 , further comprising determining a frequency-domain configuration for the channel occupancy measurement based on the at least one configuration parameter, the frequency-domain configuration being independent of subcarrier spacing for time-frequency resources in which the channel occupancy measurement is performed; and
performing the channel occupancy measurement additionally based at least on the determined frequency-domain configuration.

3. The method of claim 2 , wherein the frequency-domain configuration is a measurement bandwidth of the channel occupancy measurement.

4. The method of claim 2 , wherein the at least one configuration parameter comprises a center frequency of a measurement bandwidth.

5. The method of claim 1 , wherein the at least one configuration parameter comprises a reference sub-carrier spacing and a quantity of symbols.

6. The method of claim 1 , further comprising reporting the channel occupancy measurement.

7. The method of claim 1 , wherein the channel occupancy measurement is a received signal strength indicator (RSSI) measurement, and the RSSI measurement is scaled with a first bandwidth.

8. The method of claim 1 , wherein the at least one configuration parameter is configured to be applied to at least one of multiple subband and bandwidth parts, BWPs of a serving cell provided by the network node.

9. The method of claim 1 , wherein the at least one configuration parameter is received separately from a synchronization signal block (SSB) frequency information element ssbFrequency and a channel state information reference signal (CSI-RS) frequency information element refFreqCSI-RS.

10. A method implemented by a network node that is configured to communicate with a wireless device, the method comprising:
causing transmission of at least one configuration parameter for a channel occupancy measurement that is configured to indicate a measurement duration for the channel occupancy measurement, the measurement duration being independent of subcarrier spacing for time-frequency resources in which the channel occupancy measurement is performed.

11. The method of claim 10 , further comprising receiving the channel occupancy measurement that is associated with the at least one configuration parameter.

12. The method of claim 10 , wherein the at least one configuration parameter is further configured to indicate a frequency-domain configuration for the channel occupancy measurement, the frequency-domain configuration being independent of subcarrier spacing for time-frequency resources in which the channel occupancy measurement is performed.

13. The method of claim 12 , wherein the frequency-domain configuration is a measurement bandwidth of the channel occupancy measurement.

14. The method of claim 13 , wherein the at least one configuration parameter comprises a center frequency of the measurement bandwidth.

15. The method of claim 10 , wherein the at least one configuration parameter comprises a reference sub-carrier spacing and a quantity of symbols for the measurement duration.

16. The method of claim 10 , wherein the channel measurement is a received signal strength indicator, RSSI, measurement.

17. The method of claim 16 , wherein the RSSI measurement is scaled with a first bandwidth.

18. The method of claim 10 , wherein the at least one configuration parameter applies to at least one of multiple subband and bandwidth parts, BWPs of a serving cell provided by the network node.

19. The method of claim 10 , wherein the at least one configuration parameter is transmitted separately from a synchronization signal block (SSB) frequency information element ssbFrequency and a channel state information reference signal (CSI-RS) frequency information element refFreqCSI-RS.

20. The method of claim 10 , further comprising:
receiving a neighbor channel occupancy measurement from another network node; and
adjusting scheduling associated with the wireless device based on the neighbor channel occupancy measurement.
