Abstract

Provided herein are systems and methods of configuring received signal strength indicator (RSSI) measurements to determine crosslink interferences (CLI). For instance, a user equipment (UE) can receive, using radio front-end circuitry, a RSSI resource configuration for CLI measurement from a base station in a 5G network. The UE can then measure a RSSI of one or more received signals based at least in part on the RSSI resource configuration. The UE can then perform one or more CLI measurements based at least in part on the measured RSSI. The RSSI resource configuration includes an identifier information element (IE), one or more slot-level indication IEs, one or more symbol-level indication IEs, one or more physical resource block (PRB)-level indication IEs, one or more resource element (RE) pattern indication IEs, and one or more receive beam indication IEs.

Claims (33)

1. A user equipment (UE), comprising:

radio front end circuitry; and

processor circuitry configured to:

receive, using the radio front end circuitry, a received signal strength indicator (RSSI) resource configuration for crosslink interference (CLI) measurement from a base station;

measure a RSSI of one or more received signals based at least in part on the received RSSI resource configuration; and

perform one or more CLI measurements based at least in part on the measured RSSI;

wherein the RSSI resource configuration includes an identifier information element (IE), one or more slot-level indication IEs, one or more symbol-level indication IEs, one or more physical resource block (PRB)-level indication IEs, one or more resource element (RE) pattern indication IEs, and one or more receive beam indication IEs, and wherein the one or more symbol-level indication IEs comprise a start and length indication value (SLIV) to jointly indicate a start symbol and a length of data transmission having the start symbol to be any symbol in a slot and the length be up to 14 symbols for RSSI measurement over a Physical Uplink Shared Channel (PUSCH).

2. The UE of claim 1 , wherein the one or more slot-level indication IEs indicate whether a slot-level measurement resource is periodic or semi-persistent.

3. The UE of claim 1 , wherein the one or more symbol-level indication IEs comprise a startPosition IE and a nrofSymbols IE.

4. The UE of claim 1 , wherein the one or more symbol-level indication IEs comprise a bitmap indicating orthogonal frequency-division multiplexing (OFDM) symbols for measurement.

5. The UE of claim 1 , wherein the one or more PRB-level indication IEs comprise a resource indicator value (RIV) indicating a starting PRB and a length of continuously allocated PRBs.

6. The UE of claim 1 , wherein the one or more PRB-level indication IEs comprise a bitmap to indicate non-contiguous PRBs for RSSI measurement.

7. The UE of claim 1 , wherein the one or more RE pattern indication IEs comprise one or more resourceElementMapping IEs to indicate an RE pattern for RSSI measurement.

8. The UE of claim 1 , wherein the one or more receive beam indication IEs comprise a spatialRelationInfo IE to indicate a receive beam for RSSI measurement.

9. A method, comprising:

receiving, by a user equipment (UE) in a wireless network, a received signal strength indicator (RSSI) resource configuration for crosslink interference (CLI) measurement from a base station;

measuring, by the UE, a RSSI of one or more received signals based at least in part on the received RSSI resource configuration; and

performing, by the UE, one or more CLI measurements based at least in part on the measured RSSI;

wherein the RSSI resource configuration includes an identifier information element (IE), one or more slot-level indication IEs, one or more symbol-level indication IEs, one or more physical resource block (PRB)-level indication IEs, one or more resource element (RE) pattern indication IEs, and one or more receive beam indication IEs, and wherein the one or more symbol-level indication IEs comprise a start and length indication value (SLIV) to jointly indicate a start symbol and a length of data transmission having the start symbol to be any symbol in a slot and the length be up to 14 symbols for RSSI measurement over a Physical Uplink Shared Channel (PUSCH).

10. The method of claim 9 , wherein the one or more slot-level indication IEs indicate whether a slot-level measurement resource is periodic or semi-persistent.

11. The method of claim 9 , wherein the one or more PRB-level indication IEs comprise a resource indicator value (RIV) indicating a starting PRB and a length of continuously allocated PRBs, or a bitmap indicating non-contiguous PRBs for RSSI measurement.

12. The method of claim 9 , wherein the one or more RE pattern indication IEs comprise one or more resourceElementMapping IEs to indicate an RE pattern for RSSI measurement.

13. The method of claim 9 , wherein the one or more receive beam indication IEs comprise a spatialRelationInfo IE to indicate a receive beam for RSSI measurement.

14. A base station, comprising:

a memory that stores instructions; and

a processor, upon executing the instructions, configured to:

determine a received signal strength indicator (RSSI) resource configuration for crosslink interference (CLI) measurement;

measure RSSI of one or more received signals based at least in part on the RSSI resource configuration; and

perform one or more CLI measurements based at least in part on the measured RSSI;

wherein the RSSI resource configuration includes an identifier information element (IE), one or more slot-level indication IEs, one or more symbol-level indication IEs, one or more physical resource block (PRB)-level indication IEs, one or more resource element (RE) pattern indication IEs, and one or more receive beam indication IEs, and wherein the one or more symbol-level indication IEs comprise a start and length indication value (SLIV) to jointly indicate a start symbol and a length of data transmission having the start symbol to be any symbol in a slot and the length be up to 14 symbols for RSSI measurement over a Physical Uplink Shared Channel (PUSCH).

15. The base station of claim 14 , wherein the one or more slot-level indication IEs indicate whether a slot-level measurement resource is periodic or semi-persistent.

16. The base station of claim 14 , wherein the one or more PRB-level indication IEs comprise a resource indicator value (RIV) indicating a starting PRB and a length of continuously allocated PRBs, or a bitmap indicating non-contiguous PRBs for RSSI measurement.

17. The base station of claim 14 , wherein the one or more RE pattern indication IEs comprise one or more resourceElementMapping IEs to indicate an RE pattern for RSSI measurement, and wherein the one or more receive beam indication IEs comprise a spatialRelationInfo IE to indicate a receive beam for RSSI measurement.
