Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a base station a measurement configuration signal comprising a measurement resource configuration associated with a cross-link interference signal strength measurement. The UE may perform the cross-link interference signal strength measurement for one or more UEs associated with one or more intra-frequency neighboring cells according to the measurement resource configuration, wherein the cross-link interference signal strength measurement is performed during an intra-frequency measurement gap. The UE may transmit a report of the cross-link interference signal strength measurement to the base station.

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

receiving from a network device a measurement configuration signal comprising a measurement resource configuration associated with a cross-link interference signal strength measurement, wherein the measurement resource configuration indicates a number of slots associated with a periodicity for the cross-link interference signal strength measurement;

performing the cross-link interference signal strength measurement for one or more UEs associated with one or more intra-frequency neighboring cells according to the measurement resource configuration;

determining, based at least in part on the number of slots and a subcarrier spacing associated with a link between the UE and the network device, the periodicity for the cross-link interference signal strength measurement; and

transmitting a report of the cross-link interference signal strength measurement to the network device, wherein the report is transmitted periodically based at least in part on the determined periodicity.

2. The method of claim 1 , wherein the measurement resource configuration comprises one or more of a reporting configuration for the cross-link interference signal strength measurement, a filtering configuration for the cross-link interference signal strength measurement, a measurement gap configuration for the cross-link interference signal strength measurement, or a quantity configuration for the cross-link interference signal strength measurement.

3. The method of claim 2 , wherein the cross-link interference signal strength measurement is performed during an intra-frequency measurement gap based at least in part on the measurement gap configuration.

4. The method of claim 1 , further comprising:

determining to perform the cross-link interference signal strength measurement during a discontinuous reception (DRX) off period based at least in part on a measurement accuracy threshold.

5. The method of claim 1 , further comprising:

detecting that a triggering condition for an event is fulfilled based at least in part on a comparison of the cross-link interference signal strength measurement to a threshold, wherein transmitting the report is further based at least in part on the event.

6. The method of claim 5 , wherein the triggering condition comprises one or more of a first triggering condition associated with the cross-link interference signal strength measurement falling below a low threshold or a second triggering condition associated with the cross-link interference signal strength measurement exceeding a high threshold.

7. The method of claim 1 , further comprising:

receiving from the network device an indication of a type of cross-link interference signal strength measurement, wherein performing the cross-link interference signal strength measurement and reporting the cross-link interference signal strength measurement are based at least in part on the indicated type of cross-link interference signal strength measurement.

8. The method of claim 7 , wherein the indication of the type of cross-link signal is received as one or more of: an explicit signal of the type of cross-link signal or an implicit indication of the type of cross-link signal.

9. The method of claim 7 , wherein the indicated type of cross-link interference signal strength measurement comprises one or more of a cross-link interference received signal strength indicator (RSSI) measurement type or a sounding reference signal received signal received power (RSRP) measurement type.
