Citizens broadband radio service network interference management using dual subscriber identification module devices

A method for measuring network interference using dual subscriber identification module (SIM) devices, the method comprising:

• generating, by each shared spectrum interference based device, a physical cell identity (PCI) table by exchanging PCIs with neighbor shared spectrum interference based devices for a defined period of time to resolve non-overlapping PCI usage;
• reporting, to a spectrum access system (SAS) by each shared spectrum interference based device having at least one connected dual SIM device, a number of PCIs detected by the at least one dual SIM device using a SIM device;
• sharing, by each shared spectrum interference based device having the at least one connected dual SIM device, a PCI table with a selected dual SIM device;
• measuring, by each selected dual SIM device using another SIM device, power values of PCIs detected by each selected dual SIM device which are missing from the shared PCI table;
• and
• making spectrum interference decisions, by the SAS, based on the measured power values.

A system for measuring network interference using dual subscriber identification module (SIM) devices, the system comprising:

• a plurality of Citizens Broadband Radio Service (CBRS) devices (CBSDs) forming a first cluster, wherein each CBSD and CBSD sector have a physical cell identity (PCIs) which are exchanged between neighboring CBSDs within the first cluster to yield unique PCIs for each CBSD and CBSD sector;
• another plurality of Citizens Broadband Radio Service (CBRS) devices (CBSDs) forming a second cluster, wherein each CBSD and CBSD sector have a physical cell identity (PCIs) which are exchanged between neighboring CBSDs within the second cluster to yield unique PCIs for each CBSD and CBSD sector, and wherein the first cluster and the second cluster have non-overlapping CB SDs;
• a spectrum access system (SAS) configured to grant unlicensed spectrum to the plurality of CBSDs and the another plurality of CBSDs;
• at least one dual SIM device configured to connect via a first SIM to a CBSD in one of the first cluster or the second cluster and report a number of detected PCIs using the first SIM;
• a selected dual SIM device configured to take power measurements, via a second SIM, of PCIs detected by the selected dual SIM device which are in one of the first cluster or the second cluster unassociated with the CBSD and are missing from a PCI table shared by the CBSD, and wherein the selected dual SIM device is selected from the at least one dual SIM device by the SAS;
• and
• the SAS configured to make inter-cluster interference decisions based on received power measurements from the selected dual SIM device using the second SIM.
