Abstract: This disclosure provides systems, methods and apparatuses for measurement of cells and determination of a non-standalone (NSA) coverage status using an NSA coverage database. The NSA coverage database may indicate candidate frequencies of New Radio (NR) cells that provide NSA coverage corresponding to a given Long Term Evolution (LTE) serving cell. The NSA coverage database may also indicate whether a system information block 1 (SIB1) has been previously received on a candidate frequency. The user equipment (UE) may perform measurement of candidate frequencies using the NSA coverage database, and may identify cases where a cell not providing NSA coverage has a same candidate frequency as a cell providing NSA coverage using the indication of whether SIB1 has been previously received on a candidate frequency.

Abstract: Apparatus, methods, and computer-readable media for enhanced inter-frequency detection between misaligned base stations are disclosed herein. A user equipment (UE) may determine that a neighbor cell associated with a first frequency is misaligned with a serving cell associated with a second frequency different than the first frequency based on first measurements of the neighbor cell within a first measurement gap window having a first length. The UE may detect a location of a synchronization signal block (SSB) associated with the neighbor cell within a second measurement gap window having a second length greater than the first length. The UE may determine an alignment offset between the location of the SSB and the first measurement gap window. The UE may obtain second measurements of the neighbor cell within a third measurement gap window that includes the location of the SSB based on the alignment offset and parameters of the SSB.
