Non-independent coverage state determination

This disclosure provides systems, methods, and apparatus for measuring cells and determining NSA coverage status using a non-independent (NSA) coverage database. The NSA coverage database can 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 the candidate frequency. A user equipment (UE) can use the NSA coverage database to perform measurements of candidate frequencies, and can use an indication of whether SIB1 has been previously received on the candidate frequencies to identify where a cell that does not provide NSA coverage has the same candidate frequency as a cell that provides NSA coverage. 本公开提供了用于使用非独立（NSA）覆盖数据库来测量小区以及确定NSA覆盖状态的系统、方法和装置。该NSA覆盖数据库能够指示提供与给定长期演进（LTE）服务小区相对应的NSA覆盖的新无线电（NR）小区的候选频率。该NSA覆盖数据库还可以指示先前是否已在候选频率上接收到系统信息块1（SIB1）。用户装备（UE）能够使用该NSA覆盖数据库来执行对候选频率的测量，并且能够使用先前是否已在候选频率上接收到SIB1
