In some aspects, a user equipment (UE) may establish inter-band carrier aggregation with a synchronization signal block (SSB) anchor carrier and an SSB-less carrier. The UE may measure a synchronization signal (SS) reference signal received quality (RSRQ) of the SSB-less carrier based on a ratio of a quantity of resource blocks multiplied by an SS reference signal received power (RSRP) and divided by a New Radio (NR) received signal strength indicator (RSSI), where the SS-RSRP is measured based on an SSB on the anchor carrier. Numerous other aspects are described. ## Claims ### Claim 1 A user equipment (UE) for wireless communication, comprising: a memory; and one or more processors, coupled to the memory, configured to: establish inter-band carrier aggregation with a synchronization signal block (SSB) anchor carrier and an SSB-less carrier;
