Abstract: A device may receive a first synchronization signal including at least one first synchronization signal block (SSB) from a serving base station and a second synchronization signal including at least one second SSB from a neighboring base station, where the second synchronization signal overlaps a slot through which data is transmitted from the serving base station. Additionally, the device may measure a first received power and a received reference signal received power (RSRP) of each of the first synchronization signal and the second synchronization signal received on the slot. The device may calculate an effective RSRP corresponding to at least one additional SSB received from the serving base station, the effective RSRP calculated based on a correlation power, where the correlation power is based on a cross correlation between the received RSRP, the first received power, the data, and the at least one additional SSB.
