1. A method performed at a network node for changing a physical cell identifier (PCI), comprising:
transmitting a first signal based on a first physical cell identifier (PCI) during a first synchronization signal block (SSB) occasion;
transmitting a second signal based on the first PCI during a second SSB occasion, wherein the first SSB occasion and the second SSB occasion are part of a set of SSB occasions in a periodically repeating time frame; and
transitioning from the first PCI to a second PCI,
wherein during a transition period, the transitioning comprises:
transmitting the first signal based on the second PCI during the first SSB occasion, and continuing to transmit the second signal based on the first PCI during the second SSB occasion, and
wherein after an end of the transition period, the transitioning comprises:
continuing to transmit the first signal based on the second PCI during the first SSB occasion, and ceasing transmission of the second signal based on the first PCI during the second SSB occasion.
