  • Synchronization signal / physical broadcast channel block method detection and management
    Patent number: 12273289
    Abstract: Synchronization signal and Physical Broadcast Channel, SS/PBCH, block management. A network node determines whether a network condition is met, signals to a communication terminal to apply a first detection method for SS/PBCH block detection when the network condition is determined to be met, signals to the communication terminal to apply a second detection method for SS/PBCH block detection when the network condition is determined as not met, and transmits SS/PBCH blocks according to the first or the second SS/PBCH block detection method, based on whether the network condition is met. The communication terminal receives the signalling from the network node associated with the communication network, determines whether the indicated SS/PBCH block detection method is a first or a second SS/PBCH block detection method based on the received signalling, and applies, based on the determination, the first or the second SS/PBCH block detection method for SS/PBCH block detection.
