A method performed by a first communication device is disclosed herein. The first communication device operates in a communications network. The first communication device selects a first method to decode a physical broadcast channel from a plurality of methods to decode the physical broadcast channel. The plurality of methods to decode the physical broadcast channel comprises: a) single-shot decoding only, b) soft-combining decoding only, and c) both single-shot decoding and soft-combining decoding simultaneously. The selecting is based on whether or not a time index of a synchronization signal and physical broadcast channel block, SS/PBCH block, for transmitting primary and secondary synchronization signals and a physical broadcast channel is known by the first communication device. The first communication device then decodes the received physical broadcast channel based on the selected first method.
