A method, system and apparatus for reducing a number of bits of a physical broadcast channel (PBCH) used to broadcast a configuration of a remaining minimum system information (RMSI) data set as compared with other arrangements are disclosed. According to one aspect, a method in a network node includes determining a remaining minimum system information (RMSI) configuration based on a table of assumptions used to determine a number of bits to represent the RMSI configuration and broadcasting the RMSI configuration using the determined number of bits via a physical broadcast channel (PBCH).
