  • Methods, network node and wireless device for handling access information
    Patent number: 10701620
    Abstract: A radio network (600) comprising at least one network node (604) broadcasts access information (AIT) comprising a range of access parameters, using a demodulation reference signal (RS4) out of a set of predefined demodulation reference signals. The radio network (600) also transmits a synchronization signal (SSI 7) associated with a predefined mapping to at least two candidate demodulation reference signals including the demodulation reference signal used for broadcasting the access information. Thereby, a wireless device (602) receiving the synchronization signal is able to demodulate the broadcasted access information and derive valid access related parameters therefrom, based on the synchronization signal (SSI 7).
