    Abstract: A circuit arrangement includes a control circuit configured to identify a candidate message in received control data that indicates a potential location of an encoded message in the received control data, the candidate message having a predefined message bit length, a measurement circuit configured to perform a radio measurement, the control circuit further configured to compare the radio measurement to a predefined threshold, and a decoding circuit further configured to, if the radio measurement satisfies the predefined threshold, search for the encoded message in the received control data by decoding the candidate message from the received control data with a reduced message bit length less than the predefined bit length.

    Abstract: A mobile communication device may include a radio transceiver configured to transmit and receive communication signals, and a baseband modem circuit configured to determine a decoded information field of a first encoded system information packet, set one or more bits of the decoded information field as an initial encoder state of a convolutional decoder for decoding the first encoded system information packet, decode the first encoded system information packet with the initial encoder state to obtain a first decoded system information packet, and use the decoded system information packet to transmit or receive data with one or more network cells.
