Transmission and reception of system information in parts

A wireless communication device for receiving system information for a wireless communication system in parts, the wireless communication device comprising:

• a processor and a memory, the memory containing instructions executable by the processor whereby the wireless communication device is configured to:
• receive, over a first channel, a first part of system information;
• receive, over a signaling channel, explicit signaling that is associated with the first part and that indicates a second demodulation reference signal sequence with which the wireless communication device is to demodulate a second part of system information, wherein the second demodulation reference signal sequence with which the wireless communication device is to demodulate the second part of system information is different than a first demodulation reference signal sequence used for demodulating the first part of system information;
• and
• receive the second part of system information over a second channel, by demodulating the second part using the indicated second demodulation reference signal sequence.

A radio node for use in a wireless communication system in which system information is transmitted in parts the radio node comprising:

• a processor and a memory, the memory containing instructions executable by the processor whereby the wireless communication device is configured to:
• generate explicit signaling that is associated with a first part of system information and that indicates a second demodulation reference signal sequence with which a second part of system information is to be demodulated, wherein the second demodulation reference signal sequence is different than a first demodulation reference signal sequence with which the first part of system information is to be demodulated;
• and
• transmit the explicit signaling over a signaling channel.
