  • Technique for Transmitting System Information
    Publication number: 20210099944
    Abstract: A technique for transmitting system information for a time-division duplex, TDD, communication in a radio access network, RAN, is described. As to a method aspect of the technique, a master information block, MIB, is transmitted on an anchor carrier (602 1) of the TDD communication in the RAN. The MIB is indicative of a spectral resource (602-1; 602-2) allocated to a system information block, SIB, of the TDD communication in the RAN. The SIB is transmitted on the spectral resource (602-1; 602-2) indicated in the MIB.
