Transmission and reception of broadcast information in a wireless communication system

A network node for a wireless communication system, the network node adapted to:

• allocate a transmission unit where, in a time-domain, at least a portion of the transmission unit overlaps at least a portion of a set of Synchronization Signal Block, SSB, time-frequency resources to be used for transmission of an SSB, wherein the transmission unit is a transmission unit having a duration that is two or more symbols but less than a duration of a full slot;
• assign Other Broadcast Information, OBI, to time-frequency resources in the transmission unit;
• and
• transmit the transmission unit comprising the OBI or cause transmission of the transmission unit comprising the OBI by a remote radio unit(s);
• wherein:
• the SSB comprises a Primary Synchronization Signal, PSS, a Secondary Synchronization Signal, SSS, and a Physical Broadcast Channel, PBCH;
• and
• the OBI comprises paging messages, Remaining Minimum System Information, RMSI, and/or Random Access Response, RAR, messages.
