• synchronizing timing at the UE using the reference sequence;
• decoding the encoded payload to obtain at least a format for a system information transmission request and a resource allocation for the system information transmission request, wherein the system information transmission request is a request to transmit a system information block (SIB);
• and transmitting the system information transmission request to a zone node based on information obtained in the synchronization channel, wherein the system information transmission request is transmitted according to the resource allocation.

An apparatus configured for wireless communication, comprising:

• means for generating a reference sequence correlating to a timing of a zone node defining a zone along with one or more other zone nodes;
