MeshSynchronzation

When a node is turned on, the following initial procedure is started

1. It looks for a CHSCH 1,2,3 and tries to decode CHBCH 1,2,3
2. If successful it declares itself synched to CHSCH and becomes a MR
3. Otherwise it looks for a MRSCH and tries to decode MRBCH
4. If successful, it declares itself synched to MRSCH and becomes a secondary CH
5. Otherwise it becomes a primary CH

Depending on its role, a running node performs the following tracking procedure

1. Primary CH:
2. Secondary CH: track the MRSCH, but keep running even in case it looses the MRSCH
3. MR: track all available CHSCH and adjust the transmission
   • If all the CHSCH are received within the length of a cyclic prefix --> okay
   • If the CHSCH are further than cyclic prefix apart, send a timing advance message to the first (to be done in higher layers)
