Let's use 10MHz FDD LTE as an example.  As we know the number of radio resource blocks (RBs) assigned for each PDSCH can be between 1~50.  This is for both traffic radio bearer and signaling radio bearer.  My question is, is there any limitation on what is the maximum number of RBs can be assigned for signaling radio bearer?

It sounds like this is an eNodeB scheduling issue.  It may be up to the implementation of each eNB.   But my intuition tells me there must be some upper limit per UE.  Any clue?

Thank you very much!

4.2.2 Signalling radio bearers

"Signalling Radio Bearers" (SRBs) are defined as Radio Bearers (RB) that are used only for the transmission of RRC

and NAS messages. More specifically, the following three SRBs are defined:

- SRB0 is for RRC messages using the CCCH logical channel;

- SRB1 is for RRC messages (which may include a piggybacked NAS message) as well as for NAS messages

prior to the establishment of SRB2, all using DCCH logical channel;

- SRB2 is for NAS messages, using DCCH logical channel. SRB2 has a lower-priority than SRB1 and is always

configured by E-UTRAN after security activation.
