When UE receives rrcConnectionReject, the message will have a wait_time; this value will be assigned to the timer T302 and this timer will be started. After this timer expiry, UE will trigger the RACH procedure again for the same eNB.
The T300 timer is started when the UE sends an RRCConnectionRequestmessage. If the timer expires before the UE has received a response in the form of an RRCConnectionSetupor Reject, the UE informs the higher layers and ends the connection procedure.
I saw RRC Connection Reject message in specification. There is an IE "deprioritisationReq" within the RRCConnectionReject message. I want to know when eNodeB includes this IE while rejecting a rrc connection request for an UE.
Suppose a macro eNodeB supports multiple cells. Does each cell has its own instance for each layer or one instance of each protocol layer can handle more than one cell ?
