180 E6651A User’s Guide
A Appendix A - Network Entry Procedure
Registration Procedure
After the negotiation of physical layer properties, the SS
enters the registration procedure with the BS using the
REG- REQ / REG- RSP message pair.
Using its primary CID, the SS sends a BW- REQ message to
request a new uplink region for the transmission of user
traffic. The BS responds with a ALLOC UL- MAP message
containing updated bandwidth allocation and primary CID
information.
Once the SS has received this information, it proceeds
through the registration process consisting of the REG- REQ
sent to the BS, followed by the receipt of a REG-RSP from
the BS. The completion of the registration process marks the
end of the Network Entry procedure.
The Registration Procedure as seen in the Measurement
Window of the E6651A is shown in Figure 48.
