A Appendix A - Network Entry Procedure Network Entry Procedure Overview A Mobile WiMAX subscriber station (SS) executes the Network Entry procedure in order to begin two way communications with any base station, including the E6651A Mobile WiMAX Test Set. The SS executes this procedure after acquiring relevant information from broadcast messages.
Appendix A - Network Entry Procedure A The flow diagram in Figure 44 depicts the general Network Entry procedure of the SS. “Network Entry Procedure Detail" on page 174 provides detail on each step in the Network Entry procedure.
A Appendix A - Network Entry Procedure Network Entry Procedure Detail The Test Set engages in the Network Entry procedure when establishing two way communications with the SS. The messages transmitted during the each phase of the Network Entry procedure are displayed in the Measurement Window when the Test Set is operating in BSE mode. The following sections describe the detailed steps in the procedure, and show the operation of the Test Set for each step.
Appendix A - Network Entry Procedure A frequency. The broadcast operation of the product for downlink synchronization and uplink parameter information is shown in Figure 46.
A Appendix A - Network Entry Procedure Initial Ranging Procedure Execution and Basic Capabilities Negotiation Using the initial ranging region information and initial ranging code information obtained from the UL- MAP and UCD messages, the SS attempts the Contention Based Initial Ranging procedure. The E6651A measures the quality of the initial ranging code.
A Appendix A - Network Entry Procedure The Initial Ranging Procedure and Negotiation of Basic Capabilities as seen in the Measurement Window of the E6651A are shown in Figure 47.
A Appendix A - Network Entry Procedure • Ranging Power (RP): The power information for the Initial Ranging Code This is the response to the Ranging Code or RNG- REQ message sent from the BS to the SS.
Appendix A - Network Entry Procedure SBC-RSP MAC Management Message A The BS sends this message to the SS in response to the request for basic physical layer properties.
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.
Appendix A - Network Entry Procedure A • Hashed Message Auth Code • IP Version • Vendor ID • CS Capability • ARQ Parameter REG-RSP MAC Management Message The BS sends this message to the SS in response to the registration request.
A Appendix A - Network Entry Procedure Periodic Ranging for Connection Maintenance After the Network Entry procedure has been completed, the SS engages in the Periodic Ranging procedure to assist in maintaining a reliable connection with the network. The Periodic Ranging Procedure as seen in the Measurement Window of the E6651A is shown in Figure 49.
A Appendix A - Network Entry Procedure • Ranging Matching Rate (RM): The ratio of valid Periodic Ranging attempts to total ranging attempts • Ranging Power (RP): The power information for the Periodic Ranging Code REP-REQ message Setting The E6651A Test Set can control the transmission of REP- REQ message. The message is sent from BS to SS and is used to get the SS's status information by the BS. Two control parameters are provided. • REP- REQ msg. Enable/Disable Setting • REP- REQ msg.
A Appendix A - Network Entry Procedure Repetition Setting The E6651A can repeat UL MAP and DL MAP information in downlink frames. The repetition control function is provided as shown in Figure 50 on page 183. And the DL/UL user data repetition function is provided also as shown in Figure 51. Figure 51 BSE Setting function - B Bandwidth Request Mode Setting The E6651A provides two bandwidth allocation algorithms to allocate uplink data region for SS's data transmission. They are BW- REQ and UGS.
Appendix A - Network Entry Procedure A Profile Selection The Profiles are displayed in 2 lists, the File List and the Memory List. The Memory List shows the profiles loaded in FPGA Memory. To be used, a profile must be loaded into FPGA memory. The required profile can be selected for use as follows: 1 Press System > More > Profile Manager to display the Profile Manager screen as shown in Figure 52.
