Network Entry in IEEE 802.16j-2009

An MS under an MR network would undergo the same procedures for network entry, initialization, and periodic ranging as it would in a PMP network. To achieve this compatibility, there are operations to be noted by the MR-BS and the RS in order to maintain a non-MR activity for the MS. As such, operations made on part of an MS during these procedures will not be discussed in this section. The scope of this section hence will comprise two sets of descriptions, a description of the actions taken by an MR-BS to carry out MS procedures, and a description of the procedures required for RS operation. An RS naturally requires additional steps to become fully operational. Figure 5.2 schematizes the network entry and initialization procedures for an RS. The standard distinguishes eleven major steps, with four additional sub-procedures required for RS. In the following list, the optional procedures are marked with an asterisk (*). A distinction is also made between the procedures required for SS only or RS only.

  1. Scanning and synchronization;

    a1. Performing first stage access station selection (RS only);

  2. Obtaining transmission parameters from UCD message;
  3. Ranging;
  4. Negotiating basic capabilities;
  5. Authorizing SS/RS and performing key exchange*;
  6. Performing registration;

    f1. Obtaining neighbor station measurement report (RS only)*;

    f2. Performing the second station access selection (RS only)*;

    f3. Path creating and tunnel establishment (RS only)*;

  7. Establishing ...
