1. Introduction
In current P802.16m/D2, the procedure of network entry and initialization needs clarification.
In this proposal, the procedure of network entry and initialization is provided in a figure.
2. Text Proposal
======================== Start of Proposed Text =====================
Accept the following modification to 15.2.15.1(page 220, line 35):
The AMS shall have nonvolatile storage in which the last operational parameters are stored and may first try
to reacquire the stored DL channel. If the DL Channel is acquired, the AMS can determine the cell type and
select preferred cell based on the stored SA-Preamble partitioning information. If the aforementioned
process fails, the AMS shall begin to scan the possible channels of the DL frequency band of operation until
it finds a valid DL signal.
Replace Figure 442 with the following figure:
