[求助]Wimax中的三种CLC class是根据什么定义的？

iloveyou123!

Wimax 802.16m（Part 16: Air Interface for Fixed and Mobile Broadband Wireless Access Systems）16.2.20 Co-Located Coexistence (CLC)章节定义了三种CLC class。这三种class是根据什么定义的？
AMS shall determine CLC active interval and CLC active cycle based on the activities of its co-located non 802.16 radios and its 802.16 performance requirements.
根据具体的业务模型么？

有没有大侠有IEEE这方面的讨论历史资料提供啊
