Legacy Support Requirements in SRD
①
16e/16m system shall/should be able to operate
on the same RF carrier with same/different BW16e/16m
Mixed
(a)
②
16m BS shall support a mix of 16e MS
and 16m MS on the same RF carrier (c and e)
③
16m BS shall support 16e MS with the
same performance as 16e BS (b=c)
④
16m BS shall support handover of 16e
MS to/from 16e BS (b <--> c)
⑤
16m MS shall be able to operate with
16e BS with the same performance as
16e MS (b=d)
⑥ 16m shall provide the ability to
disable legacy support (e only)

Resources (time, frequency, space, code, etc.) can be divided for 802.16e and 802.16m
Should not degrade performance of 802.16e
Should provide performance/functional improvement for 802.16m
Should support migration scenario
802.16e-only functions/features can only be disabled when there is no legacy system in the
market

Maintain OFDMA numerology identical in new and legacy zones when both new and
legacy systems are deployed on the same RF carrier.
Maintain radio frame size identical for both systems.
Maintain compatible downlink and uplink multiple access technologies for both
systems.
Use of new and non-interoperable functions is only permissible in the new zones.
New synchronization channel, common control channel, and broadcast information
may be used in the new zones.
Layer 1 and Layer 2 protocol enhancements that affect backward compatibility are
limited only to the new zones.
