Purpose
 In SDD there are two options defined for the
RS frame structure namely option 1 and option
2. For the 2-hop relay system, the RS frame
structure for option 1 and option 2 are
identical. Therefore, we propose a 2-hop RS
frame structure. In addition, the transition GAP
can be omitted for the RS with dual
transceiver.
3+-hop frame structure
 For 3+-hop relay system, there are two options of
frame structures defined in current SDD.
– Unidirectional relay zone (option 1)
– Bidirectional relay zone (option 2)
 We proposed to adopt both options in SDD plus STR
relay frame structure. However, in order to avoid the
complexity of coexistence, we proposed that they
must not coexist in a 16m relay network. Option 1
and STR have been studied extensively in 16j. Option
2 has the benefits of scheduling efficiency, but it
requires detail technical design to resolve interference
and power management issues.
