This contribution presents the frame structure for relay added on to the basic frame structure. 2 IEEE 802.16m Access Network Architecture with Relay R1 R1 16m BS R6 R1 R8 16m MS R1 x 16m RS R1 y 16m BS R6 Access Service Network Gateway 16e MS R1 z 16m MS R1 x 16m RS Access Service Network Layer 1 and Layer 2 protocols to be specified by 802.16m standard Details given in contribution C802.16m-07/299r3 3 Consideration for Relay Frame Structure The frame structure should support the BS-RS link (R1 y) RS-RS link (R1 z) and RS-MS link (R1 x). The RS-MS link should support both legacy MS and 16m MS The hop-to-hop latency should be minimized to meet the latency requirements defined in IEEE 802.16m SRD 4 Relay Frame Structure for Single Band Operation (1/2) DL sub-frame UL sub-frame DL sub-frame UL sub-frame BS DL Access Zone mini-slots (BS- MS) DL relay Zone mini-slots (BS- RS) UL Access Zone mini-slots (MS- BS) UL Relay Zone mini-slots RS 1 DL access zone mini-slots (RS- MS) Global Rx Zone mini-slots (RS receives from parent/child) UL Access Zone mini-slots (MS- RS) Global Tx Zone mini-slots (RS transmits to parent/child)) RS 2 DL access zone mini-slots (RS- MS) Global Tx Zone mini-slots (RS transmits to parent/child) UL Access Zone mini-slots (MS- RS) Global Rx Zone mini-slots (RS receives from parent/child)) 16m preamble mini-slot:: contain 16m synchronization channel and 16m broadcast control channel legacy DL mini-slots zone: used for BS/RS to legacy MS transmission 16m DL mini-slots zone: used for relay link and for access link transmission to 16m MS legacy UL mini-slots zone: used for legacy MS to BS/RS transmission 16m UL mini-slots zone: used for relay link and for access link transmission from MS 5
