2 2 IEEE C802.16j-07/409 A Proposal for Transmission of FCH, MAP, R-FCH, R-MAP in Nontransparnt Rlay Systm with Cntralizd Schduling Mary Chion, Jrry Chow, Hongyun Qu ZTE Introduction This contribution proposs a mchanism usd for MR-BS and RS to transmit th schduling information including FCH, MAP, R-FCH and R-MAP in non-transparnt rlay systm with cntralizd schduling. Dtails As w all know, rgarding non-transparnt RS with cntralizd schduling, MR-BS has to dtrmin th schduling and allocation of RS downlink subfram and uplink subfram. It mans MR-BS shall dtrmin th transmission paramtrs and allocation for DL/UL accss zon and rlay zon of RS fram. Th transmission paramtrs and allocation information includ FCH, DL/UL MAP for accss zon, and R-FCH, R-MAP and for rlay zon, whrin accss zon and rlay zon blong to th fram of RS. Whn non-transparnt RS with cntralizd schduling rcivs ths transmission paramtrs and allocation information, RS shall transmit FCH, DL/UL MAP in DL accss zon, and also transmit R-FCH, R-MAP in DL rlay zon as rquird by MR- BS. For non-transparnt rlay systm with cntralizd schduling, MR-BS has to dtrmin th schduling and allocation of all th rlay links and accss link for RSs in th rlay path. MR-BS shall transmit th schduling information of all th RSs in DL rlay zon of MR-BS fram. Aftr th first RS rcivs ths schduling information, th first RS shall transmit FCH, DL/UL MAP in DL accss zon, and also transmit R-FCH, R- MAP in DL rlay zon as rquird by MR-BS. And th first RS shall also forward th schduling information for othr RSs in th rlay path in DL rlay zon as indicatd by MR-BS. Othr intrmdiat RSs shall do th sam opration as th first RS. And th accss RS only broadcast FCH, DL/UL MAP in DL accss zon as indicatd by th rcivd schduling information from suprordinat RS or MR-BS. In currnt 16j baslin, thr is no a complt mchanism to dscrib how MR-BS transmit ths schduling information for non-transparnt RS with cntralizd schduling in MR-BS DL rlay zon. To rsolv th abov mntiond problm, w propos a nw RS Schduling MAP mssag in which all th information, including FCH, DL/UL MAP for accss zon and R-FCH, R-MAP for rlay zon, should b includd for individual non-transparnt RS with cntralizd schduling. This RS Schduling MAP mssag shall b gnratd by MR-BS and b snt in DL rlay zon. Non-transparnt RS with cntralizd schduling shall rcompos and broadcast FCH, DL/UL MAP in DL accss zon, and broadcast R-FCH, R-MAP in DL rlay zon according to th rcivd RS Schduling MAP mssag. And RS also nds to forward RS Schduling MAP mssag for othr non-transparnt RSs with cntralizd schduling in th rlay path as rquird by MR-BS. In addition, bcaus MR-BS has to do th schduling for non-transparnt RS with cntralizd schduling for ach fram, if vry tim RS Schduling MAP mssag contains all th schduling information and configuration information, it will caus vry larg ovrhad. So w also propos to includ only changd configuration information in RS Schduling MAP mssag and priodically broadcast all th configuration information.

This mssag contains allocation information for RS and shall b snt onc pr fram ovr RS basic connction. Aftr th rcption of RS Schduling MAP mssag, RS shall compos FCH, DL/UL MAP, R-FCH, R-MAP basd on its RS Schduling MAP mssag and othr rlatd configuration mssags. RS shall transmit FCH, DL/UL/MAP in RS DL accss zon, and transmit R-FCH, R-MAP in RS DL rlay zon.
