2 Introduction Frame structure for talk-around direct communication (TDC) –Sync-Ch (synchronization channel)  IEEE C802.16n-11/0131 –Ded-Ch (dedicated channel) –Sup-Ch (supplementary channel) Ded-Ch –Channel for transmit data packets and control packets Sup-Ch –Channel for transmit associated messages (MAC message, PHY signaling, feedback message) for Ded-Ch –1:1 correspondence between a dedicated sub-channel and a supplementary sub-channel 2 This contribution

3 Frame structure for TDC Example. 3 uplink subframes/ 5msec frame –Synchronization Channel (Sync-CH): 1 st subframe of each superframe –Dedicated Channel(Ded-CH): 1 st subframe of the 2 nd and 4 th frame –Supplementary Channel(Sup-CH): the other subframes 3 A B A Sup-Ch for slot 2 Ded-Ch B Sup-Ch for slot 1 Ded-Ch

4 Resource segmentation for Ded-Ch and Sup-Ch mRB (mini-resource block) –6 subcarriers x 6 OFDM symbols –Each subframe for CDMZ is composed of 12 mRBs half-mRB –An mRB for Sup-Ch is divided into two half- mRB –One half-mRB is composed of 3 subcarriers x 5 OFDM symbols (6 th OFDM symbol is empty symbol) 4 mRBs for Ded-Ch mRBs for Sup-Ch

5 Dedicated Channel Dedicated sub-channel –Minimum allocation size of dedicated channel –One dedicated sub-channel is a set of 9 mRBs mRBs distributed across the entire frequency region in the same slot Number of dedicated sub-channels according to the number of uplink subframes in a frame Dedicated channel is used for transmitting data packets and control packets 5 The number of uplink subframes in a 5msec frame The number of dedicated sub- channel in the slot 1 The number of dedicated sub- channel in the slot 2 Total number of dedicated sub-channels 2336 35611 48917 511 22

6 Supplementary Channel Supplementary sub-channel –Each dedicated sub-channel has 1:1 correspondence with a supplementary sub-channel composed of two half-mRBs in the different slot Information transmitted by using the Sup-Ch –MAC messages: RTS, CTS, MCS information, ranging response et. al. –PHY signalings: periodic ranging sequence, sounding signal et. al. –Short feedback messages: ACK, NACK, CQI, CSI, RI (rank information) et. al. 6

7 Ded-Ch and Sup-Ch structure 2 UL subframes/ 5msec frame 7 subframe index mRB index - Ded-subchannel 3 and 6 cannot be assigned to the same TDC pair -Ded-subchannel 1 is composed of nine mRBs in the slot 1 (blue color) -Sup-subchannel 1 is composed of two half-mRBs (C1) in the subframe 7 (slot 2)

8 Ded-Ch and Sup-Ch structure 3 UL subframes/ 5msec frame 8 subframe index mRB index

9 Ded-Ch and Sup-Ch structure 4 UL subframes/ 5msec frame 9 subframe index mRB index

10 Ded-Ch and Sup-Ch structure 5 UL subframes/ 5msec frame 10 subframe index mRB index
