2 Abstract This presentation provides supporting materials to a new requirement of uplink heavy data service proposed for IEEE n in IEEE C80216_10/0066r2

3 Motivation As stated in n PAR [1], Furthermore the target applications are associated with a wide range of users such as public safety agencies (e.g.Police, firefighters and Emergency Medical Services), industrial and construction companies, utilities and transport (e.g. bus, rail, airport, harbor) providers and government organizations. Uplink video streaming is required in PPDR/PBB applications, e.g., to transmit disaster/accident field video to command centre. It is required the uplink is capable of using more bandwidth than downlink when necessary.

4 Video streaming is needed in PPDR and PBB Application

5 Calculation of Video Data Rate Video types – Standard DV: 720×480 – HDV 720p: 1280×720 – HDV 1080i: 1440 ×1080 Video data rate calculation method – Data rate = W×H ×BPP ×FPS – W is width, H is height, BPP is bit per pixel after compression, FPS is frame per second – BPP = CD/CF, CD is color depth, e.g., 8 bit/pixel, CF is compress factor, e.g., 32:1, then BPP = 8/32 = 0.25

6 DV & HDV Data Rate DV resolution: 720×480 HDV resolution: HDV 720p (1280×720), HDV 1080i (1440×1080) Codec: MPEG-4 (BPP = 0.25) Frames per second: 30 Data rate: – Standard DV: 720 ×480 ×0.25 ×30 /1024 /1024 = Mbps – HDV 720p: 1280×720×0.25×30 /1024/1024 = 6.6 Mbps – HDV 1080i: 1440×1080×0.25×30/1024/1024 = 11.2 Mbps

7 DL/UL Ratio in standards – Not specified – In WiMAX, it is specified: 26:21 to 35: m – The DL/UL ratio is specified: 3:5, 4:4, 5:3, 6:2, 8:0 S5 S4 S3 S2 S1 S0 TDD Frame: 5ms DL SF0(6) UL SF3(6) DL SF1(6) DL SF2(5) UL SF4(6) UL SF5(6) UL SF6(6) UL SF7(6) Superframe: 20ms SU0SU1SU2SU3 F0F1F2 F3 Fig. 1 Frame structure of m

9 802.16m Uplink Data Rate Uplink data rate of 16m with DL/UL 3:5 = 6.12 Mbit/s, with other parameters: -Channel Bandwidth: 5 MHz (Japanese PBB system in 200MHz band) -FFT size: 512 (Frame length = 5ms) -number of effective sub-carriers: 408 -Cyclic Prefix : 1/8 (to cover up to 10 usec-delayed wave) – Modulation and Coding Scheme: 16QAM-CTC3/4 – Pilot Pattern (UL): left figure below (pilot occupancy: 1/6)

10 Uplink Rate with Modified DL/UL Ratio in m Same parameters used as DL/UL of 3:5, if we use lower DL/UL ratio, we can have higher uplink data rate in m (if other parameters do not change) – If DL/UL=3:5, the uplink data rate is 6.12 Mbit/s – If DL/UL=2:6, the uplink data rate becomes Mbit/s – DL/UL=1:7, the uplink data rate becomes Mbit/s

11 Number of uplink video streaming supported by /802.16m – A Comparison (Channel is 5 MHz) technologyStandard DV (2.472Mbps) HDV 720p (6.6Mbps) HDV 1080i (11.2Mbps) with DL/UL of 26:21 (2.9Mbps) with DL/UL of 9:38 (5.7Mbps) with DL/UL of 9:38 and modified tile (7.4Mbps) m with DL/UL of 3:5 (6.12Mbps) m with DL/UL of 2:6 (7.34Mbps) m with DL/UL of 1:7 (8.57Mbps) 3 10

12 Options for Chip Manufactures OptionsAdvantageDisadvantage with DL/UL of 26:21 (2.9Mbps) No change of chip design Loss market of HDV UL support; very limited DV support with DL/UL of 9:38 (5.7Mbps) More UL DV transmission is supported Change of chip design may need. Loss market of HDV UL support with DL/UL of 9:38 and modified tile (7.4Mbps) Even more UL DV support; HDV UL supported Change of chip design is required m with DL/UL of 3:5 (6.12Mbps) UL DV transmission is supported; no need to change chip design Loss of HV market m with DL/UL of 2:6 (7.34Mbps) Both DV and HDV are supported May need to change IC design m with DL/UL of 1:7 (8.57Mbps)

13 Text proposal for 16n SRD Uplink Heavy Data Service The HR-Network MAC shall be able to support uplink heavy data service for supporting uplink video steaming for surveillance, PPDR and other applications. To support this service, low downlink to uplink (DL/UL) ratio is required. For example, when channel bandwidth is 5 MHz, at least 9:38 (DL/UL ratio) in WirelessMAN-OFDMA based system or 2:6 (DL/UL ratio) in WirelessMAN-Advanced Air Interface based system is required.
