Month Year doc.: IEEE 802.11-yy/xxxxr0 May 2015 Abstract This submission provides updated simulation results for Box-5 calibration and reviews our Box-5 calibration work Suhwook Kim, LG Electronics John Doe, Some Company

Box-5 Calibration [1] Box 0, 1, and 2 calibration are almost done May 2015 Box-5 Calibration [1] Box 0, 1, and 2 calibration are almost done Box 3 calibration is now in progress Box 5 calibration was initially discussed in September meeting Box 5: Integrated system simulator calibration The objective is to align a combination of all PHY and MAC features Suhwook Kim, LG Electronics

Box-5 PHY Details [2] May 2015 PHY parameters BW All BSSs at 5GHz [80 MHz, no dynamic bandwidth] Channel model TGac D NLOS per link Shadow fading iid log-normal shadowing (5 dB standard deviation) per link Data Preamble Type [5GHz, 11ac], always decoded correctly after successful reception, duration is considered. STA TX Power 15 dBm per antenna  AP TX Power 20 dBm  per antenna AP number of TX/RX antennas 1/1 STA number of TX /RX antennas AP antenna gain 0 dBi STA antenna gain -2 dBi Noise Figure 7dB CCA threshold -56 dBm (measured across the entire bandwidth after large-scale fading) Rx sensitivity -76 dBm (a packet with lower rx power is dropped) Link Adaption Fixed MCS =5 (234.0 Mbps) Channel estimation ideal PHY abstraction RBIR, BCC [1, 5] Channel correlation Independent or time-correlated channel per packet Suhwook Kim, LG Electronics

Box-5 MAC Details [2] May 2015 MAC parameters Access protocol [EDCA, AC_BE with default parameters] [CWmin = 15, CWmax = 1023, AIFSn=3 ] Queue length A single queue for each traffic link is set inside AP/STA sized of 2000 packets Traffic type UDP CBR with rate 10^8bps (may not enough to model full buffer) MPDU size 1540 Bytes (1472 Data + 28 IP header + 40 MAC header) Aggregation [A-MPDU / max aggregation size / BA window size, No A-MSDU, with immediate BA], Max aggregation: 64 MPDUs with 4-byte MPDU delimiter Max number of retries 10 Beacon Disabled RTS/CTS OFF Traffic direction UL Only Output metric -CDF or Histogram of per non-AP STA throughput (received bits/overall simulation time) -PER of all AP/STA (1 - # of success subframes / # of transmitted subframes) Suhwook Kim, LG Electronics

History on Box-5 Calibration May 2015 History on Box-5 Calibration We have discussed Box-5 calibration from September meeting Many issues have been agreed and addressed in DCN 1523r5 However, we still found big performance difference among members Simulator members agreed that we have to focus on 1 BSS UL case in March meeting (BSS B) Suhwook Kim, LG Electronics

Focusing case No shadowing Fixed MCS = 5 instead of 7 currently used May 2015 Focusing case No shadowing Fixed MCS = 5 instead of 7 currently used Firstly calibrate 3 combinations of 2-STA case (3+9, 3+27, 3+15) Then we turn to 3-STA case (3+9+27, 3+9+15) Suhwook Kim, LG Electronics

One BSS Test Result BSS B (STAs 3, 9, 15, 21, 27) May 2015 One BSS Test Result BSS B (STAs 3, 9, 15, 21, 27) UL only, UDP CBR with rate 10^8bps Throughput [Mbps] PER 2 STAs STA 3, STA 9 STA 3: 98.25 STA 9: 98.13 11.2% 11.0% STA 3, STA 27 STA 3: 91.02 STA 27: 94.19 17.8% 17.2% STA 3, STA 15 STA 3: 98.36 STA 15: 98.95 9.7% 3 STAs STA 3, STA 9, STA 27 STA 3: 65.66 STA 9: 65.49 STA 27: 55.61 18.9% 18.4% 23.5% STA 3, STA 9, STA 15 STA 3: 60.16 STA 9: 62.89 STA 15: 66.01 19.6% 19.3% Suhwook Kim, LG Electronics

May 2015 Conclusion In this submission, we provided updated simulation results for Box 5 calibration We focused on 1 BSS UL case Suhwook Kim, LG Electronics
