  1. Calibration of MAC simulator with OBSS Network Scenario Authors: Date: 2014-07-14 Chao-Chun Wang (MediaTek)

  2. 14/0621 r4 lists five MAC simulator calibration scenarios • All five cases measure the throughput of 20MHz channel with one or two BSSs • 11ax network will consists of 11ax STAs and legacy 11b/g/n/ac STAs • The simulation will have to address the cases that there are STAs and BSSs operating with different channel bandwidth • It is beneficial for MAC Calibration to include cases to evaluate the performance of BSSs operate with different channel bandwidth Summary Chao-Chun Wang (MediaTek)

  3. Same MAC and PHY Parameters are specified in 14/0621 r4 • The two BSSs has different channel bandwidth, one is 20MHz and another one is 40 MHz • The goal is verified that simulators have the same baseline MAC behavior and throughput. • The metrics for evaluation may include but not limit to check points, throughput Proposal Chao-Chun Wang (MediaTek)

  4. The set up and configuration is the same as test case 2a • If packets collide, the both transmission fail • The first BSS operates in 40 MHz channel • The second BSS operates in a 20MHz channel which is the secondary channel of the first BSS • With no channel model, the collision detection is determined by time domain information • Any overlapping MPDU is considered a failure • The secondary channel is consider free if there is no transmission on the secondary channel for PIFS • The 40MHz BSS is running full buffer. • The 20MHz BSS traffic is based on the Weibull distribution • 2Mbps traffic, lamda = 695, k=0.8099 • The results other than throughput and PER of each BSS also include • The percentage of time the 40MHz BSS running in 40 and 20 MHz mode. Deferral test for network of different channel bandwidth AP2 AP1 BSS_1 BSS_2 STA2 STA1 Chao-Chun Wang (MediaTek)

  5. Do you agree to include the proposed test case on page 4 in the simulation calibration scenario document? • Y • N • Abs Straw Poll Chao-Chun Wang (MediaTek)
