Month Year doc.: IEEE 802.11-yy/xxxxr0 Sept 2013 Abstract This proposal describes the Interference scenarios within EUHT networks, and the co-existence scenario of IEEE - 802.11 based WLAN and EUHT networks The presentation provides the interference management issues for EUHT networks The presentation shows the co-existence scenarios for IEEE 802.11 and EUHT Liu Shenfa et al (Nufront) John Doe, Some Company

Month Year doc.: IEEE 802.11-yy/xxxxr0 Sept 2013 Introduction EUHT has been published as Chinese industrial standard in Feb, 2012 EUHT can be used in 2.4GHz or 5.8GHz ISM band 5GHz band : 5150~5350 MHz Open for systems with tx power < 200mW, indoor applications only 5470 ~ 5725 MHz Still under discussion 5725 ~ 5850 MHz Apply before deployment Liu Shenfa et al (Nufront) John Doe, Some Company

Interference management in EUHT networks Sept 2013 Interference management in EUHT networks Multichannel OFDM is used on the EUHT PHY Large number of CAPs / STAs is expected in EUHT network Interference management issue is important with the increasing “cells” in EUHT networks Two Interference Scenarios are presented. Interference between synchronized EUHT Systems Interference between non-synchronized EUHT Systems Liu Shenfa et al (Nufront)

Interference between synchronized EUHT Systems Sept 2013 Interference between synchronized EUHT Systems Synchronized EUHT cells with the same frequency have interference between home CAP and neighbor STA Liu Shenfa et al (Nufront)

Interference between non-synchronized EUHT System Sept 2013 Interference between non-synchronized EUHT System Non-Synchronized EUHT cells with the same frequency have interference between home CAP and neighbor STA , and between the CAPs and STAs belongs to different cells.

Coexistence Scenario of IEEE 802.11 and EUHT Month Year doc.: IEEE 802.11-yy/xxxxr0 Sept 2013 Coexistence Scenario of IEEE 802.11 and EUHT Co-existence interference analysis Liu Shenfa et al (Nufront) John Doe, Some Company

Interference between EUHT network and IEEE 802.11 network Sept 2013 Interference between EUHT network and IEEE 802.11 network The existence of EUHT network will decrease the successful rate of CSMA, and decrease the capacity of IEEE 802.11 network. Obviously, EUHT system will occupy more time slot. Liu Shenfa et al (Nufront)

Sept 2013 Conclusions Fairness concepts and policies are required for co-existence Currently, can’t guarantee good co-existence performance The typical interference scenarios in which IEEE 802.11 and EUHT systems are operated on the same and adjacent frequency bands need to be addressed Liu Shenfa et al (Nufront)
