3. doc.: IEEE 802.11-14/1160r0 Submission Terminology [1]  Usage Model – A usage model is the combination of all the things below; not to be confused with a use case which is the specific set of steps to accomplish a particular task. Pre-Conditions – Initial conditions before the use case begins. Application – A source and/or sink of wireless data that relates to a particular type of user activity. Examples are streaming video and VoIP. Environment – The type of place in which the network of the use case is deployed, such as home, outdoor, hot spot, enterprise, metropolitan area, etc. Traffic Conditions – General background traffic or interference that is expected while the use case steps are occurring. Overlapping BSSs, existing video streams, and interference from cordless phones are all examples of traffic conditions. Use case – A use case is task oriented. It describes the specific step-by-step actions performed by a user or device. One use case example is a user starting and stopping a video stream. September 2014 Lei Huang, PanasonicSlide 3

5. doc.: IEEE 802.11-14/1160r0 Submission Why USR Communications Usage Models?  It is very natural for users standing just in front of kiosk (e.g., ATM, vending machine) or tollgate (e.g., train gate) to engage USR communications.  Due to ultra short link distance of USR communications,  mutual interference could be avoided among plural fixed devices (e.g., ATM, vending machine, train gates), which sometimes are located shoulder-by-shoulder or in close proximity.  NG60 PHY/MAC protocols (e.g., BF, security, etc.) could be simplified to reduce power consumption of portable/mobile devices.

6. doc.: IEEE 802.11-14/1160r0 Submission Usage Model 1a: USR Mass Data Download/Upload Traffic Conditions: Only a single portable/mobile device can access to a fixed device at a time with simply best-effort rates. There is typically no interference from other mm- wave links due to ultra short link distance. Traffic is typical unidirectional. Use Case: 1.User places a portable/mobile device in a definite position relative to a fixed device. 2.User completes secure pairing between the portable/mobile device and the fixed device with minimal user configuration. 3.User launches the desired application and starts the desired task (e.g., download movie). 4.User exits the application when task is complete. Pre-Conditions: User has WLAN connectivity between a portable/mobile device (e.g., tablet, smart phone) and a fixed device (e.g., kiosk, PC). Application: Users can transfer mass data (e.g., movies, video/audio clips and picture library, etc.) between a portable/mobile device and a fixed device. An HD movie of 5GB takes 5.7 seconds over a single hop 10Gbps link. Jitter and delay are not critical. The key metric is the user’s time spent to do a transfer. Less than 10 seconds is acceptable. 10-60 seconds may be acceptable. More than 1 minute may not be acceptable. Environment: Environments can be variable, e.g., crowded public space such as train stations, airports, shopping mall, office, or a single home. Link distance can typically be up to 10 cm. Typically transmissions are Line of Sight. All devices will typically be stationary during usage. September 2014 Lei Huang, PanasonicSlide 6

7. doc.: IEEE 802.11-14/1160r0 Submission Usage Model 1b: USR Peer-to-Peer Device Sync Traffic Conditions: Simply best-effort rates. There is typically no interference from other mm-wave links due to ultra short link distance. Traffic is typically symmetric and bidirectional. Use Case: 1.Users align the two portable/mobile devices toward each other. 2.User completes secure pairing between the two portable/mobile devices with minimal user configuration. 3.User launches the desired application and starts the desired task (e.g., sync files). 4.User exits the application when task is complete. Pre-Conditions: Users have WLAN connectivity between two portable/mobile devices (e.g. tablet, smart phone, camera, etc.). Application: Portable/mobile devices users can share mass data such as movies, video/audio clips, picture library, etc. with each other in seconds. An HD movie of 5GByte takes 5.7 seconds over a single hop 10Gbps link. The key metric is the user’s time spent to do a transfer. Less than 10 seconds is acceptable. 10-60 seconds may be acceptable. More than 1 minute may not be acceptable. Environment: Environments can be variable, e.g., crowded public space such as train stations, airports, shopping mall, office, or a single home.

8. doc.: IEEE 802.11-14/1160r0 Submission Usage Model 1c: USR Touch-and-Get Traffic Conditions: Only a single portable/mobile device can access to a fixed device at a time with simply best-effort rates. There is typically no interference from other mm-wave links due to ultra short link distance. Traffic is unidirectional. Use Case: 1.User places a portable/mobile device in a definite position relative to a fixed device. 2.Secure pairing between the portable/device device and the fixed device is completed without user configuration. 3.The pre-selected application is launched and the pre-selected task (e.g., download video clip) is started. 4.The application exits when task is complete. Pre-Conditions: User has WLAN connectivity between a portable/mobile device (e.g., tablet, smart phone) and a fixed device (e.g., tollgate, kiosk). Application: Users can download mass data (e.g. video/audio clip, e-magazine, picture library etc.) from a fixed device. 100 jpeg (picture) files of 5MB takes 0.6 second over a single hop 10Gbps link. Jitter and delay are not critical. The key metric is the user’s time spent to do a transfer. Less than 1 second is acceptable. 1-5 seconds may be acceptable. More than 5 seconds may not be acceptable. Environment: Environments can be variable, e.g., crowded public space such as train stations, airports, shopping mall, office. Link distance can typically be up to 10 cm. Typically transmissions are Line of Sight. All devices will typically be stationary during usage. September 2014 Lei Huang, PanasonicSlide 8
