IEEE DCN Submission Abstract This contribution presents an overview of coexistence use cases and classification that can be useful to generate evaluation criteria of coexistence Dependent services and independent services –Dependent services address the situation where LAN provides range extension of RAN for one service. LAN-LAN scenario –LAN-LAN scenario use cases Non-mobile user; Mobile user RAN-RAN scenario –RAN-RAN scenario use cases Non-mobile user; Mobile user LAN-RAN scenario –LAN-RAN scenario use cases Coexistence table of LAN-RAN scenario Classification of devices based on mobility Note: The use cases address the coexistence among heterogeneous networks or networks operated by different operators. LAN and RAN services can be considered of providing coverage extension or of different service purposes. End user devices can have direct access to RAN services instead of using LAN services as a “bridge”. January Slide 2Chen Sun et al, NICT

IEEE DCN Submission LAN-LAN coexistence scenario In a typical LAN service area different LAN of different wireless technologies might exist. For example, in a city business district different service providers might provide LAN access based on different technologies (e.g., , , etc) using TVWS (for example in near by buildings or in same building). Slide 4Chen Sun et al, NICT January

IEEE DCN Submission LAN-LAN coexistence scenario, use cases Use case 1: non-mobile user –TVWS devices such as computers having LAN access –Mode I, Mode II, sensing-only devices Use case 2: mobile user –TVWS devices such as moving pedestrians having LAN access –Mode I, Mode II, sensing-only devices Slide 5Chen Sun et al, NICT January

IEEE DCN Submission RAN-RAN coexistence scenario In a typical RAN service area, different RAN of different wireless technologies might exist. For example, different towns provide different RAN access to residents based on different technologies (e.g., , , etc) using TVWS. At the border area of towns the RAN-RAN coexistence issue arises.

IEEE DCN Submission RAN-RAN coexistence scenario, use cases Use case 1: non-mobile user –TVWS devices such as CPEs having RAN access –fixed; Mode I Use case 2: mobile user –TVWS devices such as pedestrian devices, vehicles, trains having RAN access –Mode I Slide 7Chen Sun et al, NICT January

IEEE DCN Submission LAN-RAN coexistence scenario For coverage extension, RAN services provide connection over large area whereas LAN services provide access for end users. RAN services provide backbone connection to network such as from local base stations/CPEs to backbone internet. LAN services provide connection at end users such as from PCs/PDAs to access points/CPEs Slide 8Chen Sun et al, NICT January

IEEE DCN Submission LAN-RAN coexistence scenario, Use case 2: University campus Scenario description –TVWS RAN provides internet access to university campus through a local/regional base station (for extra capacity or due to infrastructure incapability). –TVWS RAN can also provide end user devices with direct connection to Internet. –TVWS LAN provides internet access to students’ computers and PDAs (notice the transmit power limit of the portable devices). Devices –Base station (fixed; 4w) –CPE (Mode I) –Campus access point in LAN (Mode II) –Campus devices in RAN (mode I) –Sensing-only devices for short range applications Slide 10Chen Sun et al, NICT January
