January 2016 doc.: IEEE 802.19-16/0019r0 Abstract This document provides the proposed changes on the current IEEE 802.19.1 standards for implementation of energy detection adjustment for coexistence management Submission Slide 2 Chen Sun, Sony China
January 2016 doc.: IEEE 802.19-16/0019r0 Background There is a potential that different wireless systems will operate in the same frequency band For example, the TV band, 3.5GHz in US and the 5GHz band These different wireless systems might use different radio access technologies. IEEE 802.19.1 or its enhanced system (802.19.1a) can manage these different wireless systems together for coexistence over IP-network. In many cases, most of these wireless systems employ functionality of energy detection CCA. Generally, it is obvious that the value of energy detection threshold affects the performance of wireless systems. In such case, there might be merit that we adjust the performance of the wireless systems by controlling the energy detection threshold over IP- network. In 802.19-15/0092r0[1] we have presented the simulation result of effect on the energy detection adjustment. Submission Slide 3 Chen Sun, Sony China
January 2016 doc.: IEEE 802.19-16/0019r0 Action item from the last F2F meeting[2] To provide a use case using this mechanism to understand how this mechanism effects the current IEEE 802.19.1-2014 systems architecture, procedures, messages, data types, and primitives. Submission Slide 4 Chen Sun, Sony China
January 2016 doc.: IEEE 802.19-16/0019r0 Use case Different operators have deployed different wireless network equipments at neighboring areas. Different operators may use different radio access technologies. For example, operator 1 uses TD-LTE and operator 2 uses Wi-Fi These systems employ energy detection before utilizing spectrum Different systems can employ different energy detection thresholds for determination of channel availability. A system with high detection threshold has a higher probability that it deems the channel is available than that of the system with a low detection threshold. Therefore, they have different spectrum utilization opportunities. In the management service, the centralized management entity can thus modify the detection threshold to adjust the spectrum utilization of different systems. Submission Slide 5 Chen Sun, Sony China
