Priority-Based Coexistence Management in IEEE 802.19-16/0153r0
This document discusses the proposal for priority-based coexistence management within IEEE P802.19.1a to enhance spectrum utilization efficiency. It addresses the increasing number of mobile devices and the need for fine-grained resource allocation to accommodate diverse channels and network demands. The solution involves sorting operation frequencies based on prospective interference levels to prioritize high-priority GCOs, ensuring effective spectrum allocation.

September 2016 doc.: IEEE 802.19-16/0153r0 Abstract This document proposes priority based coexistence management for IEEE P802.19.1a in order to improve efficiency of the spectrum utilization. Submission Slide 2 Chen SUN, Sony
September 2016 doc.: IEEE 802.19-16/0153r0 Motivation: Why we need priority based coexistence management PCAST indicates The number of mobile devices could rise to 50 billion by 2020 One of the other important directions that spectrum policy must take is to create a marketplace that can accommodate the widest range of commercial users [1] o We need to accommodate the large number of devices/networks. Due to the distribution variety of the channels in use, for a certain GCO, the available channels have different impact to current system performance as well as succeeding resource allocation. To accommodate more GCOs raises the need of fine-grained resource allocation, which prioritizes available spectrum considering the prospective impact of their usage to the system capacity. No resource allocation considering such variety of channel use in IEEE P802.19.1a so far. Slide 3 Submission Chen SUN, Sony
September 2016 doc.: IEEE 802.19-16/0153r0 Example scenario CM manages GCOs with different priorities (high/low). New entrant low-priority GCO requires channel. Given interference tolerance for the high priority GCO, the lower interference is caused, the more low priority GCO will be accommodated. Fig 1. Example Problem Submission Slide 4 Chen SUN, Sony
September 2016 doc.: IEEE 802.19-16/0153r0 Solution The priority based resource allocation could be launched by CM in the condition that there has no interference-free available frequency for the target GCO. Prospective interference level: the amount of interference that would be caused by the allocation of that particular frequency to be used by the target GCO. CM sorts the recommended operation frequencies to be used by target CGO in decreasing order of its prospective interference level to high priority GCO operating on the same channel. GCO estimates sequentially if the selected frequency can satisfy the GCO s SINR requirement. GCO feedbacks the information of new operating frequencies to CM for further coexistence discovery Fig 1. Example Solution Submission Slide 5 Chen SUN, Sony
September 2016 doc.: IEEE 802.19-16/0153r0 Flowchart Start (P#1) Coexistence discovery CDIS operation CM operation (P#2) Calculate prospective interference level on available frequencies caused by its usage of the target GCO to higher priority GCOs (P#3) Rank available frequencies according to their interference level for the target GCO (P#4) Send the ranking result of ordered available frequencies to the target GCO or to another CM CM operation CE operation (P#5) Send ranking result to GCO and report GCO s frequency selection result to CDIS Submission Slide 6 Chen SUN, Sony
September 2016 doc.: IEEE 802.19-16/0153r0 Conclusion Priority based coexistence management is able to reduce interference from low priority GCO to high priority GCO Priority based coexistence management scheme as well as related data, procedure, message should be introduced into IEEE 802.19.1a system Submission Slide 7 Chen SUN, Sony
