Performance Study of a GAA-GAA Coexistence Scheme in the CBRS Band

This research work is a performance study of GAA-GAA coexistence in the Citizens Broadband Radio Service (CBRS) band. The Wireless Innovation Forum (WINNForum), which has developed standards for commercial operations in this band, has recommended three approaches to GAA-GAA coexistence. This work studies one of the approaches (called Approach 1) . We provide the results of this study through the dataset archived here. There are few configurations considered in the study. We chose two geographical locations: Virginia Beach (VB) and San Diego (SD). In one deployment scenario all the CBRS devices (CBSDs) were chosen to be Category A (Cat A) CBSDs and in the other, it was a mix of Cat A and Cat B. CBSD deployment densities of 3, 10, 30, 50 per square kilometers were considered. Two propagation models, namely ITM and Hybrid models were used in the evaluation.

本研究针对公民宽带无线电服务（Citizens Broadband Radio Service, CBRS）频段内的GAA-GAA共存问题开展性能评估。为该频段商用运营制定相关标准的无线创新论坛（Wireless Innovation Forum, WINNForum），已针对GAA-GAA共存场景提出三种解决方案。本研究聚焦其中一种方案（即方案1），相关研究结果已通过此处归档的数据集对外发布。本次研究仅设置了少量配置场景：选取弗吉尼亚海滩（Virginia Beach, VB）与圣迭戈（San Diego, SD）两处地理位置；部署场景分为两类，一类为所有CBRS设备（Citizens Broadband Radio Service Device, CBSD）均为A类（Category A, Cat A）设备，另一类为A类与B类（Category B, Cat B）设备混合部署；同时考虑每平方公里3、10、30、50台的CBSD部署密度；评估过程中采用了ITM模型与混合（Hybrid）模型两种传播模型。
