The objective of this paper is to provide details on the methodology and results from these simulation studies. The results of the simulation studies conducted across ten global cities, show that significant outdoor downlink coverage (up to 81%) is possible when co-siting 5G NR mmWave with existing 4G LTE macro and small cell sites. The positive results show that mobile deployments in urban-areas based on existing LTE cell cities is feasible, especially when considering the tight-interworking of 5G NR with 4G LTE.
Although mmWave outdoor-to-indoor coverage for mobile is not feasible, the outdoor mmWave coverage will significantly free up resources in the spectrum bands below 6 GHz for outdoor-to-indoor capacity, utilizing either 4G LTE or 5G NR technology. In addition, outdoor mmWave coverage can be complemented with targeted indoor mmWave deployments. An example coverage simulation for a large indoor venue is also included in the paper.
The paper will also provide some background on the key properties for robust 5G NR mmWave operation in a non-line-of-sight (NLOS) mobile environment, as well as showcase how Qualcomm Technologies is leading the way to mobilize 5G NR mmWave and make it a commercial reality in 2019.
