Impact of Intra-Cluster Angular Spread on the Performance of NLoS Millimeter Wave Links With Imperfect Beam Alignment

Location-aided user selection and sum-rate analysis for mmWave NOMA

“…Hence the location information is not applied efficiently. Furthermore, studies [39], [40] have shown that due to the height of the BS, the channel angle spread observed at BS to the UEs is small. As a consequence, UEs can be clustered based on the line-of-sight (LOS) angle of departure (AOD) differences, where the AOD of the LOS path can be acquired from the location information.…”
