“…The mm-wave channel can be characterized with few parameters by means of stochastic geometrical channel models (SGCM), which have become an attractive approach, given the propagation behavior of mm-wave where the lineof-sight (LOS) and a few dominant multipath components contribute to the received power [11]- [15]. SCGMs relate the propagation to the geometry of the operating scenario, thus creating an interplay between the communication channel and the positions of the transmitter and receiver, as well as the environment [11]- [15]. On one hand, the positions of devices can be estimated through the exchange of mmwave signals, which in turn requires the establishment of a communication link [16], [17].…”

Millimeter-wave (mm-wave) and massive multiple-input-multiple-output technologies appear as key enablers in future emerging wireless communication systems. Propagation in mm-wave communications is well described by geometric channel models, where a clear relation between communication and positioning arises. On one hand, initial access, a procedure that precedes high data rate transmission and consists of beam selection and alignment between two devices, can benefit from position information. On the other hand, accurate positioning relies on high-quality communication links with proper beam alignment. This work analyzes the interplay between communication and positioning, proposes a new in-band positionaided beam selection protocol considering scenarios with line-of-sight and reflected paths, and possible beam alignment errors. Simulation results show significant reductions in latency with respect to standard beam selection protocols.

“…Given the quasi-optical propagation of mm-wave, stochastic geometrical channel models have become an attractive approach to characterize the channel with few parameters. These models relate the propagation to the geometry of the operating environment, thus creating an explicit interplay between the communication channel and the positions of the transmitter, receiver, and reflectors [12]- [16]. This interplay becomes apparent during the initial access phase, where two devices, a transmitter and a receiver, here termed D1 and D2, aim to establish a connection by achieving beam alignment.…”

Emerging wireless communication systems will be characterized by a tight coupling between communication and positioning. This is particularly apparent in millimeter-wave (mm-wave) communications, where devices use a large number of antennas and the propagation is well described by geometric channel models. For mm-wave communications, initial access, consisting in the beam selection and alignment of two devices, is challenging and time-consuming in the absence of location information. Conversely, accurate positioning relies on highquality communication links with proper beam alignment. This paper studies this interaction and proposes a new positionaided beam selection protocol, which considers the problem of joint communication and positioning in scenarios with direct line-of-sight and scattering. Simulation results show significant reductions in latency with respect to a standard protocol.
