13.1 Introduction
Positioning has so far been an add‐on feature to mobile phone standards. Wireless positioning typically relies on power‐hunger technology and has traditionally been designed and optimized separately from the communication part. With the advent of 5G communications, this is likely to change and joint communication‐positioning architectures based on 5G are expected to be implemented. The official 3GPP target for future cellular networks is to support 1 trillion devices [3]. The 5G concept is based on dense access point deployment and very large bandwidths, and thus it has an intrinsic capacity to achieve very accurate positioning, at extremely low energy consumption in mobile device. However, this requires a careful design of the 5G network in order to utilize fully this positioning potential without a negative impact on the communications features. The top candidates in future 5G positioning are likely to rely on Time of Arrival (TOA), Time Difference of Arrival (TDOA), Direction or angle of Arrival (DOA), and Received Signal Strength (RSS) information. 5G white papers [3,81] specify that the enhanced 5G services ...
