Description

Calibration of sensing radio frequency measurement information Background 1. Technical field Aspects of the present disclosure relate generally to wireless technology. 2. Description of related Art Wireless communication systems have evolved over many generations including first generation analog radiotelephone services (1G), second generation (2G) digital radiotelephone services (including transitional 2.5G and 2.75G networks), third generation (3G) high speed data, internet-capable wireless services, and fourth generation (4G) services (e.g., long Term Evolution (LTE) or WiMax). Many different types of wireless communication systems are currently in use, including cellular systems and Personal Communication Services (PCS) systems. Examples of known cellular systems include the cellular analog Advanced Mobile Phone System (AMPS), as well as digital cellular systems based on Code Division Multiple Access (CDMA), frequency Division Multiple Access (FDMA), time Division Multiple Access (TDMA), global system for mobile communications (GSM), and the like. The fifth generation (5G) wireless standard, known as New Radio (NR), achieves higher data transfer speeds, a greater number of connections, and better coverage, among other improvements. According to the next generation mobile network alliance, the 5G standard is designed to provide higher data rates, more accurate positioning (e.g., based on positioning reference signals (RS-P), such as downlink, uplink or sidelink Positioning Reference Signals (PRS)), and other technical enhancements than the previous standard. These enhancements and use of higher frequency bands, advances in PRS procedures and techniques, and high density deployment of 5G enable high accuracy positioning based on 5G.
