The major functions of the RRC protocol include connection establishment and release function… WebMar 10, 2024 · RRC manages measurement configuration. Most measurements are executed by Layer 1, although some may be at Layer 2. RRC does filtering on Layer 1 measurements. If filtered measurements meet reporting criteria, they're reported to the network. Some measurements are reported by Layer 1 directly to the network. royalty free dark backgrounds
