PHR METHOD AND APPARATUS FOR TRIGGERING AND CANCELING POWER HEADROOM REPORT PHR IN SMALL DATA TRANSMISSION PROCEDURE IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus are disclosed. In an example from a User Equipment (UE) perspective, the UE triggers a Power Headroom Report (PHR) when the UE is in a Radio Resource Control (RRC) inactive state. The UE determines whether to cancel the PHR based on whether the uplink (UL) resource for transmission in the RRC inactive state can accommodate the first reserved data available for transmission.
