Publication number: 20220167422Abstract: A technique of accounting for the difference in required output power reduction or required duty cycle when selecting the RO in addition to the DL RS. Both output power reduction and duty cycle are independently determined by UE itself (i.e., UE needs to be able to determine itself required power backoff and/or duty cycle in order to meet RF exposure requirements). Advantageously, a RACH procedure in which the UE determines both output power reduction and duty cycle independently enables better choices of output power reduction and duty cycle, enhancing data activity and coverage.Type: ApplicationFiled: April 15, 2020Publication date: May 26, 2022Inventors: Sami-Jukka Hakola, Jorma Kaikkonen, Timo Koskela, Lars Dalsgaard, Juha Karjalainen, Mihai Enescu
