When the gNB receives the RQI and QFI from UPF, it\u2019ll indicate it to the UE, so the UE will just monitor the header and once RQI is set, so it\u2019ll apply same QoS in DL to all UL data packets transmission with no specific signaling to tell the UE which QoS will be used in UL.<\/p>\n<p><em>My friend:<\/em> Thanks a lot.<\/p>\n<p><em>Me:<\/em> You are welcome.<\/p>\n<p>Please share arround you to clear it for everyone, and have a look to our last articles<\/p>\n<!-- \/wp:post-content -->\n\n<!-- wp:paragraph -->\n<p><em>Source: Ibrahim Sayed<\/em><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p><em>Linkedin Profile:\u00a0<a href=\"https:\/\/www.linkedin.com\/in\/ibrahim-sayed-88a7747-5g\/\">https:\/\/www.linkedin.com\/in\/ibrahim-sayed-88a7747-5g\/<\/a><\/em>\u00a0<\/p>","protected":false},"excerpt":{"rendered":"<p>My friend: Hi Ibrahim, I have a question for you.
