Very helpful Mr Rahim. Is it possible to have Mac NR CA IN FR1, Mac NR CA in FR2 together with NR-DC? Thank you

[@RahimNavaei]

Thank you for your comment. As you know, in NR-DC configuration, the PDCP layer at the Secondary Node (SgNB) is responsible for splitting the incoming packets from the UPF. Consequently, we have two paths for sending and receiving user packets. One path utilizes the SCG (Secondary Cell Group) resources, while the other employs MCG (Master Cell Group) resources. For both paths, Carrier Aggregation (CA) can be utilized by the MgNB and SgNB to transmit and receive user packets."
Carrier Aggregation (CA) allows for the use of multiple carriers or bands to increase the bandwidth and thereby the data rate for the user. In the context of NR-DC, CA can be applied to both MCG and SCG bearers to optimize the use of radio resources and improve network performance.
