Samsung patents method to split 4G and 5G signals on same frequency
This patent describes a way for mobile networks to share the same radio frequency between older 4G (LTE) and newer 5G (NR) signals. The system checks how busy each network is and adjusts the split of resources to keep both connections running smoothly without one crowding out the other.
In the filing’s own words
The disclosure relates to a 5 th generation (5G) or 6 th generation (6G) communication system for supporting a higher data transmission rate. A method and a network entity for dynamic spectrum sharing (DSS) between long term evolution (LTE) cell and new radio (NR) cell in a wireless network are provided. The method includes determining a plurality of DSS parameter, determining a resource split between at least one bearer of a plurality of bearers of the LTE cell and at least one bearer of a plurality of bearers of the NR cell based on the plurality of DSS parameters, determining optimal key performance indicator (KPI) parameters for an overlapped LTE cell and NR cell combination based the resource split, and applying optimal tuning parameters on the overlapped LTE cell and NR cell combination in the wireless network based on the optimal KPI parameters.
What exactly they claim (claim 1)
1. A method performed by a network entity in a wireless network, the method comprising: determining a plurality of dynamic spectrum sharing (DSS) parameters for sharing of resources of a same carrier between a long-term evolution (LTE) cell and a new radio (NR) cell, wherein the plurality of DSS parameters includes information on a buffer occupancy (BO), a modulation and coding scheme (MCS), and a packet delay budget (PDB); determining an allocation of physical layer resources between the LTE cell and the NR cell based on the plurality of DSS parameters; determining a fairness index for maintaining fairness among a plurality of bearers of the LTE cell and a plurality of bearers of the NR cell based on the determined allocation of physical layer resources, accumulated transport block sizes for the LTE cell and the NR cell, and guaranteed bit rates (GBR) for the LTE cell and the NR cell; determining key performance indicator (KPI) parameters based on the fairness index, throughput associated with the LTE cell and the NR cell and interference associated with the LTE cell and the NR cell; and allocating physical layer resources between the LTE cell and the NR cell based on the KPI parameters.
