The method may include determining corresponding bandwidths for each frequency band, calculating a ratio of each bandwidth to a total bandwidth, and ranking each band based on bandwidth. The method may further include assigning wireless devices to the frequency bands based on the rankings of each band and the caps imposed on each band. ## Claims ### Claim 1 A method comprising: deploying multiple bands from a secondary node for a first radio access technology (RAT); determining a corresponding bandwidth for each of multiple bands; determining a total bandwidth for the multiple bands deployed for the first RAT; calculating a corresponding ratio for each band of each corresponding bandwidth to the total bandwidth for the multiple bands; ranking the bands based on the corresponding ratio; receiving a connection request from a wireless device using a second RAT for connection to the first RAT; and assigning the wireless device to one of the multiple bands for the first RAT based on the ranking. ### Claim 2 (depends on 1) The method of claim 1, further comprising receiving the connection request from the wireless device at a master node, the wireless device connecting to the master node using the second RAT. ### Claim 3 (depends on 2) The method of claim 2, wherein the master node is a long term evolution (LTE) master node operating in an evolved-universal mobile telecommunications service terrestrial radio access network (E-UTRAN) new radio—dual connectivity (EN-DC) environment. ### Claim 4 (depends on 2) The method of claim 2, wherein the first RAT is fifth generation (5G) new radio (NR). ### Claim 5 (depends on 3) The method of claim 3, wherein the wireless device is a new radio (NR) capable wireless device. ### Claim 6 (depends on 1) The method of claim 1, wherein a band having a highest bandwidth is ranked first and a band having a lowest bandwidth is ranked last and each other band is ranked sequentially based on the corresponding bandwidth. ### Claim 7 (depends on 6) The method of claim 6, further comprising imposing a corresponding cap for each band on a number of wireless devices assigned to the band based on the corresponding ratio for the band. ### Claim 8 (depends on 7) The method of claim 7, further comprising assigning each wireless device requesting a connection to the first ranked band until the corresponding cap for the first ranked band is reached. ### Claim 9 (depends on 8) The method of claim 8, further comprising assigning each wireless device requesting a connection to a second ranked band after the corresponding cap for the first ranked band is reached. ### Claim 10 (depends on 9) The method of claim 9, further comprising assigning each wireless device requesting a connection to a next ranked band after the corresponding cap for a previous band is reached. ### Claim 11 An access node comprising: at least one processor programmed for performing multiple operations, the operations including; determining a corresponding bandwidth for each of multiple bands deployed by a secondary access node for a first RAT; determining a total bandwidth for the first RAT; calculating a corresponding ratio for each band of each corresponding bandwidth to the total bandwidth for the first RAT; ranking the bands based on the corresponding ratio; receiving a connection request from a wireless device at the access node wherein the connection request is for connection using the first RAT; and assigning the wireless device to one of the multiple bands of the first RAT deployed by the secondary access node based on the ranking. ### Claim 12 (depends on 11) The access node of claim 11, wherein the access node is a long term evolution (LTE) master node operating in an evolved-universal mobile telecommunications service terrestrial radio access network (E-UTRAN) new radio-dual connectivity (EN-DC) environment. ### Claim 13 (depends on 12) The access node of claim 12, wherein the first RAT is fifth generation (5G) new radio (NR). ### Claim 14 (depends on 11) The access node of claim 11, wherein a band having a highest bandwidth is ranked first and a band having a lowest bandwidth is ranked last and each other band is ranked sequentially based on the corresponding bandwidth. ### Claim 15 (depends on 14) The access node of claim 14, the operations further comprising imposing a cap on a number of wireless devices assigned to each band based on the corresponding ratio for the band. ### Claim 16 (depends on 15) The access node of claim 15, the operations further comprising assigning each wireless device requesting a connection to the first ranked band until the cap for the first ranked band is reached. ### Claim 17 (depends on 16) The access node of claim 16, the operations further comprising assigning each wireless device requesting a connection to a next ranked band after the cap for a previous band is reached. ### Claim 18 A method comprising: determining a corresponding bandwidth for each of multiple bands deployed by an access node for a first RAT; determining a total bandwidth for the multiple bands deployed for the first RAT; calculating a corresponding ratio for each band of each corresponding bandwidth to the total bandwidth for the multiple bands; ranking each band deployed for the first RAT based on the corresponding bandwidth and imposing a corresponding cap for wireless devices connecting to each band based on the corresponding ratio; and assigning wireless devices to a highest ranked band until the corresponding cap is reached. ### Claim 19 (depends on 18) The method of claim 18, wherein a band having a highest bandwidth is ranked first and a band having a lowest bandwidth is ranked last and each other band is ranked sequentially based on the corresponding bandwidth. ### Claim 20 (depends on 19) The method of claim 19, further comprising assigning wireless devices to a next ranked band until a cap for the next ranked band is reached.
