[srsran-users] ue earfcn selection possible bug

[J Giovatto]

Hi Folks,

I ran into an issue where I had multiple earfcn configured for the ue, 
but only the first was ever chosen in a hopeless cell search attempt.

Looks like a simple fix.

Before:

$ srsue ./ue.conf | grep index

02:02:34.394104 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:02:35.040149 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:02:36.040134 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:02:37.040093 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:02:38.040305 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:02:39.040181 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:02:40.040162 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:02:41.040105 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2

patch applied (see attached)

now with 2 earfcn

$ srsue ./ue.conf | grep index

02:04:40.382310 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:04:41.040164 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1,

index=0/2
02:04:43.040124 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=1/2
02:04:44.041107 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1,

02:04:45.041112 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1,

02:04:46.040130 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/2
02:04:47.040142 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=1/2


and with 3 earfcn

srsue ./ue.conf | grep index
02:05:44.385179 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/3
02:05:45.040103 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1,

index=2/3
02:05:53.040198 [PHY    ] [I] [    0] Cell Search: Start EARFCN -1, 
index=0/3
