NRT mechanisms are not sufficient to guarantee seamless co-running of LTE and 
connectivity systems (WLAN, BT, and GNSS). 
 

Inter-system Synchronization 
 

For the cases where co-running of LTE and connectivity systems cannot be achieved, a Real 
Time (RT) coexistence controller is implemented in the LTE Layer-1 subsystem. The RT 
coexistence controller is in control of the RT coexistence interface, which is exposed to the 
connectivity chip. The RT coexistence controller exploits real time information received from 
the LTE Layer-1 subsystem and from the connectivity chip to coordinate LTE and 
connectivity “in the air” activities. The coordination function protects LTE traffic while 
optimizing the throughput and availability of WLAN/BT/GNSS. When operating in this mode, 
the connectivity systems have reduced capability since they access the medium when LTE is 
inactive, or when their respective operations do not impact each other significantly. 
 
The Non Real-Time mechanism implements a messaging based interface, formatted as AT 
commands that are passed to the AP host over the IPC interface (USB). A simple piece of SW 
residing on the AP host will tunnel the Non Real-Time messages between the BT/WLAN 
device and M.2 module, translate AT commands to/from the BT/WLAN driver commands, 
and maintain the states of the BT/ WLAN and M.2 LTE modem. The host software will also 
be responsible for initializing the Real-Time mechanism. 

 

 

The Real-Time mechanism consists of 3 GPIO signals which allow the synchronization of 
multiple TX and RX events. The signals to support real Time coexistence are listed in 

 

Table 

18. 

 

If the coexistence signals are not used by the host system, they should not be 
connected.
