Does BLE retransmission happen in same connection interval?

Hi All

I am now developing BLE application on nRF52840 DK. I have a question about BLE retransmission process.

When master sends a packet to initiate a connection event/interval, but due to interference, slave cannot receive it. Thus, there will not be a packet back to master from slave. Does master retransmit that packet in this connection event/interval or next one? If master retransmit that packet in the same connection interval, when will it do it?

Thanks in advance.
