A method, comprising:
- performing, by a user equipment, listen before talk (LBT);
- in response to the listen before talk (LBT) being successful, transmitting an intended transmission subsequent to the listen before talk (LBT);
- in response to the listen before talk (LBT) not being successful, transmitting an indication of listen before talk (LBT) failure by transmitting a portion of the intended transmission subsequent to the listen before talk (LBT).
An apparatus, comprising:
- at least one processor;
- and
- at least one memory comprising computer program code,
- the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to perform:
- performing listen before talk (LBT);
- in response to the listen before talk (LBT) being successful, transmitting an intended transmission subsequent to the listen before talk (LBT);
