1. An apparatus for transmitting a bit in addition to a plurality of payload data symbols of a communication protocol, the apparatus comprising:
an input interface configured to receive information about a bit value of the bit; and
a transmission circuit configured to:
if the bit value is a first value, transmit the plurality of payload data symbols at predetermined positions in a data signal as pulses of variable pulse length, wherein a respective pulse length of each of the pulses of variable pulse length is selected based on a symbol value of the payload data symbol represented by each pulse of variable pulse length; and
if the bit value is a second value, transmit a pulse exhibiting an extended pulse length being longer than a maximum payload data symbol pulse length defined in the communication protocol at the predetermined position of the pulse for a d-th payload data symbol of the plurality of payload data symbols, wherein d=k+i if k+i≤z, wherein d=([k+i] mod z) if k+i>z, wherein k is the symbol value of a i-th payload data symbol of the plurality of payload data symbols, wherein z is the number of possible symbol values of the payload data symbols defined in the communication protocol, and wherein 1≤i≤z.
