1. A transmitter comprising
at least one processor; and
at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the transmitter at least to perform:
sensing whether a channel is busy or idle;
setting a counter to a starting value;
updating the counter value during sensing;
determining, in response to there being data to be transmitted, based on at least the counter value at one of a plurality of defined transmit opportunities and a duration for which the channel has been sensed idle before the one transmit opportunity, whether to transmit the data or to continue the sensing of the channel to a next transmit opportunity without resetting the counter value to the starting value; and
repeating the determining until the data is transmitted.
