1. An electronic device for a transmitter, comprising:
a processing circuitry configured to:
perform an initial transmission of a transport block followed by a predetermined first number of blind transmissions of the transport block to a receiver by a configured Hybrid Automatic Repeat reQuest (HARQ) process, the predetermined first number of blind transmissions scheduled to be performed within a predetermined time window that starts upon completion of the initial transmission of the transport block, the predetermined first number having been notified to the receiver;
perform detection for a HARQ feedback from the receiver within a second predetermined time window that starts upon completion of the initial transmission of the transport block and that has an end time that is later than an end time of the predetermined time window, the HARQ feedback indicating whether decoding for the transport block at the receiver is successful or not;
at least one of:
a) based on the HARO feedback being detected within the second predetermined time window and indicating unsuccessful decoding by the receiver:
perform control to continue any of the predetermined first number of blind transmissions that have not yet been performed within the predetermined time window. and
based on the HARQ feedback not being detected after the predetermined time window and within the second predetermined time window, perform a HARQ retransmission of the transport block followed by a predetermined second number of blind transmissions of the transport block, the predetermined second number of blind transmissions scheduled to be performed within a third predetermined time window that starts upon completion of the HARQ retransmission of the transport block, the predetermined second number having been notified to the receiver, or
b) based on the HARQ feedback not being detected within the second predetermined time window;
perform the HARQ retransmission of the transport block followed by the predetermined second number of blind transmissions of the transport block, the predetermined second number of blind transmissions scheduled to be performed within the third predetermined time window that starts upon completion of the HARQ retransmission of the transport block, the predetermined second number having been notified to the receiver;
perform a second detection for the HARQ feedback from the receiver within a fourth predetermined time window that starts upon completion of the HARQ retransmission of the transport block and that has an end time that is later than an end time of the third predetermined time window, the HARQ feedback indicating whether decoding for the HARQ retransmission of the transport block at the receiver is successful or not; and
based on the HARQ feedback being detected within the fourth predetermined time window and indicating successful decoding by the receiver, perform control to cancel any of the predetermined second number of blind transmissions that have not yet been performed within the third predetermined time window.
