Wireless communication method, user equipment and enode b

A wireless communication method performed by an eNB, comprising:

• receiving transport block repetitions transmitted from an UE, wherein
• one HARQ process comprises multiple repetition sets of a transport block if one repetition set of the transport block is not enough for the eNB to successfully decode the transport block,
• each of the multiple repetition sets comprises multiple repetitions of the transport block,
• the eNB indicates whether the transport block is successfully decoded by the eNB in a feedback channel by combining all received repetition sets of the transport block in current HARQ process after receiving each of the multiple repetition sets, and
• if the feedback channel indicates that the transport block is not successfully decoded by the eNB, the UE continues to transmit another repetition set of the transport block for the eNB to receive.

A wireless communication method performed by a UE, comprising:

• transmitting repetitions of a first message to an eNB for random access;
• and
• receiving a second message fed back from the eNB for indicating whether the first message is successfully decoded by the eNB, wherein
• if the second message indicates that the first message is not successfully decoded by the eNB, the transmitting and the receiving are repeated until the second message indicates that the first message is successfully decoded by the eNB, and
• the eNB combines all received repetitions of the first message from the UE to decode the first message.
