A method of wireless communication, comprising: receiving a semi-persistent scheduling, SPS, message indicating transmission of a first TTI-bundled packet during a first period of a first hybrid automatic repeat request, HARQ, process, wherein each period of the first HARQ process comprises a subsequent second HARQ process 1; 1 See FIG. 8. 20ms SPS period 802 encompasses HARQ 0 and HARQ 1 even though HARQ 1 is not utilised in period 802. receiving a time division duplex, TDD, uplink/downlink, UL/DL, configuration for at least one TTI-bundled transmission; transmitting the first TTI-bundled packet on first resources during the first period of the first HARQ process, the first resources identified based on the TDD UL/DL configuration; identifying, based on the TDD UL/DL configuration, second resources for transmitting a second TTI-bundled packet in 2 a second period of the first HARQ process based on the SPS message; 2 Support from FIG. 8 determining whether to retransmit the first TTI-bundled packet; identifying, based on the TDD UL/DL configuration, retransmission resources for retransmitting the first TTI-bundled packet if it is determined that the first TTI-bundled packet is to be retransmitted, wherein the retransmission resources include the second resources for transmitting in the second period of the first HARQ process 3; and 3 See FIG. 8 "SPS (pkt 2) 814 determining to offset transmission of the second TTI-bundled packet to the subsequent second HARQ process in the second period of the first HARQ process 4 if at least one of the second resources for transmitting the second TTI-bundled packet overlaps with at least one of the retransmission resources used for retransmitting the first TTI-bundled packet. 4 Support from FIG. 8. HARQ offset from 814 to 816. receiving a semi-persistent scheduling, SPS, message indicating transmission of a first TTI-bundled packet during a first period of a first hybrid automatic repeat request, HARQ, process, wherein each period of the first HARQ process comprises a subsequent second HARQ process 1; 1 See FIG. 8. 20ms SPS period 802 encompasses HARQ 0 and HARQ 1 even though HARQ 1 is not utilised in period 802. receiving a time division duplex, TDD, uplink/downlink, UL/DL, configuration for at least one TTI-bundled transmission; transmitting the first TTI-bundled packet on first resources during the first period of the first HARQ process, the first resources identified based on the TDD UL/DL configuration; identifying, based on the TDD UL/DL configuration, second resources for transmitting a second TTI-bundled packet in 2 a second period of the first HARQ process based on the SPS message; 2 Support from FIG. 8 determining whether to retransmit the first TTI-bundled packet; identifying, based on the TDD UL/DL configuration, retransmission resources for retransmitting the first TTI-bundled packet if it is determined that the first TTI-bundled packet is to be retransmitted, wherein the retransmission resources include the second resources for transmitting in the second period of the first HARQ process 3; and 3 See FIG. 8 "SPS (pkt 2) 814 determining to offset transmission of the second TTI-bundled packet to the subsequent second HARQ process in the second period of the first HARQ process 4 if at least one of the second resources for transmitting the second TTI-bundled packet overlaps with at least one of the retransmission resources used for retransmitting the first TTI-bundled packet. 4 Support from FIG. 8.
