Long range wide area network (LoRaWAN) attracts attention due to its ability to realize massive machine-type communication (MTC); however, its throughput is limited by the duty cycle (DC). Packet-level index modulation (PLIM) increases the throughput by utilizing a data packet's frequency channel and transmission timing as an information-bearing index. In PLIM, a node transmits a packet at a specific transmission resource (frequency channel and timing) within a frame, and the node discards the packet if it cannot transmit the packet at the specific transmission resource. This paper proposes an index mapping scheme that divides a frame into multiple subframes and performs channel activity detection (CAD) in each subframe. Computer simulations show that the proposed scheme improves the throughput by increasing the transmission opportunities and reducing the packet discard under the constraint of DC. |
