Device-to-reader transmission with midamble

An Internet of Things (IoT) device, comprising:

• a transceiver configured to receive a physical reader-to-device channel (PRDCH) from a reader, wherein the PRDCH provides information related to a physical device-to-reader channel (PDRCH) transmission including at least:
• a preamble format to prepend to the PDRCH between a short format and a long format,
• an interval for inserting one or more midambles in the PDRCH,
• an indicator for appending an additional midamble at an end of the PDRCH, and
• other device-to-reader (D2R) scheduling information;
• and
• processing circuitry operably coupled with the transceiver, the processing circuitry configured to determine, based on reception of the PRDCH, a transmission of the PDRCH to the reader including:
• the preamble format,
• whether to insert the one or more midambles, and
• whether to append the additional midamble,
• wherein the transceiver is further configured to transmit, based on the determination, the PDRCH with a preamble and the one or more midambles.

A reader, comprising:

• a processor;
• and
• a transceiver operably coupled with the processor, the transceiver configured to:
• transmit a physical reader-to-device channel (PRDCH) to an Internet of Things (IoT) device, wherein:
• the PRDCH provides information related to a physical device-to-reader channel (PDRCH) transmission including at least:
• a preamble format to prepend to the PDRCH between a short format and a long format,
• an interval for inserting one or more midambles in the PDRCH,
• an indicator for appending an additional midamble at an end of the PDRCH, and
• other device-to-reader (D2R) scheduling information, and
• transmission of the PRDCH indicates, for the PDRCH:
• the preamble format,
• whether to insert the one or more midambles, and
• whether to append the additional midamble;
• and
• receive the PDRCH with a preamble and the one or more midambles.
