Abstract
A method for wireless communication, a transmitter, and a receiver are provided. The method includes the following. A transmitter transmits a first ultra-high reliability (UHR) extended long range (ELR) physical layer protocol data unit (PPDU). The first UHR ELR PPDU at least includes a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field, a universal signal (U-SIG) field, a UHR-STF, a UHR-LTF, a data field, and a packet extension (PE) field, where the data field is transmitted at a granularity of a first frequency-domain resource unit with N times duplication in a bandwidth of the first UHR ELR PPDU, and N equals to 4.

A method for wireless communication, comprising:
- transmitting, by a transmitter, a first ultra-high reliability (UHR) enhanced long range (ELR) physical layer protocol data unit (PPDU), wherein the first UHR ELR PPDU at least comprises a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field, a universal signal (U-SIG) field, a UHR-STF, a UHR-LTF, a data field, and a packet extension (PE) field, wherein the data field is transmitted at a granularity of a first frequency-domain resource unit with N times duplication in a bandwidth of the first UHR ELR PPDU, and N equals to 4;
- wherein a duration of the L-STF is 8 μs, a duration of the L-LTF is 8 μs, a duration of the L-SIG field is 4 μs, a duration of the RL-SIG field is 4 μs, a duration of the U-SIG field is 8 μs, and a duration of the UHR-STF is 4 μs;
- and
- wherein each of one or more of N−1 duplication transmissions of the data field has a phase rotation relative to a first transmission of the data field.
A transmitter, comprising:
- a transceiver;
- a processor coupled to the transceiver;
- and
- a memory storing a computer program which, when executed by the processor, causes the transmitter to:
- transmit a first ultra-high reliability (UHR) enhanced long range (ELR) physical layer protocol data unit (PPDU), wherein the first UHR ELR PPDU at least comprises a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field, a universal signal (U-SIG) field, a UHR-STF, a UHR-LTF, a data field, and a packet extension (PE) field, wherein the data field is transmitted at a granularity of a first frequency-domain resource unit with N times duplication in a bandwidth of the first UHR ELR PPDU, and N equals to 4;
- wherein a duration of the L-STF is 8 μs, a duration of the L-LTF is 8 μs, a duration of the L-SIG field is 4 μs, a duration of the RL-SIG field is 4 μs, a duration of the U-SIG field is 8 μs, and a duration of the UHR-STF is 4 μs;
- and
- wherein each of one or more of N−1 duplication transmissions of the data field has a phase rotation relative to a first transmission of the data field.
A receiver, comprising:
- a transceiver;
- a processor coupled to the transceiver;
- and
- a memory storing a computer program which, when executed by the processor, causes the receiver to:
- receive a first ultra-high reliability (UHR) enhanced long range (ELR) physical layer protocol data unit (PPDU), wherein the first UHR ELR PPDU at least comprises a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field, a universal signal (U-SIG) field, a UHR-STF, a UHR-LTF, a data field, and a packet extension (PE) field, wherein the data field is transmitted at a granularity of a first frequency-domain resource unit with N times duplication in a bandwidth of the first UHR ELR PPDU, and N equals to 4;
- wherein a duration of the L-STF is 8 μs, a duration of the L-LTF is 8 μs, a duration of the L-SIG field is 4 μs, a duration of the RL-SIG field is 4 μs, a duration of the U-SIG field is 8 μs, and a duration of the UHR-STF is 4 μs;
- and
- wherein each of one or more of N−1 duplication transmissions of the data field has a phase rotation relative to a first transmission of the data field.
