Systems, apparatuses, methods, and non-transitory computer-readable storage devices for wireless communication employing mixed distributive resource units and regular resource units

A communication method, comprising:

• receiving a first signal of an orthogonal frequency-division multiple access (OFDMA) physical layer protocol data unit (PPDU);
• and
• transmitting a second signal to a device using a resource unit (RU) in the OFDMA PPDU, the RU comprising a plurality of subcarriers;
• wherein the RU is one of a plurality of RUs of the OFDMA PPDU;
• wherein the RU belongs to either a first set including at least one first RU or a second set including at least one second RU;
• wherein if the RU belongs to the first set, the plurality of subcarriers of the RU are same subcarriers determined in accordance with a design method that distributes the subcarriers, and if the RU belongs to the second set, the plurality of subcarriers of the RU are arranged consecutively;
• and
• wherein the first signal comprises resource allocation information of the plurality of RUs in the OFDMA PPDU;
• and wherein the plurality of subcarriers of the RU in the OFDMA PPDU are determined using the resource allocation information of the plurality of RUs in the OFDMA PPDU.

A communication method, comprising:

• transmitting a first signal of an orthogonal frequency-division multiple access (OFDMA) physical layer protocol data unit (PPDU);
• wherein the OFDMA PPDU comprises a plurality of RUs, the plurality of RUs comprises a first set including at least one first RU and a second set including at least one second RU, each first RU of the first set comprises a plurality of first subcarriers for data and/or pilot-symbol transmission, and each second RU of the second set comprises a plurality of second subcarriers for data and/or pilot-symbol transmission;
• and
• wherein the plurality of first subcarriers of each first RU of the first set are same subcarriers determined in accordance with a design method that distributes the first subcarriers, and the plurality of second subcarriers of each second RU of the second set are arranged consecutively;
• and
• wherein the first signal comprises resource allocation information of the plurality of RUs in the OFDMA PPDU, and the resource allocation information is used to determine parameters used in the design method that distributes the first subcarriers.
