Wireless communication method and wireless communication device for enhanced multi-resource unit puncturing pattern transmission

A wireless communication method for receiving a physical layer protocol data unit (PPDU), the wireless communication method comprising:

• receiving, by a wireless communication device, the PPDU from a transmitting device, wherein the PPDU is transmitted over a channel bandwidth comprising a plurality of subchannels;
• extracting signaling information from a preamble of the PPDU;
• determining, based on the signaling information, that an enhanced multi-resource unit (MRU) puncturing pattern is used for the PPDU;
• identifying the enhanced MRU puncturing pattern based on the signaling information;
• and
• decoding payload data from the PPDU based on the identified enhanced MRU puncturing pattern.

A wireless communication device, the wireless communication device comprising:

• a transceiver configured to transmit and receive physical layer protocol data units (PPDUs) over a wireless channel;
• and
• a processor coupled to the transceiver, the processor configured to:
• determine an enhanced multi-resource unit (MRU) puncturing pattern for transmission, wherein the enhanced MRU puncturing pattern indicates at least one of:
• for a channel bandwidth of 80 MHz or 160 MHz, at least two punctured subchannels;
• or
• for a channel bandwidth greater than or equal to 320 MHz, at least one of:
• exactly one punctured subchannel having a bandwidth of 20 MHz;
• at least two punctured subchannels having a same bandwidth;
• exactly two punctured subchannels having different bandwidths, wherein one of the exactly two punctured subchannels has a bandwidth of 20 MHz;
• exactly two punctured subchannels having bandwidths of 40 MHz and 80 MHz, wherein the 80 MHz punctured subchannel is not located at either a lowest frequency end or a highest frequency end of the channel bandwidth;
• or
• at least three punctured subchannels;
• generate a preamble for inclusion in a PPDU, the preamble including signaling information configured to indicate that the enhanced MRU puncturing pattern is used and to identify the enhanced MRU puncturing pattern;
• and
• control the transceiver to transmit the PPDU including the preamble.
