Abstract

Embodiments of this application relate to the field of wireless communication technologies, and disclose a communication method and apparatus. The method includes: generating a PPDU, where the PPDU has one or more discrete resource units, the discrete resource unit includes a plurality of sub-resource units, the plurality of sub-resource units include a plurality of discontiguous sub-resource units in an unpunctured sub-channel in a first channel, and/or the plurality of sub-resource units include a plurality of sub-resource units in a plurality of unpunctured sub-channels in the first channel; the sub-channel includes a plurality of resource units RUs, and the sub-resource unit includes some or all subcarriers in one RU; and the first channel includes a plurality of sub-channels; and sending the PPDU. The solutions in this application are used in a wireless local area network system supporting a next-generation Wi-Fi EHT protocol of the IEEE 802.11.

Dependent claims

A communication method, wherein the method comprises:

generating a physical layer protocol data unit (PPDU), wherein the PPDU has a plurality of discrete resource units (RUs) in a plurality of sub-channels of a first channel arranged in sub-channel combinations, wherein at least one of the sub-channels in the sub-channel combinations is punctured, at least a first sub-channel combination having one punctured sub-channel and at least a second sub-channel combination having no punctured sub-channels,
the plurality of discrete resource units include a plurality of discontinuous discrete resource units in an unpunctured sub-channel in the first sub-channel combination in the first channel by performing single sub-channel RU spreading (SS-RU) on the unpunctured channel, and the plurality of discrete resource units include discrete resource units in a plurality of unpunctured sub-channels in the second sub-channel combination in the first channel;
and
sending the PPDU.

1 more element
