Abstract
A communication device communicates a radio frame including a preamble and a data field of a physical layer (PHY). The preamble includes an L-STF (Legacy Short Training Field), an L-LTF (Legacy Long Training Field), an L-SIG (Legacy Signal Field), an EHT-SIG-A (Extremely High Throughput Signal A Field), an EHT-STF, and an EHT-LTF, and the EHT-SIG-A includes a field indicating a standard that the radio frame complies with.
Claims27
A communication device, comprising:
- at least one memory that stores a set of instructions;
- and
- at least one processing circuit,
- wherein the communication device is caused, by the at least processing circuit executing the instructions and/or the at least processing circuit itself operating, to perform operations comprising:
- receiving a radio frame including a preamble and a data field of a physical layer (PHY);
- and
- decoding the radio frame,
- wherein the preamble includes a Legacy Short Training Field (L-STF), a Legacy Long Training Field (L-LTF), a Legacy Signal (L-SIG) field, a Repeated Legacy Signal (RL-SIG) field, an Extremely High Throughput (EHT) Short Training Field (EHT-STF), and an EHT Long Training Field (EHT-LTF),
- wherein another Signal field is placed between the RL-SIG and the EHT-STF in the preamble, and the another Signal field includes a first field in which a value indicating a version is stored, and
- wherein in a case where the value indicating the version is a value indicating an EHT, at least one field that composes the radio frame and that is received after reception of the another Signal Field is decoded, and in a case where the value indicating the version is not the value indicating the EHT, the field that composes the radio frame and that is received after reception of the another Signal Field is not decoded.
