Abstract
The present invention improves channel estimation accuracy in wireless communication. This communication device comprises: a control circuit that sets, to a control signal, information relating to an additional reference signal for each destination device; and a transmission circuit that transmits the control signal.
Claims9
A communication apparatus, comprising:
- control circuitry, which, in operation, sets, to an extremely high throughput physical layer convergence procedure protocol data unit (EHT PPDU), information on an extra reference signal for each destination apparatus;
- and
- transmission circuitry, which, in operation, transmits the EHT PPDU,
- wherein,
- the information is included in a common field of an EHT signal (EHT-SIG) as an extra subfield of a universal signal (U-SIG), and
- the control circuitry sets a number of EHT long training fields (EHT-LTFs) in the EHT PPDU greater than a number of EHT-LTFs specified based on a number of spatial streams.

A communication method, comprising:
- configuring, by a communication apparatus, to an extremely high throughput physical layer convergence procedure protocol data unit (EHT PPDU), information on an extra reference signal for each destination apparatus;
- and
- transmitting, by the communication apparatus, the EHT PPDU,
- wherein,
- the information is included in a common field of an EHT signal (EHT-SIG) as an extra subfield of a universal signal (U-SIG), and
