Abstract: The present disclosure provides communication apparatus and communication method for channel estimation. The communication apparatus comprises a transmitter, which in operation, transmits a physical layer protocol data unit (PPDU) to one or more other communication apparatus in a multiple-input multiple-output (MIMO) wireless network, the PPDU including a long training field (LTF) that facilitates the one or more other communication apparatus to estimate respective channels for respective communications with the communication apparatus; and a controller, which in operation, establishes the number of LTF symbols (NLTF) for generating the LTF in the PPDU, wherein the NLTF depends on a maximum value (NSTSMAX) of the number of space-time streams for each resource unit (RU) in the PPDU.

Abstract: Se describe un método de transmisión que incluye: configurar un cuadro utilizando una pluralidad de símbolos de multiplexión por división de frecuencia ortogonal (OFDM), mediante la asignación de una pluralidad de datos de transmisión a una pluralidad de áreas; y transmitir el cuadro. La pluralidad de áreas son cada una identificadas por al menos un recurso de tiempo entre los recursos, y al menos un recurso de frecuencia entre los recursos de frecuencia. El cuadro incluye un primer período en el cual es transmitido un preámbulo, y un segundo período en el cual es transmitida la pluralidad de datos de transmisión por al menos uno de división de tiempo y división de frecuencia. El segundo período incluye una primera área, y la primera área incluye un símbolo de dato generado a partir del primer dato de transmisión, un símbolo de dato generado a partir del segundo dato de transmisión y subsecuente al símbolo de dato generado a partir del primer dato de transmisión, y un símbolo simulado subsecuente al símbolo de dato generado a partir del segundo dato de transmisión.

Abstract: The present disclosure provides communication apparatus and communication method for control signaling. The communication apparatus comprises: circuitry, which, in operation, generates a transmission signal comprising a first signal field and a second signal field, wherein the first signal field comprises punctured channel information and the second signal field comprises supplemental punctured channel information, wherein when the transmission signal is used for punctured single-user (SU) or multi-user (MU) multiple input multiple output (MIMO) transmission and the punctured channel information is able to indicate a channel puncturing pattern that is applied to the transmission signal, the second signal field does not comprise the supplemental punctured channel information; and a transmitter, which, in operation, transmits the transmission signal.
