Abstract

See full text

Provided is a communication apparatus and communication method for channel estimation. The communication apparatus includes 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 includes a long training field (LTF) that permits the one or more other communication apparatus to estimate respective channels for respective communications with the communication apparatus. The communication apparatus includes a controller, which in operation, establishes the number of LTF symbols (NLTF) for generating the LTF in the PPDU. The NLTF depends on a maximum value (NSTSMAX) of the number of space-time streams for each resource unit (RU) in the PPDU.
