Abstract
A communication apparatus of the present disclosure includes a receiver which, in operation, receives a signal that includes a non-legacy preamble and a data field, the non-legacy preamble comprising a first field for indicating a number of spatial streams (Nss) in the data field and a second field for indicating one of a plurality of modulation and coding schemes (MCSs), wherein two or more frequency diversity transmission schemes are supported and one of the two or more frequency diversity transmission schemes is applied based on a value of the Nss; and circuitry which, in operation, decodes the signal.
Claims14
An integrated circuit for a communication apparatus, the integrated circuit comprising,
- at least one input, which, in operation, inputs an electronic signal, and
- control circuitry, which, in operation, controls:
- receiving a transmission signal wherein at least a part of the transmission signal is transmitted using one or more spatial streams;
- and
- decoding the transmission signal,
- wherein reception of transmission signals transmitted by two or more frequency diversity transmission schemes is supported, and
- one of the two or more frequency diversity transmission schemes is applied to the transmission signal based on a number of the spatial streams.
An integrated circuit for a communication apparatus, the integrated circuit comprising,
- at least one output, which, in operation, outputs an electronic signal, and
- control circuitry, which, in operation, controls:
- generating a transmission signal wherein at least a part of the transmission signal is transmitted using one or more spatial streams;
- and
- transmitting the transmission signal,
- wherein transmission of transmission signals transmitted by two or more frequency diversity transmission schemes is supported, and
- one of the two or more frequency diversity transmission schemes is applied to the transmission signal based on a number of the spatial streams.
