1. A communication apparatus, comprising:
circuitry which, in operation, generates a transmission signal that includes a data field, the data field carrying an aggregated medium access control protocol data unit (A-MPDU) that is segmented into one or more code blocks; and
a transmitter which, in operation, transmits the transmission signal to another communication apparatus, wherein,
the A-MPDU comprises one or more A-MPDU subframes that are mapped to the one or more code blocks, such that a first A-MPDU subframe not soliciting immediate acknowledgement and a second A-MPDU subframe soliciting immediate acknowledgement are not mapped into a single code block,
in response to a first code block in which the first A-MPDU subframe does not solicit immediate acknowledgement, the first code block is mapped to align with a boundary of the first A-MPDU subframe, and
in response to a second code block in which the second A-MPDU subframe solicits immediate acknowledgement, the second code block is mapped to align with a boundary of the second A-MPDU subframe.
