anglais vers français Technique / Génie Brevets (in a patent) HE-SIG-B COMMON FIELD FORMATS AND ALLOCATION

the operation bandwidth is 160 MHz, and wherein the middle RU indicator for middle 26 tone RU of lower 80 MHz is included in common field of HE SIG B channel 1 and the middle RU indicator for middle 26 tone RU of upper 80MHz is included in common field of HE SIG B channel 2.

the operation bandwidth is 160 MHz, and wherein the user specific field for middle 26 tone RU of lower 80Mhz is placed at an end of HE-SIG-B channel 1 and the user specific field of middle 26 tone RU of upper 80 MHz is placed at an end of HE-SIG-B channel 2.

A middle RU handling circuit 196 détermines the existence of user spécifie field for middle 26 tone RU of a 80Mhz channel.

The 80 MHz can be partitioned in four sets of nine 26-tone resource units with two 26-tone mid-tone RUs, four sets of five 52-tone resource units with two 26-tone mid-tone RUs, four sets of 106-tone resource units, two sets of 26-tone mid-tone unit, two sets of two 242-tone units with two 26-tone mid-tone RUs, two 484-tone resource unit with two 26-tone mid-tone RUs, and a 996-tone resource unit.

two user spécifie fields for middle RU of lower and upper 80MHz when opération bandwidth is 160MHz as shown in 620. In yet another embodiment, as shown in 630, two unused indices in the RA LUT are used to indicate whether the middle 26 tone RU for 80Mhz is assigned.
