Claims

1. A terminal device comprising a receiving unit for receiving a trigger frame, wherein the trigger frame includes a User Info field, the User Info field includes a RU Allocation subfield, and a predetermined bit in the RU Allocation subfield is set to a predetermined value to indicate that the RU or MRU allocation is applied to a channel including a primary 80MHz channel or an NPCA primary channel.

2. The terminal device according to claim 1, wherein the predetermined bit is B0.

3. The terminal device according to claim 1, wherein the NPCA primary channel is a channel to which a user transitions from the primary channel when the primary channel is occupied by OBSS.

4. A base station device comprising a transmitting unit that transmits a trigger frame, wherein the trigger frame includes a User Info field, the User Info field includes a RU Allocation subfield, and a predetermined bit of the RU Allocation subfield is set to a predetermined value to indicate that the RU or MRU allocation is applied to a channel including a primary 80MHz channel or an NPCA primary channel.

5. The base station device according to claim 4, wherein the predetermined bit is B0.

6. The base station device according to claim 4, wherein the NPCA primary channel is a channel to which the primary channel is migrated when the primary channel is occupied by OBSS.

7. A communication method for a terminal device, comprising the step of receiving a trigger frame, wherein the trigger frame includes a User Info field, the User Info field includes a RU Allocation subfield, and a predetermined bit of the RU Allocation subfield is set to a predetermined value to indicate that the RU or MRU allocation is applied to a channel including a primary 80MHz channel or an NPCA primary channel.
