Apparatus, system, and method for dynamic allocation using grant frames

摘要

Some illustrative embodiments include apparatuses, devices, systems, and methods for dynamically scheduling transmission opportunities. For example, the first wireless station generates a grant frame including a duration field and a dynamic allocation information field, where the dynamic allocation information field includes an allocation duration subfield, and the allocation duration subfield is When the grant frame grants the second radio station a period after the transmission opportunity (TxOP), the assigned duration subfield is set to a value within a predetermined value range, and the assigned duration subfield is set to the second radio station. When a period within the TxOP range is allowed, the frame may be set to a predetermined value that is not within the predetermined value range and transmit a permission frame during the TxOP.
