Wireless communication device and wireless communication method

An electronic apparatus comprising:

• reception circuitry configured to;
• receive a first beacon frame including first information indicative at least one node to be reassigned a slot and a slot reassignment,
• wherein a beacon interval of the base station includes a scheduled access period, a control and management period arranged after the scheduled access period and an inactive period arranged after the control and management period,
• wherein the scheduled access period is used for communication according to an allocated slot,
• wherein the control and management period is used for communication of a signal for control or management and
• wherein the inactive period is not used for communication,
• receive a management frame including second information indicative the reassigned slot within a first control and management period included in a first beacon interval between the first beacon frame and a second beacon frame, and
• receive the second beacon frame, and
• transmission circuitry configured to transmit a first data frame including a bit for acknowledgement of reception of the management frame in a header within a second beacon interval between the second beacon frame and a third beacon frame if the reception circuitry successfully receives the management frame.

A wireless communication method at least partially performed by an electronic apparatus, comprising:

• transmitting a first beacon frame including first information indicative at least one terminal to be reassigned a slot and a slot reassignment timing,
• wherein a beacon interval includes a scheduled access period, a control and management period arranged after the scheduled access period and an inactive period arranged after the control and management period,
• wherein the scheduled access period is used for communication according to an allocated slot,
• wherein the control and management period is used for communication of a signal for control or management and
• wherein the inactive period is not used for communication;
• transmitting a management frame including second information indicative the reassigned slot within a first control and management period included in a first beacon interval between the first beacon frame and a second beacon frame;
• transmitting the second beacon frame;
• and
• receiving a first data frame including a bit for acknowledgement of reception of the management frame in a header within a second beacon interval between the second beacon frame and a third beacon frame if the management frame is successfully received.
