A method of wireless communication at a first node, comprising: determining a plurality of frames including a first frame and a second frame based on synchronization information, wherein the plurality of frames each have a plurality of data slots and a plurality of element periods, each of the plurality of element periods corresponding to a respective slot of the plurality of data slots, wherein: the plurality of data slots include a first data slot; and a first reservation resource and a second reservation resource are in a first element period of the first frame, the first element period corresponding to the first data slot of the first frame; determining to transmit a first packet to a second node in the first data slot of the first frame, the first data slot of the first frame being associated with the first reservation resource and the second reservation resource; determining whether the first node transmitted a second packet of priority-based traffic in a first data slot of the second frame, wherein the second frame is prior to the first frame; and determining whether the first node has a privilege for the first data slot of the first frame, when the first packet is of the priority-based traffic, wherein when the first node transmitted the second packet of the priority-based traffic in the first data slot of the second frame, characterized in that the first node is determined to have the privilege for the first data slot of the first frame in response to a determination that the first node transmitted the second packet in the first data slot of the second frame, and the method further comprises: transmitting a first reservation message to the second node in the first reservation resource of the first element period of the first frame; receiving a second reservation message from the second node in the first reservation resource of the first element period of the first frame; and transmitting the first packet to the second node in the first data slot of the first frame. determining a plurality of frames including a first frame and a second frame based on synchronization information, wherein the plurality of frames each have a plurality of data slots and a plurality of element periods, each of the plurality of element periods corresponding to a respective slot of the plurality of data slots, wherein: the plurality of data slots include a first data slot; and a first reservation resource and a second reservation resource are in a first element period of the first frame, the first element period corresponding to the first data slot of the first frame; the plurality of data slots include a first data slot; and a first reservation resource and a second reservation resource are in a first element period of the first frame, the first element period corresponding to the first data slot of the first frame; determining to transmit a first packet to a second node in the first data slot of the first frame, the first data slot of the first frame being associated with the first reservation resource and the second reservation resource; determining whether the first node transmitted a second packet of priority-based traffic in a first data slot of the second frame, wherein the second frame is prior to the first frame; and determining whether the first node has a privilege for the first data slot of the first frame, when the first packet is of the priority-based traffic, wherein when the first node transmitted the second packet of the priority-based traffic in the first data slot of the second frame, characterized in that the first node is determined to have the privilege for the first data slot of the first frame in response to a determination that the first node transmitted the second packet in the first data slot of the second frame, and the method further comprises: transmitting a first reservation message to the second node in the first reservation resource of the first element period of the first frame; receiving a second reservation message from the second node in the first reservation resource of the first element period of the first frame; and transmitting the first packet to the second node in the first data slot of the first frame. transmitting a first reservation message to the second node in the first reservation resource of the first element period of the first frame; receiving a second reservation message from the second node in the first reservation resource of the first element period of the first frame; and transmitting the first packet to the second node in the first data slot of the first frame.
