Abstract
A multicast packet transmitting method of wireless network is provided. According to the method, a first transmitting terminal adds a first acknowledge serial number into a multicast downlink packet and transmits the downlink packet to a second transmitting terminal. After transmitting the downlink packet, the first transmitting terminal determines whether to re-transmit the downlink packet in accordance to a received second acknowledge serial number in an uplink packet, which is output from the second transmitting terminal.
Claims19
A packet transmission method of wireless network, comprising:
- adding a first acknowledge serial number into a downlink packet by a first transmitting terminal;
- sending the downlink packet including the first acknowledge serial number to a second transmitting terminal by the first transmitting terminal;
- and
- determining whether to re-transmit the downlink packet by the first transmitting terminal according to a second acknowledge serial number in an uplink packet received from the second transmitting terminal after the first transmitting terminal outputs the downlink packet, wherein a packet serial number of the uplink packet received previously is used as the first acknowledge serial number every time before transmitting the downlink packet.
A packet transmission method of wireless network, comprising:
- adding a first acknowledge serial number into a downlink packet by a first transmitting terminal;
- sending the downlink packet including the first acknowledge serial number to a second transmitting terminal by the first transmitting terminal;
- determining whether to re-transmit the downlink packet by the first transmitting terminal according to a second acknowledge serial number in an uplink packet received from the second transmitting terminal after the first transmitting terminal outputs the downlink packet;
- providing a collision count in the downlink packet when transmitting the downlink packet by the first transmitting terminal;
- and
- determining a backoff time of the subsequent uplink packet according to the collision count by the second transmitting terminal,
- wherein the collision count is stored in a fragment number of the MAC header of the downlink packet.
