    摘要: A fast retransmission method by introducing the internal node under better channel condition to join the work of retransmission after the destination node sends out the packet loss indication for unicast services. Extended to serve multicast services, a system comprising a plurality of nodes utilizes the farthest node in each branch from the source to transmit an acknowledge signal when packet loss occurs. The system then enables the closest node to the acknowledging node to retransmit the requested packet, thereby improving the target packet hit rate and data integrity with less retransmission steps.

    摘要: It is provided a method for determining channel quality for a second channel, wherein, the second channel is overlapping with a first channel, the method comprising the steps of sending a request message through the first channel; receiving a response message on the second channel in response to the request message through the first channel; and determining the channel quality of the second channel based on the response message on the second channel. It can be used to determine the channel quality of at least one channel by sending a single message through the first channel.
