Abstract
The present invention concerns a wireless device and a method at a wireless device for transmitting a packet, said method comprising the steps of setting a lifetime value to a packet to transmit and, while the packet lifetime has not expired and the packet transmission fails: retransmitting the packet up to a retry limit, and suspending transmitting said packet during a pause time before transmitting the packet up to a retry limit.
Claims10
A method for retransmitting a packet by a wireless device, said method comprising:
- setting a lifetime value to said packet;
- while the packet lifetime has not expired, retransmitting the packet using a first set of packet retransmissions until the retransmitting of the packet succeeds, wherein each of the packet retransmissions in the first set of the packet retransmissions is separated by a first pause period;
- and wherein if the packet has been retransmitted a number of retry limit times for the first set of the packet retransmissions,
- waiting for a second pause period before starting a next set of packet retransmissions, wherein each of the packet retransmissions in the next set of the packet retransmissions is also separated by the first pause period;
- and
- wherein rate of transmission is modified inside the first set of the retransmissions or between two sets of the retransmissions.
3 more elements
A wireless device for retransmitting a packet comprising:
- a wireless interface for communicating in a wireless network,
- a retransmission module for:
- setting a lifetime value to said packet;
- while the packet lifetime has not expired, retransmitting the packet using a first set of packet retransmissions until the retransmitting of the packet succeeds, wherein each of the packet retransmissions in the first set of the packet retransmissions is separated by a first pause period;
- and wherein if the packet has been retransmitted a number of retry limit times for the first set of the packet retransmissions, waiting for a second pause period before starting a next set of packet retransmissions, wherein each of the packet retransmissions in the next set of the packet retransmissions is also separated by the first pause period, said retransmission module in communication with said wireless interface;
- and
- wherein rate of transmission is modified inside the first set of the retransmissions or between two sets of the retransmissions.
4 more elements
A wireless device for retransmitting a packet, comprising:
- a wireless interface for communicating in a wireless network,
- a retransmission module for performing the retransmitting of the packet according to a first mode or a second mode, wherein;
- in the first mode the retransmission module sets a lifetime value for said packet, and while the packet lifetime has not expired, said retransmission module retransmits said packet until the retransmitting of the packet succeeds, and said retransmission module discards the packet if the packet has been retransmitted a number of retry limit times;
- in the second mode the retransmission module sets a lifetime value for said packet, and while the packet lifetime has not expired, said retransmission module retransmits the packet using a first set of packet retransmissions until the retransmitting of the packet succeeds, wherein each of the packet retransmissions in the first set of the packet retransmissions is separated by a first pause period;
- and wherein if the packet has been retransmitted a number of retry limit times for the first set of the packet retransmissions and if said packet retransmission has not been successful, said retransmission module waits for a second pause time before starting a next set of retransmissions, wherein each of the packet retransmissions in the next set of the packet retransmissions is also separated by the first pause period, said retransmission module in communication with said wireless interface;
- and
- wherein rate of transmission is modified inside the first set of the retransmissions or between two sets of the retransmissions.
