Abstract
First data packets for a wireless device are received at a network element and are encoded into at least one second data packet, the second data packet comprising at least two of the first data packets. The at least one second data packet is sent from the network element to the wireless device. A round trip time related to the at least one second data packet, and a frequency band load of a frequency band to deliver the at least one second data packet to the wireless device are determined. A number of permitted retransmissions of the at least one second data packet from the access node to the wireless device is adjusted based on the round trip time and the frequency band load.
Claims11
A method of managing data retransmission to a wireless device, comprising:
- receiving at a network element first data packets for the wireless device and encoding the first data packets into at least one second data packet, the second data packet comprising at least two of the first data packets, and sending the at least one second data packet from the network element to the wireless device;
- determining a round trip time related to the at least one second data packet;
- determining a frequency band load of a frequency band between an access node and the wireless device to deliver the at least one second data packet to the wireless device;
- determining a modulation and coding scheme assigned to a communication link between the access node and the wireless device;
- and
- adjusting a number of permitted retransmissions of the at least one second data packet from the access node to the wireless device based on the round trip time, the frequency band load, and the modulation and coding scheme.
A system of managing data retransmission to a wireless device, comprising:
- a processing node, further configured to:
- receive at a network element first data packets for the wireless device and encoding the first data packets into at least one second data packet, the second data packet comprising at least two of the first data packets, and sending the at least one second data packet from the network element to the wireless device;
- determine a round trip time related to the at least one second data packet;
- determine a frequency band load of a frequency band between an access node and the wireless device to deliver the at least one second data packet to the wireless device;
- determine an application requirement of an application running on the wireless device, wherein the at least one second data packet is sent to the application;
- and
- adjust a number of permitted retransmissions of the at least one second data packet from the access node to the wireless device based on the round trip time, the frequency band load, and the application requirement.
A method of managing data retransmission to a wireless device, comprising:
- receiving at a network element first data packets for the wireless device and encoding the first data packets into at least one second data packet, the second data packet comprising at least two of the first data packets, and sending the at least one second data packet from the network element to the wireless device;
- determining a round trip time related to the at least one second data packet;
- determining a frequency band load of a frequency band between an access node and the wireless device to deliver the at least one second data packet to the wireless device;
- determining a retransmission overhead associated with a retransmission of the at least one second data packet from the access node to the wireless device;
- adjusting a number of permitted retransmissions of the at least one second data packet from the access node to the wireless device based on the round trip time, the retransmission overhead, and the frequency band load;
- and
- resending the at least one second data packet from the network element to the wireless device when a number of retransmissions of the at least one second data packet from the access node to the wireless device meets the adjusted number of permitted retransmissions of the at least one second data packet.
