Abstract
Systems, methods and processing nodes are provided for prioritization of relay data packets. A processor determines one or more of a buffer status for the relay node and a load within the sector, compares the buffer status and/or the load to threshold values, and applies an updated QoS profile to the relay node when the comparisons satisfy particular criteria.
Claims19
A method comprising:
- identifying, in a network utilizing a first radio access technology (RAT) and a second higher performance RAT, a relay node as utilizing the second higher performance RAT;
- receiving a buffer status report from the relay node utilizing the second higher performance RAT;
- determining if a relay node buffer for the relay node utilizing the second higher performance RAT is full based on the buffer status report;
- and
- applying an updated quality of service (QoS) profile to the relay node when the relay node buffer is full, thereby improving QoS for the relay node utilizing the second higher performance RAT.

A system comprising:
- a master node communicating using a first radio access technology (RAT) and at least one secondary node utilizing a second higher performance RAT, the master node and the secondary node connected by a link and communicating with multiple wireless devices within a sector;
- at least one relay node communicating with the master node and the secondary node;
- and
- at least one processor configured to:
- identify the relay node as utilizing the second higher performance RAT;
- determine a load within the sector;
- compare the load to a threshold load value;
- and
- apply an updated QoS profile to the relay node utilizing the second higher performance RAT when the load satisfies the threshold load value in order to prioritize data packets from the relay node utilizing the second higher performance RAT over data packets from other relay nodes.

A processing node configured to perform operations comprising:
- a processor executing instructions to perform operations including,
- determining a load on a sector by determining an end-to-end latency on a link between a master node utilizing a first radio access technology (RAT) and secondary node using a second higher performance RAT communicating with a relay node utilizing the second higher performance RAT;
- comparing the load to a threshold load value;
- receiving a buffer status report from the relay node utilizing the second higher performance RAT;
- comparing the buffer status to a predetermined threshold;
- and
- applying an updated QoS profile to a relay node utilizing the second higher performance RAT within the sector when the load satisfies the threshold load value and the buffer status satisfies the predetermined threshold.
