Abstract
Systems and techniques for traffic splitting based on latency between cells are herein described. At an eNodeB, a transmission path latency for a portion of a transmission path between the eNodeB and a user equipment (UE) may be measured via a secondary eNodeB when the UE is dually connected to both the eNodeB and the secondary eNodeB. The transmission path latency may be compared to a threshold. A layer in a transmission stack to split traffic to the UE may be determined based on the comparison of the transmission path latency to the threshold, the traffic being split between the eNodeB and the secondary eNodeB.
Claims21
An eNodeB for traffic splitting based on latency between cells, the eNodeB comprising:
- a latency testing module to measure a transmission path latency for a portion of a transmission path between the eNodeB and a user equipment (UE) via a secondary eNodeB when the UE is dually connected to both the eNodeB and the secondary eNodeB;
- a latency calculation module to compare the transmission path latency to a threshold, wherein to compare the transmission path latency to the threshold includes a determination that the transmission path latency is greater than the threshold;
- and
- a traffic splitting module to determine a layer in a transmission stack to split traffic to the UE based on the comparison of the transmission path latency to the threshold, the traffic being split between the eNodeB and the secondary eNodeB, wherein the layer of the transmission stack is either a packet data convergence protocol (PDCP) layer or a radio link control (RLC) layer, and wherein to determine the layer in the transmission stack includes a selection of the PDCP layer.
A method performed by an eNodeB for traffic splitting based on latency between cells, the method comprising:
- measuring a transmission path latency for a portion of a transmission path between the eNodeB and a user equipment (UE) via a secondary eNodeB when the UE is dually connected to both the eNodeB and the secondary eNodeB;
- comparing the transmission path latency to a threshold, wherein comparing the transmission path latency to the threshold includes determining that the transmission path latency is greater than the threshold;
- and
- determining a layer in a transmission stack to split traffic to the UE based on the comparison of the transmission path latency to the threshold, the traffic being split between the eNodeB and the secondary eNodeB, wherein the layer of the transmission stack is either a packet data convergence protocol (PDCP) layer or a radio link control (RLC) layer, and wherein determining the layer in the transmission stack includes selecting the PDCP layer.
At least one non-transitory machine readable medium including instructions that, when executed by an eNodeB, cause the eNodeB to perform operations for traffic splitting based on latency between cells, the operations comprising:
- measuring a transmission path latency for a portion of a transmission path between the eNodeB and a user equipment (UE) via a secondary eNodeB when the UE is dually connected to both the eNodeB and the secondary eNodeB;
- comparing the transmission path latency to a threshold, wherein comparing the transmission path latency to the threshold includes determining that the transmission path latency is greater than the threshold;
- and
- determining a layer in a transmission stack to split traffic to the UE based on the comparison of the transmission path latency to the threshold, the traffic being split between the eNodeB and the secondary eNodeB, wherein the layer of the transmission stack is either a packet data convergence protocol (PDCP) layer or a radio link control (RLC) layer, and wherein determining the layer in the transmission stack includes selecting the PDCP layer.
