Unicast Aggregation With Minimal Pipeline Flushing in Wireless Communication Networks
Summary
USPTO published patent application US20260100919A1 disclosing methods for unicast packet aggregation in time-slotted multi-hop wireless networks. The invention enables a source node to aggregate unicast packets destined for multiple destinations with the same priority into a single MAC Protocol Data Unit, reducing contention for channel access. The application also describes minimal pipeline flushing techniques allowing earlier scheduling of source nodes.
What changed
USPTO published patent application US20260100919A1 for methods and systems improving network performance in time-slotted multi-hop wireless networks, specifically a Barrage Relay network. The invention aggregates unicast packets across multiple destinations with the same priority into one MAC Protocol Data Unit, enabling a single request message to a network controller for multiple unicast packets. The application also covers minimal pipeline flushing allowing source nodes to be scheduled sooner than required to fully flush the spatial pipeline.
For technology companies and network equipment manufacturers, this patent application indicates potential future intellectual property claims in wireless communication optimization. Entities developing multi-hop wireless networks or network controllers should monitor the prosecution of this application to understand the scope of any claims that may issue.

UNICAST AGGREGATION WITH MINIMAL PIPELINE FLUSHING IN WIRELESS COMMUNICATION NETWORKS

Abstract
Methods and systems that improve network performance in time-slotted multi-hop wireless networks, e.g., a Barrage Relay network, are described. In an aspect, the broadcast nature of the Barrage Relay network is leveraged to enable a source node to aggregates unicast packets across multiple destinations with the same priority in one Medium Access Control (MAC) Protocol Data Unit (MPDU). This aggregation advantageously enables a single request message to be sent to a network controller for multiple unicast packets destined for multiple destinations, thereby reducing the contention channel access significantly. In addition, minimal pipeline flushing allows the source node to be scheduled sooner than is required to fully flush the spatial pipeline. This advantageously enables scheduling of queued source nodes to minimize the sum switching delay.
