Engineering Contradiction Analysis
1Ease of operation
If network nodes perform independent beamforming procedures without coordination, then each node can operate autonomously with simple local decision-making, but interference increases and communication efficiency decreases in heterogeneous networks
Solution Approach 1:
The patent introduces a coordination mechanism where network nodes exchange beam sequence indications through signaling protocols. This intermediary communication channel allows nodes to coordinate their beamforming operations, reducing interference while maintaining operational autonomy. The signaling acts as a mediator that enables cooperative behavior without requiring direct control or complex centralized management.
2Productivity
If network nodes implement coordinated beamforming with beam sequence exchange, then interference is reduced and communication efficiency improves, but system complexity increases due to additional signaling and coordination protocols
Solution Approach 1:
The patent implements preliminary action by having network nodes exchange beam sequence indications before actually performing beamforming operations. This advance coordination allows nodes to select beam sequences that minimize interference from the outset, rather than needing complex real-time adjustment mechanisms. The preliminary exchange of beam information simplifies the overall system by preventing interference proactively.
Solution Approach 2:
The coordination mechanism incorporates feedback through the exchange of beam sequence indications between network nodes. Each node provides information about its selected beam sequences to neighboring nodes, which then use this feedback to adjust their own beamforming choices. This feedback loop enables adaptive coordination that improves communication efficiency while keeping the complexity manageable through standardized signaling protocols.
3Speed
If beam sequence selections are made independently by each network node, then decision-making is fast and simple, but suboptimal performance results due to lack of coordination in heterogeneous network environments
Solution Approach 1:
The patent maintains fast beam selection by implementing preliminary exchange of beam sequence indications before the actual beamforming operation. This advance coordination allows nodes to quickly select optimized beam sequences without requiring complex real-time negotiations during the beamforming process itself. The speed is preserved because the coordination happens in advance through efficient signaling, not during the critical beamforming execution phase.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, from another network node, an indication of a first selected beam sequence associated with a first beamforming procedure. The network node may select, based at least in part on the indication of the first selected beam sequence, a second selected beam sequence associated with a second beamforming procedure performed by the network node. The network node may perform the second beamforming procedure based at least in part on the second selected beam sequence. Numerous other aspects are described.
