Innovation Solution
A beam control method and apparatus that involve a wireless auxiliary device receiving configuration information from a network side device, which includes reference operating state information for a reference beam.

Engineering Contradiction Analysis
1Strength
If optimal beamforming is used to maximize serving cell signal, then signal strength of serving cell is improved, but interference signal strength of neighboring cell increases
Solution Approach 1:
The patent applies preliminary anti-action by pre-configuring reference operating state information for reference beams of both serving cells and neighboring cells. The network side device sends this reference information to the wireless auxiliary device in advance, enabling the auxiliary device to proactively adjust its beamforming to counteract potential interference before it degrades signal quality. This allows the system to maximize serving cell signal while preemptively suppressing neighboring cell interference.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting operating state information based on reference beam parameters. The wireless auxiliary device determines target operating state information by comparing reference operating state information with current signal conditions, and modifies beamforming parameters accordingly. This enables the system to adapt beamforming parameters to maximize desired signals while minimizing interference through continuous parameter optimization.
2Power
If beamforming adjusts signal forwarding state of each hardware unit, then beamforming gain is improved, but complexity of beam control increases
Solution Approach 1:
The patent applies preliminary action by having the network side device pre-calculate and send reference operating state information for reference beams before the wireless auxiliary device needs to perform beamforming. This reference information serves as a template that simplifies the auxiliary device's task, as it only needs to determine target operating state based on pre-provided reference data rather than calculating everything from scratch. This reduces computational complexity while maintaining high beamforming gain.
Solution Approach 2:
The patent uses reference operating state information as an intermediary between the network side device and the wireless auxiliary device. This reference information acts as a mediator that translates complex beamforming requirements into simplified target operating state determinations. The wireless auxiliary device uses this intermediary reference data to efficiently adjust its beamforming without directly handling the full complexity of multi-cell interference management.
