Engineering Contradiction Analysis
1Ease of manufacture
If fewer antenna modules are used to reduce cost, then device cost decreases, but performance in mmW frequency range deteriorates
Solution Approach 1:
The patent applies asymmetry by using an L-shaped antenna module configuration instead of traditional symmetric linear or planar arrays. The L-shape provides directional coverage along two perpendicular arms, enabling cost-effective single-module implementation while maintaining adequate beamforming performance for mmW communications in specific directional scenarios.
2Length of moving object
If L-shaped antenna module is used to improve directional communication range, then directional communication range increases, but beam management complexity increases
Solution Approach 1:
The patent implements dynamic beam management by introducing multiple beam management modes (first mode for wide frequency range with L-shaped module, second mode for narrow frequency range with linear/planar modules). The system dynamically selects the appropriate mode based on the antenna module configuration and operating frequency range, optimizing performance while managing complexity through adaptive configuration rather than fixed complex procedures.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message that indicates an antenna module configuration, the antenna module configuration indicating an antenna module format of the UE. The UE may perform a beam management procedure according to a beam management mode associated with a frequency range and corresponding to the antenna module format and may receive, based on the beam management procedure, an indication of a set of parameters for communications using the frequency range. The UE may communicate, based on the set of parameters, one or more messages using the frequency range and one or more antenna modules. Additionally, or alternatively, the UE may receive an indication of a resource allocation for a beam weighting procedure, the resource allocation corresponding to the antenna module format of the UE and may perform the beam weighting procedure using the resource allocation.
