Engineering Contradiction Analysis
1Reliability
If uniform power spectral density is used for beacon signals, then device complexity is reduced, but reliability of wireless communications deteriorates due to varying propagation channels and angle-frequency coupling
Solution Approach 1:
The patent applies local quality by configuring different power spectral density values for different subsets of resource elements within the beacon signal. Specifically, the first subset of resource elements is assigned a first power spectral density value while the second subset is assigned a second power spectral density value, allowing targeted optimization for different frequency regions affected by varying propagation channels and angle-frequency coupling effects.
2Reliability
If nonuniform power spectral density configuration is used for beacon signals, then reliability of wireless communications is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the resource elements carrying beacon signals into at least two distinct subsets. Each subset is then assigned a different power spectral density value, allowing the system to optimize performance for different frequency regions while maintaining manageable configuration complexity through structured segmentation.
3Reliability
If beam training procedures are performed to establish connections, then reliability of wireless communications is improved, but latency increases
Solution Approach 1:
The patent applies preliminary action by performing beam training procedures in advance to establish connections and determine optimal beams before actual data transmission begins. The nonuniform power spectral density configuration is also applied preliminarily to beacon signals to pre-optimize the communication link, reducing the need for repeated beam training and thereby reducing latency during actual communication.

AI summary
Methods, systems, and devices for wireless communication are described. A communication device, such as a base station or a user equipment (UE) may generate a beacon signal based on a nonuniform power spectral density configuration. The communication device may transmit control signaling indicating a nonuniform power spectral density profile associated with the beacon signal. The nonuniform power spectral density profile may indicate a respective power offset associated with the beacon signal for one or more subset of resource elements of a set of resource elements. The communication device may transmit the beacon signal. Additionally or alternatively, the communication device may receive control signaling indicating the nonuniform power spectral density profile associated with the beacon signal. Based on the nonuniform power spectral density profile, the communication device may receive the beacon signal.
