Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in optimizing signal transmission and reception due to the limited ability of devices to scan in multiple directions simultaneously, leading to inefficient resource usage and potential signal loss.
Innovation Solution
The network node configures transmissions based on the directional reception scanning ability of wireless communication devices, allowing for tailored beamforming configurations and TRP selection to optimize signal reception, either by using omnidirectional transmissions or multiple simultaneous directions, depending on the device's capabilities.

Engineering Contradiction Analysis
1Productivity
If the network uses directional beamforming transmission, then signal transmission efficiency is improved, but the device's ability to receive signals from multiple directions simultaneously is limited, leading to potential signal loss
Solution Approach 1:
The network node dynamically adapts transmission beamforming configuration based on the device's reception scanning ability. The system transitions between different transmission modes (omnidirectional vs. directional beamforming) depending on device capability, making the transmission strategy flexible and adaptive rather than fixed
Solution Approach 2:
The network changes transmission parameters (beamforming configuration, TRP selection) based on the device's reception capability parameters. By adjusting transmission parameters to match device reception abilities, the system optimizes both transmission efficiency and reception reliability
2Area of stationary object
If the network performs comprehensive beam sweeping in multiple directions, then signal coverage is improved, but resource consumption increases
Solution Approach 1:
Instead of performing complete beam sweeping in all directions for all devices, the network performs partial beam sweeping only in directions where needed based on device reception capabilities. This reduces unnecessary resource consumption while maintaining adequate coverage
Solution Approach 2:
The network adjusts beamforming parameters and transmission configuration based on device capability information, optimizing the balance between coverage area and resource consumption for each device
3Ease of operation
If the network configures transmissions without considering device scanning ability, then network operation simplicity is maintained, but access performance deteriorates
Solution Approach 1:
The device reports its reception scanning ability to the network in advance during initial signaling. This preliminary information exchange allows the network to configure optimal transmissions without complex real-time adjustments, maintaining operational simplicity while improving access performance

AI summary
A base station or other network node configures a network transmission in dependence on a directional scanning reception ability of a wireless communication device targeted by the transmission. An example transmission configuration is selecting or restricting which Transmission/Reception Point to use for the transmission or selecting or restricting the beamforming configuration to use for the transmission. The device complements operations in the wireless communication network by indicating its directional scanning reception ability in initial signaling, such as used for random access, or in Radio Resource Control signaling, or both.
