Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems with heterogeneous networks, terminals cannot timely report their antenna polarization parameters to the network devices, leading to polarization loss and degraded communication quality due to mismatched polarization types.
Innovation Solution
A communication method where terminals send a first access message to network devices based on their polarization parameters, allowing the network devices to obtain these parameters implicitly, thereby improving the timeliness of polarization parameter reporting.

Engineering Contradiction Analysis
1Loss of time
If the terminal reports antenna polarization parameters through traditional methods, then the network device can obtain the parameters, but the reporting is not timely leading to polarization loss
Solution Approach 1:
The terminal device determines the polarization parameter before sending the access message, and embeds it in the access message itself. This preliminary action ensures the network device obtains the parameter at the earliest possible moment (during access), eliminating the time delay of traditional post-access reporting methods while ensuring communication quality is maintained from the start.
Solution Approach 2:
The patent combines the polarization parameter reporting function with the existing access message transmission process. Instead of separate reporting and accessing procedures, the parameter is embedded within the access message (specifically in the preamble or message 1), merging two functions into one efficient operation that reduces time loss without compromising reliability.
2Device complexity
If the terminal sends access message without polarization parameter, then the access process is simple, but polarization loss occurs due to parameter mismatch
Solution Approach 1:
The patent changes the structure of the access message by incorporating the polarization parameter into it. The parameter can be embedded in the preamble sequence selection or in specific fields of message 1, transforming the access message from a simple connection request to a compound message that carries both access information and polarization configuration, thereby preventing polarization loss while maintaining reasonable complexity.
Solution Approach 2:
The access message is designed to serve multiple functions simultaneously: establishing the communication connection and conveying the polarization parameter. This multi-functionality approach allows the same message structure to handle both access control and parameter reporting, avoiding the need for separate dedicated parameter reporting mechanisms and thus preventing polarization loss without significantly increasing complexity.
3Loss of information
If the network device waits for separate parameter reporting, then the access message remains simple, but communication quality degrades due to delayed parameter acquisition
Solution Approach 1:
The network device is configured to extract the polarization parameter directly from the received access message (preamble or message 1) without waiting for separate reporting. This preliminary acquisition of parameter information allows immediate compensation for polarization effects, eliminating information loss delays while the message processing complexity remains manageable due to the structured embedding of the parameter in well-defined message fields.
