Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the memory circuit stores both compressed CSI and raw CSI simultaneously, then the data storage capacity requirement increases, but the available memory capacity becomes insufficient
Solution Approach 1:
The patent implements dynamic memory allocation where the memory circuit alternates between storing compressed CSI and raw CSI based on operational requirements. The processing circuit controls the channel detection number and manages memory allocation dynamically, switching between different data types as needed rather than allocating fixed memory space for each type simultaneously.
Solution Approach 2:
The patent employs a mechanism where compressed CSI is removed from memory to make space for raw CSI when needed. The processing circuit monitors memory capacity and selectively deletes stored compressed CSI data, allowing the system to recover memory space and continue operations without expanding physical memory capacity.
2Productivity
If the channel detection number is maintained high, then the communication efficiency is improved, but the memory capacity for storing compressed CSI increases
Solution Approach 1:
The patent changes the parameter of channel detection number dynamically based on memory availability. When memory capacity is constrained, the processing circuit adjusts the channel detection number downward, allowing the system to operate efficiently within available resources rather than maintaining a fixed high detection number that would require excessive memory.
Solution Approach 2:
The system dynamically adjusts operational parameters including channel detection number and memory allocation based on real-time conditions. This dynamic adaptation allows the system to maintain optimal communication efficiency while accommodating varying memory capacity requirements through flexible parameter modification.

AI summary
The present invention discloses a wireless communication apparatus having memory sharing mechanism that includes a communication circuit, a memory circuit and a processing circuit. The processing circuit performs the steps outlined below. Remote wireless communication apparatuses are connected to perform channel detection and communication thereon by a communication circuit. Compressed channel state information (CSI) generated by the remote wireless communication apparatuses is received by the communication circuit. The compressed CSI is stored in the memory circuit. Raw CSI is generated according to a status of the wireless channel. When a remaining capacity of the memory circuit is not sufficient, a number of the remote wireless communication apparatuses that the communication circuit performs the channel detection thereon is decreased and the corresponding compressed CSI stored in the memory circuit is removed. The raw CSI is stored in the memory circuit.
