Engineering Contradiction Analysis
1Productivity
If beamforming communications are implemented over mmWave channels, then data transmission rates are improved, but communication reliability deteriorates due to channel instability and blocking
Solution Approach 1:
The patent applies preliminary action by implementing beamforming training before actual data transmission. The training protocol establishes optimal beam directions and parameters in advance, allowing the system to achieve high data transmission rates while maintaining reliability during subsequent communications. The training phase prepares the communication channel by determining best beam configurations, which then enable efficient data transfer without repeated trial-and-error adjustments.
2Reliability
If beamforming training is performed, then communication reliability is improved, but transmission time increases
Solution Approach 1:
The patent implements periodic action through structured training sequences that occur at regular intervals. The beamforming training is performed periodically rather than continuously, allowing the system to maintain reliability through scheduled calibration while minimizing time loss. Training sequences are repeated at optimal intervals to ensure channel conditions remain favorable without unnecessary continuous training overhead.
Solution Approach 2:
The training protocol performs all necessary beam configuration determinations in advance before data transmission begins. By completing beam selection and optimization during the training phase, the system eliminates the need for time-consuming real-time adjustments during actual communication, thereby reducing overall time loss while maintaining high reliability.
3Reliability
If training fields are appended to packets, then beamforming performance is improved, but packet complexity increases
Solution Approach 1:
The patent applies segmentation by separating the training function into a distinct field within the packet structure. The training field is appended as a separate segment from the data payload, allowing beamforming optimization without complicating the main data transmission function. This modular approach enables the training components to be independently designed, transmitted, and processed, reducing overall packet processing complexity while maintaining beamforming performance.

AI summary
For example, a millimeterWave (mmWave) wireless communication station (STA) may be configured to transmit a preamble of a packet over a mmWave wireless communication channel, the preamble including a Short Training Field (STF), a Long Training Field (LTF) after the STF, and a Signal (SIG) field after the LTF, wherein the SIG field includes a presence indicator configured to indicate that the packet includes a Training (TRN) field configured for Beamforming (BF) training; and to transmit the TRN field of the packet over the mm Wave wireless communication channel, the TRN field is after the SIG field, the TRN field including a plurality of TRN subfields, wherein a TRN subfield includes at least one of the STF or the LTF.
