2025, 17, 1349 6 of 20 multi-layer perceptron (MLP) with a hidden layer for pre-training and a single linear layer for fine-tuning. The resulting sequence of embedding vectors serves as input to the encoder. The transformer encoder comprises multi-head self-attention (MSA) and MLP blocks,...
If the V2X system allows association procedures for some special STAs including the sensor STAs, V2X infrastructure STAs can allocate AIDs to the STAs. In this case, the V2X infrastructure STAs can trigger OFDMA transmissions of the special STAs by using a trigger frame with dedicated AIDs the ...
