batch_size in Sionna

[weirdooo-18]

What does the batch_size refer to exactly? How does the number of batches given become the number of receivers (in Site-specific link level simulations)?

[SebastianCa]

The function sample_positions allows to sample batch_size random user positions from the coverage map. In this case, batch_size denotes the number of samples that are returned by the function (i.e., a tensor of shape [batch_size, 3] containing random (x,y,z) positions).

You can find a detailed example in the Introduction to Sionna RT notebook.
