Beam tracking

Yes

No

Yes

Range of beam search (whole range is indicated as \({\Omega _{beams}}\))

Beam is selected from \({\Omega _{beams}}\) based on point-to-point as scenario cognition deepens

Beam is selected from \({\Omega _{beams}}\) based on exhaustion

Beam is selected from \({\Omega _{beams}}\) based on the previous prediction

Complexity of computation

\(O(({N_{b1})}^{{W_{b1}}})\)

\(O({N_{b2}}{{W_{b2}}})\)

Training datasets
