Is TTI bundling enabled by default or on a specific condition enabled ?
Hi,
It is implementation specific, when an UE's up link channel is very poor then ENB can activate TTI bundling so that it will be effective.
On what parameter basis, eNodeB changes its current transmission mode to different transmission mode for an UE ? What parameters are considered to take decision on transmission mode ? Does the eNodeB inform to UE about the selected TM ?
Will ENB sends 4 ack/nack or how this will be handled?
