communication between the bs and at least one ue connected therewith at the measurement location and a measurement of the at least one identified rb is below a predetermined threshold the measurement as mentioned above can be implemented by mues which are close to the hst and preferably in idle states based upon the instructions from the above bs i e menb because the hsr is stationary its location information e g coordinates of each section of the rail tracks can be provided to the menb before hand then the menb may apprise all mues of the location information via bch signaling according to the location information at issue the mues may determine whether they are close to the hsr or not by taking their current position into account in view of the fact that gps enabled ues are very common now it is easy for the ue to determine its own current position and make a judgment regarding whether it is sufficiently close to the hsr for example if the mue finds itself within the predetermined scope of 20 meters from the rail track upon which the mr node would travel in a very near future it will measure the channel state of the whole system bandwidth at its position the channel state may.
