Abstract:
The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.
