An electrically controlled differential gear is disposed between a right front wheel and a left front wheel of a vehicle. The electrically controlled differential gear includes a clutch mechanism that limits a differential operation of the electrically controlled differential gear. A second ECU (control portion) obtains information as to failure associated with actuation of a right front electric brake mechanism. The second ECU obtains a physical amount relating to a required braking force which is applied to the left front wheel and the right front wheel. The second ECU outputs a differential limiting control command for limiting the differential operation of the electrically controlled differential gear to the clutch mechanism (or more specifically, a differential ECU that controls the clutch mechanism) based on the information as to the failure and the physical amount relating to the required braking force.

Dynamic resource allocation among different OFDM numerology schemes

The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.
