Dynamic resource allocation among different ofdm numerology schemes

A method of a base station, the method comprising:

• transmitting, to a user equipment, configuration information indicating a first reference resource set and a second reference resource set, wherein the second reference resource set overlaps with the first reference resource set in at least one of a frequency domain or a time domain;
• the first reference resource set defining bounds of schedulable time-frequency radio resources that can be allocated according to a first numerology scheme out of a plurality of numerology schemes, the plurality of numerology schemes respectively partitioning time-frequency radio resources into resource scheduling units;
• the second reference resource set defining bounds of schedulable time-frequency radio resources that can be allocated according to a second numerology scheme out of the plurality of numerology schemes;
• and
• generating and transmitting, to the user equipment, resource allocation information,
• the resource allocation information indicating time-frequency radio resources of the first reference resource set that is allocated to the user equipment by the base station according to the first numerology scheme,
• wherein, the time-frequency radio resources allocated according to the first numerology scheme are re-allocated according to the second numerology scheme having a shorter scheduling time interval than the first numerology scheme, by overwriting the time-frequency radio resources allocated according to the first numerology scheme, wherein information on the overwritten time-frequency radio resources is broadcast.

An integrated circuit, which comprise circuitry configured to:

• control transmitting, to a user equipment, configuration information indicating a first reference resource set and a second reference resource set at a base station, wherein the second reference resource set overlaps with the first reference resource set in at least one of a frequency domain or a time domain;
• the first reference resource set defining bounds of schedulable time-frequency radio resources that can be allocated according to a first numerology scheme out of a plurality of numerology schemes, the plurality of numerology schemes respectively partitioning time-frequency radio resources into resource scheduling units;
• the second reference resource set defining bounds of schedulable time-frequency radio resources that can be allocated according to a second numerology scheme out of the plurality of numerology schemes;
• and
• control generating and transmitting, to the user equipment, resource allocation information,
• the resource allocation information indicating time-frequency radio resources of the first reference resource set that is allocated to the user equipment by the base station according to the first numerology scheme,
• wherein, the time-frequency radio resources allocated according to the first numerology scheme are re-allocated according to the second numerology scheme having a shorter scheduling time interval than the first numerology scheme, by overwriting the time-frequency radio resources allocated according to the first numerology scheme, wherein information on the overwritten time-frequency radio resources is broadcast.
