Title:
IMPROVED UPLINK RESOURCE ALLOCATION AMONG DIFFERENT OFDM NUMEROLOGY SCHEMES
Document Type and Number:
WIPO Patent Application WO/2018/061438
Kind Code:
A1
Abstract:
The present disclosure relates to a resource allocation procedure, performed between a user equipment and radio base station. The UE is configured with at least one numerology scheme, each associated with parameters partitioning time-frequency radio resources into resource scheduling units differently. The UE is configured with logical channels each of which is associated with at least one numerology scheme. A receiver of the UE receives from the radio base station an uplink scheduling assignment, which indicates uplink radio resources usable by the UE. A processor of the UE determines for which numerology scheme the received uplink scheduling assignment is intended based on the received uplink scheduling assignment. The processor performs a logical channel prioritization procedure by allocating the assigned uplink radio resources to the configured logical channels and by prioritizing those logical channels that are associated with the numerology scheme for which the uplink scheduling assignment is intended.
