Title:
BASE STATION, APPARATUS, METHOD AND COMPUTER READABLE MEDIUM FOR MIXED-NUMEROLOGY CONFIGURATION SELECTION
Document Type and Number:
WIPO Patent Application WO/2022/249342
Kind Code:
A1
Abstract:
The requirement feature extractor (21) extracts statistical features related to service requirements of UEs. The traffic feature extractor (22) extracts statistical features related to incoming and outgoing traffic. The channel feature extractor (23) extracts statistical features related to a wireless channel condition and a wireless channel configuration. The context unit (24) generate a context vector based on the statistical features. The ML model array (25) estimates QoS for mixed-numerology configurations based on the context vector. The decision unit (26) selects a mixed-numerology configuration used for data transmission and data reception based on the estimated QoS.
