Title:
WIRELESS COMMUNICATION DEVICE, RU SELECTION DEVICE, METHOD, AND COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/171510
Kind Code:
A1
Abstract:
A resource unit, RU, selection device used in a wireless communication device is provided. A data processing unit (401) generates device state information based on carrier sensing data and acknowledgement signals received from an access point. A feature extraction and scoring unit (402) extracts features from the device state information and generates scores for each RU representative of possibility of successful transmission based on the extracted features. A reward computation unit (403) computes reward for providing feedback on prediction accuracy of the scores. A controller (404) determines a RU used to transmit data based on the scores. The controller (404) stores experiences including the device state information and the reward in a memory unit (405). The controller (404) updates parameters of the feature extraction and scoring unit (402) based on the experiences stored in the memory unit (405).
