Abstract
An embodiment herein discloses a method performed by a Base Station, BS. The BS determines a Hybrid Automatic Repeat Request-Acknowledgement, HARQ-ACK, codebook size for a User Equipment, UE, based on data to be transmitted in a data transmission to the UE. The HARQ-ACK codebook size indicates the number of HARQ-ACK bits that the UE encodes for transmitting Hybrid Automatic Repeat Request, HARQ, feedback for the data transmission to the BS. The BS further transmits an indication of the HARQ-ACK codebook size in a Downlink Assignment Index, DAI, field of a Downlink, DL, assignment to the UE.
