Title:
TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/093390
Kind Code:
A1
Abstract:
This terminal device receives RRC information indicating a maximum number X of CBGs per transport block and transmits an HARQ-ACK corresponding to a PDSCH. A transport block is split into a plurality of code blocks. The CBGs are classified as empty or non-empty. An empty CBG does not contain a code block, and a non-empty CBG contains at least one code block. A CBG group contains more than one CBG. If all the CBGs contained in the CBG group are empty, a NACK is generated for each empty CBG. If the CBG group contains at least one empty CBG and at least one non-empty CBG, a NACK is not generated for the at least one empty CBG. The CBG group contains more than one CBG, and HARQ-ACKs in response to the CBGs corresponding to the CBG group are generated as one bundled HARQ-ACK.
