1. An electronic device, comprising processing circuitry configured to:
upon determining that a partial hybrid automatic repeat request (HARQ) process between the electronic device and a user equipment are configured to not transmit feedback information, configure a type of a code book to be used by the user equipment to transmit feedback information as a dynamic code book or a semi-persistent code book; and
transmit information representing the type of the code book to the user equipment,
wherein the electronic device configures a default value of the type of the code book as the dynamic code book, such that upon determining that the user equipment receives no information representing the type of the code book from the electronic device, the type of the code book used by the user equipment to transmit the feedback information is the dynamic code book,
wherein, upon determining that the type of the code book is configured as the dynamic code book, the processing circuitry is further configured to perform at least one of a first process or a second process
wherein the first process comprises:
determining a downlink assignment indicator (DAI) value for uplink assignment according to:
numbers of a dynamic scheduling Physical Downlink Shared Channel (PDSCH) and a semi-persistent scheduling (SPS) PDSCH which are carried by a HARQ process corresponding to the uplink assignment and configured to transmit feedback information,
a number of SPS release signaling corresponding to SPS PDSCHs which are carried by the HARQ process corresponding to the uplink assignment and configured to transmit feedback information and a HARQ process configured to not transmit feedback information, and
a number of SPS activation signaling corresponding to a SPS PDSCH which is carried by the HARQ process configured to not transmit feedback information, and
wherein the second process comprises:
determining a downlink assignment indicator (DAI) value for downlink assignment according to:
a number of a dynamic scheduling Physical Downlink Shared Channel (PDSCH) which is carried by a HARQ process corresponding to the downlink assignment and configured to transmit feedback information,
a number of semi-persistent scheduling (SPS) release signaling corresponding to SPS PDSCHs which are carried by the HARQ process corresponding to the downlink assignment and configured to transmit feedback information and a HARQ process configured to not transmit feedback information, and
a number of SPS activation signaling corresponding to a SPS PDSCH which is carried by the HARQ process configured to not transmit feedback information.
