Systems and methods for determining feedback codebook

A wireless communication apparatus comprising:

• at least one processor configured to:
• determine that first feedback information indicated to transmit on a first uplink (UL) resource is canceled;
• combine the first feedback information with second feedback information indicated to transmit on a second UL resource to generate combined feedback information, wherein combining the first feedback information with the second feedback information comprises performing an “OR” operation on a feedback bit in the first feedback information and a feedback bit in the second feedback information, that each corresponds to a same downlink (DL) slot;
• and
• transmit the combined feedback information using the second UL resource.

A wireless communication method, comprising:

• determining, by a base station, that first feedback information indicated to transmit on a first uplink (UL) resource is canceled;
• receiving, by the base station from a wireless communication device, combined feedback information comprising the first feedback information and second feedback information, wherein
• the combined feedback information is obtained by performing an “OR” operation on a feedback bit in the first feedback information and a feedback bit in the second feedback information, that each corresponds to a same downlink (DL) slot;
• the combined feedback information is received on second UL resource originally indicated for transmitting the second feedback information;
• the first feedback information provides feedback for first DL data transmitted to the wireless communication device;
• and
• the second feedback information provides feedback for second DL data transmitted to the wireless communication device.
