Method and apparatus for transmission configuration indicator (TCI) state activation and deactivation

A wireless communication device comprising:

• a memory storing instructions;
• and
• a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the wireless communication device to:
• receiving a signaling message comprising first information and second information, wherein:
• the first information comprises a downlink control channel resource group identifier (ID);
• the second information comprises a table of a transmission configuration indicator (TCI) indication field value corresponding to downlink control information (DCI);
• and
• the second information corresponds to the first information;
• determining, according to the second information, whether hybrid automatic repeat request acknowledgement (HARQ-ACK) codebooks corresponding to the first information with different indexes are combined;
• and
• in response to determining that the HARQ-ACK codebooks corresponding to the first information with the different indexes are combined:
• connecting, according to the different indexes, the HARQ-ACK codebooks corresponding to the different indexes,
• inputting the connected HARQ-ACK codebook to a channel encoder,
• encoding the connected HARQ-ACK codebook, and
• feeding back the encoded HARQ-ACK codebook in one uplink control resource.
