    Abstract: A hybrid automatic repeat request acknowledgement (HARQ-ACK) processing method includes: selecting at least a part of HARQ-ACK bits as a first HARQ-ACK bit from a first HARQ-ACK codebook according to at least one of information indicated by DCI corresponding to the first HARQ-ACK codebook or indexes of carriers where PDSCHs corresponding to the first HARQ-ACK codebook are located, and according to at least one of a quantity of multiplexed HARQ-ACK bits or a code rate of HARQ-ACK transmission; and discarding the first HARQ-ACK bit; or determining a first HARQ-ACK bit from a first HARQ-ACK codebook according to at least one of the information indicated by the DCI or the indexes of carriers; and multiplexing the first HARQ-ACK bit and HARQ-ACK bits in a second HARQ-ACK codebook. The first HARQ-ACK bit is at least a part of HARQ-ACK bits in the first HARQ-ACK codebook.

    Abstract: A hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback method includes in a case that a first channel resource for a unicast HARQ-ACK is not configured for a terminal, feeding back, by the terminal by using a target channel resource for a multicast HARQ-ACK, the unicast HARQ-ACK and the multicast HARQ-ACK to a network-side device; or in a case that the first channel resource for the unicast HARQ-ACK is not configured for the terminal, feeding back, by the terminal by using a second channel resource for the unicast HARQ-ACK, the unicast HARQ-ACK and the multicast HARQ-ACK to the network-side device. The unicast HARQ-ACK and the multicast HARQ-ACK have a same priority and are fed back in a same time unit, and the first channel resource and the second channel resource are configured based on different configuration parameters.

    Abstract: A method for controlling a power for a PUCCH transmission, including determining, by a terminal, first UCI and second UCI multiplexed on one PUCCH for transmission, where a priority of the first UCI is a first priority, a priority of the second UCI is a second priority, and the first priority is higher than the second priority; and determining, by the terminal, a power for the PUCCH transmission based on a first bit number, where the first bit number is determined based on a bit number of the first UCI and/or a bit number of the second UCI.

    Abstract: A DCI size alignment method includes determining, by a communication device, whether a number of DCI sizes of a plurality of DCI formats meets a DCI size budget; and in a case that the DCI size budget is not met, performing a DCI size alignment operation on the plurality of DCI formats according to a DCI size alignment rule until the DCI size budget is met. The DCI size alignment rule includes at least one of: aligning a first DCI format with DCI 0_0 and/or DCI 1_0 in a CSS; aligning the first DCI format with DCI 1_1 and/or DCI 0_1 in a USS; aligning the first DCI format with DCI 1_2 and/or DCI 0_2 in the USS; aligning DCI 1_2 and/or DCI 0_2 in the USS with DCI 1_1 and/or DCI 0_1; or aligning the first DCI format with a group common DCI format in the CSS.

    Abstract: A PDCCH blind decoding method includes obtaining, by a UE, a configuration of a target search space set; and performing, by the UE, PDCCH blind decoding based on the configuration of the target search space set, where the target search space set meets a target condition; the target condition includes that a candidate PDCCH in the target search space set is not decoded when a decoding object corresponding to the candidate PDCCH in at least one transmission time unit exceeds a blind decoding capability of the UE; and the decoding object includes a CCE or a quantity of BD of candidate control channels.

    Abstract: The embodiments of the present invention provide a feedback information transmission method and a terminal device, which relate to the field of communications technologies and are used to resolve the problem of how a terminal device sends feedback information in a multi-TRP communications system. The method is applied to a terminal device and includes: in the case of receiving at least two PDCCHs sent by at least two TRPs or different antenna panels of one TRP, determining a target PUCCH resource, and sending target feedback information through the target PUCCH resource, where the target feedback information is feedback information of each PDSCH scheduled by the at least two PDCCHs. The embodiments of the present invention are used for the transmission of feedback information.
