    摘要： The present invention relates to the field of wireless communications technologies, and in particular, to a terminal, an access network device, a wireless communications system, and an uplink control information transmission method. In the terminal, a receiving module receives downlink scheduling information of a downlink subframe F(i, j), where a set M of preconfigured downlink subframes in which the downlink subframe F(i, j) is located is divided into N subsets of preconfigured downlink subframes, a bit quantity of a hybrid automatic repeat request-acknowledgement HARQ-ACK that needs to be fed back for each downlink subframe in one subset of preconfigured downlink subframes is a predetermined value, and bit quantities of HARQ-ACKs that need to be fed back for any downlink subframes in different subsets of preconfigured downlink subframes are different; a processing module generates a HARQ-ACK codebook according to a receiving status of downlink data, and generates uplink control information after encoding the HARQ-ACK codebook; and a sending module sends the uplink control information. Therefore, a case in which bit quantities of HARQ-ACKs that need to be fed back for downlink subframes on different to-be-aggregated carriers are different is supported.

    摘要： The present invention relates to a method and an apparatus for sending and receiving a downlink data block of a packet data service. A network side adds indication information of downlink data modulation modes to a downlink data block, where the downlink data block includes first information and second information; the network performs symbol mapping processing on the first information by using a first modulation mode to obtain a first modulated signal; the network performs symbol mapping processing and data pre-processing on the second information by using a second modulation mode to obtain a second modulated signal; the network combines these two modulated signals to obtain an aggregate modulated signal; and the network sends the aggregate modulated signal. A terminal performs demodulation to obtain a raw downlink data block. With the present invention, throughput of downlink data is increased while a USF compatibility between more types of low-capability mobile terminals is considered.
