摘要： This application provides an uplink acknowledgement information transmission method and apparatus, to resolve a problem that a large quantity of resources are consumed when a plurality of HARQ-ACK codebooks are reported. The method includes: A terminal device may obtain a plurality of first HARQ-ACK codebooks, where each of the plurality of first HARQ-ACK codebooks includes HARQ-ACK information of at least one downlink data channel, each first HARQ-ACK codebook corresponds to one first radio network temporary identifier RNTI, and first RNTIs corresponding to the first HARQ-ACK codebooks are different. Then, the terminal device may send a physical uplink channel to a network device, where the physical uplink channel carries a second HARQ-ACK codebook, the second HARQ-ACK codebook includes at least one of the plurality of first HARQ-ACK codebooks that are concatenated in a preset order, and the preset order is determined based on a plurality of first RNTIs corresponding to the plurality of first HARQ-ACK codebooks.

摘要： This application provides a physical broadcast channel transmission method and a related apparatus. The method includes: A network device determines downlink bandwidth configuration information corresponding to a terminal device; the network device sends a first physical broadcast channel to the terminal device in a plurality of cell acquisition subframes based on the downlink bandwidth configuration information, where a time interval between every two adjacent cell acquisition subframes in the plurality of cell acquisition subframes is greater than or equal to 30 ms. When a bandwidth configuration value corresponding to the downlink bandwidth configuration information is greater than or equal to a first threshold, the plurality of cell acquisition subframes in which the first physical broadcast channel is sent include at least one first cell acquisition subframe. At least five symbols of the first physical broadcast channel are transmitted in the first cell acquisition subframe.

摘要： This application provides a data transmission (including receiving and sending) method. The method includes: A terminal device receives downlink control information DCI, where cyclic redundancy check CRC of the DCI is scrambled by using a first RNTI, the DCI is used to schedule a first downlink data channel, and the first downlink data channel is scrambled by using a second RNTI; and the terminal device receives the first downlink data channel based on the DCI. The DCI includes a DAI domain and/or an FDRA domain. The DAI domain indicates a count of first HARQ-ACK information in a first HARQ-ACK codebook, and the first HARQ-ACK codebook corresponds to the first RNTI. The FDRA domain indicates, within a frequency domain range of a public frequency resource, a scheduled frequency domain resource on the first downlink data channel. The terminal device and a network device align understandings for the DAI domain and/or the FDRA domain, so that correct data transmission can be performed based on information in the DCI.

摘要： Embodiments of this application provide a communication method and an apparatus, relate to the communication field, and in particular, are applicable to a broadcast system. The method includes: A terminal device receives a first downlink channel from an access network device, where the first downlink channel is scrambled by using a first identifier and is used to carry first data. The terminal device receives a second downlink channel from the access network device, where the second downlink channel is scrambled by using a second identifier and is used to retransmit the first data. The first identifier and the second identifier are identifiers configured by the access network device. This method can implement a feedback retransmission mechanism combining broadcast initial transmission and partial retransmission, to further improve spectral efficiency of a communication system.

摘要： This application provides a TBS determining method and apparatus, to improve a signal transmission rate of a system. The TBS determining method is: determining, based on an MCS corresponding to a broadcast channel and a frequency domain resource occupied by the broadcast channel, a corresponding TBS in any one of the following manners: determining a TBS index based on an index of the MCS and a first table, determining a first intermediate variable based on the TBS index, the frequency domain resource, and a second table, and determining the TBS based on the first intermediate variable and a third table, where the third table includes a correspondence between the TBS and the first intermediate variable, the third table is corresponding to a TBS table in which a quantity of layers to which a transport block is mapped is greater than 1, and a quantity of layers to which a transport block carried on the first broadcast channel is mapped is 1; determining a second intermediate variable based on a determined TBS index, the frequency domain resource, and a second table, and determining the TB S based on the second intermediate variable and an scale factor, where the scale factor is greater than 1; or determining a quantity of REs based on the frequency domain resource, and determining the TBS based on the quantity of REs and an index of the MCS.
