Abstract: A feedback information transmission method and apparatus, and the method includes receiving, by a terminal device, N pieces of first data from N first transmission points, where the N first transmission points are in a one-to-one correspondence with the N pieces of first data, each piece of first data includes at least one transport block, and the N pieces of first data are carried on a same carrier, where N≥2, and sending, by the terminal device, feedback information of the N pieces of first data on at least one time-frequency resource such that acknowledgement (ACK)/negative ACK (NACK) feedback in coordinated multipoint multi-stream transmission can be implemented.

Abstract: A data transmission method and apparatus are provided. A terminal device obtains an antenna port allocation result indicating a first antenna port set and a second antenna port set. An antenna port in the first antenna port set is quasi co-located (QCL) with another antenna port in the first antenna port set, an antenna port in the second antenna port is QCL with another antenna port in the second antenna port set, and an antenna port in the first antenna port set is not QCL with an antenna port in the second antenna port set. The terminal device receives first data transmitted on an antenna port in the first antenna port set, and receives second data transmitted on an antenna port in the second antenna port set.
