    Abstract: The present patent application provides a method, an apparatus, and a system for collaborative communication between a network device and two or more terminal devices. The network device receives a collaboration request from a first terminal device. The network device determines, according to the collaboration request, at least one second terminal device that may collaborate with the first terminal device in receiving downlink data. The network device sends an indication message to the first terminal device. The indication message instructs the first terminal device to receive a first part of the downlink data from the network device, and receive a second part of the downlink data, which is transmitted from the network device to the second terminal device, from the second terminal device.

    Abstract: This application relates to the field of communications technologies, and discloses a transport block generation method and apparatus. The method includes: determining a TBS based on an MCS of a receiving device, a resource characteristic of an RB allocated to the receiving device, and a quantity of symbols, where the quantity of symbols is a quantity of symbols included in each RB, and each RB includes a same quantity of symbols; and generating a TB based on a TBS. TBS is determined based on the MCS of the receiving device, a quantity of RBs allocated to the receiving device, and the quantity of symbols included in the RB, and the TB is generated based on the determined TBS. The quantity of symbols included in the RB is considered in determining the TBS. Therefore, the determined TBS may vary with the quantity of symbols included in the RB.
