Abstract: Methods, apparatus, and systems for data or information transmission are provided. In one aspect, a data sending method by a terminal device includes: determining indication information, determining, based on the indication information, a transport block size (TBS) used to send data, and sending the data based on the determined TBS. The terminal device can determine at least two of first information indicating that the TBS is a first TBS, second information indicating that the TBS is a second TBS, or third information indicating the terminal device to select a TBS from a TBS set as a third TBS used by the terminal device to send data. The TBS set is determined based on the first TBS, and can include at least one of the second TBS or the third TBS. The indication information includes one of the at least two of the first, second, or third information.

Abstract: A communication method and an apparatus are disclosed, and the method includes: receiving, by a terminal, first indication information sent by a first network device; and if the first indication information indicates the second network device supports the enhanced signal transmission, receiving, by the terminal, an enhanced downlink signal sent by the second network device, where the second network device is a neighboring network device of the first network device. This avoids a technical problem that a delay is relatively long because the terminal still receives a downlink signal in an existing manner when the terminal cannot accurately obtain whether the second network device supports the enhanced signal transmission.

Abstract: A method includes: sending, by a first network device, a first configuration message to a terminal device, where the first configuration message is used to instruct the terminal device to configure a second ciphering/deciphering function associated with a second network device and share a first data packet numbering/reordering function, and the terminal device is configured with the first data packet numbering/reordering function and a first ciphering/deciphering function associated with the first network device; and receiving, by the first network device, a first configuration complete message sent by the terminal device. In this embodiment, the first configuration message is used so that the terminal device may configure the function associated with the second network device. Therefore, during handover, the terminal device may simultaneously perform data transmission with the second network device and the first network device, to reduce or avoid a service interruption time caused by handover.
