Abstract: This application discloses a multi-codeword transmission method and an apparatus. The method includes: generating, by a network device, downlink control information corresponding to each of a plurality of code words to be sent to a terminal device, where the downlink control information corresponding to each code word includes at least one of the following: a physical downlink shared channel resource element mapping and quasi-co-location indicator, and an antenna port(s), scrambling identity and number of layers; and sending, by the network device, downlink control information corresponding to the plurality of code words to the terminal device. Corresponding apparatuses are further disclosed. According to the technical solutions of this application, the network device generates the downlink control information corresponding to each of the plurality of code words to be sent to the terminal device, and the terminal device may demodulate data for the plurality of code words based on downlink control information corresponding to the plurality of code words. This ensures that the terminal device correctly demodulates data in a multi-codeword transmission scenario.

Abstract: This application provides a method and an apparatus for determining a cell activation delay. A terminal device or a network device may determine the cell activation delay corresponding to a to-be-activated cell based on that a downlink spatial filter of a downlink signal of the to-be-activated cell and a downlink spatial filter of a downlink signal of an activated cell are the same or different. In this way, the terminal device sends CSI within the activation delay. The network device is to receive the CSI within the activation delay, and determines, depending on whether the CSI is received, whether the to-be-activated cell is successfully activated, the terminal device and the network device can determine a proper activation delay, to avoid a case in which the terminal device and the network device mistakenly determine, due to an excessively long or excessively short activation delay, whether a secondary cell is successfully activated.
