Abstract: This application provides example communication methods, terminal devices, and network devices. One example method includes configuring, by a network device, a first bandwidth part BP and a second BP for a terminal device. The network device then sends a first TB to the terminal device. When the first BP and the second BP correspond to a same physical parameter, the first TB is mapped onto the first BP and the second BP. When the first BP and the second BP correspond to different physical parameters, the network device further sends a second TB to the terminal device, where the first TB is mapped onto the first BP, and the second TB is mapped onto the second BP.

Abstract: This application provides a method for generating hybrid automatic repeat request HARQ information and an apparatus. The method includes: A terminal device receives a first message sent by a network device. The first message is used to indicate that there is a bandwidth part BWP combination in a cell, the BWP combination includes an active BWP, and the BWP corresponds to a set of unified parameters. The terminal device generates HARQ information based on the unified parameters corresponding to the BWP combination. This application provides a method for generating HARQ information when there are a plurality of active BWPs.

Abstract: A method and an apparatus for switching a cell state are provided, and relate to the field of communication technologies. The method includes: A terminal device receives a first instruction from a network device, and switches a serving cell state based on the first instruction. The first instruction indicates to switch the serving cell state of the terminal device to or from a first state. When the serving cell state is the first state, a downlink carrier of a serving cell supports downlink communication, and an uplink carrier of the serving cell does not support uplink communication.

Abstract: A method for determining time information is disclosed. The method includes: obtaining, by a network node, information sent by a terminal device; and determining, by the network node, at least one of the following based on the information: a first time interval between downlink scheduling and downlink data transmission, a second time interval between the downlink data transmission and a feedback message sent by the terminal device after the terminal device receives downlink data, and a third time interval between uplink scheduling and uplink data transmission, where the information may include at least one of a subcarrier spacing, an operating band, and a bandwidth that are supported by the terminal device, and further include a first smallest value and/or a second smallest value and/or a third smallest value corresponding to the at least one item. Therefore, flexibility and accuracy of determining the time information are improved.

Abstract: A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.
