Abstract: Embodiments of this application provide a synchronization signal block transmission method and a communications apparatus. The method includes: A network device sends an SSB to a terminal device in a resource position of the SSB. Correspondingly, the terminal device receives the SSB. In this process, a symbol included in the resource position of the SSB does not overlap with an uplink symbol in a plurality of self-contained slot structures as much as possible. This method can reduce a probability that the symbol included in the resource position of the SSB conflicts with an uplink symbol in as many self-contained slot structures as possible, to avoid cross interference, and therefore can support reliable transmission in as many self-contained slot structures as possible.

Abstract: Embodiments of this application provide a method for processing information bits in a wireless communication network. A communication device receives a radio resource control (RRC) signaling, wherein the RRC signaling comprises time window information and time unit format information, wherein the time window information comprises a hybrid automatic repeat request (HARQ) time sequence K1 set, wherein K1 is a time relationship between a time unit of a physical downlink shared channel (PDSCH) and a time unit of a physical uplink control channel (PUCCH), or wherein the K1 is a time relationship between a time unit of a (PDSCH) and a time unit of a physical uplink shared channel (PUSCH). The device determines HARQ feedback information based on the time window information and the time unit format information and sends the HARQ feedback information.

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.

Abstract: Various embodiments provide a communication method and a communications apparatus. In those embodiments, a terminal device receives first indication information and second indication information from a network device. The first indication information indicates a position of a first reference point, the second indication information indicates a first quantity, the first quantity is a quantity of offset units between the first reference point and a second reference point, and the second reference point is an endpoint of a first physical resource block (PRB). The terminal device determines a position of the first PRB based on the first indication information, the second indication information, and an identifier of a subcarrier corresponding to the first reference point. Therefore, the terminal device can complete, without learning of a system bandwidth, a process of determining a PRB corresponding to a start point of a PRB number in the system bandwidth.
