Abstract: Embodiments of this application provide a rendering method and apparatus, and the like. The method includes: A processor (which is usually a CPU) modifies a rendering instruction based on a relationship between a first frame buffer and a second frame buffer, so that a GPU renders a rendering job corresponding to the first frame buffer to the second frame buffer based on a new rendering instruction. In this application, render passes of one or more frame buffers are redirected to another frame buffer. In this way, memory occupation in a rendering process of an application program is effectively reduced, bandwidth of the GPU is reduced, and power consumption can be reduced.

Abstract: This application provides a method and an apparatus that are for transmitting data in a random access process. The method includes sending a message 1 to a network device. The method further includes receiving a message 2 sent by the network device, where the message 2 includes uplink grant information, where the uplink grant information includes first indication information, and where the first indication information is used to indicate a largest transport block size TBS allowed for a message 3. The method includes determining a target TBS in candidate TBSs based on the allowed largest TBS, where the target TBS is less than or equal to the allowed largest TBS. The method further includes sending the message 3 to the network device, where the message 3 includes uplink data transmitted based on the target TBS.

Abstract: This application provides a system message transmission method, an apparatus, and a system. A first communications device configures a MIB message, and the MIB message may carry various different information used to transmit a SIB1, for example, any one or more of scheduling information, first information, and an operation mode of a carrier, so that a second communications device receives the SIB1 based on the MIB message. The first communications device may flexibly configure information used to transmit the SIB1. In addition, when configuring the MIB message, the first communications device may consider ensuring, through configuration or implicit indication, that resource locations for transmitting SIB1s of different cells in one period are different. This type of interference isolation mechanism can avoid mutual interference between transmission of SIB1s of different cells, so that transmission reliability of the SIB1s can be improved.
