Abstract: A method includes: A basic application layer sends first information that includes a first business requirement and a first port to a basic service layer. The basic service layer sends second information that includes the first business requirement, a first broadcast business channel, and a logical channel type to an access layer. The first broadcast business channel is determined based on the first information. The access layer supports a first access technology that is determined, based on the first business requirement, from a plurality of access technologies supported by the access layer. The access layer sends a first mapping relationship that indicates the first broadcast business channel and a first logical channel to the basic service layer. The first logical channel is a logical channel that supports the first access technology and that is determined based on the second information.

Abstract: In an outbound transmission control method, a satellite network device segments an application layer packet into a plurality of Message Data Convergence Protocol (MDCP) protocol data units (PDUs) at an MDCP layer. The satellite network device sequentially delivers the MDCP PDUs to a satellite link control (SLC) layer as SLC service data units (SDUs) at the SLC layer, and segments the SLC SDU into N SLC PDUs at the SLC layer. SLC PDUs of one or more users are obtained at a physical layer (PHY) from the SLC layer. The SLC PDUs of the one or more users are spliced together at the PHY to form outbound data of a physical slot with a fixed length. The satellite network device in turn sends the outbound data to one or more terminals.

Abstract: A beam weight obtaining method and an apparatus. An aggregation path is generated by using energy of a plurality of paths to help improve quality of a generated beam, thereby improving an SNR and a capacity of a terminal device. The method includes: a network device obtains a plurality of paths that meet a multipath aggregation condition, where the multipath aggregation condition includes one or more of the following conditions: a condition that every two paths in the plurality of paths need to meet in space, and a condition that every two paths in the plurality of paths need to meet in power. The network device determines aggregation information based on the plurality of paths, where the aggregation information includes information required by the network device to generate an aggregation path corresponding to the plurality of paths.

Abstract: An array grouping-based communication method and a communication apparatus are provided. A first signal is received from a first communication device using M groups of analog weights, where at least two groups of analog weights in the M groups of analog weights are different, and M is an integer greater than or equal to 2. Channel estimation is performed based on the first signal to obtain M channel estimation results, where the M channel estimation results are arranged in one-to-one correspondence with the M groups of analog weights. Signal receiving or sending processing is performed based on the M channel estimation results using a target analog weight, where the target analog weight is obtained based on the M groups of analog weights.

Abstract: A method is applied to an electronic device. The electronic device includes a basic application layer, a basic service layer, and an access layer, the access layer includes a first access layer and a second access layer, and the first access layer and the second access layer support different data transmission capabilities. The method includes: The basic application layer requests the basic service layer to establish a service channel for a communication service of an application. The basic service layer establishes a transmission channel group for the communication service if the communication service supports multilink transmission. The transmission channel group includes a first service channel and/or a second service channel, the first service channel corresponds to the first access layer, and the second service channel corresponds to the second access layer. The electronic device transmits service data of the communication service based on the transmission channel group.
