Abstract: A transmit end obtains a frequency hopping parameter and resource allocation information of a to-be-transmitted message, where the frequency hopping parameter includes at least one of bandwidth part indication information, beam indication information, reference signal configuration information, subcarrier spacing indication information, transmission waveform indication information, slot type indication information, channel type indication information, and transmission carrier indication information. The transmit end determines, based on the resource allocation information and the frequency hopping parameter, a physical resource used to send the to-be-transmitted message, where the physical resource includes information about a frequency domain resource on which the to-be-transmitted message is mapped in at least one time unit. The transmit end sends the to-be-transmitted message by using the physical resource.

Abstract: This application discloses a carrier switching solution for multi-carrier communication. A network device sends configuration information to a terminal. The configuration information includes first uplink carrier information and second uplink carrier information. The first uplink carrier information indicates that a first uplink carrier is an SRS switching-from uplink carrier. The second uplink carrier information indicates that a second uplink carrier is an SRS switching-to uplink carrier. At least one of the first uplink carrier and the second uplink carrier belongs to a cell including a supplementary uplink (SUL) carrier. The terminal may determine the SRS switching-from uplink carrier and the SRS switching-to uplink carrier in a plurality of configured uplink carriers based on the configuration information.

Abstract: Example information transmission methods and apparatus are described. One example method includes receiving higher layer signaling and downlink control information. A time-frequency resource corresponding to scheduling request (SR) information and a time-frequency resource corresponding to hybrid automatic repeat request (HARQ) information are respectively determined based on the higher layer signaling and the downlink control information; The SR information is sent by using a first time-frequency resource, and the HARQ information is sent by using a second time-frequency resource. The first time-frequency resource is a part of the time-frequency resource corresponding to the SR information and does not overlap the second time-frequency resource in time domain, and the second time-frequency resource is the time-frequency resource corresponding to the HARQ information. Alternatively, the HARQ information is sent by using the time-frequency resource corresponding to the HARQ information, where the SR information is not sent.

Abstract: Embodiments of this application disclose a message transmission method and apparatus, a terminal, and a base station. In the method, a symbol or symbol group may be used as a granularity to select a plurality of symbols or symbol groups from one or more slots and then allocate the plurality of symbols or symbol groups to a same terminal for transmitting data. The plurality of symbols or symbol groups may be used for uplink data scheduling or may be used for downlink data scheduling. Therefore, a slot resource is allocated at a small granularity, so that a time domain resource is more flexibly allocated, and the slot resource is more fully utilized. This helps improve message transmission efficiency, thereby expanding a coverage area.

Abstract: A neural network system includes P computing units configured to perform an operation of a first neural network layer and Q computing units configured to perform an operation of a second neural network layer. The P computing units are configured to perform computing on first input data based on N configured first weights to obtain first output data after receiving the first input data. The Q computing units are configured to perform computing on second input data based on M configured second weights to obtain second output data after receiving the second input data. The second input data includes the first output data. A ratio of N to M corresponds to a ratio of a data volume of the first output data to a data volume of the second output data.
