Abstract: A first communication apparatus receives training data, and determines a first intermediate gradient based on the training data. The first intermediate gradient is used to update a parameter of a first neural network located in a second communication apparatus. The first communication apparatus maps the first intermediate gradient to an air interface resource to generate a first gradient signal, and sends the first gradient signal to the second communication apparatus. The first gradient signal includes one or more first gradient symbols, and each of the first gradient symbols is corresponding to one or more gradient values.

Abstract: A method and a communication apparatus for determining a timing advance. A downlink signal is received from a network device. A first reference moment of a signal period of the downlink signal is determined, where the first reference moment includes a start receiving moment of the signal period. A first time interval between the start receiving moment and a start moment of a first period in which the terminal is located is determined. Based on the first time interval, determining whether a start sending moment of the signal period is within the first period, and determining the start sending moment, where a period is a duration distributed at an equal interval on a time axis. A timing advance is determined based on the start receiving moment and the start sending moment, and an uplink signal is sent based on the timing advance.

Abstract: Embodiments of this disclosure provide a hybrid automatic repeat request (HARQ) bitmap information feedback method and a related device. The method includes: A terminal receives indication information from an access network device, where the indication information is used to determine whether HARQ feedback is needed for a transmit block transmitted in a plurality of downlink transmission units. The terminal determines HARQ bitmap information based on the indication information, where the HARQ bitmap information includes HARQ feedback information of at least one target transmission unit, and the target transmission unit indicates a downlink transmission unit that needs HARQ feedback in the plurality of downlink transmission units. The terminal sends the HARQ bitmap information to the access network device.
