Abstract: A signal generation method is disclosed, to enhance an anti-interference capability and a coverage area of a signal. The method includes: A first device obtains a first signal based on transmission information through channel encoding, where the transmission information includes information that the first device needs to send to a second device; the first device generates a second signal based on the first signal through repetition or frequency spread transformation; the first device generates a third signal based on the second signal through linear encoding; and the first device generates a target signal based on the third signal through signal modulation, where the target signal is sent to the second device. Associated devices are also described.

Abstract: Example transmit power determining methods and apparatus are described. One example method includes determining a first transmit power based on N time domain resources corresponding to a first transport block. The first transport block is sent on the N time domain resources at the first transmit power. The first transmit power is a transmit power of the first transport block on each of the N time domain resources, a size of the N time domain resources is greater than one slot, and N is a positive integer.

Abstract: A backscatter communication method and apparatus provides operation including: receiving a first excitation signal from a first device; determining a first resource based on a candidate resource; and sending a backscattered signal of the first excitation signal to a second device based on the first resource. This can reduce a probability of selecting a same resource as another device to some extent, so that a conflict is reduced, and an access success rate of a backscatter device can be improved.

Abstract: The present disclosure relates to communication methods. One example method includes within a first discontinuous reception (DRX) cycle, starting, by a terminal device, a first timer (for example, a DRX inactivity timer (drx-InactivityTimer)) when a physical downlink control channel (PDCCH) indicates a new transmission. When the first timer expires at or after a time position for sending an indication signal, the terminal device does not receive the indication signal, where the time position is configured by a network device for the terminal device, and the indication signal is used to indicate the terminal device to sleep.

Abstract: The present disclosure relates to data transmission methods and apparatuses. In one example method, a relay device receives configuration information from a network device, where the configuration information indicates to transmit a first signal and a second signal in a target time period, the first signal is a signal for communication between the relay device and the network device, and the second signal is a signal transmitted with assistance of the relay device. When at least one of the first signal or the second signal meets a first condition, the relay device transmits the first signal in the target time period. When at least one of the first signal or the second signal does not meet a first condition, the relay device transmits the second signal in the target time period.

Abstract: This application discloses a random access method and a corresponding apparatus. The method includes: A terminal device determines, based on a measurement result of a SS/PBCH block, a random access opportunity and a random access preamble that are associated with the synchronization signal/physical broadcast channel block. The terminal device sends a random access signal based on the random access opportunity and the random access preamble. There is a correspondence between the random access opportunity and/or the random access preamble and at least one of the following: a data subcarrier spacing ΔfData, or a ratio ΔfData/ΔfRA of a random access subcarrier spacing ΔfRA to the data subcarrier spacing ΔfData. At least one of the random access subcarrier spacing ΔfRA and the data subcarrier spacing ΔfData is greater than 120 kHz. This application provides a design of a random access signal based on a large subcarrier spacing, to improve communication performance.
