Abstract: The present disclosure relates to reference signal sending methods, signal detection methods, and apparatus. One example method includes determining an initial seed parameter of a pseudo-random sequence, and generating the pseudo-random sequence based on the initial seed parameter, where the initial seed parameter is determined based on attribute information of a terminal device, determining a cyclic shift value based on the pseudo-random sequence, and determining a reference signal based on the cyclic shift value, and sending the reference signal to a network device.

Abstract: An electronic device includes a processor, a volatile memory, and a non-volatile memory. The non-volatile memory stores a first operating system, and the electronic device works in a first working mode and a second working mode. When the electronic device is in the first working mode, a second operating system is run in the volatile memory. When the processor detects that the electronic device reaches a preset condition for entering the second working mode, the non-volatile memory is enabled, and non-system data in the volatile memory is moved to the non-volatile memory. The non-system data does not include the second operating system. After the movement of the non-system data is completed, the volatile memory is disabled, and the first operating system is run in the non-volatile memory, so that the electronic device enters the second working mode.

Abstract: This application provides example reference signal (RS) transmission methods and example communication apparatuses. One example reference signal transmission method includes receiving, by a terminal device, first information in a first time unit, where the first information triggers the terminal device to transmit a RS. The terminal device can then transmit the RS in a second time unit, where the second time unit is indicated by a time offset indicator n in valid uplink transmission time units starting from the first time unit.
