Abstract: A signal transmission method, a related device, and a system are provided. The method includes a terminal receiving configuration information, where the configuration information indicates N sets of power control parameters configured for M uplink resources or uplink resource sets, where M≥1, M is a positive integer, N>1, and N is a positive integer; and the terminal transmits an uplink signal on the M uplink resources or uplink resource sets, where transmission power for transmitting the uplink signal on the M uplink resources or uplink resource sets is determined based on a first power control parameter, and the first power control parameter is selected from the N sets of power control parameters. According to the foregoing solution, uplink transmission power can be more flexibly adjusted, and power efficiency in uplink transmission and uplink transmission performance can be maximized.

Abstract: This application discloses a reference signal configuration method and apparatus. Before a network device sends reference signals aperiodically, the network device sends configuration information to a terminal device, where the configuration information is used to indicate a timeslot offset of one or more reference signal resource sets. Therefore, the network device can flexibly send reference signals in different timeslots, thereby reducing a quantity of times of reference signal triggering and measurement result reporting, and improving efficiency of a communications system.

Abstract: This application discloses a data transmission solution. A terminal device generates channel state information and data for transmission in a data channel. The transmit power of the data channel is determined based on the number of bits used to transmit the data and the number of bits used to transmit the channel state information. The solution of this application reduces bit error probability and improves data decoding accuracy.

Abstract: A channel quality information transmission method and system are described. A terminal device determines a reporting priority of channel quality information according to a reporting priority rule when reporting of first channel quality information conflicts with reporting of second channel quality information. The device further determines to-be-reported content or to-be-discarded content based on the reporting priority of the channel quality information. The terminal device reports the to-be-reported content to a network device.
