Abstract: Example data transmission methods and apparatus are described. One example method includes determining an actual transmit power for first uplink data by a terminal device based on a determined channel transmit power and a transmission parameter. The actual transmit power is less than or equal to the channel transmit power, and the transmission parameter includes one or more of parameters that can be used to indicate a location of the terminal device. The terminal device sends the first uplink data at the actual transmit power. Therefore, the terminal device may determine the actual transmit power for the uplink data based on the channel transmit power and various transmission parameters that can indicate whether the terminal device is located at a cell edge, so that the actual transmit power for the uplink data can be flexibly adjusted.

The first signal is a signal modulated by using π/2 binary phase shift keying (BPSK). The first frequency-domain resource comprises K subcarriers each having a subcarrier number of k, k=u+L*n+delta, L is an integer greater than or equal to 2, delta∈{0, 1, . . . , L−1}, u is an integer, and subcarrier numbers of the K subcarriers are numbered in ascending or descending order of frequencies.
