A wireless communication method, comprising: sending, by a terminal device, a random access request to a network device on a high frequency uplink carrier or a supplementary uplink, SUL, carrier deployed at a frequency band lower than the high frequency uplink carrier; and acquiring, by the terminal device, a random access response, RAR, sent by the network device in response to the random access request, wherein the acquiring, by the terminal device, of the RAR sent by the network device in response to the random access request comprises: acquiring the RAR based on a random access radio network temporary identity, RA-RNTI, for the RAR, characterized in that a first RA-RNTI for the RAR of the SUL carrier is determined based on a calculation formula formed by adding, based on another calculation formula of a second RA-RNTI for the RAR of the high frequency uplink carrier, one factor associated with the SUL carrier, and wherein, when the random access request is sent on the high frequency uplink carrier, a value range of the first RA-RNTI is [x, y], where y > x≥0; when the random access request is sent on the SUL carrier, a value range of the second RA-RNTI is [x+Z, y+Z], where Z is the factor associated with the SUL carrier and greater than any value in a range from x to y. sending, by a terminal device, a random access request to a network device on a high frequency uplink carrier or a supplementary uplink, SUL, carrier deployed at a frequency band lower than the high frequency uplink carrier; and acquiring, by the terminal device, a random access response, RAR, sent by the network device in response to the random access request, wherein the acquiring, by the terminal device, of the RAR sent by the network device in response to the random access request comprises: acquiring the RAR based on a random access radio network temporary identity, RA-RNTI, for the RAR, characterized in that a first RA-RNTI for the RAR of the SUL carrier is determined based on a calculation formula formed by adding, based on another calculation formula of a second RA-RNTI for the RAR of the high frequency uplink carrier, one factor associated with the SUL carrier, and wherein, when the random access request is sent on the high frequency uplink carrier, a value range of the first RA-RNTI is [x, y], where y > x≥0; when the random access request is sent on the SUL carrier, a value range of the second RA-RNTI is [x+Z, y+Z], where Z is the factor associated with the SUL carrier and greater than any value in a range from x to y. acquiring the RAR based on a random access radio network temporary identity, RA-RNTI, for the RAR, characterized in that a first RA-RNTI for the RAR of the SUL carrier is determined based on a calculation formula formed by adding, based on another calculation formula of a second RA-RNTI for the RAR of the high frequency uplink carrier, one factor associated with the SUL carrier, and wherein, when the random access request is sent on the high frequency uplink carrier, a value range of the first RA-RNTI is [x, y], where y > x≥0; when the random access request is sent on the SUL carrier, a value range of the second RA-RNTI is [x+Z, y+Z], where Z is the factor associated with the SUL carrier and greater than any value in a range from x to y.
