Claim 5:
6. A terminal device, comprising one or more processors, memory storing a plurality of programs to be executed by the one or more processors, an output interface and an input interface, wherein
the output interface is configured to send 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
the input interface is configured to acquire a random access response (RAR) sent by the network device in response to first random access request,
wherein the input interface is configured to:
acquire the RAR based on a random access radio network temporary identity (RA-RNTI) for the RAR, wherein 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.
