Claim 10:
11. A network 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 input interface is configured to receive a random access request sent by a terminal 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 output interface is configured to send a random access response (RAR) in response to the random access request,
wherein the output interface is further configured to:
send the RAR based on a random access radio network temporary identity (RA-RNTI) required to send 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.
