[0117] In some embodiments, the terminal 101 sends the SRS to the network device 102 at at least one frequency hopping point.

[0118] In some embodiments, the at least one frequency hopping point is used to determine the Rx-Tx time difference of the terminal 101 .

[0119] The sending and receiving time difference of the terminal refers to the time difference between the terminal receiving the positioning reference signal PRS and sending the sounding reference signal SRS, and the sending and receiving time difference can be used for positioning measurement of the terminal.

[0120] In some embodiments, the terminal 101 supports the at least one frequency hopping point being outside an active bandwidth part (Bandwidth Part, BWP) of the uplink (UL) of the terminal 101 .

[0121] In some embodiments, the parameter set (numerology) of the SRS supported by the terminal 101 on each frequency hopping point in the at least one frequency hopping point is different from the uplink active BWP (UL active BWP).

[0129] In some embodiments, the capability information is used to indicate that the parameter set of the SRS supported by the terminal 101 on each of the at least one frequency hopping point is different from the BWP activated in the terminal uplink.

[0130] In some embodiments, the name of the above-mentioned capability information is not limited, and it may be, for example, "different parameter sets for SRS transmission frequency hopping", "PRS measurement based on SRS transmission frequency hopping has different parameter sets (PRSMeasWithSRSTXFH-DiffNumerology)", "different parameter sets for partial bandwidth (bwp-DiffNumerology)", "different parameter sets for partial bandwidth", "partial bandwidth configuration capability", etc.

[0132] The SRS on the transmission frequency hopping point may be outside the UL activated BWP of the terminal, and the parameter set corresponding to the SRS on the transmission frequency hopping point is different from that of the SRS in the UL activated BWP.

[0133] In some embodiments, the capability information may not be sent to the network device 102 , because the protocol stipulates that the terminal 101 supports the capability, or the terminal 101 supports the capability by default, and so on.
