Classification: CPC H | IPC H

Claim 5:
6. The method according to claim 4, wherein allocating, by the network device to the terminal device based on the quantity of cells, the transmission resource for transmitting the SRS in the cell to which the terminal device belongs comprises:
dividing, by the network device, a physical cell identifier (PCI) of the cell to which the terminal device belongs by the quantity of cells to obtain a remainder;
determining, by the network device based on the remainder, the cell to which the terminal device belongs as a target cell, wherein the target cell is a fourth cell or a fifth cell, wherein the fourth cell is a cell for which the remainder obtained by dividing the PCI by the quantity of cells is a first value, wherein the fifth cell is a cell for which the remainder obtained by dividing the PCI by the quantity of cells is a second value, wherein a transmission resource for transmitting an SRS in the fourth cell is a fifth sub-band or a sixth sub-band, wherein a transmission resource for transmitting an SRS in the fifth cell is a seventh sub-band or an eighth sub-band, wherein the fifth sub-band and the seventh sub-band are obtained based on a quantity of frequency domain resources comprised in a system bandwidth, wherein a frequency of the fifth sub-band is less than a frequency of the seventh sub-band, wherein the sixth sub-band is a part of the fifth sub-band, and wherein the eighth sub-band is a part of the seventh sub-band; and
allocating, by the network device to the terminal device, the transmission resource for transmitting the SRS in the target cell.
