1. A communication method, performed by a network device, the method comprising:
sending indication information to a terminal, the indication information comprising a frequency band indicator corresponding to a frequency range, an uplink transmission shift identifier, and a cell reservation identifier, wherein a same frequency range is indicated by different frequency band indicators, wherein the cell reservation identifier indicates whether a cell is reserved,
the method further comprising the indication information instructing the terminal to perform cell-directed behaviors and to determine the following:
when the terminal does not support the frequency band indicator in the indication information, determine that the cell is barred, and
when the terminal supports the frequency band indicator in the indication information, determine whether to enable an uplink transmission shift as indicated by the uplink transmission shift identifier,
wherein the frequency band indicators comprise at least one of the following:
a first frequency band indicator, the first frequency band indicator representing that a system operates in the frequency range and the uplink transmission shift is 0 KHz;
a second frequency band indicator, the second frequency band indicator representing that the system operates in the frequency range and the uplink transmission shift is 7.5 kHz; or
a third frequency band indicator, the third frequency band indicator representing that the system operates in the frequency range and the uplink transmission shift is 7.5 kHz or 0 KHz.
