Abstract
A frequency hopping processing method and apparatus are disclosed, where user equipment receives frequency hopping information, which is sent by a network device, of an extended transmission time interval (TTI); and determines a frequency hopping area of the extended TTI according to the frequency hopping information of the extended TTI. The frequency hopping area of the extended TTI and a frequency hopping area of a normal TTI do not overlap in frequency, and during M-PUSCH frequency hopping of each extended TTI, the user equipment can hop into a corresponding M-PUSCH frequency hopping area according to a preset frequency hopping pattern, and does not hop into a PUSCH frequency hopping area, so that a resource conflict does not exist when M-PUSCH frequency hopping of an extended TTI and PUSCH frequency hopping of a 1 ms TTI are performed at the same time.
