The disclosure provides a method and device for allocating a resource location with a frequency hopping function. The method includes: an uplink bandwidth of a Long Term Evolution (LTE) communication system is acquired; it is determined whether frequency hopping information needs to be allocated to uplink continuous frequency-domain resource location information in a multi-antenna port transmission mode, and when the frequency hopping information needs to be allocated, a length of a resource location and frequency hopping bit indicator and a length of frequency-domain resource location information are obtained according to the uplink bandwidth; a difference Value_D between the length of the resource location and frequency hopping bit indicator and the length of the frequency-domain resource location information is calculated; and frequency hopping information is allocated to the frequency-domain resource location information according to the difference Value_D. With the technical solution of the disclosure, allocation of frequency-domain resource location information with a frequency hopping function in a multi-port transmission mode can be supported.
