Abstract

The invention discloses a method, a device and a communication system for implementing frequency hopping. Acquiring a total bandwidth of uplink resources and a bandwidth reserved for a PUCCH channel, the embodiment of the invention uses the difference of the total bandwidth of the uplink resources and the bandwidth reserved for the PUCCH channel as a bandwidth distributed to a PUSCH channel so that the idle bandwidth of the PUCCH channel, i.e. idle RB, can be fully utilized. Compared with the prior art, adopting the scheme can improve frequency hopping gain and utilization rate of the frequency bandwidth resources.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a frequency hopping implementation method, device and communication system. Background technique [0002] Currently, in a Long Term Evolution (LTE, Long Term Evolution) system, uplink resources are generally allocated in a localized frequency hopping (Localized FH, Localized Frequency Hopping) manner. The so-called Localized FH method refers to the data transmission that the user equipment (UE, User Equipment, hereinafter referred to as the terminal) only occupies a certain continuous frequency band at a certain moment, but jumps to another frequency band at the next moment. Way. According to different frequencies of frequency hopping, it can be divided into frequency hopping within a transmission time interval (TTI, Transform Time Interval) (Intra-TTI FH) and frequency hopping between TTIs (Inter-TTI FH); wherein, frequency hopping between TTIs is every Frequency...
