Technical field
The present invention relates to communication technical field, more particularly to a kind of method to set up of frequency domain resource, device and base station.
Background technology
5G NR (New Radio Access Technology, access technology of newly eating dishes without rice or wine) support there is different TTI
The physical signalling of (Transmission Time Interval, Transmission Time Interval) and frame structure (Frame Structure)
In an identical BWP (Band Width Part, frequency domain wideband portions) simultaneous transmission.For example, in identical BWP, it is short
TTI URLLC (Ultra Reliable and Low Latency Communication, super reliable, low time delay communication) thing
EMBB (enhanced Mobile Broad Band, the mobile broadband of enhancing) physical signalling of reason signal and long TTI accounts for respectively
With different frequency domain bandwidths, and carry out the dynamic frequency domain resource multiplexing of signal in a BWP or semi-static frequency domain resource is answered
With.
However, the short TTI of simultaneous transmission URLLC physical signallings and long TTI eMBB physical signallings hold in same BWP
Some interference problems are easily caused, such as：The downlink signal of short TTI frame structures from loopback signal to long in nearby frequency bands
The strong jamming of the uplink receiving signal of TTI frame structures；Again such as：The downlink signal of long TTI frame structures from loopback signal
Strong jamming to the uplink receiving signal of short TTI frame structures in nearby frequency bands.For the uplink receiving signal of base station, due to interference
Transmission signal of the signal from base station itself from loopback signal or leakage signal, so the intensity of interference signal is generally very
Greatly, and interference signal feature generally with surrounding environment dynamic change, therefore, be both difficult to accurately to estimate that this was dry in systems in practice
Signal is disturbed, is difficult to dynamic again and tracks the interference signal.So up-downgoing interference can seriously reduce the performance of uplink receiving signal.
The content of the invention
In view of the foregoing, it is necessary to a kind of method to set up of frequency domain resource, device and base station are provided, can be reduced same
Up-downgoing interference in individual BWP during different TTI physical signalling multiplexing, meanwhile, the performance of raising base station side uplink receiving signal.
A kind of method to set up of frequency domain resource, methods described include：
