Problems solved by technology

[0003] However, the simultaneous transmission of short TTI URLLC physical signals and long TTI eMBB physical signals in the same BWP is likely to cause some interference problems, such as: the self-loopback signal of the downlink transmission signal with a short TTI frame structure interferes with the long TTI on the adjacent frequency band Strong interference of uplink received signals with frame structure; another example: strong interference of self-loopback signals of downlink transmit signals with long TTI frame structure to uplink received signals with short TTI frame structure on adjacent frequency bands
For the uplink received signal of the base station, since the interference signal comes from the self-loopback signal or leakage signal of the base station's own transmission signal, the strength of the interference signal is usually very large, and the characteristics of the interference signal usually change dynamically with the surrounding environment. Therefore, in practice It is difficult to accurately estimate the interference signal in the system, and it is also difficult to dynamically track the interference signal
Therefore, uplink and downlink interference will seriously degrade the performance of uplink received signals

Abstract

A method for setting frequency domain resources, the method comprising: in the same frequency domain broadband part BWP, judging whether the first frequency domain resource allocated for physical signal transmission of a short transmission time interval TTI in the BWP includes protection Bandwidth; wherein, in the BWP, the physical signal of the short TTI and the physical signal of the long TTI respectively occupy different frequency domain resources of the BWP; If a frequency domain resource includes a guard bandwidth, a second frequency domain resource is set on the first frequency domain resource as the guard bandwidth for the short TTI. The present invention also provides a frequency domain resource setting device and a base station. The invention can reduce the uplink and downlink interference when the physical signals of different TTIs are multiplexed in the same BWP, and at the same time, improve the performance of uplink receiving signals at the base station side.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, device and base station for setting frequency domain resources. Background technique [0002] 5G NR (New Radio Access Technology, new air interface access technology) supports physical signals with different TTI (Transmission Time Interval, transmission time interval) and frame structure (Frame Structure) in the same BWP (Band Width Part, frequency domain broadband part) are transmitted simultaneously. For example, in the same BWP, URLLC (Ultra Reliable and Low Latency Communication) physical signals of short TTI and eMBB (enhanced Mobile Broad Band, enhanced mobile broadband) physical signals of long TTI occupy respectively Different frequency domain bandwidths, and perform dynamic frequency domain resource multiplexing or semi-static frequency domain resource multiplexing of signals within a BWP. [0003] However, the simultaneous transmission of sh...
