TECHNICAL FIELD

The disclosure relates to the technical field of information processing, and particularly, to a method for interference processing, a terminal device, a network device and a computer storage medium.

BACKGROUND

At present, with pursuit of people for rate, delay, high-speed mobility and efficiency and diversification and complication of services in the future life, the international standard organization 3rd Generation Partnership Project (3GPP) has started researching and developing 5th-Generation (5G). During early deployment of New Radio (NR), it is difficult to implement complete NR coverage, and thus typical network coverage includes wide area Long Term Evolution (LTE) coverage and an NR island coverage mode. Moreover, LTE is mostly deployed below 6 GHz and there are few spectrums for 5G below 6 GHz, so researches on application of spectrums above 6 GHz for NR are required. However, a high frequency band is limited in coverage and fast in signal fading. Meanwhile, for protecting early LTE investment of mobile operating companies, a working mode of tight interworking between LTE and NR is proposed.

For supporting LTE-NR interworking in 5G, when a terminal simultaneously operates at two or more carriers in different frequency bands, uplink signals of these carriers may interfere with downlink received signals of some carriers.
