NR PDCCH RESOURCE ALLOCATION METHOD AND APPARATUS UNDER SPECTRUM SHARING

Disclosed are an NR PDCCH resource allocation method and apparatus under spectrum sharing, which are used for solving the problem of a resource conflict. The method comprises: a network side configuring a Coreset resource associated with an NR UE-specific search space to occupy the full bandwidth in a frequency domain, to occupy, in a time domain, any consecutive N symbols excluding the first three symbols in a downlink slot, and not to conflict with specified symbols, wherein the specified symbols include symbols occupied by common control channels and demodulation signals in an NR system and an LTE system. In this way, by means of sharing a spectrum, a network side can accurately allocate, in a downlink slot and by means of dynamic adjustment, a resource, which is occupied by an NR PDCCH, to a target NR UE, thereby effectively reducing the probability of an allocation conflict occurring between the resource occupied by the NR PDCCH and a resource occupied by an LTE PDCCH, and also better improving the spect
