摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a resource scheduling method, which includes: determining, by a UE, a resource allocation indicating way in DCI of a first type search space and a resource allocation indicating way in DCI of a second type search space, wherein the resource allocation indicating way comprises an allocation unit of a UE frequency resource and a bandwidth and a location of all frequency resources available for UE frequency resource allocation; in the first type search space and the second type search space, performing, by the UE, blind detection for PDCCH/EPDCCH on the bandwidth and the location of all the frequency resources available for the UE frequency resource allocation in the corresponding resource allocation indicating way according to the allocation unit of the UE frequency resource in the corresponding resource allocation indicating way, determining a bandwidth and a location of an uplink resource and/or a downlink resource actually allocated for the UE. According to the present disclosure, in a condition that the UE cannot support the entire system bandwidth, an uplink resource and a downlink resource allocated by a base station can still be appropriately determined.
