Description

Technical Field The present invention relates to the technical field of communication processing, in particular to a resource indication method, user equipment, a network device and a computer storage medium. Background In an existing LTE system, granularity of resource allocation in frequency domain is a resource block group (RBG). The number of resource blocks (RB) contained in an RBG, namely an RBG size, is related to a system bandwidth, as shown in Table 1. Table 1System Bandwidth RangeRBG Size≤10111-26227-63364-1104 In 5th generation (5G) new radio (NR) standard, it has been determined that the RBG size will be related to the size of a bandwidth part (BWP) of a terminal, but not related to the size of the system bandwidth. However, in the prior art, a mapping relation between the RBG size and the size of the bandwidth part is not specified. If different BWP sizes respectively correspond to different RBG sizes, better scheduling flexibility can be obtained. However, as different terminals may have different BWP sizes, multiple scheduling granularities need to be adopted simultaneously in a cell, which results in high complexity of scheduling of a base station. If a same RBG size is adopted for different RBG sizes, a scheduler of the base station can be simplified, but the scheduling flexibility will be greatly limited.
