Problems solved by technology

[0007] However, in the prior art, the mapping relationship between the RBG size and the bandwidth part size is not clear
If different BWP sizes correspond to different RBG sizes, better scheduling flexibility can be obtained, but since different terminals can have different BWP sizes, multiple scheduling granularities need to be used in a cell at the same time, which will result in higher base station scheduling complexity
If the same RBG size is used for different RBG sizes, the base station scheduler can be simplified, but the scheduling flexibility will be greatly limited

Embodiment 1

[0035] An embodiment of the present invention provides a resource indication method, which is applied to user equipment, such as figure 1 shown, including:

[0036] Step 101: select a target mapping relationship from at least two candidate mapping relationships;

[0037] Step 102: Determine the size of the target resource block group according to the size range of the bandwidth part in the target mapping relationship;

[0038] Step 103: Allocate frequency domain resources according to the size of the target resource block group and the first control information sent by the network side;

[0039] Wherein, the at least two candidate mapping relationships include at least a first mapping relationship and a second mapping relationship; in the first mapping relationship, each group of bandwidth part size ranges maps different resource block group sizes; the second mapping In the relationship, at least two sets of bandwidth part size ranges can be mapped to the same resource bloc...

Embodiment 2

[0065] An embodiment of the present invention provides a resource indication method, applied to a network device, including:

[0066] sending first control information to the user equipment, where the first control information is used to instruct the user equipment to allocate frequency domain resources according to the size of the target resource block group in the target mapping relationship;

[0067] The target mapping relationship is one of at least two candidate mapping relationships, and the at least two candidate mapping relationships include at least a first mapping relationship and a second mapping relationship; in the first mapping relationship, each group of bandwidth parts The size ranges map different resource block group sizes; in the second mapping relationship, at least two sets of bandwidth partial size ranges can be mapped to the same resource block group size.

[0068] The network device provided in this embodiment may be a base station on the network side, ...
