[0027] There are a total of 30 RBs under the system bandwidth, and there are many options for sub-channel division. For example, it can be divided into 5 sub-channels, each sub-channel contains 6 RBs, or 6 sub-channels, each sub-channel contains 5 RBs; 3 sub-channels, each sub-channel contains 10 RBs. RBs or 10 subchannels each containing 3 RBs, etc. To divide several sub-channels specifically, conditions such as the total number of RBs, the number of sub-carriers contained in RBs, and signaling overhead need to be considered comprehensively. Here, the division of 4 sub-channels includes 8 RBs, and the last sub-channel includes 6 RBs as an example for illustration. The first 4 bits of the resource allocation signaling are "sub-channel selection indication bitmap", and the last 8 bits are "sub-channel RB selection indication bitmap", 12 bits in total. If each bit of the resource allocation signaling indicates the selection of one RB, 30 bits of signaling overhead are required,...
