example 1
[0051] Example 1: A binary tree indicates the situation of resources.
[0052] Figure 6 is a schematic diagram of Example 1 according to an embodiment of the present invention, such as Figure 6 As shown, it is assumed that resources are divided into 8 basic units (RB1, RB2, . . . , RB8), and a binary tree is constructed with 4 layers in total.
[0053] In the first step, suppose P 1 , P 2 , P 3 , P 4 Corresponding to the use probability of each layer of nodes, the restriction is 8*P 1 +4*P 2 +2*P 3 +P 4 = 1;
[0054] In the second step, set P 1 =0.08 / 8,P 2 =0.8 / 4,P 3 =0.119 / 2,P 4 = 0.001, the situation of resource indication is as follows Figure 6 shown;
[0055] The third step is to perform Huffman coding on each node to form a codebook, and the results are shown in Table 1:

example 2
[0060] Example 2: An Island tree indicates the resource situation.
[0061] Figure 7 is a schematic diagram of Example 2 according to an embodiment of the present invention, such as Figure 7 As shown, it is assumed that resources are divided into six basic units (RB1, RB2, ..., RB6), and an Island tree is constructed.
[0062] In the first step, suppose P 1 , P 2 , P 3 , P 4 , P 5 , P 6 Corresponding to the use probability of each layer of nodes, the restriction is 6*P 1 +5*P 2 +4*P 3 +3*P 4 +2*P 5 +P 6 = 1;
[0063] In the second step, set P 1 =0.006 / 6,P 2 =0.04 / 5,P 3 =0.6 / 4,P 4 =0.3 / 3,P 5 =0.052 / 2, P 6 =0.002 / 1, namely P 1 =0.001,P 2 =0.008,P 3 =0.15,P 4 =0.1,P 5 =0.026,P 6 =0.002, the indication of resources is as follows Figure 7 shown;
[0064] The third step is to perform Huffman coding on each node to form a codebook, and the results are shown in Table 2:

example 3
[0069] Example 3: A hybrid tree indicates the situation of resources.
[0070] Figure 8 is a schematic diagram of Example 3 according to an embodiment of the present invention, such as Figure 8 As shown, it is assumed that resources are divided into 12 basic units (RB1, RB2, . . . , RB12), and a hybrid tree is constructed. Assume that the lower 4-layer nodes are organized in the Island tree, that is, the lower 4-layer nodes are dual-parent nodes. Nodes above these levels take the form of a binary tree. The tree has 8 layers.
[0071] In the first step, suppose P 1 , P 2 , P 3 , P 4 , P 5 , P 6 , P 7 , P 8 Corresponding to the use probability of each layer of nodes, the restriction is 12*P 1 +11*P 2 +10*P 3 +9*P 4 +8*P 5 +4*P 6 +2*P 7 +P 8 = 1;
[0072] The second step is to set P 1 =0.02 / 12, P 2 =0.043 / 11, P 3 =0.6 / 10, P 4 =0.3 / 9, P 5 =0.02 / 8,P 6 =0.01 / 4,P 7 =0.006 / 2,P 8 =0.001, the indication of resources is as follows Figure 8 shown;
