Abstract

The invention discloses a data transmission method and device. The method comprises the following steps: N second type nodes form third type nodes, and N is a positive integer greater than or equal to 2; data transmission is conducted in a network formed by the second type nodes, the third type nodes and fist type nodes. The data transmission method and device help solve a problem that carrier wave sharing among a plurality of nodes cannot be realized, carrier wave sharing among devices can be realized, resource waste can be reduced, and overall network transmission performance is improved.

Example Embodiment

[0121] Example 1:
[0122] Figure 7 Is a schematic diagram of a data transmission method according to an embodiment of the present invention, such as Figure 7 As shown, N (N=4) second-type nodes are formed into a third-type virtual node with multi-carrier capability. The above-mentioned N second-type nodes have M1, M2, ... M N Carrier capability, the above-mentioned third type of node has equal to M = M1 + M2 +... N A carrier capable node.
[0123] Optionally, the above-mentioned third type of virtual node is an aggregation node, and different nodes are aggregated in the unit of component carrier, thereby forming a composite node, such as: enhanced carrier capability, enhanced processing capability, enhanced connection scheme, etc. .

Example Embodiment

[0124] Example 2:
[0125] Figure 8 Is a schematic diagram (1) of a data transmission method according to an embodiment of the present invention, such as Figure 8 As shown, N (N=2) second-type nodes form a third-type node with multi-carrier capability. The second-type node 1 and the second-type node 2 each have the capability of 1 carrier (M1=M2 =1), the second type node 1 and the second type node 2 receive the data sent from the first type node on M (M=2) carriers; the second type node 1 will receive the first type The data of the node is then forwarded to the second-type node 2 in the third-type node.
[0126] The data transmission between the second type node 1 and the second type node 2 can be transmitted through wireless communication or wired communication.

Example Embodiment

[0127] Example 3:
[0128] Picture 9 Is a schematic diagram (2) of a data transmission method according to an embodiment of the present invention, such as Picture 9 As shown, N (N=2) second-type nodes are formed into a third-type node with multi-carrier capability, where the second-type node 2 with the new type of carrier capability receives from one or more first-type nodes Send data on a new type of carrier; the second type node 2 forwards the received data of the first type node to the second type node 1 in the third type node.
[0129] The data transmission between the second type node 1 and the second type node 2 can be transmitted through wireless communication or wired communication.
