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.

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.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and device. Background technique [0002] In wireless communication technology, when the first type of node, such as an evolved base station (E-UTRANNodeB, referred to as eNB) uses multiple antennas to transmit data, it can adopt multi-carrier transmission to increase the data transmission rate, that is, in the first type A node uses multiple carriers to transmit different data, and a second type of node, such as user equipment (User Equipment, UE for short), also uses multiple carriers to receive data. When multiple users have services, the base station can allocate different carrier resources to different users, and multiple users can be scheduled and receive data on different carriers; when only a single user has services, the base station can allocate all carriers For the same user, this user alone occupies the physical resources allocated to the...
