Embodiment 1

[0166] This preferred embodiment describes the process of feeding back the load level of the virtual second-type nodes.

[0167] Such as Figure 9 As shown, in a cluster in a community, there are four second-type nodes, namely node 1, node 2, node 3, and node 4, which are combined to form a virtual second-type node. Node i sends the load level Fi when node i communicates with other nodes to the base station of the sending network, and the base station receives the load level Fi, where i=1, 2, 3, 4. And F1, F2, F3, F4 are processed to obtain the load level F corresponding to the virtual second-type node. This processing includes but is not limited to taking the minimum value of F1, F2, F3, and F4 as F, or taking F1, The maximum value of F2, F3, F4 is F, or the average value of F1, F2, F3, F4 is F.

[0168] The base station compares the load levels F of multiple different virtual second-type nodes. Select the virtual second-type node with the smallest load level. If the load ...

Embodiment 2

[0170] This preferred embodiment describes the process of feeding back the load level of the virtual second-type nodes.

[0171] Such as Figure 9 As shown, in a cluster in a community, there are four second-type nodes, namely node 1, node 2, node 3, and node 4, which are combined to form a virtual second-type node. Node i sends the load level Fi when node i communicates with other nodes to an integrated node outside the four nodes, and the integrated node receives the load level Fi, where i=1, 2, 3, 4. And F1, F2, F3, F4 are processed to obtain the load level F corresponding to the virtual second-type node. This processing includes but is not limited to taking the minimum value of F1, F2, F3, and F4 as F, or taking F1, The maximum value of F2, F3, and F4 is F, or the average value of F1, F2, F3, and F4 is taken as F, and the integrated node sends the load level F to the base station.

[0172] The base station receives load levels F corresponding to multiple virtual second-t...

Embodiment 3

[0174] This preferred embodiment describes the process of feeding back the load level of the virtual second-type nodes.

[0175] Such as Figure 9 As shown, in a cluster in a community, there are four second-type nodes, namely node 1, node 2, node 3, and node 4, which are combined to form a virtual second-type node. Node i sends the load level Fi when node i communicates with other nodes to the first node 1. Here, node 1 is used as an integrated node, and other nodes are used as integrated nodes. The processing method is similar and will not be repeated here. Node 1 receives load class Fi, where i=2,3,4. Since node 1 knows the size of F1, it combines F2, F3, and F4 to obtain the load level F corresponding to the virtual second-type node. This processing includes but is not limited to taking the minimum value of F1, F2, F3, and F4 as F , or take the maximum value of F1, F2, F3, F4 as F, or take the average value of F1, F2, F3, F4 as F, and the integrated node sends the load l...

Abstract

Provided are a signalling transmission method and apparatus. The method comprises: sending channel metrics among K second-type nodes in virtual second-type nodes to first-type nodes, wherein K is a positive integer, and the channel metrics are used for characterizing the channel conditions among the K second-type nodes. By means of the technical solution provided by the present invention, the problem of a data transmission solution in the related art that second-type nodes are paired to form Mu-MIMO in the second-type nodes without virtualization or second-type nodes in other clusters is solved, and then a solution that a plurality of second-type nodes send channel metrics among nodes to first-type nodes is provided, thus enlarging the application range of MIMO technology.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a signaling transmission method and device. Background technique [0002] In wireless communication technology, when the first type of nodes, such as evolved base stations (eNB, eNode B), use multiple antennas to transmit data, they can use spatial multiplexing to increase the data transmission rate, that is, the first type of nodes use the same The time-frequency resource transmits different data at different antenna positions, and the second type of nodes, such as user equipment (UE, UserEquipment), also uses multiple antennas to receive data. In the case of a single user, the resources of all antennas are allocated to the same user, and this user exclusively occupies the physical resources allocated to the base station side within a transmission interval. This transmission method is called single-user multiple-input multiple-output (SU- MIMO, Single User Multiple-Input Mult...
