Embodiment 1
[0026] Such as Figure 4 As shown, it is a schematic diagram of the implementation process of implementing a SRS interference coordination method, including the following steps:
[0027] S401. Divide the Sounding reference signal resource into a preset number of clusters;
[0028] During specific implementation, the Sounding reference signal resources are first divided into N clusters, preferably, N≥3.
[0029] Specifically, the principles of clustering are as follows:
[0030] Step 1, respectively determining the number of clusters of the Sounding reference signal on the time-domain resource and the frequency-domain resource;
[0031] 1. Determine the number of clusters of the Sounding reference signal on the time domain resource
[0032] Preferably, the number N of clusters of the Sounding reference signal on the time domain resource can be determined according to the system time slot ratio 1 . Specifically, the number N of clusters of the Sounding reference signal on t...
Embodiment 2
[0046] It can be known from Embodiment 1 that as the number of clusters increases, the system gain becomes more obvious. However, after the Sounding Reference Signal resources are clustered, the number of Sounding Reference Signal resources that can be used by the same cell becomes smaller, and the number of users that can be supported is also reduced. will become less. In order to increase the system capacity, in the second embodiment, when the number of users to be supported by the cell increases, the initially determined number of Sounding reference signal resource clusters is dynamically adjusted to adjust the system capacity. For example, in the initial division, the Sounding reference signal resources are divided into 6 clusters, but as the number of users in the cell increases, the Sounding reference signal resources can be adjusted to 3 clusters to support more users. For specific implementation, please refer to Implementation Example 1 will not be repeated here. Ther...
Embodiment 3
[0052] Such as Figure 5 As shown, it is a schematic structural diagram of the SRS interference coordination device provided by the embodiment of the present invention, including:
[0053] A dividing unit 501, configured to divide Sounding reference signal resources into a preset number of clusters;
[0054] The allocating unit 502 is configured to allocate each Sounding reference signal resource cluster to different cells.
[0055] Specifically, the allocating unit 502 may be configured to configure different Sounding reference signal resource clusters for the same number of cells as the number of Sounding reference signal resource clusters, and indicate the Sounding reference signal resource clusters being configured by the mobile terminal in the cell The Sounding Reference Signal is sent on the included Sounding Reference Signal resource.
[0056] In specific implementation, the SRS interference coordination device may also include:
[0057] The first determining unit is...
