Embodiment 1

[0161] This preferred embodiment designs a new and more optimized resource allocation method from the perspectives of improving the flexibility of resource allocation, system performance, and application scenarios, so that the number of multiplexed nodes on the available frequency spectrum is as large as possible, and at the same time Properly increase the number of clusters to bring about frequency diversity gain. At the same time, some corresponding parameters are also introduced, which can reduce overhead and computational complexity to a certain extent.

[0162] The technical problem solved by this preferred embodiment is to provide a spectrum resource allocation method, which can realize that different UEs / UEgroups have their own resource allocation patterns, further reduce overhead and complexity and bring greater frequency diversity gain.

[0163] In order to solve the above problems, this preferred embodiment provides a spectrum resource allocation method,

Embodiment 2

[0234] image 3 It is a schematic diagram of resource allocation in the preferred embodiment of the present invention Figure 1 ,Such as image 3 shown. The resource allocation pattern is for a system bandwidth of 5MHz=25 RBs, and a cluster occurrence period T corresponding to the 5MHz system bandwidth is 6RB, or the number of clusters is 5. It should be noted that the corresponding relationship between the system bandwidth and the cycle of cluster appearance or the number of clusters can be specified in advance. In this preferred embodiment, the frequency-domain starting resource index of the default cluster is 0, but the frequency-domain starting resource index number of the cluster is not limited to the default value, and may be a resource in the middle of the frequency-domain resources.

[0235] The realization of the resource allocation pattern is described in detail by the allocation of RBs: Assume that the frequency-domain resource patterns allocated to user 1 or use...

Embodiment 3

[0253] Figure 4 It is a schematic diagram of resource allocation in the preferred embodiment of the present invention Figure II ,Such as Figure 4 As shown, the resource allocation pattern is aimed at a system bandwidth of 5MHz=25 RBs, and a cluster occurrence period T corresponding to the 5MHz system bandwidth is 8RB, or the number of clusters is 3. It should be noted that the corresponding relationship between the system bandwidth and the cycle of cluster appearance or the number of clusters can be specified in advance, and the size of each cluster is 2RB (that is, the size of one RBG). In this embodiment, the frequency-domain starting resource index of the default cluster is 0, but the frequency-domain starting resource index number of the cluster is not limited to the default value, and may be a middle resource in the frequency domain.

[0254] The realization of the resource allocation pattern is described in detail by the allocation of RBs: Assume that the frequency-...

Abstract

The invention provides a frequency spectrum resource allocation method and a frequency spectrum resource allocation device. The frequency spectrum resource allocation method comprises the steps of: determining a resource allocation pattern of nodes according to a preset parameter, wherein the preset parameter comprises at least one of the following: a frequency domain starting position or a frequency domain offset, a frequency domain ending position, lengths of continuously allocated resources or sizes of continuously allocated clusters, a number of clusters or a number of resource sets, a period T, a number of nodes multiplexed in a frequency domain resource, or a number of resources that can be allocated in a system; and acquiring a corresponding resource allocation indicator r by coding, in a preset coding manner, the resource allocation pattern determined according to at least one of the preset parameters, wherein the resource allocation indicator r is used for indicating information about a position of a resource allocated to UE. The frequency spectrum resource allocation method and the frequency spectrum resource allocation device solve the problems of poor flexibility of resource allocation, high overhead and low frequency diversity gain due to the limitation that only two clusters can be allocated to each user at most, and can allocate multiple clusters to each UE, thereby improving flexibility of resource allocation, decreasing overhead, and increasing frequency diversity gain.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a spectrum resource allocation method and device. Background technique [0002] In the long-term evolution (Long-Term Evolution, LTE for short) evolution process, in the LTE Rel-13 version, one of the important contents is that the LTE system can work on an unlicensed carrier. This technology will enable the LTE system to use existing unlicensed carriers, greatly enhance the potential spectrum resources of the LTE system, and enable the LTE system to obtain lower spectrum costs. [0003] In addition, according to the existing 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) standard on resource allocation, for discontinuous resource allocation, the number of clusters allocated to terminals is limited to no more than 2 This not only affects the flexibility of scheduling to a certain extent, but also reduces the gain brought by fre...
