Embodiment 1

[0104] Embodiment 1: Embodiment 1 is the optimal distribution scheme of the present invention, and the present embodiment comprises the following steps:

[0105] Step 1. Set the user minimum data transmission rate R min , user available power upper limit Spectrum Detection Threshold and sub-channel interference preset thresholds

[0106] Step 2: The BS / AP node in the multi-genre heterogeneous system allocates the original sub-channel for each user, and uses the spectrum detection threshold and sub-channel interference preset thresholds Detecting the spectrum hole subchannels in the multi-genre heterogeneous system again, the BS / AP node assigns the detected spectrum hole subchannels to each user;

[0107] Roughly speaking, Step 2 includes three parts. The first is the raw resource allocation stage. The multi-generity heterogeneous network system allocates the original sub-channels of BSs / APs nodes to their respective users, and at the same time, they calculate the c...

Embodiment 2

[0202] Considering the complex calculation process of the optimal allocation scheme given in Embodiment 1, this embodiment further provides a suboptimal framework for it, so as to reduce system overhead and calculation complexity. This is more in line with the needs of the actual system.

[0203] The allocation result of the optimal strategy proposed in Embodiment 1 must be updated every time channel state information (channel state information, CSI) changes. This results in a large amount of data transmission, multiple spectrum detections and high system overhead. In order to reduce the overhead and reduce the computational complexity, the following embodiment provides a three-step suboptimal allocation strategy for Step 2 of Embodiment 1. The first step of step 2 is the original resource allocation, which only needs to be performed once at the beginning of the entire allocation process. The basis of the original resource allocation in this step is not the instantaneous cha...

Abstract

In order to solve the problem that through adoption of an existing allocation method, limited resources cannot be sufficiently utilized and high system throughput and energy efficiency cannot be acquired, the invention discloses a cognition-based original resource and detected hole resource joint allocation method and belongs to the technical field of information and communication. The method comprises the steps that the user minimum data transmission rate R<min>, a user available power upper limit P<max><T>, a spectrum detection threshold I1 and a sub-channel interference preset thresholdI2 are set; a BS / AP (Base Station / Access point) node in a multi-attribute heterogeneous system allocates original sub-channels to each user and detects spectrum hole sub-channels in the multi-attribute heterogeneous system through utilization of the spectrum detection threshold I1and the sub-channel interference preset threshold I2, and the BS / AP node allocates the detected spectrum hole sub-channels to each user; and when allocation is carried out, the fact that R<m> is greater than or equal to the R<min> and P<m> is smaller than or equal to P<max><T> is taken as a limitation condition, and moreover, through utilization of a Lagrange duality method, an optimum user original sub-channel allocation result and an optimum spectrum hole sub-channel allocation result are acquired,wherein the R<m> indicates a data transmission total rate of a user m, and the P<m> indicates the total power consumed by the user m.

Description

technical field [0001] The invention relates to a method for joint allocation of bandwidth resources, in particular to a method for joint allocation of original resources and detected hole resources based on cognition, and belongs to the technical field of information and communication. Background technique [0002] In the last ten years, researchers in the radio field have been looking for ways to achieve a thousand-fold increase in multimedia application devices. A multi-genre network framework is considered as a potential solution that can help achieve this goal. User equipment with multi-attribute capabilities can simultaneously transmit data with different base stations (base stations, BSs) and access points (access points, APs) in heterogeneous wireless networks, so as to integrate and utilize the bandwidth resources of these BSs / APs , to achieve the purpose of increasing the data transmission rate. Moreover, compared with single-ownership network access, this kind o...
