Problems solved by technology

[0005] 1. It is not suitable for flexible power control between devices in the secondary system; specifically, the database is used as a global management node to manage all secondary user devices, and the increase of each secondary user device on each TVWS spectrum resource will trigger the database to perform TVWS The allocation of spectrum resources, and even the readjustment of the transmission parameters of devices in multiple secondary systems, will affect the stability of the system;
[0006] 2. The delay is uncontrollable; specifically, the database is an entity operated by the main system operator or a third party, and its processing delay is not controlled by the secondary system, so the entire reconfiguration process is difficult to meet the secondary system business continuity requirements

Embodiment 1

[0138] When there is no working secondary system on the target TVWS spectrum, the secondary system reconfiguration management node allocates the power determination scheme of the TVWS spectrum resource to a base station under it. In the scheme, the CCP is used as the reconfiguration management node for description. Detailed process such as Figure 4 As shown, it is described in detail below:

[0139] Step 401: base station BS 1 Initiate a TVWS spectrum resource application to the secondary system central control node (CCP);

[0140] Concrete, BS 1 Send its own location information, and related capabilities or resource requirements information, such as: supported operating frequency range of 470-560MHz, bandwidth of 5MHz, expected transmission power of 30dBm, etc., to the CCP.

[0141] Step 402: CCP sends TVWS spectrum resource request information to the database;

[0142] Step 403: The database feeds back the free spectrum resource information and the maximum interference v...

Embodiment 2

[0148] When there is a working secondary system on the target TVWS spectrum, the secondary system reconfiguration management node allocates the transmit power scheme of the spectrum to the subordinate base stations. In this embodiment, the secondary system reconfiguration management node initiates a resource request to the database together after a period of time for subordinate base station resource applications. The detailed process is as follows: Figure 5 As shown, it is described in detail below:

[0149] Step 501: base station BS 1 、BS 2 successively to the central control node CCP of the secondary system where it is located 1 Initiate TVWS spectrum resource application;

[0150] Specifically, each base station reports relevant information separately, so that the CCP 1 Appropriate resources can be allocated. BS 1 Put your own location information, and related capabilities or resource requirements information, such as: BS 1 The supported operating frequency range i...

Embodiment 3

[0161] When multiple secondary systems use the same TVWS spectrum resources at the same time, the database allocates the allowable interference value for the multiple secondary systems based on the secondary system attributes. The signaling process is as follows: Figure 6 As shown, it is described in detail below:

[0162] Step 601: base station BS 1 、BS 2 and BS 3 Reconfigure the management node CCP to the secondary system to which it belongs 1 、CCP 2 Send a spectrum resource request;

[0163] Specifically, each base station reports relevant information respectively, so that the CCP can allocate appropriate resources. BS 1 、BS 2 belongs to CCP 1 : BS 1 、BS 2 Send their respective location information, and related capabilities or resource requirements information, such as: supported operating frequency range of 470-560MHz, bandwidth of 5MHz, expected transmission power of 40dBm, etc. to the CCP 2 ;BS 3 Send your own location information, related capabilities or re...

Abstract

The invention discloses an interference allocation method, comprising: a reconfiguration management node of a secondary system acquires or receives idle spectrum resource information, and the total interference value information that the secondary system is allowed to generate on idle spectrum resources; The reconfiguration management node calculates transmit power for the secondary user equipment subordinate to the reconfiguration management node according to the total interference value information that the secondary system is allowed to generate. The invention also discloses an interference distribution system, a reconfiguration management node and a database at the same time. The invention can realize the secondary system to flexibly configure the transmission power between devices within the range of the allocated total interference quota, and the configuration time delay is controllable.

Description

technical field [0001] The present invention relates to cognitive radio technology in the field of wireless communication, in particular to a secondary system-based interference allocation method, system, database and reconfiguration management node. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, but the spectrum resources that radio services rely on are limited. Faced with the continuous increase in people's demand for bandwidth, spectrum resources are extremely tense. However, in the traditional fixed spectrum allocation mode, the utilization rate of spectrum resources is not high. In a sense, it is this spectrum allocation system that is fixedly allocated to the licensed system that has caused the extremely tight situation of spectrum resources. The cognitive radio technology breaks the fixed spectrum allocation system in the traditional sense, and dynamically allocates the spectrum...
