Problems solved by technology

Typically, with the continuous improvement of people's daily communication needs, they are no longer satisfied with simple voice and data communication, and the proportion of video streaming services in people's communication life continues to increase, which requires greater bandwidth as a support. International mobile phones (IMT, International Mobile Telecom) system presents an unprecedented spectrum tension, and for radio and television systems, spectrum resources largely have available space, such as some radio and television system spectrum in some areas and Unused; although some radio and television system spectrums have coverage in a certain area, they are not used at certain times, and the overall utilization rate is low
However, the fixed spectrum allocation method prevents the above-mentioned unused spectrum resources from being reused, for example, cannot be used by the IMT system

Embodiment 1

[0050] This embodiment provides a method for determining transmit power based on coexistence, such as figure 2 As shown, including the following operations:

[0051] The database receives the coexistence requirement information of the secondary system user equipment sent by the SC, and determines the available frequency of the secondary system user equipment that initiates the spectrum resource application and the maximum transmission power limit of each available frequency according to the coexistence requirement information.

[0052] In the above method, before the database receives the coexistence requirement information of the secondary system user equipment sent by the SC, after the SC receives the spectrum resource application initiated by the secondary system user Analyzing and determining the coexistence requirement information of the secondary system user equipment that initiates the spectrum resource application, and then sending the determined coexistence requireme...

Embodiment 2

[0210] The technical solution of this application involves three logical entities: database (DB, Geo-location Database), spectrum coordinator (SC, Spectrum Controller), and secondary system user equipment (WSD, White Space Device). The specific functions are described as follows:

[0211] WSD: Initiate an application for idle spectrum resources, receive an operational parameter list (operational parameter), and select and determine its own operational parameters according to the list.

[0212] SC: Receive the free spectrum resource application sent by WSD, evaluate the coexistence requirements between WSDs that need to be met when WSD uses free spectrum resources, and send the free spectrum resource application and coexistence requirement information to the database; receive the free spectrum list generated by DB . Optionally, the SC may also perform inter-WSD self-coexistence processing, and feed back to the WSD applying for resources.

[0213] DB: According to the free spec...

Embodiment 3

[0224] This embodiment provides a database that can implement the method in Embodiment 1 above, which at least includes the following two units.

[0225] The first unit receives the coexistence requirement information sent by the spectrum coordinator (SC);

[0226] The second unit determines, according to the coexistence requirement information, the available frequencies of the secondary system user equipment that initiates the spectrum resource application and the maximum transmit power limit of each available frequency.

[0227] The above-mentioned second unit selects the spectrum that is not used by the primary system user equipment at the location of the secondary system user equipment and satisfies the coexistence requirement information as the available spectrum of the secondary system user equipment, and based on the primary system The user equipment protection principle, the propagation model, and the secondary system user equipment parameters respectively calculate th...

Abstract

A coexistence-based transmit power determining method, a spectrum coordinator (SC), and a database. The transmit power determining method comprises: the database receiving coexistence demand information of a white space device (WSD) sent by the SC; and the database determining, according to the coexistence demand information, usable frequencies of the WSD and a maximum transmit power limit of each usable frequency.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular, to a cognitive radio technology and a method for determining transmission power of a secondary system user equipment. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, and the spectrum resources on which radio services rely are limited. Facing the continuous increase in people's demand for bandwidth, spectrum resources are extremely tense; and On the other hand, under 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 assigned to the authorized 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 between ...
