Abstract

The invention discloses a method for realizing effective utilization of spectrum holes based on available cellular communication signaling, which is characterized in that the available cellular communication mode and the cognitive communication mode adopt a same clock source, a user terminal keeps the synchronization of the carrier frequency and the frame timing of the cognitive communication mode by locking on the carrier frequency and the frame timing of the available cellular communication mode. Signaling messages for allocating the frequency point, the bandwidth and the perceived spectrum holes of the cognitive communication mode are added in the available cellular communication signaling. A base station determines the cognitive manner including working parameters of the frequency, the bandwidth and the perceived spectrum holes based on the perception result, and notifies a terminal in time via the signaling of the available cellular communication mode. The terminal allocates the cognitive communication mode thereof according to the effective time. The perceived spectrum results interact among base stations, and the user terminal transmits and reports the perceived spectrum information to the base stations via the signaling of the available cellular communication mode. The method can effectively adopt cognitive radio technology in the radio cellular communication system, take full use of spectrum holes resource, and reduce possible conflicts with authorized users.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, relates to wireless cellular communication and cognitive radio technology, and in particular to a method for effectively utilizing spectrum holes based on existing cellular communication signaling transmission. Background technique

[0002] The rapid development of wireless communication technology makes the limited spectrum resources more and more tense. The concept of cognitive radio (Cognitive Radio) proposed by IEEE Personal Communications in 1999, its core idea is to enable wireless communication devices to have the ability to discover and reasonably use "spectrum holes", so that Cognitive wireless communication devices can operate in authorized frequency bands in an "opportunistic" manner. The spectrum resources that can be utilized in the air domain, time domain and frequency domain are called "spectrum holes". The current research on cognitive wireless technology focuses ...
