Abstract

The embodiment of the invention provides a silent period synchronization method and a device. The method comprises the following steps of: acquiring silent period configuration of a public control channel coverage region, wherein same perception frequency points in the silent period configuration are with the same silent period configuration; and broadcasting silent period configuration information to the public control channel coverage region according to the silent period configuration, wherein the silent period configuration information is used for ensuring equipment which is with the same perception frequency points in the public control channel coverage region to carry out the same silent period configuration, and the silent period configuration information comprises the perception frequency points, the silent period cycle of the perception frequency points, an silent period offset and a silent period duration time. According to the embodiment of the invention, the problem of silent period non-synchronization among the traditional cognitive cells is solved and the frequency spectrum utilization rate is increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of pass technology, and in particular, to a method and device for synchronizing a silent period. Background technique [0002] Cognitive Radio (CR for short) is the most promising technology to solve the current shortage of spectrum resources. By sensing the wireless spectrum environment, cognitive radio can perceive unoccupied frequency bands that appear anytime and anywhere, and dynamically access these frequency bands without interfering with the main user (the original fixedly allocated frequency user), so as to achieve seamless use and improve Spectrum utilization. [0003] When a cognitive device performs spectrum sensing, it usually adopts a periodic sensing scheme. Among them, the perceived frequency point, perceived duration, and perceived cycle are called silent period configurations. Cognitive devices with the same sensing frequency point have the same silent period configuratio...
