    • The disclosure provides a method for transmitting Cognitive Pilot Channel (CPC) information, a radio access method and system based on CPC information, wherein the method for transmitting CPC information includes: dividing a CPC into a primary CPC for transmitting primary CPC information and a secondary CPC for transmitting secondary CPC information; loading the primary CPC information periodically into fixed physical resources, and sending the primary CPC information to a user equipment; after a base station receives a preset triggering event, loading the secondary CPC information into variable physical resources, and sending the secondary CPC information to the user equipment. In the disclosure, the base station loads the primary CPC information into fixed physical resources of an RAT according to an RAT coverage condition, reducing the amount of information required to be delivered by fixed physical resources, decreasing occupation of fixed physical resources, speeding up radio access of the user equipment; and after receiving a triggering event, the base station loads the secondary CPC information into variable physical resources and sends the secondary CPC information to the user equipment, thus implementing optimization of a user network and radio resources.
    • 本发明提供了一种用于发送认知导频信道(CPC)信息的方法,基于CPC信息的无线接入方法和系统,其中,用于发送CPC信息的方法包括:将CPC划分为用于发送主要CPC信息的主CPC, 传输次要CPC信息的CPC; 将主要CPC信息周期性地加载到固定的物理资源中,并将主要CPC信息发送给用户设备; 在基站接收到预设触发事件之后,将次要CPC信息加载到可变物理资源中,并将次要CPC信息发送给用户设备。 在本公开中,基站根据RAT覆盖条件将主要CPC信息加载到RAT的固定物理资源中,减少固定物理资源需要传递的信息量,减少对固定物理资源的占用,加速无线电 访问用户设备; 接收到触发事件后,基站将次要CPC信息加载到可变物理资源中,并将次要CPC信息发送给用户设备,从而实现用户网络和无线资源的优化。

    • The disclosure discloses a method and an apparatus for transforming a working mode in a Cognitive Radio (CR) system, which are used for solving the technical problem that a subsystem maliciously occupies the spectrum resources which are temporarily unused by other system in a system adopting a CR technology. In the disclosure, a network side measures the demand degree of each cell on borrowed spectrum and sets a conditions of enabling and disabling the CR working mode to determine whether to perform working mode transformation on the cell and specify a network allocation method for a mobile terminal in a corresponding working mode, so as to coordinate the allocation of the spectrum resources, and avoid the abuse of the borrowed spectrum resources; the CR working mode of the cell with low demand degree is disabled by the network side; the borrowed spectrum resources of the cell are released; and therefore, more borrowed spectrum resources are available to the other cells having a higher demand degree on the borrowed spectrum, and the overall performance of the system is improved.
    • 本公开公开了一种用于转换认知无线电(CR)系统中的工作模式的方法和装置,其用于解决子系统恶意占用由系统中暂时未被其他系统使用的频谱资源的技术问题 CR技术。 在本公开中,网络侧测量借用频谱中的每个小区的需求度,并且设置使能和禁用CR工作模式的条件,以确定是否对小区执行工作模式转换,并为移动终端指定网络分配方法 在相应的工作模式下,协调频谱资源配置,避免滥用频谱资源; 低需求度的小区的CR工作模式被网络侧禁用; 电池的借用频谱资源被释放; 因此,对借用频谱具有较高需求度的其他小区可利用更多的借用频谱资源,提高系统的整体性能。
