Description

ABS式样估计方法、装置及用户设备ABS style estimation method, device and user equipment

技术领域technical field

本发明涉及无线通信技术领域，尤其涉及一种ABS式样估计方法、装置及用户设备。The present invention relates to the field of wireless communication technologies, and in particular, to an ABS pattern estimation method, device and user equipment.

背景技术Background technique

LTE(Long Term Evolution，长期演进)系统在R10以后的版本引入了eICIC/FeICIC(Enhanced Inter-cell Interference Coordination/Further Enhanced Inter-cell Interference Coordination，增强型小区干扰协调/未来增强型小区干扰协调)技术。eICIC在时域中引入了ABS(Almost Blank Subframe，几乎空白子帧)的概念，来实现时域的协调处理，降低小区间的干扰程度。ABS只包含一些必要的信号，且发射功率比较低，eICIC通过在干扰小区中配置ABS，而在被干扰小区中使用这些ABS，从而避免了小区间的干扰问题。The LTE (Long Term Evolution, Long Term Evolution) system introduced eICIC/FeICIC (Enhanced Inter-cell Interference Coordination/Further Enhanced Inter-cell Interference Coordination, Enhanced Inter-cell Interference Coordination/Future Enhanced Inter-cell Interference Coordination) technology in versions after R10 . eICIC introduces the concept of ABS (Almost Blank Subframe, almost blank subframe) in the time domain to realize coordination processing in the time domain and reduce the degree of interference between cells. ABS only contains some necessary signals, and the transmit power is relatively low, eICIC configures ABS in the interfering cell and uses these ABS in the interfered cell, thereby avoiding the problem of inter-cell interference.

通过配置ABS子帧，下行通道的无线帧包含ABS和nonABS(Non-Almost BlankSubframe，非几乎空白子帧)。在服务小区，终端用户经历的干扰会随着干扰基站的ABS式样起伏变化，在eICIC/FeICIC场景中，终端用户不能通过信令消息直接获得邻小区的ABS式样，因此需要检测出干扰基站的ABS式样，根据ABS和nonABS的配置信息选取相应的检测参数和检测算法来避免干扰，以提高系统性能。By configuring the ABS subframe, the radio frame of the downlink channel includes ABS and non-ABS (Non-Almost Blank Subframe, non-almost blank subframe). In the serving cell, the interference experienced by the terminal user will fluctuate with the ABS pattern of the interfering base station. In the eICIC/FeICIC scenario, the terminal user cannot directly obtain the ABS pattern of the neighboring cell through signaling messages, so it is necessary to detect the ABS of the interfering base station. According to the configuration information of ABS and nonABS, the corresponding detection parameters and detection algorithms are selected to avoid interference and improve system performance.

现有技术中检测ABS式样的方法使用比较多的是将系统配置的小区测量信息和CSI(Channel State Information，信道状态信息)作为干扰基站的ABS式样，或者利用较多的子帧信息来检测ABS式样。The methods for detecting ABS patterns in the prior art are to use the cell measurement information and CSI (Channel State Information, channel state information) configured by the system as the ABS patterns of the interfering base station, or use more subframe information to detect ABSs. style.

在实现本发明的过程中，发明人发现现有技术中至少存在如下技术问题：In the process of realizing the present invention, the inventor found that there are at least the following technical problems in the prior art:

系统配置的小区测量信息和CSI测量信息只是ABS式样的一部分，不能代表ABS式样的整个周期；而如果利用较多的子帧来检测ABS式样，一旦ABS式样有变化，就会需要更多的子帧检测出ABS式样，并且一旦ABS式样中某一子帧的nonABS/ABS状态错误，整个ABS式样都要重新检测。The cell measurement information and CSI measurement information configured by the system are only a part of the ABS pattern and cannot represent the entire cycle of the ABS pattern. If more subframes are used to detect the ABS pattern, once the ABS pattern changes, more subframes will be required. The frame detects the ABS pattern, and once the nonABS/ABS state of a subframe in the ABS pattern is wrong, the entire ABS pattern must be re-detected.
