Translated fromChinese技术领域technical field
本发明涉及通信领域，具体而言，涉及一种上行功率的调整方法和装置。The present invention relates to the field of communications, and in particular, to a method and device for adjusting uplink power.
背景技术Background technique
在3GPP LTE(Long Term Evolution，长期演进)系统中，为了避免同频干扰问题和频繁切换造成的相关问题，LTE网络采用合并小区的方式来解决问题，即将几个物理小区ID不同的独立小区，合并为具有一个PCI(PCI，Physical Cell Identifier)的逻辑小区，合并后的逻辑小区也称之为超级小区(SuperCell)，原来独立的各个物理小区变成了超级小区的一个部分(CP,Cell Portion)。SuperCell中控制整个小区调度的CP为小区级主CP，而其他非调度CP为小区级辅CP。In the 3GPP LTE (Long Term Evolution) system, in order to avoid the problem of co-channel interference and related problems caused by frequent handovers, the LTE network adopts the method of merging cells to solve the problem, that is, several independent cells with different physical cell IDs, Merged into a logical cell with a PCI (PCI, Physical Cell Identifier), the merged logical cell is also called a super cell (SuperCell), the original independent physical cells become a part of the super cell (CP, Cell Portion ). The CP that controls the scheduling of the entire cell in the SuperCell is the cell-level primary CP, and other non-scheduling CPs are cell-level secondary CPs.
在实际网络覆盖中，经常采用微站(Micro Cell)放置在宏站(Macro Cell)覆盖范围内进行热点覆盖(Hot compensation),如图1所示。为了避免宏微基站之间的同频干扰，宏微小区覆盖采用小区合并模式形成一个宏微异构超级小区，其中Macro Cell和MicroCell分别称为宏微异构超级小区的一个CP(如Macro CP0和Micro CP1)，并且Macro Cell和Micro Cell均可以作为超级小区的主CP。In actual network coverage, a micro cell (Micro Cell) is often placed within the coverage area of a macro cell (Macro Cell) for hotspot coverage (Hot compensation), as shown in Figure 1. In order to avoid co-channel interference between macro and micro base stations, the macro and micro cells are covered by a cell combination mode to form a macro and micro heterogeneous super cell, in which the macro cell and the micro cell are respectively called a CP of the macro and micro heterogeneous super cells (such as Macro CP0 and Micro CP1), and both Macro Cell and Micro Cell can serve as the primary CP of the super cell.
在宏微超级小区中，超级小区通常继承合并了原宏站小区或者微站小区的PCI、参考信号功率、系统信息块等配置信息。对于LTE网络而言，宏站的下行最大发射功率在40w左右，而微站下行的最大发送功率在1w或者50mw，所以在宏微异构的超级小区中，宏微基站之间的参考信号功率配置差异约20dB，有些场景甚至多达30dB。如图1所示，当小区配置的参考信号功率(Reference Signal Receiving Power，RSRP)为宏站RRU(Radio RemoteUnite)的发射功率时，UE1处于微站覆盖范围，UE1根据参考信号计算的PL大于实际的PL(即PL1大于PL2)。反之当小区配置的参考信号功率为微站RRU的发射功率时，UE2处于宏站覆盖范围，UE2根据参考信号计算的PL小于实际的PL。在上述场景下，如果仅采用当前的PUSCH闭环功控方法来调节UE功率会产生如下问题：In a macro-micro super cell, the super cell usually inherits and combines configuration information such as PCI, reference signal power, and system information block of the original macro cell or micro cell. For the LTE network, the maximum downlink transmit power of the macro station is about 40w, while the maximum downlink transmit power of the micro station is 1w or 50mw, so in the macro-micro heterogeneous super cell, the reference signal power between the macro and micro base stations The configuration difference is about 20dB, and even as much as 30dB in some scenarios. As shown in Figure 1, when the reference signal power (Reference Signal Receiving Power, RSRP) configured in the cell is the transmit power of the macro station RRU (Radio Remote Unite), UE1 is in the coverage of the micro station, and the PL calculated by UE1 according to the reference signal is greater than the actual PL (ie PL1 is greater than PL2). Conversely, when the reference signal power configured in the cell is the transmit power of the micro-station RRU, the UE2 is in the coverage of the macro-station, and the PL calculated by the UE2 according to the reference signal is smaller than the actual PL. In the above scenario, if only the current PUSCH closed-loop power control method is used to adjust the UE power, the following problems will occur:
UE会因为计算的PL大于实际PL，而导致PUSCH发射功率过大，使得功率浪费，增加了上行干扰。Because the calculated PL is larger than the actual PL, the UE will cause the PUSCH transmission power to be too large, which will waste power and increase the uplink interference.
UE会因为计算的PL小于实际PL，而导致PUSCH发射功率不足，使得上行失步的风险增大，降低了用户体验。Because the calculated PL is smaller than the actual PL, the UE will cause insufficient PUSCH transmit power, which increases the risk of uplink desynchronization and reduces user experience.
针对相关技术中用户设备UE无法准确调整发射功率的技术问题，目前尚未提出有效的解决方案。For the technical problem that the user equipment UE cannot accurately adjust the transmit power in the related art, no effective solution has been proposed so far.
