Description
一种确定上行干扰终端的方法和装置 技术领域 Method and device for determining uplink interference terminal
本发明涉及通信领域中的资源适配机制， 具体是一种确定产生小区间上 行干扰终端的方法和装置。 背景技术 The present invention relates to a resource adaptation mechanism in the communication field, and in particular, to a method and apparatus for determining an inter-cell uplink interference terminal. Background technique
目前 3GPP 中正在讨论基于载波聚合的异构网络协调机制， 主要指当未 来网络中应用载波聚合之后， 如何协调网络中不同载波之间的分配， 从而降 低载波间的干扰。 其中， 宏基站与微基站之间的干扰是大家广泛关注的一个 问题。 At present, the heterogeneous network coordination mechanism based on carrier aggregation is being discussed in 3GPP, which mainly refers to how to coordinate the allocation between different carriers in the network after carrier aggregation is applied in the future network, thereby reducing interference between carriers. Among them, the interference between the macro base station and the micro base station is a problem that has been widely concerned.
当宏基站小区与微基站小区分别使用载波聚合技术时， 两个小区边缘的 终端可以通过协调载波的分配， 以降低小区间的干扰。 如图 1所示， 当宏终 端在载波 3以及 4上驻留时， 会对微基站产生较大干扰， 此时可以将宏终端 移到载波 1以及 2上， 从而在保证用户体验的同时， 降低干扰。 When the macro base station cell and the micro base station cell respectively use the carrier aggregation technology, the terminals at the two cell edges can coordinate the allocation of carriers to reduce inter-cell interference. As shown in FIG. 1, when the macro terminal camps on carriers 3 and 4, it will cause large interference to the micro base station. At this time, the macro terminal can be moved to carriers 1 and 2, thereby ensuring the user experience while ensuring the user experience. Reduce interference.
通过进一歩分析可以了解， 由于终端可以通过功率控制等方案解决下行 干扰问题， 或者在微基站下行信号较强时， 切换到微基站。 因此上行干扰为 主要关注点。 It can be understood from further analysis that the terminal can solve the downlink interference problem through a scheme such as power control, or switch to the micro base station when the downlink signal of the micro base station is strong. Therefore, uplink interference is the main concern.
由于宏基站与微基站发射功率不同， 因此覆盖范围不同。 下行时可以 保证到终端的发射功率基本相差不大， 从而避免对于相邻小区终端的下行干 扰。 而上行发送时， 由于终端有用信号需要被宏基站侧接收到， 因此会对相 邻的微基站造成较大的干扰， 如图 2所示。 Since the macro base station and the micro base station have different transmission powers, the coverage ranges are different. When downlinking, it can be ensured that the transmission power to the terminal is basically different, thereby avoiding downlink interference to neighboring cell terminals. In the uplink transmission, since the useful signal of the terminal needs to be received by the macro base station side, it causes large interference to the adjacent micro base station, as shown in FIG. 2 .
尽管可以通过之前叙述的载波聚合的方案， 将终端调整到干扰较小的载 波以避免所述干扰， 但是由于终端此时连接到宏基站， 因此一方面微基站并 不知道哪个宏基站的哪个终端对于自身上行造成了干扰； 另外一方面宏基站 以及该终端也不知道自身已经对于微基站造成了干扰。 Although the terminal can be adjusted to the carrier with less interference to avoid the interference by the previously described carrier aggregation scheme, since the terminal is connected to the macro base station at this time, on the one hand, the micro base station does not know which terminal of the macro base station The interference is caused by its own uplink; on the other hand, the macro base station and the terminal do not know that they have caused interference to the micro base station.
因此如何确定上行干扰终端成为了亟待解决的一个问题。 Therefore, how to determine the uplink interference terminal has become an urgent problem to be solved.
现有解决该问题的方案有如下两种思路： The existing solutions to solve this problem have the following two ideas:
思路 1 : 可以通过实现的方式解决， 即微基站测量出上行干扰较大时，
避免在该载波资源上调度终端； 但是该方案限制了微基站对于资源的使用， 影响了微基站下驻留终端的性能； 特别是当宏基站小区负载多、 需要微基站 小区进行 offload需求时， 那么微基站下面驻留终端较多时， 这种方法还是会 影响调度时延和服务质量。 Idea 1: It can be solved by means of implementation, that is, when the micro base station measures the uplink interference is large, Avoid scheduling the terminal on the carrier resource; however, the scheme limits the use of the resource by the micro base station, and affects the performance of the terminal station under the micro base station; especially when the macro base station cell has a large load and needs the micro base station cell to perform the offload requirement, When the number of terminals residing under the micro base station is large, this method will still affect the scheduling delay and quality of service.
思路 2: 宏基站通过网管配置的方式了解微基站的位置， 并通过定位的 方式定位终端的位置， 找出可能对于微基站产生上行干扰的终端， 并针对其 进行相应操作， 如调整到相应的载波上等； 然而该方式的缺点是对于网管以 及定位功能提出了更高的需求， 增加了复杂度。 Idea 2: The macro base station learns the location of the micro base station through the configuration of the network management system, and locates the location of the terminal by means of positioning, finds the terminal that may generate uplink interference to the micro base station, and performs corresponding operations on it, such as adjusting to corresponding The carrier is superior; however, the disadvantage of this method is that it has higher requirements for the network management and the positioning function, which increases the complexity.
由于现有的解决方案不够理想， 因此本发明将提出一种新的上行干扰终 端的发现机制。 Since the existing solution is not ideal, the present invention will propose a new discovery mechanism for the uplink interference terminal.

以下结合附图对本发明的优选实施例进行说明， 应当理解， 此处所描述 的优选实施例仅用于说明和解释本发明， 并不用于限定本发明。 The preferred embodiments of the present invention are described with reference to the accompanying drawings, and the preferred embodiments of the present invention are intended to illustrate and explain the invention.
根据本发明的一个最佳实施方式， 一种确定上行干扰终端的方法包括以 下歩骤： 1 )第一基站在测量上行物理资源块 （PRB) 负载信息时， 记录上行 干扰产生时间； 2) 第一基站在干扰信息指示消息中加入与所述上行 PRB干 扰信息对应的干扰产生时间信息， 并将所述干扰信息指示消息发送给第二基 站; 3 ) 第二基站通过所述干扰信息指示消息中的时间信息以及该时间点上 PRB的分配确认出所述上行 PRB对应的终端。以下将对每个歩骤进行详细的 描述。 According to a preferred embodiment of the present invention, a method for determining an uplink interference terminal includes the following steps: 1) a first base station records an uplink interference generation time when measuring uplink physical resource block (PRB) load information; 2) a base station adds interference generation time information corresponding to the uplink PRB interference information to the interference information indication message, and sends the interference information indication message to the second base station; 3) the second base station indicates, by using the interference information indication message The time information and the allocation of the PRB at the time point confirm the terminal corresponding to the uplink PRB. Each step will be described in detail below.
1. 第一基站在测量上行 PRB负载信息时， 记录上行干扰产生时间。 现有技术中， 已有多种方式能够实现基站对上行干扰 PRB的测量， 本发 明的背景技术部分中亦有所介绍， 因此不再详细描述。 在本歩骤中， 测量方 式并不重要， 重要的是在测量的同时记录干扰产生的时间。 1. When the first base station measures uplink PRB load information, it records the uplink interference generation time. In the prior art, there are various ways to implement the measurement of the uplink interference PRB by the base station, which is also described in the background of the present invention, and therefore will not be described in detail. In this step, the measurement method is not important. It is important to record the time of the disturbance while measuring.
2. 第一基站在干扰信息指示消息中加入与所述上行 PRB 干扰信息对应 的干扰产生时间信息， 并将所述干扰信息指示消息发送给第二基站。 2. The first base station adds interference generation time information corresponding to the uplink PRB interference information to the interference information indication message, and sends the interference information indication message to the second base station.
本歩骤是本发明的核心。 在不同的通信网络中， 干扰信息指示消息可以 是不同的信令。 例如， 在 LTE系统中， 目前基站间可以通过 Load Information (3GPP TS 36.423 vlO.2.0)消息交互每个小区上行 PRB的干扰情况以及是否 需要避免的情况， 如图 3所示。 通过该信息的交互， 能够确定相邻小区哪个 上行 PRB受到的干扰较为严重， 从而作为后续调度的参考。 在其他系统中， 也可以通过其他信令来传递干扰信息指示消息， 如基站配置更新 （eNB Configuration Update 本领域技术人员应能理解， 在不同的通信系统中， 还 可以专门设计其他类型的干扰信息指示消息， 也能够实现本发明的目的。 This step is the core of the present invention. In different communication networks, the interference information indication message may be different signaling. For example, in the LTE system, the interference between the uplink PRBs of each cell and whether it needs to be avoided can be exchanged between the base stations through the Load Information (3GPP TS 36.423 vlO.2.0) message, as shown in Figure 3. Through the interaction of the information, it can be determined which uplink PRB of the neighboring cell is subjected to serious interference, and thus serves as a reference for subsequent scheduling. In other systems, interference information indication messages may also be transmitted through other signaling, such as base station configuration update (eNB Configuration Update, those skilled in the art should understand that other types of interference information may be specially designed in different communication systems. The purpose of the present invention can also be achieved by indicating a message.
然而目前的 Load information并非实时交互，而是一段时间（例如 100ms) 的统计值， 因此无法确认究竟是哪个终端对于微基站小区造成了较为严重的
上行干扰。 However, the current load information is not a real-time interaction, but a statistical value of a period of time (for example, 100 ms), so it is impossible to confirm which terminal is causing a serious problem to the micro base station cell. Uplink interference.
以 LTE系统为例， 可以在 Load information或者专门的干扰信息指示消 息中引入时间信息， 通过时间信息以及该时间点上 PRB的分配可以唯一确认 出上行资源分配给哪个终端， 从而确认出上行干扰终端的身份。 Taking the LTE system as an example, the time information can be introduced in the load information or the special interference information indication message. The time information and the allocation of the PRB at the time point can uniquely identify which terminal the uplink resource is allocated to, thereby confirming the uplink interference terminal. identity of.
其中， 具体时间信息的设计可以是： The specific time information can be designed as follows:
每一个时间信息对应每一个瞬时的 PRB的干扰标识； 或者 Each time information corresponds to the interference identifier of each transient PRB; or
每一个或者多个时间信息对应 PRB的统计干扰标识产生结果中最大的一 个或者几个上行干扰产生的时间。 Each time or pieces of time information corresponds to the time at which the largest one or several uplink interferences are generated in the statistical interference flag of the PRB.
也就是说， 可以针对每个瞬时的干扰 PRB加入时间信息， 这样可以确认 每个 PRB的干扰时间， 从而在后续歩骤中确认每个干扰 PRB所对应的终端； 也可以只针对干扰最为严重的一个或几个 PRB加入时间信息， 从而再后续歩 骤中仅确认产生干扰最严重的终端， 也能够实现本发明的目的。 That is to say, time information can be added for each instantaneous interfering PRB, so that the interference time of each PRB can be confirmed, thereby confirming the terminal corresponding to each interfering PRB in a subsequent step; or only for the most severe interference The purpose of the present invention can also be achieved by adding time information to one or several PRBs, so that only the terminals with the most severe interference are confirmed in subsequent steps.
其中， 时间信息的设计形式可以是绝对时间戳或者系统帧号 （SF ) 加 子帧的方式： The time information may be designed in the form of an absolute time stamp or a system frame number (SF) plus a subframe:
1 )绝对时间戳的形式， 即通过绝对时间的形式标识该上行干扰产生的时 间， 如 XX年 XX月 XX日 XX分 XX秒 XX毫秒 1) The form of the absolute time stamp, that is, the time of the uplink interference is identified by the absolute time form, such as XX year XX month XX day XX minute XX seconds XX milliseconds
例如， 在 LTE系统中， 将绝对时间戳信息加入到 Load information消息 中后， 新的 Load information消息格式可以是： 反馈的 PRB1 , 干扰级别： 高， 产生时间： XX年 XX月 XX曰 XX分 XX秒 XX毫秒。 For example, in the LTE system, after the absolute timestamp information is added to the Load information message, the new Load information message format can be: Feedback PRB1, Interference level: High, Generation time: XX year XX month XX曰XX points XX Seconds XX milliseconds.
2) SF 帧加子帧的形式， 在 TDD通信中， 由于基站同歩， 所以可以通 过帧号确定该上行 PRB测量的无线帧， 由于一个无线帧中包含 10个子帧， 因此再通过子帧号唯一确认发送的子帧位置， 随后就可以通过 PRB号确认子 帧中发送的 PRB资源位置， 从而确认终端身份。 2) In the form of SF frame plus subframe, in TDD communication, since the base station is the same, the radio frame of the uplink PRB measurement can be determined by the frame number. Since one radio frame contains 10 subframes, the subframe number is passed again. The location of the transmitted subframe is uniquely confirmed, and then the location of the PRB resource transmitted in the subframe can be confirmed by the PRB number, thereby confirming the identity of the terminal.
将 SF 帧及子帧加入到 Load information消息中后，新的 Load information 消息格式可以是： 反馈的 PRB1 , 干扰级别： 高， 产生时间： SF xx, 子帧 After the SF frame and the subframe are added to the Load information message, the new Load information message format can be: Feedback PRB1, Interference level: High, Generation time: SF xx, Subframe
XX XX
3. 第二基站通过所述干扰信息指示消息中的时间信息以及该时间点上 PRB的分配确认出所述上行 PRB对应的终端。 3. The second base station confirms the terminal corresponding to the uplink PRB by using the time information in the interference information indication message and the allocation of the PRB at the time point.
根据歩骤 2 中得到的与对临小区产生干扰的 PRB所对应的干扰产生时
间， 可以从 PRB的分配确认出每个 PRB对应的终端。 现有技术中基站已经 具备这种能力， 此处不再详细描述。 When the interference corresponding to the PRB that interferes with the adjacent cell obtained in step 2 is generated In the meantime, the terminal corresponding to each PRB can be confirmed from the allocation of the PRB. The base station in the prior art already has this capability and will not be described in detail herein.
本领域技术人员应能理解， 正如本发明背景技术部分所描述的， 本发明 的一个重要目的是确认微基站所受到的宏基站与宏终端之间通信的干扰。 因 此， 在本发明的一些优选实施例中， 确认上行干扰终端的方法中的第一基站 可以是微基站， 第二基站则是宏基站； 或者第一基站可以是家庭基站 （或称 为微微基站）， 第二基站则是微基站。 It will be understood by those skilled in the art that, as described in the Background of the Invention, an important object of the present invention is to confirm the interference of communication between a macro base station and a macro terminal to which a micro base station is subjected. Therefore, in some preferred embodiments of the present invention, the first base station in the method for confirming the uplink interference terminal may be a micro base station, and the second base station is a macro base station; or the first base station may be a home base station (or called a pico base station) ), the second base station is a micro base station.
