一种家庭基站的信号调节方法、家庭基站及终端A signal adjustment method of home base station, home base station and terminal

技术领域technical field

本发明涉及无线通信领域，尤其涉及一种家庭基站的信号调节方法、家庭基站及终端。The present invention relates to the field of wireless communication, in particular to a signal adjustment method of a home base station, a home base station and a terminal.

背景技术Background technique

家庭基站，也称毫微微米蜂窝基站，用于为室内覆盖提供增强的移动语音和数据业务，并由于其良好的频谱性能，而受到业界的广泛应用。然而，家庭基站技术仍处于起步阶段，用户由于空间、辐射等条件的限制将家庭基站部署在一个不合理的位置，例如角落、墙后、窗台等，造成信号远离用户、受墙体穿透损耗、向室外泄露等问题，不仅达不到对室内的良好覆盖还可能对室外用户形成干扰。Femtocells, also known as femtocells, are used to provide enhanced mobile voice and data services for indoor coverage, and are widely used in the industry due to their good spectrum performance. However, femtocell technology is still in its infancy. Users deploy femtocells in unreasonable locations due to space and radiation constraints, such as corners, behind walls, windowsills, etc., causing signals to be far away from users and subject to wall penetration loss. , Leakage to the outdoors and other issues, not only can not achieve good indoor coverage, but also may cause interference to outdoor users.

针对上述问题，现有的关于家庭基站优化的技术方案主要有两种：一、采用频谱资源分配的方法避免家庭基站与宏基站之间的干扰。具体的，根据不同基站在各段频谱上的信号质量、用户数量、用户优先级等因素，计算不同频谱分配方案所得到的回报，按照一定策略和回报要求，在宏基站与家庭基站之间进行频谱的优化分配。二、采用功率控制的方法提高覆盖质量和用户业务速率。具体的，用户处在不同的信道时，根据信道信号强度高低和用户业务的需求为用户设定合理的基站或终端发射功率，以实现功率效用最大化以及减少与宏基站之间的干扰。In view of the above problems, there are mainly two existing technical solutions for HNB optimization: 1. Using spectrum resource allocation method to avoid interference between HNB and macro NB. Specifically, according to the signal quality of different base stations on each segment of spectrum, the number of users, user priority and other factors, calculate the rewards obtained by different spectrum allocation schemes, and carry out between the macro base station and the home base station according to certain strategies and reward requirements. Optimal allocation of spectrum. 2. The method of power control is adopted to improve the coverage quality and user service rate. Specifically, when the user is on different channels, set a reasonable base station or terminal transmit power for the user according to the signal strength of the channel and the user's service requirements, so as to maximize power utility and reduce interference with the macro base station.

在实现上述家庭基站的信号调节的过程中，发明人发现现有技术中至少存在如下问题：采用频谱分配的方法可以解决家庭基站与宏基站之间的干扰，但是不能提升家庭基站本身的覆盖范围，无法增强信号较弱的地方（如墙角）。由于家庭基站本身的功率大小有限制，因此采用功率控制的方法容易在增大功率的同时，使得家庭基站的覆盖范围移到居住范围以外，造成信号外泄。In the process of realizing the signal adjustment of the above-mentioned home base station, the inventor found that there are at least the following problems in the prior art: the spectrum allocation method can solve the interference between the home base station and the macro base station, but cannot improve the coverage of the home base station itself , unable to enhance places with weak signals (such as corners). Since the power of the home base station itself is limited, the method of power control is easy to increase the power while moving the coverage area of the home base station beyond the residential area, resulting in signal leakage.

具体实施方式detailed description

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

本发明实施例提供了一种家庭基站的信号调节方法，所述方法应用于家庭基站中，如图1所示，所述方法包括：An embodiment of the present invention provides a method for adjusting a signal of a home base station. The method is applied to a home base station, as shown in FIG. 1 , and the method includes:

步骤101、接收终端发送的至少一个信号强度信息，每个信号强度信息中携带有信号强度小于最大信号强度的预设比值的位置上的信号强度。Step 101, receiving at least one piece of signal strength information sent by a terminal, each signal strength information carrying signal strengths at locations where the signal strength is less than a preset ratio of the maximum signal strength.

信号强度信息具体可为但不限于语音呼叫信息。信号强度用于表示终端发出所述信号强度信息所在位置上各个天线阵子中的信号强度。信号强度用一个物理信号向量的复数形式表示，任意一个信号强度u_k=（u_k,1,u_k,2...u_k,N)，其中N为家庭基站天线振子的总数，每个天线阵子上的信号强度可由现有公式计算得到，|u_k,i|是信号幅度，φ_i是信号相位。The signal strength information may specifically be but not limited to voice call information. The signal strength is used to indicate the signal strength of each antenna element at the location where the terminal sends the signal strength information. The signal strength is expressed in the complex form of a physical signal vector, any signal strength u_k = (u_k,1 ,u_k,2 ...u_k,N ), where N is the total number of home base station antenna elements, each The signal strength on the antenna array can be calculated by the existing formula Calculated, |u_k,i | is the signal amplitude, φ_i is the signal phase.

步骤102、根据天线数量划分与天线数量对应的至少一个位置区域。Step 102: Divide at least one location area corresponding to the number of antennas according to the number of antennas.

根据GPS定位，如图2所示，以正北方向为法线0°，顺时针在逻辑上将整个覆盖区域的水平切面等分为N-1个扇形的位置区域，N是家庭基站天线振子的总数，每个扇区角都是2π/(N-1),因此第i个区域的中心角为θ_i=（2i+1)π/(N-1)。According to GPS positioning, as shown in Figure 2, with the north direction as the normal line 0°, the horizontal section of the entire coverage area is logically divided into N-1 fan-shaped location areas clockwise, and N is the home base station antenna oscillator The total number of each sector angle is 2π/(N-1), so the central angle of the i-th area is θ_i = (2i+1)π/(N-1).

步骤103、计算每个信号强度对应位置所在的位置区域。Step 103, calculating the location area where each signal strength corresponds to the location.

假设家庭基站一共接收到K次测量报告，物理信号依次记为u₁..u_k..u_K，对每个信号u_k，估算每个信号强度对应位置所在的位置区域，即用户发送信号u_k时相对家庭基站的位置。可通过计算每个信号的到达角确定其所在的位置区域，具体的：计算u_k的相关矩阵再计算其中${a_i}^H=[1,e^{\mathrm{j\π}\cos ({\mathrm{\θ}}_i-2\mathrm{\π}/N)},...,e^{\mathrm{j\π}\cos ({\mathrm{\θ}}_i-2\mathrm{\π}\·(N-1)/N)}].$i=1～N，θ_i是各个位置区域的中心角。A_i用于表示一个信号强度包含的天线阵子上的信号强度，从A₁-A_n中找出最大的A_i代表信号强度u_k所在的位置区域。通过计算到达角，能够确定每个信号强度对应位置所在的位置区域。此外，由于家庭环境中每个区域i的面积相对都较小，所以用户处于区域i任一点时都可近似认为相对于家庭基站法线的角度为θ_i。这样就确定了用户发送信号u_k时所处的区域i和相对角度θ_i。Assume that the home base station has received K measurement reports in total, and the physical signals are sequentially recorded as u₁ ..u_k ..u_K . For each signal u_k , estimate the location area where each signal strength corresponds to the location, that is, the user sends the signal relative to the position of the femtocell at u_k . The location area where each signal is located can be determined by calculating the angle of arrival of each signal, specifically: calculate the correlation matrix of u_k recalculate in${a_i}^h=[1,e^{\mathrm{j\π}\cos ({\mathrm{\θ}}_i-2\mathrm{\π}/N)},...,e^{\mathrm{j\π}\cos ({\mathrm{\θ}}_i-2\mathrm{\π}\&Center\; Dot;(N-1)/N)}].$ i=1～N, θ_i is the central angle of each location area. A_i is used to represent the signal strength on the antenna elements included in a signal strength, and the largest A_i is found from A₁ -A_n to represent the location area where the signal strength u_k is located. By calculating the angle of arrival, the location area where the location corresponding to each signal strength is located can be determined. In addition, since the area of each area i in the home environment is relatively small, when the user is at any point in area i, the angle relative to the normal line of the home base station can be approximately considered to be θ_i . In this way, the area i and the relative angle θ_i where the user sends the signal u_k are determined.

步骤104、分别统计每个位置区域中的边缘信号强度，边缘信号强度为位置区域中信号强度最低的信号强度。Step 104: Count the edge signal strengths in each location area respectively, where the edge signal strength is the signal strength with the lowest signal strength in the location area.

由于位置区域i中可能发出多个信号u_k，因此取位置区域i中信号强度最低的A_i作为边缘信号强度R_i。Since multiple signals u_k may be sent out in the location area i, the A_i with the lowest signal strength in the location area i is taken as the edge signal strength R_i .

步骤105、根据每个边缘信号强度与预设信号强度的差值确定覆盖评估参数。Step 105. Determine coverage evaluation parameters according to the difference between the signal strength of each edge and the preset signal strength.

预设信号强度R_best可根据通常的网络信号强度进行设置，如设置为4db。为覆盖评估参数AD设置取值范围，进而根据AD在取值范围中的位置即可确定当前家庭基站的安放位置是否合理。取值范围如0<AD<100。每个边缘信号强度与预设信号强度的差值确定覆盖评估参数的公式如下：其中i=1～N-1。The preset signal strength R_best can be set according to the usual network signal strength, for example, it is set to 4db. A value range is set for the coverage evaluation parameter AD, and then according to the position of AD in the value range, it can be determined whether the current placement position of the femtocell is reasonable. The value range is such as 0<AD<100. The formula for determining the coverage evaluation parameter by the difference between the signal strength of each edge and the preset signal strength is as follows: Where i=1～N-1.

步骤106、显示覆盖评估参数，以便用户根据覆盖评估参数调节家庭基站位置。Step 106, displaying the coverage evaluation parameters, so that the user can adjust the position of the home base station according to the coverage evaluation parameters.

覆盖评估参数通过家庭基站的显示屏进行显示，覆盖评估参数数值越高表示家庭基站部署位置越合理。The coverage evaluation parameters are displayed on the display screen of the home base station, and the higher the value of the coverage evaluation parameter, the more reasonable the deployment position of the home base station is.

如果分数低于预定数值（如小于50），则通过显示屏通过非常规显示方式提示用户，非常规方式包括：闪烁、加亮等方式。If the score is lower than the predetermined value (such as less than 50), the user will be prompted through the display screen through unconventional display methods, including: flashing, highlighting, etc.

本发明实施例提供的家庭基站的信号调节方法、家庭基站及终端，能够根据天线数量划分位置区域，并将接收的至少一个信号强度信息中携带的每个信号强度对应到每个位置区域中，在统计每个位置区域中的最小信号强度之后，根据每个边缘信号强度与预设信号强度的差值确定覆盖评估参数，以便用户根据所述覆盖评估参数调节家庭基站位置。现有技术中，采用对家庭基站的信号调节采用频谱资源分配的方法和功率控制的方法，只能够在不改变家庭基站位置的前提下，调节频谱资源以及功率。本发明中，通过显示计算得到的覆盖评估参数，能够使用户获知当前家庭基站的摆放位置是否合理，覆盖评估参数越高则越适于摆放。用户通过调节家庭基站的位置能够解决覆盖范围不足以及信号外泄的问题。The home base station signal adjustment method, home base station, and terminal provided in the embodiments of the present invention can divide location areas according to the number of antennas, and correspond each signal strength carried in at least one piece of received signal strength information to each location area, After the minimum signal strength in each location area is counted, the coverage evaluation parameter is determined according to the difference between the signal strength of each edge and the preset signal strength, so that the user can adjust the position of the home base station according to the coverage evaluation parameter. In the prior art, the spectrum resource allocation method and the power control method are adopted for signal adjustment of the HNB, and the spectrum resource and power can only be adjusted without changing the location of the HNB. In the present invention, by displaying the calculated coverage evaluation parameters, the user can know whether the current placement position of the home base station is reasonable, and the higher the coverage evaluation parameter is, the more suitable it is for placement. Users can solve the problems of insufficient coverage and signal leakage by adjusting the location of the home base station.

在使用过程中，发明人还发现下述问题，室内局部信号很强同时另一局部信号很弱，在弥补信号很弱的局部的信号质量而提高家庭基站的功率时，会在原信号很强的位置出现信号外溢的问题。为了解决上述问题，本发明实施例还提供了一种家庭基站的信号调节方法，作为对图1所示方法的进一步说明，如图3所示，所述方法还包括：In the process of use, the inventor also found the following problem. The signal in one part of the room is strong while the signal in another part is weak. There is a problem of signal overflow in the position. In order to solve the above problems, an embodiment of the present invention also provides a signal adjustment method for a home base station, as a further description of the method shown in FIG. 1 , as shown in FIG. 3 , the method further includes:

步骤201、查找全部边缘信号强度中的最小边缘信号强度。Step 201. Find the minimum edge signal strength among all edge signal strengths.

在N-1个位置区域对应的边缘信号中，查找数值最小的边缘信号强度，作为最小边缘信号强度Rx。Among the edge signals corresponding to the N-1 location areas, find the edge signal strength with the smallest value as the minimum edge signal strength Rx.

步骤202、将最小边缘信号强度Rx所在位置区域x的中心角θ_x对应的天线阵子的增益值确定为第一增益值。Step 202. Determine the gain value of the antenna element corresponding to the central angle θ_x of the area x where the minimum edge signal strength Rx is located as the first gain value.

作为一个举例，第一增益值g_x可设置为1。As an example, the first gain value g_x may be set to 1.

步骤203、分别根据其余每个边缘信号强度Ri与最小边缘强度Rx确定其余每个边缘信号强度所在位置区域的中心角对应的天线阵子的第二增益值。Step 203 : Determine the second gain value of the antenna element corresponding to the central angle of the location area where each remaining edge signal strength is located according to the remaining edge signal strength Ri and the minimum edge strength Rx respectively.

若第一增益值设置为1，则各中心角θ_i的天线增益为g_i=R_x/R_i。最终得到各个中心角对应的天线增益的集合G=[g₁,...,g_N-1]。If the first gain value is set to 1, the antenna gain of each central angle θ_i is g_i =R_x /R_i . Finally, a set G=[g₁ ,...,g_N-1 ] of antenna gains corresponding to each central angle is obtained.

步骤204、根据第一增益值和第二增益值确定每个天线阵子的权值。Step 204: Determine the weight of each antenna element according to the first gain value and the second gain value.

不同的天线阵列计算权值的方法不尽相同，本实施例仅以圆形阵列天线作为举例，对计算权值的过程进行描述。权值ω=(A·A^H)^-1·A·G，其中A=[a₁,...a_i,...a_N-1]，${a_i}^H=[1,e^{\mathrm{j\&pi;}\cos ({\mathrm{\&theta;}}_i-2\mathrm{\&pi;}/N)},...,e^{\mathrm{j\&pi;}\cos ({\mathrm{\&theta;}}_i-2\mathrm{\&pi;}\&CenterDot;(N-1)/N)}].$Different antenna arrays have different methods for calculating weights, and this embodiment only uses circular array antennas as an example to describe the process of calculating weights. Weight ω=(A·A^H )^-1 ·A·G, where A=[a₁ ,...a_i ,...a_N-1 ],${a_i}^h=[1,e^{\mathrm{j\&pi;}\cos ({\mathrm{\&theta;}}_i-2\mathrm{\&pi;}/N)},...,e^{\mathrm{j\&pi;}\cos ({\mathrm{\&theta;}}_i-2\mathrm{\&pi;}\&Center\; Dot;(N-1)/N)}].$

步骤205、根据权值调节每个天线阵子的输出功率。Step 205, adjust the output power of each antenna element according to the weight.

本发明实施例提供的家庭基站的信号调节方法，能够通过设置天线辐射在角度θ₁,θ₂...θ_N-1的增益来优化家庭基站的覆盖。调节天线阵列权值后，任意位置区域i的边缘信号强度R_i均接近于R_x。在调节天线增益后，能够克服室内信号强度不均的问题。The signal adjustment method of the home base station provided by the embodiment of the present invention can optimize the coverage of the home base station by setting the gains of antenna radiation at angles θ₁ , θ₂ ... θ_N-1 . After adjusting the weights of the antenna array, the edge signal strength R_i of any location area i is close to R_x . After adjusting the antenna gain, the problem of uneven indoor signal strength can be overcome.

本发明实施例还提供了一种家庭基站的信号调节方法，作为对图1所示方法的进一步说明，如图4所示，所述方法还包括：The embodiment of the present invention also provides a signal adjustment method of a home base station, as a further description of the method shown in Figure 1, as shown in Figure 4, the method further includes:

步骤301、根据预设信号强度R_best与每个边缘信号强度的差值，确定每个边缘信号强度对应的天线阵子的调节功率。Step 301 , according to the difference between the preset signal strength R_best and each edge signal strength, determine the adjusted power of the antenna element corresponding to each edge signal strength.

步骤302、根据每个调节功率分别调节每个天线阵子的功率。Step 302. Adjust the power of each antenna element respectively according to each adjusted power.

假设家庭基站当前的发射功率为F₁，家庭基站将功率调节为F₂=F₁+(R_best-R_x)，使得各区域的边缘信号强度都变为R_best。Assuming that the current transmission power of the HNB is F₁ , the HNB adjusts the power to F₂ =F₁ +(R_best -R_x ), so that the edge signal strength of each area becomes R_best .

本发明实施例提供的一种家庭基站的信号调节方法，能够使室内边缘各处覆盖的信号强度均为预设信号强度，在保证无信号外溢的情况下，提高室内整体信号强度。The embodiment of the present invention provides a signal adjustment method for a home base station, which can make the signal strengths of all coverages at the edge of the room be the preset signal strength, and improve the overall signal strength of the room while ensuring no signal overflow.

本发明实施例还提供了一种家庭基站的信号调节方法，作为对图1所示方法的进一步描述，如图5所示，所述方法还包括：An embodiment of the present invention also provides a signal adjustment method for a home base station, as a further description of the method shown in FIG. 1 , as shown in FIG. 5 , the method further includes:

步骤401、根据预设周期监测覆盖范围内的终端切入操作或切出操作，切入操作为从宏基站切换到家庭基站的操作，切出操作为从家庭基站切换到宏基站的操作。Step 401. Monitor the terminal cut-in operation or hand-out operation within the coverage area according to a preset period. The hand-in operation is the operation of handing over from the macro base station to the home base station, and the hand-out operation is the operation of handing over from the home base station to the macro base station.

预设周期如1小时。当家庭基站网络的信号强度低于正常值时，终端将与宏基站进行连接，即切出操作，进而改善信号质量。The default cycle is 1 hour. When the signal strength of the home base station network is lower than the normal value, the terminal will connect with the macro base station, that is, cut out operation, thereby improving the signal quality.

步骤402、获取切入操作或切出操作所在的位置区域。Step 402, obtaining the location area where the cut-in operation or the cut-out operation is located.

预设比例如当前天线增益的百分之十。The preset ratio is, for example, ten percent of the current antenna gain.

步骤404、如果产生切出操作，则根据预设比例增加位置区域对应的天线阵子的增益。Step 404: If a cut-out operation occurs, increase the gain of the antenna element corresponding to the location area according to a preset ratio.
