Description
技术领域technical field
本发明涉及一种利用数字图像处理技术实现纸病的检测方法，特别涉及一种prach抗干扰技术中支持小区间联合检测的方法。The invention relates to a method for detecting paper defects by using digital image processing technology, in particular to a method for supporting inter-cell joint detection in prach anti-jamming technology.
背景技术Background technique
现有的prach(物理随机接入信道)抗干扰技术为基于单小区的底噪测量实现，当小区覆盖范围内出现时域上连续或针对LTE系统上行子帧的脉冲干扰时，eNB(evolvedNode B，演进型基站)可通过底噪测量获得一段时间内(该定时器可自行设置)的频域上每个prb(PHYSICAL RESOURCE BLOCK：物理资源块)的噪声平均值，当某prb的噪声平均值高于一定门限(该噪声门限可自行设置)时，则将该prb视为被干扰的prb，此时将会对其进行抗干扰处理，如果该prb落在prach所预留的资源位置中，则会触发prach抗干扰流程。The existing prach (Physical Random Access Channel) anti-interference technology is implemented based on the noise floor measurement of a single cell. When there is continuous time domain or pulse interference targeting the uplink subframe of the LTE system within the coverage of the cell, the eNB (evolvedNode B , evolved base station) can obtain the average noise value of each prb (PHYSICAL RESOURCE BLOCK: physical resource block) in the frequency domain for a period of time (the timer can be set by itself) through noise floor measurement. When the average noise value of a prb When it is higher than a certain threshold (the noise threshold can be set by itself), the prb is regarded as an interfered prb, and anti-interference processing will be performed on it at this time. If the prb falls in the resource position reserved by prach, It will trigger the prach anti-interference process.
当prach预留的资源中有至少一个prb被干扰时，则会出发prach抗干扰流程，目前的prach抗干扰处理基于单小区的prach配置，当prach被干扰时，则eNB会自动改变prach的频偏，将prach向prb编号大的高频方向移动至干扰区以外，如果干扰区以外的高频区域不足6个prb，则从prb 0开始重新选择合适的位置。Prach频偏调整完成后，RRC(指无线资源控制)层会更新系统信息，并发出SIB更新的paging要求小区下的UE更新系统信息。When at least one prb in the resources reserved by prach is interfered, the prach anti-interference process will be initiated. The current prach anti-interference processing is based on the prach configuration of a single cell. When the prach is interfered, the eNB will automatically change the frequency of the prach. If there are less than 6 prbs in the high-frequency area outside the interference area, move the prach to the high-frequency direction with a large prb number outside the interference area, and re-select a suitable position from prb 0. After the Prach frequency offset adjustment is completed, the RRC (referring to radio resource control) layer will update the system information, and send a SIB update paging to request the UE under the cell to update the system information.
采用目前的抗干扰方案，在单小区覆盖或小区较少(可以通过手动配置从时域上区分开prach位置)的场景下可以有效的实现prach抗干扰目的，但当覆盖的小区较多，由于时域位置有限，无法通过手动配置从时域上彻底区分开prach资源位置时，如果同一种干扰在该覆盖区大范围存在，通过现有的实现方案则会造成prach资源碰撞的情况，造成prach虚检或漏检。Using the current anti-jamming solution, the prach anti-jamming purpose can be effectively achieved in the scenario of a single cell coverage or a small number of cells (the location of prach can be distinguished from the time domain by manual configuration), but when there are many covered cells, due to When the location in the time domain is limited, and it is impossible to completely distinguish the location of the prach resource in the time domain through manual configuration, if the same type of interference exists in a large area of the coverage area, the existing implementation scheme will cause a collision of the prach resource, resulting in prach False detection or missed detection.
发明内容Contents of the invention
为了克服上述现有技术的不足，本发明的目的在于提出一种prach抗干扰技术中支持小区间联合检测的方法，能够有效解决由于抗干扰功能生效后导致Prach位置不可控而造成相邻小区Prach资源重叠的问题，以减少Prach虚检与漏检事件发生，具有效率高、准确性高的特点。In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to propose a method for supporting inter-cell joint detection in the prach anti-jamming technology, which can effectively solve the problem of the uncontrollable position of Prach caused by the uncontrollable position of Prach after the anti-jamming function takes effect. The problem of overlapping resources to reduce the occurrence of Prach false detection and missed detection has the characteristics of high efficiency and high accuracy.
为了实现上述目的，本发明采用的技术方案是：In order to achieve the above object, the technical scheme adopted in the present invention is:
一种prach抗干扰技术中支持小区间联合检测的方法，步骤如下：A method for supporting inter-cell joint detection in a prach anti-interference technology, the steps are as follows:
若本小区A检测到干扰并触发prach抗干扰流程时邻小区B尚未进行PRACH频域的抗干扰，则本小区A获得了邻小区B的PRACH频域位置，且两个小区的PRACH位置不重叠，本小区A需从频域干扰和邻小区B的PRACH频域位置之外的频域位置选择可用的PRACH位置；If the cell A detects the interference and triggers the prach anti-interference process, the neighboring cell B has not yet implemented the PRACH frequency domain anti-interference, then the cell A obtains the PRACH frequency domain position of the neighboring cell B, and the PRACH positions of the two cells do not overlap , the cell A needs to select an available PRACH position from frequency domain positions other than the frequency domain interference and the PRACH frequency domain position of the neighboring cell B;
若本小区A检测到干扰并触发prach抗干扰流程时邻小区B已完成PRACH频域的抗干扰，且邻小区B的PRACH频域位置已更新，则本小区A需从频域干扰和更新后的邻小区B的PRACH频域位置之外的频域位置选择可用的PRACH位置；If the cell A detects interference and triggers the prach anti-interference process, the adjacent cell B has completed the anti-interference in the PRACH frequency domain, and the PRACH frequency domain position of the adjacent cell B has been updated, then the cell A needs to start from the frequency domain interference and update Select an available PRACH position at a frequency domain position other than the PRACH frequency domain position of the neighboring cell B;
若本小区A和邻小区B同时检测到干扰并触发抗干扰流程，各自将当前PRACH的频域位置制为无效，并通知给对方小区，选取两个小区中PCI较大的一方优先进行频域位置选择，选择后将新的PRACH频域位置告知对方小区，当对方小区获得优先选择小区最新的PRACH频域位置后，结合当前本小区的干扰位置选择新的PRACH频域位置。If the local cell A and the neighboring cell B detect interference at the same time and trigger the anti-interference process, each makes the current PRACH frequency domain position invalid, and notifies the other cell, and selects the one with the larger PCI of the two cells to prioritize the frequency domain Position selection, after selection, inform the opposite cell of the new PRACH frequency domain position. When the opposite cell obtains the latest PRACH frequency domain position of the preferred cell, select a new PRACH frequency domain position based on the current interference position of the own cell.
所述本小区A根据获取到的邻小区B的PRACH配置索引及频偏计算邻小区B的PRACH时频位置，具体方法如下：The cell A calculates the PRACH time-frequency position of the adjacent cell B according to the obtained PRACH configuration index and frequency offset of the adjacent cell B, and the specific method is as follows:
若B小区的PCI小于A小区的PCI，则先计算B小区的新的PRACH频域偏移，B小区的PRACH时域位置取决于PRACH配置索引，通过查3GPP协议的表确认B小区的PRACH接收的时域子帧；B小区通过当前B小区测量的上行IOT获得当前上行干扰情况，通过判断IOT和B小区当前配置的PRACH频域偏移，确认当前B小区的PRACH频域位置是否可用；若可用，则不用调整B小区的PRACH频域偏移，将该参数通知A小区即可；若干扰和PRACH频域位置重叠，即当前配置的B小区的PRACH频域偏移不可用，则进行调整：选择IOT低于门限的连续的6个PRB长度的频域位置，作为B小区新的PRACH频域位置的，将此时的PRACH频域偏移值通知A小区，A小区据此选择使用的PRACH频域位置，根据PRACH频域位置获得PRACH频域偏移。If the PCI of cell B is smaller than the PCI of cell A, first calculate the new PRACH frequency domain offset of cell B. The PRACH time domain position of cell B depends on the PRACH configuration index, and confirm the PRACH reception of cell B by checking the 3GPP protocol table. The B cell obtains the current uplink interference situation through the uplink IOT measured by the current B cell, and confirms whether the PRACH frequency domain position of the current B cell is available by judging the IOT and the PRACH frequency domain offset currently configured by the B cell; if If available, there is no need to adjust the PRACH frequency domain offset of B cell, just inform A cell of this parameter; if the interference overlaps with the PRACH frequency domain position, that is, the currently configured PRACH frequency domain offset of B cell is not available, then adjust : Select the frequency domain positions of 6 consecutive PRB lengths whose IOT is lower than the threshold, as the new PRACH frequency domain position of B cell, notify the A cell of the PRACH frequency domain offset value at this time, and the A cell selects the used one accordingly The PRACH frequency domain position, obtaining the PRACH frequency domain offset according to the PRACH frequency domain position.
所述本小区A在进行PRACH调整之前先将本小区A的PRACH频偏设置为无效值，用于标志本小区A即将进行prach调整。Before performing PRACH adjustment, the local cell A first sets the PRACH frequency offset of the local cell A to an invalid value, which is used to indicate that the local cell A is about to perform prach adjustment.
与现有技术相比，本发明具有以下有益效果：Compared with the prior art, the present invention has the following beneficial effects:
此项发明在现有技术的基础上加入了prach抗干扰调整时的邻小区间联合检测，不仅根据干扰情况，也结合了邻小区的prach当前配置来进行本小区的prach调整，有效地避免了当区域内存在相同干扰时，不同小区在进行prach抗干扰调整后发生prach资源碰撞进而导致prach虚检和漏检的问题。On the basis of the existing technology, this invention adds the joint detection between adjacent cells during the prach anti-interference adjustment, not only according to the interference situation, but also combines the current configuration of the prach of the adjacent cell to carry out the prach adjustment of the cell, effectively avoiding the When the same interference exists in the area, prach resource collision occurs in different cells after prach anti-interference adjustment, which leads to the problem of false detection and missed detection of prach.
即便相邻小区无法从时域上避开prach位置，且覆盖区域大范围存在同一种干扰时，也能够有效地实现prach抗干扰，避免自动调整后造成prach资源碰撞的情况。Even if adjacent cells cannot avoid the prach position in the time domain, and the same interference exists in a large area of the coverage area, the prach anti-interference can be effectively implemented to avoid the situation of prach resource collision after automatic adjustment.
有效提升干扰状态下各小区的终端接入成功率，保证了网络接入成功率，同时降低了各小区之间的PRACH的虚检概率，降低了各小区之间PRACH所在频域的干扰，保证了网络的稳定性。Effectively improve the terminal access success rate of each cell in the interference state, ensure the network access success rate, reduce the false detection probability of PRACH between cells, reduce the interference in the frequency domain of PRACH between cells, and ensure network stability.

具体实施方式detailed description
下面结合附图对本发明作进一步详细说明。The present invention will be described in further detail below in conjunction with the accompanying drawings.
参见图1，一种prach抗干扰技术中支持小区间联合检测的方法，具体实施步骤如下：Referring to Figure 1, a method for supporting inter-cell joint detection in a prach anti-interference technology, the specific implementation steps are as follows:
由于小区间的底噪检测定时器的启动时间和长度都可能不同，所以当覆盖范围内存在干扰时，不同的小区开始PRACH抗干扰的时间也可能不同，下面分几种情况来进行介绍：Since the starting time and length of the noise floor detection timer between cells may be different, when there is interference in the coverage area, the time for starting PRACH anti-interference in different cells may also be different. The following introduces several situations:
当A小区的干扰位置为[X,Y],A小区的PRACH频域位置为[M,N],干扰位置包含PRACH频域位置，此时A小区需要调整PRACH的频域位置，同时，由于邻小区B还未检测到干扰，邻小区B的尚未进行PRACH频域的抗干扰，所以此时邻小区B的PRACH是有干扰的，故此时本小区A获得了邻小区B的PRACH频域位置[P,Q],且两个小区的PRACH位置不重叠，此时A小区需要在频域干扰[X,Y]和邻小区B的PRACH频域位置[P,Q]之外的频域位置找到A小区可用的新的PRACH位置。When the interference position of A cell is [X, Y], the PRACH frequency domain position of A cell is [M, N], and the interference position includes the PRACH frequency domain position, then A cell needs to adjust the PRACH frequency domain position. At the same time, because Neighboring cell B has not detected interference, and neighboring cell B has not yet performed PRACH frequency domain anti-interference, so at this time the PRACH of neighboring cell B has interference, so this cell A has obtained the PRACH frequency domain position of neighboring cell B [P, Q], and the PRACH positions of the two cells do not overlap. At this time, cell A needs to interfere in the frequency domain [X, Y] and a frequency domain position other than the PRACH frequency domain position [P, Q] of neighboring cell B Find a new PRACH location available for cell A.
当A小区的干扰位置为[X,Y],A小区的PRACH频域位置为[M,N],干扰位置包含PRACH频域位置，此时A小区需要调整PRACH的频域位置，同时，由于邻小区B此时已经做完PRACH频偏调整，即B小区已完成PRACH频域的抗干扰，从原邻小区B的PRACH频域位置[P,Q]更新到[U,V]，邻小区B的PRACH已在干扰区域之外，此时A小区获得了邻小区B最新的PRACH频域位置[U,V],A小区为了保证两个小区的PRACH位置不重叠，此时A小区需要在频域干扰[X,Y]和邻小区B的PRACH频域位置[[U,V]之外的频域位置找到A小区可用的新的PRACH位置。When the interference position of A cell is [X, Y], the PRACH frequency domain position of A cell is [M, N], and the interference position includes the PRACH frequency domain position, then A cell needs to adjust the PRACH frequency domain position. At the same time, because The adjacent cell B has completed the PRACH frequency offset adjustment at this time, that is, the B cell has completed the anti-interference of the PRACH frequency domain, and the PRACH frequency domain position [P, Q] of the original adjacent cell B is updated to [U, V]. The PRACH of B is already outside the interference area. At this time, cell A has obtained the latest PRACH frequency domain position [U, V] of neighboring cell B. In order to ensure that the PRACH positions of the two cells do not overlap, cell A needs to be in the Find a new PRACH position available to cell A based on the frequency domain interference [X, Y] and the frequency domain position [[U, V] of the PRACH frequency domain position of the neighboring cell B.
当A小区的干扰位置为[X,Y],A小区的PRACH频域位置为[M,N],干扰位置包含PRACH频域位置，此时A小区需要调整PRACH的频域位置，同时，当邻小区B的干扰位置[S,T],邻小区B的PRACH频域位置[P,Q],干扰位置包含PRACH频域位置，此时邻小区B需要调整PRACH的频域位置。When the interference position of A cell is [X, Y], the PRACH frequency domain position of A cell is [M, N], and the interference position includes the PRACH frequency domain position, then A cell needs to adjust the PRACH frequency domain position. At the same time, when The interference position [S, T] of the adjacent cell B, the PRACH frequency domain position [P, Q] of the adjacent cell B, the interference position includes the PRACH frequency domain position, and the adjacent cell B needs to adjust the PRACH frequency domain position.
当两个小区同时进行PRACH抗干扰时，各自将当前PRACH的频域位置置为无效，并通知给对方小区，两个小区各自从去掉各自干扰和对方无效PRACH的频域位置进行新的PRACH频域位置选择。由于获得到的对方配置为无效值，表明对方也即将进行调整，所以此时先调整的一方不需要考虑对方的配置，仅根据干扰情况进行调整即可。When the two cells perform PRACH anti-interference at the same time, each will set the current PRACH frequency domain position as invalid, and notify the other cell, and the two cells will perform a new PRACH frequency from the frequency domain position where the respective interference and the other party's invalid PRACH have been removed. Domain location selection. Since the acquired configuration of the other party is an invalid value, it indicates that the other party is about to make adjustments, so the party who adjusts first does not need to consider the configuration of the other party at this time, and only needs to adjust according to the interference situation.
由于两个小区任何一方先调整都可行，且在网络规划时会尽量避免相邻小区的PCI相同，所以选取两个小区中PCI较大的一方优先调整，而PCI较小的一方待对方调整完成后再次触发一遍该流程即可。此时，由于B小区的PCI小于A小区的PCI，则先计算B小区的新的PRACH频域偏移，B小区的PRACH时域位置取决于PRACH配置索引，通过查3GPP协议的表可以确认B小区的PRACH接收的时域子帧；B小区通过当前B小区测量的上行IOT，可以获得当前上行干扰情况，通过判断IOT和B小区当前配置的PRACH频域偏移，确认当前B小区的PRACH频域位置和干扰重叠，即当前配置的B小区的PRACH频域偏移不可用，则进行调整：选择IOT低于门限的连续的6个PRB长度的频域位置，作为B小区新的PRACH频域位置的，将此时的新的PRACH频域位置[E,F]通知A小区，当A小区获得B小区最新的PRACH频域位置后，结合当前A小区的干扰位置，选择新的PRACH频域位置。Since either of the two cells can be adjusted first, and the PCI of adjacent cells will be avoided as far as possible during network planning, the one with the larger PCI is selected as the priority for adjustment, and the one with the smaller PCI waits for the other to complete the adjustment. Then trigger the process again. At this time, since the PCI of cell B is smaller than the PCI of cell A, the new PRACH frequency domain offset of cell B is calculated first, and the PRACH time domain position of cell B depends on the PRACH configuration index, and the B The time domain subframe received by the PRACH of the cell; the B cell can obtain the current uplink interference situation through the uplink IOT measured by the current B cell, and confirm the PRACH frequency of the current B cell by judging the IOT and the PRACH frequency domain offset currently configured by the B cell. The domain position and interference overlap, that is, the PRACH frequency domain offset of the currently configured B cell is not available, then adjust: select the frequency domain position of 6 consecutive PRB lengths whose IOT is lower than the threshold, as the new PRACH frequency domain of the B cell location, notify cell A of the new PRACH frequency domain position [E, F] at this time, and when cell A obtains the latest PRACH frequency domain position of cell B, it selects a new PRACH frequency domain based on the current interference position of cell A Location.
LTE频域带宽根据子载波带宽划分，然后根据频域每连续12子载波和7个时域符号定位一个PRB，这样20MHz频域带宽就定义为100个有效PRB，PRB从低频开始编号，为0-99。The LTE frequency domain bandwidth is divided according to the subcarrier bandwidth, and then a PRB is located for every 12 consecutive subcarriers and 7 time domain symbols in the frequency domain, so that the 20MHz frequency domain bandwidth is defined as 100 effective PRBs, and the PRBs are numbered from the low frequency, which is 0 -99.
PRACH接收位置就是：从0开始，经过PRACH频域偏移后的PRB开始的连续6个PRB。例如频域偏移值为15，则从0PRB开始，到14PRB(就是从1开始数的15)都是偏移范围，从15PRB开始的PRB就是PRACH频域位置开始的PRB。The PRACH receiving position is: starting from 0, 6 consecutive PRBs starting from the PRB after the PRACH frequency domain offset. For example, if the frequency domain offset value is 15, the offset range starts from 0 PRB to 14 PRB (that is, 15 starting from 1), and the PRB starting from 15 PRB is the PRB starting from the PRACH frequency domain position.
该场景中通过先将PRACH配置置为无效值以避免两个小区都同时获取到对方调整之前的值，造成双方调整到同一位置的情况。In this scenario, the PRACH configuration is first set to an invalid value to prevent both cells from obtaining the value before the adjustment of the other side at the same time, causing the two cells to adjust to the same position.
