物理小区标识配置、 逻辑根序列索引配置方法及基站设备
本申请要求于 2012 年 2 月 24 日提交中国专利局、 申请号为 201210043556.X, 发明名称为"物理小区标识配置、 逻辑根序列索引配置方 法及基站设备 "的中国专利申请的优先权， 其全部内容通过引用结合在本申 请中。 技术领域
本发明涉及通信技术领域， 具体涉及一种物理小区标识配置、 逻辑根 序列索引配置方法及基站设备，应用于长期演进（ Long Term Evolution, LTE ) ***。
背景技术 在 LTE***中， 为了提高频谱利用率， 一般釆用同频组网方式， 即相 邻小区间频率完全复用。 在同频组网方式下， 相邻小区间存在较强的干扰， 这对基站的上行信道接收提出了挑战。 如何更好地抑制相邻小区间的干扰 以提高***性能， 是本领域研究的热点。
在 LTE ***中， 定义了物理上行共享信道（Physical Uplink Shared Channel, PUSCH ), 物理上行控制信道（ Physical Uplink Control Channel, PUCCH )， 物理随机接入信道（ Physical Random Access Channel, PRACH ) 以及探测参考信号（ Sounding Reference Signal, SRS )这四种上行信道。 其 中， PUSCH用于进行数据上行传输， PUCCH用于信令上行传输， PRACH 用于用户设备 ( User Equipment, UE )随机接入， SRS用于测量上行信道信 息。 目前， 业界对于相邻小区间的 PUSCH、 PUCCH, SRS之间的干扰抑制 已经有较多成熟的研究。 例如， 协议规定上述三种信道都可以由物理小区 标识 （Physical Cell ID, PCI ) 生成或者进行加扰， 通过合理规划相邻小区 的 PCI可以使得干扰随机化。 而对于 PUSCH、 PUCCH, SRS这三种信道和 PRACH之间的干扰抑制， 业界研究较少。 UE在 PRACH上发送的信号称 之为前导序列 （Preamble Sequence, Preamble ), 前导序列为 Zadoff-Chu序 列 （简称 ZC序列 ), 其长度为 839点， 前导序列可以有 838个， 前导序列 也称之为根序列 （Root Sequence, RS )。 不同前导序列由不同根序列索引 ( Root Sequence Index, RSI ) 决定， RSI取值范围可以为 1-838。 协议根据 不同 RS的特性， 可以将 RSI进行重新排列， 重新排列后的 RSI成为逻辑根 序列索引 （ Logic Root Sequence Index, LRSI ), 其编号可以为 0-837。
通过仿真发现， 当邻区的 PCI 和服务小区的 LRSI 满足关系 IN (PCI, LRSI) >1 ( IN (PCI, LRSI)表示邻区 SRS对服务小区的 PRACH检 测的千扰系数， 1表示干扰系数门限）时，邻区的 SRS对服务小区的 PRACH 检测影响较大， 容易造成基站对随机接入的误检， 从而导致随机接入虚警。 发明内容 本发明实施例提供了一种物理小区标识配置、 逻辑根序列索引配置方 法及基站， 用于减少随机接入虚警。

本发明实施例提供了一种物理小区标识配置、 逻辑根序列索引配置方 法及基站， 可以减少随机接入虚警。 以下分别进行详细说明。
实施例一：
请参阅图 1 ,图 1为本发明实施例提供的一种逻辑根序列索引配置方法 的流程图。 其中， 图 1所示的逻辑根序列索引配置方法可以应用于 LTE系 统、 增强型的 LTE***等， 本发明实施例不作限定。 如图 1所示， 该逻辑 根序列索引配置方法可以包括以下步骤：
101、从 LRSI占用表中依次搜索一处连续若千个未被邻区占用的 LRSI, 其中， 连续若干个未被邻区占用的 LRSI的个数与服务小区的 RS的个数相 同。
其中， 服务小区的 RS的个数可以根据服务小区的半径大小计算得到， 这是本领域技术人员公知的常识， 本发明实施例不作详细介绍。
本发明实施例后续将结合具体的实施例详细描述如何生成上述步骤 101中的 LRSI占用表。
102、以连续若干个未被邻区占用的 LRSI中的每一个 LRSI作为查找参 数， 从预设的干扰系数表中查找出每一个 LRSI对应的若干个干扰系数， 其 中， 干扰系数表中记录了在给定邻区 PCI和上述每一个 LRSI的条件下， 邻 区的 SRS对服务小区的 PRACH检测的千扰系数。
本发明实施例后续将结合具体的实施例详细描述上述步骤 102 中的干 扰系数表的形式。
103、 若上述的连续若干个未被邻区占用的 LRSI对应的所有千扰系数 中不存在大于干扰系数门限的干扰系数， 则输出上述的连续若干个未被邻 区占用的 LRSI中的第一个 LRSI作为服务小区的起始 LRSI。
其中，若上述的连续若干个未被邻区占用的 LRSI对应的所有千扰系数 中不存在大于干扰系数门限的干扰系数， 则说明服务小区以上述的连续若 干个未被邻区占用的 LRSI中的第一个 LRSI作为初始 LRSI时， 不会存在 任意一个邻区 SRS对服务小区 PRACH检测造成影响 , 不会引起服务小区 的随机接入虚警。
本发明实施例一中，在配置服务小区 LRSI时，考虑了邻区 PCI的影响， 以使在给定邻区 PCI和连续若干个未被邻区占用的 LRSI中的每一个 LRSI 的条件下， 邻区 SRS对服务小区 PRACH检测的所有干扰系数中不大于干 扰系数门限的干扰系数。 从而， 可以降低邻区 SRS对服务小区 PRACH检 测的影响， 减少服务小区 PRACH的误检， 减少服务小区的随机接入虚警。
实施例二：
请参阅图 2 ,图 2为本发明实施例提供的另一种逻辑根序列索引配置方 法的流程图。 其中， 本发明实施例二是以 LTE***为例， 从服务小区基站 的角度来介绍本发明实施例提供的逻辑根序列索引配置方法的。 如图 2 所 示 , 该逻辑根序列索引配置方法可以包括以下步骤：
201、服务小区基站导入邻区的 LRSI列表，遍历邻区的 LRSI列表生成 LRSI占用表 LRSI— MASK。
其中， 服务小区基站可以先根据服务小区的半径大小计算出服务小区 需要多少个 RS, 从而可以获悉服务小区需要多少个 LRSI。
假设服务小区需要 P ( P≥l )个 LRSI, 服务小区基站导入的邻区 LRSI 列表 LRS— TBL是两维数组， 第一维代表邻区索引， 第二维代表邻区 LRSI 索引。 £设共有 N个邻区， 邻区 LRSI 个数组成数组 M, 那么遍历邻区 LRS_TBL, 服务小区基站即可生成 LRSI占用表 LRSI_MASK。 作为一种可 选的实施方式， 服务小区基站可以采用以下软件程序来生成 LRSI 占用表 LRSI_MASK, 即：
for i = 0; K 838; ι++
LRSI— MASK ( ι ) = 0
end
for i = 0; i < N; i ++
forj=0; j<M ( l ); j++
LRSI— MASK ( LRS— TBL ( ι ) ( j ) ) = 1 ;
end
end
本发明实施例中， 服务小区基站可以根据物理距离、 天线覆盖方向等 参数确定邻区。
202、 服务小区基站从 LRSI占用表 LRSI_MASK中依次搜索一处连续 P个未被邻区占用的 LRSI, 并获取连续 P个未被邻区占用的 LRSI中的每 一个 LRSI。
作为一种可选的实施方式， 服务小区基站可以采用以下软件程序来依 次搜索一处连续 P个未被邻区占用的 LRSI, 并获取连续 P个未被邻区占用 的 LRSI中的每一个 LRSI, 即：
for i = 0; i < 838; i++

break
end
end
L SI Output = i;
break;
end end
203、服务小区基站以连续 P个未被邻区占用的 LRSI中的每一个 LRSI 作为查找参数， 从预设的干扰系数表中查找出每一个 LRSI 对应的干扰系 数， 其中， 干扰系数表中记录了在给定邻区的 PCI和上述每一个 LRSI的条 件下， 邻区 SRS对服务小区的 PRACH检测的干扰系数。
本发明实施例中， 根据仿真实验可以得出如表 1 所示的干扰系数表， 其中，该干扰系数表中记录了在给定邻区 PCI和上述每一个 LRSI的条件下， 邻区 SRS对服务小区 PRACH检测的干扰系数。 其中， 给定邻区 PCI的取 值范围可以是 0~503。 LRSI的取值范围可以是 0~837。 表 1中， IN (x, y) 代表在给定邻区 PCI为 X,每一个 LRSI为 y时，邻区 SRS对服务小区 PRACH 检测的干扰系数。 通过仿真实验可知， 当 0 IN ( X, y) <1 时， 邻区 SRS 对服务小区 PRACH检测的影响比较小 ,服务小区基站不会产生随机接入虚 警； 而当 IN ( X, y ) >1时， 邻区 SRS对服务小区 PRACH检测的影响比较 大， 服务小区基站将产生随机接入虚警。 其中， 1表示邻区 SRS对服务小 区 PRACH检测的干扰系数门限。 根据实际需求， 邻区 SRS 对服务小区 PRACH检测的干扰系数门限也可以设置为其他数值， 本发明实施例不作限 定。
表 1
Figure imgf000010_0001
举例来说，假设连续 Ρ个未被邻区占用的 LRSI中的第一个 LRSI为 0, 那么服务小区基站可以将" LRSI=0"作为查找参数， 从表 1 所示的干扰系数 表中可以查找出与" LRSI=0"对应的干扰系数 I (0, 0)、 IN( 1, 0)、 IN(2, 0) ...... IN ( 503, 0 )。 再举例来说， 假设连续 P 个未被邻区占用的 LRSI 中的另一个 LRSI为 1 , 那么可以将" LRSI=1"作为查找参数， 从表 1所示的 干扰系数表中可以查找出与 "LRSI=1"对应的干扰系数 IN ( 0 , 1 )、 IN ( 1, 1 )、 IN (2, 1 ) ...... IN ( 503, 1 )。
204、 服务小区基站判断连续 P个未被邻区占用的 LRSI对应的所有干 扰系数中是否存在大于干扰系数门限的干扰系数，如果是，则执行步骤 205; 如果否， 则执行步骤 208, 并结束本流程。
其中，若连续 P个未被邻区占用的 LRSI对应的所有干扰系数中存在大 于千扰系数门限的干扰系数， 则说明服务小区以连续 P个未被邻区占用的 LRSI中的第一个 LRSI作为初始 LRSI时， 会存在至少一个邻区 SRS对服 务小区 PRACH检测造成影响， 可能导致服务小区的随机接入虚警。
205、 服务小区基站计算并记录连续 P个未被邻区占用的 LRSI对应的 所有千扰系数的累加和 , 并执行步骤 206。
206、 服务小区基站判断 LRSI 占用表是否搜索完毕， 如果否， 则返回 步骤 202; 如果是， 则执行步骤 207。
其中， 若步骤 206中服务小区基站判断出 LRSI占用表尚未搜索完毕， 那么服务小区基站可以返回步骤 202, 继续从 LRSI占用表中依次搜索下一 处连续 P个未被邻区占用的 LRSI。
207、 服务小区基站输出最小累加和对应的连续 P 个未被邻区占用的 LRSI中的第一个 LRSI作为服务小区的起始 LRSI, 并结束本流程。
举例来说， ^设一处连续 P个未被邻区占用的 LRSI中的一个 LRSI为 0, 并且服务小区基站将 "LRSI=0"作为查找参数， 从表 1所示的干扰系数表 中查找出与" LRSI=0，，对应的干扰系数 IN( 0, 0 )、 IN( 1, 0 )、 IN( 2, 0 ) ...... IN
( 503, 0 ), 但是与 "LRSI=0，，对应的所有干扰系数 IN (0, 0)、 IN ( 1, 0 )、 IN (2, 0) ...... IN ( 503, 0 ) 中至少有一个干扰系数大于干扰系数门限， 那么服务小区基站可以计算并记录这一处的连续 P个未被邻区占用的 LRSI 对应的所有干扰系数的累加和 S。 又假设下一处连续 P个未被邻区占用的 LRSI中的一个 LRSI为 836, 并且服务小区基站将 "LRSI=836，，作为查找参 数,从表 1所示的千扰系数表中查找出与" LRSI=836"对应的干扰系数 IN( 0, 836 )、 IN ( 1, 836 )、 IN (2, 836 ) ...... IN ( 503, 836 ), 但是与 "LRSI=836" 对应的所有干扰系数 IN (0， 836 )、 IN ( 1, 836 )、 IN (2, 836) ...... IN ( 503,
836 ) 中至少有一个干扰系数大于干扰系数门限， 那么服务小区基站可以计 算并记录这一处的连续 P个未被邻区占用的 LRSI对应的所有干扰系数的累 加和 S'; 如果 S，> S, 并且服务小区基站判断出 LRSI占用表已经搜索完 毕，那么服务小区基站可以将 S对应的连续 P个未被邻区占用的 LRSI中的 "LRSI=0"作为服务小区的起始 LRSI。 这样做可以最大程度地降低邻区 SRS 对服务 d、区 PRACH检测的影响， 从而减少服务小区 PRACH的误检， 减少 服务小区的随机接入虚警。
208、 服务小区基站输出连续 P 个未被邻区占用的 LRSI 中的第一个 LRSI作为服务小区的起始 LRSI, 并结束本流程。
本发明实施例二中， 服务小区基站在配置服务小区 LRSI时， 考虑了邻 区 PCI 的影响， 以使在给定邻区 PCI和连续若干个未被邻区占用的 LRSI 中的每一个 LRSI的条件下 ,邻区 SRS对服务小区 PRACH检测的所有干扰 系数中不大于干扰系数门限的千扰系数。 从而， 可以降低邻区 SRS对服务 小区 PRACH检测的影响， 从而减少服务小区 PRACH的误检， 减少服务小 区的随机接入虚警。
实施例三：
请参阅图 3 ,图 3为本发明实施例提供的一种物理小区标识配置方法的 流程图， 应用于 LTE***。 如图 3所示， 该物理小区标识配置方法可以包 括以下步骤：
301、 从 PCI占用表中依次搜索一个未被邻区占用的 PCI。
本发明实施例后续将结合具体的实施例详细描述如何生成上述步骤 301中的 PCI占用表。
302、 以未被邻区占用的 PCI作为查找参数， 从预设的干扰系数表中查 找出与未被部区占用的 PCI对应的若干个干扰系数， 其中， 该干扰系数表 中记录了在给定邻区 LRSI和未被邻区占用的 PCI条件下， 服务小区 SRS 对邻区 PRACH检测的干扰系数。
本发明实施例中， 上述步骤 302中的干扰系数表可以和表 1类似。 例 如， 假设上述步骤 301从 PCI 占用表中依次搜索一个未被邻区占用的 PCI 为 0, 那么可以将 "PCI=0" 作为查找参数， 从表 1所示的干扰系数表中查 找出与 "PCI=0"对应的干扰系数 IN ( 0, 0 )、 IN ( 0, 1 )、 IN ( 0, 2 ) ... ... IN ( 0, 837 )。
303、 若查找出的与未被邻区占用的 PCI对应的所有干扰系数中不存在 大于干扰系数门限的干扰系数， 则输出该未被邻区占用的 PCI作为服务小 区的 PCL
其中， 若查找出的与未被邻区占用的 PCI对应的所有干扰系数中不存 在大于干扰系数门限的干扰系数，则说明服务小区以该未被邻区占用的 PCI 作为服务小区的 PCI时， 不会存在服务小区 SRS对任意一个邻区 PRACH 检测造成影响， 不会引起任意一个邻区的随机接入虚警。
本发明实施例三中， 在配置服务小区的 PCI时， 考虑了邻区 LRSI的影 响， 以使在给定邻区 LRSI和未被邻区占用的 PCI条件下， 服务小区 SRS 对邻区 PRACH检测的干扰系数中不大于干扰系数门限的干扰系数。 从而 , 可以降低服务小区 SRS对邻区 PRACH检测的影响， 减少邻区 PRACH的 误检， 减少邻区的随机接入虚警。
实施例四：

401、 服务小区基站导入邻区 PCI列表， 并遍历邻区的 PCI 列表生成 PCI占用表 PCI— MASK。
其中， 服务小区基站导入的邻区 PCI列表 PCI_TBL是一维数组。 假设 共有 N个邻区， 那么服务小区基站可以采用以下软件程序来生成 PCI占用 表 PCI— MASK, 即：
for i = 0; K 504; i ++
PCI MASK(i) = 0
end
for i = 0; i < N; i ++
PCI_MASK(PCI_TBL (i)) = 1；
end 402、服务小区基站从 PCI占用表中依次搜索一个未被邻区占用的 PCI。 作为一种可选的实施方式，服务小区基站可以采用以下软件程序从 PCI 占用表 PCI— MASK中依次搜索一个未被邻区占用的 PCI, 即：
for 1 = 0; K 504; ι ++
if 0 == PCI— MASK(i)
PCI Output = i;
break;
end
end
403、 服务小区基站以该未被邻区占用的 PCI作为查找参数， 从预设的 干扰系数表中查找出与该未被邻区占用的 PCI对应的干扰系数， 其中， 该 干扰系数表中记录了在邻区 LRSI和该未被部区占用的 PCI条件下，服务小 区 SRS对邻区 PRACH检测的干扰系数。
404、服务小区基站查找出的与该未被邻区占用的 PCI对应的所有干扰 系数中是否存在大于干扰系数门限的干扰系数， 如果是， 则执行步骤 405; 如果否， 则执行步骤 408, 并结束本流程。
其中， 若查找出的与该未被邻区占用的 PCI对应的所有干扰系数中存 在大于干扰系数门限的干扰系数，则说明服务小区以该未被邻区占用的 PCI 作为其 PCI时， 会存在服务小区 SRS对至少一个邻区 PRACH检测造成影 响， 导致邻区的随机接入虚警。
405、服务小区基站计算并记录与该未被邻区占用的 PCI对应的所有干 扰系数的累加和 , 并执行步骤 406。
406、 服务小区基站判断 PCI占用表是否搜索完毕， 如果否， 则返回步 骤 402; 如果是， 则执行步骤 407。
其中， 若步骤 406中服务小区基站判断出 PCI 占用表尚未搜索完毕， 那么服务小区基站可以返回步骤 402,继续从 PCI占用表中依次搜索下一个 未被邻区占用的 PCI。
