Description

一种覆盖模式识别方法以及装置 技术领域
本发明涉及通信领域，尤其涉及一种覆盖模式识别方法以及装置。
背景技术
MF(MulteFire)系统是一种独立工作于非授权频谱的无线通信系统，目前已经完成了Release 1.0的标准化工作。通过MF系统的部署，各种运营商、服务提供商可以不受频谱的约束，在非授权频谱上独立、灵活得部署公用或者私用的无线网络来提供各种类型的无线网络服务。
当MF系统部署于港口、码头、自动化生产流等场景时，由于用户设备普遍具有较高的移动性，在用户设备的移动过程中，基站发送的无线信号容易被用户设备和基站之间各种物体遮挡，从而导致无线信号质量较差，用户设备可能无法正常接收；另一方面，由于用户设备数量较大，在移动过程中，也容易发生互相遮挡无线信号的情况，也会导致用户设备可能无法正常接收基站发送的数据。此时，对基站下发的信号质量有较高需求，需要基站提供更好的无线覆盖能力来应对无线信号质量较差的场景。
当下，长期演进技术LTE中的R12/13标准中，引入了“增强覆盖模式”，对不同的覆盖模式行了分级。为了对接入小区的终端所需的覆盖模式进行区分识别，对信道资源进行了统一规划，分别映射不同的覆盖模式。通过终端占用的资源来区分终端所处的覆盖模式，不同的覆盖模式从而对不同信号覆盖模式的终端进行不同的处理。
然而，在LTE的R12/13标准中，不同覆盖模式对应的信道资源不能复用，必须对资源进行了分组和规划，严格区分出不同覆盖模式集合分组，从而引起较高的资源占用。
发明内容
本发明实施例提供了一种覆盖模式识别方法以及装置，用于基站根据前导序列识别终端的覆盖模式。
有鉴于此，本申请第一方面提供了一种覆盖模式识别方法，该方法包括：
终端确定第一覆盖模式，可选的，该第一覆盖模式为增强覆盖模式或正常覆盖模式。具体的该终端接收该基站发送的参考信号接收功率预置范围；该终端检测来自该基站的信号的参考信号接收功率；若该参考信号接收功率在该参考信号接收功率预置范围之内，则该终端确定该第一覆盖模式为该正常覆盖模式；或者，若该参考信号接收功率不在该参考信号接收功率预置范围之内，则该终端确定该第一覆盖模式为该增强覆盖模式。参考信号接收功率预置范围可以包括一个阈值，大于等于或者大于该阈值，被认为是在该参考信号接收功率预置范围之内，若相反，则可以认为不在该参考信号接收功率预置范围之内，如该阈值为a，则大于等于a的均为在该该参考信号接收功率预置范围内，小于a的均不在该参考信号接收功率预置范围之内；或者，大于a的均为在该该参考信号接收功率预置范围内，小于等于a的均不在该参考信号接收功率预置范围之内，此处不做限定。该参考信号 接收功率预置范围被终端用于确定需要的第一覆盖模式，则该终端可以首先检测来自该基站的信号的参考信号接收功率(Reference Signal Receiving Power，RSRP)。需要说明的是，该终端接收该参考信号接收功率预置范围和检测来自该基站的信号的参考信号接收功率之间没有时序关系，即该终端接收该参考信号接收功率预置范围可以在检测来自该基站的信号的参考信号接收功率之前，也可以在之后，此处不做限定。
该终端根据该第一覆盖模式确定前导序列。具体的，为与LTE实现对齐，MF系统只对前导序列中的前64个进行了定义，对64个之后的这些前导序列，我们称之为“冗余”的前导序列，在此，可以把标准上没有定义的这些前导序列定义为“增强覆盖用户”使用的前导序列，可以使基站在用户接入过程中对用户的“增强覆盖模式”进行识别区分。

在本发明实施例中，该基站根据该前导序列识别该终端所需要的该第一覆盖模式，而不需要通过接收终端信号的信道来判断，因此信道资源可以被复用，从而降低资源的消耗。

具体实施方式
本发明实施例提供了一种覆盖模式识别方法以及装置，用于基站根据前导序列识别终端的覆盖模式。
为了使本技术领域的人员更好地理解本发明实施例方案，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的实施例，而不是全部的实施例。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参考图1，为本申请实施例中的通信系统架构，包括基站和终端。
在本申请实施例中，基站即公用移动通信基站是无线电台站的一种形式，是指在一定的无线电覆盖区中，通过移动通信交换中心，与移动电话终端之间进行信息传递的无线电收发信电台。
在本申请实施例中，终端可以为包括手机、平板电脑、PDA(Personal Digital Assistant，个人数字助理)、POS(Point of Sales，销售终端)、车载电脑等任意终端设备。以手机为例对终端的构造进行说明，包括：射频(Radio Frequency，RF)电路、存储器、输入单元、 显示单元、传感器、音频电路、无线保真(wireless fidelity，WiFi)模块、处理器、以及电源等部件。本领域技术人员可以理解，该部分手机结构并不构成对手机的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
在本申请实施例中，一个基站可以服务一个或多个小区，所谓小区也称蜂窝小区，是指在蜂窝移动通信系统中，同一个基站所覆盖的区域，在这个区域内终端可以通过无线信道与基站进行通信。在一些可行的实施例中，该小区也可以为一个扇区，此处不作限定。
当该通信系统用于港口、码头、自动化生产流等场景时，由于用户设备普遍具有较高的移动性，在用户设备的移动过程中，基站发送的无线信号容易被用户设备和基站之间各种物体遮挡，从而导致无线信号质量较差，或者由于用户设备数量较大，在移动过程中，也容易发生互相遮挡无线信号的情况，则会导致用户设备可能无法正常接收基站发送的数据。此时，对基站下发的信号质量有较高需求，需要基站提供更好的无线覆盖能力来应对无线信号质量较差的场景。
为了应对这样的场景，存在许多不同的“覆盖模式”的场景，需要基站能够及时的识别出终端所需的“覆盖模式”，从而进行不同的处理，更好的为小区用户服务，因此引入“增强覆盖模式”，对不同的信号覆盖能力进行了分级。为了对接入小区的终端所需的信号覆盖能力进行区分识别，对信道资源进行了统一规划，分别映射不同的覆盖模式，通过终端占用的资源来区分终端所处的覆盖模式，不同的覆盖模式从而对不同覆盖模式的终端进行不同的处理。然而，这种方法下，不同覆盖模式对应的信道资源不能复用，而必须对资源进行了分组和规划，严格区分出不同覆盖模式集合分组，因此降低了信道资源的利用率，而且增加了对信道资源调度的复杂度。
因此，本发明通过终端确定第一覆盖模式，该终端根据该第一覆盖模式确定前导序列，该终端向基站发送该前导序列，该前导序列的索引号用于指示该第一覆盖模式，由于基站仅需通过终端发送的前导序列就可以判断其覆盖模式，而不需要通过接收终端信号的信道来判断，因此不需要必须对资源进行了分组和规划，也不需要严格区分出不同覆盖模式集合分组，因此信道资源可以被复用，从而提高了信道资源的利用率，而且降低了对信道资源调度的复杂度。
为便于理解，下面对本申请实施例中的具体流程进行描述，请参阅图2，本申请实施例中覆盖模式识别方法一个实施例包括：
201、终端确定第一覆盖模式。
在本发明实施例中，终端和基站进行通信前，可以首先实现同步。具体的，终端首先搜索主同步信号(Primary Synchronization Signal，PSS)和/或辅同步信号(Secondary Synchronization Signal，SSS)，接着进行主信息块(Master Information Block，MIB)和/或系统信息块(System Information Blocks，SIB)解析，直至实现了终端和基站的连接和交互信息，以使得当终端处于基站的服务范围内时，终端可以得到基站的服务。
在本发明实施例中，当基站在服务的范围内发送广播信号，当终端接收到基站的广播信号时，可以根据接收到的广播信号的强弱确定自身所需要的第一覆盖模式，具体的第一覆盖模式可以为增强覆盖模式或正常覆盖模式。需要说明的是，第一覆盖模式还可以包括 等级1/2/3/4……不等，此处不做限定。在此，以第一覆盖模式为增强覆盖模式和正常覆盖模式为例进行说明。
在本发明实施例中，当终端需要确定自身的第一覆盖模式时，可以首先接收该基站发送的参考信号接收功率预置范围。需要说明的是，该参考信号接收功率预置范围可以为在终端和基站的同步过程中终端接收基站的，也可以为连接之后，基站主动发送给终端，也可以为当终端需要的时候，向基站发送请求获取的，此处不做限定。另外，参考信号接收功率预置范围可以包括一个阈值，大于等于或者大于该阈值，被认为是在该参考信号接收功率预置范围之内，若相反，则可以认为不在该参考信号接收功率预置范围之内，如该阈值为a，则大于等于a的均为在该该参考信号接收功率预置范围内，小于a的均不在该参考信号接收功率预置范围之内；或者，大于a的均为在该该参考信号接收功率预置范围内，小于等于a的均不在该参考信号接收功率预置范围之内，此处不做限定。
在另一些可行的实施例中，参考信号接收功率预置范围也可以为两个值，如a和b，则若处于(a，b)或(a，b]或[a，b)或[a，b]，则可以认为在参考信号接收功率预置范围内，否则可以认为不在该参考信号接收功率预置范围内，此处不做限定。
该参考信号接收功率预置范围被终端用于确定需要的第一覆盖模式，则该终端可以首先检测来自该基站的信号的参考信号接收功率(Reference Signal Receiving Power，RSRP)。需要说明的是，该终端接收该参考信号接收功率预置范围和检测来自该基站的信号的参考信号接收功率之间没有时序关系，即该终端接收该参考信号接收功率预置范围可以在检测来自该基站的信号的参考信号接收功率之前，也可以在之后，此处不做限定。
需要说明的是，RSRP是LTE以及MF系统中可以代表无线信号强度的关键参数以及物理层测量需求之一，是在某个符号内承载参考信号的所有资源粒子上接收到的信号功率的平均值。
在本发明实施例中，以第一覆盖模式为增强覆盖模式和正常覆盖模式为例，可以认为若该参考信号接收功率在该参考信号接收功率预置范围之内，则该终端确定该第一覆盖模式为该正常覆盖模式，若该参考信号接收功率不在该参考信号接收功率预置范围之内，则该终端确定该第一覆盖模式为该增强覆盖模式。
202、该终端根据该第一覆盖模式确定前导序列。
在本发明实施例中，当终端确定了该第一覆盖模式后，可以根据该第一覆盖模式确定对应的前导序列。
在一些可行的实施例中，可以预先定义了一个“根序列”，用于支持一定数量的使用前导序列的用户(以下称前导序列用户)，需要说明的是，前导序列格式与占用的信道资源(Interlace)、根序列、正交掩码(orthogonal cover code,OCC)和循环偏移参数(Ncs)相关。
需要说明的是，“根序列”为用于生成前导序列的序列。Interlace为MF系统上行资源的分配单位，一个Interlace包含10个PRB(physical resource block)，并且10个PRB在系统带宽上均匀分布。以20MHz，100PRB为例，Interlace 0包含10个PRB，即PRB 0，PRB10，PRB20，…PRB 90；Interlace 1包含10个PRB，为PRB1，PRB11，PRB21，…，PRB91。 OCC、Ncs分别用于对根序列进行加掩和循环偏移操作，生成不同的前导序列。在MF系统中，可用的OCC有4种，循环偏移可用的种类根据Ncs的配置计算：12/Ncs。
在本发明实施例中，当定义了Ncs后，可以定义一个“根序列”占用一个Interlace能够支持的前导序列用户的个数为：4*12/Ncs。若在Interlace的资源不受限的情况下增加Interlace，Interlace资源受限的情况，通过增加新的“根序列”直到能支持64个用户。
在一些可行的实施中，不同Ncs、Interlace配置下所需的根序列个数和能够支持的前导序列的个数见下表：
Figure PCTCN2017081151-appb-000001
为与LTE实现对齐，MF系统只对前导序列中的前64个进行了定义。如上表所示，在Ncs＝1/2/4的配置下，所支持的前导序列用户个数已经大于64(96/72/70)，但是标准只对前64个进行了定义，对64个之后的这些前导序列，我们称之为“冗余”的前导序列，在目前的标准中没有定义。其中，当Interlace为1时，Ncs＝1/2/4，则冗余前导序列个数分别为：32/8/6；当Interlace为2时：Ncs＝1/2/4，则冗余前导序列用户为：32/8/8；其他Ncs配置下，前导序列冗余用户个数都为0。在此，可以把标准上没有定义的这些前导序列定义为“增强覆盖用户”使用的前导序列，可以使基站在用户接入过程中对用户的“增强覆盖模式”进行识别区分。具体的，请参考下表：
Figure PCTCN2017081151-appb-000002
系统配置Interlace个数为2的情况下：
Figure PCTCN2017081151-appb-000003
通过这种方式我们利用定义的Interlace和相应的根指数定义了分别支持“正常覆盖模式”和“增强覆盖模式”的前导序列。需要说明的是，该前导序列对应于一索引号，该前导序列与索引号的对应关系是预先配置的，或者基站通过广播信道通知终端的，其中该预先配置是在标准或协议中规定的，具体的，该前导序列的索引号用于确定该第一覆盖模式。
在本发明实施例中，当终端需要正常覆盖模式时，可以选择索引号为0～63的前导序列中作为前导序列组，当终端需要增强覆盖模式且Ncs为1时，可以选择索引号为64～95的前导序列中作为前导序列组。需要说明的是，根据上表，当Ncs为3/6/12时，Interlace个数为2的情况下，可以支持的前导序列用户的个数为64个，因此不存在冗余用户，因此在这种情况下不支持“增强覆盖模式”的前导序列。则终端可以从该前导序列集合中选择一个作为该前导序列。
在上述表格的例子中，由于在Ncs＝1/2/4的情况下才有冗余的前导序列用来作为“增强覆盖模式”的用户使用，因此收到很大的约束。因此，在另一些可行的实施例中，为了改善这种个情况，可以对每种Ncs配置，使得其支持的前导序列支持的用户个数全部扩展到96个，请参下表：
Figure PCTCN2017081151-appb-000004
除了Ncs＝1外，其他的各种Ncs＝2/3/4/6/12都导致了使用“根序列个数”增加。Ncs＝2/3/4/6/12在系统配置Interlace个数为1的情况下，增加使用的“根序列”分别为1/2/3/2/8,在系统配置Interlace个数为2的情况下，增加使用的“根序列”分别为0/1/1/2/4。
在所有的Ncs配置情况前导序列所对应的第一覆盖模式，见下表：
Figure PCTCN2017081151-appb-000005
这样的话，即可在Ncs在所有可能取值的情况下，都存在冗余的前导序列，以支持“增强覆盖模式”的前导序列用户使用。
需说明的是，定义了一个“根序列”的方法不仅以上两种，还可以有其他的方法，只要能生成冗余的前导序列以支持“增强覆盖模式”的前导序列用户，此处不做限定。
在一些可行的实施例中，终端不仅可以从预置的协议中根据第一覆盖模式确定对应的前导序列，也可以接收基站广播的系统信息，然后根据该系统信息和第一覆盖模式确定前导序列，此处不做限定。
比如，系统信息中可以携带如下信息来指示“增强覆盖模式”所对应的前导序列组：
