Definitions
- the present disclosure relates to the field of communication technology, and in particular to a network system, cell access method, terminal, and network equipment.
- the reason why cellular networks are widely adopted is derived from a mathematical conclusion, that is to cover a plane with circles of the same radius, when the center of the circle is at the center of each regular hexagon of the regular hexagon grid, that is, when the center of the circle is at a regular triangle
- the number of circles used in the grid points is the least.
- the use of the least number of nodes can cover the largest area of the graph, even if the nodes are required to be on a grid with translational characteristics like a lattice, it is still an unknown problem to be solved, but in communication, the use of circles to express practical requirements is usually It is reasonable, so in consideration of saving equipment construction cost, regular triangular mesh or simple hexagonal mesh is the best choice.
- the network formed in this way is covered together and shaped very much like a honeycomb, so it is called a cellular network.
- a cell is defined as an area that provides users with wireless communication services, and is a basic unit of a wireless network.
- the number of cells supported by the base station is determined by "number of sectors x number of carrier frequencies per sector". In the 3 ⁇ 2 configuration, the entire circular area is divided into 3 sectors for coverage, and each sector uses 2 carrier frequencies, so there are a total of 6 cells. (But the maximum number of cells corresponding to a base station is more than 6).
- a cellular network cell corresponds to a physical cell ID and a global cell ID and a set of system messages.
- the system information broadcast is operated by the network. It is sent periodically or on demand.
- the terminal User Equipment, UE
- the system message includes the information of the cell.
- Physical Random Access Channel (PRACH) configuration index, logical root sequence initial value, cyclic shift index, uplink and downlink configuration index are equal to the parameters related to random access.
- PRACH Physical Random Access Channel
- the UE To access the gNB network, the UE must go through cell search, determine a serving cell, and then obtain the cell system information, initiate random access and other processes, so as to obtain frequency and symbol synchronization with a specific cell; 2) Obtain the system frame clock, That is, the starting position of the downlink frame; 3) Determine the physical-layer cell identity (PCI) of the cell.
- PCI physical-layer cell identity
- the UE not only needs to perform cell search when it is turned on, but to support mobility, the UE will constantly search for neighboring cells, obtain synchronization, and estimate the signal reception quality of the cell, so as to decide whether to perform handover (handover, when the UE is in RRC_CONNECTED State) cell selection and/or cell re-selection (cell re-selection, when the UE is in the RRC_IDLE state).
- handover when the UE is in RRC_CONNECTED State
- cell selection and/or cell re-selection cell re-selection, when the UE is in the RRC_IDLE state.
- the order of searching is cells with the same frequency, cells with different frequencies, and then cells between different systems.
- the terminal still needs to determine whether the signal quality of the cell meets certain requirements before it can further determine whether it can camp on the cell.
- the UE is handing over, it also selects a certain target cell for handover.
- Downlink interference The UAV receives a large number of neighboring cells in the air, and the number of neighboring cells is as many as a dozen, which causes the average downlink SINR to drop to about 0db.
- ISD 500m urban areas will receive 2.5km cells, frequent handovers in the air, handover failures and dropped calls are 2-5 times higher than the ground
- the path loss of the UAV up to multiple neighboring areas is close, which has a great impact on the interference of neighboring areas.
- the UAV's uplink to multiple surrounding base stations are all LOS paths, and the UAV terminal uplink service will interfere with the uplink performance of ground users in the surrounding neighboring areas.
- Traditional terrestrial UE power control only considers the path loss and SINR of the cell, and does not consider the interference to neighboring cells.
- the widely used cellular network is a flat cell, which has good service performance for traditional ground UEs.
- it is caused by its flight characteristics (flight speed and different flight altitude).
- Flight characteristics and propagation characteristics are different.
- the application of flat cells brings too much complexity to the service and handover of drones, and the management of access and neighboring cell relationships.

Abstract
本公开的实施例提供一种网络***、小区的接入方法、终端及网络设备。所述网络***包括:至少一个小区,所述小区为用户提供无线通信业务和/或信令控制,所述小区的覆盖区域包括至少一块可定义的立体区域。本公开的方案实现了小区的规划,为水域、陆域、空域三域一体的通讯提供基础的通信平台。
Description
相关申请的交叉引用
本申请主张在2019年8月22日在中国提交的中国专利申请号No.201910778514.2的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,特别是指一种网络***、小区的接入方法、终端及网络设备。
相关技术中,蜂窝网络被广泛采用的原因是源于一个数学结论,即以相同半径的圆形覆盖平面,当圆心处于正六边形网格的各正六边形中心,也就是当圆心处于正三角网格的格点时所用圆的数量最少。虽然使用最少结点可以覆盖最大面积的图形即使要求结点在一个如同晶格般有平移特性的网格上也仍是有待求解的未知问题,但在通讯中,使用圆形来表述实践要求通常是合理的,因此出于节约设备构建成本的考虑,正三角网格或者也称为简单六角网格是最好的选择。这样形成的网络覆盖在一起,形状非常像蜂窝,因此被称作蜂窝网络。
相关技术中,一个小区的定义是为用户提供无线通信业务的一片区域,是无线网络的基本组成单位。基站支持的小区数由“扇区数×每扇区载频数”确定。在3×2配置中,整个圆形区域分为3个扇区进行覆盖、每扇区使用2个载频,那么就一共有6个小区。(但一个基站对应的最大小区数不止6个)。
一个蜂窝网络小区对应一个物理小区标识和全局小区标识和一套***消息。***信息广播由网络实现操作,周期性发送或按需发送,终端(User Equipment,UE)开机后,会接收到由基站(gNB)发送的同步信号和***消息,其中***消息中包括本小区的物理随机接入信道(Physical Random Access Channel,PRACH)配置索引、逻辑根序列初始值、循环移位索引、上下行配置索引等于随机接入有关的参数。UE要接入gNB网络,必须经过小区搜索、 确定一个服务小区,然后获取该小区***信息、发起随机接入等过程,从而与某一个特定小区取得频率和符号同步;2)获取***帧时钟,即下行帧的起始位置;3)确定小区的物理层小区标识(Physical-layer Cell Identity,PCI)。
UE不仅需要在开机时进行小区搜索,为了支持移动性(mobility),UE会不停地搜索邻居小区、取得同步并估计该小区信号的接收质量,从而决定是否进行切换(handover,当UE处于RRC_CONNECTED态)小区选择和/或小区重选(cell re-selection,当UE处于RRC_IDLE态)。在小区搜索的时候,搜索的次序是同频小区、异频小区、然后找不同***之间的小区。在经过前面的小区搜索过程后,终端仍需判定该小区的信号质量是否达到一定的要求,才能进一步确定是否可以驻留在该小区。UE在切换的时候,也是选择确定的目标小区进行切换。
对于特定的UE,如无人机,飞行器,机械臂等会存在以下问题:
1)下行干扰:无人机在空中收到大量邻区,邻区个数多达十几个,导致下行平均SINR下降至0db左右。
2)移动性问题,部分干扰邻区来自远距离基站:ISD=500m城区场景会收到2.5km外小区,空中频繁切换,切换失败和掉线次数比地面高出2-5倍
3)无人机上行到多个邻区的路损接近,对邻区干扰影响大。无人机上行到周围多个基站都是LOS径,无人机终端上行业务会干扰周边邻区的地面用户上行性能。传统地面UE功控,只考虑本小区路损及SINR,不考虑对邻区的干扰。
相关技术中,被广泛采用的蜂窝网络是一个平面小区,对传统的地面UE服务性能很好,但是对于无人机这类特殊UE,由于它的飞行特性(飞行速度,飞行高度不同)导致的信道模型,传播特性不同,平面小区的应用对无人机的服务和对无人机的切换,接入和邻区关系的管理都带来太多的复杂度。

下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
如图1所示,本公开的实施例提供一种网络***,包括:至少一个小区,所述小区为用户提供无线通信业务和/或信令控制的覆盖区域是至少一块可定义的立体区域。
该实施例所述的网络***中,定义小区是为用户提供无线通信业务的一片立体区域,并不是相关技术中的一片扇区或者平面区域,所述小区由至少一个网络设备形成,所述网络设备包括基站、发射点、接收点、中央单元(central RAN unit)、分布单元(distributed RAN unit)、室内基带处理单元(BBU)、远 端射频单元(Radio Remote Unit,RRU)、中继、通信气球、飞行的飞行器基站、天线、卫星中的至少一种。这里的天线可以和其它设备一起使用,比如和基站一起使用,也可以作为独立设备使用。
可选的,所述立体区域的空间范围包括:至少一个空间网格,所述空间网格为在经度、纬度、高度三个维度上按照预设的间隔对球体进行递归剖分,对整个地球立体空间进行网格划分及编码后形成的剖分网。
也就是说,一个或多个基站、发射点、接收点、中央单元、分布单元、BBU、RRU、中继、通信气球、飞行的飞行器基站、天线、卫星中的至少一种会形成所述小区,或者叫立体小区,多个立体小区可以形成一个立体小区群。
一个立体小区可以由一个或多个空间网格,或者,空间网格群组成,并会关联一个或多个网格数组或者序列码组或者序列,一个立体小区也可以关联一个或者多个序列码组的索引号、空间网格群的序列和/或序列的索引号;
本公开的一可选实施例中,所述小区对应以下信息中的至少一项:
至少一个空间网格数组/序列码组/序列;
至少一个空间网格数组的索引号/序列码组的索引号/序列的索引号;
空间网格群的序列;
空间网格群的序列的索引号。
本公开的一可选实施例中,一个小区对应一个全局小区标号,这是一个高层为小区配置的小区标号。
可选的,所述空间网格为:空间网格应该对整个地球立体空间进行网格划分及编码。在经度、纬度、高度三个维度上按照一定的间隔对球体进行递归剖分,具有经纬一致性及正交性等优点。网格具有可标识、可定位、可索引、多尺度和自动空间关联等优点,可作为空间管控和大数据管理的空间参考框架。
空间网格的体元是多尺度的,并且每一尺度的体元均无缝、无叠充满着整个地球立体空间。
以GeoSOT为例,GeoSOT地球空间参考网格体系:被称为2n一维整型数组的全球等经纬度剖分网格***(Geographical coordinate global Subdivision grid with One-dimension-integer on Two to n-th power,简称GeoSOT)。
GeoSOT地球空间参考网格编码通常采用32位8进制数值,记录长度相当4个汉字,最多8个汉字(64位),第1~9位是度级网格编码,第10~15位是分级网格编码,第16~21是秒级网格编码,第22~32位是秒以下网格编码;编码长度表示网格层级,编码长度越长,网格越细;书写编码时,前面以G开头,度分秒级编码以“-”隔开,秒以下编码以“.”隔开,形式如下:Gddddddddd-mmmmmm-ssssss.uuuuuuuuuuu
并具备以下几个特点:
1)立体性。GeoSOT地球空间参考网格完整覆盖自地心至50 000km高空的地球空间,将整个地球及邻近空间分成约10 30个1~32级尺度的体元,每个体元都有一个唯一的整型编码。
2)立体网格与球面网格的一致性。当GeoSOT地球空间参考网格高度为大地高时(或地球平均半径),此时,高度维退化,真三维地球空间参考网格框架就变为二维地球球面上的参考网格框架。因此,GeoSOT立体空间参考网格与球面空间参考网格形成无缝连接,立体空间参考网格也能无缝关联球面数据。
3)包容性。GeoSOT的网格与国内外经纬度标准网格具有良好的包容关系,GeoSOT网格包容了国内外主要的测绘、气象、海洋、国家地理网格。
GeoSOT网格通过地球表面经纬度范围空间经过3次扩展后再对其进行严格的递归四叉剖分,由此将整个地球分割为大到全球、小到厘米级的整度、整分、整秒和秒以下的层次网格体系。其中,第1次空间扩展是将整个地球表面扩展为512°×512°,面片中心与赤道和本初子午线的交点重合,然后递归四叉剖分,直到1°网格单元;第2次空间扩展是将1°网格单元从60′扩展为64′,然后递归四叉剖分,直到1′网格单元;第3次空间扩展是将1′网格单元从60″扩展为64″,然后递归四叉剖分,直到1″网格单元。1″以下剖分单元直接采用四叉分割,直32级到(1/2048)″。这样,整个地球表面经纬度空间在经线方向和纬线方向通过严格的2分方法,将整个地球表面分割为覆盖全球的多级网格体系。所以,GeoSOT地球空间参考网格的体元是多尺度的,并且每一尺度的体元均无缝、无叠充满着整个地球立体空间。 空间网格是在经线方向和纬线方向上按等经纬度递归四叉树剖分的方法,对地球球面进行规格划分,然后对划分的面片单元进行有序规则的编码,构建一种适用于空间信息高效组织的剖分网,从而实现了整度、整分、整秒的四叉树剖分,形成一个大至地球、小至厘米级面元(32级)的多尺度四叉树网格;因此,理论上任何空天地对象都可以用相应的体元或面片聚合而成。包括:传统的测绘、气象、海洋、遥感等地球表面信息,以及海洋(水下)信息、气象云体、重力场、电磁场等各类立体空天信息。)另外,基于GeoSOT地球空间参考网格框架,可以为空、天、地、地(水)下动目标的组织与管理提供一种新的标识方法。由于GeoSOT空间网格充满着整个地球空间,任何一个动目标只要赋予其某一时刻处于的空间网格编码(加时间属性),就能实现地球空间范围内,动目标的描述、表达与展示。对每一个动目标,都采用(C,T,A)三元组进行描述,其中C为若干个体元(面片)的集合(C0C1,…,Cn),T记录时间属性,A为对象的基本属性信息的集合(A0A1,…,An)。
空天地数据的统一关联:基于GeoSOT网格的多尺度特性,既可以对大到整个地球,小到厘米级尺度的空间对象赋予唯一的网格编码,依靠这些编码,空间信息自动形成了在地球空间上的逻辑关联。
本公开的一可选实施例中,一个小区对应一个相同的同步信号;或者,一个小区内的一个空间网格和/或空间网格群对应一个相同的同步信号;所述同步信号包括:主同步信号(Primary Synchronization Signal,PSS)、辅同步信号(Secondary Synchronization Signal,SSS)和同步信号块(Synchronization Signal Block,SSB)中的至少一项。
可选的,所述小区的大小和形状为可变的,或者,所述小区内的空间网格和/或空间网格群的大小和形状为可变的。该小区的大小和形状可以变化,根据需求的不同,进行适应的变化,变化过程中,一个小区内的一个空间网格和/或空间网格群也可能会发生对应的变化。

本公开的可选实施例中,在一段时间T内,多个发射点在不同时间点和/ 或不同的频域资源发送不同的同步信号,多个发射点在时间T内形成不同的小区;所述同步信号包括:主同步信号PSS、辅同步信号SSS和同步信号块SSB中的至少一项。一个发射点可以发送不同的同步信号;比如,不同的时间点和/或不同的频域资源上;于是,这个发射点可以在不同时间点形成不同的小区,或者在不同的频域资源上形成不同的小区;可选的,这个发射点可以在不同时间点和其他发射点形成不同的小区,或者在不同的频域资源和其他发射点上形成不同的小区;比如,一个区域内有发射点A,B,C,D,E;
在T的一段时间内,在t1时刻,A,B,C都发送PCI为101的同步信号;D,E,F都发送PCI为102的同步信号;在t2时刻,A,B,D都发送PCI为103的同步信号;C依然发送PCI101的同步信号;E,F依然发送PCI102的同步信号;或者,在t2时刻,A,B,D都发送PCI为103的同步信号;C和E依然发送PCI104的同步信号;F依然发送PCI107的同步信号;在t3时刻,A,C,F发送PCI105的同步信号,B,C,E发送PCI106的同步信号;然后按一个特定周期循环发送。当这个区域的用户分布,用户密度和/或业务模型发生改变时,再更新发射点的同步信号发送行为。
如图2至图5所示,比如,一个区域内有发射点1,2,3,4;在t1时刻,网络预测出上升飞行的飞行器较多,则发射点1,2都发送PCI为101的同步信号,形成小区1;同时,在坐标右侧,网络于此处上升飞行的,或者下降的飞行器较多,则发射点3,4都发送PCI为102的同步信号,形成小区2;在t2时刻,网络预测出在高度h1,高度h2水平飞行的飞行器较多,则发射点1,3都发送PCI为103的同步信号;发射点2,4发送PCI104的同步信号;分别形成小区2和小区4。
如图4和图5所示,终端在基站1和基站2形成的小区1中起飞,根据终端的飞行路径,可形成如中间大椭圆所示的小区,终端可以接入该小区中。

可选的,该小区的广播消息或者专用消息中针对不同的高度和/或角度分别发送用于无线链路失败监测的配置参数,如N310,该参数表示接收连续“失步(out-of-sync)”指示的最大数目,达到最大数目后触发T310定时器的启动;T310,UE的RRC层检测到physical layer problems时,启动定时器T310.该定时器运行期间,如果无线链路恢复,则停止该定时器,否则一直运行。该定时超时,认为无线链路失败;N311该参数用于设置停止T310定时器所需要收到的最大连续“in-sync”指示的个数。
可选的,该小区的广播消息或者专用消息中针对不同的高度和/或角度分别发送用于干扰控制的配置信息,具体值可以相同,也可以不同:比如,上行负载信息包括高抗干扰指标(High Interference Indicator,HII)和超负荷指示器(Overload Indicator,OI)两个参数中加入高度和/或角度的信息。下行ICIC中需要传输相对窄带发射功率指示(Relative Narrowband Tx Power,RNTP)参数中加入高度和/或角度的信息。该参数用来指示本小区物理资源块 (PRB)上的下行发送功率等级,通知邻小区哪些PRB以高功率发送,邻小区在调度边缘UE时尽量避开这些PRB。
可选的,该小区的广播消息或者专用消息中针对不同的高度和/或角度分别发送用于数据调度的配置信息,具体值可以相同,也可以不同:比如,非连续接收(DRX)参数中DRX周期,UE唤醒时间On Duration,DRX静止定时器DRX-InactivityTimer,唤醒定时器OnDurationTimer,DRX超始偏移drxStartOffset,混合自动重传HARQ RTT Timer的定时器信息;MAC调度参数,如逻辑信息的优先级等,RLC的配置参数,如RLC的重排序窗长,RLC的定时器等,分组数据汇聚协议PDCP的配置参数,业务数据适应协议SDAP的配置参数。
可选的,该小区的广播消息或者专用消息中针对不同的高度和/或角度分别发送用于功率控制的配置信息,具体值可以相同,也可以不同:比如,PUSCH的功率控制公式找那个加入高度h和/或角度ag的维度:
增强为:

d,l)=f(资源的时间,资源的频域,资源的高度);
或者:
Ppusch’(i,j,q

功率控制的对象包括物理上行控制信道(PUCCH),物理上行共享信道PUSCH,信道探测参考信号SRS,随机接入前导码RA preamble,随机接入RA Msg3等。
UE发射的功率谱密度(即每RB上的功率)=开环工控点+动态的功率偏移。
其中开环工控点=标称功率P0+开环的路损补偿α×(PL)。
其中,标称功率P0又分为小区标称功率和UE特定的标称功率两部分。网络为小区内的所有UE半静态地设定针对不同的高度和/或角度的标称功率P0_PUSCH和P0_PUCCH,该值通过***消息广播;
除此之外,每个UE还可以有终端专用(UE specific)的标称功率偏移,该值通过专用RRC信令(比如,p0-UE-PUSCH,p0-UE-PUCCH)下发针对 不同的高度和/或角度的值配置给UE,值可以相同,可以不同。P0_UE_PUSCH和P0_UE_PUCCH的单位是dB,是不同UE对于***标称功率P0_PUSCH和P0_PUCCH的一个偏移量。
发送给UE针对不同的高度和/或角度的半静态调度的上行传输,P0_PUSCH的配置,值可以相同,可以不同(比如,SPS-ConfigUL:p0-NominalPUSCH-Persistent)。
开环的路损补偿PL基于UE对于下行的路损估计。UE通过测量下行参考信号RSRP,并与已知的AP对应的RS信号功率进行相减,从而进行路损估计。已知的AP对应的RS信号的原始发射功率在***消息中广播。
对于PUCCH来说,由于不同的PUCCH用户是码分复用的,α取值为1,可以更好地控制不同PUCCH用户之间的干扰。
动态的功率偏移包含两个部分,基于调制与编码策略MCS的功率调整△TF和闭环的功率控制。发送给UE针对不同的高度和/或角度的MCS的功率调整△TF和闭环的功率控制配置,值可以相同,可以不同。
