相关申请的交叉引用
本申请主张在2018年9月10日在中国提交的中国专利申请号No.201811052563.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种信息传输方法、网络设备及终端。
背景技术
在第五代(5 th Generation，5G)移动通信系统中，为达到下行链路传输速率20Gbps，上行链路传输速率10Gbps的目标，高频通信和大规模天线技术被引入。高频通信可提供更宽的系统带宽，天线尺寸也可以更小，更加有利于大规模天线在网络设备和终端(User Equipment，UE)中部署。网络设备侧可支持多波束(Multi-beam)/多收发节点(Transmit Receive Point，Multi-TRP)的发送和接收，终端侧也可支持Multi-beam的发送和接收。
其中，每个小区可以通过多个窄波束进行信号发送，多个波束的发送可以是时分的，每个波束可以覆盖小区的某一个方向。某个时刻通过一个窄波束发送相比通过一个宽波束(如覆盖整个小区的beam)发送的增益大约是9dB(8倍)。但单小区多波束的发送方案中，终端需要在小区间频繁的进行小区重选。
而单频网(Single-Frequency Network，SFN)传输方案为：多个小区或多个发送点发送同样的信号，不同小区间没有同频干扰，且多个信号可提升信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)、传输质量和覆盖效果。多个小区可以通过SFN传输的方式进行信号的发送，其中每个小区以宽波束发送，某一时刻终端可以接收到多个小区发送的宽波束，从而获得分集增益。终端接收到的最强的小区一般是3个，假设三个小区的信号强度相当，则接收到三个小区的信号能量是接收到单个小区信号能量的3倍， 约4dB增益。SFN传输方案中，终端不需要在小区间频繁的进行小区重选，但该方案的传输增益比窄波束传输方案的传输增益低，存在覆盖问题。
发明内容
本公开实施例提供了一种信息传输方法、网络设备及终端，以解决信息传输过程中传输增益低或频繁小区重选的问题。
第一方面，本公开实施例提供了一种信息传输方法，应用于网络设备，包括：
通过单频网小区组的第一波束，向终端发送下行信息；其中，单频网小区组包括至少两个小区，至少两个小区包括支持至少两个波束传输的第一小区，第一波束为第一小区支持的波束中的一个。
第二方面，本公开实施例还提供了一种信息传输方法，应用于终端，包括：
通过单频网小区组的第一波束，接收下行信息；其中，单频网小区组包括至少两个小区，至少两个小区包括支持至少两个波束传输的第一小区，第一波束为第一小区支持的波束中的一个。
第三方面，本公开实施例提供了一种网络设备，包括：
第一发送模块，用于通过单频网小区组的第一波束，向终端发送下行信息；其中，单频网小区组包括至少两个小区，至少两个小区包括支持至少两个波束传输的第一小区，第一波束为第一小区支持的波束中的一个。
第四方面，本公开实施例提供了一种网络设备，网络设备包括处理器、存储器以及存储于存储器上并在处理器上运行的程序，处理器执行该程序时实现上述的信息传输方法的步骤。
第五方面，本公开实施例提供了一种终端，包括：
第一接收模块，用于通过单频网小区组的第一波束，接收下行信息；其中，单频网小区组包括至少两个小区，至少两个小区包括支持至少两个波束传输的第一小区，第一波束为第一小区支持的波束中的一个。
第六方面，本公开实施例还提供了一种终端，终端包括处理器、存储器以及存储于存储器上并在处理器上运行的程序，该程序被处理器执行时实现 上述的信息传输方法的步骤。
第七方面，本公开实施例提供了一种计算机可读存储介质，计算机可读存储介质上存储有程序，该程序被处理器执行时实现上述的信息传输方法的步骤。
这样，本公开实施例通过单频网小区组内的多个小区传输信息，可获得单频网增益，提高网络覆盖率，同时可减少小区重选的次数；此外，进一步通过多个小区支持的多个波束中的第一波束传输信息，可获得窄波束增益，进一步提高网络覆盖率。

具体实施方式
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。
本公开的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类 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，以便这里描述的本公开的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。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。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
请参见图1，图1示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括网络设备01和终端02。其中，网络设备01可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，其中，基站可被称为节点B、演进节点B、接入点、基收发机站 (Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本公开实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。终端02也可以称作终端设备或者用户终端(User Equipment，UE)，终端02可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本公开实施例中并不限定终端02的具体类型。
基站可在基站控制器的控制下与终端02通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端02进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从终端02到网络设备01)的上行链路，或用于承载下行链路 (Downlink，DL)传输(例如，从网络设备01到终端02)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。
如图1所示的场景中，网络设备01和终端02之间通过天线波束实现信号传输，天线波束为空域传输滤波器形成的。网络设备01和终端02均可包含多个波束，以图1为例，假设网络设备01包含N个发送接收点(Transmit Receive Point，TRP)，每个TRP包括一个空域传输滤波器，以形成N个波束，终端02包含M个空域传输滤波器，以形成M个波束，其中N、M均为大于1的整数。N和M可以相同也可以不相同，本公开不作限制。
本公开实施例提供了一种信息传输方法，应用于网络设备，如图2所示，该方法包括：
步骤21：通过单频网小区组的第一波束，向终端发送下行信息；其中，单频网小区组包括至少两个小区，至少两个小区包括支持至少两个波束传输的第一小区，第一波束为第一小区支持的波束中的一个。
本公开实施例中，单频网小区组(SFN cell group)内包括多个小区，SFN cell group所包含的小区可以由网络设备配置，如网络设备可配置SFN cell group内小区的数量和小区标识，这些小区中包括支持多个波束的第一小区，其中，单频网小区组内所有支持多波束传输的小区均称为第一小区，第一小区的个数可以是一个，也可以是多个。第一波束可以是单频网小区组内小区所支持的波束中的一个。值得指出的是，单频网小区组内所包含的小区可以是支持相同波束数量的小区，如单频网小区组内所有小区均支持2个波束，那么单频网小区组内的所有小区均为第一小区，第一波束为第一小区所支持波束中的一个。单频网小区组内所包含的小区还可以是支持不同波束数量的小区，如单频网小区组内部分小区支持2个波束，那么第一波束为第一小区所支持的2个波束中的一个，其余部分小区支持1个波束，第一波束还可以为其余部分小区支持的那个波束。
其中，单频网小区组内小区的波束是按照时分方式传输的。例如单频网小区组包括小区1和小区2，小区1和小区2均支持波束1和波束2。那么T1时刻，小区1和小区2均通过波束1传输；T2时刻，小区1和小区2均通过波束2传输。也就是说T1时刻，单频网小区组的所有小区通过波束1 发送，T2时刻，单频网小区组所有小区通过波束2发送，若每小区支持更多波束，以此类推，例如4个beam，T1时刻，单频网小区组的所有小区通过波束1发送，T2时刻，单频网小区组所有小区通过波束2发送，T3时刻，单频网小区组的所有小区通过波束3发送，T4时刻，单频网小区组所有小区通过波束4发送。或者，单频网小区组包括小区1和小区2，小区1支持一个波束(波束1)，小区2支持波束1和波束2，那么T1时刻，小区1和小区2均通过各自的波束1传输；T2时刻，小区1仍通过其对应的波束1传输，小区2通过其对应的波束2传输。又或者，单频网小区组包括小区1和小区2，小区1支持波束1和波束2，小区2支持波束1、波束2、波束3和波束4，那么T1时刻，小区1和小区2均通过各自的波束1传输；T2时刻，小区1仍通过其对应的波束1传输，小区2通过其对应的波束2传输；T3时刻，小区1通过其对应的波束2传输，小区2通过其对应的波束3传输；T4时刻，小区1通过其对应的波束2传输，小区2通过其对应的波束4传输。其中，本实施例所说的波束1、波束2、波束3和波束4等仅为波束编号，不同小区对应有相同编号的波束的波束方向可以不同，例如当小区1仅支持波束1时，波束1为全向波束；当小区1支持波束1和波束2，波束1和波束2均为窄带波束。
本公开实施例中，步骤21包括：在不同传输时间段内，通过单频网小区组的第一波束，向终端发送下行信息。这里所述的不同传输时间段指的是对应于第一波束的不同传输时间段，例如在T1时刻传输波束1，在T2时刻传输波束2，在T3时刻传输波束1，在T4时刻传输波束2，对应于波束1的不同传输时间段指的是T1和T3，对应于波束2的不同传输时间段指的是T2和T4。
进一步地，下行信息是以传输时间段为单位重复发送的，也就是说网络设备可支持信号在时间上的重复发送，例如每个下行信息在同一波束的多个时刻重复发送，对应的终端可以在多个时刻进行该波束信号的合并接收。例如在T1时刻和T3时刻通过波束1重复发送下行信息。或者，下行信息是通过不同传输时间段内的第一波束联合发送的。具体地，将下行信息进行信道编码和速率匹配，得到待发送的比特序列，将比特序列划分多个比特子序列， 并通过不同传输时间段的第一波束发送。例如，将下行信息的比特序列分为2个比特子序列，在T1时刻和T3时刻通过波束1联合发送这两个比特子序列。
本公开实施例中，下行信息采用正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)方式发送，其OFDM方式采用扩展循环前缀(Cyclic Prefix，CP)或正常CP。下行信息采用扩展CP的OFDM方式传输，以对抗更大的多径时延扩展。
本公开实施例的下行信息是通过单频网小区组对应的专用带宽部分(Bandwidth Part，BWP)，如下行初始BWP(Down Initial BWP)，发送的。进一步地，网络设备可以将终端配置在单频网小区组对应的专用BWP上，或者，将终端配置在一个小区对应的BWP上。其中，两者之间可以互相切换，例如，网络设备可以将终端由单频网小区组的专用BWP切换至小区的BWP上，反之亦可，故在此不再赘述。
其中，本公开实施例的下行信息包括：同步信号块(Synchronization Signal and PBCH Block，SSB)、寻呼(Paging)信号、唤醒信号(Wake Up Signal，WUS)、睡眠信号(Go To Sleep Signal，GTS Signal)、物理广播信道(Physical Broadcast Channel，PBCH)、专用解调参考信号(De-Modulation Reference Signal，DMRS)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)和系统消息块(System Information Block，SIB)所承载的信息中至少一项。这些下行信息均可采用扩展CP或正常CP的OFDM方式，在单频网小区组的第一波束对应的不同传输时间段内重复或联合发送。
其中，下行信息的传输格式相关信息是通过小区专用(cell specific)信息配置的，如通过cell specific的PBCH、SIB1或无线资源控制(Radio Resource Control，RRC)信令等。或者，传输格式相关信息是通过单频网小区组专用(SFN based)信息配置的，如通过SFN based的PBCH、SIB1或者RRC信令等。或者，传输格式相关信息是预定义的，如协议约定。其中，这里所说的传输格式相关信息包括：传输周期、参数集(Numerology)、波束的数目、时频域资源中的至少一项。其中，参数集包括：子载波间隔、OFDM符号长度和CP长度等的至少一项。
其中，网络设备还可以：配置终端通过SFN小区组专用的SSB、CSI-RS和DMRS的至少一项进行无线资源管理(Radio Resource Management，RRM)测量和/或无线链路监测(Radio Link Monitoring，RLM)测量。
进一步地，单频网小区组内的小区包括：跟踪区(Tracking Area，TA)内的小区、TA列表(TA list)中的小区或基于无线接入网通知(RAN-based Notification Area，RNA)区域的小区。其中，跟踪区是系统为终端的位置管理设立的概念。当终端处于空闲状态时，网络设备能够知道终端所在的跟踪区，同时当处于空闲状态的终端需要被寻呼时，必须在终端所注册的跟踪区的所有小区进行寻呼。其中，TA是小区级的配置，多个小区可以配置相同的TA，且一个小区只能属于一个TA。跟踪区标识(Tracking Area Identity，TAI)是由公共陆地移动网络(Public Land Mobile Network，PLMN)和跟踪区码(Tracking Area Code，TAC)组成：TAI＝PLMN+TAC。如图3所示，多个TA组成一个TA列表，同时分配给一个终端，终端在该TA列表内移动时不需要执行TA更新，以减少与网络的频繁交互；当终端进入不在其所注册的TA列表中的新TA区域时，需要执行TA更新，网络设备给终端重新分配一组TA，新分配的TA也可包含原有TA列表中的一些TA。如果终端在TA list里的多个TA间移动，是不做TA更新。RNA覆盖的小区集合可以是组成一个TA或TA列表的小区集合的子集。
其中，步骤21之前，还包括：为终端配置单频网小区组的组相关信息，其中，组相关信息包括：单频网小区组标识、单频网小区组频点和同步信号块图样(pattern)中的至少一项。
其中，终端接入一个SFN cell group时，RRM测量周期可以放松，也就是说，单频网小区组的无线资源管理RRM测量周期大于或等于小区的RRM测量周期；其中，该小区是单频网小区组包含的小区。
其中，单频网小区组支持专用波束管理(beam management)和/或专用波束失败恢复(Beam Failure Recovery，BFR)。也就是说，系统支持SFN cell group specific的波束管理和/或波束失败恢复。
其中，单频网小区组对应的SSB的同步光栅(sync raster)与一个小区对应的SSB的同步光栅不同。也就是说，SFN SSB的位置可以跟cell SSB的sync  raster不一样，值得指出的是，初始接入时终端不搜索SFN SSB。
其中，单频网小区组的SSB、CSI-RS和DMRS中的至少一项对应有单频网小区组专用的生成序列和/或加扰序列。例如，单频网小区组的用于解调PBCH的DMRS(SFN based DMRS)对应有专用的加扰相位(scrambling phase)和生成序列。
其中，单频网小区组的信号质量是终端根据单频网小区组的波束检测确定的，例如，可以通过对单频网小区组内的多个波束的联合检测来评估SFN cell group的信号质量。
此外，网络设备还可以配置SFN cell group specific BWP的开和关。配置SFN cell group specific BWP上的SSB、PBCH、SIB、Paging、WUS和GTS中至少一项的开和关。还可以配置终端驻留在SFN的SSB上，或者驻留在小区的SSB上，二者之间支持互相切换。
本公开实施例可获得单频网增益，提高网络覆盖率，同时可减少小区重选的次数；此外，还可获得窄波束增益，进一步提高网络覆盖率。

其中，单频网小区组对应的SSB的同步光栅与一个小区对应的SSB的同步光栅不同。也就是说，SFN SSB的位置可以跟cell SSB的同步光栅不一样，值得指出的是，初始接入时终端不搜索SFN SSB。
其中，单频网小区组的SSB、CSI-RS和DMRS中的至少一项对应有单频网小区组专用的生成序列和/或加扰序列。例如，单频网小区组的用于解调PBCH的DMRS对应有专用的加扰相位和生成序列。
其中，单频网小区组的信号质量是根据单频网小区组的波束检测确定的，例如，可以通过对单频网小区组内的多个波束的联合检测来评估SFN cell group的信号质量。
此外，网络设备还可以配置SFN cell group specific BWP的开和关。配置SFN cell group specific BWP上的SSB、PBCH、SIB、Paging、WUS和GTS signal中至少一项的开和关。还可以配置终端驻留在SFN的SSB上，或者驻留在小区的SSB上，二者之间支持互相切换。
