Abstract

本申请公开了一种带内中继方法，由于中继设备可以从第二子帧集合中选择一个第二子帧分配给终端设备，相比于现有标准中，最少只能以3个子帧为单位进行配置，本实施例至少可以以1个子帧为单位进行配置，进而，可以实现对中继设备下的终端设备的周期CQI资源和SRI资源进行精准的控制。

Description

一种带内中继方法、中继设备和网络设备
本申请要求于2019年04月16日提交中国国家知识产权局、申请号为201910304609.0、发明名称为“一种带内中继方法、中继设备和网络设备”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
本申请涉及移动通信领域，尤其涉及一种带内中继方法、中继设备和网络设备。
背景技术
第三代合作伙伴计划(3rd generation partnership project，3GPP)标准定义的Relay组网包含宿主基站(donor eNodeB，简称DeNB)和中继设备relay两个逻辑节点。DeNB是在普通基站(eNodeB，eNB)的基础上增加了对relay特性相关功能的支持，DeNB在接入普通用户设备(user equipment，UE)的同时，也支持接入relay，并承载relay的回传流量。relay逻辑上划分为中继用户设备(relay user equipment，RUE)和中继基站(relay eNodeB，ReNB)两部分：ReNB可供覆盖范围内的普通UE接入，与普通UE建立接入链路；RUE接入DeNB，并建立空口承载为RUE提供回传链路。若relay的回传链路和接入链路使用相同的频段，则称为带内relay；若relay的回传链路和接入链路使用不同的频段，则称为带外relay。
其中，带内relay的回传链路和接入链路占用的总频谱小于带外relay，即频谱效率高于带relay。但带内relay需要解决回传链路和接入链路之间的干扰问题。3GPP标准定义了一种时分复用(time division multiplexing，TDM)的方式来避免带内relay回传链路和接入链路之间的相互干扰。具体是在下行方向上，同一时刻仅有下述两个动作中的一个发生：RUE接收DeNB的数据，ReNB向其下的普通UE发数据；在上行方向上，同一时刻仅有下述两个动作中的一个发生：RUE向DeNB发送数据，ReNB接收普通UE的数据。
现有技术中，DeNB通过中继子帧的配置来避免带内relay回传链路和接入链路之间的相互干扰，具体的，DeNB通过信元SubframeConfigurationFDD下发到RUE，信元SubframeConfigurationFDD的配置如下表1：
表1
Figure PCTCN2020077425-appb-000001
Figure PCTCN2020077425-appb-000002
其中，每种信元SubframeConfigurationFDD对应一个ΔBSC，且ΔBSC取值满足如下公式(10×n f+[n s/2])mod 8∈ΔBSC，以ΔBSC＝7为例，n f和n s取值为(0，14)，(1，10)，(2，6)，(3，2)对应的40ms子帧分别为7、15、23、31子帧，由于系统消息在0、4、5、9子帧下发，因此15子帧不能配置，即当ΔBSC＝7时，代表配置子帧为7、23、31。同理，当信元SubframeConfigurationFDD为其他情况时，每个信元SubframeConfigurationFDD对应3个子帧，且是在40ms内，最少只能以3个子帧为单位进行配置，因此，不能对ReNB下的用户的周期CQI资源和SRI资源进行精准的控制。

从以上技术方案可以看出，本申请具有以下优点：
本申请实施例提供了一种带内中继方法，包括：中继设备接收到网络设备发送的根据第一子帧集合分配的一个第一子帧，其中，所述一个第一子帧属于所述第一子帧集合，所述第一子帧集合包括至少一个第一子帧，所述至少一个第一子帧中的每个第一子帧之间不同，所述每个第一子帧用于指示第一链路在一个调度周期内占用的上行控制信道资源，所述第一链路为所述网络设备与接入所述网络设备的所述中继设备之间的链路；所述中继设备根据接收到的所述一个第一子帧配置上行控制信道资源；所述中继设备根据第二子帧集合为第一终端设备分配一个第二子帧，其中，所述一个第二子帧属于所述第二子帧集合，所述第二子帧集合包括至少一个第二子帧，所述至少一个第二子帧中的每个第二子帧之间不同，所述每个第二子帧用于指示第二链路在一个调度周期内占用的上行控制信道资源，所述第二链路为所述中继设备与接入所述中继设备的第一终端设备之间的链路，且所述第一子帧集合和所述第二子帧集合的交集为空集；所述中继设备向所述第一终端设备发送所述一个第二子帧。通过上述方式，由于网络设备是从第一子帧集合中选择一个子帧分配给中继设备，且中继设备是从第二子帧集合中选择一个第二子帧分配给终端设备，由于第一子帧集合和第二子帧集合交集为空集，即第一子帧集合和第二子帧集合不包含相同的子帧，则网络设备给中继设备分配的子帧和中继设备给终端设备分配的子帧不同，消除了RUE会对接入ReNB的终端设备存在阻塞上行控制信道干扰，以及消除了接入ReNB的终端设备会 对RUE存在阻塞上行控制信道干扰。另一方面，由于中继设备可以从第二子帧集合中选择一个第二子帧分配给终端设备，相比于现有标准中，最少只能以3个子帧为单位进行配置，本实施例至少可以以1个子帧为单位进行配置，进而，可以实现对ReNB下的用户的周期CQI资源和SRI资源进行精准的控制。

具体实施方式
本申请提供了一种带内中继方法、中继设备和网络设备，可以实现对ReNB下的用户的周期CQI资源和SRI资源进行精准的控制。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
应当理解，尽管在本申请实施例中可能采用术语第一、第二、第三等来描述各种报文/帧、请求和终端，但这些报文/帧、请求和终端不应限于这些术语。这些术语仅用来将报文/帧、请求和终端彼此区分开。例如，在不脱离本申请实施例范围的情况下，第一终端也可以被称为第二终端，类似地，第二终端也可以被称为第一终端。
取决于语境，如在此所使用的词语“如果”或“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地，取决于语境，短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
为了便于实施例的描述，下面先简单介绍一下本发明实施例的应用场景。参见图1， 该场景为relay组网，包括DeNB 10、relay 20、接入在relay 20下的第一UE 30和接入在DeNB 10下的第二UE40。其中，DeNB10在支持第二UE40接入的同时，也支持relay20接入，并承载relay 20的回传流量。relay 20逻辑上划分为RUE和ReNB两部分：ReNB可供覆盖范围内的第一UE 30接入，与第一UE 30建立接入链路；RUE接入DeNB 10，并建立LTE空口承载为ReNB提供回传链路。
其中，第一UE 30可以指本申请中的第一终端设备，第二UE 40可以指本申请中的第二终端设备，DeNB 10可以指本申请中的网络设备，relay 20可以指本申请中的中继设备。
在本发明实施例中，一个DeNB 10下可以接入一个或多个relay 20。
在本发明实施例中，网络设备可以为基站或其他接入网设备，基站可以用于与一个或多个终端进行通信，也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站，如接入点，之间的通信)。基站可以是时分同步码分多址(time division synchronous code division multiple access，TD－SCDMA)系统中的基站收发台(base transceiver station，BTS)，也可以是LTE系统中的演进型基站(evolutional node B，接入网设备)，以及5G系统、新空口(NR)系统中的基站gNB。另外，基站也可以为接入点(access point，AP)、传输节点(trans TRP)、中心单元(central unit，CU)或其他网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。
终端设备可以分布在整个无线通信系统中，可以是静止的，也可以是移动的。在本申请的一些实施例中，本申请实施例中的终端设备为具有无线收发功能的设备，包括但不限于用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备101还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SOP190191)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，无人机设备，智能家居，以及5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
中继设备可以分布在小区边缘，可扩大网络设备的覆盖范围。中继设备可以包含两个物理层实体。其中，一个实体用于和其下属用户(即接入到中继设备的终端设备)通信。另一个实体具有用户功能(即终端功能)，用于网络设备通信。具体实现中，中继设备可以是中继基站，例如微基站等。中继设备也可以是中继终端，例如空闲终端。中继设备还可以是中继收发节点(TRP)，用户终端设备(customer premise equipment，CPE)，中继收发器、中继代理等网络实体。
在一种场景中，参照图2，图2为同频relay共站的部署系统图。对于relay而言，如果relay上和网络设备通讯的接口和与终端设备通讯的接口复用相同的载波频率资源，则为带内relay，即，同频relay共站部署，此时，无线回传的中继回传节点(relay remote node，RRN)部署在ReNB的铁塔/杆上，对于RRN来说，DeNB的小区是RUE的服务小区，而ReNB是RRN 的一个邻区站，同时RRN和ReNB频点一样。

以一个调度周期为10ms为例，此时，第四子帧集合为{0,1,2,3,4,5,6,7,8,9}，示例性的，第一子帧集合为{0}，第二子帧集合为{1，3,5,7,9}，第三子帧集合为{2，4，6，8}，可见，所述第一子帧集合{0}、所述第二子帧集合{1，3,5,7,9}和所述第三子帧集合{2，4，6，8}中任意两个子帧集合的交集为空集，且所述第一子帧集合{0}、所述第二子帧集合{1，3,5,7,9}和所述第三子帧集合{2，4，6，8}的并集为第四子帧集合{0,1,2,3,4,5,6,7,8,9}。
示例性的，第一子帧集合为{0，2,4}，第二子帧集合为{1，3,5,7,9}，第三子帧集合为{6，8}，可见，所述第一子帧集合{0，2,4}、所述第二子帧集合{1，3,5,7,9}和所述第三子帧集合{6，8}中任意两个子帧集合的交集为空集，且所述第一子帧集合{0，2,4}、所述第二子帧集合{1，3,5,7,9}和所述第三子帧集合{6，8}的并集为第四子帧集合{0,1,2,3,4,5,6,7,8,9}。
需要说明的是，以上仅为第一子帧集合、第二子帧集合和第三子帧集合的两种示例，实际应用中，可按照需求选择，只要满足所述第四子帧集合包括一个调度周期占用的全部子帧，所述第一子帧集合、所述第二子帧集合和所述第三子帧集合中任意两个子帧集合的交集为空集，且所述第一子帧集合、所述第二子帧集合和所述第三子帧集合的并集为所述第四子帧集合即可，本申请实施例并不限定。

示例性的，第一子帧集合为{0，2,4}，第二子帧集合为{1，3,5,7,9}，第三子帧集合为{6，8}，可见，所述第一子帧集合{0，2,4}、所述第二子帧集合{1，3,5,7,9}和所述第三子帧集合{6，8}中任意两个子帧集合的交集为空集，且所述第一子帧集合{0，2,4}、所述第二子帧集合{1，3,5,7,9}和所述第三子帧集合{6，8}的并集为第四子帧集合{0,1,2,3,4,5,6,7,8,9}。
需要说明的是，以上仅为第一子帧集合、第二子帧集合和第三子帧集合的两种示例，实际应用中，可按照需求选择，只要满足所述第四子帧集合包括一个调度周期占用的全部子帧，所述第一子帧集合、所述第二子帧集合和所述第三子帧集合中任意两个子帧集合的交集为空集，且所述第一子帧集合、所述第二子帧集合和所述第三子帧集合的并集为所述第四子帧集合即可，本申请实施例并不限定。
本申请实施例中，网络设备根据第一子帧集合为中继设备分配一个第一子帧，其中，所述一个第一子帧属于所述第一子帧集合，第一子帧集合包括至少一个第一子帧，所述至少一个第一子帧中的每个第一子帧之间不同，所述每个第一子帧用于指示第一链路在一个 调度周期内占用的上行控制信道资源，所述第一链路为所述网络设备与接入所述网络设备的所述中继设备之间的链路；所述网络设备根据第三子帧集合为第二终端设备分配一个第三子帧，其中，所述一个第三子帧属于所述第三子帧集合，所述第三子帧集合包括至少一个第三子帧，所述至少一个第三子帧中的每个第三子帧之间不同，所述每个第三子帧用于指示第三链路在一个调度周期内占用的上行控制信道资源，所述第三链路为所述网络设备与接入所述网络设备的所述第二终端设备之间的链路，且所述第一子帧集合和所述第三子帧集合的交集为空集；所述网络设备向所述中继设备发送所述一个第一子帧；所述网络设备向所述第二终端设备发送所述一个第三子帧。由于网络设备是从第一子帧集合中选择一个子帧分配给中继设备，且网络设备是从第三子帧集合中选择一个第三子帧分配给终端设备，由于第一子帧集合和第三子帧集合交集为空集，即第一子帧集合和第三子帧集合不包含相同的子帧，则网络设备给中继设备分配的子帧和网络设备给终端设备分配的子帧不同，使得中继设备和第二终端设备不存在上行控制信道(SR/CQI)资源的竞争。
图5提供了一种中继设备的结构示意图，参见图5，该中继设备包括：
接收模块501，用于接收到网络设备发送的根据第一子帧集合分配的一个第一子帧，其中，所述一个第一子帧属于所述第一子帧集合，所述第一子帧集合包括至少一个第一子帧，所述至少一个第一子帧中的每个第一子帧之间不同，所述每个第一子帧用于指示第一链路在一个调度周期内占用的上行控制信道资源，所述第一链路为所述网络设备与接入所述网络设备的所述中继设备之间的链路；
处理模块502，用于根据接收到的所述一个第一子帧配置上行控制信道资源；
所述处理模块502，还用于根据第二子帧集合为第一终端设备分配一个第二子帧，其中，所述一个第二子帧属于所述第二子帧集合，所述第二子帧集合包括至少一个第二子帧，所述至少一个第二子帧中的每个第二子帧之间不同，所述每个第二子帧用于指示第二链路在一个调度周期内占用的上行控制信道资源，所述第二链路为所述中继设备与接入所述中继设备的第一终端设备之间的链路，且所述第一子帧集合和所述第二子帧集合的交集为空集；
发送模块503，用于向所述第一终端设备发送所述一个第二子帧。
可选的，所述第一子帧集合、所述第二子帧集合和第三子帧集合属于第四子帧集合，其中，所述第三子帧集合包括至少一个第三子帧，所述至少一个第三子帧中的每个第三子帧之间不同，所述每个第三子帧用于指示第三链路在一个调度周期内占用的上行控制信道资源，所述第三链路为网络设备与接入所述网络设备的第二终端设备之间的链路，所述第四子帧集合包括一个调度周期占用的全部子帧，所述第一子帧集合、所述第二子帧集合和所述第三子帧集合中任意两个子帧集合的交集为空集，且所述第一子帧集合、所述第二子帧集合和所述第三子帧集合的并集为所述第四子帧集合。
可选的，所述中继设备包括：中继基站和中继用户设备，所述中继基站和中继用户设备通过通信接口相连接，所述中继基站。
可选的，所述中继用户设备包括接收模块501，所述接收模块501用于接收到网络设备发送的根据第一子帧集合分配的一个第一子帧。
可选的，所述中继基站包括第一处理模块，所述第一处理模块用于根据接收到的所述一个第一子帧配置上行控制信道资源。
所述中继基站包括第二处理模块，所述第二处理模块用于根据第二子帧集合为第一终端设备分配一个第二子帧；
所述中继基站包括发送模块503，所述发送模块503用于向所述第一终端设备发送所述一个第二子帧。
本申请实施例中，接收模块501接收到网络设备发送的根据第一子帧集合分配的一个第一子帧，其中，所述一个第一子帧属于所述第一子帧集合，所述第一子帧集合包括至少一个第一子帧，所述至少一个第一子帧中的每个第一子帧之间不同，所述每个第一子帧用于指示第一链路在一个调度周期内占用的上行控制信道资源，所述第一链路为所述网络设备与接入所述网络设备的所述中继设备之间的链路；处理模块502根据接收到的所述一个第一子帧配置上行控制信道资源；所述处理模块502根据第二子帧集合为第一终端设备分配一个第二子帧，其中，所述一个第二子帧属于所述第二子帧集合，所述第二子帧集合包括至少一个第二子帧，所述至少一个第二子帧中的每个第二子帧之间不同，所述每个第二子帧用于指示第二链路在一个调度周期内占用的上行控制信道资源，所述第二链路为所述中继设备与接入所述中继设备的第一终端设备之间的链路，且所述第一子帧集合和所述第二子帧集合的交集为空集；发送模块503向所述第一终端设备发送所述一个第二子帧。通过上述方式，由于网络设备是从第一子帧集合中选择一个子帧分配给中继设备，且中继设备是从第二子帧集合中选择一个第二子帧分配给终端设备，由于第一子帧集合和第二子帧集合交集为空集，即第一子帧集合和第二子帧集合不包含相同的子帧，则网络设备给中继设备分配的子帧和中继设备给终端设备分配的子帧不同，消除了RUE会对接入ReNB的终端设备存在阻塞上行控制信道干扰，以及消除了接入ReNB的终端设备会对RUE存在阻塞上行控制信道干扰。另一方面，由于中继设备可以从第二子帧集合中选择一个第二子帧分配给终端设备，相比于现有标准中，最少只能以3个子帧为单位进行配置，本实施例至少可以以1个子帧为单位进行配置，进而，可以实现对ReNB下的用户的周期CQI资源和SRI资源进行精准的控制。
如图6所示，在本发明实施例的一种实现方式中，RUE 61和ReNB 62为互相独立的两个部分。例如，RUE 61和ReNB 62可以是两个独立的设备，此时在两个设备中分别配置有具体的功能芯片，RUE61中的功能芯片用作接收模块501和第一处理模块601，ReNB 62中的功能芯片用作第二处理模块602和发送模块503。又例如，RUE 61和ReNB 62也可以是同一个设备箱内的两个芯片，此时在两个芯片中分别配置有具体的功能模块，RUE 61中的功能模块用作接收模块501和第一处理模块601，ReNB 62中的功能模块用作第二处理模块602和发送模块503。再例如，RUE 61和ReNB 62也可以是一个芯片上的两个功能模块，此时在两个功能模块中分别配置有具体的硬件电路，RUE 61中的硬件电路用作接收模块501和第一处理模块601，ReNB 62中的硬件电路用作第二处理模块602和发送模块503。
如图7所示，在本发明实施例的另一种实现方式中，RUE 61和ReNB 62之间可以共用部分硬件，例如如图所示，RUE 61和ReNB 62共用处理器6A和存储器6B等部件；而RUE 61 和ReNB 62中也设有各自独立的硬件部分，如RUE 61中的第一收发器6C，ReNB 62中的第二收发器6D，第一收发器6C和第二收发器6D可以分别用作前述接收模块501和发送模块503。
当然还可以在上述设备、芯片或者功能模块中存储对应的软件，使得软件执行过程中产生对应的功能，以实现接收模块501、处理模块502和发送模块503。

本申请实施例中，所述网络设备根据第一子帧集合为中继设备分配一个第一子帧，其中，所述一个第一子帧属于所述第一子帧集合，第一子帧集合包括至少一个第一子帧，所述至少一个第一子帧中的每个第一子帧之间不同，所述每个第一子帧用于指示第一链路在一个调度周期内占用的上行控制信道资源，所述第一链路为所述网络设备与接入所述网络设备的所述中继设备之间的链路；所述网络设备根据第三子帧集合为第二终端设备分配一个第三子帧，其中，所述一个第三子帧属于所述第三子帧集合，所述第三子帧集合包括至少一个第三子帧，所述至少一个第三子帧中的每个第三子帧之间不同，所述每个第三子帧用于指示第三链路在一个调度周期内占用的上行控制信道资源，所述第三链路为所述网络设备与接入所述网络设备的所述第二终端设备之间的链路，且所述第一子帧集合和所述第三子帧集合的交集为空集；所述网络设备向所述中继设备发送所述一个第一子帧；所述网络设备向所述第二终端设备发送所述一个第三子帧；所述第二终端设备根据接收到的所述一个第三子帧配置上行控制信道资源；所述中继设备根据接收到的所述一个第一子帧配置上行控制信道资源；所述中继设备根据第二子帧集合为第一终端设备分配一个第二子帧，其中，所述一个第二子帧属于所述第二子帧集合，所述第二子帧集合包括至少一个第二子帧，所述至少一个第二子帧中的每个第二子帧之间不同，所述每个第二子帧用于指示第二链路在一个调度周期内占用的上行控制信道资源，所述第二链路为所述中继设备与接入所述中继设备的第一终端设备之间的链路，且所述第一子帧集合和所述第二子帧集合的交集为空集；所述中继设备向所述第一终端设备发送所述一个第二子帧；所述第一终端设备根据接收到的所述一个第二子帧配置上行控制信道资源。通过上述方式，由于网络设备是从 第一子帧集合中选择一个子帧分配给中继设备，且中继设备是从第二子帧集合中选择一个第二子帧分配给终端设备，由于第一子帧集合和第二子帧集合交集为空集，即第一子帧集合和第二子帧集合不包含相同的子帧，则网络设备给中继设备分配的子帧和中继设备给终端设备分配的子帧不同，消除了RUE会对接入ReNB的终端设备存在阻塞上行控制信道干扰，以及消除了接入ReNB的终端设备会对RUE存在阻塞上行控制信道干扰。另一方面，由于中继设备可以从第二子帧集合中选择一个第二子帧分配给终端设备，相比于现有标准中，最少只能以3个子帧为单位进行配置，本实施例至少可以以1个子帧为单位进行配置，进而，可以实现对ReNB下的用户的周期CQI资源和SRI资源进行精准的控制。另一方面，由于网络设备是从第一子帧集合中选择一个子帧分配给中继设备，且网络设备是从第三子帧集合中选择一个第三子帧分配给终端设备，由于第一子帧集合和第三子帧集合交集为空集，即第一子帧集合和第三子帧集合不包含相同的子帧，则网络设备给中继设备分配的子帧和网络设备给终端设备分配的子帧不同，使得中继设备和第二终端设备不存在上行控制信道(SR/CQI)资源的竞争。
