Description

一种控制信息发送方法、基站、用户设备及系统 技术领域
本发明涉及通信技术领域,尤其涉及一种控制信息发送方法、基站、用户设备及系统。
背景技术
随着第四代移动通信技术的商用以及移动业务的持续增长,世界范围内已经开始了对于第五代通信技术(5th-Generation,5G)的研究工作。5G是一种多技术融合的通信,通过技术的更迭和创新来满足广泛的数据、连接业务的需求。在RAN71次会议中,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)成立了关于5G新空口研究的研究项目。根据5G对于垂直场景的划分,3GPP主要从三个方面进行新空口技术的研究:增强移动宽带(enhanced mobile broadband,eMBB)、高可靠低时延通信(ultra-reliable low-latency communications,URLLC)和大连接物联网(massive machine type communications,mMTC)。其中,关于URLLC控制信道的设计,由于该场景对时延和可靠性的特殊需求,以及控制信道本身对于系统性能的影响,将会是后续讨论的一个重要方向。
目前,为了提高控制信道传输下行控制信息(Downlink Control Information,DCI)可靠性,在RAN 1#87次会议上,针对URLLC场景的控制信道设计有了一些初步的讨论,例如,压缩DCI的长度、为DCI分配更多的资源以降低码率等等,但上述方法只能达到一定的可靠性,当对可靠性要求更高时,则上述方法无法满足。
发明内容
本发明实施例提供一种控制信息发送方法、基站、用户设备及系统,以期可以提高控制信道的接收成功率,以及提升控制信道的接收信号质量,减少控制信道的误码率。
第一方面,本发明实施例提供了一种控制信息发送方法,该方法包括:
确定当前子帧调度的N个用户设备中的至少一个用户设备的控制信息,所 述N为正整数;
确定所述控制信息所占的第一时频位置及第二时频位置;
采用第一类型波束向所述至少一个用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向所述至少一个用户设备发送所述第二时频位置的所述控制信息。
第二方面,本发明实施例提供了一种控制信息发送方法,该方法包括:
用户设备接收基站在第一时频位置发送的控制信息以及在第二时频位置发送的控制信息;
所述用户设备将从所述第一时频位置接收到的控制信息以及从所述第二时频位置接收到的控制信息进行分集合并处理获得所述控制信息。
第三方面,本发明实施例提供了一种基站,该基站包括:
确定单元,用于确定当前子帧调度的N个用户设备中的至少一个用户设备的控制信息,所述N为正整数;
所述确定单元,还用于确定所述控制信息所占的第一时频位置及第二时频位置;
发送单元,用于采用第一类型波束向所述至少一个用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向所述至少一个用户设备发送所述第二时频位置的所述控制信息。
第四方面,本发明实施例提供了一种用户设备,该用户设备包括:
接收单元,用于接收接收基站在第一时频位置发送的控制信息以及在第二时频位置发送的控制信息;
处理单元,用于将从所述第一时频位置接收到的控制信息以及从所述第二时频位置接收到的控制信息进行分集合并处理获得所述控制信息。
可以看出,本发明实施例所提供的技术方案中,基站在确定当前子帧调度的N个用户的至少一个用户的控制信息后,再确定该控制信息所占用的第一时频位置以及第二时频位置,并同时使用第一时频位置以及第二时频位置将该控制信息下发至用户设备,以使用户设备将从第一时频位置接收到的控制信息以及从第二时频位置接收到的控制信息进行分集合并处理得到控制信息,提高控制信道接收成功率,提升控制信道的接收信号质量,减少控制信道的误码率。

需要特别说明的是,下面本发明各实施例中对某种具体网络架构进行的描述只是一种示例(例如LTE/LTE-A),而不应理解为限定。本发明所公开的方法和装置同样可以应用到后续演进的(例如:下一代5G)的网络架构中。示例性的,其中各网元的描述如下:
移动性管理实体(Mobility Management Entity,MME)/服务网关(Serving GateWay,S-GW):MME是第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)LTE中的关键控制节点,属于核心网网元或核心网设备,主要负责信令处理部分,即控制面功能,包括接入控制、移动性管理、附着与去附着、会话管理功能以及网关选择等功能。S-GW是3GPP LTE中核心网的重要网元,主要负责用户面数据传输,以及用户数据转发、路由切换等用户面功能,即在MME的控制下进行数据包的路由和转发。eNB:eNodeB(eNB)可以是与用户设备UE通信的站,并且也可以称为基站、节点B、接入点、接入网设备等。每个eNB可以针对特定的地理区域提供通信覆盖。在3GPP中,术语“小区”根据使用该术语的上下文可以指eNB的这种特定的地理覆盖区域和/或服务于该覆盖区域的eNB子系统的这种特定的地理覆盖区域。eNB主要负责空口侧的无线资源管理、服务质量(QoS,Quality of Service)管理、数据压缩和加密等功能。往核心网侧,eNB主要负责向MME转发控制面信令以及向S-GW转发用 户面业务数据。eNB可以针对宏小区、微微小区、毫微微小区和/或其它类型的小区提供通信覆盖。宏小区通常覆盖相对较大的地理区域(例如,半径为几千米的范围),并且可以允许由具有与网络提供商的服务签约的UE无限制的接入。微微小区通常覆盖相对较小的地理区域,并且可以允许由具有与网络提供商的服务签约的UE无限制的接入。毫微微小区通常也覆盖相对较小的地理区域(例如,家庭),并且除了无限制的接入以外还可以提供由具有与毫微微小区关联的UE的受限的接入(例如,封闭用户组(Closed Subscriber Group,CSG)中的UE、家庭中的用户的UE等)。宏小区的eNB可被称为宏eNB。微微小区的eNB可被称为微微eNB。以及,毫微微小区的eNB可被称为毫微微eNB或家庭eNB。需要说明的是,eNB可以支持一个或多个(例如,三个)小区(其还称为扇区)。
用户设备UE:UE是LTE中通过eNB接入网络侧的设备,例如可以是手持用户设备、笔记本电脑或是其他可以接入网络的设备。
首先参见图1,图1是本发明实施例提供的一种控制信息传输系统的结构示意图,由图1所示,该控制信息传输系统包括基站110,以及一个或多个用户设备120,该用户设备可以为手机、平板电脑等能接入无线网络的通信用户设备。在本发明实施例中,基站110和用户设备120之间可以建立数据通信连接,实现数据传输,例如基站可以通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)向用户设备发送下行控制信息,用户设备可以通过物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)向基站发送上行数据。
目前,基站通过控制信道发送控制信息时,该控制信道是通过公共宽波束发送的,由于公共宽波束覆盖范围宽,但用户接收的功率低,导致可靠性低。针对该问题,本发明提出了一种控制信道设计方法,通过将控制信道承载的信息分为两个不同的波束进行发送,当基站需要向用户发送控制信息时,同时通过两个波束发送该控制信息,以提高信道传输可靠性,并且由于其中一个波束针对性强,可靠性高,所以可以极大地保证控制信道的接收成功率。
以下,对该方法进行详细说明。
首先对控制信道的设计方式进行详细说明。可参见图2、图3、图4和图5,图2是本发明实施例提供的一种控制信道结构划分示意图,图3是本发明实施例提供的一种第一类型波束发送示意图,图4是本发明实施例提供的一种用户 控制信息发送示意图,图5是本发明实施例提供的另一种用户控制信息发送示意图。
在本发明实施例中,控制信道的帧结构可以通过同时在时域和频域进行划分,从而划分为相互不重叠的时频位置,每一个时频位置对应一个独立的控制信息承载,基站在下发控制信息前首先为各个用户设备分配不同的时频位置,具体参见图2。控制信道的帧结构在频域的划分上,不同频段可采用不同的波束赋形技术从而其承载的信息可通过不同的波束进行发送。例如,第一频段可采用第一类型波束赋形;第二频段采用第二类型波束赋形。第一频段可以为一个子载波或者多个连续的子载波所在的频段;第二频段可以为一个子载波或者多个连续的子载波所在的频段。
可选地,在本发明的一个实施例中,该第一类型波束为宽波束,该第二类型波束为窄波束。窄波束可以是由所有天线共同波束赋形的不同波束方向的波束,不同窄波束赋形的加权系数不同,宽波束可以是由部分或所有天线共同波束赋形的不同波束方向的波束,不同宽波束赋形的加权系数也不相同。不同的窄波束可以在水平/垂直维度上具有不同的指向,以便于不同波束在波束域这个维度进行隔离。被不同窄波束覆盖的用户设备,可以在相同的时频资源上进行复用传输。
在本发明实施例中,该第一频段的时频资源,可以用于发送当前子帧调度的所有用户的控制信号,还可用于发送广播信号。其中,广播信号及各用户设备的控制信息分别使用不同的时频位置,具体参见图3;该第二频段的时频资源可用于向用户设备发送辅助的控制信号,从而当对于URLLC业务或其它对控制信道可靠性要求较高的业务,基站可使用第一频段的时频资源与第二频段的时频资源同时向用户设备发送控制信息,提高控制信道的接收质量,具体参见图4。具体地,基站在第二频段向用户设备发送控制信息时,使用与该用户设备对应的时频位置发送相应的控制信息。也就是说,对于一部分用户设备而言,其控制信息可仅承载于第一频段的时频资源;而对控制信息接收质量要求较高的另一部分用户而言,其控制信息除了承载在第一频段的时频资源以外,还在第二频段的时频资源承载相同的控制信息,实现控制信息的辅助发送。
举例说明,在本发明的一个示例中,某个子帧上,有三个用户设备需要调度,其中用户设备1和用户设备2为URLLC业务用户,用户设备3为eMBB 业务用户;由于URLLC业务用户对控制信道接收成功率要求高,所以对用户1和用户2采用第一类型波束加第二类型波束辅助的控制信道发送方法,也即在控制信道的第一频段的时频资源和第二频段的时频资源上同时发送用户设备1和用户设备2的控制信息,但用户1和用户2占用的第二频段的具体时频位置不同;由于用户设备3为eMBB用户,所以可对用户设备3仅采用第一类型波束发送方法,控制信息只占用第一频段的时频资源。整体发送图如图5所示。从而通过上述发送方式,可以保证URLLC业务的控制信道接收成功率。
下面再具体描述基于上述控制信道进行控制信息发送的具体流程。
参见图6,图6是本发明实施例提供一种控制信息发送方法的示意流程图,如图6所示,该方法可包括以下步骤:
S601、基站确定用户设备的控制信息。
在本发明实施例中,基站确定当前子帧调度的N个用户设备中的至少一个用户设备的控制信息,所述N为正整数。其中,该N个控制信息与该N个用户设备一一对应。
具体地,在本发明的一个实施例中,若该控制信道为PDCCH,该控制信息为DCI。
S602、基站确定控制信息所占的第一时频位置及第二时频位置。
在本发明实施例中,基站确定各个用户的控制信息所占的第一时频位置以及第二时频位置。
其中,该时频位置指示各个用户设备的各个控制信息发送时所使用的信道的时频位置,在本发明实施例中,该时频位置包括第一频段中的第一时频位置以及第二频段中的第二时频位置。
可选地,在本发明一个可能的实施例中,在确定所述控制信息所占的第一时频位置及第二时频位置之前,所述方法还包括:
根据预设条件从所述N个用户设备中确定第一用户集合及第二用户集合,所述第一用户集合包括所述至少一个用户设备,所述第二用户集合包括所述N个用户设备中除所述第一用户集合以外的其他用户设备;
采用第一类型波束向所述至少一个用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向所述至少一个用户设备发送所述第二时频 位置的所述控制信息,包括:
采用所述第一类型波束向所述第一用户集合内的用户设备发送所述第一时频位置的所述控制信息,以及采用所述第二类型波束向所述第一用户集合内的用户设备发送所述第二时频位置的所述控制信息。
可选地,在本发明另一个可能的实施例中,确定所述第二用户集合内的用户设备的所述控制信息所占的时频位置;其中,所述第二用户集合内的用户设备的所述控制信息所占的时频位置所在频段与所述第一时频位置所在频段相同;
采用所述第一类型波束向所述第二用户集合内的所述用户设备发送其对应的所述控制信息。
其中,该预设条件是指用于确定用户设备类型,从而进一步确定该用户设备的控制信息的发送方式的条件,从而根据该预设条件可以将用户设备划分为第一用户集合以及第二用户集合,当用户设备属于第一用户集合时,同时使用第一类型波束以及第二类型波束发送控制信息,当用户设备属于第二用户集合时,仅使用第一类型波束发送控制信息。
可以理解,通过对不同的用户设备的控制信息使用不同的控制信息发送方式,当用户设备的控制信息的接收准确率高时,使用第一类型波束和第二类型波束同时发送,以满足用户设备的需求,而当用户设备的控制信息的接收准确率没那么高时,可仅使用第一类型波束进行发送,提高信息传输效率。
可选地,在本发明的一个可能的实施例中,该预设条件可以为用户设备的当前应用场景。
具体地,在本发明的一个可能的实施例中,确定所述控制信息所占的第一时频位置及第二时频位置之前,所述方法还包括:
确定所述至少一个用户设备的当前应用场景;
采用第一类型波束向所述至少一个用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向所述至少一个用户设备发送所述第二时频位置的所述控制信息,包括:
当所述至少一个用户设备的当前应用场景为预设应用场景时,采用第一类型波束向所述至少一个用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向所述至少一个用户设备发送所述第二时频位置的所述控制 信息。
其中,每一用户设备的当前应用场景可以指的是该用户设备当前的业务应用场景,在本发明实施例中,该预设应用场景为可以为URLLC业务应用场景。从而当用户设备处于URLLC业务应用场景时,由于URLLC业务应用场景对可靠性要求较高,因此URLLC业务场景下同时使用第一类型波束和第二类型波束发送控制信息。从而当用户设备处于预设应用场景时,也即认为该用户设备为第一用户集合,此时使用第一类型波束和第二类型波束发送控制信息,而当用户设备不处于预设应用场景,例如eMBB业务用户,此时可认为该用户设备为第二用户集合,故仅使用第一类型波束发送控制信息。当然基于实际需要,eMBB或者mMTC场景下的用户设备,也可采用第二频段的时频资源辅助的方式,在第一频段的时频资源及第二频段的时频资源同时发送控制信息。本发明实施例不对此作具体限定。
举例说明,在本发明的一个示例中,在某个子帧上,有五个用户设备需要发送调度信息,其中用户设备1、用户设备2、用户设备3、用户设备4为URLLC业务用户,用户5为eMBB业务用户;由于URLLC业务用户对控制信道接收成功率要求高,所以对用户设备1、用户设备2、用户设备3、用户设备4采用宽波束加窄波束辅助的控制信道发送方法,而用户设备5仅采用宽波束发送控制信息。
可以理解,通过用户设备的当前应用场景来确定用户设备的控制信息的发送方式,使得控制信息的发送与应用场景相匹配。
可选地,在本发明的一个可能的实施例中,该预设条件可以为用户设备的优先级等级。
具体地,在本发明的一个可能的实施例中,确定所述控制信息所占的第一时频位置及第二时频位置之前,所述方法还包括:
确定所述至少一个用户设备的优先级等级;所述优先级等级通过用户设备优先级、调度优先级以及业务优先级中的一项或多项的组合确定;
采用第一类型波束向所述至少一个用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向所述至少一个用户设备发送所述第二时频位置的所述控制信息,包括:
当所述至少一个用户设备的预设优先级等级为预设优先级等级时,采用第 一类型波束向所述至少一个用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向所述至少一个用户设备发送所述第二时频位置的所述控制信息。
其中,用户设备的优先级等级是指用于确定发送用户控制信息的优先级等级,例如,高级用户的优先级等级高于一般用户。在本发明实施例中,可确定高级用户为预设优先级等级,从而当用户设备的等级为高级用户时,该用户设备的控制信息可使用第一类型波束和第二类型波束进行发送。
其中,业务优先级可以指:语音业务、数据业务(例如图像视频等),可以定义语音业务优先级高于数据业务优先级。调度优先级可以根据用户在之前一段时间内的平均速率、当前需要调度的数据量以及是否为重传等因素确定。例如,如果在过去的一段时间内平均速率很高,说明之前分配给这个用户很多资源,那该用户当前的优先级会降低。如果用户当前调度的数据量越大,则优先级越高。如果用户为重传用户,也优先级更高等等。使用多个参数组合来确定用户的优先级等级,将使得用户设备的控制信息的发送考虑到多种情景。
可以理解,通过不同的方式来确定用户设备的控制信息的发送方式,使得控制信息的发送更为灵活。
可选地,在本发明的一个可能的实施例中,确定所述控制信息所占的第二时频位置,包括:
确定所述至少一个用户设备初始接入时的第二类型波束方向;
根据所述至少一个用户设备的第二类型波束方向确定所述用户设备的第二时频位置;其中,占用同一第二时频位置的两个或以上的所述用户设备具有不同的第二类型波束方向以使同一第二时频位置的多个控制信息相互正交。
具体地,在本发明的一个实施例中,该多个控制信息通过空分的方式进行正交。可以理解,通过上述方式,可以使得具有不同的第二类型波束方向的用户设备的控制信息在使用第二频段中同一时频位置发送时互不干扰。
可选地,在本发明的一个可能的实施例中,确定所述控制信息所占的第二时频位置,包括:
确定所述至少一个用户设备初始接入时的第二类型波束方向;
确定所述至少一个用户设备的优先级;所述优先级包括用户设备优先级、调度优先级以及业务优先级中的一项或多项的组合;
根据所述至少一个用户设备的第二类型波束方向及优先级确定所述用户设备的所述控制信息所占的第二时频位置;其中,占用同一第二时频位置的两个或以上的所述用户设备具有不同的第二类型波束方向以使同一第二时频位置的多个所述控制信息相互正交;当两个或以上的所述用户设备的第二类型波束方向相同且预占第二时频位置也相同时,则采用所述第二类型波束发送所述优先级最高的所述用户设备的所述控制信息。
举例说明,在本发明的一个示例中,若第一类型波束为宽波束,第二类型波束为窄波束。若在某个子帧上,有五个用户设备需要发送调度信息,其中用户设备1、用户设备2、用户设备3、用户设备4为URLLC业务用户,用户5为eMBB业务用户。
由于URLLC业务用户对控制信道接收成功率要求高,所以对用户设备1、用户设备2、用户设备3、用户设备4采用宽波束加窄波束辅助的控制信息发送方法,由于基站最初配置用户设备1、用户设备2和用户设备3占用的第二频段的时频位置相同,用户设备2和用户设备3的波束发送方向也相同,用户设备4占用另外一个时频位置。用户设备1及用户设备2的窄波束方向不同,因此二者的控制信息可以承载在同一时频位置。由于用户设备2和用户设备3的时频位置和窄波束方向同时发生了冲突,因此选择优先级等级更高的用户设备2发送窄波束,用户3的控制信息只发送宽波束;
由于用户设备5为eMBB用户,所以可对用户设备5采用宽波束发送方法,控制信息只占用第一频段的时频资源。整体发送图如图7所示,图7是本发明实施例提供的又一种用户控制信息发送示意图。
在本发明实施例中,用户设备的波束在发送的过程中,由于方向可能发生变化,所以不同用户设备的波束可能相同。当不同用户设备所占用的窄波束子区域相同且窄波束方向也相同时,为了防止各用户设备所发送的控制信息之间干扰,此时可选择只发送各用户设备中优先级等级最高的用户设备的控制信息,而其它用户设备的控制信息可以只通过第一类型波束发送,也可以选择在该第二时频位置的下一个空闲时域发送,以保证控制信息的接收成功率。
可以理解,在不同用户设备所占用的第二时频相同且第二类型波束方向也 相同时,通过只发送优先级最高的用户设备的控制信息,可以保证该调度优先级最高的用户设备的控制信息的接收成功率,同时防止不同用户设备之间的控制信息的干扰,提高控制信息的接收准确性。
可选地,在本发明的一个可能的实施例中,当两个或以上的所述用户设备的第二类型波束方向相同且预占的第二时频位置也相同时,所述方法还包括:
向优先级非最高的所述用户设备发送其对应的控制信息,所述对应的控制信息通过所述预占第二时频位置的下一个空闲时域进行发送。
可选地,用户设备接收基站在第一时频位置发送的控制信息以及在第二时频位置发送的控制信息,包括:
所述用户设备通过所述第二时频位置的下一个空闲时域接收所述基站发送的控制信息。
在本发明实施例中,用户设备的波束在发送的过程中,由于方向可能发生变化,所以不同用户设备的波束可能相同。当不同用户设备所占用的窄波束子区域相同且窄波束方向也相同时,为了防止各用户设备所发送的控制信息之间干扰,此时可选择只发送各用户设备中调度优先级等级最高的用户设备的控制信息,而其它用户设备的控制信息可以只通过第一频段发送,也可以选择在该第二频段中的第二时频位置的下一个空闲时域发送,以保证控制信息的接收成功率。
可以理解,通过上述不同的控制信息发送方式,在有多个用户设备使用第二频段发送控制信息时,在上述不同的应用场景下,均可以保证不同用户设备的不同控制信息间互不干扰,保证信息的传输准确性。
在本发明实施例中,基站最初确定的各用户设备的时频位置将使得各用户设备发送控制信息时互不干扰。对于第二频段的时频资源来说,可以是分别位于不同的时频位置,也可以是位于相同的时频位置,当位于相同的时频位置时,各用户设备的第二类型波束方向不同,此时各用户设备通过第二频段发送控制信息时也互相不干扰。
S603、基站向用户设备发送指示信息。基站接收用户设备发送的指示信息。
其中,该指示信息用于指示所述用户设备所述控制信息的发送模式。
其中,该发送模式可以为第一类型波束发送模式,以及第一类型波束和第二类型波束发送模式。也即当该用户设备的控制信息将通过第一类型波束和第 二类型波束发送时,该指示信息指示的发送模式为第一类型波束和第二类型波束发送模式,而当该用户设备的控制信息仅通过第一类型波束发送时,该指示信息指示的发送模式为第一类型波束发送模式。
S604、用户设备根据指示信息切换到相应的接收模式。
可以理解,通过将用户设备的控制信息的发送模式提前发送给用户设备,从而使得用户设备在接收到该发送模式时,能准确地获取到控制信息。
S605、基站向用户设备发送控制信息所占的时频位置。用户设备接收基站发送的控制信息所占的时频位置。
在本发明实施例中,基站向所述至少一个用户设备发送所述控制信息所占的时频位置。其中,该时频位置包括第一时频位置。可选地,该时频位置也可以包括第二时频位置。
具体地,当选择第一类型波束发送控制信息时,该时频位置包括第一时频位置。
具体地,当选择第一类型波束和第二类型波束同时发送控制信息时,该时频位置包括第一时频位置和第二时频位置。
可以理解,通过将控制信息的时频位置发送给用户设备,从而使得用户设备可以通过该时频位置准确地接收控制信息。
S606、基站采用第一类型波束向用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向用户设备发送所述第二时频位置的所述控制信息。
具体地,基站采用第一类型波束向所述至少一个用户设备发送所述第一时频位置的所述控制信息,以及采用第二类型波束向所述至少一个用户设备发送所述第二时频位置的所述控制信息。
具体地,在本发明的一个实施例中,当基站确定所述N个控制信息在控制信道所占的时频位置后,可以通过广播信号的方式向各用户设备发送与各用户设备对应的时频位置信息。
S607、用户设备将从所述第一时频位置接收到的控制信息以及从所述第二时频位置接收到的控制信息进行分集合并处理获得所述控制信息。
在本发明实施例中,由于基站发送该控制信息时同时使用第一频段以及第二频段进行发送,所以用户设备将从第一频段接收到的信息以及从第二频段接 收到的信息进行分集合并处理获得该控制信息。提高控制信息的接收成功率。
可以看出,本实施例的方案中,基站在确定当前子帧调度的N个用户的至少一个用户的控制信息后,再确定该控制信息所占用的第一时频位置以及第二时频位置,并同时使用第一时频位置以及第二时频位置将该控制信息下发至用户设备,以使用户设备将从第一时频位置接收到的控制信息以及从第二时频位置接收到的控制信息进行分集合并处理得到控制信息,提高控制信道接收成功率,提升控制信道的接收信号质量,减少控制信道的误码率。
值得说明的是,该控制信道也可以为PUCCH,也即也可以将PUCCH的时频资源划分为两个不同频段,并采用不同的进行发送,但具体实现方式上将根据实际情况重新进行设计。
