Description

载波调度的方法及装置 技术领域
本申请涉及通信技术领域,尤其涉及一种载波调度的方法及装置。
背景技术
针对高频和低频上的多个载波成员(Carrier Component,CC,简称为载波)进行载波聚合来进行跨载波数据传输时,由于低频频谱对应路损小,因此低频上的CC作为主小区组(Primary Cell,PCell)是一个比较常见选择。按照现有技术,这一系统可以工作。但是存在下列一些潜在约束:
一般低频频谱资源有限,因此对应的NR(new radio,新无线)CC带宽一般较小(相对于高频的频谱,例如3.5GHz上的NR CC),这会导致物理下行控制信道(Physical Downlink Control Channel,PDCCH)资源有限,从而可能会导致PDCCH拥塞,从而影响系统性能。
且在现有的NR协议中,PCell或者PSCell(Primary Secondary Cell,主辅小区)都只能自调度,即其上面的数据传输PDSCH(Physical Downlink Shared CHannel,物理下行共享信道)/PUSCH(Physical Uplink Shared Channel,物理上行共享信道)只能通过自己CC上的PDCCH来调度,不能通过SCell(Secondary Cell Group,辅小区组)来调度他们的数据传输。
为了进一步提升上述系统性能,需要进行改进,允许其他载波CC来调度主小区上的数据传输。目前存在着无法通过其他载波调度主小区上的数据传输的技术问题。

具体实施方式
这里将详细地对示例性具体实施方式执行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性具体实施方式中所描述的实施方式并不代表与本申请的具体实施方式相一致的所有实施方式。相反,它们仅是与如所附 权利要求书中所详述的、本申请的一些方面相一致的方法和装置的例子。基于本申请中的具体实施方式,本领域技术人员在没有做出创造性劳动前提下获得的所有其他具体实施方式,都属于本申请的保护范围。
图1为本申请以下具体实施方式可能应用的通信系统的系统架构。该系统架构包括:基站A,用户终端B。
图2为本申请以下具体实施方式可能应用的通信系统的系统架构。该系统架构包括:用户终端A,用户终端B。
载波聚合(Carrier Aggregation,CA)是4G(the 4th generation mobile communication technology,第四代移动通信技术)/LTE(Long Term Evolution,长期演进通信系统)和5G(5th generation mobile networks,第五代移动通信技术)/NR系统的重要技术,其基本原理是在多个载波成员CC(为了描述简单,经常把载波成员简称为载波)上进行数据传输,以提高系统性能。载波聚合使用的场景至少有以下几种:
用于网络设备与终端设备之间的通信;
用于终端设备与终端设备之间的通信(例如设备到设备(Device to Device,D2D),车用无线通信技术(Vehicle to X,V2X)等场景)。
载波聚合按照数据传输方向可以细分为下行载波聚合(多个CC用于下行数据传输),上行载波聚合(多个CC用于上行数据传输)。数据传输指的是下行数据传输和/或上行数据传输,本申请中为了示例,只示例了PDSCH,但同样可以用于PUSCH,本申请不对此进行限定。
载波聚合主要有以下一些好处:
通过多个载波(CC)同时与一个终端进行通信,可以提升传输速率;
通过在多个CC之间灵活调度,可以有效地避免单个载波上业务符合过大,可以更好地平衡在多个CC之间取得较好的业务负载,提升系统整体性能和用户体验;
通过跨载波调度(即PDCCH在一个CC,其调度的数据传输PDSCH/PUSCH在另一个CC),可以减少控制信道拥塞引起的调度限制,提升传输性能。
载波聚合CA的好处是,通过跨载波调度(cross-carrier scheduling)可 有效地避免部分载波上PDCCH拥塞的问题。
图3是两个载波的载波聚合的示意图(以调度下行数据传输PDSCH为例),如图3所示,两个载波为CC0和CC1:
CC0上的数据传输是CC0上的PDCCH调度的(我们简称为自调度);
CC1上的数据传输是CC0上的PDCCH调度的(我们简称为跨载波调度,即CC0调度CC1)。
使用跨载波调度时,对应的DCI(Downlink control information,下行控制信息)中会有一个特殊的域载波指示域carrier indicator field(CIF),其对应的数值用于指示当前这个DCI调度的PDSCH对应的哪个载波CC。
CIF域如果不存在(不存在跨载波调度),则对应0bit长度;
CIF域如果存在(存在跨载波调度),则对应3 bits长度。
在NR协议中,自调度和跨载波调度的RRC(Radio Resource Control,无线资源控制)信令配置采用如下方式:
一个CC对应的配置信息IE(Information Element,消息元素)ServingCellConfig(服务小区配置)中含有一个RRC IE CrossCarrierSchedulingConfig(跨载波调度配置);
在上述IE中,配置此CC上的数据传输是自调度,还是跨载波调度(即需要其他CC上的PDCCH来调度自己):
配置参数own,表示自调度;
配置参数other,表示跨载波调度,同时还需要配置调度自己数据的PDCCH所在的CC编号(schedulingCellId),以及在CIF中自己载波所对应的编号(cif-InSchedulingCell)。
在现有的NR协议中,PCell或者PSCell都只能自调度,即其上面的数据传输PDSCH/PUSCH只能通过自己CC上的PDCCH来调度,不同通过SCell来调度他们的数据传输。
低频的频谱已经大量被用于2G(2-Generation wireless telephone technology,第二代移动通信技术)/3G(3-Generation wireless telephone technology,第三代移动通信技术)/4G等通信系统,相对较高的频谱(例如3.5GHz)目前较为宽裕,因此被广泛用于NR系统。由于频段较高,其覆 盖范围受到限制,因此低频频域用于NR具有很强的吸引力。
低频频谱路损小,覆盖范围大,可靠性更好;
部分以前系统(例如2G/3G/4G)的频带可以refarming(重耕)出来部署NR。
因此未来低频频谱上部署5G/NR系统将会是一个普遍现象。当高低频都部署NR时,一个同时使用多个频段的高效方法是使用载波聚合,即同时使用低频和高频上的CC来进行数据传输,一方面可以提高数据传输的可靠性,同时也能提高数据传输的速率,提升系统整体性能。
在NR中,控制信道(PDCCH)上传输DCI,DCI可以用来指示和调度对应数据传输(例如PDSCH,PUSCH)。假设跨载波调度(CC0上的控制信道调度CC1上的数据传输),则CC1传输数据,其对应的控制信道相关的配置也是CC1相关联,但是终端在监测PDCCH时,需要到CC0上来监测对应的DCI。
在NR中,控制信道的配置分为两层:
控制资源集CORESET(Control Resource Set);
在CORESET基础上配置有搜索空间SS(Search Space),其中搜索空间分为两类:
公共搜索空间CSS(Common Search Space):同一个小区中1个或多个或者所有终端设备共享的搜索空间;
用户搜索空间USS(UE-specific Search Space):特定UE自己的搜索空间。
其中,搜索空间Search space也可以被叫做搜索空间集合search space set,为了描述简单,可以简称为搜索空间Search space。
在现有的NR协议中,PCell或者PSCell都只能自调度,即其上面的数据传输PDSCH(Physical Downlink Shared CHannel,物理下行共享信道)/PUSCH(Physical Uplink Shared Channel,物理上行共享信道)只能通过自己CC上的PDCCH来调度,不能通过SCell(Secondary Cell Group,辅小区组)来调度他们的数据传输。
在本申请中,如无特殊说明,主小区包括PCell和PSCell。
本申请以下具体实施方式将详细描述如何允许其他载波来调度主小区上的数据传输,从而解决无法通过其他载波调度主小区上的数据传输的技术问题。
在本系统架构中,该示例通信系统可以是全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频段上的NR系统(New Radio based access to unlicensed spectrum,NR-U)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信,以及车用无线通信技术(Vehicle to X,V2X)等,本申请实施例也可以应用于这些通信系统。
该示例通信系统具体包括网络设备和终端,终端接入网络设备提供的移动通信网络时,终端与网络设备之间可以通过无线链路通信连接,该通信连接方式可以是单连接方式或者双连接方式或者多连接方式,但通信连接方式为单连接方式时,网络设备可以是LTE基站或者NR基站(又称为gNB基站),当通信方式为双连接方式时(具体可以通过载波聚合CA技术实现,或者多个网络设备实现)。本申请具体实施方式所涉及到的终端可以包括各 种具有无限通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS),终端设备(terminal device)等等。为方便描述,上面提到的设备统称为终端设备。
另外,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
应理解,在本申请具体实施方式中,“与A相应的B”表示B与A相关联,根据A可以确定B。但还应理解,根据A确定B并不意味着仅仅根据A确定B,还可以根据A和/或其它信息确定B。

在步骤110中,第一终端设备接收第一配置信息,第一配置信息用于指示第一终端设备配置至少第一小区和第二小区,其中,第一小区为主小区,第二小区为辅小区,第一小区的至少部分数据传输通过第二小区上传输的控制信息来调度。
其中,通过辅小区来调度主小区的数据传输,可以避免主小区控制信道拥塞从而导致主小区调度和主小区数据传输受限,提高载波聚合整体性能。主小区可以包含PCell,也可以包含PSCell。数据传输包括下行数据传输和/或上行数据传输。数据传输包括下行数据传输和/或上行数据传输,本申请的具体实施方式中为了示例,只描述了下行数据传输,但同样可以用于上行数据传输,本申请不对此进行限定。

可选的,该第一小区的至少部分数据传输还包括:
第一小区的至少部分数据传输通过第一小区自调度进行。
其中,当主小区位于较低频段时,由于路损较小,其对应的传输覆盖更好,鲁棒性更好,因此主小区同时可以进行自调度,可以有效地保障整个系统的覆盖以及传输可靠性。反之,如果只能通过相对较高频段的第二小区来进行跨载波调度,则会面临覆盖范围小,传输可靠性较低的问题。
可选的,该载波调度的方法还包括:
在步骤130中,第一终端设备接收第三配置信息,第三配置信息用于指示第一小区的至少部分数据传输可以通过第一小区自调度进行。

当第一搜索空间是用户搜索空间,且第一搜索空间支持DCI格式0_1和DCI格式1_1,并且第二小区已激活时,第一终端设备在第二小区上监测第一搜索空间对应的PDCCH candidate。
其中,当第一搜索空间是公共搜索空间CSS时,第一终端设备在第一小区上监测(monitor)第一搜索空间对应的物理下行控制信道候选集PDCCH candidate,公共搜索空间在低频的第一小区,可以有效地保障通信链路的可靠性和鲁棒性,同时为回退模式提供保障。可选的,第一小区对应的第一搜索空间是第一小区广播消息或系统信息指示的。可选的,第一小区对应的第一搜索空间是RRC信令指示的。
当第一搜索空间是用户搜索空间USS时,第一终端设备在已激活的第二小区上监测第一搜索空间对应的PDCCH candidate。在相对高频的第二小区传输USS中的PDCCH candidate,可以有效地降低第一小区上控制信道的拥塞概率,提高系统性能。若第二小区未激活,第一终端设备在第一小区上监测第一搜索空间对应的PDCCH candidate,若第二小区已激活,第一终端设备在第二小区上监测第一搜索空间对应的PDCCH candidate。从而在第二小区未激活前,仍然在第一小区监测USS,可以提高第一终端设备数据传输调度的概率,提高性能。当第二小区激活后,在第二小区上传输USS中的PDCCH candidate,可以降低第一小区控制信道的拥塞概率,提高性能。
当第一搜索空间是用户搜索空间USS,并且第一搜索空间支持DCI格式 0_1和DCI格式1_1,并且第二小区已激活时,第一终端设备在第二小区上监测第一搜索空间对应的PDCCH candidate。在相对高频的第二小区传输USS中的PDCCH candidate,可以有效地降低第一小区上控制信道的拥塞概率,提高系统性能。并且DCI格式0_1和1_1能支持的域更多,占用资源更多,在相对高频的第二小区传输DCI格式0_1和1_1,可以有效地降低第一小区上控制信道的拥塞概率,提高系统性能。
可选的,该步骤150可以包括以下步骤:
当第一搜索空间支持DCI格式0_0和DCI格式1_0,和/或第二小区未激活时,第一终端设备在第一小区上监测第一搜索空间对应的PDCCH candidate;和/或,
当第一搜索空间支持DCI格式0_1和DCI格式1_1且第二小区已激活时,第一终端设备在第二小区上监测第一搜索空间对应的PDCCH candidate。
当第一搜索空间支持DCI格式0_0和DCI格式1_0时,第一终端设备在第一小区上监测第一搜索空间对应的PDCCH candidate。DCI格式(format)0_0和1_0属于基本的DCI格式,也可以称为回退格式,其传输影响系统最基本的性能,因此在低频第一小区传输,可以有效地保障通信链路的可靠性和鲁棒性,同时为回退模式提供保障。
当第一搜索空间支持DCI格式0_1和DCI格式1_1时,第一终端设备在已激活的第二小区上监测第一搜索空间对应的PDCCH candidate。DCI format0_1和1_1能支持的域更多,占用资源更多,在相对高频的第二小区传输DCI format0_1和1_1,可以有效地降低第一小区上控制信道的拥塞概率,提高系统性能。若第二小区未激活,第一终端设备在第一小区上监测第一搜索空间对应的PDCCH candidate,若第二小区已激活,第一终端设备在第二小区上监测第一搜索空间对应的PDCCH candidate。在第二小区未激活前,仍然在第一小区监测DCI format0_1和1_1,可以提高第一终端设备数据传输调度的概率,提高性能。当第二小区激活后,在第二小区上传输DCI format0_1和1_1,可以降低第一小区控制信道的拥塞概率,提高性能。
当第一搜索空间支持的最大聚合等级(aggregation level)大于或者大于等于第一门限时,第一终端设备在第一小区上监测第一搜索空间对应的 PDCCH candidate。大聚合等级的PDCCH主要是为了保证覆盖范围,因此在低频第一小区传输,可以有效地保障通信链路的可靠性和鲁棒性,同时为回退模式提供保障。
可选的,该步骤150可以包括以下步骤:
当第一搜索空间支持的最大聚合等级(aggregation level)大于或者大于等于第一门限时,第一终端设备在已激活的第二小区上监测第一搜索空间对应的PDCCH candidate。大聚合等级的PDCCH占用资源较多,因此在相对高频的第二小区传输USS中的PDCCH candidate,可以有效地降低第一小区上控制信道的拥塞概率,提高系统性能。若第二小区未激活,第一终端设备在第一小区上监测第一搜索空间对应的PDCCH candidate,若第二小区已激活,第一终端设备在第二小区上监测第一搜索空间对应的PDCCH candidate。在第二小区未激活前,仍然在第一小区监测,可以提高第一终端设备数据传输调度的概率,提高性能。当第二小区激活后,在第二小区上传输聚合等级大的PDCCH candidate,可以降低第一小区控制信道的拥塞概率,提高性能。
当第一搜索空间支持的最大聚合等级(aggregation level)小于或者小于等于第一门限时,第一终端设备在第一小区上监测第一搜索空间对应的PDCCH candidate。小聚合等级的PDCCH占用资源少,因此在低频第一小区传输,可以有效地降低控制信道资源碰撞概率,降低控制信道拥塞概率。
当第一搜索空间支持的最大聚合等级(aggregation level)小于或者小于等于第一门限时,第一终端设备在已激活的第二小区上监测第一搜索空间对应的PDCCH candidate。在相对高频的第二小区传输部分搜索空间的PDCCH candidate,可以有效地降低第一小区上控制信道的拥塞概率,提高系统性能。若第二小区未激活,第一终端设备在第一小区上监测第一搜索空间对应的PDCCH candidate,若第二小区已激活,第一终端设备在第二小区上监测第一搜索空间对应的PDCCH candidate。在第二小区未激活前,仍然在第一小区检测,可以提高第一终端设备数据传输调度的概率,提高性能。当第二小区激活后,在第二小区上传输部分搜索空间的PDCCH candidate,可以降低第一小区控制信道的拥塞概率,提高性能。
