Description

一种控制信息发送方法、接收方法、发送设备和接收设备
本申请要求于2017年09月11日提交中国专利局、申请号为201710814530.3、申请名称为“一种控制信息发送方法、接收方法、发送设备和接收设备”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
本申请涉及通信技术领域,尤其涉及一种控制信息发送方法、接收方法、发送设备和接收设备。
背景技术
为了应对未来爆炸性的移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景,第五代(the fifth generation,5G)移动通信系统应运而生。国际电信联盟(International Telecommunication Union,ITU)为5G以及未来的移动通信系统定义了高可靠低时延通信(Ultra Reliable and Low Latency Communications,URLLC)业务场景。
不同业务对移动通信系统的需求不同,如何更好地同时支持多种不同业务的数据传输需求,是当前5G移动通信系统所需要解决的技术问题。例如,如何同时支持URLLC业务与其他业务就是当前5G移动通信系统的讨论热点之一。
由于URLLC业务的数据的突发性,为了提高系统资源利用率,接入网设备通常不会为URLLC业务的下行数据传输预留资源。当URLLC业务数据到达接入网设备时,若此时没有空闲的时频资源时,且如果等待已调度业务数据传输完成之后再调度URLLC业务数据,URLLC业务数据的传输时延则会变大,从而无法满足URLLC业务的超短时延需求。因此,接入网设备可以采用如图1抢占(preemption)的方式传输URLLC业务数据。这里的抢占是指接入网设备在已经分配的用于传输其它数据的时频资源上选择部分或全部的时频资源用于传输URLLC业务数据,即接入网设备在用于传输URLLC业务数据的时频资源上不发送其它的业务数据。
此外,用于传输其它数据的时频资源上的一部分资源还可能用于传输其它信号或者该一部分资源可能被接入网设备预留做其它用途。当接入网设备调度URLLC业务数据的传输时,为了实现高效的URLLC业务数据传输,URLLC业务数据的传输中是否需要占用或者避让这些资源,以实现URLLC业务数据高质量传输与其他业务之间的平衡是亟需解决的问题。
发明内容
本申请提供一种控制信息发送方法、接收方法、发送设备和接收设备,用以解决现有技术中存在的如何实现URLLC业务数据高质量传输与其他业务之间的平衡的问题。
为解决上述问题,本申请提供了如下技术方案:
第一方面,本申请提供了一种控制信息发送方法,包括:发送设备确定控制信息;发送设备向接收设备发送控制信息;其中,控制信息对应的资源集合(即该控制信息所能出现的位置)与第一时频资源重叠,当控制信息的类型为第一控制信息类型时, 第一时频资源能够用于承载控制信息;或者,当控制信息的类型为第一控制信息类型时,控制信息对应的搜索空间(即接收设备和发送设备之间事先约定的一些可能用于承载控制信息的时频资源,由可能承载控制信息的时频资源组成的时频资源组通常叫做搜索空间)与第一时频资源重叠;或者,控制信息用于指示接收设备在第二时频资源(其中,第二时频资源为接收设备可以接收下行数据的时频资源)上接收数据,第二时频资源与第一时频资源重叠,控制信息还用于指示第一时频资源承载数据。
本申请实施例提供一种控制信息发送方法,由于接收设备在检测到控制信息之前,接收设备并不知道是否有控制信息发送,以及发送设备向接收设备发送控制信息的情况下,该控制信息由哪个时频资源承载,因此,本申请通过发送设备向接收设备发送控制信息,并在控制信息对应的资源集合与第一时频资源重叠时,利用控制信息的类型(例如,第一控制信息类型)来向接收设备指示第一时频资源上可以承载控制信息,这样接收设备便可以确定在第一时频资源上寻找或者搜索该接收设备对应的控制信息,从而避免了在多个可能承载控制信息的时频资源上寻找控制信息,其次,接收设备通过控制信息向发送设备指示第一时频资源上是否承载数据,这样接收设备在接收到在接收到控制信息之后,便可以根据控制信息的指示在第一时频资源上接收数据。
结合第一方面,在第一方面的第一种可能的实现方式中,在发送设备确定控制信息之前,本申请实施例提供的方法还包括:发送设备向接收设备发送第一信息;其中,第一信息用于指示第一时频资源为保留资源,或者,第一信息用于指示第一时频资源不能用于承载信号,或者,第一信息用于指示第一时频资源可以不用于承载发送给接收设备的信号,或者,第一信息用于指示第一时频资源可以不用于承载发送给接收设备的数据和控制信息中的至少一项。通过向接收设备指示保留资源,或者,第一信息用于指示第一时频资源不能用于承载信号,或者,第一信息用于指示第一时频资源可以不用于承载发送给接收设备的信号,或者,第一信息用于指示第一时频资源可以不用于承载发送给接收设备的数据和控制信息中的至少一项,这样接收设备便确定需要避开第一时频资源,因此后续接收设备在接收到控制信息之后,便可以根据控制信息所满足的条件确定第一时频资源上是否承载数据或者信号,以确定是需要占用第一时频资源还是需要避开第一时频资源。可以理解的是在发送设备向接收设备发送第一信息之前或发送第一控制信息的同时,发送设备通过无线资源控制(radio resource control,RRC)信令、媒体接入控制(medium access control,MAC)信令和物理控制信令中的至少一个,向接收设备配置第一时频资源。该可能的设计中的信令的实现方式可参考下文,此处不再赘述。
结合第一方面或第一方面的第一种可能的实现方式中,在第一方面的第二种可能的实现方式中,本申请提供的方法还包括:控制信息对应的资源集合与第一时频资源重叠,当控制信息的类型为第二控制信息类型时,第一时频资源不能用于承载控制信息;或者,当控制信息的类型为第二控制信息类型时,控制信息对应的搜索空间与第一时频资源不重叠。通过在控制信息对应的资源集合与第一时频资源重叠时,利用控制信息的类型为第二控制信息类型来向接收设备指示第一时频资源不能用于承载控制信息,这样接收设备便可以在控制信息对应的资源集合中除第一时频资源之外的其余时频资源上搜索控制信息。此外,利用控制信息的类型为第二控制信息类型向接收设 备指示控制信息对应的搜索空间与第一时频资源不重叠,这样接收设备便可以知道第一时频资源上不承载控制信息以及确定控制信息对应的搜索空间中具体承载控制信息的时频资源的位置。

具体实施方式
需要说明的是,本申请中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请中“的(英文:of)”,相应的“(英文corresponding,relevant)”和“对应的(英文:corresponding)”有时可以混用,应当指出的是,在不强调其区别时,其所要表达的含义是一致的。
本申请中,“至少一个指一个或者多个。多个”是指两个或两个以上。“和/或”,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的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a-b,a-c,b-c,或a-b-c,其中a,b,c可以是单个,也可以是多个。另外,为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。例如,第一时频资源和第二时频资源仅仅是为了区分不同的时频资源,并不对其先后顺序进行限定。

本申请实施例结合发送设备和接收设备描述了各个实施例,其中,发送设备可以为网络设备和终端设备中的任一个,接收设备可以为网络设备和终端设备中的另一个,例如,在本申请实施例中,发送设备以网络设备(例如,基站)为例,接收设备可以为终端设备(例如,用户设备)为例;或者,发送设备可以为终端设备(例如,UE),接收设备可以为网络设备(例如,基站)。

作为示例,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。

另外,在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的传输资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信。该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小和发射功率低的特点,适用于提供高速率的数据传输服务。
本申请实施例提供的方法和装置,可以应用于终端设备或网络设备,该终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层,以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit,CPU)、内存管理单元(memory management unit,MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统,例如,Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、以及即时通信软件等应用。并且,在本申请实施例中,传输信号的方法的执行主体的具体结构,本申请实施例并未特别限定,只要能够通过运行记录有本申请实施例的传输信号的方法的代码的程序,以根据本申请实施例的传输信号的方法进行通信即可,例如,本申请实施例的无线通信的方法的执行主体可以是终端设备或网络设备,或者,是终端设备或网络设备中能够调用 程序并执行程序的功能模块。
此外,本申请实施例的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如,计算机可读介质可以包括,但不限于:磁存储器件(例如,硬盘、软盘或磁带等),光盘(例如,压缩盘(compact disc,CD)、数字通用盘(digital versatile disc,DVD)等),智能卡和闪存器件(例如,可擦写可编程只读存储器(erasable programmable read-only memory,EPROM)、卡、棒或钥匙驱动器等)。另外,本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于,无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
在当前讨论中,一个共识是URLLC业务数据传输可以占用资源,例如其它数据和/或信号所使用的时频资源,但是,其它数据和/或信号有可能是非常重要并且不希望被占用的,因此URLLC业务数据传输如何占用或者避开资源是需要解决的问题。需要说明的是,一个URLLC业务数据传输可以包含调度该业务的控制信息传输以及承载该业务数据的数据信道传输等。
针对上述问题,本申请实施例提出了一种控制信息的发送方法和一种控制信息接收方法以及相应的发送设备和接收设备。
本申请实施例中的一种控制信息的发送方法可以由发送设备或者应用于发送设备中的通信装置(例如,芯片)执行,一种控制信息接收方法可以由接收设备或者应用于接收设备中的通信装置(例如,芯片)执行。下述实施例将以一种控制信息的发送方法由发送设备作为执行主体,以一种控制信息接收方法由接收设备作为执行主体为例。可以理解,下述实施例中所有由发送设备执行的过程均可以由应用于终端设备中的芯片执行,所有由接收设备执行的过程可以由应用于接收设备中的芯片执行。
如图3所示,本申请提供的控制信息的发送方法,包括:
S101、发送设备确定控制信息。其中,控制信息对应的资源集合与第一时频资源重叠,当控制信息的类型为第一控制信息类型时,第一时频资源能够用于承载控制信息;或者,当控制信息的类型为第一控制信息类型时,控制信息对应的搜索空间与第一时频资源重叠;或者,控制信息用于指示接收设备在第二时频资源上接收数据,第二时频资源与第一时频资源重叠,控制信息还用于指示第一时频资源承载数据。
本申请中控制信息对应的资源集合可以为:包括控制信息所在的时频资源的时频资源集合,也可以理解为包括部分或者全部控制信息对应的搜索空间所在时频资源的时频资源集合,还可以理解为用于发送所述控制信息的时频资源集合。控制信息对应的一个资源集合包括一个或者多个时频资源。资源集合的一个时频资源在时域上位于一个或者多个时域单位,例如时域符号或者时隙。资源集合的一个时频资源在频域上位于一个或者多个频域单位,例如资源块(resource block,RB)或者资源块组(resource block group,RBG)。
在接收设备接收该控制信息之前,资源集合由发送设备为接收设备配置。在完成资源集合的配置之后,接收设备在该资源集合上监测(monitor)发送设备发送的控制信息,接收设备接收发送设备发送的控制信息。资源集合又可以称为控制资源集合 (Control resource set)。
其中,控制信息对应的资源集合与第一时频资源重叠可以理解为:控制信息对应的资源集合包括第一时频资源的部分或者全部,也可以理解为控制信息对应的资源集合中至少一个资源粒子(resource element,RE)包括在第一时频资源内,或者说,第一时频资源中至少一个RE包括在控制信息对应的资源集合内。
其中,控制信息对应的搜索空间可以为接收设备和发送设备事先约定或者协商、默认的一些可以承载控制信息的时频资源。具体地,控制信息对应的搜索空间包含以下因素:控制信息的一个或者多个聚合等级(Aggregation level),每个聚合等级对应的控制信息候选的个数,以及每个控制信息候选对应的控制信道元素(Control channel element,CCE)的个数。如图4所示,发送设备和接收设备事先约定对应一个聚合等级如图4所示的候选1、候选2、候选3、候选4、以及候选5中的至少一个用于承载控制信息,这样接收设备在接收发送设备发送的信息时,便可以从上述所示的候选1、候选2、候选3、候选4、以及候选5中寻找或检测到控制信息。图4中的每一个候选包含的CCE个数相同。作为示例而非限定,图4中黑色粗线框内的时频资源为发送设备为接收设备配置控制信息对应的资源集合,图4中虚线框内候选1至候选5为控制信息对应的搜索空间。
如图5所示,控制信息对应的搜索空间与第一时频资源重叠可以理解为:第一时频资源属于发送设备和接收设备之间约定或者协商的搜索空间对应的时频资源中的一个时频资源,或者,第一时频资源的一部分属于发送设备和接收设备之间约定或者协商的搜索空间对应的时频资源中的一个时频资源。
也可以理解为:第一时频资源属于发送设备和接收设备之间约定或者协商的可用于承载控制信息的一个候选对应的时频资源中的一个时频资源,或者,第一时频资源的一部分属于发送设备和接收设备之间约定或者协商的可用于承载控制信息的一个候选对应的时频资源中的一个时频资源。或者说,第一时频资源中至少一个RE包括在控制信息对应的一个候选内,或者,控制信息对应的一个候选内包括有第一时频资源中至少一个RE。
还可以理解为:第一时频资源属于发送设备和接收设备之间约定或者协商的可用于承载控制信息的一个CCE对应的时频资源中的一个时频资源,或者,第一时频资源的一部分属于发送设备和接收设备之间约定或者协商的可用于承载控制信息的一个CCE对应的时频资源中的一个时频资源。或者说,第一时频资源中至少一个RE被控制信息对应的一个CCE包括,反之亦然。
S102、发送设备向接收设备发送控制信息。
S103、接收设备从发送设备处接收控制信息。
本申请实施例提供一种控制信息发送方法,由于接收设备在检测到控制信息之前,接收设备并不知道是否有控制信息发送,以及发送设备向接收设备发送控制信息的情况下,该控制信息由哪个时频资源承载,因此,本申请通过发送设备向接收设备发送控制信息,并在控制信息对应的资源集合与第一时频资源重叠时,利用控制信息的类型(例如,第一控制信息类型)来向接收设备指示第一时频资源上可以承载控制信息,这样接收设备便可以确定在第一时频资源上寻找或者搜索该接收设备对应的控制信 息,从而避免了在多个可能承载控制信息的时频资源上寻找控制信息,其次,接收设备通过控制信息向发送设备指示第一时频资源上是否承载数据,这样接收设备在接收到在接收到控制信息之后,便可以根据控制信息的指示在第一时频资源上接收数据。
作为一种可能的实现方式,如图6所示,本申请在步骤S101之前还包括:
S104、发送设备向接收设备发送第一信息;其中,第一信息用于指示第一时频资源为保留资源,或者,第一信息用于指示第一时频资源不能用于承载信号,或者,
第一信息用于指示第一时频资源可以不用于承载发送给接收设备的信号,或者,
第一信息用于指示第一时频资源可以不用于承载发送给接收设备的数据和控制信息中的至少一项。
可以理解的是,第一时频资源可以不用于承载发送给接收设备的数据和控制信息中的任一项表示:第一时频资源可以不用于承载发送给接收设备的数据,或者可以不用于承载发送给接收设备的控制信息,或者可以不用于承载发送给接收设备的数据和控制信息。即发送设备确定第一时频资源为可以不承载数据和控制信息中的任一项的时频资源,这样发送设备在发送控制信息之前,根据是否满足预设条件再确定第一时频资源可以承载控制信息,或者,再确定第一时频资源不可以承载控制信息;发送设备在向接收设备发送数据之前,根据控制信息是否满足预设条件,然后再确定第一时频资源承载数据,或者,再确定第一时频资源不承载数据。类似地,接收设备确定第一时频资源为可以不承载数据和控制信息中的任一项的时频资源,这样接收设备在接收控制信息之前或者接收控制信息时,根据是否满足预设条件再确定第一时频资源可以承载控制信息,或者,再确定第一时频资源不可以承载控制信息;接收设备接收数据,根据是否满足预设条件再确定第一时频资源承载数据,或者,再确定第一时频资源不承载数据。
具体的,发送设备可以向接收设备发送配置信息,该配置信息中携带发送设备为接收设备配置的第一时频资源信息,该配置信息可以通过无线资源控制(Radio resource control,RRC)信令或者媒体接入控制(Mediu/Media Access Control,MAC)信令或者物理层控制信令发送给接收设备。这样可以提供最好的灵活性,根据每个接收设备的需求采用相应的信令,逻辑简单易于实现。
进一步地,该配置信息可以是接收设备专用的,即发送一个接收设备的;也可以是一组接收设备公用的,即发送给一组接收设备的。前者的好处是灵活简便,但是当小区内接收设备较多的时候,用于配置信息的开销较大。后者的好处是节省开销,但是,当小区内接收设备较少时,系统复杂度较高。
在实际过程中,控制信息的传输使用资源集合中的时频资源。除此以外,资源集合中的时频资源还可以不用于承载信号,例如该时频资源为保留资源,保留给其它紧急业务或者信号(但实际没有发送)的时频资源,或者,用于空置以便于发送设备或者接收设备测量信道(如,相邻小区的信号或者干扰)等。资源集合中的时频资源还可以不用于承载发送给接收设备的信号,例如该时频资源用于承载发送给其它接收设备的信号(如,用于其它接收设备测量的参考信号或者用于指示其它接收设备的信令)。资源集合中的时频资源还可以不用于承载发送个接收设备的控制信息,例如用于承载发送给该接收设备的用于测量的参考信号或者用于解调的参考信号等。
S105、接收设备接收发送设备为接收设备发送的第一信息。
具体的,接收设备可以通过RRC信令或者MAC信令或者物理层控制信令接收发送设备配置的第一时频资源。
作为另一种可能的实现方式,本申请中步骤S101还包括:
控制信息对应的资源集合与第一时频资源重叠,当控制信息的类型为第二控制信息类型时,第一时频资源不能用于承载控制信息;或者,
当控制信息的类型为第二控制信息类型时,控制信息对应的搜索空间与第一时频资源不重叠。
作为本申请实施例的另一示例,第一时频资源与资源集合重叠,第一时频资源至少为资源集合中可以不用于承载信号,或者,可以不用于承载发送给接收设备的信号,或者,不用于承载发送给接收设备的控制信息的时频资源。一种情况下,控制信息的传输不可以使用第一时频资源,或者,第一时频资源不可以承载控制信息,或者,控制信息对应的搜索空间与第一时频资源不重叠。例如,该控制信息用于普通优先级数据传输,或者,该控制信息用于其它用途(例如,初始随机接入、资源激活等)且该控制信息的优先级不高于第一时频资源原本的用途,例如,该第一时频资源原本用于承载紧急数据A,且该控制信息的优先级低于紧急数据A。
在又一种情况下,控制信息的传输可以使用第一时频资源,或者,第一时频资源可以承载控制信息,或者,控制信息对应的搜索空间与第一时频资源重叠。例如,该控制信息用于传输可靠性和/或传输时延较高的数据传输,或者,该控制信息用于优先级高于第一时频资源的原有使用目的数据传输,或者,该控制信息用于其它功用(例如,小区切换,紧急信令传输等)且该控制信息的优先级高于第一时频资源的原有使用目的。
在一个例子中,上述一种情况下,控制信息可以是第一控制信息类型,或者,在上述有一种情况下,控制信息是第一控制信息类型。在又一个例子中,在上述一种情况下,控制信息可以是第二控制信息类型,而在上述又一种情况下,控制信息是第一控制信息类型。
控制信息可以用于指示接收设备在第二时频资源上接收数据。为了便于指示,被指示的第二时频资源通常在时域上位于一个或者若干个时域单位,例如时域符号或者时隙或者子帧,在频域上位于一个或者多个频域单位,例如RB或者RBG或者子带(subband)。因此,第二时频资源通常大于等于实际中用于承载数据的时频资源。换句话说,除此以外,第二时频资源中的时频资源还可以不用于承载信号,例如该时频资源用于空置以便于发送设备或者接收设备测量信道(如,相邻小区的信号或者干扰)或者预留给其它紧急业务或者信号(但实际没有发送)等。第二时频资源中的时频资源还可以不用于承载发送给接收设备的信号,例如该资源用于承载发送给其它接收设备的信号(如,用于其它接收设备测量的参考信号或者用于指示其它接收设备的信令)。第二时频资源中的时频资源还可以不用于承载发送个接收设备的控制信息,例如用于承载发送给该接收设备的用于测量的参考信号或者用于解调的参考信号等。
作为本申请实施例的一个示例,第二时频资源与第一时频资源重叠,第一时频资源至少为第二时频资源中可以不用于承载信号,或者,可以不用于承载发送给接收设 备的信号,或者,不用于承载发送给接收设备的数据的时频资源。一种情况下,控制信息用于指示接收设备第一时频资源不承载数据,发送设备不使用第一时频资源向接收设备发送数据。例如,该数据为普通优先级数据,或者,该数据的优先级不高于第一时频资源的原有使用目的(例如,用于承载测量参考信号,用于测量干扰等)。在又一种情况下,控制信息用于指示接收设备第一时频资源承载数据,发送设备使用第一时频资源向接收设备发送数据。例如,该数据的传输对可靠性和/或传输时延要求较高,或者,该数据的优先级高于第一时频资源的原有使用目的(例如,用于承载测量参考信号,用于测量干扰等)。
第一时频资源可以由发送设备和接收设备之间约定或者协商的,也可以在出厂前预设在发送设备和接收设备中。例如,第一时频资源可以是用于承载公共信号或者系统信号的时频资源。
如图7所示,控制信息对应的搜索空间与第一时频资源不重叠可以理解为:第一时频资源不属于发送设备和接收设备之间约定或者协商的搜索空间对应的时频资源中的一个时频资源,或者,不属于约定或者协商的可用于承载控制信息的一个候选对应的时频资源中的一个时频资源,或者,不属于约定或者协商的可用于承载控制信息的一个CCE对应的时频资源中的一个时频资源。
在一个示例中,发送设备向接收设备发送配置信息,配置第一时频资源。该第一时频资源是一个连续的时频资源,该时频资源可以不用于承载任何信号,该配置信息可以是RRC信令或者物理层控制信息。
具体地,该第一时频资源可以承载控制信息或者不可以承载控制信息,或者,该第一时频资源可以承载数据或者不承载数据。或者,该第一时频资源与资源集合重叠的时频资源可以承载控制信息或者不可以承载控制信息,或者,该第一时频资源与第二时频资源重叠的时频资源可以承载数据或者不承载数据。发送设备为了更好地支持紧急信号以及更好地支持前向兼容性而预留资源。当出现高优先级数据传输需求时,发送设备可以利用本申请实施例的方案半静态或者动态的使用这些预留资源,从而有效提高高优先级数据的传输可靠性并尽量减小高优先级数据的传输时延。
在一个示例中,发送设备向接收设备发送配置信息,配置第一时频资源。该配置信息可以是RRC信令或者MAC信令。该第一时频资源用于承载零功率(zero power,ZP)信号,该第一时频资源周期地在时域上出现。
具体地,该第一时频资源与资源集合重叠的时频资源可以承载控制信息或者不可以承载控制信息,或者,该第一时频资源与第二时频资源重叠的时频资源可以承载数据或者不承载数据。
发送设备为了让一些接收设备避让开一下发送给其它接收设备的信号或者为了让该一些接收设备测量邻小区干扰等,通常情况下,发送设备会为该一些接收设备配置用于承载零功率信号的时频资源。一方面,当出现高优先级数据传输需求时,发送设备可以利用本申请实施例的方案半静态或者动态的使用这些用于承载零功率信号的时频资源,有效提高高优先级数据的传输可靠性并尽量减小高优先级数据的传输时延。
另一方面,发送设备决定向接收设备选择发送什么信号,如果该零功率信号是为了让一些接收设备避让开一下发送给其它接收设备的信号,发送设备用高优先级接收 设备的数据代替低优先级接收设备的数据或者参考信号,而后发送设备可以为低优先级接收设别重新传输受影响的数据或者参考信号。如果该零功率信号是为了让一些接收设备测量邻小区干扰等,那么发送设备用高优先级接收设备的数据代替零功率信号,虽然测量结果会受到影响,但是这些结果最终是汇报给发送设备使用的,发送设备知道这些结果不准确,可以改使用历史结果或者调度接收设备重新测量等,不会对测量的接收设备产生不可挽回的影响。
在另一个示例中中,发送设备向接收设备发送配置信息,配置第一时频资源。该配置信息可以是RRC信令或者MAC信令。该第一时频资源用于承载发送给接收设备的参考信号。进一步地,该参考信号为信道状态信息参考信号(Channel state information reference signal,CSIRS)该第一时频资源周期地在时域上出现。
具体地,该第一时频资源与资源集合重叠的时频资源可以承载控制信息或者不可以承载控制信息,或者,该第一时频资源与第二时频资源重叠的时频资源可以承载数据或者不承载数据。这种情况下,可以是一个接收设备的高优先级数据传输抢占了自己的参考信号所在的时频资源。或者说,如果伴随该参考信号传输的是该接收设备的普通数据传输,那么该普通数据不能占用参考信号所在的时频资源。如果伴随该参考信号传输的是该接收设备的高优先级数据,那么该高优先级数据可以占用参考信号所在的时频资源。发送设备随后会通过再传输参考信号等避免由此产生的不良影响。在这种实施方式下可以提高时频资源利用的灵活性,更大程度地保证高优先级数据传输的可靠性和时延。进一步地,该CSIRS可以是用于信道状态信息获取的CSIRS。该CSIRS还可以是用于波瓣管理等的CSIRS。相对而言,信道状态信息测量的不准确可能不能导致链路失败等结果,因此限制该CSIRS仅为用于信道状态信息获取的CSIRS可以降低由于占用参考信号产生的影响。而用于波瓣管理的CSIRS可能会发送给大于一个用户,占用用于波瓣管理的CSIRS的时频资源产生的影响大于仅占用用于信道状态信息获取的CSIRS。但是,为高优先级数据提供更多的传输资源可以有效保障高优先级数据的传输可靠性。占用哪一种或者哪些种参考信号的传输资源用以传输高优先级数据是发送设备的平衡决策。为发送设备提供更多的调度可能性可以有效增强发送设备支持高优先级数据传输的鲁棒性。
在一个例子中,发送设备向接收设备发送配置信息,配置第一时频资源。该配置信息可以是RRC信令或者物理层控制信令。该第一时频资源用于承载参考信号。进一步地,该参考信号为解调参考信号(Demodulation reference signal,DMRS)。该DMRS可以是发送设备发送给接收设备的,也可以是发送给其它接收设备的。具体地,该第一时频资源可以承载控制信息或者不可以承载控制信息,或者,可以承载数据或者不承载数据。或者,该第一时频资源与资源集合重叠的时频资源可以承载控制信息或者不可以承载控制信息,或者,该第一时频资源与第二时频资源重叠的时频资源可以承载数据或者不承载数据。占用DMRS的时频资源可能会导致与DMRS相应的数据或者控制信息解调失败。但是,如果该与DMRS相应的数据或者控制信息本身所在的资源被发送设备用来发送高优先级数据,那么仅发送DMRS就几乎没有什么作用了。类似前一个例子中关于CSIRS的分析,支持高优先级数据占用DMRS可以为发送设备提供更多的调度可能性可以有效增强发送设备支持高优先级数据传输的鲁棒性。
需要说明的是,资源集合与第二时频资源可以重叠也可以不重叠。第一时频资源可以既与资源集合重叠也与第二时频资源重叠。因此,第一时频资源可以用于承载控制信息,或者,不可以用于承载控制信息。第一时频资源不用于承载控制信息时,可以用于承载数据,或者,不用于承载数据。
此外,还需要说明的是,接收设备在接收到控制信息之前并不确知资源集合或者搜索空间上是否承载有控制信息,而是在搜索空间的候选上逐个检测(detect)以确定每个可能用于承载控制信息的候选上是否承载有控制信息。因此,第一时频资源不可以承载控制信息,则第一时频资源不承载控制信息。而,第一时频资源可承载控制信息意味着,实际上,第一时频资源上可能承载了控制信息,也可能并没有承载控制信息。第一时频资源可以承载或者不可以承载控制信息,相应地,接收设备在第一时频资源上检测控制信息或者不检测控制信息。
而接收设备在接收数据的时候,控制信息向接收设备指示第二时频资源上承载有数据,进一步地,控制信息向接收设备指示第一时频资源承载数据,或者,指示第一时频资源上不承载数据。第一时频资源承载或者不承载数据,相应地,接收设备在第一时频资源接收或者不接收数据。
第一时频资源可以不用于承载信号,或者,该第一时频资源可以不用于承载发送给接收设备的信号,或者,该第一时频资源可以不用于承载发送给接收设备的数据和控制信息中的任一项。第一时频资源是否可以承载控制信息可能会影响控制信息对应的候选的时频资源位置。
如图5所示,第一时频资源与资源集合重叠,第一时频资源可以承载控制信息。具体地,第一时频资源与候选1重叠的时候,即候选1(或者说控制信息对应的搜索空间、候选1对应的CCE)的时频资源包含第一时频资源。如图7所示,第一时频资源与资源集合不重叠,第一时频资源不可以承载控制信息。具体地,第一时频资源在候选1之外,即候选1(或者说搜索空间、候选1对应的CCE)的时频资源不包含第一时频资源。如果发送设备选择了候选1为接收设备发送控制信息,那么在前一种情况下,第一时频资源可以承载控制信息且第一时频资源承载了控制信息;在后一种情况下,第一时频资源不可以承载控制信息,实际上也没有承载控制信息。即,如果发送设备选择了候选1为接收设备发送控制信息,候选1与第一资源相邻,第一时频资源是否可以承载控制信息实际影响了该控制信息具体映射的时频资源。
如果发送设备选择候选2为接收设备发送控制信息,如图5所示,第一时频资源可以承载控制信息,实际没有承载;如图5所示,第一时频资源不可以承载控制信息,实际也没有承载。但是,第一时频资源是否可以承载控制信息导致了候选1包含或者不包含第一时频资源,相应地,第一时频资源是否可以承载控制信息导致了候选2对应的时频资源位置发生了变化。即,当发送设备选择候选2为接收设备发送控制信息时,无论第一时频资源是否与控制信息对应的搜索空间重叠,实际承载控制信息的时频资源都发生了变化。
因此,作为一种可能的实现方式,本申请实施例提供的方法,在发送设备发送控制信息之前,如图8所示,还包括:
S106、发送设备根据第一控制信息类型确定控制信息的时频资源。
具体地,发送设备可以根据控制信息类型,确定第一时频资源可以承载控制信息或者不可以承载控制信息。对于发送设备具体如何确定控制信息的类型,将在下述实施例中详细介绍。
具体的,发送设备确定控制信息为第一控制信息类型,控制信息对应的资源集合与第一时频资源重叠,第一控制信息类型用于指示第一时频资源可承载控制信息;或,发送设备确定控制信息为第二控制信息类型,第二控制信息类型用于指示第一时频资源不可以承载控制信息;发送设备确定控制信息为第一控制信息类型,第一控制信息类型用于指示控制信息对应的搜索空间与第一时频资源重叠;或,第一控制信息类型用于指示控制信息对应的搜索空间与第一时频资源不重叠。
然后,发送设备可以根据第一时频资源是否可以承载控制信息,确定控制信息对应的搜索空间(或者候选,或者候选对应的CCE)对应的时频位置,即确定控制信息的时频资源。可选的,发送设备可以确定当时发送的控制信息对应聚合等级,再根据聚合等级确定控制信息对应的搜索空间或者控制信息对应的候选等。
可选地,发送设备在控制信息对应的候选中选择用于承载控制信息的候选,即确定控制信息的时频资源。
本申请提供的方法,在步骤S103之前,还包括:
S107、接收设备确定控制信息为第一控制信息类型,则确定控制信息对应的搜索空间包括的时频资源。
以及,接收设备接收控制信息之前或者接收设备接收控制信息时,还包括:
S108、接收设备确定控制信息为第一控制信息类型且资源集合与第一时频资源重叠,接收设备确定第一时频资源可用于承载控制信息或者不可以承载控制信息。
具体地,接收设备可以根据待检测或者待检测的控制信息确定控制信息类型从而确定第一时频资源可以承载控制信息或者不可以承载控制信息,或者,确定第一时频资源是否和控制信息对应的搜索空间(或者,对应的候选,或者对应的CCE)重叠。控制信息为第一控制信息类型,控制信息对应的资源集合与第一时频资源重叠,第一控制信息类型用于指示第一时频资源可承载控制信息;或,第一控制信息类型用于指示第一时频资源不可以承载控制信息;控制信息为第一控制信息类型,第一控制信息类型用于指示控制信息对应的搜索空间与第一时频资源重叠;或,第一控制信息类型用于指示控制信息对应的搜索空间与第一时频资源不重叠。
然后,接收设备可以根据第一时频资源是否可以承载控制信息,确定控制信息对应的搜索空间(或者候选,或者候选对应的CCE)对应的时频位置。进一步地,接收设备可以确定不同聚合等级对应的搜索空间或者控制信息对应的候选等。
确定不同聚合等级对应的搜索空间或者控制信息对应的候选等之后,接收设备可以不同聚合等级(或者一个聚合等级)的候选上检测控制信息,以确定是否发送了控制信息和控制信息的内容,实施控制信息接收。
需要注意的是,本申请实施例中的S108可以在S103之前实施,例如,接收设备将控制信息对应的所有聚合等级的候选确定完毕后,然后在确定好的候选上实施检测和接收控制信息。S108也可以在S103实施的过程中实施,例如,接收设备确定一个聚合等级的候选,在该聚合等级的候选上实施检测和接收控制信息,而后,如果必要, 再确定下一个聚合等级的候选,在该聚合等级的候选上实施检测和接收控制信息。这里,“如果必要”可以为在前一个聚合等级对应的候选上没有检测到控制信息,或者,在前一个聚合等级对应的候选上检测到控制信息,但是还需要尝试其它聚合等级以减小检测到的控制信息为虚警的概率,等等。如何具体实施控制信息的接收不同设备生产厂商可以由不同的实现方法,本申请实施例不以此为限。
接下来对控制信息类型进行阐述。具体的,第一控制信息类型基于以下至少一个因素确定,包括:控制信息的格式、控制信息的时频资源位置、或控制信息对应的监测周期类型。
不同格式的控制信息可以用于不同场景,例如调度普通优先级数据和高优先级数据的控制信息格式可以不相同。控制信息类型可以为控制信息格式,或者说,控制信息类型可以由控制信息格式确定。以调度普通数据的控制信息为格式1,调度高优先级数据的控制信息为格式2为例进行说明。一个例子中,第一控制信息类型为格式2,第一控制信息类型用于指示第一时频资源可以承载控制信息,或者,第一控制信息类型用于指示控制信息对应的搜索空间与第一时频资源重叠。发送设备在实施S107的时候,即确定控制信息的时频资源的时候,如果发送设备确定待发送的是格式2的控制信息,就可以确定第一时频资源可以承载控制信息,并可以“第一时频资源可以承载控制信息”为前提确定控制信息的时频资源。如果发送设备确定待发送的是格式1的控制信息,就可以确定第一时频资源不可以承载控制信息,并可以“第一时频资源不可以承载控制信息”为前提确定控制信息的时频资源。接收设备在实施S103的时候,即确定第一时频资源上是否可承载控制信息的时候,如果接收设备确定此次接收的目标控制信息为格式2的控制信息,就可以确定第一时频资源可以承载控制信息,并可以“第一时频资源可以承载控制信息”为前提确定控制信息的对应的搜索空间,或者,对应的候选,或者对应的CCE的时频资源位置。如果接收设备确定此次接收的目标控制信息为格式1的控制信息,就可以确定第一时频资源不可以承载控制信息,并可以“第一时频资源不可以承载控制信息”为前提确定控制信息的搜索空间等。
另一个例子中,第一控制信息类型为格式1,第一控制信息类型用于指示第一时频资源不可以承载控制信息,或者,第一控制信息类型用于指示控制信息对应的搜索空间与第一时频资源不重叠。实施过程类似上一个例子,这里不再赘述。
需要说明的是,上述以普通数据和高优先级数据的控制信息为例进行说明,但本申请实施例不以此为限。任何用不同控制信息格式区分第一时频资源是否可以承载控制信息的实施方法均在本申请实施例保护范围之内。此外,上述以格式1和格式2为例,具体实施中,可以由一类格式和另一类格式代替。一类格式或者另一类可以一种格式,也可以包含大于一种格式。
以控制信息格式区分第一时频资源是否可以承载控制信息有助于以比较简单的逻辑实现发送设备和接收设备的程序,但是,代价可能是控制信息格式的种类偏多,需要发送设备和接收设备以更多的存储器实现程序。
由于高优先级数据通常对传输时延和可靠性的要求较高,因此高优先级数据通常需要更多的传输机会。例如,URLLC数据可能会要求1ms内传输可靠性达到99.999%,因此,这样的URLLC数据可能会需要系统在1ms内支持7到8个传输机会,相应地, 用于调度这种URLLC数据的控制信息可能出现在1ms的多个位置。而,普通数据没有类似的高传输要求,1ms只有1个传输机会即可满足普通数据的需求。相应地,减少传输机会有助于系统以更低的开销支持普通数据传输,也有助于接收普通数据的接收设备节省更多的能耗,因此,普通数据的控制信息通常出现在1ms的开头。
相应地,控制信息类型可以为控制信息的时频资源位置,或者说,控制信息类型可以由控制信息的时频资源位置确定。以调度普通数据的控制信息的时频资源为时频资源1,调度高优先级数据的控制信息的时频资源为时频资源2为例,进行说明。时频资源1位于第A类时频资源中,第A类时频资源位于每个时隙的最前面2-3个符号。时频资源2位于第B类时频资源中,第B类时频资源位于每个时隙的除最前面2-3个符号。一个例子中,第一控制信息类型为属于第B类时频资源的控制信息,第一控制信息类型用于指示第一时频资源可以承载控制信息,或者,第一控制信息类型用于指示控制信息对应的搜索空间与第一时频资源重叠。发送设备在实施S10X的时候,即确定控制信息的时频资源的时候,如果发送设备确定待发送的控制信息需要在第B类时频资源中传输,就可以确定第一时频资源可以承载控制信息,并可以“第一时频资源可以承载控制信息”为前提确定控制信息的时频资源。如果发送设备确定待发送的控制信息需要在第A类时频资源中传输,就可以确定第一时频资源不可以承载控制信息,并可以“第一时频资源不可以承载控制信息”为前提确定控制信息的时频资源。接收设备在实施S103的时候,即确定第一时频资源上是否可承载控制信息的时候,如果接收设备确定此次接收的目标控制信息需要在第B类时频资源上监测,就可以确定第一时频资源可以承载控制信息,并可以“第一时频资源可以承载控制信息”为前提确定控制信息的对应的搜索空间,或者,对应的候选,或者对应的CCE的时频资源位置。如果接收设备确定此次接收的目标控制信息需要在第A类时频资源上监测,就可以确定第一时频资源不可以承载控制信息,并可以“第一时频资源不可以承载控制信息”为前提确定控制信息的搜索空间等。
另一个例子中,第一控制信息类型为属于第A类时频资源的控制信息,第一控制信息类型用于指示第一时频资源不可以承载控制信息,或者,第一控制信息类型用于指示控制信息对应的搜索空间与第一时频资源不重叠。实施过程类似上一个例子,这里不再赘述。
第B类时频资源与第A类时频资源可以对应相同或者不同的频域资源。例如,普通数据和高优先级数据可以在一个载波或者子带或者BWP(Bandwidth part)上调度或者传输,第B类时频资源与第A类时频资源可以对应相同的频域资源。又例如,普通数据和高优先级数据分别在两类载波或者子带或者BWP(Bandwidth part)上调度或者传输,第B类时频资源与第A类时频资源可以对应不同的频域资源。其中,两类载波等中的一类仅能够承载普通数据,或者,仅能够承载高优先级数据。
需要说明的是,上述以普通数据和高优先级数据的控制信息为例进行说明,但本申请不以此为限。任何用不同控制信息的时频资源位置区分第一时频资源是否可以承载控制信息的实施方法均在本申请保护范围。此外,更为具体地,控制信息的时频资源位置,可以是具体承载控制信息的时频资源位置,也可以是控制信息对应的资源集合的时频资源位置。
以控制信息的时频资源位置区分第一时频资源是否可以承载控制信息有助于以更简单的方式实现发送设备和接收设备的程序,但是,代价可能是控制信息区分的情况较多,逻辑上略微复杂。
控制信息类型还可以为控制信息对应的监测周期类型,或者说,控制信息类型可以由控制信息对应的监测周期确定。更为具体地,该监测周期可以是搜索空间对应的周期,也可以是资源集合对应的周期。仍然以普通数据和高优先级数据为例,普通数据的控制信息对应的监测周期大于高优先级数据对应的监测周期。监测周期可以由发送设备通过RRC信令为接收设备进行配置。普通数据对应的周期可以以时隙为单位进行配置,例如,最短为1个时隙等。高优先级数据对应的周期可以以符号为单位进行配置,例如,最短为1个符号等。发送设备和接收设备均可以根据控制信息对应监测周期是以时隙为单位进行配置的还是以符号为单位进行配置的,确定第一时频资源可以承载控制信息,或者,确定第一时频资源不可以承载控制信息。具体实施方法可以参照上面对“控制信息格式”和“控制信息的时频资源位置”的描述,这里不再赘述。
需要说明的是,上述以普通数据和高优先级数据的控制信息为例进行说明,但本申请不以此为限。任何用不同控制信息对应的监测周期区分第一时频资源是否可以承载控制信息的实施方法均在本申请保护范围。
以控制信息对应的监测周期区分第一时频资源是否可以承载控制信息有助于以简化发送设备和接收设备的程序,但是,代价可能是牺牲了一些调度可能性。
上述三种确定控制信息类型的方法可以结合使用,例如,调度普通数据和高优先级数据的控制信息彼此控制信息格式不同且对应的监测周期也不同。如此可以获得更为鲁棒的实现方式,避免因为一种方式的错误理解或者漏检测导致的接收错误。
本申请实施例提供的上述三种实现控制信息类型的方法,单独使用或者结合使用可以在实现复杂度、实现逻辑、实现寄存器等多个方面为发送设备提供更多的选择和调度灵活性,在平衡了各种需求和代价之后,发送设备可以选择合适的方法实施。
可以理解的是,在发送设备向接收设备发送控制信息之前,接收设备和发送设备之间约定或者默认,控制信息的类型与第一时频资源是否承载数据/是否可承载控制信息/是否和控制信息对应的搜索空间重叠之间的关联关系,这样接收设备便可以根据所接收的控制信息的类型从预先约定的关联关系中确定第一时频资源上是否承载数据或者控制信息。
由于在实际过程中,发送设备在向接收设备发送控制信息的过程中还可以利用控制信息向接收设备所指示某一时频资源上是否承载数据,这样接收设备在接收到控制信息之后,便可以根据控制信息的指示在第一时频资源上获取数据,因此,本申请在S101中,控制信息还用于指示接收设备在第二时频资源上接收数据,第二时频资源与第一时频资源重叠,控制信息还用于指示第一时频资源承载数据;或,控制信息还用于指示第一时频资源不承载数据控制信息。接下来阐述,控制信息如何指示第一时频资源承载数据,或者,控制信息如何指示第一时频资源不承载数据。因此,作为一种可能的实现方式,本申请实施例提供的方法,还包括:
S109、接收设备根据控制信息确定第一时频资源上是否可承载数据。
由于在实际过程中,发送设备和接收设备之间可以约定或者默认多种实现方式来 指示第一时频资源上是否承载数据,但是发送设备和接收设备所约定或者默认的指示控制信息是否承载数据的方式不同,接收设备根据控制信息确定第一时频资源上是否可承载数据的方式也会存在差异,因此,本申请现结合不同情况下控制信息的内容详细的介绍,本申请步骤S109的具体实现方式:
作为一种可能的实现方式,控制信息还用于指示第一时频资源是否承载数据,具体可以通过以下方式实现:控制信息包括第一指示信息,该第一指示信息用于指示第一时频资源承载数据,或者控制信息包括第二指示信息,该第二指示信息用于指示第一时频资源为未承载有数据。相应的,本申请中的步骤S108还可以通过以下方式实现:
S1091、接收设备根据控制信息中包括的第一指示信息,确定第一时频资源承载有数据,其中,第一指示信息用于指示第一时频资源承载有数据。或者,接收设备根据控制信息中包括的第二指示信息,确定第一时频资源未承载有数据,其中,第二指示信息用于指示第一时频资源承载有数据。
示例性的,该第一指示信息可以为第一指示符,该第一指示符用于指示第一时频资源承载有数据,例如,该第一指示符可以为“1”,本申请对此不进行限定,该第二指示信息可以为第二指示符,该第二指示符用于指示第一时频资源未承载有数据,例如,该第二指示符可以为“0”。
该第一指示信息或第二指示信息可以由控制信息中的一个专用字段承载,即该专用字段仅用于指示第一时频资源是否承载数据。该指示信息也可以由控制信息中用作其它用途的字段中的一个比特或者多个比特承载,该一个或多个比特用于指示第一时频资源是否承载数据。
发送设备利用控制信息中包括的第一指示信息或第二指示信息,向接收设备指示第一时频资源是否承载数据,有助于简单化程序实现的逻辑,并减少由于误检造成的接收错误。
作为另一种可能的实现方式,控制信息还用于指示第一时频资源承载数据,包括:控制信息隐式指示第一时频资源承载有数据或者未承载有数据。相应的,本申请中的步骤S109还可以通过以下方式实现:
S1092、接收设备根据控制信息的隐式指示,确定第一时频资源承载有数据。或者接收设备根据控制信息的隐式指示,确定第一时频资源未承载有数据。
示例性的,发送设备可以对该控制信息利用扰码序列加扰,以通过加扰的方式用控制信息来指示第一时频资源是否承载数据。
另一示例性的,发送设备和接收设备之间事先约定或者默认,利用控制信息在一个时隙中的位置来隐式指示第一时频资源是否承载数据,例如,利用控制信息在一个时隙的开始位置(最前面2-3个符号)来隐式指示第一时频资源未承载数据,利用控制信息在一个时隙的中间或者后面位置(非最前面2-3个符号)来隐式指示第一时频资源承载数据。
作为又一种可能的隐式实现方式,控制信息还用于隐式指示第一时频资源承载数据,可以通过以下方式实现:控制信息通过基于第一时域单位指示第二时频资源向接收设备指示第一时频资源承载数据,或者控制信息通过基于第一时域单位指示第二时频资源向接收设备指示第一时频资源未承载数据。相应的,本申请中的步骤S108具体 还可以通过以下方式实现:
S1093、接收设备确定第二时频资源基于第一时域单位指示,确定第一时频资源承载有数据,或者接收设备确定第二时频资源基于第一时域单位指示,确定第一时频资源未承载有数据。
示例性的,当控制信息以符号为单位向接收设备指示第二时频资源在时域上持续的时间长短的时候,该控制信息指示接收设备第一时频资源上承载数据;当控制信息至少以时隙为单位向接收设备指示第二时频资源在时域上持续的时间长短的时候,该控制信息指示接收设备第一时频资源未承载数据。
或者说,控制信息以基于非时隙(non-slot-based)的方法指示接收设备在第二时频资源接收数据,第二时频资源与第一时频资源重叠,控制信息还用于指示第一时频资源承载数据。控制信息以基于时隙(slot-based)的方法指示接收设备在第二时频资源接收数据,第二时频资源与第一时频资源重叠,控制信息还用于指示第一时频资源未承载数据。
相较于前两种隐式的指示方法,这种隐式方法没有额外的标准化开销(因为slot-based/non-slot-based调度方法已经被5G NR系统接受)。但是,可能会一定程度的僵化调度的优先级机制,限制了发送设备调度的灵活性。
发送设备和接收设备之间利用控制信息的隐式指示方式来指示第一时频资源上是否承载数据,可以避免在控制信息中额外的增加指示信息,从而减少了信令开销。
作为再一种可能的实现方式,控制信息还用于指示第一时频资源承载数据,可以通过以下方式实现:控制信息指示数据为第一数据类型,第一数据类型用于指示第一时频资源承载数据,或者控制信息指示数据为第二数据类型,第二数据类型用于指示第一时频资源未承载有数据。相应的,本申请中的步骤S109还可以通过以下方式实现:
S1094、接收设备确定控制信息所指示数据的类型为第一数据类型,则接收设备确定第一时频资源承载有数据,其中,第一数据类型用于指示第一时频资源承载数据。或者,接收设备确定控制信息所指示数据的类型为第二数据类型,则接收设备确定第一时频资源未承载有数据,其中,第二数据类型用于指示第一时频资源未承载数据。
可以理解的是,在实际过程中,接收设备中至少具有第一数据类型与第一时频资源承载有数据之间的关联关系以及具有第二数据类型与第一时频资源未承载有数据之间的关联关系,该关联关系可以由发送设备配置给接收设备,也可以由接收设备从其他设备处获取,本申请对此不进行限定。
具体的,发送设备利用控制信息指示数据为第一数据类型或者第二数据类型,可以通过以下方式实现:发送设备利用控制信息指示数据的目标传输可靠性,数据的目标传输时延,数据的业务类型中的至少一项。可以理解的是,接收设备中至少具有每个数据各自对应的目标传输可靠性,数据的目标传输时延,数据的业务类型中的至少一项与第一数据类型之间的对应关系,这样接收设备在接收到控制信息时,便可以根据对应关系确定控制信息指示数据的类型为第一数据类型,从而再根据上述关联关系确定第一时频资源承载有数据。
另一方面,本申请中接收设备还可以根据控制信息所指示的在第一时频资源上接收的数据的类型,确定第一资源粒子上是否承载有数据,因此,作为另一种可能的实 现方式,本申请中的步骤109可以通过以下方式实现:
S1095、接收设备确定数据为第一数据类型,确定第一时频资源承载有数据,或者接收设备确定数据为第二数据类型,则确定第一时频资源未承载有数据。
具体的,第一数据类型和第二数据类型可以基于以下至少一个因素确定:数据的目标传输可靠性、数据的目标传输时延、或数据的业务类型。其中,第一数据类型和第二数据类型满足以下至少一个条件:
第一数据类型的目标传输可靠性和第二数据类型的目标传输可靠性不同,第一数据类型的目标传输时延和第二数据类型的目标传输时延不同,第一数据类型中业务类型和第二数据类型的业务类型不同。
这是由于在实际传输过程中,有的数据的目标传输时延小,例如,URLLC数据,而有的数据的目标传输时延相较于URLLC数据较大,例如,eMBB数据,通过控制信息以数据的目标传输时延来指示数据类型,这样接收设备便可以根据数据的目标传输时延确定已被配置的第一时频资源是否承载该数据。因此,发送设备和接收设备之间可以根据数据的目标传输时延确定数据类型,或者说,数据类型是以目标传输时延划分的。
类似地,有的数据的目标传输可靠性要求较高,例如,URLLC数据,而有的数据的目标传输可靠性要求较低,例如eMBB数据。发送设备和接收设备之间可以根据数据的目标传输可靠性确定数据类型,或者说,数据类型是以目标传输可靠性划分的。
更为具体地,发送设备和接收设备之间还可以根据数据的目标传输可靠性,和数据的目标传输时延两个特征或者还包括其它特征来指示第一时频资源是否承载数据,这样接收设备在接收到控制信息用于指示某一特征相同,但是另一特征不同的两个或两个以上的数据的时候,还可以通过另一不同的特征来区分第一时频资源上是否承载数据。
进一步地,发送设备和接收设备之间可以根据数据的业务类型确定数据类型,或者说,数据类型是数据的业务类型。一个数据业务类型对应着该业务数据传输的要求。可以包括但不限于传输可靠性、传输时延、传输数据速率等。
除所述控制信息指示以外,所述数据类型还可以根据承载数据的载波或者子带或者BWP确定。
具体的,接收设备可以根据控制信息所具有的特征来判断控制信息所属的类型,示例性的,接收设备可以根据控制信息的格式、承载控制信息的时频资源位置以及控制信息对应的检测周期来确定控制信息的类型。
具体的,承载控制信息的时频资源位置是指调度数据DCI位于一个时隙的什么位置,例如位于一个时隙开头的几个符号内对应于一种传输,而位于一个时隙的其它位置的时候对应于另一种传输。开始的几个符号可以是1个、2个或者3个等。
此外,接收设备还可以根据控制信息的传输调度模式,传输调度单位,目标错误概率,混合自动重传请求(hybrid automatic repeat request,HARQ)反馈机制,信道状态信息(channel state information,CS I)反馈机制来确定控制信息的类型。
具体的,不同类型的控制信息的传输调度模式包含以下因素中的至少一种:多入多出技术(multiple-input multiple-output,MIMO)传输方式,可以是传输分集、空间 复用、Large CDD、采用预编码矩阵、不同波束类型等;天线数;单次传输或者重复传输。例如,第一类型控制信息的传输调度模式包括MIMO传输方式,第二类型控制信息的传输调度模式包括单次传输,这样接收设备在接收到控制信息后,便可以根据所接收到的控制信息的传输调度模式确定该控制信息所属的类型,从而确定第一时频资源的第一资源粒子上是否承载数据。
不同类型的控制信息的传输调度单位可以通过以下方式区别:即控制信息传输使用中时域单位在时域持续时间,例如,一种传输以时隙为调度单位,一次传输调度一个或者一个以上时隙进行传输。还可以是以复位为调度单位,一次传输调度一个或者一个以上符号进行传输。
示例性的,第一类型控制信息的目标错误概率较高,如10%,或者第二类型控制信息的目标错误概率较低,如0.1%,或者传输的错误概率极低,如0.01%,这样接收设备在接收到控制信息时,即可以通过所接收到的控制信息的目标错误概率来区分所接收到的控制信息的类型。
不同类型的控制信息的HARQ反馈机制不同,例如,第一类型控制信息需要反馈A/N,或者,第二类型控制信息不需要反馈A/N;又例如,第一类型控制信息需要在接收信号结束后的m个时间单位反馈A/N,或者,第二类型控制信息需要在接收信号结束后的n个时间单位反馈A/N(n小于m)。
不同类型的控制信息的CSI反馈机制不同,例如,第一类型控制信息不需要反馈即时CSI信息,第二类型控制信息传输需要反馈即时CSI信息用于基站准确调度。需要说明的是,传输需要反馈即时CSI信息可以是,一旦该传输被调度了,接收设备即会向发送设备反馈与该次传输相关的即时CSI信息,还可以是,一旦伴随该次传输发送设备指示接收设备反馈与该次传输相关的即时CSI信息等。“与该次传输相关”是指,即时CSI信息对应的时频资源与该次传输数据和/或导频所占的时频资源至少包含一个相同的资源粒子。
虽然,上述简单地以URLLC数据和eMBB数据为例进行区分(示例性的,eMBB业务数据有:超高清视频等,这些业务的主要特点是传输数据量大、传输速率很高。URLLC业务数据有:工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用,这些业务的主要特点是要求超高可靠性、低延时,传输数据量较少以及具有突发性。典型的mMTC业务数据有:智能电网配电自动化、智慧城市等,主要特点是联网设备数量巨大、传输数据量较小、数据对传输时延不敏感,这些mMTC终端需要满足低成本和非常长的待机时间的需求。此外,数据还可以是非业务数据,例如,可以是发送设备与接收设备之间交互的信令,或者发送设备向接收设备发送的广播信息等),但实际上,5G系统的目标是支持各种传输要求不同的业务。也即,URLLC这种高可靠性可能是5G系统对低时延高可靠传输支持的极限。在极限范围里,5G系统可以定义不同的传输时延要求,和/或,不同的传输可靠性要求。因此,在上述实施方案的基础上,系统还可以定义一个或者多个传输时延的水平,当两个数据或者两个信号冲突时,发送设备和终端设备可以根据两个数据或者两个信号的传输时延水平的比较,确定第一时频资源上承载哪个数据或信号。类似地,也可以定义传输可靠性的水命。此外,根据业务类型确定数据类型, 可以综合比较两种业务类型数据对传输时延的要求,提供更为全面的比较机制。
基于目前的5G系统提供的先进的传输性能,由5G系统承载的业务可能会远多于今天做能预见的。本申请实施例提供的上述三种根据数据类型确定第一时频资源上是否承载数据的方法,单独使用或者结合可以为发送设备和接收设备提供更多的选择和调度灵活性,在平衡了各种需求和代价之后,发送设备可以选择合适的方法实施。
作为再一种可能的实现方式,控制信息还用于指示第一时频资源承载数据,具体可以通过以下方式实现:控制信息为第一控制信息类型,第一控制信息类型用于指示第一时频资源承载数据,或者,第一控制信息类型用于指示第一时频资源不承载数据。
S1096、接收设备确定控制信息为第一控制信息类型,确定第一时频资源承载有数据;接收设备确定控制信息为第二控制信息类型,确定第一时频资源未承载有数据。
具体的,控制类型基于以下至少一个因素确定:控制信息的格式、控制信息的时频资源位置、或控制信息对应的监测周期类型。其中第一控制信息类型和第二控制信息类型满足以下至少一个条件,第一控制信息类型的格式和第二控制信息类型的格式不同,第一控制信息类型对应的监测周期类型和第二控制信息类型对应的监测周期类型不同,第一控制信息类型的时频资源位置和第二控制信息类型的时频资源位置不同。
以调度普通数据的控制信息为格式1,调度高优先级数据的控制信息为格式2为例,进行说明。第一时频资源不承载普通数据,第一时频资源承载高优先级数据。第一时频资源与第二时频资源重叠。一个例子中,第一控制信息类型为格式2,第一控制信息类型用于指示第一时频资源可以承载数据。发送设备在确定承载数据的时频资源的时候,如果发送设备确定调度该数据的控制信息是格式2的控制信息,就可以确定第一时频资源可以承载数据,并可以“第一时频资源可以承载数据”为前提确定承载数据的时频资源。如果发送设备确定调度该数据的控制信息是格式1的控制信息,就可以确定第一时频资源不可以承载数据,并可以“第一时频资源不可以承载数据”为前提确定承载数据的时频资源。接收设备在确定第一时频资源上是否可承载数据的时候,如果接收设备确定指示在第二时频资源上接收数据的控制信息为格式2,就可以确定第一时频资源可以承载控数据,并可以“第一时频资源承载数据”为前提确定承载数据的时频资源位置。如果接收设备确定指示在第二时频资源上接收数据的控制信息为格式1,就可以确定第一时频资源可以不承载控数据,并可以“第一时频资源不承载数据”为前提确定承载数据的时频资源位置。
另一个例子中,第一控制信息类型为格式1,第一控制信息类型用于指示第一时频资源不承载数据。实施过程类似上一个例子,这里不再赘述。
需要说明的是,上述以普通数据和高优先级数据的控制信息为例进行说明,但本申请实施例不以此为限。任何用不同控制信息格式区分第一时频资源是否承载数据的实施方法均在本申请保护范围。此外,上述以格式1和格式2为例,具体实施中,可以由一类格式和另一类格式代替。一类格式或者另一类可以一种格式,也可以包含大于一种格式。
控制信息类型基于控制信息的时频资源位置或者控制信息对应的监测周期类型确定例子与根据二者确定第一时频资源是否可以承载控制信息的例子类似,有益效果也类似,这里不再赘述。
上述方案中,本申请提供了多种“控制信息指示第一时频资源承载数据,或者第一时频资源不承载数据的方法。单独使用或者结合可以为发送设备和接收设备提供更多的选择和调度灵活性,在平衡了各种需求和代价之后,发送设备可以选择合适的方法实施。
可选的,本申请中的控制信息还用于指示第一时频资源不承载数据和控制信息中至少一项。
具体的,控制信息指示第一时频资源不承载数据和控制信息中任一项可以理解为:控制信息指示第一时频资源上既不承载数据,又不承载控制信息,这样接收设备在接收到控制信息时便可以确定第一时频资源为避让时频资源,便不会在第一时频资源上寻找数据和控制信息。
可选的,在控制信息还用于指示第一时频资源不承载数据和控制信息中至少一项时,第一时频资源承载零功率信号;或者,第一时频资源承载发送给接收设备的参考信号。
可选的,参考信号为信道状态信息参考信号(Channel State Information-Reference Signal,CSIRS)。
具体的,信道状态信息参考信号仅用于信道状态信息的取得CSI acquisition。
可选的,如图9所示,本申请实施例提供的方法还包括:
S110、发送设备在第二时频资源上向接收设备发送数据。
发送设备确定了第一时频资源是否承载数据,确定承载数据的时频资源位置,将数据映射到用于承载数据的时频资源后,生成发送信号,在第二时频资源上向接收设备发送数据。
S111、接收设备在第二时频资源接收数据。
需要说明的是,S109可以S110之后实施,即接收设备可以将第二时频资源上的信号接收下来,确定第一时频资源是否承载数据,在确定第二时频资源上用于承载数据的时频资源,并对该接收信号进行处理。S109也可以在S110实施的过程中实施,例如,接收设备部分接收了第二时频资源上的信号,即确定第一时频资源是否承载数据,在确定第二时频资源上用于承载数据的时频资源,并对已接收的信号进行处理。类似地,S109也可以在S110之前实施。如何具体实施数据的接收不同设备生产厂商可以由不同的实现方法,本申请不以此为限。
可选的,本申请提供的控制信息还用于指示接收设备在第三时频资源上发送上行数据。相应的,本申请提供的方法还包括:
S112、接收设备在第三时频资源上向发送设备发送上行数据。
