具体实施方式
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清楚地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本申请保护的范围。
本申请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,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,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,字符 “/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例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,还可用于其他无线通信系统,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。本申请实施例中的术语“系统”和“网络”常被可互换地使用,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。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,但是这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的结果示意图。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:智能手表、手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,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、发送接收点(Transmitting Receiving Point,TRP)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,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示,为本申请一示例性实施例提供的监听PDCCH的方法200的流程示意图,该方法200可以但不限于由终端执行,具体可由安装于终端中的硬件和/或软件执行。本实施例中,所述方法200至少可以包括如下步骤。
S210,终端根据第一时间单元上的第一信息,确定用于PDCCH监听的目标监听资源。
其中,所述第一时间单元用于PDCCH监听的时间单元,如符号(Symbol)、时隙(Slot)、子时隙(sub-slot)子帧(sub-frame)等。本实施例中,所述第一时间单元可以通过协议约定或高层信令配置等,在此不做限制。
所述第一信息包括子带(subband)的配置信息和/或保护带(guardband)的配置信息。可以理解,在网络全双工或者灵活双工的情况下,为了避免上下行之间的干扰,会在上行和下行的频域资源之间引入保护带,以避免上下行之间的干扰。例如,对于成对频谱之间的保护带,是上行载波和下行载波之间的保护间隔。又例如对于非成对频谱,在相同的时间单元内,不同的子带的传输方向不同,在子带内也需要引入保护间隔,即引入载波内的子带之间的保护带。
本实施例中,为了实现目标监听资源的确定,所述子带的配置信息可以包括子带的方向信息和/或大小信息,例如,所述子带的方向信息可以是 上行、下行或灵活,也就是,所述子带可以是上行子带、下行子带或灵活配置的子带。一种实现方式中,所述子带可以包括连续的多个资源块(Resource Block,RB)或资源单元(Resource element,RE),也可以用RB集(set)或RE set描述。
所述保护带的配置信息可以包括保护带的位置信息和/或大小信息。可以理解,所述保护带表示终端不进行信号发送或者接收的频域资源,该保护带可以通过RB数或RE数、RB位置或RE位置的方式进行描述。
需要注意,在不同的时间单元上,子带的方向信息或大小信息可能不同,所述保护带的大小信息或位置信息也可能不同。例如,在某个时间单元上全上行子带或者全下行子带的子带配置,无需保护带。又例如,在某个时间单元,可存在上行子带、下行子带、灵活子带的混合配置,且需要在子带间配置一个或者多个保护带。
一种实现方式中,前述的子带的方向信息可以通过高层信令、媒体访问控制控制单元(Medium Access Control-Control Element,MAC-CE)、下行控制信令(Downlink Control Information,DCI)等进行指示。
进一步,所述终端基于第一信息确定的所述目标监听资源可以包括CORESET、搜索空间(Search Space,SS)、SS set中的至少一项对应的资源。
可以理解,网络侧可以为终端配置多个CORESET,每个CORESET中可以包括连续的符号数、频域资源、预编码颗粒度、交织方式、解调参考信号(Demodulation Reference Signal,DMRS)映射方式等,每个CORESET中又可以配置多个SS,终端在多SS中监听PDCCH。所述SS的配置可以包括用于PDCCH监听的聚合等级、周期和偏移值(用于确定监听时机(monitor occasion))等。
S220,基于所述目标监听资源,监听所述PDCCH。
其中,终端在基于目标监听资源(如CORESET、SS、SS set),监听 所述PDCCH的实现过程,在此不做限制。
在本实施例中,终端根据第一时间单元上的子带的配置信息和/或保护带的配置信息,确定用于PDCCH监听的目标监听资源,由此,能够使得终端基于可用的目标监听资源监听PDCCH,避免了由于PDCCH对应的监听资源与除该监听资源以外的其他资源重叠,而导致的无法有效监听PDCCH的问题,确保了无线通信性能。
如图3a所示,为本申请一示例性实施例提供的监听PDCCH的方法300的流程示意图,该方法300可以但不限于由终端执行,具体可由安装于终端中的硬件和/或软件执行。本实施例中,所述方法300至少可以包括如下步骤。
S310,终端根据第一时间单元上的第一信息,确定用于PDCCH监听的目标监听资源。
其中,所述第一信息包括子带的配置信息和/或保护带的配置信息。
可以理解,S310的实现过程除了可参照前述方法实施例200的描述之外,作为一种可能的实现方式中,所述目标监听资源可以满足以下(1)和/或(2)。
(1)所述目标监听资源不与第一子带重叠(Overlapping),所述第一子带包括上行子带和/或灵活配置的子带。换言之,所述目标监听资源(如CORESET、SS set(s)、SS)对应的频域资源不与上行或灵活的第一子带重叠。
例如,在所述目标监听资源为CORESET的情况下,如果一个CORESET的部分频域资源和上行或灵活的第一子带重叠,但是和该CORESET关联的SS set中的一个SS#x的频域资源不与上行或灵活的第一子带重叠,所述终端可以监听该SS#x上的PDCCH,其中,#x表示SS的索引。
一种实现方式中,网络侧只能在下行或灵活的子带上配置CORESET。
(2)所述目标监听资源不与第一保护带重叠。换言之,所述目标监听资源(如CORESET、SS set(s)、SS)对应的频域资源不与第一保护带重叠。
本实施例中,前述(1)和(2)中所述的第一子带和/或所述第一保护带可以由网络侧配置,以用于目标监听资源的确定。
需要注意的,如果所述终端根据SS的配置,确定在所述第一时间单元进行PDCCH的监听,那么,该SS可关联到CORESET。也就是,在所述目标监听参数包括所述CORESET和SS的情况下,所述SS与CORESET关联。
S320,基于所述目标监听资源,监听所述PDCCH。
可以理解,S320的实现过程除了可参照方法实施例200中的相关描述之外,作为一种可能的实现方式,S320的实现过程还可以包括图3a中所示的S321和S322,内容如下。
S321,在所述目标监听资源包括CORESET、所述终端支持在N个CORESET上监听所述PDCCH、但所述目标监听资源中包括M个CORESET情况下,从所述M个所述CORESET中选取N个所述CORESET,其中,N<M。
本实施例中,所述终端从M个所述CORESET中选取N个所述CORESET的过程可以包括以下(1)-(4)中的至少之一。
(1)基于每个所述CORESET的索引值,从M个所述CORESET中选取具有第一索引值的N个CORESET。
其中,所述第一索引值可以为多个索引值中的N个最大索引值或N个最小索引值等。
例如,假设N为2,M为4,M个索引值分别为a、b、c、d,a<b<c<d,那么,N个最大索引值可为c和d,也就是,从M个CORESET中选取的 N个CORESET分别为索引值为c和d的CORESET;相应的,N个最小索引值可以为a和b,也就是,从M个CORESET中选取的N个CORESET分别为索引值为a和b的CORESET。
(2)基于每个所述CORESET中包括的资源数,从M个所述CORESET中选取资源数最多的N个CORESET,所述资源数包括RB数和/或符号数。
其中,假设M为4,N为2,且4个CORESET中资源数分别为a、b、c、d,a<b<c<d,那么,从M个所述CORESET中选取的N个CORESET分别是包括有c个资源数以及d个资源数的CORESET。
(3)基于与每个所述CORESET关联的SS的索引值,从M个所述CORESET中选取具有第二索引值的SS所关联的N个CORESET。
其中,与前述的第一索引值类似,所述第二索引值可以为多个索引值中的N个最大索引值或N个最小索引值,相应的,根据与所述CORESET关联的SS的索引值选取N个CORESET的过程与前述(1)中的选取过程类似,在此不再赘述。
(4)基于每个所述CORESET的搜索空间类型,从M个所述CORESET中选取N个CORESET,其中,配置了公共搜索空间(Common Search Space,CSS)配置的CORESET,相对于配置了UE特定搜索空间(UE-specific search space,USS)配置的CORESET被优先选择。
例如,假设M为4,N为3,4个CORESET中包括2个配置了CSS配置的CORESET,以及2个配置了USS配置的CORESET,那么,优先选取2个配置了CSS配置的CORESET,再从配置了USS配置的2个CORESET中选取1个CORESET。可以理解,终端再从配置了USS配置的2个CORESET中选取1个CORESET时,可以基于CORESET的索引大小、与CORESET关联的SS的索引大小、CORESET中包括的资源数选取,在此不做限制。
本实施例中,如果所述终端在基于每个所述CORESET的搜索空间类 型,从M个所述CORESET中选取到的CORESET的数量为X、且M>X>N的情况下,可以进一步执行以下(4a)-(4c)中至少一项,以进一步从X个所述CORESET中选取N个CORESET。
(4a)基于每个所述CORESET的索引值,从X个所述CORESET中选取具有第一索引值的N个CORESET。
(4b)基于每个所述CORESET包括的资源数,从X个所述CORESET中选取资源数最多的N个CORESET。
(4c)基于与每个所述CORESET关联的SS的索引值,从X个所述CORESET中选取具有第二索引值的SS所关联的N个CORESET。
需要注意,关于(4a)-(4c)的实现过程可参照前述(1)-(3)中的相关描述,为避免重复,在此不再赘述。
此外,在M个所述CORESET中,配置了CSS配置的CORESET的数量为Y、且M>Y>N的情况下,所述终端可按照预定优先级顺序从Y个所述CORESET中选取N个CORESET;其中,所述预定优先级顺序包括以下(a)-(c)任一项。
(a)第一CORESET>第二CORESET>第三CORESET>第四CORESET>第五CORESET。
(b)第一CORESET>第三CORESET>第四CORESET>第二CORESET>第五CORESET。
(c)第一CORESET>第三CORESET>第二CORESET>第四CORESET>第五CORESET。
其中,前述(a)-(c)中,所述第一CORESET是与类型(Type)0 CSS关联的CORESET,所述第二CORESET是与Type 1 CSS关联的CORESET;所述第三CORESET是与Type 0A CSS关联的CORESET;所述第四CORESET是与Type 2 CSS关联的CORESET;所述第五CORESET是与Type 3 CSS关联的CORESET。
需要注意的是,根据CORESET的不同,前述的预定优先级顺序也可以不同,本实施例对此不做限制。
S322,基于N个所述CORESET,监听所述PDCCH。
基于前述方法实施例300的描述,为便于理解,下面进一步结合示例对方法实施例300的实现过程进行介绍,内容如下,应注意,图3b中所示的U表示上行,D表示下行。
假设网络侧配置了多个CORESET,如CORESET#0-4,且每个CORESET上配置至少一个SS,终端根据每个时间单元(也即前述的第一时间单元)上的子带的方向信息,如上行、下行,确定目标监听资源,如CORESET。
请结合参阅图3b,(图3b中的CORESET只为了做频域资源的示意,具体的监听时机(monitoring occasion)根据SS的配置确定),终端在PDCCH monitoring occasion上需要在多个CORESET/SS set上进行PDCCH监听,根据子带的方向信息,确定监听PDCCH的CORESET或SS set。
假设在CORESET#0-4中均包含searchspace配置,使得在该monitoring occasion上需要进行PDCCH监听。图3b中,在PDCCH的monitoring occasion上,CORESET#0对应的频域资源(也可理解为带宽)内因为存在上行subband/guardband,则终端不在CORESET#0上进行PDCCH监听,而CORESET#1/3/4关联的SS Set也配置了在当前时间单元进行PDCCH监听,且包含在下行subband内,则终端在这些CORESET#1/3/4上进行PDCCH监听。
一种实现方式中,如果终端只能支持在N(如2)个CORESET上进行PDCCH监听,那么,终端可进一步根据如下(1)-(4)中任一项所述的方式,从多个CORESET中选取2个CORESET,以进行PDCCH监听。
(1)选取CORESET索引最小的2个CORESET进行监听,即CORESET#1,3。
(2)选取包括资源数最多(也即带宽最大)的2个CORESET进行监听,即CORESET#1,4。
(3)根据SS的类型进行监听,例如,在配置了CSS监听的CORESET进行监听,例如CORESET#3,4配置了CSS的PDCCH监听,而CORESET#1只有USS的监听,则终端在CORESET#3,4上进行PDCCH监听。
可选地,对于多个CSS,还可以根据CSS的类型确定优先级,例如Type0>…>Type3,详见方法实施例300中的相关描述。
(4)根据索引值最小的SS关联的CORESETs进行监听,例如CORESET#1配置了searchspace#1,CORESET#3配置了searchspace#3,CORESET#4配置了searchspace#2的监听,则终端在CORESET#1,4上进行PDCCH监听。
需要说明的是,终端基于一个时间段确定监听的CORESET(s)/SS set(s),该时间段可以包括一个或者多个时间单元。终端在该时间段内只监听在所有monitoring occasion都有效(可用)的CORESET(s)/SS set(s);或者在时间段内定义参考时刻,根据参考时刻确定监听的CORESET(s)/SS set(s),在整个时间段内监听相同的CORESET(s)/SS set(s)。
本实施例中,在网络侧配置了多组CORESET配置的情况下,终端可进一步从多组CORESET配置确定出可用的CORESET配置,并进行PDCCH监听,由此进一步实现对PDCCH的有效监听。
如图4a所示,为本申请一示例性实施例提供的监听PDCCH的方法300的流程示意图,该方法400可以但不限于由终端执行,具体可由安装于终端中的硬件和/或软件执行。本实施例中,所述方法400至少可以包括如下步骤。
S410,终端根据第一时间单元上的第一信息,确定用于PDCCH监听的目标监听资源。
其中,所述第一信息包括子带的配置信息和/或保护带的配置信息。
可以理解,S410的实现过程可参照前述方法实施例200或300中的相关描述,为避免重复,在此不再赘述。
S420,根据所述第一信息,确定所述目标监听资源上的可用资源。
一种实现方式中,所述终端可以通过以下(1)-(2)中任一方式确定所述可用资源。
(1)针对所述目标监听资源,以索引值为a的资源块为起点的连续预定数量个资源块中不存在不可用资源,其中,a满足mod(RB idx,b)=0,RB idx表示资源块的索引值,b表示所述预定数量。所述预定数量可通过协议约定或高层信令配置,在此不做限制。
示例性的,如果从RB idx=n开始的6个RB内的任意一个资源块(如RE或RB)为不可用资源,则这6个资源块为目标监听资源中不可用作PDCCH监听的频域资源,也即是不可用资源,所述n满足mod(RB_idx,6)=0的RB_idx。
(2)所述目标监听资源中不存在不可用资源。
例如,如果目标监听资源中的任何一个资源(如RB或RE)不可用,则该目标监听资源为不可用资源。
前述(1)和(2)中,对于确定一个目标监听资源(如CORESET、SS set)是否监听,如果其中任意一个SS set/PDCCH candidate和不可用资源重叠,则不在该CORESET/SS set上进行监听。
此外,作为一种可能的实现方式,除前述(1)和(2)之外,对于确定一个目标监听资源(如CORESET、SS set)是否监听,还可以是,如果其中有一个SS set/PDCCH candidate在可用资源中,则确定目标监听资源为可用资源,以及后续在该目标监听资源上进行PDCCH监听。
S430,基于所述目标监听资源上的可用资源,监听所述PDCCH。
可以理解,S430的实现过程除了可参照前述方法实施例200或300中的相关描述之外,作为一种可能的实现方式中,S430的实现过程可以包 括:根据所述目标监听资源上的可用资源的集合,确定所述目标监听资源中的PDCCH候选资源;基于所述PDCCH候选(candidate)资源,监听所述PDCCH。
例如,按子带确定目标监听资源是否可用的颗粒度可能是50个RB,但是对于判断PDCCH candidare是否可用,是6个RB,可能出现其中1个RB不可用,其他5个可用,那么从PDCCH的角度就是这个6个RB都不可用。但是,如果从RB角度描述目标监听资源是否可用,那么,可能因为RB中存在一个RE不可用,因此这个RB不可用。
需要注意的是,在所述PDCCH候选资源中不存在RE为不可用资源的情况下,基于所述PDCCH候选资源,监听所述PDCCH;在所述PDCCH候选资源中存在RE为不可用资源的情况下,不监听所述PDCCH候选资源。
进一步,在所述目标监听资源中的至少部分监听资源对应的监听时机和/或频域资源的传输方向为下行的情况下,所述至少部分监听资源包括以下(1)-(3)中的至少一项。
(1)索引为#0的CORESET。
(2)用于波束失败恢复(Beam Failure Recovery,BFR)的CORESET。
(3)与指定类型CSS关联的CORESET,所述指定类型CSS包括Type-0CSS、Type-0A CSS、Type-1 CSS、Type-2 CSS中的至少之一。
对于前述(1)-(3)中的CORESET,可以理解为:如果配置了索引为#0的CORESET、用于波束失败恢复的CORESET或与指定类型CSS关联的CORESET,那么,与其对应的监听资源始终是下行,终端始终监听PDCCH。
进一步,基于前述方法实施例400的描述,为便于理解,下面结合示例对方法实施例400的实现过程做进一步介绍,内容如下。
终端根据子带的配置信息(如方向信息),和/或,保护带的配置信息, 确定CORESET中的可用资源,可以包含以下方式一和方式二。
方式一:参阅图4b,终端根据subband或者guardband的配置信息确定可用的RB、RE,如果PDCCH candidate中的任意有一个RE为不可用资源,则终端不进行该PDCCH candidate的监听。
可以理解,方式一中,不改变CORESET的配置及终端在该CORESET进行PDCCH的资源映射方式,只有PDCCH candidate的所有RE均可用时,终端才在该PDCCH candidate上进行监听。
方式二:参阅图4c,终端根子带的配置信息(如方向信息),和/或,保护带的配置信息确定可用的RB、RE,终端在确定CORESET的RB资源时,排除这些不可用的RB;例如,终端进一步排除如下的RB作为不可用资源,即如果从RB index=n开始的6个RB内的任意一个RE不可用,则这6个RB为不可用的CORESET资源,所述n满足mod(RB idx,6)=0的RB idx
排除了这些不可用的RB资源之后,网络侧可根据可用的RB资源进行PDCCH candidate的映射,终端也根据可用资源对应的PDCCH映射方式进行PDCCH监听。
因此可以理解,在该方式二中,网络配置的CORESET的资源集合中,只选取可用的RB资源进行PDCCH candidate的映射,即改变了PDCCH的资源映射方式,从而实现PDCCH的有效监听。
本实施例中,终端根据PDCCH candidate中RE是否为可用资源,进行PDCCH监听,和/或终端根据可用资源,确定PDCCH资源映射方式,并进行PDCCH监听,如此,避免了因为不可用资源而进行无用的PDCCH监听。同时,在本实施例给出的PDCCH监听机制下,网络侧可以更灵活的进行PDCCH传输。
