检测物理下行控制信道PDCCH的方法以及装置 技术领域
本申请涉及无线通信领域，并且更具体地，涉及检测物理下行控制信道的方法以及装置。
背景技术
在5G新空口(NR)的应用场景中，高可靠低时延通信(Ultra-Reliable and Low Latency communication,URLLC)业务代表一类有低时延和高可靠性需求的业务。为了提高可靠性和低时延的要求，可以在不同的波束范围和不同的发送接收站点(transmission and reception point，TRP)上发送和接收数据，从而使终端设备在不同的方向上接收网络设备的数据，提高数据传输的可靠性。然而，在多站传输场景下，终端设备可能需要在一个时隙传输两个或多个物理下行控制信道(physical downlink control channel，PDCCH)，因此盲检PDCCH的数目大幅度增加，从而增加终端设备盲检的检测功耗。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：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)、通用移动通信系统(universal mobile telecommunication system，UMTS)、第五代(5th generation，5G)系统或新无线(new radio，NR)等。
应理解，该通信系统中的网络设备可以是任意一种具有无线收发功能的设备或可设置 于该设备的芯片，该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，无线保真(Wireless Fidelity，WIFI)系统中的接入点(Access Point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者传输发送接收点(Transmission receiving point，TRP)等，还可以为5G，如NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
还应理解，该通信系统中的终端设备也可以称为用户设备(user equipment，UE)、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。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。
为便于理解本申请实施例，首先对本申请中涉及的几个术语做简单说明。
1、控制资源集合(control resource set，CORESET)：控制资源集合可以是用于传输下行控制信息(downlink control information，DCI)的资源集合，也可以称为控制资源区域，或物理下行控制信道资源集合。
对于网络设备而言，控制资源集合可以理解为发送物理下行控制信道(physical downlink control channel，PDCCH)所可能使用的资源的集合；对于终端设备而言，每个终端设备的PDCCH的搜索空间所对应的资源都属于该控制资源集合。或者说，网络设备可以从该控制资源集合中确定发送PDCCH使用的资源，终端设备可以根据该控制资源集合确定PDCCH的搜索空间。
其中，控制资源集合可以包括时频资源，例如，频域上可以是一段带宽，或者一个或 者多个子带等；时域上可以是一个或多个符号；一个控制资源集合在时频域上可以是连续或不连续的资源单元，例如，连续的资源块(resource block，RB)或者不连续的RB。
在本申请中，不同的波束方向对应不同的控制资源集合，多个控制资源集合组成控制资源集合组。在本申请实施例中，控制资源集合CORESET组数目和/或索引，可以有不同的名称，有时可以称为控制资源集CORESET池数目和/或索引、传输配置指示状态TCI state组数目和/或索引、参考信号CSI-RS数目和/或索引、同步信号块SSB数目和/或索引、波束组数目和/或索引。
以下表达中不同的控制资源集合组数目和/或控制资源集合组索引与不同的TRP数目和/TRP索引相对应。
2、配置信息或指示信息：配置信息或指示信息可以由网络设备配置，下发给终端设备，配置信息可以承载在物理广播信道(Physical Broadcast Channel，PBCH)、剩余最小系统信息(Remaining minimum system information，RMSI)、系统信息块(System Information Block，SIB)1、SIB2、SIB3，媒体接入控制元素(Media Access control-control element，MAC-CE)、下行控制信息(Down link control information，DCI)、无线资源控制(Radio Resource Control，RRC)以及系统信息中的任意一项；关联关系也可以由标准规定，或者网络设备和终端设备预先约定，也可以使用叫醒信号(wake-up signal，WUS)进行指示。当使用WUS进行指示的时候，当WUS有一级的时候，可以使用该级的TRP进行指示，当WUS有两级或者多级的时候，网络设备可以使用第二级的WUS进行指示。
3、同步信号块：同步信号块也可以称为同步信号/物理广播信道(synchronization signal/Physical broadcast channel，SS/PBCH block)，也可以简称为SSB，可以包含PBCH，主同步信号(primary synchronization signal,PSS)，辅同步信号(Secondary synchronization signal,SSS)中的至少一个。
此外，为了便于理解本申请实施例，作出以下几点说明。
第一，在本申请中，为便于描述，在涉及编号时，可以从0开始连续编号。例如，某一时隙中的第0个符号，可以是指该时隙的首个符号。当然，具体实现时不限于此。例如，也可以从1开始连续编号。例如，某一时隙中的第1个符号，也可以是指该时隙的首个符号。由于编号的起始值不同，同一个符号在时隙中所对应的编号也不同。
应理解，上文所述均为便于描述本申请实施例提供的技术方案而进行的设置，而并非用于限制本申请的范围。
第二，在下文示出的实施例中第一、第二以及各种数字编号仅为描述方便进行的区分，并不用来限制本申请实施例的范围。例如，第一时间单元、第二时间单元，其中，第一、第二用来区分不同的时间单元等。
第三，本申请实施例中，“的(of)”，“相应的(relevant)”和“对应的(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。“至少一个”是指一个或者多个，“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和c中的至少一项(个)，可以表示：a，或，b，或，c，或，a和b，或，a和c，或，b和c，或，a、b和c。其中a、b和c分别可以是单个，也可以是多个。
第四，本申请中的关联也可以称为映射，对应，相关，分配。当随机接入周期或随机接入集合与寻呼时机相关的时候，可以为该寻呼时机的终端设备在该随机接入周期内的随机接入时机上发送随机接入前导，可以用于请求寻呼消息，或上报波束，随机接入时机和SS/PBCH block或寻呼时机中的寻呼消息或寻呼指示关联的时候，也可以表示它们具有准共址(quasi co-located，QCL)关系，可以采用相同的时延扩展或相同的多普勒扩展或相同的平均增益，相同的平均时延，或相同的空域参数发送或接收信号，或采用相同的波束发送或接收信号。准共址的参数包含：多普勒扩展，多普勒频移，平均时延，时延扩展和空域接收参数中的至少一项。可以将QCL关系分为四类：'QCL-TypeA':{多普勒频移,多普勒扩展,平均时延,时延扩展}；'QCL-TypeB':{多普勒频移,多普勒扩展}；'QCL-TypeC':{多普勒频移,平均时延}；'QCL-TypeD':{空域接收参数}。

结合图4，对非连续接收(discontinuous reception，DRX)周期进行详细描述。在时域上，时间被划分成一个个连续的DRX周期(DRX Cycle)。DRX周期是用于描述DRX模式下OnDurationTimer重复出现的周期。一个DRX周期由“OnDurationTimer”和“Opportunity for DRX”组成。在OnDurationTimer的时间段内，UE监听PDCCH，从而可以接收下行信道的 数据。因此“OnDurationTimer”的时间段也可以称为激活期。“Opportunity for DRX”即可能的休眠时间，在该时间段内，UE关闭接收机，UE不监听PDCCH，不接收下行信道的数据以节省功耗。因此“Opportunity for DRX”的时间段，也可以称为休眠期。终端设备一旦检测到一个PDCCH，则终端设备将会启动一个InactiveTimer(激活定时器)，在该InactiveTimer内终端设备将要继续检测PDCCH。
DRX周期(DRX Cycle)的选择包含了减少UE功耗和业务延迟之间的平衡。一方面，长的DRX周期有益于减少UE的功耗。另一方面，当有新的数据传输时，短的DRX周期有利于更快的响应。DRX长周期是系统必须的配置，short DRX cycle为可选地配置。换句话说，当系统采用DRX长周期(long DRX cycle)时，DRX周期即是long DRX cycle，DRX周期的周期长度就是long DRX cycle的周期长度。当系统采用DRX短周期(short DRX cycle)时，DRX周期即是short DRX cycle,DRX周期的周期长度就是short DRX Cycle的周期长度。
下面将基于上面所述的本申请实施例涉及的共性方面，对本申请实施例进一步详细说明。
本申请实施例中，在多站进行数据传输的场景下，终端设备盲检PDCCH的数目大幅增加，从而增加终端设备的检测损耗。为降低终端设备的检测损耗，提出了一种检测PDCCH的方法。举例来说，终端设备接收网络设备发送的指示信息，该指示信息用于指示终端设备在第一时间单元检测物理下行控制信道PDCCH所使用的N个控制资源集合组的配置；根据在该第一时间单元检测到的PDCCH确定第二时间单元，终端设备在第二时间单元使用M个控制资源集合组的配置检测PDCCH；其中，控制资源集合组的配置包括控制资源集合组数目和/或控制资源集合组索引；N为大于等于1的正整数，M大于N。
图5是从设备交互的角度示出的本申请实施例提供的检测PDCCH的方法500的示意性流程图。如图所示，该方法500可以包括步骤510至步骤520。下面详细说明方法500中的各步骤。
需要说明的是，本申请提供的通信方法可以应用于无线通信系统中，例如，图1中所示的通信系统100中。处于通信系统中的通信装置之间可具有无线通信连接关系。例如，图1中所示的终端设备101分别可以与网络设备#1 102和网络设备#2 103之间具有无线通信连接关系，本申请对此不作限定。
在步骤510中，终端设备从网络设备接收指示信息。网络设备向终端设备发送指示信息。
具体的，该指示信息用于指示终端设备在第一时间单元检测物理下行控制信道PDCCH所使用的N个控制资源集合组的配置，即终端设备在第一时间单元使用N个控制资源集合组的配置检测PDCCH，其中N为大于等于1的正整数。该控制资源集合组的配置不仅包括控制资源集合组数目和/或控制资源集合组索引，还可以包括主TRP信息或默认TRP(Default S-TRP)信息。默认TRP信息表示的是基站使用一个TRP发送PDCCH的时候，该TRP表示CORESET高层参数索引指示的CORESET为发送状态，终端设备只检测该CORESET高层参数索引指示的CORESET，如图6(a)所示，终端设备使用单个TRP(S-TRP)的配置检测PDCCH，在持续定时器OndurationTimer内检测到C-RNTI加扰的PDCCH时，开启多个TRP(M-TRP)检测PDCCH，M-TRP在持续定时器OndurationTimer内检测PDCCH 之后进入休眠期(Deep sleep)。
本申请实施例中的控制资源集合组可以为TRP，或者也可以为CORESET池，或者也可以为CORESET集合，或者也可以为波束组，或者也可以为波束池，或者也可以为波束集合，或者也可以为参考信号组，或者也可以为参考信号池，或者也可以为参考信号集合，或者也可以为CORESET高层参数，或者也可以为其他表示TRP参数。控制资源集合组索引可以为TRP索引，或者也可以为CORESET池索引，或者也可以为CORESET集合索引，或者也可以为波束组索引，或者也可以为波束池索引，或者也可以为波束集合索引，或者也可以为参考信号组索引，或者也可以为参考信号池索引，或者也可以为参考信号集合索引，或者也可以为CORESET高层参数索引，或者也可以为其他表示TRP索引的索引。控制资源集合组数目可以为TRP数目，或者也可以为CORESET池数目，或者也可以为CORESET集合数目，或者也可以为波束组数目，或者也可以为波束池数目，或者也可以为波束集合数目，或者也可以为参考信号组数目，或者也可以为参考信号池数目，或者也可以为参考信号集合数目，或者也可以为CORESET高层参数数目，或者也可以为其他表示TRP索引的数目。在下文的描述中，选择控制资源集合组索引和/或控制资源集合组数目进行举例，控制资源集合组索引可以替换为TRP索引、CORESET池索引、CORESET集合索引、波束组索引、波束池索引、波束集合索引、参考信号组索引、参考信号池索引、参考信号集合索引；控制资源集合组数目可以替换为TRP数目、CORESET池数目、CORESET集合数目、波束组数目、波束池数目、波束集合数目、参考信号组数目、参考信号池数目、参考信号集合数目、CORESET高层参数数目、其他表示TRP索引的数目，本申请实施例不做限定。上述参考信号可以为信道状态信息参考信号，也可以为同步信号块，也可以为解调参考信号。

可选地，本申请实施例中的叫醒信号可以为PDCCH信号，也可以为序列信号。当为PDCCH信号时，可以为PDCCH配置专门的搜索空间。该搜索空间的周期可以是DRX周期的N1倍，N1可以为1,2,3,4,5,6,7,8，9,10,11,12,13，14,15,16中的部分或者全部的值；也可以为该搜索空间的周期，也可以与DRX的周期不相关，单独进行配置，周期的持续时间也可以单独进行配置，例如配置周期为现有的搜索空间searchSpace中的配置，网络设备可以配置或者协议可以规定与下一个DRX周期中的OndurationTimer关联的searchSpace周期，例如距离OndurationTimer最近的searchSpace周期。为了降低终端设备的盲检功耗，该searchSpace的持续时间可以为1或2或3或4个时隙。
可选地，所述指示信息的指示方式可以是隐式的指示方式，也可以是显示的指示方式。隐式的指示方式可以使用信号的特性指示，例如检测第一时间单元的PDCCH的控制资源组的配置可以为检测WUS的控制资源组的配置。隐式的指示方式也可以没有指示信息，直接使用配置信息确定检测第一时间单元的PDCCH的控制资源组的配置，如图6(b)所 示；隐式的指示方式也可以没有指示信息，直接使用协议规定的信息确定检测第一时间单元的PDCCH的控制资源组的配置，如图6(b)所示。显示的指示方式可以是信令中的字段进行指示。

可选地，指示信息指示的控制资源结合组的数目和/或索引为配置信息里配置的部分或全部控制资源集合组的数目和/或索引。
在一种可能的实施方式中，控制资源集合组的配置由指示信息和配置信息共同作用：指示信息指示控制资源集合组的配置为控制资源集合组数目，可以使用Y比特进行指示。示例性的，指示控制资源集合组数目的比特Y等于1，即通过1个比特位指示控制资源集合组数目，当比特位的比特值取0时，则表示控制资源集合组的数目为1个；当比特位的比特值取1时，则表示控制资源集合组的数目为2个；控制资集合组索引通过配置信息配置。示例性的，网络设备和终端设备预先约定好控制资源集合组索引的信息和/或数目信息。可选地，网络设备为终端设备使用配置信息配置控制资源集合组索引和/或数目信息。可选地，终端设备上报给网络设备控制资源集合组索引的信息。可选地，控制资源集合组的配置可以与其他信号相关联，大大节省了信令开销。可选地，其他信号可以为叫醒信号WUS、上一个非连续接收DRX周期内的PDCCH、信道状态指示参考信号CSI-RS、同步信号块SSB、物理下行控制信道PDCCH、物理下行共享信道PDSCH、MAC控制元素MAC-CE信令、无线资源控制RRC信令。与其他信号相关联可以表示为采用完全相同的所述控制资源组配置或部分相同的控制资源集合组配置。
在另一种可能的实施方式中，控制资源集合组的配置均由指示信息所指示，指示信息通过比特映射的方式指示PDCCH所对应的每一个控制资源集合组的配置状态，也就是说，指示信息指示控制资源集合组的配置为控制资源集合组数目和控制资源集合组索引，一个控制资源集合组的配置对应一个比特位和/或N个控制资源集合组的配置对应一个比特位。
示例性的，当一个控制资源集合组的配置对应一个比特位时，假设有两个控制资源集合组(分别记为控制资源集合组1和控制资源集合组2，控制资源集合组1关联TRP1，控制资源集合组2关联TRP2)，使用2个比特位进行指示，记为第一比特位和第二比特位。 当第一比特位指示控制资源集合组1，第一比特值为0时，则表示控制资源集合组1没有对应的PDCCH，即TRP1不发送PDCCH；当第一比特位指示控制资源集合组1，第一比特值为1时，则表示控制资源集合组1有对应的PDCCH，即TRP1发送PDCCH。当第二比特指示控制资源集合组2，第二比特值为0时，则表示控制资源集合组2没有对应的PDCCH，即TRP2不发送PDCCH；当第二比特指示控制资源集合组2，第二比特值为1时，则表示控制资源集合组2有对应的PDCCH，即TRP2发送PDCCH。可选地，N可以为2,3,4,5,6,7,8中的任意一个或者多个值。
可选地，当N个控制资源集合组对应一个比特位时，示例性的，假设有两个控制资源集合组(分别记为控制资源集合组1和控制资源集合组2，控制资源集合组1关联TRP1，控制资源集合组2关联TRP2)，使用1个比特位进行指示，记为第一比特位。第一比特位指示控制资源集合组1和控制资源集合组2，当第一比特值为0时，则表示控制资源集合组1和控制资源集合组2没有对应的PDCCH，即TRP1和TRP2均不发送PDCCH；当第一比特值为1时，则表示控制资源集合组1和控制资源集合组2有对应的PDCCH，即TRP1和TRP2均发送PDCCH。可选地，N可以为2,3,4,5,6,7,8中的任意一个或者多个值。

在另一种可能的实施方式中，控制资源集合组的配置均由指示信息所指示，可以用Y个比特位进行指示，也就是说，通过Y个比特位指示控制资源集合组数目和控制资源集合组索引。示例性的，假设指示控制资源集合组配置的比特位Y等于2，将2个比特位分别记为第一比特位和第二比特位。当控制资源集合组数目为2时，第一比特位指示控制资源集合组数目，第二比特位指示控制资源集合组索引。可选地，当控制资源集合组数目为1时，指示控制资源集合组数目的第一比特为0，第二比特指示控制资源集合组索引1或控制资源集合组索引2。可选地，当控制资源集合组数目为2时，可以通过1比特进行指示，即第一比特位指示控制资源集合组的数目，此时不需要指示控制资源集合组的索引。
在另一种可能的实施方式中，指示信息指示控制资源集合组的配置为控制资源集合组索引，配置信息配置控制资源集合组数目。示例性的，假设有两个控制资源集合组(分别记为控制资源集合组1和控制资源集合组2)，默认控制资源集合组为控制资源集合组1，通过2个比特指示控制资源集合组的索引，分别记为第一比特和第二比特。第一比特指示控制资源集合组1的索引0，第二比特指示控制资源集合组2的索引1。可选地，网络设备 与终端设备通过协议规定默认的控制资源集合组数目，网络设备通过指示信息指示控制资源集合组索引，即指示信息指示的控制资源集合组索引与发送数据PDCCH所对应的控制资源集合组相同，大大节省了信令开销。
在另一种可能的实施方式中，配置信息指示控制资源集合组的配置，配置信息配置控制资源集合组数目和/或索引。示例性的，网络设备通过配置信息配置第二时间单元内检测PDCCH的控制资源组的索引和数目，也配置了第一时间单元内检测PDCCH的的控制资源集合组的数目和/或索引，其中第一时间单元内检测PDCCH的的控制资源集合组的配置为的控制资源集合组的配置。假设第二时间单元内检测PDCCH的控制资源组有两个控制资源集合组(分别记为控制资源集合组1和控制资源集合组2)，默认所述控制资源集合组为控制资源集合组1，通过2个比特指示控制资源集合组的索引，分别记为第一比特和第二比特。第一比特指示控制资源集合组1的索引0，第二比特指示控制资源集合组2的索引1。可选地，网络设备与终端设备通过协议规定默认的所述控制资源集合组部分参数，网络设备通过配置信息指示所述控制资源集合组的剩余部分参数，其中部分参数为索引，则剩余部分参数为数目；或者部分参数为数目，剩余部分参数为索引，大大节省了信令开销。可选地，网络设备与终端设备通过协议规定默认的控制资源集合组所有参数，该参数包含数目和索引，进而大大节省了信令开销。可选地，网络设备通过配置信息指示控制资源集合组的索引。

在步骤520中，终端设备根据第一时间单元检测到的PDCCH确定第二时间单元，并在第二时间单元使用M个控制资源集合组的配置检测PDCCH，M大于N。网络设备根据 在第一时间单元发送的PDCCH确定第二时间单元，并在第二时间单元发送M个控制资源集合组的配置，M大于N。
具体的，终端设备根据第一时间单元检测到的PDCCH确定第二时间单元，即根据第一时间单元结束的时刻确定第二时间单元开启的时刻，或者根据检测到PDCCH位置之后的X个符号或时隙的时刻确定第二时间单元开启的时刻。终端设备在第二时间单元使用M个控制资源集合组的配置检测PDCCH，所述M个控制资源集合组的配置为默认发送PDCCH的TRP对应的控制资源集合组的配置。

可选地，终端设备使用单个TRP关联的控制资源集合组的配置检测PDCCH，当终端设备检测到小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)加扰的PDCCH时，假设网络设备进行TRP的切换，该切换可以从一个TRP切换到另一个TRP，即终端设备使用切换后的TRP关联的控制资源集合组的配置检测PDCCH；或者从一个TRP切换到多个TRP，即终端设备使用切换后的多个TRP关联的多个控制资源集合组的配置，完成PDCCH的检测。可选地，当终端设备检测到一个C-RNTI加扰的PDCCH之后的X个符号或时隙内网络设备不能有多个TRP发送PDCCH，即检测到C-RNTI加扰的PDCCH之后的X个符号或时隙用于预留时间开启多个TRP或切换TRP进行检测PDCCH。

示例性的，当DCI为GTS信号时，终端设备不检测从DCI到DCI调度的物理下行共享信道(physical downlink shared channel，PDSCH)之间的PDCCH；当DCI不为GTS信号时，终端设备检测从DCI到DCI调度的PDSCH之间的PDCCH。可选地，当DCI信号为GTS信号时，终端设备不检测从DCI到指定时间之间的PDCCH；当DCI信号不为GTS信号时，终端设备检测从DCI到指定时间之间的PDCCH。
