准共址信息的配置方法、网络设备及用户设备
相关申请的交叉引用
本申请主张在2018年5月11日在中国提交的中国专利申请号No.201810450348.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种准共址信息的配置方法、网络设备及用户设备。
背景技术
在第五代(5 Generation，5G)新空口(NR)移动通信系统的设计中，用户设备(UE)需要通过搜索空间配置，确定控制信道的时域检测位置，而搜索空间配置中会关联控制资源集(Control Resource set，CORESET)，CORESET中配置了控制信道出现的频域位置，带宽，传输配置指示(TCI)等信息。
TCI指定了CORESET与参考信号的准共址(Quasi Co-Location，QCL)关系，TCI中可能包含多个QCL关系，具体的控制信道使用哪个QCL关系可以通过媒体介入控制层控制元素(MAC Control Element，MAC CE)配置。
如果两个天线端口的信号满足QCL关系，那么从这两个天线端口发射的两个信号，所经历的大尺度特性相似。大尺度特性包括多普勒频移(Doppler shift)、多普勒扩展(Doppler spread)、平均时延(average delay)、时延扩展(delay spread)、空间接收参数(Spatial Rx parameter)等。假设两个天线端口是QCL的，有利于接收机处理，比如从一个天线端口上获得的信道估计结果，可用于另一个天线端口。具体的，QCL类型(QCL type)可包括：
QCL类型A，其准共址参数包括：多普勒频移、多普勒扩展、平均时延和时延扩展；
QCL类型B，其准共址参数包括：多普勒频移和多普勒扩展；
QCL类型C，其准共址参数包括：平均时延和多普勒频移；
QCL类型D，其准共址参数包括：空间接收参数。
对于通过高层无线资源控制(RRC)信令配置的搜索空间和CORESET，在传输调度用户专属业务信道的调度控制信息时，由于物理下行控制信道(Physical Downlink Control Channel，PDCCH)的QCL关系可以通过RRC信令结合MAC CE确定，因此，用户设备和基站(gNB)能够达成一致的理解。
对于物理广播信道(Physical Broadcast Channel，PBCH)配置的CORESET#0，通常用来传输剩余的最小化的系统信息(RMSI)的调度控制信道。在配置CORESET#0时，可以利用PBCH中的8比特来指示CORESET的带宽，持续时间长度和PDCCH检测(monitoring)的时域资源位置。CORESET#0还可以用来传输寻呼(paging)、OSI和RAR等的调度控制信道。由于这些信息是广播信息，在与每个SSB编号(SSB index)关联的CORESET#0中均会传输，因此CORESET#0通常并不会指定QCL关系。这里，在5G NR中，主同步信号(PSS)、辅同步信号(SSS)和PBCH共同构成一个SSB(SS/PBCH block)，SSB在时域上共占用4个OFDM符号，频域共占用240个子载波(20个PRB)。
但是，当CORESET#0中传输用于调度单播物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的PDCCH时，如果仍然没有相对应的QCL关系，则会导致基站和UE对CORESET#0的理解不一致。
举例来说，基于相关技术中的机制，高层信令为UE配置了用户设备专属的搜索空间，这个搜索空间关联CORESET#0，搜索空间的类型是UE specific。即用户设备将在CORESET#0中检测用户设备专属的搜索空间，获取PDSCH的调度信息。那么，当UE的位置发生变化，用户接收到的信号较强的SSB index可能发生了变化，相应的接收RMSI的时域资源位置就会发生变化。也即在这种情况下，UE接收PDCCH的位置变成了与新的SSB index关联的CORESET位置，而当前的基站并不知道，因此就会出现传输用于调度unicast PDSCH的PDCCH位置和UE检测的位置不同的情况，导致UE无法接收到控制信道。

请参见图1，图1示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括用户设备11和网络设备12。其中，用户设备11也可以称作终端、用户终端或UE(User Equipment)，用户设备11可以是手机、平板 电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本公开实施例中并不限定用户设备11的具体类型。网络设备12可以是基站和/或核心网网元，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，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，在本公开实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
基站可在基站控制器的控制下与用户设备11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与用户设备11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从用户设备11到网络设备12)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从网络设备12到用户设备11)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
如图2所示，本公开的实施例提供了一种准共址信息的配置方法，也可以说是一种传输配置指示(TCI)信息的配置方法，应用于网络设备，这里，网络设备具体可以是基站，如图2所示，该方法具体包括以下步骤：
步骤21，配置或确定CORESET#0或关联CORESET#0的搜索空间的TCI状态信息。
在以上步骤中，网络设备可以配置或确定CORESET#0的TCI状态信息，或者，配置或确定关联了CORESET#0的搜索空间的TCI状态信息，这里，TCI状态信息包括有QCL关系。通过以上配置或确定动作，使得CORESET#0具备了QCL关系，从而可以使得网络设备与用户设备对CORESET#0的理解一致，有利于用户设备对控制信道的接收。
本公开实施例进一步提供了上述步骤21的多种更为具体的实现方式。
实现方式1：
对于搜索空间配置，当关联了CORESET#0，并且，搜索空间类型为UE specific的情况下，可以额外针对该搜索空间或者说该搜索空间对应的CORESET#0配置TCI状态信息。配置方式可以是在搜索空间中增加相应的信息，或是配置高层信令(RRC信令或MAC CE)指示其TCI状态信息或QCL关系。比如配置的PDCCH接收所关联的解调参考信号(Demodulation Reference Signal，DMRS)端口与某个SSB编号(SSB index)所对应的参考信号(例如同步信号或PBCH所关联的DMRS端口)是QCL的。用户设备(UE)假设该搜索空间的PDCCH接收所关联的DMRS天线端口是与TCI state配置的下行参考信号准共址的。
上述通过配置高层信令(RRC信令或MAC-CE)指示TCI状态信息或QCL对应关系的方式，由于相关技术中的信令中MAC CE指示的TCI状态编 号(TCI State ID)的取值来自于CORESET配置中的TCI状态信息，而CORESET#0中并没有TCI状态信息配置，因此需要预定义或是配置CORESET#0的TCI-state PDCCH信息，TCI-state PDCCH信息可以是一个TCI状态TCI-state集合，集合中每个TCI状态定义与SSB index或CSI-RS或csi-RS-for-tracking等参考信号的QCL关系，集合中TCI状态的个数可以是预定义的，或是配置时给出的，也可能跟SSB的个数有关。这样可以通过MAC CE为用户配置TCI state ID，取值就可以来源于预定义或配置的CORESET#0的TCI state集合。
举例来说，TCI状态的一种配置方式如下所示，上述的TCI-state PDCCH信息或者说为CORESET#0配置的TCI-state集合中的每个TCI状态可以沿用如下的配置形式。

Figure PCTCN2019081874-appb-000002
在本公开实施方式中，为了描述的方便，将上述配置IE中的referenceSignal中的不同参考信号用参考信号类型表示。
每个TCI状态信息(TCI-state信息)也可以采用简化的形式，参考信号为SSB，QCL类型也可以是确定的某种类型，例如与UE接收Type0-PDCCH公共搜索空间时的准共址类型是一致的。甚至，每个TCI state中都只给出参考信号SSB和对应的SSB index，QCL类型是预定义的与UE接收Type0-PDCCH公共搜索空间时的准共址类型是一致的。
具体的，在该实现方式1中，网络设备可以通过高层信令，配置与CORESET#0关联的TCI状态信息；或者，预先定义与CORESET#0关联的TCI状态信息；其中，所述CORESET#0可以是通过主信息块(Master Information Block，MIB)配置的。这里，高层信令可以是RRC参数配置信令等RRC信令或MAC CE。
在预先定义了与CORESET#0关联的TCI状态信息时，网络设备和用户设备可以基于相同的预先定义(如通过相关标准进行定义)，确定相同的TCI状态信息。
在该实现方式1中，网络设备也可以在所述搜索空间的配置信息中携带 TCI状态信息，或者，通过高层信令，配置关联所述搜索空间的TCI状态信息，从而实现对关联了CORESET#0的搜索空间的TCI状态信息的配置。
具体的，作为一种实现方式，所述TCI状态信息可以包括：至少一个TCI状态，其中，所述TCI状态至少包括TCI状态编号、QCL类型、参考信号类型和参考信号编号中的一种。可选的，所述至少一个TCI状态可以是N个TCI状态，这里，所述N为预定义的一个正整数，且所述TCI状态编号对应的参考信号类型为SSB。
考虑到实际应用场景：
所述N，M可以小于或等于SSB的最大个数；
或者，所述N，M小于或等于64；
或者，所述N，M小于或等于CORESET#0所在小区可以发送的SSB的最大个数，其中CORESET#0所在小区可以发送的SSB的最大个数根据所述小区的载波间隔和/或载频确定；
或者，所述N，M小于或等于CORESET#0所在小区实际发送的SSB个数。由于所述至少一个TCI状态可能包括大于或等于2个的TCI状态，本公开实施例中网络设备还可以通过高层信令，将所述至少一个TCI状态中的一个指示给用户设备。这里，高层信令可以是RRC参数配置信令等RRC信令或MAC CE。
作为另一种实现方式，所述TCI状态信息可以包括：M个SSB编号，其中所述M为正整数。由于所述M个SSB编号可能包括大于或等于2个的SSB编号，本公开实施例中网络设备还可以通过高层信令，将所述M个SSB编号中的一个指示给用户设备。这里，高层信令可以是RRC参数配置信令等RRC信令或MAC CE。如下表1是一种简化的预定义的或是配置的用于CORESET#0的用户专属PDCCH接收的TCI状态信息示例，包括64个SSB编号，对应的参考信号类型为SSB。

Figure PCTCN2019081874-appb-000004
表1 CORESET#0的TCI状态信息
实现方式2：
定义一定的规则确定关联的TCI状态信息，这里主要是与SSB index的QCL关联关系。基于UE的测量信息，设定一定的门限值或将当前所关联的SSB index的信号强度作为门限值，基于门限值和UE的测量信息确定当前关联的TCI状态信息。例如，基于用户测量的各SSB的信道或信号强度，当一个或多个SSB连续M个测量上报值均高于一定门限时或均高于当前所关联的SSB时，更新关联的SSB为测量值最大的SSB的index，UE假设该搜索空间的PDCCH接收所关联的DMRS天线端口是与该测量值最大的SSB准共址的。在这种情况下需要预定义或者由基站配置M值。
具体的，在该实现方式2中，网络设备可以根据SSB上的信号测量信息，得到符合预设条件的第一SSB；确定所述第一SSB作为所述TCI状态信息。
具体的，作为一种可选方式，所述预设条件包括：至少一个SSB中的信号强度测量值最大的SSB，所述至少一个SSB包括：连续X个信号强度测量值均大于第一门限值的SSB，所述第一门限值为预设门限值或所述搜索空间当前关联的SSB的信号强度测量值，所述X为正整数。
这里，所述X的取值是预定义或者由网络设备配置的，且在所述X的取值是由网络设备配置时，所述配置方法还包括：将所述X的取值发送给用户设备。
实现方式3：
通过高层信令配置CORESET#0，通常情况下CORESET#0是通过PBCH中的MIB信息配置的，这里通过高层信令对CORESET#0进行重新配置，增 加TCI状态信息。并且约定当用户设备接收到搜索空间配置，其关联的CORESET ID为0，并且搜索空间类型为UE specific的情况下，UE假设该搜索空间的PDCCH接收所关联的DMRS天线端口是与增加的TCI状态信息配置的下行参考信号准共址的。对于使用CORESET#0的广播信息的控制信道接收，则仍然按照PBCH配置的CORESET#0配置接收，即不需要利用增加的TCI状态信息。
在该实现方式3中，网络设备可以通过高层信令，发送CORESET#0的配置信息，其中，所述CORESET#0的配置信息包括所述TCI状态信息，其中，所述TCI状态信息应用于关联了CORESET#0的UE专属搜索空间的PDCCH的接收。这里，高层信令可以是RRC参数配置信令等RRC信令或MAC CE。
实现方式4：
对于UE的搜索空间配置，当关联了CORESET#0，并且，搜索空间类型为UE specific的情况下，根据搜索空间配置参数能够确定调度unicast PDSCH的PDCCH的monitor的时域资源位置，根据该搜索空间与type0的搜索空间的时域位置的overlap情况确定其与SS/PBCH block或者说是与SS/PBCH接收所关联的DMRS端口的QCL关系。例如通过周期和偏移参数，“monitoringSlotPeriodicityAndOffset”能够确定monitor的时隙资源位置，monitoringSymbolsWithinSlot确定时隙内的符号位置，通过这些参数，确定monitor的具体时域资源位置。由于SSB index与RMSI的PDCCH(也即type0的PDCCH)monitoring window有对应关系，即通过SSB中的PBCH配置能够获得type 0搜索空间也即RMSI的调度PDCCH搜索空间的时域资源位置。
当配置的调度unicast PDSCH的PDCCH的搜索空间参数指示的monitoring时域位置与type 0搜索空间的monitoring时域位置全部或者部分重合时，则用户设备假设该搜索空间内的调度unicast PDSCH的PDCCH接收所关联的DMRS端口与重合的type0的搜索空间内的PDCCH接收所关联的DMRS端口具有相同的准共址关系。相同的准共址关系，意味着它们与相同DMRS端口具有准共址关系，该DMRS端口是SS/PBCH接收所关联的DMRS端口，或者说他们都与相同的SS/PBCH block是准共址的。
上述的部分重合出现在一些情况下，例如用户专属的搜索空间周期可以与type0的搜索空间的周期不同，比如type0的搜索空间周期为20ms，用户专属搜索空间的周期为10ms，那么只会在每20ms type0的搜索空间出现的时域位置才会重合，而不是每个10ms都重合。
在该实现方式4中，网络设备可以根据所述搜索空间的配置参数，确定用于检测PDCCH的第一时域资源位置，所述PDCCH用于调度单播PDSCH；确定与第一时域资源位置有重叠的类型0的PDCCH公共搜索空间；将第一DMRS端口或第二DMRS端口或第一SS/PBCH block，作为传输配置指示TCI状态信息；
其中，所述第一DMRS端口为：该类型0的PDCCH公共搜索空间的PDCCH接收关联的DMRS端口；所述第二DMRS端口为：与所述第一DMRS端口准共址的SS/PBCH接收所关联的DMRS端口；所述第一SS/PBCH block为：与所述第一DMRS端口准共址的SS/PBCH block。
通过以上不同的实现方式，本公开实施例的网络设备可以配置或者确定CORESET#0的TCI状态信息，或者配置或确定关联了CORESET#0的搜索空间的TCI状态信息，使得CORESET#0具备了QCL关系，从而可以使得网络设备与用户设备对CORESET#0的理解一致，有利于用户设备对控制信道的接收。
下面将进一步介绍本公开实施例中用户设备的具体动作。如图3所示，本公开的实施例提供了一种准共址信息的配置方法，应用于用户设备，如图3所示，该方法具体包括以下步骤：
步骤31，获得CORESET#0或关联CORESET#0的搜索空间的TCI状态信息。
步骤32，根据所述TCI状态信息，确定与PDCCH的接收所关联的DMRS端口准共址的参考信号和/或准共址类型。
