具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括用户终端(User Equipment，UE)11和网络侧设备12，其中，用户终端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，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)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终端11的具体类型。网络侧设备12可以是基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备12也可以是小站，如低功率节点(LPN：low power node)pico、femto等小站，或者网络侧设备12可以接入点(AP，access point)；基站也 可以是中央单元(CU，central unit)与其管理是和控制的多个传输接收点(TRP，Transmission Reception Point)共同组成的网络节点。需要说明的是，在本公开实施例中并不限定网络侧设备12的具体类型。
请参见图2，图2是本公开实施例提供的一种公共下行控制信道传输方法的流程图，如图2所示，包括：步骤201、用户终端接收网络侧设备发送的目标信号，其中，用于传输公共下行控制信道的资源集合(CORESET)与所述目标信号关联；
步骤202、用户终端根据所述目标信号确定所述资源集合，并在所述资源集合接收所述网络侧设备发送的公共下行控制信道。
其中，上述目标信号可以是同步接入信号块(SS block)、RMSI、随机接入过程中的消息2(Msg2)或者随机接入过程中的消息4(Msg4)等等。而上述公共下行控制信道可以是公共物理下行控制信道(common Physical Downlink Control Channel，common PDCCH)，而上述资源集合可以理解为用于传输上述公共下行控制信道的资源。
另外，上述资源集合与所述目标信号关联可以是，上述资源集合与上述目标信号占用的资源存在特定关系，或者可以是，上述资源集合由上述目标信号指示，或者可以是，上述资源集合中传输公共下行控制信道采用的波束与上述目标信号传输采用的波束存在特定关系，或者可以是上述资源集合为协议预定义的与上述目标信号存在特定关系等等，对此本公开实施例不作限定。上述资源集合与所述目标信号关联进一步可以理解为，用户终端通过上述目标信号可以确定上述资源集合。
用户终端在接收到上述目标信号后，就可以确定上述资源集合，进而在该资源集合接收网络侧设备发送的公共下行控制信道。且可以是显式或者隐式确定上述资源集合。
需要说明的是，上述方法中，由于用于输公共下行控制信道的资源集合与所述目标信号关联，从而可以实现用于传输下行控制信道的资源可以根据目标信号进行灵活调整，以提高下行控制信道传输的灵活性。且用于输公共下行控制信道的资源集合与所述目标信号关联，用户终端通过目标信号可以确定该资源集合，从而网络侧设备不需要全向发送，也不需要进行波束扫描， 用户终端就可以接收到下行控制信道，以节约传输资源、用户终端和网络侧设备的功耗。且还可以实现多波束传输公共下行控制信道。
作为一种可选的实施方式，上述目标信号包括同步接入信号块。
该实施方式中，可以实现用于传输公共下行控制信道的资源集合与同步接入信号块关联，从而用户终端通过同步接入信号块可以确定用于传输公共下行控制信道的资源集合，这样可以减少信令的传输，以节约传输资源。另外，上述同步接入信号块可以包括主同步信号(PSS，Primary Synchronization Signal)、次同步信号(SSS，Secondary Synchronization Signal)和物理广播信道(PBCH，Physical Broadcast Channel)信号，其中PBCH承载MIB。
在一些可选的实施例中，所述资源集合占用的OFDM符号与所述同步接入信号块占用的OFDM符号相同，且所述公共下行控制信道的传输周期与所述同步接入信号块的传输周期相同。
该实施方式中，可以实现公共下行控制信道与同步接入信号块占用相同的OFDM符号，从而用户终端可以直接在接收同步接入信号的OFDM符号上接收公共下行控制信道，在提高公共下行控制信道传输的灵活性的同时，还可以减少用户终端和网络侧设备的功耗，因为减少或者不需要进行波束扫描。
在一些可选的实施例中，所述资源集合占用的时频资源与所述同步接入信号块占用的时频资源FDM。
该实施方式中，可以实现上述资源集合和同步接入信号块占用的时频资源FDM，即上述资源集合与同步接入信号块占用相同的OFDM符号，但在频域上占用不同频域资源，可以节约网络资源。
在一些可选的实施例中，所述公共下行控制信道与所述同步接入信号块在相同OFDM符号上采用相同的波束传输。
该实施方式，可以实现公共下行控制信道与所述同步接入信号块采用相同的波束传输，从而可以提高公共下行控制信道的传输性能，且用户终端可以使用相同的波束接收所述公共下行控制信道与所述同步接入信号块，以及减少波束训练和波束切换。
在一些可选的实施例中，所述资源集合的配置信息的全部内容由协议预 定义；或者
所述资源集合的配置信息部分或者全部内容通过所述同步接入信号块中的MIB进行配置。
该实施方式中，可以实现资源集合的配置信息由协议预定义，这样可以减少信令开销。另外，还可以实现资源集合的配置信息部分或者全部内容通过MIB进行配置，从而可以提高资源集合的灵活性。且用户终端通过协议预定义或者通过上述MIB确定上述配置信息后，可以根据上述配置信息在上述资源集合内检测接收公共下行控制信道。
在一些可选的实施例中，上述资源集合的配置信息包括如下一项或者多项：CCE与REG的映射关系；PDCCH候选资源(candidate)与CCE的映射关系；DMRS端口模式信息；资源大小信息；相对于所述同步接入信号块的资源位置。
通过上述配置信息用户终端可以准确地确定资源集合的配置，以准确接收到公共下行控制信道。另外，上述候选资源(candidate)也可以称作候选位置。
关于上述介绍的资源集合占用的正交频分复用技术OFDM符号与所述同步接入信号块占用的OFDM符号相同的实施方式，可以参见图3和图4进行举例：该举例中，公共下行控制信道与SS block相关。传输公共下行控制信道的资源集合(CORESET)与SS block所在的OFDM符号相同，并与SS block所占的时频资源FDM。公共下行控制信道与对应SS block传输所使用的波束方向相同，传输周期也相同。示意图如图3或图4所示。假设一个同步接入信号块组(SS block burst)内包含的SS block的个数为2，SS block的传输周期为N＝20个slot，slot的长度为14个OFDM符号。由图3或图4可见，公共下行控制信道的CORESET的时域位置与SS block的时域位置相同，但是频域位置不同。图中，CORESET1内传输的公共下行控制信道与SS block1在相同的波束上传输，CORESET2内传输的公共下行控制信道与SS block2在相同的波束上传输。公共下行控制信道传输的周期与SS block相同。
另外，在该举例中，在公共CORESET内传输的公共下行控制下信道的相关参数由协议预定义，例如CORESET的资源分配(固定大小且位于SS  block频域的一侧或者两侧)、映射规则和使用的DMRS pattern等。
或者，公共CORESET的资源分配信息由MIB通知，例如通知公共CORESET所占时频域资源的大小以及相对于SS block所占资源的偏移值。在这种情况下，用户终端需要首先正确接收到MIB，并解析出公共CORESET的资源分配信息，进而在与SS block相同的波束上检测接收公共下行控制信道。用户终端可以在出现SS block的时域位置上根据预定义的参数配置或者根据MIB通知的资源位置上并在对应SS block所在的波束上检测接收公共下行控制信道。
在一些可选的实施例中，所述资源集合的配置信息通过所述同步接入信号块和/或协议预定义确定。
其中，上述配置信息可以包括上一实施方式的描述配置信息中的全部或者部分内容，且该配置信息还可以包括上述资源集合的时域信息，该时域信息可以与上述同步接入信号块所占用的时域位置存在特定关系。
该实施方式中，由于配置信息通过所述同步接入信号块和/或协议预定义确定，这样用户终端可以通过上述同步接入信号块和/或协议预定义的内容确定资源集合，进而接收到公共下行控制信道。且用户终端通过协议预定义或者通过上述MIB确定上述配置信息后，可以在上述资源集合内检测接收公共下行控制信道。进一步，可以根据该配置信息确定上述资源集合，并在该资源集合内检测接收公共下行控制信道。
在一些可选的实施例中，一个同步接入信号块对应至少一个用于传输公共下行控制信道的资源集合，且所述配置信息由所述同步接入信号块中的MIB显式和/或隐式指示，或者所述配置信息与所述同步接入信号块之间存在协议预定义关系。
其中，上述MIB显式指示可以是，该MIB中包括指示上述配置信息的指示信息，例如：上述同步接入信号块的波束相关参数QCL指示公共下行控制信道的DMRS与同步接入信号块之间的特定关系，从而用户终端通过上述同步接入信号块可以确定上述资源集合。或者上述隐式指示可以是上述配置信息与上述MIB传输所占用的资源的配置信息存在预设关系，例如：公共下行控制信道的周期与MIB的周期相同，或者使用的波束相同等，即用户终端 通过MIB可以确定上述资源集合的配置信息，通过隐式指示可以节约MIB的开销。上述配置信息与所述同步接入信号块之间存在协议预定义关系可以是，上述配置信息与同步接入信号块所占用的资源的配置信息存在协议预定义关系。
该实施方式，所述配置信息由所述同步接入信号块中的MIB显式和/或隐式指示，或者所述配置信息与所述同步接入信号块之间存在协议预定义关系，从而可以提高资源集合的灵活性。
在一些可选的实施例中，一个同步接入信号块中的MIB通知该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合的时频位置。
该实施方式中，由于资源集合的时频位置可以通过MIB通知，可以进一步提高公共下行控制信道的灵活性。
在一些可选的实施例中，一个同步接入信号块对应至少一个用于传输公共下行控制信道的资源集合的时频位置，其中：一个同步接入信号块与该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合位于同一时隙slot内，且所述至少一个用于传输公共下行控制信道的资源集合位于所述同步接入信号块之前；或者
一个同步接入信号块与该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合位于同一slot内，且所述至少一个用于传输公共下行控制信道的资源集合位于所述同步接入信号块之后；或者
一个同步接入信号块与该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合位于同一slot内相同OFDM符号；或者
一个同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合位于传输该同步接入块的slot之外的一个或者多个slot；或者
一个同步接入信号块与该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合所占用的频域资源相同。
该实施方式中，可以实现一个同步接入信号块对应至少一个用于传输公共下行控制信道的资源集合的时频位置，即用户终端可以根据一个同步接入信号块确定至少一个传输下行控制信道的资源集合的时域位置，以接收至少一个公共下行控制信道。以及还可以实现一个同步接入信号块与对应的至少 一个的slot的关系，从而可以进一步提高公共下行控制信道传输的灵活性。另外，需要说明的是，上述描述的同步接入信号和资源集合的关系可以是协议预定义的，或者用户终端预先配置的等。
需要说明的是，该实施方式中，对同步接入信号块与资源集合所占用的频域资源相同，也可以结合上述限定的slot位置结合实现，例如：一个同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合位于传输该同步接入块的slot之外的一个或者多个slot，且一个同步接入信号块与该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合所占用的频域资源相同。且由于上述一个同步接入信号块与该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合所占用的频域资源相同，从而可以减少信令开销，因为不需要指示资源集合所占用的频域资源。用户终端可以根据接收到同步接入信号的频域资源，在对应的时域资源中的相同频域资源上接收公共下行控制信道。
需要说明的是，该实施方式中，描述的上述同步接入信号块与该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合之间关系可以是通过上述MIB通知的，或者协议预定义的，对此本公开实施例不作限定。
在一些可选的实施例中，一个同步接入信号块的MIB通知或者协议预定义该同步接入信号块对应的至少一个用于传输公共下行控制信道的资源集合的周期。
其中，上述由于用于传输公共下行控制信道的资源集合的周期可以通过MIB或者协议预定义，从而可以进一步提高公共下行控制信道的灵活性。
在一些可选的实施例中，所述公共下行信道信号传输所使用的波束与对应同步接入信号块传输所使用的波束相同；或者
所述公共下行信道信号传输所使用的波束通过对应同步接入信号块中的MIB指示。
该实施方式中，由于公共下行信道信号传输所使用的波束与对应同步接入信号块传输所使用的波束相同，从而用户终端可以使用相同的波束接收公共下行信道信号和同步接入信号块，以减少波束切换。另外，由于公共下行信道信号传输所使用的波束通过对应同步接入信号块中的MIB指示，这样可 以实现同步接入信号块和公共下行控制信道可以使用不同的波束发送，且用户终端可以使用不同的波束接收同步接入信号块和公共下行控制信道，以提高传输的灵活性。
下面以公共下行控制信道的资源集合(CORESET)以及相关参数通过MIB进行指示进行举例说明。公共下行控制信道传输时所在的波束可以与对应SS block所在波束相同，也可以不同。当公共下行控制信道传输所在的波束与对应SS block不同时，可以通过MIB中携带的信息进行指示。公共下行控制信道传输的公共CORESET可以位于SS block所占时频域资源之前，也可以位于SS block所占时频域资源之后，MIB配置CORESET的资源位置时可以在传输SS block的相同slot内为CORESET配置资源也可以在传输对应SS block的slot之外的一个或者多个slot内为CORESET配置资源。该举例中，假设一个slot包含14个OFDM符号，一个SS block占据4个OFDM符号。
公共下行控制信道的CORESET位于SS block之前，且一个SS block中的MIB配置公共下行控制信道的至少一个CORESET。如图5所示，不同CORESET可以TDM或者FDM。不同的CORESET所使用的波束方向可以与对应SS block相同，也可以配置不同的波束方向。当然，一个SS block可以对应多个公共下行控制信道的CORESET，所述多个公共下行控制信道的CORESET对应于相同或者不同的波束方向。
另外，公共下行控制信道的CORESET位于SS block之后，且一个SS block中的MIB配置公共下行控制信道的至少一个CORESET。如图6所示，不同CORESET可以TDM或者FDM。不同的CORESET所使用的波束方向可以与对应SS block相同，也可以配置不同的波束方向。当然，一个SS block可以对应多个公共下行控制信道的CORESET，所述多个公共下行控制信道的CORESET对应于相同或者不同的波束方向。
另外，公共下行控制信道的CORESET位于对应SS block所在的slot之外的其他一个或者多个slot，且一个SS block中的MIB配置公共下行控制信道的至少一个CORESET。如图7所示，不同CORESET可以TDM或者FDM。不同的CORESET所使用的波束方向可以与对应SS block相同，也可以配置不同的波束方向。当然，一个SS block可以对应多个公共下行控制信道的 CORESET，所述多个公共下行控制信道的CORESET对应于相同或者不同的波束方向。
在一些可选的实施例中，MIB配置的CORESET所占用的带宽，可以在SS block传输带宽之内，也可以与SS block传输带宽相同，也可以在SS block传输带宽之外的其他带宽，对此本公开实施例不作限定。
在一些可选的实施例中，所述资源集合的配置信息的部分或者全部内容通过所述同步接入信号块中的MIB以表格索引的方式指示，其中，所述表格索引为协议预定义的配置信息表格中的索引；或者
所述同步接入信号块中的MIB通知所述配置信息中的部分信息，所述配置信息中的另一部分信息由协议预定义。
该实施方式中，可以实现通过表格索引来指示配置信息，从而减少信令开销。以及还可以实现配置信息的部分由MIB通知，另一部分信息由协议预定义，从而可以减少MIB的开销。且由MIB通知的部分信息可以是配置信息与同步接入信号块存在一定关联的信息，例如：频域位置和时域位置等相关信息，而其他内容通过协议预定义，例如CCE-to-REG的映射关系，PDCCH-to-CCE的映射关系、检测周期和波束方向相关信息等均通过协议定义。
在一些可选的实施例中，所述表格索引用于索引所述配置信息的部分或者全部内容的组合；或者所述表格索引用于索引所述配置信息中部分或者全部内容中的各项内容。
其中，上述表格索引用于索引上述配置信息的部分或者全部内容的组合可以理解为联合指示，即通过一个索引可以指示配置信息中的多项内容，从而尽量减少MIB中所需指示bit域长度。
而上述索引所述配置信息中部分或者全部内容中的各项内容可以是，为每项内容均配置一个索引，例如资源集合(CORESET)大小、位置、CCE-to-REG的映射关系、PDCCH-to-CCE的映射关系、common PDCCH的传输周期和相对于SS block的QCL信息等均可以通过单独的索引指示。
在一些可选的实施例中，CORESET的大小可以是协议定义好的一个子集(例如配置1的CORESET占据N1个PRB，M1个OFDM符号；例如配置2 的CORESET占据N2个PRB，M2个OFDM符号)，CORESET的位置可以是相对于SS block的一个位置(例如时域上相隔P个OFDM符号，频域上相隔Q个PRB。CORESET相对于SS block可以有多个候选位置)等。
或者CORESET大小集合有A个，CORESET相对于SS block的候选位置有B个，CCE-to-REG的映射规则为集中式(Localized)和分布式(distributed)，PDCCH-to-CCE的映射规则为集中式(Localized)和分布式(distributed)，common PDCCH的传输周期有C个，相对于对应SS block的QCL参数有D个。例如，取A＝2，B＝2，C＝4,D＝4,则公共下行控制信道的参数最后共有2*2*2*2*4*4＝256种组合，则共需要8bit信息在MIB中进行传输。当然，协议可以定义只需要指示全部组合的一个子集。
当然，需要进行联合指示的参数个数并不限于以上6个参数，也可以联合指示其他需要通知的参数，或者只对部分参数联合指示(其他不需要指示的参数通过协议预定义确定)，对此本公开实施例不作限定。
例如：基于上述提供以公共下行控制信道的资源集合(CORESET)以及相关参数通过MIB进行指示进行举例的实例，可以在MIB中指示公共下行控制信道的bit信息应当尽可能少。一种实施方式是采用联合指示多个配置信息的方法进行指示，即指示部分或者全部内容的组合。例如，与公共下行控制信道相关的参数有，公共下行控制信道传输的CORESET资源分配信息，CCE-to-REG映射规则，PDCCH-to-CCE映射规则，公共下行控制信道的周期，即监测周期(monitoring周期)，公共下行控制信道或者公共下行控制信道的CORESET的DMRS相对于对应SS block的QCL参数。可以在协议中引入联合指示表格，并通过指示表格index的方式指示公共下行控制信道的参数配置信息。具体的，假设公共下行控制信道传输的CORESET的资源位置有2种候选位置及大小，CCE-to-REG映射由localized和distributed两种映射规则，PDCCH-to-CCE有localized和distributed两种映射规则，公共下行控制信道的monitoring周期(Common PDCCH occasion periodicity)有4种，例如{每slot，每两个slot，每四个slot，每八个slot}，公共下行控制信道或者CORESET的DMRS相对于对应SS block的QCL参数有2种，则共有2*2*2*4*2＝64种组合共需要6bit信息进行指示。在一些可选的实施例中，如果只需要指示部 分参数，例如CCE-to-REG映射和PDCCH-to-CCE映射规则由协议定义，则只需要4bit指示共16种参数组合，例如表1所示。
例如，当MIB中的公共下行控制信道参数配置指示信息为0000时，指示公共下行控制信道的CORESET为候选位置1，出现的周期为P1，相对于对应SS block的QCL参数为Q1。终端接收到该配置参数后，则在CORESET候选位置1按照P1以及Q1检测接收公共下行控制信道。
又举一个特别的例子，例如通过MIB中的联合指示信息域确定，CORESET的资源配置为候选位置1，检测周期为P1＝2slot，QCL参数为Q1，则公共下行控制信道的传输示意图如图8所示。
在一些可选的实施例中，协议可以选择只定义所有组合中的部分组合组成公共下行控制信道参数联合指示表格。以如上实例(case)为例，假设共有64种组合，但协议规定只需要对其中的部分组合进行指示，例如只需要指示其中的15个组合，则只需要在MIB中携带4bit指示信息进行指示。
表1：
Figure PCTCN2018091065-appb-000001
其中，需要联合指示的公共下行控制信道参数个数可以由协议确定，本 发送实施例并不对具体参数个数以及需要指示的参数数目进行限定。
在一些可选的实施例中，可以仅对部分参数通过表格的形式联合指示，其他参数通过协议定义或者通过其他信息域进行指示。
需要注意的是，MIB可以携带多个CORESET的配置信息，即可以配置多个CORESET用于传输公共下行控制信道。
作为一种可选的实施方式，所述目标信号用于配置所述资源集合的配置信息的部分或者全部内容。
该实施方式中，可以实现通过目标信号直接配置上述资源集合，以提高公共下行控制信道传输的灵活性。另外，上述配置信息可以参见前面实施方式中描述的配置信息，此处不作赘述。且用户终端通过目标信号确定上述配置信息后，可以在上述资源集合内检测接收公共下行控制信道。进一步，可以根据该配置信息确定上述资源集合，并在该资源集合内检测接收公共下行控制信道。
在一些可选的实施例中，所述目标信号包括RMSI、随机接入过程中的消息2或者随机接入过程中的消息4。
该实施方式中，由于可以通过RMSI、随机接入过程中的消息2或者随机接入过程中的消息4配置上述资源集合，这样不需要增加额外的信令，从而节约传输资源。
在一些可选的实施例中，所述资源集合上传输公共下行控制信道使用的波束的相关参数，通过所述资源集合对应的同步接入信号块的QCL参数确定。
该实施方式中，可以实现用户终端通过同步接入信号块的QCL参数确定传输公共下行控制信道使用的波束的相关参数，例如：方向或者波束编号等等，且用户终端可以在与对应SS block传输所使用的相同或者不同波束上检测接收公共下行控制信道，以提高公共下行控制信道传输的灵活性。
需要说明的是，本公开实施例中提供的多种可选的实施方式，可以相互结合实现，也可以单独实现，例如：上述目标信号用于配置所述资源集合的配置信息的部分或者全部内容的实施方式可以与上述目标信号为同步接入信号块的实施方式结合实现，下面以上述目标信号为同步接入信号块的实施方式中的资源集合为第一公共CORESET，而目标信号用于配置所述资源集合的 配置信息的部分或者全部内容的实施方式中资源集合为第二公共CORESET进行举例说明。网络侧设备可以在基于SS block配置的第一公共CORESET基础上配置额外的第二公共CORESET，用于传输公共下行控制信道或者用户终端专用(UE-specific)的下行控制信道。例如：用户终端可以通过RMSI中携带的相关信息获知第二公共CORESET的配置信息。RMSI由在第一公共CORESET传输的公共下行控制信道调度。RMSI配置的第二公共CORESET传输所使用的波束，由RMSI中携带的波束方向参数确定，例如相对于用户终端接收到的SS block的SS参数。网络侧设备可以通过RMSI配置一个或者多个第二公共CORESET。多个第二公共CORESET可以TDM或者FDM，可以采用相同的波束传输也可以采用不同的波束传输。具体的配置信息可以前面实施方式的描述，此处不作赘述。当然，这里仅是以RMSI进行举例，还可以是通过随机接入过程中的Msg2或者Msg4中携带的相关信息获知第二公共CORESET的配置信息，具体流程可以参见RMSI的流程，此处不作赘述。
