技术领域
本发明涉及通信领域，尤其涉及一种服务小区调度方法、终端设备和网络设备。
背景技术
目前，新空口(New Radio，NR)系统支持载波聚合(Carrier Aggregation，CA)，如此可以为用户设备(User Equipment，UE，也可称之为终端设备)配置并激活多个载波(Component Carrier，CC)或小区，且NR系统还支持CA场景下的跨载波调度。
但是，对于NR系统中的一个服务小区而言，其同时仅支持由一个调度小区来调度，具体而言，同一时刻，只能是进行服务小区的自调度或者被另外一个服务小区调度。比如，主服务小区(Primary cell，Pcell)一般仅支持被自己调度，如此，可能会导致Pcell上的物理下行控制信道(Physical Downlink Control Channel，PDCCH)负载较重，从而影响系统性能。

第三方面，本发明实施例提供一种终端设备，包括：存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第一方面所述的方法的步骤。
第四方面，本发明实施例提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现如第一方面所述的方法的步骤。
第五方面，本发明实施例提供一种服务小区调度的方法，应用于网络设备，所述方法包括：配置第一配置信息，所述第一配置信息用于指示第一服务小区支持同时进行自调度和跨载波调度；向终端设备发送所述第一配置信息，所述第一配置信息用于供所述终端设备确定所述第一服务小区进行自调度的第一调度资源和对所述第一服务小区进行跨载波调度的第二调度资源，其中，所述第一调度资源和所述第二调度资源分别包括对应的搜索空间或候选物理下行控制信道(PDCCH)。
第六方面，本发明实施例提供一种网络设备，所述网络设备包括：配置模块，用于配置第一配置信息，所述第一配置信息用于指示第一服务小区支 持同时进行自调度和跨载波调度；发送模块，用于向终端设备发送所述第一配置信息，所述第一配置信息用于供所述终端设备确定所述第一服务小区进行自调度的第一调度资源和对所述第一服务小区进行跨载波调度的第二调度资源，其中，所述第一调度资源和所述第二调度资源分别包括对应的搜索空间或候选物理下行控制信道(PDCCH)。

第八方面，本发明实施例提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现如第五方面所述的方法的步骤。
在本发明实施例中，可以基于来自网络设备的第一配置信息，确定第一服务小区进行自调度所需的第一调度资源以及对该第一服务小区进行跨载波调度所需的第二调度资源，并可以通过该第一配置信息获悉该第一服务小区支持同时进行自调度和跨载波调度(Cross Component Carrier Scheduling)。如此，实现了服务小区在基于包括搜索空间或候选PDCCH的第一调度资源进行自调度的同时，可以基于包括搜索空间或候选PDCCH的第二调度资源对该服务小区进行跨载波调度，达到了提高系统性能的目的，特别是在动态频谱共享场景下。

网络设备，也可称之为基站，可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB)及5G基站(gNB)。
在本发明实施例中，PDCCH传输的物理资源以控制信道元素(Control Channel Element，CCE)为单位，一个CCE的大小为9个资源元素组(Resource Element Group，REG)，即36个资源元素(Resource Element，RE)，一个PDCCH可能占用1、2、4或者8个CCE。对于占用1、2、4、8个CCE的这四种PDCCH大小，可以采用树状的聚合(Aggregation)。
每个聚合级别(Aggregation Level，AL)定义一个搜索空间(Search Space)，包括公共(Common)的搜索空间(CSS)和UE专有(UE-Specific)的搜索空间(USS)。UE在搜索空间内按所处传输模式的下行控制信息(Downlink Control Information，DCI)格式(format)对所有的可能的PDCCH码率进行盲检测。其中，DCIformat0用于指示物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的调度，DCIformat1用于一个物理下行共享信道(Physical Downlink Shared Channel，PDSCH)码字调度的不同模式。
搜索空间是针对每个带宽部分(Bandwidth Part，BWP)进行配置的，一个BWP可配置的最大搜索空间数为10，一个小区(Cell)可配置的最大搜索空间数为40，且一个Cell内配置的搜索空间索引都是唯一的。当某个服务小区(Serving Cell)1配置为被Serving Cell 2调度时，被调度小区(即Serving Cell 1)上激活的BWP配置中没有搜索空间的无线资源控制(Radio Resource Control，RRC)可选域(比如时域监测位置等)的配置，只有搜索空间索引和各聚合级别AL下的盲检候选PDCCH数目的配置。调度小区(即Serving Cell 2)激活BWP上配置的搜索空间中，与被调度小区上激活BWP配置的搜索空间索引相同的搜索空间作为跨载波调度(Cross Component Carrier Scheduling)的搜索空间。
以下结合附图，详细说明本发明各实施例提供的技术方案。
参见图1所示，本发明实施例提供一种服务小区调度方法，由终端设备执行，方法包括以下流程步骤。
步骤101：接收网络设备发送的第一配置信息，第一配置信息用于指示第一服务小区支持同时进行自调度和跨载波调度。
步骤103：根据第一配置信息，确定第一服务小区进行自调度的第一调度资源和对第一服务小区进行跨载波调度的第二调度资源，第一调度资源和第二调度资源分别包括对应的搜索空间或候选物理下行控制信道(PDCCH)。
在本发明实施例中，可以基于来自网络设备的第一配置信息，确定第一服务小区进行自调度所需的第一调度资源以及对该第一服务小区进行跨载波调度所需的第二调度资源，并可以通过该第一配置信息获悉该第一服务小区支持同时进行自调度和跨载波调度。如此，实现了服务小区在基于包括搜索空间或候选PDCCH的第一调度资源进行自调度的同时，可以基于包括搜索空间或候选PDCCH的第二调度资源对该服务小区进行跨载波调度，达到了提高系统性能的目的，特别是在动态频谱共享场景下。
可选的，在本发明实施例的服务小区调度方法中，可以在基于上述第一调度资源在第一服务小区进行自调度的同时，允许第二服务小区(即调度小区)基于第二调度资源对第一服务小区(即被调度小区)进行跨载波调度。
可选的，在本发明实施例的服务小区调度方法中，上述第一调度资源可以包括以下(1)-(4)至少一项。
(1)第一服务小区内通过激活的带宽部分BWP配置的第一类型的搜索空间。也就是说，该第一类型的搜索空间可以为第一服务小区进行自调度的搜索空间，以明确搜索空间类型。其中，该第一类型的搜索空间包括CSS。
(2)第一服务小区内激活的BWP对应的搜索空间中显式的标识为自调度的搜索空间。也就是说，在第一服务小区内激活的BWP对应的搜索空间中有一个或一些搜索空间的配置被标识为可以进行自调度的搜索空间。
(3)第一服务小区内激活的BWP对应的搜索空间中隐式的标识为自调度的搜索空间。也就是说，在第一服务小区内激活的BWP对应的搜索空间中有一个或一些搜索空间的配置被隐式的标识为可以进行自调度的搜索空间。比如，该一个或一些搜索空间的配置中包含特定的域(比如用于指示PDCCH监测时刻(monitoring occasion)配置的域)。
(4)第一服务小区内通过激活的BWP配置的用于监测第一对象的搜索空间，第一对象包括第一下行控制信息(DCI)格式、第一无线网络临时标识(Radio Network Temporary Identifier，RNTI)和第一时域位置中的至少一项。
其中，上述第一DCI格式、第一RNTI和第一时域位置中的至少一项与候选PDCCH相关。该第一DCI格式可以包括DCI format 0_1或DCI format 1_1，第一RNTI可以包括系统信息RNTI(System Information RNTI，SI-RNTI)或配置调度RNTI(Configured Scheduling RNTI，CS-RNTI)等。
可选的，在本发明实施例的服务小区调度方法中，上述第一配置信息还可以包括第一服务小区进行自调度的其他相关信息。其中，该第一服务小区进行自调度的其他相关信息可以包括：下行控制信息格式(比如DCI Format0_1或DCI Format 1_1)中的载波指示域(Carrier Indicator Field，CIF)值。
可选的，在本发明实施例的服务小区调度方法中，上述第一配置信息还可以包括对第一服务小区进行跨载波调度的其他相关信息，其中，该对第一服务小区进行跨载波调度的其他相关信息至少可以包括：第二服务小区的小区标识(Identifier，ID)和第一服务小区在第二服务小区上进行调度的CIF值。
可选的，上述CIF用来确定监测到的PDCCH是哪一个分量载波的PDCCH。
可选的，在本发明实施例的服务小区调度方法中，在上述第一服务小区 为主服务小区(Pcell)的情况下，辅服务小区(Scell)可以作为其调度小区(即上述第二服务小区)；在上述第一服务小区为一个辅服务小区的情况下，主服务小区或另一个辅服务小区可以作为其调度小区(即上述第二服务小区)。
需要说明的是，当第一服务小区为主服务小区，且该主服务小区支持同时进行自调度和跨载波调度时，能够有效减少Pcell上的PDCCH负载，尤其在动态频谱共享场景下能够较大的提高系统性能。
可选的，在本发明实施例的服务小区调度方法中，当基于上述第一配置信息指示第一服务小区支持同时进行自调度和跨载波调度时，这里的指示可以是显式的指示也可以是隐式的指示，即网络设备可以通过该第一配置信息将第一服务小区支持同时进行自调度和跨载波调度显式的指示给终端设备，或者网络设备可以通过该第一配置信息将第一服务小区支持同时进行自调度和跨载波调度隐式的指示给终端设备。
可选的，在本发明实施例的一个具体实施例中，在上述第一服务小区为主服务小区的情况下，上述第一配置信息包括第一配置项，第一服务小区支持同时进行自调度和跨载波调度被网络设备通过第一配置项隐式的指示给终端设备。
可以理解，在主服务小区被配置为支持同时进行自调度和跨载波调度时，可以由网络设备通过第一配置信息隐式的指示给终端设备。在一个示例中，通过第一配置信息中的第一配置项进行隐式的指示，其中，该第一配置项包括但不限于other项。
可选的，在该具体实施例中，上述第一配置项可以用于指示第一服务小区进行自调度的其他相关信息。
在一个示例中，第一服务小区为Pcell且可以通过对应的配置信息(相当于第一配置信息)指示该Pcell可以同时进行自调度和跨载波调度，即Pcell在进行自调度的同时，由Scell(即第二服务小区)对其进行跨载波调度，其中，该配置信息还可以指示调度该Pcell的ScellID和该Pcell在该Scell上进 行调度的CIF值。
可选的，在对Pcell进行配置时，可以通过配置信息中某一配置项(比如other配置项，即第一配置项)隐式的指示联合自调度和跨载波调度；或者通过配置信息中新增的域(即第二配置项)(显式的)指示联合自调度和跨载波调度(即指示该Pcell同时支持进行自调度和跨载波调度)。比如，在调度小区信息(scheduling Cell Info)里增加新的域joint＝own+other；或者在跨载波调度配置(Cross Carrier Scheduling Config)里增加新的域scheduling Cell Info2，当有scheduling Cell Info2配置时，可以联合参考scheduling Cell Info和scheduling Cell Info2，例如scheduling Cell Info配置为own，scheduling Cell Info2配置为other；或者忽略scheduling Cell Info，只参考scheduling Cell Info2，例如scheduling Cell Info2配置为joint(＝own+other)。
在该Pcell激活的BWP上配置的公共搜索空间都为进行自调度的搜索空间，终端设备在Pcell配置的这些搜索空间进行C-RNTI、CS-RNTI(若配置)或调制和编码小区RNTI(Modulation and Coding Scheme Cell RNTI，MCS-C-RNTI)(若配置)加扰的PDCCH盲检DCI 0_0和DCI 1_0来接收数据。对于UE专用搜索空间，此时限制只能配置仅包括搜索空间索引和各聚合级别下的盲检候选PDCCH数目的搜索空间。Scell上激活的BWP配置的搜索空间，并且在Pcell激活的BWP上有与该搜索空间索引相同的UE专有搜索空间的搜索空间可以作为跨载波调度，如图2所示，阴影部分代表完整的搜索空间配置，无阴影部分代表只包含上述搜索空间索引和盲检候选PDCCH数目的搜索空间配置，其中，完整的搜索空间配置是包含所有某些特定域(也可称RRC可选域)的搜索空间配置；否则为非完整的搜索空间配置，例如只包含上述搜索空间索引和盲检候选PDCCH数目的搜索空间配置。可选的，某些特定域用来配置搜索空间的时频监测位置，包括但不限于时域监测周期、时域监测位置和关联的频域控制资源集(Control resource set，CORESET)。
可选的，包含完整配置的UE专用搜索空间默认为自调度的搜索空间，只有仅包括搜索空间索引和各聚合级别下的盲检候选PDCCH数目的搜索空间可以对应跨载波调度搜索空间。Scell上激活的BWP配置的搜索空间，并且在Pcell激活的BWP上有与该搜索空间索引相同的非完整配置的UE专有搜索空间的搜索空间可以作为跨载波调度，如图3所示，阴影部分代表完整的搜索空间配置，无阴影部分代表只包含上述搜索空间索引和盲检候选PDCCH数目的搜索空间配置。
可选的，在上述Pcell上显式的配置为自调度或跨载波调度的搜索空间时，上述图中阴影部分代表用于进行自调度的搜索空间，无阴影部分代表用于进行跨载波调度的搜索空间。
可选的，在本发明实施例的另一个具体实施例中，在上述第一服务小区为主服务小区或辅服务小区的情况下，上述第一配置信息包括第二配置项，第一服务小区支持同时进行自调度和跨载波调度被网络设备通过第二配置项显式的指示给终端设备。
可以理解，在主服务小区或辅服务小区被配置为支持同时进行自调度和跨载波调度时，可以由网络设备通过第一配置信息显示的指示给终端设备。在一个示例中，通过第一配置信息中的第二配置项进行显式的指示，其中，该第二配置项包括但不限于该第一配置信息中新增的指示域。
可选的，在该具体实施例中，上述第二配置项可以用于指示对第一服务小区进行跨载波调度的其他相关信息。
在一个示例中，第一服务小区为Pcell或Scell 1，可以通过对应的配置信息(相当于第一配置信息)指示该Pcell或Scell 1可以同时进行自调度和跨载波调度，即Pcell或Scell 1在进行自调度的同时，由Scell 2(即第二服务小区)对其进行跨载波调度，
可选的，在对Pcell或Scell 1进行配置时，可以通过配置信息显式的指示联合自调度和跨载波调度。在Pcell或者Scell 1内激活的BWP上配置的搜 索空间配置既可以作为自调度搜索空间，又可以作为跨载波调度搜索空间映射配置，并且通过DCI format或者RNTI区分。在该搜索空间可以配置两套盲检候选PDCCH数目或者共用一套相同的盲检候选PDCCH数目配置。如图4所示，USS3配置可以监测DCI 0_0和DCI 1_0，DCI 0_1和DCI 1_1。具体地，在Pcell配置的USS3上进行DCI 0_0和DCI 1_0的监测，在Scell 2配置的USS3上进行DCI 0_1和DCI 1_1的监测。
可选的，在上述Pcell和Scell 2配置USS3的监测时域位置完全重合的情况下，可以一部分监测时域位置用在Scell 2的USS3来跨载波调度Pcell，一部分监测时域位置用在Pcell的USS3来自调度Pcell。
可选的，在本发明实施例的服务小区调度方法中，为了实现第一服务小区进行自调度的同时，还可以对该第一服务小区进行跨载波调度，还包括以下步骤：确定用于调度第一服务小区的第二服务小区。
在一个示例中，上述第一配置信息中包括用于对该第一服务小区进行跨载波调度的第二服务小区的小区ID，进而可以基于该第一配置信息中包含的第二服务小区的小区ID，确定该第二服务小区。需要说明的是，在确定上述第二服务小区时，包括但不限于上述示例中所记载的方案。
可选的，在本发明实施例的服务小区调度方法中，还可以包括：接收网络设备发送的第二服务小区对应的第二配置信息。其中，该第二配置信息包括第二服务小区对应的搜索空间的相关配置信息，包括但不限于搜索空间索引、搜索空间类型、候选PDCCH配置等信息。
进一步可选的，上述步骤103可以包括以下内容：根据第一配置信息和第二配置信息，确定第二调度资源。
可以理解，当第一服务小区支持同时进行自调度和跨载波调度时，为了避免用于自调度和跨载波调度的资源冲突以及顺利实现在第一服务小区进行自调度的同时，可以对该第一服务小区进行跨载波调度，则在确定用于对第一服务小区进行跨载波调度的第二调度资源时，可以综合考虑上述第一配置 信息和第二配置信息。
可选的，在本发明实施例的服务小区调度方法中，上述第二调度资源可以包括以下(1)-(4)至少一项。

(2)第二服务小区内通过激活的BWP配置的第二搜索空间，其中，第一服务小区内激活的BWP上有与第二搜索空间的索引相同且显式的标识为跨载波调度的搜索空间。也就是说，在第二服务小区内激活的BWP对应的搜索空间中有一个或一些搜索空间(即第二搜索空间)的配置被标识为可以进行跨载波调度的搜索空间；同时，需要第一服务小区内激活的BWP上也有与第二搜索空间的索引相同且被显式的标识为进行跨载波调度的搜索空间。
(3)第二服务小区内通过激活的BWP配置的第三搜索空间，其中，第一服务小区内激活的BWP上有与第二搜索空间的索引相同且隐式的标识为跨载波调度的搜索空间。也就是说，在第二服务小区内激活的BWP对应的搜索空间中有一个或一些搜索空间(即第三搜索空间)的配置被隐式的标识为可以进行跨载波调度的搜索空间，比如，该第三搜索空间内仅包含搜索空间索引和各聚合级别下的盲检候选PDCCH数目；同时，需要第一服务小区内激活的BWP上也有与第三搜索空间的索引相同且被隐式的标识为进行跨载波调度的搜索空间。
(4)第二服务小区内通过激活的BWP配置的用于监测第二对象的第四搜索空间，其中，第一服务小区内激活的BWP上有与第四搜索空间索引的相同的搜索空间，第二对象包括第二下行控制信息(DCI)格式、第二无线网络临时标识和第二时域位置中的至少一项。
其中，上述第二DCI格式、第二RNTI和第二时域位置中的至少一项与候选PDCCH相关。该第二DCI格式可以包括DCI format 0_1或DCI format 1_1，第二RNTI可以包括小区RNTI(Cell RNTI，C-RNTI)等。
可选的，在本发明实施例的服务小区调度方法中，在第二服务小区的一个搜索空间包括用于第二服务小区的自调度的第一子调度资源和用于对第一服务小区进行调度的第二子调度资源的情况下，第一子调度资源包括基于第一预设规则(或预配置)确定的部分时域监测位置或部分候选PDCCH，第二子调度资源包括基于第二预设规则(或预配置)确定的部分时域监测位置或部分候选PDCCH。比如，当Cell 1可以调度Cell 1和Cell 2时，在Cell 1上配置的搜索空间一部分时域监测位置来进行自调度Cell 1，另一部分时域监测位置来跨载波调度Cell 2。
可以理解，通过明确调度小区的用于对被调度小区进行跨载波调度的调度资源，有助于实现在第一服务小区进行自调度的同时，可以对该第一服务小区进行跨载波调度。
可选的，上述第一预设规则和所述第二预设规则为基于时域监测位置设置的规则，比如自调度和跨载波调度分别对应的时域监测位置的间隔规则。
进一步地，第一预设规则和第二预设规则之间可以具有一定的关联关系，比如对各时域监测位置进行编号，将奇数的时域监测位置用于进行第一服务小区的自调度，以及将偶数的时域监测位置用于对第一服务小区进行跨载波调度，等等。
可选的，上述时域监测位置可以包括时隙(slot)，一个slot内配置的monitoring occasion、周期等。
