技术领域
本公开涉及通信技术领域，特别涉及一种资源调度方法、系统以及网络设备和终端。
背景技术
第五代移动通信技术(5th Generation mobile networks、5th Generation wireless systems或5th-Generation，5G)新空口(New Radio，NR)支持不同频率范围(Frequency Range，FR)的频谱。随着前几代移动通信网络的频谱重耕，对于低频FR1频段，5G NR可用的频谱往往更分散，带宽更窄。对于FR2频段和一些FR1频段，可用频谱可以更宽，因此需要多载波操作。而确保这些分散的频谱或更宽带宽的频谱以更高的频谱效率、功率效率和灵活的方式被利用，则可提供更高的吞吐量和更广的覆盖。
目前NR的调度机制仅支持一个下行控制信息(Downlink Control Information，DCI)对一个小区上的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)进行调度。在进行多个小区上的PDSCH或PUSCH调度时，各小区都发送各自小区的调度DCI，调度多个小区上的PDSCH或PUSCH需发送多个DCI。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本公开及其应用或使用的任何限制。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
发明人发现：现有的PDSCH或PUSCH的调度方法，导致开销过大。尤其针对5G频段的特点，无法充分利用频谱资源，导致频谱效率、功率效率等较低。
本公开所要解决的一个技术问题是：提出一种新的PDSCH或PUSCH的调度方法，提高频谱资源利用率、频谱效率等，减少开销。
本公开提出一种资源调度方法，下面结合图1～3进行描述。
图1为本公开资源调度方法一些实施例的流程图。如图1所示，该实施例的方法包括：步骤S102～S104。
在步骤S102中，网络设备向终端发送DCI，相应的，终端接收网络设备发送的DCI。
网络设备例如为基站。DCI(可以称为多小区调度DCI)例如包括多个小区的PDSCH或PUSCH的控制信息，该DCI用于调度多个小区中部分或全部小区的PDSCH或PUSCH。在网络设备对PDSCH进行调度的情况下，该DCI用于调度多个小区中部分或全部小区的PDSCH，在网络设备对PUSCH进行调度的情况下，该DCI用于调度多个小区中部分或全部小区的PUSCH。多个小区可以包含同一频带的小区，也可以包含不同频带的小区，可以在每个小区调度一个PDSCH或PUSCH。
需要说明的是，本公开中的DCI可以用于调度多个载波中部分或全部载波的PDSCH或PUSCH，可以在每个载波调度一个PDSCH或PUSCH，将本公开中小区可以全部替换为载波，不影响方案的应用，并且属于本公开的保护范围，在此不再赘述。
一个小区的上行载波可以包括增补上行(Supplementary Uplink，SUL)载波和正常上行(Normal Uplink，NUL)载波。针对每个小区，DCI可以用于调度并指示该小区的PUSCH在SUL载波或者NUL载波上传输。DCI还可以用于调度并指示该小区的PUSCH在SUL载波和NUL载波上同时传输。
在一些实施例中，多个小区的PDSCH或PUSCH的控制信息包括：多个小区的公共控制信息和与多个小区中各个小区对应的专有控制信息。多个小区的公共控制信息对于调度各个小区上的PDSCH或PUSCH取值都相同。多个小区的公共控制信息可以对于各个小区上的PDSCH或PUSCH指示相同的信息，或者对于各个小区上的PDSCH或PUSCH的不相同的信息进行联合指示。各个小区对应的专有控制信息包括调度各个小区上的PDSCH或PUSCH专有的控制信息。各个小区对应的专有控制信息对于调度各个小区的PDSCH或PUSCH取值可不相同。
在一些实施例中，针对多个小区中的每个小区，在DCI不调度该小区的PDSCH或PUSCH的情况下，公共控制信息对该小区指示无效的控制信息，和/或，该小区对应的专有控制信息指示无效的控制信息。在DCI用于调度多个小区中部分小区的PDSCH或PUSCH的情况下，有一部分小区的PDSCH或PUSCH不被DCI调度，对于这些不被调度的小区的PDSCH或PUSCH，公共控制信息指示无效的控制信息，和/或，对应的专有控制信息指示无效的控制信息。
DCI中可以针对某个小区上的PDSCH或PUSCH指示无效的控制信息，表示不对该个小区上的PDSCH或PUSCH进行调度。例如，与该小区对应的专有控制信息的全部或者部分比特指示无效的控制信息，表示不对该个小区上的PDSCH或PUSCH进行调度。专有控制信息指示无效的控制信息例如将全部或者部分比特设置为预设值。例如，该小区对应的专有控制信息中用于指示频域资源分配(FDRA，Frequency Domain Resource Allocation)、调制编码方式、混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)进程数一种或多种的比特全部置0或1。又例如，在多个小区的公共控制信息对于各个小区上的PDSCH或PUSCH的不相同的信息进行联合指示的情况下，可对该小区上的PDSCH或PUSCH指示无效的控制信息。
多个小区的公共控制信息对于各个小区上的PDSCH或PUSCH的不相同的信息进行联合指示的一些实施例如表1所示。针对每个小区，可以预先定义多个小区的公共控制信息的取值与所指示的各个小区上的PDSCH或PUSCH的控制信息映射关系。例如，公共控制信息在取值为3时，针对小区1指示的是第一控制信息，针对小区2指示的是第二控制信息，针对小区3指示的是第一控制信息。又例如，公共控制信息在取值为5时，针对小区1指示的是无效控制信息……
表1

通过以上实施例，DCI的比特数不随调度的小区个数而改变，具有较低的终端检测复杂度。
多个小区的公共控制信息可以包括一种或多种信息，每种信息占用一个域。例如，多个小区的公共控制信息包括：DCI格式识别符、下行链路分配索引、调度的物理上行控制信道(Physical Uplink Control Channel，PUCCH)的功率控制命令、PUCCH资源指示器、PDSCH到HARQ的反馈定时指示器中至少一种信息，不限于所举示例。
各个小区对应的专有控制信息可以包括一种或多种信息，每种信息占用一个域。例如，各个小区对应的专有控制信息包括：带宽部分(Bandwidth Part，BWP)指示器、调制编码方式、新数据指示器、冗余版本、HARQ进程数中至少一种信息，不限于所举示例。
例如，DCI中包括：DCI格式标识符、频域资源分配、时域资源分配、调制编码方式、新数据指示器、冗余版本、下行链路分配索引、调度的PUCCH的功率控制命令、PUCCH资源指示器、PDSCH到HARQ的反馈定时指示器等域，不限于所举示例。DCI包含的域可以参考现有标准，本公开的DCI可以不包括载波指示器(Carrier indicator)域。多个小区的公共控制信息包括的一种或多种信息，各个小区对应的专有控制信息包括的一种或多种信息，每种信息在DCI中分别占用对应的一个域。例如，多个小区的公共控制信息中DCI格式识别符占用DCI中DCI格式标识符域，各个小区对应的专有控制信息中的调制编码方式占用DCI中的调制编码方式域。
下面结合图2A～2C描述多个小区的公共控制信息和各个小区对应的专有控制信息在DCI中位置排布。
在一些实施例中，同一小区对应的专有控制信息占用的比特位置连续；不同小区对应的专有控制信息占用的比特位置在DCI中按照预设顺序排列。
如图2A所示，同一个小区对应的专有控制信息占用不同的域的比特相连续。例如，小区1对应的专有控制信息包括分别占用域1、域2和域3的三种信息，这三种信息在DCI中占用的比特位置连续，同样的，小区2对应的分别占用域1、域2和域3的三种信息在DCI中占用的比特位置也是连续的……如图2A中，省略号表示小区1对应的专有控制信息和小区2对应的专有控制信息之间可以存在其它的比特，也可以不存在其它的比特。
在另一些实施例中，每个小区对应的专有控制信息包括一种或多种信息，每种信息占用一个域；占用同一域的不同小区对应的信息占用的比特位置连续并且按照预设顺序排列。
如图2B所示，占用同一域的不同小区对应的信息占用的比特位置连续。例如，小区1、小区2和小区3对应的占用域1的信息的比特位置连续，小区1、小区2和小区3对应的占用域2的信息的比特位置连续……如图2B所示，省略号表示域1和域2之间可以存在其它的比特，也可以不存在其它的比特。
在一些实施例中，预设顺序为在DCI中由低比特位置到高比特位置按照各个小区的小区索引递增或递减的顺序。小区索引例如为各个小区的服务小区索引(ServCellIndex)。如果小区的上行载波配置了SUL载波和NUL载波，针对DCI调度小区的PUSCH在SUL载波和NUL载波上同时传输的实施方式中，SUL和NUL载波ServCellIndex相同，SUL载波和NUL载波对应的专有控制信息按照先NUL后SUL，或者先SUL后NUL的顺序排布。占用同一域的SUL载波和NUL载波对应的信息，按照先NUL后SUL，或者先SUL后NUL的顺序排布。
如2A所示，各个小区的小区索引例如为1、2、3，不同小区对应的专有控制信息，在DCI中由低比特位置到高比特位置按照各个小区的小区索引递增的顺序排布。如图2B所示，占用同一域的不同小区对应的信息，在DCI中由低比特位置到高比特位置按照各个小区的小区索引递增的顺序排布。
在另一些实施例中，在网络设备向终端发送的无线资源控制(Radio Resource Control，RRC)信息元素中包括：各个小区对应的专有控制信息的比特位置索引；预 设顺序为在DCI中由低比特位置到高比特位置，按照各个小区对应的专有控制信息的比特位置索引递增或递减的顺序。RRC信息元素中还可以配置各个小区的专有控制信息的比特位置索引。例如，在RRC信息元素中的服务小区配置信息元素中的MultiCellSchedulingConfig(多小区调度配置)信元中配置服务小区配置信息元素对应的小区的专有控制信息的比特位置索引。
在一些实施例中，多个小区的公共控制信息占用DCI中连续的比特位置；各个小区对应的专有控制信息占用DCI中连续的比特位置；多个小区的公共控制信息占用的比特位置相对于各个小区对应的专有控制信息占用的比特位置更低。如图2C所示，多个小区的公共控制信息如果占用多个域，该多个域的比特连续。各个小区对应的专有控制信息的所有比特可以是连续的比特。多个小区的公共控制信息可以在DCI的所有比特中占用低比特位置。
在一些实施例中，多个小区的公共控制信息和各个小区对应的专有控制信息占用DCI中多个域，多个域包括比特个数固定的第一域，以及比特个数由多个小区的配置信息确定的第二域；在DCI的所有域中，第一域占用的比特位置相对于第二域占用的比特位置更低。
如图2C所示，多小区公共控制信息占用的域、域1和域2的比特个数固定，与小区的配置信息无关，可以相对于比特数由小区的配置信息确定的域3排布在更低的比特位置。由于各个小区对应的专有控制信息中某一种或多种信息占用比特个数可能与对应的小区的配置信息相关，例如，频域资源分配域的比特个数与该小区的激活BWP的带宽相关。多个小区的公共控制信息中某一种或多种信息占用比特个数可能与多个小区的配置信息相关，例如，多个小区的公共控制信息中BWP指示器的比特对各个小区上的将被激活的BWP进行联合指示，比特个数则与各小区配置的BWP的个数相关。采用上述排布方式，第一域在DCI中的比特位置固定，即比特位置不随调度小区的不同情况而改变，从而终端可以快速解读这些信息。
在步骤S104中，网络设备在部分或全部小区向终端发送PDSCH或接收终端发送的PUSCH，相应的，终端根据DCI，在部分或全部小区接收网络设备发送的PDSCH或向网络设备发送PUSCH。
上述实施例的方案中网络设备向终端发送的DCI中包括多个小区的PDSCH或PUSCH的控制信息，可以根据实际需求调度多个小区中部分或全部小区的PDSCH或PUSCH，终端接收到网络设备发送的DCI后则可以获知在哪些小区接收PDSCH或发 送PUSCH，从而实现网络设备与终端之间的数据传输。上述实施例的方案可以实现通过单个DCI调度多个小区的PDSCH或PUSCH，可以解决低频或中频有多个分散频段的小带宽载波时，如何充分利用频谱资源的问题，降低控制信道的开销，降低控制信道碰撞概率，提升吞吐量，减少终端功率消耗，从而有效提升离散频谱或更宽带宽的频谱的调度灵活性和频谱效率、功率效率等。
下面结合图3描述本公开资源调度方法的另一些实施例。
图3为本公开资源调度方法另一些实施例的流程图。如图1所示，该实施例的方法包括：步骤S302～S306。
在步骤S302中，网络设备向终端发送RRC信息元素，相应的，终端接收网络设备发送的RRC信息元素。
在一些实施例中，RRC信息元素包括指示能够被DCI调度的PDSCH或PUSCH所在的多个小区的信息。DCI中包括的多个小区的控制信息，与RRC信息元素中指示的能够被DCI调度的PDSCH或PUSCH所在的多个小区是对应的。利用DCI可以对RRC信息元素指示的多个小区(2个或者大于2个)中的全部或部分小区上的PDSCH或PUSCH进行调度。
在另一些实施例中，RRC信息元素包括指示传输DCI的小区的信息，用于指示终端在传输DCI的小区接收DCI。
RRC信息元素可以配置哪些小区上的PDSCH或PUSCH能够被DCI调度，即DCI可调度的小区的最大数目和小区的信息。例如，可以增加MultiCellSchedulingConfig信息元素。MultiCarrierSchedulingConfig例如包含在ServingCellConfig(服务小区配置)信息元素中。在MultiCellSchedulingConfig中包括第一指示信息，第一指示信息用于指示ServingCellConfig信息元素对应的小区中的PDSCH或PUSCH能够被DCI调度。例如，RRC信息元素最多可配置3个或者5个小区可以被多小区调度DCI调度小区上的PDSCH或PUSCH。
在一些实施例中，RRC信息元素中服务小区配置信息元素中包括第一指示信息，第一指示信息用于指示服务小区配置信息元素对应的小区中的PDSCH或PUSCH能够被DCI调度。
例如，可以在能够被DCI调度的PDSCH或PUSCH所在小区对应的服务小区配置信息元素增加1bit的第一指示信息，用于指示该小区的PDSCH或PUSCH能够被DCI调度。或者，每个小区对应的服务小区配置信息元素增加预设比特(例如，1bit) 的第一指示信息，当第一指示信息取值为第一值(例如，1)时，表示该小区的PDSCH或PUSCH能够被DCI调度，当第一指示信息取值为第二值(例如，0)时，表示该小区的PDSCH或PUSCH不能够被DCI调度。当然，也可以直接在RRC中直接指示能够被DCI调度的PDSCH或PUSCH所在小区的小区索引，指示方法不限于所举示例。
在一些实施例中，在RRC信息元素中的服务小区配置信息元素中包括第二指示信息，第二指示信息用于指示在服务小区配置信息元素对应的小区传输DCI，或者第二指示信息用于指示调度服务小区配置信息元素对应的小区的PDSCH或PUSCH的DCI所在的小区。
例如，可以在传输DCI的小区对应的服务小区配置信息元素增加1bit的第二指示信息，用于指示该小区用于传输DCI。或者，每个小区对应的服务小区配置信息元素增加预设比特(例如，1bit)的第二指示信息，当第二指示信息取值为第三值(例如，1)时，表示该小区用于传输DCI，当第二指示信息取值为第四值(例如，0)时，表示该小区不用于DCI调度。或者，每个小区或能够被DCI调度的PDSCH或PUSCH所在小区对应的服务小区配置信息元素增加第二指示信息，指示传输DCI的小区索引。例如在MultiCellSchedulingConfig中包括第二指示信息。例如，若在服务小区配置信息元素中包括第二指示信息，默认服务小区配置信息元素对应的小区的PDSCH或PUSCH能够被DCI调度，从而无需在服务小区配置信息元素中包括第一指示信息。指示方法可以根据实际需求设置，不限于所举示例。
在步骤S304中，网络设备向终端发送DCI，相应的，终端接收网络设备发送的DCI。
在步骤S306中，网络设备在DCI调度的小区向终端发送PDSCH或接收终端发送的PUSCH，相应的，终端在DCI调度的小区接收网络设备发送的PDSCH，或向网络设备发送PUSCH。
步骤S304～S306可以参考步骤S102～S104，在此不再赘述。
上述实施例通过RRC信息元素可以动态指示能够被DCI调度的多个小区和传输DCI的小区，实现能够被DCI调度的多个小区和DCI的灵活配置，平衡多小区的DCI负载。
