Description

小区确定、下行控制信息发送方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及小区确定方法、下行控制信息发送方法、小区确定装置、下行控制信息发送装置、通信装置和计算机可读存储介质。
背景技术
在相关技术中，一个下行控制信息(Downlink Control Information，DCI)只用于调度一个小区的数据，例如调度一个小区的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。
随着频率资源的碎片化，同时调度多个小区的数据的需求逐步提升，为了降低控制消息开销，提出了通过单个DCI调度多个小区的数据，例如用于调度多个小区(数据)的DCI，可以称作MC-DCI，其中，MC表示多小区(multi-cell)或多载波(multi-carrier)。而随着MC-DCI的引入，也随之产生了一些技术问题。
发明内容
有鉴于此，本公开的实施例提出了小区确定方法、下行控制信息发送方法、小区确定装置、下行控制信息发送装置、通信装置和计算机可读存储介质，以解决相关技术中的技术问题。
根据本公开实施例的第一方面，提出一种小区确定方法，由终端执行，所述方法包括：接收用于调度多个小区的下行控制信息MC-DCI；确定所述MC-DCI的相关信息；根据相关信息与至少一个小区之间的关联关系，确定所述MC-DCI的相关信息对应的至少一个小区为所述MC-DCI调度的小区。

为了更清楚地说明本公开实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

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。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。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
在一个实施例中，在引入用于调度多个小区(例如调度3个、4个、8个服务小区的数据)的DCI的情况下，用于调度多个小区的DCI可以称作MC-DCI，其中，MC表示多小区(multi-cell)或多载波(multi-carrier)。本公开所有实施例中描述的调度小区，是指调度小区的数据。
MC-DCI作为新引入的DCI，MC-DCI的格式(format)与传统(legacy)DCI的格式可以不同，legacy DCI包括但不限于用于调度单小区的DCI，例如DCI format 0_0、DCI format 1_0、DCI format 0_1、DCI format 1_1、DCI format 0_2、DCI format 1_2。而MC-DCI可以包括DCI format 0_3、DCI format 1_3。
MC-DCI可以用于调度多个小区，但是目前指示DCI调度小区的方式是通过DCI中的载波指示域(Carrier Indication Field，CIF)进行指示，但是目前的CIF只能指示一个小区，并不适用于指示MC-DCI所调度的多个小区。
图1是根据本公开的实施例示出的一种小区确定方法的示意流程图。本实施例所示的小区确定方法可以由终端执行，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络设备通信，所述网络设备包括但不限于4G、5G、6G等通信系统中的网络设备，例如基站、核心网等。
如图1所示，所述小区确定方法可以包括以下步骤：
在步骤S101中，接收用于调度多个小区的下行控制信息MC-DCI；
在步骤S102中，确定所述MC-DCI的相关信息；
在步骤S103中，根据相关信息与至少一个小区之间的关联关系，确定所述MC-DCI的相关信息对应的至少一个小区为所述MC-DCI调度的小区。
在一个实施例中，终端可以确定网络设备发送的DCI是MC-DCI，还是legacy DCI。在确定网络设备发送的DCI为legacy DCI的情况下，可以不必执行本公开实施例中的步骤，在确定网络设备发送的DCI为MC-DCI的情况下，才执行本公开实施例中的不中。
其中，终端可以根据DCI的格式区分DCI是MC-DCI，还是legacy DCI，也可以通过其他方式区分，例如根据用于接收DCI的资源进行区分，对此，本公开不作限制。
根据本公开的实施例，终端在从网络设备接收到MC-DCI后，可以确定MC-DCI的相关信息，进而根据预先存储的相关信息与至少一个小区(例如小区集合、小区组)之间的关联关系，确定所述MC-DCI的相关信息对应的小区(可以是一个小区，也可以是多个小区)为MC-DCI调度的小区。据此，在MC-DCI调度多个小区的情况下，无需对DCI中的CIF进行调整，也可以使得终端确定MC-DCI所调度的多个小区。
需要说明的是，所述关联关系可以是MC-DCI与多个小区之间的关联关系，也即在MC-DCI用于调度多个小区的情况下，终端才根据所述关联关系确定MC-DCI调度的小区；而为了调度的灵活性，在某些情况下设置MC-DCI用于调度单个小区的时，终端可以选择根据DCI中的CIF确定MC-DCI调度的单个小区，或者根据本实施例中的步骤确定MC-DCI调度的小区。
在一个实施例中，MC-DCI所能调度的小区数量可以根据需要配置，例如可以调度3个、4个或8个小区，以下主要在MC-DCI能够调度4个小区的情况下进行示例性说明。
例如MC-DCI能够调度的4个小区包括cell#1、cell#2、cell#3、cell#4，那么MC-DCI每次调度的小区可以是这4个小区的子集，所述子集包括以下至少之一：

其中，第一RNTI可以是小区无线网络临时标识C-RNTI，第二RNTI可以是其他RNTI，例如新设置的RNTI，可以称作MC-RNTI，MC表示多小区或多载波。
例如终端在接收到MC-DCI后，可以确定用于接收MC-DCI的资源。例如所述关联关系为第一资源对应上述子集中的{cell#1、cell#2、cell#3、cell#4}，第二资源对应上述子集中的{cell#1、cell#2、cell#3}，那么当确定在第一资源接收所述MC-DCI时，可以确定MC-DCI调度的小区包括cell#1、cell#2、cell#3、cell#4，当确定在第二资源接收所述MC-DCI，可以确定MC-DCI调度的小区包括cell#1、cell#2、cell#3。

在步骤S201中，接收用于调度多个小区的下行控制信息MC-DCI；
在步骤S202中，根据网络设备发送的指示信息确定所述MC-DCI调度的小区。
在一个实施例中，终端可以确定网络设备发送的DCI是MC-DCI，还是legacy DCI。在确定网络设备发送的DCI为legacy DCI的情况下，可以不必执行本公开实施例中的步骤，在确定网络设备发送的DCI为MC-DCI的情况下，才执行本公开实施例中的不中。
其中，终端可以根据DCI的格式区分DCI是MC-DCI，还是legacy DCI，也可以通过其他方式区分，例如根据用于接收DCI的资源进行区分，对此，本公开不作限制。
根据本公开的实施例，终端在从网络设备接收到MC-DCI后，可以根据网络设备发送的指示信息(可以在接收到MC-DCI之前或之后接收到，也可以包含在MC-DCI中)确定MC-DCI所调度多个小区，以便采取适当的解析方式正确地解析MC-DCI。据此，在MC-DCI调度多个小区的情况下，无需对DCI中的CIF进行调整，也可以使得终端确定MC-DCI所调度的多个小区。
需要说明的是，终端在预先存储了前文实施例中关联关系的情况下，也可以接收网络设备发送的指示信息，在这种情况下，终端可以优先根据指示信息确定DCI用于调度单个小区或者用于调度多个小区。
在一个实施例中，所述指示信息包括携带在以下至少之一中：
媒体接入控制控制元素MAC CE(Media Access Control Control Element)；
无线资源控制RRC(Radio Resource Control)消息。
网络设备可以在向终端发送MC-DCI之前发送所述指示信息，则终端可以在接收MC-DCI之前接收所述指示信息，例如在接收MC-DCI之前接收RRC消息和/或MAC CE，进而可以根据RRC消息和/或MAC CE中的指示信息确定后续接收到的MC-DCI所调度的多个小区。
在一个实施例中，所述方法还包括：在未正确接收携带所述指示信息的MAC CE的情况下，确定预设的至少一个小区为所述MC-DCI调度的小区，或者在预设小区组合列表中确定预设次序小区组合中的小区为MC-DCI调度的小区。
由于终端在接收MAC CE时，可能存在未正确接收携带所述指示信息的MAC CE的情况(例如未接收到携带指示信息的MAC CE，或者接收到了携带指示信息的MAC CE，但是未能正确解码)，在这种情况下，就不能根据MAC CE中携带的指示信息确定MC-DCI调度哪些小区了。针对这种情况，终端确定预设的一个或多个小区为MC-DCI所调度的小区，或者终端可以预先存储列表，可以称作预设小区组合列表，列表中包含一个或多个小区组合，终端可以在列表中确定预设次序(例如第1个或最后1个)小区组合中的小区为MC-DCI所调度的小区。
在一个实施例中，所述方法还包括：根据协议约定确定所述预设的至少一个小区和/或所述预设小区组合列表；和/或，根据网络设备指示确定所述预设的至少一个小区和/或所述预设小区组合列表。
终端在为正确接收MAC CE的情况下，确定MC-DCI调度的小区所依据的至 少一个预设小区和/或预设小区组合列表，可以是协议约定的，也可以是网络设备指示的，例如网络设备通过其他指示信息向终端指示所述预设的至少一个小区和/或所述预设小区组合列表
图3是根据本公开的实施例示出的一种小区确定方法的应用场景示意图。
如图3所示，在网络设备通过MAC CE携带所述指示信息，向终端指示MC-DCI所调度的多个小区的情况下，终端例如可以在时隙slot#0接收到携带所述指示信息的MAC CE，但是MAC CE中的指示信息可以不是立即生效的，也即可以不用于指示slot#0中的MC-DCI所调度的多个小区。而是在确定正确接收MAC CE后，再等待预设时长(例如可以根据终端的处理能力确定，可以是终端对MAC CE进行解析parsing的耗时)，再用于指示MC-DCI所调度的多个小区。
例如终端在slot#3确定正确接收MAC CE，向网络设备反馈正确接收到的MAC CE的确认信息(ACK)，然后再等待预设时长，例如3毫秒，每个slot对应1毫秒，那么就是从slot#6开始，可以根据slot#0中接收到的MAC CE携带的指示信息确定接收到的MC-DCI所调度的多个小区。
例如MAC CE中指示信息指示的MC-DCI调度的小区为小区组合#2，那么可以从slot#6开始，终端确定接收到的MC-DCI调度的小区为小区组合#2中的小区。而对于在slot#6之前的slot中接收到的MC-DCI，终端可以沿用上一次接收到的指示信息确定MC-DCI所调度的小区，例如上一次接收到的指示信息指示MC-DCI调度的小区为小区组合#1，那么对于在slot#0至slot#5中接收到的MC-DCI，可以确定MC-DCI调度小区为小区组合#1中的小区。
图4是根据本公开的实施例示出的一种下行控制信息发送方法的示意流程图。本实施例所示的下行控制信息发送方法可以由网络设备执行，所述网络设备可以与终端通信，所述网络设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图4所示，所述下行控制信息发送方法可以包括以下步骤：
在步骤S401中，确定用于调度多个小区的下行控制信息MC-DCI调度的小区；
在步骤S402中，根据相关信息与至少一个小区之间的关联关系以及所述MC-DCI调度的小区，设置所述MC-DCI的相关信息；
在步骤S403中，向终端发送所述MC-DCI。
在一个实施例中，网络设备可以确定需要发送至终端的DCI是MC-DCI，还是legacy DCI。在确定需要发送至终端的DCI为legacy DCI的情况下，可以不必执行本公开实施例中的步骤，在确定需要发送至终端的DCI为MC-DCI的情况下，才执行本公开实施例中的不中。
其中，对于MC-DCI和legacy DCI，网络设备可以设置不同的格式以便终端进行区分，当然，终端也可以通过其他方式区分，例如根据用于接收DCI的资源进行区分，对此，本公开不作限制。
根据本公开的实施例，网络在向终端发送MC-DCI的情况下，可以确定MC-DCI所调度的小区，进而根据相关信息与至少一个小区(例如小区集合、小区组)之间的关联关系以及所述MC-DCI调度的小区，设置所述MC-DCI的相关信息(例如为MC-DCI调度的小区在关联关系中对应的相关信息)，以便终端可以根据所述关联关系确定MC-DCI的相关信息对应的小区为MC-DCI所调度的小区。据此，在MC-DCI调度多个小区的情况下，无需对DCI中的CIF进行调整，也可以使得终端确定MC-DCI所调度的多个小区。
在一个实施例中，所述相关信息包括以下至少之一：
用于加扰所述MC-DCI的无线网络临时标识RNTI；
用于接收所述MC-DCI的资源。
网络设备在MC-DCI用于调度不同小区时，可以采用不同的RNTI对MC-DCI进行加扰。例如所述关联关系为第一RNTI对应{cell#1、cell#2、cell#3、cell#4}，第二RNTI对应{cell#1、cell#2、cell#3}，那么当确定需要发送至终端的MC-DCI用于调度cell#1、cell#2、cell#3、cell#4时，可以采用第一RNTI加扰MC-DCI，从而终端在接收到MC-DCI后，可以根据加扰MC-DCI的RNTI为第一RNTI确定MC-DCI用于调度cell#1、cell#2、cell#3、cell#4；当确定需要发送至终端的MC-DCI用于调度cell#1、cell#2、cell#3时，可以采用第二RNTI加扰MC-DCI，从而终端在接收到MC-DCI后，可以根据加扰MC-DCI的RNTI为第二RNTI确定MC-DCI调度cell#1、cell#2、cell#3。
其中，第一RNTI可以是小区无线网络临时标识C-RNTI，第二RNTI可以是其他RNTI，例如新设置的RNTI，可以称作MC-RNTI，MC表示多小区或多载波。
网络设备在MC-DCI用于调度不同小区时，可以采用不同的资源发送MC-DCI。 例如所述关联关系为第一资源对应{cell#1、cell#2、cell#3、cell#4}，第二资源对应{cell#1、cell#2、cell#3}，那么当确定需要发送至终端的MC-DCI用于调度cell#1、cell#2、cell#3、cell#4时，可以采用第一资源发送MC-DCI，从而终端在接收到MC-DCI后，可以根据接收MC-DCI的资源为第一资源确定MC-DCI调度cell#1、cell#2、cell#3、cell#4；当确定需要发送至终端的MC-DCI用于调度cell#1、cell#2、cell#3时，可以采用第二资源发送MC-DCI，从而终端在接收到MC-DCI后，可以根据接收MC-DCI的资源为第二资源确定MC-DCI调度cell#1、cell#2、cell#3。
在一个实施例中，所述资源包括以下至少之一：
小区Cell；
部分带宽BWP；
控制资源集CORESET；
搜索空间SS。
在一个实施例中，所述方法还包括：根据协议约定确定所述关联关系；和/或向所述终端发送指示信息，其中，所述指示信息用于指示所述关联关系。
所述关联关系可以是协议约定的；也可以是网络设备确定，并通过指示信息指示给终端的；还可以是协议约定关联关系的候选集，网络设备通过指示信息在候选集中指示一个关联关系给终端。
图5是根据本公开的实施例示出的一种下行控制信息发送方法的示意流程图。本实施例所示的下行控制信息发送方法可以由网络设备执行，所述网络设备可以与终端通信，所述网络设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图5所示，所述下行控制信息发送方法可以包括以下步骤：
在步骤S501中，向终端发送指示信息，其中，所述指示信息用于指示发送至所述终端的用于调度多个小区下行控制信息MC-DCI调度的小区；
在步骤S502中，向所述终端发送所述MC-DCI。
在一个实施例中，网络设备可以确定需要发送至终端的DCI是MC-DCI，还是legacy DCI。在确定需要发送至终端的DCI为legacy DCI的情况下，可以不必执行本 公开实施例中的步骤，在确定需要发送至终端的DCI为MC-DCI的情况下，才执行本公开实施例中的不中。
其中，对于MC-DCI和legacy DCI，网络设备可以设置不同的格式以便终端进行区分，当然，终端也可以通过其他方式区分，例如根据用于接收DCI的资源进行区分，对此，本公开不作限制。
根据本公开的实施例，网络设备可以向终端发送指示信息(可以在发送MC-DCI之前发送，也可以携带在MC-DCI中发送)，用于指示发送至终端的MC-DCI所调度的小区。终端在从网络设备接收到MC-DCI后，可以根据所述指示信息确定MC-DCI调度哪些小区。据此，在MC-DCI调度多个小区的情况下，无需对DCI中的CIF进行调整，也可以使得终端确定MC-DCI所调度的多个小区。
需要说明的是，在终端预先存储了前文实施例中关联关系的情况下，网络也可以向终端发送指示信息，在这种情况下，终端可以优先根据指示信息确定DCI所调度的小区。
在一个实施例中，所述指示信息包括携带在以下至少之一中：
媒体接入控制控制元素MAC CE；
无线资源控制RRC消息。
网络设备可以在向终端发送MC-DCI之前发送所述指示信息，则终端可以在接收MC-DCI之前接收所述指示信息，例如在接收MC-DCI之前接收RRC消息和/或MAC CE，进而可以根据RRC消息和/或MAC CE携带的指示信息确定后续接收到的MC-DCI是用于调度多个小区还是用于调度单个小区。
在一个实施例中，所述方法还包括：向终端指示预设的至少一个小区和/或预设小区组合列表，其中，所述终端在未正确接收携带所述指示信息的MAC CE的情况下，确定预设的至少一个小区为所述MC-DCI调度的小区，或者在预设小区组合列表中确定预设次序小区组合中的小区为MC-DCI调度的小区。
由于终端在接收MAC CE时，可能存在未正确接收携带所述指示信息的MAC CE的情况(例如未接收到携带指示信息的MAC CE，或者接收到了携带指示信息的MAC CE，但是未能正确解码)，在这种情况下，就不能根据MAC CE中携带的指示信息确定MC-DCI调度哪些小区了。
针对这种情况，网络设备可以向终端指示预设的至少一个小区和/或预设小区组合列表，终端可以根据网络指示确定预设的一个或多个小区为MC-DCI所调度的小区，或者终端可以根据网络指示确定预设小区组合列表，列表中包含一个或多个小区组合，终端可以在列表中确定预设次序(例如第1个或最后1个)小区组合中的小区为MC-DCI所调度的小区。
