Description

下行控制信息识别、配置方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及下行控制信息识别方法、下行控制信息配置方法、下行控制信息识别装置、下行控制信息配置装置、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，DCI中可以包含MC-DCI，也可以包含传统(legacy)DCI，而MC-DCI与传统DCI不同，因此，如何区分MC-DCI和传统DCI是亟待解决的技术问题。
发明内容
有鉴于此，本公开的实施例提出了下行控制信息识别方法、下行控制信息配置方法、下行控制信息识别装置、下行控制信息配置装置、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。

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。
MC-DCI作为新引入的DCI，MC-DCI的格式(format)与传统(legacy)DCI的格式(format)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的格式可以为新配置的格式，例如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，legacy DCI则用于调度单个小区，所以这两种DCI的功能是不同的，这两种DCI中信息域的含义也是不同的，例如MC-DCI中一个类型的信息域可以指示多个小区的调度信息，而legacy DCI中一个类型的信息域则只能指示一个小区的调度信息。由于这两种DCI中信息域的含义不同，解析这两种DCI的解析方式也就会存在差异，所以需要使得终端能够确定DCI是MC-DCI，还是legacy DCI，以便采取对应的解析方式正确地解析DCI。
图1是根据本公开的实施例示出的一种下行控制信息识别方法的示意流程图。本实施例所示的下行控制信息识别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，所述下行控制信息识别方法可以包括以下步骤：
在步骤S101中，确定下行控制信息DCI的相关信息；
在步骤S102中，根据所述DCI的相关信息识别所述DCI的类型，其中，所述类型为用于调度多个小区数据的MC-DCI或传统legacy DCI。
根据本公开的实施例，终端在从网络设备接收到DCI后，可以确定DCI的相关信息，进而根据预先存储(例如可以是根据协议约定确定的或者根据网络发送的信令确定的)的相关信息与DCI的类型之间的关联关系，确定接收到的DCI的相关信息对应的DCI的类型，也即确定所述DCI是用于调度多个小区的MC-DCI，还是legacy DCI，以便采取适当的解析方式正确地解析DCI。
需要说明书的是，本公开的实施例主要用于MC-DCI和legacy DCI的区分，而关于legacy DCI中不同DCI的区分，可以根据DCI的尺寸(size，也即占用的比特数)或信令进行区分。
例如，DCI format 0_3表示调度多小区上行的MC-DCI，DCI format 1_3表示调度多小区下行的MC-DCI，DCI format 0_1表示调度单小区上行的MC-DCI，DCI format1_1表示调度单小区下行的MC-DCI。本公开的实施例可以用于区分DCI format 0_3和DCI format 0_1，也可以用于区分DCI format 1_3和DCI format 1_1。而关于legacy DCI中DCI format 0_1和DCI format 0_2的区分，则可以根据DCI的尺寸或信令进行区分。关于DCI format 0_3和DCI format 1_3区分，以及DCI format 0_1和DCI format1_1的区分，可以根据DCI中的信息域的值确定。
在一个实施例中，所述相关信息包括以下之一：
用于接收所述DCI的资源的信息；
用于加扰所述DCI的无线网络临时标识RNTI(Radio Network Temporary Identity)；
用于指示所述DCI为MC-DCI或legacy DCI的指示信息。
在一个实施例中，所述根据所述DCI的相关信息识别所述DCI的类型包括：在所述DCI的相关信息为第一相关信息的情况下，确定所述DCI为MC-DCI；和/或在所述DCI的相关信息为第二相关信息的情况下，确定所述DCI为legacy DCI。
在一个实施例中，终端在接收到DCI后，可以确定用于加扰DCI的RNTI。例如相关信息与DCI的类型之间的关联关系为第一RNTI对应legacy DCI，第二RNTI对应MC-DCI，那么当确定用于加扰DCI的RNTI为第一RNTI时，可以确定接收到的DCI为legacy DCI，当确定用于加扰DCI的RNTI为第二RNTI时，可以确定接收到的DCI为MC-DCI。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，或者称作MCS-SC-RNTI，MCS表示多载波调度(Multi-carrier scheduling)，SC表示调度小区(scheduling cell)。
图2是根据本公开的实施例示出的一种下行控制信息识别方法的应用示意图。如图2所示，例如以Cell#0、Cell#1和Cell#2这3个小区为例，终端在Cell#0上接收到DCI后，可以确定用于加扰DCI的RNTI。
在确定加扰DCI的RNTI为MCS-SC-RNTI时，可以确定DCI用于调度多个小区，例如调度Cell#0、Cell#1和Cell#2这3个小区(例如调度PDSCH)。在确定加扰DCI的RNTI为C-RNTI时，可以确定DCI用于调度单个小区，例如调度Cell#1。
在一个实施例中，终端可以接收用于指示所述DCI为MC-DCI或legacy DCI的指示信息，其中，所述指示信息包括但不限于无线资源控制(Radio Resource Control，RRC)信令，所述DCI中优先解析的信息域等。终端在接收到DCI后，可以根据所述指示信息确定接收到的DCI为MC-DCI还是legacy DCI。
其中，所述指示信息可以占用1比特，或者占用2比特。
在所述指示信息占用1比特的情况下，所述指示信息可以用于区分DCI为MC-DCI还是legacy DCI。例如0表示DCI为legacy DCI，1表示DCI为MC-DCI。
在所述指示信息占用2比特的情况下，所述指示信息可以用于区分DCI为MC-DCI还是legacy DCI，还可以进一步区分DCI用于调度上行，还是用于调度下行。例如00表示DCI为用于调度上行的MC-DCI(e.g.,DCI 0_3)，01表示DCI为用于调度下行的MC-DCI(e.g.,DCI 1_3)，10表示DCI为用于调度上行的legacy DCI(e.g.,DCI0_1)，11表示DCI为用于调度下行的legacy DCI(e.g.,DCI 1_1)。
需要说明的是，相关信息与DCI的类型之间的关联关系，可以是网络设备指示的，也可以是协议约定的，还可以是协议约定关联关系的候选集，进而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。
在一个实施例中，终端在接收到DCI后，可以确定用于接收所述DCI的资源。例如相关信息与DCI的类型之间的关联关系为第一资源对应legacy DCI，第二资源对应MC-DCI，那么当确定在第一资源接收所述DCI时，可以确定接收到的DCI为legacy DCI，当确定在第二资源接收所述DCI，可以确定接收到的DCI为MC-DCI。
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(BandWidth Part)；
搜索空间SS(Search Space)。
以所述资源包括BWP进行示例，例如所述关联关系为第一BWP集合对应legacy DCI，第二BWP集合对应MC-DCI。当确定在BWP#1接收到DCI时，若BWP#1属于第一BWP集合，可以确定接收到的DCI为legacy DCI，当确定在BWP#2接收到DCI时，若BWP#2属于第二BWP集合，可以确定接收到的DCI为MC-DCI。
在一个实施例中，SS的信息包括以下至少之一：
SS的标识；
SS所关联的控制资源集CORESET(Control Resource Set)的标识；
SS中物理下行控制信道(Physical Downlink Control Channel，PDCCH)候选的数目；
SS的监听时隙周期；
SS的时隙的起始位置；
SS的监听时隙数；
SS的时隙内监听符号起始位置。
其中，SS的信息元素(Information Element，IE)包括searchSpaceId(搜索空间标识)、controlResourceSetId(控制资源集标识)、nrofCandidates(多个聚合等级下的PDCCH candidates数目)、monitoringSlotPeriodicityAndOffset(搜索空间配置周期以及对应的时隙偏移)、duration(搜索空间持续时隙数目)、monitoringSymbolsWithinSlot(在时隙范围内，搜索空间关联的CORESET符号起始位置)。

图4是根据本公开的实施例示出的一种下行控制信息配置方法的示意流程图。本实施例所示的下行控制信息配置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，所述下行控制信息配置方法可以包括以下步骤：
在步骤S401中，确定向终端发送的DCI的类型；
在步骤S402中，根据所述类型配置所述DCI的相关信息。
根据本公开的实施例，网络在向终端发送DCI的情况下，可以根据DCI的相关信息与DCI的类型之间的关联关系，设置DCI的相关信息，从而使得终端在从网络设备接收到DCI后，可以根据预先存储(例如可以是根据协议约定确定的或者根据网络发送的信令确定的)的相关信息与DCI的类型之间的关联关系，确定接收到的DCI的相关信息对应的DCI的类型，也即确定所述DCI是用于调度多个小区的MC-DCI，还是legacy DCI，以便采取适当的解析方式正确地解析DCI。
在一个实施例中，所述相关信息包括以下之一：
用于发送DCI的资源的信息；
用于加扰所述DCI的RNTI；
用于指示所述DCI为MC-DCI或legacy DCI的指示信息。
在一个实施例中，所述根据所述DCI的相关信息识别所述DCI的类型包括：在确定所述DCI为MC-DCI的情况下，配置所述DCI的相关信息为第一相关信息；和/或在确定所述DCI为legacy DCI的情况下，配置所述DCI的相关信息为第二相关信息。
在一个实施例中，对于legacy DCI和MC-DCI，网络设备可以采用不同的RNTI进行加扰。例如相关信息与DCI的类型之间的关联关系为第一RNTI对应legacy DCI， 第二RNTI对应MC-DCI，那么当确定需要发送至终端的DCI为legacy DCI时，可以采用第一RNTI加扰DCI，从而终端在接收到DCI后，可以根据加扰DCI的RNTI确定DCI为legacy DCI；当确定需要发送至终端的DCI为MC-DCI时，可以采用第二RNTI加扰DCI，从而终端在接收到MC-DCI后，可以根据加扰DCI的RNTI确定DCI为MC-DCI。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，或者称作MCS-SC-RNTI，MCS表示多载波调度，SC表示调度小区。
在一个实施例中，对于legacy DCI和MC-DCI，网络设备可以向终端发送不同的指示信息，以指示终端发送至终端的DCI为MC-DCI或legacy DCI。其中，所述指示信息包括但不限于无线资源控制信令，所述DCI中优先解析的信息域等。终端在接收到DCI后，可以根据所述指示信息确定接收到的DCI为MC-DCI还是legacy DCI。
其中，所述指示信息可以占用1比特，或者占用2比特。
在所述指示信息占用1比特的情况下，所述指示信息可以用于区分DCI为MC-DCI还是legacy DCI。例如0表示DCI为legacy DCI，1表示DCI为MC-DCI。
在所述指示信息占用2比特的情况下，所述指示信息可以用于区分DCI为MC-DCI还是legacy DCI，还可以进一步区分DCI用于调度上行，还是用于调度下行。例如00表示DCI为用于调度上行的MC-DCI，01表示DCI为用于调度下行的MC-DCI，10表示DCI为用于调度上行的legacy DCI，11表示DCI为用于调度下行的legacy DCI。
在一个实施例中，对于legacy DCI和MC-DCI，网络设备可以采用不同的资源发送。例如相关信息与DCI的类型之间的关联关系为第一资源对应legacy DCI，第二资源对应MC-DCI，那么当确定需要发送至终端的DCI为legacy DCI时，可以采用第一资源发送DCI，从而终端在接收到DCI后，可以根据用于接收DCI的资源DCI为legacy DCI；当确定需要发送至终端的DCI为MC-DCI时，可以采用第二资源发送DCI，从而终端在接收到DCI后，可以根据用于接收DCI的资源DCI为MC-DCI。
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；
搜索空间SS。
以所述资源包括BWP进行示例，例如所述关联关系为第一BWP集合对应legacy DCI，第二BWP集合对应MC-DCI。当需要向终端发送legacy DCI时，可以选择在属于第一BWP集合的BWP#1向终端发送DCI，终端确定在BWP#1接收到DCI时，可以确定接收到的DCI为legacy DCI；当需要向终端发送MC-DCI时，可以选择在属于第二BWP集合的BWP#2向终端发送DCI，终端确定在BWP#2接收到DCI时，可以确定接收到的DCI为MC-DCI。
在一个实施例中，SS的信息包括以下至少之一：
SS的标识；
SS所关联的控制资源集CORESET的标识；
SS中物理下行控制信道候选的数目；
SS的监听时隙周期；
SS的时隙的起始位置；
SS的监听时隙数；
SS的时隙内监听符号起始位置。
其中，SS的信息元素(Information Element，IE)包括searchSpaceId(搜索空间标识)、controlResourceSetId(控制资源集标识)、nrofCandidates(多个聚合等级下的PDCCH candidates数目)、monitoringSlotPeriodicityAndOffset(搜索空间配置周期以及对应的时隙偏移)、duration(搜索空间持续时隙数目)、monitoringSymbolsWithinSlot(在时隙范围内，搜索空间关联的CORESET符号起始位置)。
其中，SS的标识可以通过searchSpaceId进行配置；SS所关联的CORESET的标识可以通过controlResourceSetId进行配置；SS中PDCCH候选的数目可以通过nrofCandidates进行配置；SS的监听时隙周期和SS的时隙的起始位置可以通过monitoringSlotPeriodicityAndOffset进行配置；SS的监听时隙数可以通过duration进行配置；SS的时隙内监听符号数可以根据monitoringSymbolsWithinSlot进行配置。
