Description

一种资源调度指示方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种资源调度指示方法及装置。
背景技术
随着无线通信技术的飞速发展，无线通信系统的频谱资源日益稀缺，低频段的频谱已经不能满足日益增长的业务需求，已有越来越多的无线通信系统使用更高频段的频谱进行通信。
在第五代移动通信技术(fifth generation，5G)新无线(new radio，NR)系统中，可以配置多个部分带宽(bandwidth part，BWP)，并在BWP内进行资源调度。在NR系统中进行资源调度时，可以通过下行控制信息(downlink control information，DCI)来指示进行资源调度，但是一个DCI只能调度一个载波上的数据，在载波聚合场景下，如果要调度多个数据，则需要多个DCI才能调度多个载波上的数据，这样会造成信令的浪费，因此，在带宽较大的场景下，如何降低信令开销是有待解决的问题。
发明内容
本申请提供一种资源调度指示方法及装置，用于降低信令开销，提高数据传输效率。
本申请实施例可以应用于各种移动通信系统，例如：新无线(new radio，NR)系统、长期演进(long term evolution，LTE)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、演进的长期演进(evolved long term evolution，eLTE)系统等其它通信系统，具体的，在此不做限制。
第一方面，本申请提供一种资源调度指示方法，该方法包括：网络设备确定一个控制信息，所述一个控制信息包括不同载波上的多个数据的资源调度指示信息，所述资源调度指示信息用于所述网络设备对所述多个数据进行资源调度；所述网络设备向终端设备发送所述一个控制信息。
通过上述技术方案，在对多个数据进行资源调度时，可以通过单个控制信息调度不同载波上的多个数据，而不需要通过多个控制信息来调度多个数据，这样可降低信令开销，避免信令浪费。

在一种可能的实现中，所述频率资源指示信息中包括第一资源指示值RIV；所述第一RIV用于指示所述多个数据的频域资源的集合；或者所述第一RIV用于指示所述多个数据中的一个数据的频域资源。
通过上述技术方案，可以通过RIV指示多个数据的频域资源位置，例如可以指示多个数据的频域资源的集合，也可以指示多个数据中的一个数据的频域资源，从而使得终端设备能够根据RIV指示确定出多个数据中的每一个数据的频域资源位置。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端，又称之为终端设备、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端可以包括用户设备(user equipment，UE)、无线终端、移动终端、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端的计算机，便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，智能穿戴式设备等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位系统(global positioning system，GPS)、激光扫描器等信息传感设备。
作为示例而非限定，在本申请实施例中，该终端还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。该终端还可以是虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
而如上介绍的各种终端，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端，车载终端例如也称为车载单元(on-board unit，OBU)。本申请实施例中，终端还可以包括中继(relay)。或者理解为，能够与基站进行数据通信的都可以看作终端。
2)网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端通信的设备，或者例如，一种V2X技术中的网络设备为路侧单元(road side unit，RSU)。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。网络设备还可协调对空口的属性管理。例如，网络设备可以包括无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等，也可以包括长期演进(long term evolution，LTE)系统或高级长期演进LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(fifth generation，5G)新无线(new radio，NR)系统中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
3)信道带宽(channel bandwidth)，也称为载波带宽，为基站或者UE的单个射频载波的带宽。
4)配置带宽，即配置的传输带宽，为基站或者UE在某个载波下，可用的带宽大小。通常是除去载波两端边缘的保护频带(guard band)之外的可用带宽的大小。一般用资源块(resource block，RB)的个数表示。
5)传输带宽，也可以称为激活的传输带宽，又或者称为部分带宽(bandwidth part，BWP)。参阅图1所示，为本申请实施例提供的一种带宽示意图。在图1中示意出了信道带宽、配置带宽、传输带宽(active resource blocks)。需要说明的是，实际的传输带宽通常小于或等于配置带宽。
BWP的配置通过定义一个起始索引RB start和RB的个数L RB来指示BWP对应的频域资源位置和带宽大小。在NR系统中，资源调度是以定义在BWP内的物理资源块(physical resource blocks，PRB)为基本单元实现的。
其中，PRB是按照某种子载波间隔的配置定义在一个BWP内的资源块，PRB的编号为0到
Figure PCTCN2020121677-appb-000001
其中，i是BWP的编号，
Figure PCTCN2020121677-appb-000002
表示BWP i所包含的PRB的个数，μ为子载波间隔配置。
6)载波组，将多个载波聚合在一起形成载波组。在一个载波组内，BWP可以灵活配置，一个BWP可以包括一个或多个载波的部分资源块或者全部资源块。如图2所示，假设载波1、载波2和载波3为一个载波组，这三个载波可以聚合成一个超大带宽。示例性的，假设每个载波的带宽为100MHz，则三个载波聚合可以实现300MHz的带宽。当然， 可以理解的是，聚合的多个载波中每个载波的带宽可以相同，也可以不同。示例性的，图2中包括BWP1、BWP2，其中，BWP1包括载波1的部分资源块和载波2的全部资源块。BWP2包括载波1的部分资源块、载波2的全部资源块以及载波3的部分资源块。
可选的，载波组内聚合的多个载波的资源栅格是对齐的，或者说多个载波基于相同的资源栅格进行资源划分。例如图2所示，待聚合的多个载波的资源块是完全连续排布的。此时，BWP在载波组内可以灵活的配置，一个BWP可以包含一个或多个载波的部分或全部资源块。
7)本申请实施例中“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个，例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C、A和B、A和C、B和C、或A和B和C。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。本申请实施例中的术语“系统”和“网络”可被互换使用。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。
目前，NR系统中在进行资源调度时，可以通过不同的DCI格式来实现。例如，可以通过DCI format 0_0，DCI format 0_1，DCI format 0_2调度物理上行控制信道数据(physical uplink shared channel，PUSCH)；可以通过DCI format 1_0，DCI format 1_1，DCI format 1_2调度物理下行控制信道数据(physical downlink shared channel，PDSCH)。通常，一个DCI只能调度一个数据。并且，一个DCI只能调度一个小区(cell)或者一个载波上的数据。
目前，在进行资源划分时，以载波作为第一基本单元，然后在载波内进一步以BWP作为第二基本单元，最后在BWP内以资源块或资源块组作为第三基本单元进行资源调度指示。一个资源调度指示信息只能调度一个载波或cell上的数据，在载波聚合场景下，如果要调度多个数据，则需要多个资源调度指示信息才能完成资源调度指示，这样会造成信令浪费。
有鉴于此，本申请实施例提供一种资源调度指示方法，通过单个控制信息调度多个数据，从而无需多个资源调度指示信息，可以减少信令开销，避免信令浪费。
本申请实施例提供的技术方案可以应用于5G系统中，例如NR系统中，或者还可以应用于5G下一代移动通信系统或其他类似的通信系统，具体的不做限制。
如图3所示为本申请实施例提供的一种网络架构示意图，参阅图3所示，图3中包括接入网设备和6个终端(UE1～UE6)，图3中的终端的数量只是举例，还可以更少或更多。图3只是示意图，该网络架构中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图3中未画出。
接入网设备是终端通过无线方式接入到该移动通信系统中的接入设备，例如可以是基站NodeB、演进型基站eNodeB、5G通信系统中的基站、未来移动通信系统中的基站或无线保真(wireless-fidelity，Wi-Fi)系统中的接入节点等，本申请的实施例对接入网设备所采用的具体技术和具体设备形态不做限定。
终端，或可被称为终端设备。示例性地，终端可以是蜂窝电话、智能电话、便携式电 脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统上通信的任意其它适合设备，且均可以与接入网设备连接。
接入网设备和终端可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请的实施例对接入网设备和终端的应用场景不做限定。
本申请的实施例可以适用于下行信号传输，也可以适用于上行信号传输。对于下行信号传输，发送设备是接入网设备，对应的接收设备是终端。对于上行信号传输，发送设备是终端，对应的接收设备是接入网设备。当然，本申请实施例还可适用于设备到设备通信(device-to-device，D2D)的信号传输。对于D2D的信号传输，发送设备是终端，对应的接收设备也是终端。例如，如图3中虚线区域包括的3个终端(UE4、UE5以及UE6)可以适用于D2D的信号传输。本申请实施例中对信号的传输方向不做限定。
下面结合附图详细介绍本申请实施例提供的技术方案。
如图4所示，为本申请实施例提供的一种资源调度指示方法流程图，参阅图4所示，该方法包括：
S401：网络设备确定一个控制信息。
S402：网络设备将一个控制信息发送给终端设备。相应的，终端设备接收网络设备发送的一个控制信息。
S403：终端设备根据一个控制信息进行数据发送或数据接收。
可以理解的是，数据发送对应的是上行数据传输，数据接收对应的是下行数据传输。
以下具体对图4所示实施例中的步骤进行详细介绍。
本申请实施例中，控制信息可以为DCI或者侧链控制信息(sidelink control information，SCI)。具体而言，可以通过DCI调度PDSCH或者PUSCH，通过SCI调度PSSCH。可以理解的是，PDSCH对应下行数据，PUSCH对应上行数据，PSSCH对应边链路数据。为了描述方便，以下将PDSCH、PUSCH、PSSCH统称为“数据”。
具体来说，控制信息可以包括不同频域位置上的多个数据的资源调度指示信息，资源调度指示信息可用于网络设备对多个数据进行资源调度。由于在载波聚合场景下包括多个载波，那么该控制信息可包括如下两种情形：
情形1：一个控制信息包括不同载波上的多个数据的资源调度指示信息。也就是说，不同载波上的多个数据为多个载波上的多个数据。示例性的，以图2为例，假设载波1上的数据为数据1，载波2上的数据为数据2，则控制信息可以包括载波1上的数据1和载波2上的数据2的资源调度指示信息。
情形2：一个控制信息包括同一载波上的多个数据的资源调度指示信息。即，多个数据可以为同一载波内的不同频域位置上的多个数据。以图2为例，假设载波1上的数据包括数据1和数据2，并且数据1和数据2位于载波1上的不同频域位置，那么控制信息中可以包括载波1上的数据1和载波1上的数据2的资源调度指示信息。
需要说明的是，多个数据可以分别映射在多个载波内，即每一个数据映射在单个载波内。当然，多个数据也可以跨载波映射在不同的载波内，即一个数据可以映射在两个载波内，本申请对此不做具体限定。
本申请实施例中，资源调度指示信息可以包括以下至少一种信息：不同载波对应的载波组信息、多个数据对应的BWP指示信息、混合自动重传请求(hybrid automatic repeat  request，HARQ)进程信息、传输功率控制指示信息、调制编码方案指示信息、新数据指示信息、信道接入指示信息、时域资源指示信息和频域资源指示信息。
作为一种可能的实现方式，上述资源调度指示信息可以通过控制信息(比如DCI)中的一个或多个字段来表示。
以下对上述所列出的资源调度指示信息进行详细介绍。
(1)、载波组信息
载波组可以为不同载波对应的载波组。示例性的，以图2为例，图2包括载波1、载波2和载波3，例如可以包括如下几种载波组：载波1和载波2组成的载波组1，载波2和载波3组成的载波组2，载波1、载波2和载波3组成的载波组3。
在一种可能的实现中，可以定义字段(例如，carrier group index)来指示调度指示信息用于调度哪个载波组的数据。需要说明的是，该字段可以为新定义的字段，也可以复用已有的字段，本申请不作限定。
示例性的，当该字段的值为“0”时，可以指示调度载波组1的数据，当该字段的值为“1”时，可以指示调度载波组2的数据；或者当该字段的值为“1”时，可以指示调度载波组1的数据，当该字段的值为“2”时，可以指示调度载波组2的数据。可以理解的是，上述仅是一种示例，本申请并不限于此。
(2)、BWP指示信息
由于在进行资源调度时，是基于一个BWP内的载波进行的资源调度，因此，本申请中可以利用BWP指示信息来指示调度指示信息用于调度哪个BWP上的数据。在一种可能的实现中，可以复用目前NR系统的DCI format中的Bandwidth part indicator字段来指示调度哪个BWP上的数据。
示例性的，以图2为例，当Bandwidth part indicator字段的值为“1”时，可以指示调度BWP1上的数据，当Bandwidth part indicator字段的值为“2”时，可以指示调度BWP2上的数据。
(3)、HARQ进程信息
在一些实施例中，HARQ进程信息中可包括第一指示信息，该第一指示信息可用于指示多个数据的HARQ进程标识。
当多个数据的HARQ进程标识相同时，HARQ进程信息中可包括一个第一指示信息。也就是说，如果调度指示信息包括一个HARQ进程标识，则说明所要调度的多个数据的HARQ进程标识相同。
示例性的，可以在控制信息中定义字段(例如，HARQ process number)，假设该字段包括M比特(如M＝4)，该字段的值对应一个HARQ进程标识。如果调度指示信息中仅包括一个字段值4，则说明调度指示信息指示的多个数据的HARQ进程标识相同。
当多个数据的HARQ进程标识不同时，HARQ进程信息中可包括多个指示信息。也就是说，如果调度指示信息中包括多个HARQ进程标识，则说明所要调度的多个数据的HARQ进程标识不同。或者，换句话来说，多个数据中每一个数据可对应一个HARQ进程标识。
示例性的，可以在控制信息中定义字段(例如，HARQ process number)，假设该字段包括M比特，该字段的值对应一个HARQ进程标识。如果调度指示信息中包括多个字段值，则说明调度指示信息指示的多个数据的HARQ进程标识不同。
作为一种可能的实现，假设该字段包括N*M比特，所述N为BWP内包括的载波个数，该字段按照高比特位到低比特为进行排序，然后将每M比特的值对应一个HARQ进程标识。也就是说，如果N＝2，M＝3，那么该字段可包括6比特，每3比特可对应一个HARQ进程标识。
在另一些实施例中，HARQ进程信息中可包括第二指示信息，该第二指示信息可用于指示多个数据中的一个数据的HARQ进程标识。示例性的，可以在控制信息中定义字段(例如，HARQ process number)，假设该字段包括M比特，该字段的值可对应多个数据的第一个数据的HARQ进程标识，那么其它数据的HARQ进程标识可通过第一个数据的HARQ进程标识推算得到。需要说明的是，该字段的值也可以对应多个数据的任意一个数据的HARQ进程标识，那么其它数据的HARQ进程标识也可以通过该字段的值推算得到。
举例来说，假设该字段的值为“1”，即多个数据中的第一个数据的HARQ进程标识为1，那么第二个数据的HARQ进程标识为第一个数据的HARQ进程标识+1，即第二数据的HARQ进程标识为2，以此类推。可以理解的是，多个数据可以在频域上按照从低到高的顺序排序，第一个数据可以为频域上最低位置上的一个数据，当然，还可以按照其他的顺序进行排序，本申请对此不作限定。
(4)、传输功率控制(transmit power control，TPC)指示信息
在一种可能的实施方式中，针对所要调度的多个数据可以采用相同的TPC指示信息。也就是说，控制信息的字段值可以为一个字段值。当然，也可以针对所要调度的多个数据采用不同的TPC指示信息。即，每一个数据可以对应一个TPC指示信息。
换句话来说，如果字段值为一个，则说明调度的多个数据采用相同的TPC指示；如果字段值为多个，则说明调度的多个载波上的多个数据采用不同的TPC指示。
(5)、调制与编码策略(modulation and coding scheme，MCS)指示信息
本申请实施例中，针对调度的多个数据可以采用相同或不同的MCS指示信息。示例性的，如果MCS指示信息对应的字段值为一个(例如为1)，则说明调度的多个数据的MCS相同；如果MCS指示信息对应的字段值为多个(例如为1、2、3)，则说明调度的多个数据的MCS不同。需要说明的是，多个字段值与多个数据可一一对应。
(6)、新数据指示(new data indicator，NDI)信息
本申请实施例中，NDI信息可用于指示数据为新传数据或者重传数据。示例性的，当NDI的字段的值为“0”时，调度指示信息用于指示多个数据为新传数据，当NDI的字段的值为“1”时，调度指示信息用于指示多个数据为重传数据；或者，当NDI的字段的值为“1”时，调度指示信息用于指示多个数据为新传数据，当NDI的字段的值为“0”时，调度指示信息用于指示多个数据为重传数据。
作为另一示例，当NDI的字段的值为一个值时，调度指示信息用于指示多个数据均为新传数据或均为重传数据，例如0表示多个数据均为新传，1表示多个数据均为重传。当NDI的字段的值为多个值时，每一个值分别指示多个数据中的一个数据为新传还是重传数据，例如调度四个数据，NDI的字段的值对应四个值，0010，即表示第三个数据为重传，其它的数据为新传数据。
(7)、信道接入指示信息
在非授权频谱，需要指示终端设备进行先听后说(listen-before-talk，LBT)LBT的具体参数，例如包括LBT类型，信道接入优先级等的一种或多种。在一种可能的实现中，可 以针对调度的多个数据采用相同的或不同信道接入指示。示例性的，如果信道接入指示信息对应的字段值为一个(例如为1)，则说明调度的多个数据的信道接入指示信息相同；如果信道接入指示信息对应的字段值为多个(例如为1、2、3)，则说明调度的多个数据的信道接入指示信息不同。需要说明的是，多个字段值与多个数据可一一对应。
(8)、时域资源指示信息
在一种可能的实施方式中，针对调度的多个数据可以采用相同或不同的时频资源指示信息。作为一种示例，如果时频资源指示信息对应的字段值为一个，则说明调度的多个数据的时频资源指示信息相同；如果时频资源指示信息对应的字段值包括多个，则说明调度的多个数据的时频资源指示信息不同。需要说明的是，多个字段值与多个数据可一一对应。
(9)、频域资源指示信息
在一些实施例中，频域资源指示信息可用于指示不同载波上的多个数据的频域资源的集合。若频域资源指示信息对应的字段值为一个，则说明所述多个数据的频域资源可以通过所述一个字段值确定。示例的，所述调度的多个数据的频域资源位置相同，或者所述调度的多个数据的频域资源的相对位置相同，或者所述一个字段值指示的是所述多个数据的频域资源的合集；若频域资源指示信息对应的字段值为多个，则说明调度的多个数据的频域资源位置不同。需要说明的是，如果频域资源指示信息对应的字段值为多个，那么多个数据与频域资源指示信息对应的字段值可一一对应。
在另一些实施例中，频域资源指示信息可用于指示多个数据中的一个数据的频域资源位置。示例性的，频域资源指示信息对应的字段值可以为多个数据中的任意一个数据的频域资源位置，那么其它数据的频域资源位置可通过该字段值推算得到。
举例来说，假设频域资源指示信息对应的字段(frequency domain resource allocation，FDRA)的值为“1”，并且该字段的值为多个数据中的第一个数据的频域资源位置，那么第二个数据的频域资源位置为第一个数据的频域资源位置+1，即第二数据的频域资源位置为2，以此类推可得到其它数据的频域资源位置。可以理解的是，这里的“1”仅是为了便于理解，实际应用中取决于数据的大小，可约定预设的偏移值来推断其他数据的频域资源位置。
当然，可以理解的是，上述信息仅是一些示例，本申请实施例中还可以包括其它的指示信息，对此不作限定。
通过上述实施例，可以实现通过一个控制信息，调度不同载波上的多个数据，相比于现有技术，如果要调度不同载波上的多个数据，就不需要多个控制信息才能完成多个数据的调度，可大大降低信令开销，提升通信效率。
在一些场景下，载波组内聚合的多个载波的资源栅格是对齐的，或者说多个载波基于相同的资源栅格进行资源划分。例如图2所示，聚合的多个载波的资源块是完全连续排布的，例如按照从左到右的顺序，载波1的最后一个资源块和载波2的第一个资源块之间在频域上无间隔。
在另一些场景下，载波组内聚合的多个载波的资源栅格是不对齐的，例如图5所示，聚合的多个载波的资源块并非完全连续排布，例如载波1的最后一个资源块和载波2的第一个资源块之间在频域上存在间隔。此时，网络设备可确定公共资源栅格，如公共资源栅格为载波1对应的资源划分方式，则所述间隔信息对应的是载波2所对应的资源栅格相对于公共资源栅格的偏移，称为资源栅格偏移。网络设备通过系统消息和/或配置信息(如无 线资源控制(radio resource control，RRC)信令)和/或者动态指示信息(如DCI等控制信息)将所述公共资源栅格信息，以及载波i对应的资源栅格偏移信息通知给终端设备。
相应的，终端设备可根据所述公共资源栅格信息，以及载波i的资源栅格偏移，确定载波i上的资源的准确位置。在一些场景下，即使相邻的载波对应的资源块之间存在间隔，其资源块索引仍可以连续。例如，载波1的最后一个资源块和载波2的第一个资源块之间在频域上存在间隔，示例的，载波1的最后一个资源块的索引为RB#12，载波2的第一个资源块的索引为RB#13，其索引值仍然连续。
以下针对频域资源指示信息介绍如何确定多个数据中每个数据的频域资源位置。
作为一种可能的实现方式，频域资源指示信息中可包括资源指示值(resource indicator value，RIV)，或者频域资源指示信息通过RIV的方式实现。根据该RIV可确定出一段连续的资源块中起始资源块的索引RB start和资源块的个数L，进而终端设备可以根据RB start和L确定出连续资源块的索引为：RB start到RB start+L-1。示例性的，参阅图6A所示，为一段连续的资源块示意图，假设资源块从0开始编号，图示中箭头所指的资源块0可以为起始资源块。可以理解的是，连续的资源块可以为单个载波内的一段连续的资源块，也可以为多个载波上的一段连续的资源块。可以理解的，所述连续的资源块可以为物理上无间隔连续的多个资源块，也可以是逻辑上连续的资源块，即资源块对应的索引编号连续。
在本申请中，频域资源指示信息中包括的RIV可以包括一个或多个。当频域资源指示信息中包括的RIV值为一个时，RIV可以用于指示多个数据的频域资源的集合，或者用于指示多个数据的频域资源的并集；或者RIV用于指示多个数据中的其中一个数据的频域资源。当频域资源指示信息中包括的RIV值为多个时，每一个RIV值可对应多个数据中的一个数据。也就是说，根据RIV值可确定出每一个数据的频域资源位置。换言之，如果RIV相同时，那么RIV值就只有一个，如果RIV不同时，那么RIV值就包括多个。
以下针对下述两种情况进行具体说明。
第一种情况：RIV用于指示不同载波上的多个数据的频域资源的集合或并集。
可以理解的是，并集(或者称为“合集”)指的是多个数据的频域资源的总和。
假设BWP内包括N(N>＝1)个载波，
Figure PCTCN2020121677-appb-000003
表示BWP内第i个载波的起始资源索引(i＝0～N-1)，
Figure PCTCN2020121677-appb-000004
表示载波i的终止资源索引，
Figure PCTCN2020121677-appb-000005
表示在第i个载波上的数据对应的起始资源索引，
Figure PCTCN2020121677-appb-000006
表示在第i个载波上的数据对应的终止资源索引。
根据RIV确定的频域资源的集合为从RB start作为起始RB的连续的L个RB。
那么，第i个载波的起始资源索引与第i个载波上的数据对应的起始资源索引的关系可以满足下述公式：
Figure PCTCN2020121677-appb-000007
第i个载波的终止资源索引与第i个载波上的数据对应的终止资源索引的关系可以满足下述公式：
Figure PCTCN2020121677-appb-000008
根据上述两个公式可得到第i个载波上的数据对应的起始资源索引以及终止资源索引， 这样就可确定出每一个数据的频域资源位置。
通过这种指示方式，可以通过一个资源指示值实现多个数据的频域资源指示，降低开销，提高通信效率。
第二种情况：RIV用于指示不同载波上的多个数据中的一个数据的频域资源位置。
假设BWP内包括N(N>＝1)个载波，
Figure PCTCN2020121677-appb-000009
表示BWP内第i个载波的起始资源索引(i＝0～N-1)，
Figure PCTCN2020121677-appb-000010
表示载波i的终止资源索引，
Figure PCTCN2020121677-appb-000011
表示在第i个载波上的数据对应的起始资源索引，
Figure PCTCN2020121677-appb-000012
表示在第i个载波上的数据对应的终止资源索引。
同样，根据RIV确定的频域资源的集合为从RB start作为起始RB的连续的L个RB。但此时RB start对应起始RB索引为相对于第i个载波上的索引。
那么，第i个载波的起始资源索引与第i个载波上的数据对应的起始资源索引的关系可以满足下述公式：
Figure PCTCN2020121677-appb-000013
第i个载波的终止资源索引与第i个载波上的数据对应的终止资源索引的关系可以满足下述公式：
Figure PCTCN2020121677-appb-000014
或者，
Figure PCTCN2020121677-appb-000015
其中，
Figure PCTCN2020121677-appb-000016
表示在第i个载波上的数据的起始资源索引。
需要说明的是，针对第二种情况，根据RIV指示信息确定的起始资源索引为相对于每个载波上的起始资源索引。通过这种方式，即采用相同的指示信息实现多个数据的频域资源指示，可以降低开销，提高通信效率。
由于N个载波中任意两个相邻的载波之间存在保护间隔(或者也称为保护频带(guard band))，参阅图6B所示，图中黑色区域为保护间隔，那么实际的起始资源索引和终止资源索引为减掉保护间隔之后的资源索引。示例性的，载波2的起始资源索引为箭头2所指的起始资源索引。需要说明的是，在一些场景下，上述计算公式中的起始资源索引和终止资源索引为实际的起始资源索引和实际的终止资源索引，即为去除掉保护间隔之后的资源索引。
可以理解的，在一些场景下，图中所示的保护间隔可以是资源块的整数倍，且保护间隔所包含的资源块具有跟其它资源块统一的索引。以图6B为例，假设载波1的最后一个资源块为RB#9，即对应的索引为9，保护间隔包含2个资源块，对应的索引为10和11，即跟其它资源块统一顺次编号，载波2的第一个资源块对应的索引为12。
在另一些场景下，保护间隔所包含的资源块跟其他资源块不具有统一的索引，继续以图6B为例，假设载波1的最后一个资源块为RB#9，即对应的索引为9，保护间隔包含2个资源块，但不采用统一索引的方式，载波2的第一个资源块对应的索引为10，忽略保护间隔。此时，载波1的最后一个资源块和载波2的第一个资源块的索引仍然连续。
可以理解的是，图6B中所示的FDRA所对应的资源块集合即为RIV所指示的多个数 据的频域资源的集合。
作为一种可能的实现方式，在载波i上的数据所对应的实际的起始资源索引＝RIV指示的起始资源索引+偏移信息。其中，示例性地，偏移信息为保护间隔的大小，可以通过资源块的个数来表示，或者可以通过其他资源单元(如资源元素(resource element，RE)，子载波)的个数来表示，或者偏移信息通过除了RIV的其他指示信息指示。比如，指示的起始资源索引为0，例如图中箭头1所指的起始资源索引，保护间隔为1个RB，即偏移信息为1，那么实际的起始资源索引＝0+1＝1。即载波2上的箭头2所指的起始资源索引为1。
可以理解的是，如果一个或多个RIV指示的多个数据对应的资源块的集合为集合A，BWP内第i个载波内的可用资源的集合为集合B，那么调度的多个数据中在第i在载波上的数据对应的频域资源为集合A和集合B的交集。
作为一种可能的实现方式，频域资源指示信息中可以包括位图(bitmap)。根据bitmap个数的不同，可包括以下两种情况：
第一种情况：当频域资源指示信息中包括一个bitmap时，bitmap可以用于指示多个数据对应的资源块的集合。
其中，bitmap中的每一个比特位对应一个或多个资源块。示例性的，假设bitmap中的每一个比特位对应一个资源块，BWP内包括4个资源块，并且当比特位的值为“1”时，表示资源块被调度；当比特位的值为“0”时，表示资源块没有被调度，那么对于“1101”可表示BWP内的资源块1、资源块2和资源块4被调度。
当然，可以理解的是，上述仅是一种示意性说明，例如还可以为当比特位的值为“1”时，表示资源块没有被调度；当比特位的值为“0”时，表示资源块被调度，本申请对此不作限定。
假设BWP内包括N(N>＝1)个载波，
Figure PCTCN2020121677-appb-000017
表示BWP内第i个载波的起始资源索引(i＝0～N-1)，
Figure PCTCN2020121677-appb-000018
表示载波i的终止资源索引，则BWP内第i个载波内的可用资源的集合为：
Figure PCTCN2020121677-appb-000019
需要说明的是，此处的起始资源索引和终止资源索引表示实际的起始资源索引和实际的终止资源索引，具体的，实际的起始资源索引和实际的终止资源索引可参阅上述介绍，此处不再重复赘述。
如果bitmap指示的多个数据对应的资源块的集合为集合A，BWP内第i个载波内的可用资源的集合为集合B，那么调度的多个数据中在第i在载波上的数据对应的频域资源为集合A和集合B的交集。
第二种情况：当频域资源指示信息中包括多个bitmap时，每一个bitmap可以用于指示每个载波上的数据对应的资源块集合。也就是说，多个bitmap与每个载波上的数据对应的资源块集合之间具有一一对应关系。
其中，每一个bitmap的长度取决于每个载波内的可用资源的大小。若载波内的可用资源较大，则bitmap的长度较长；若载波内的可用资源较小，则bitmap的长度较短。并且，每一个bitmap中的每一个比特位可对应一个或多个资源块。
示例性的，假设BWP内包括的载波1中包括4个资源块，并且当比特位的值为“1”时，表示资源块被调度；当比特位的值为“0”时，表示资源块没有被调度，那么对于“1101”可表示载波1内的资源块1、资源块2和资源块4被调度，资源块3没有被调度。
基于上述实施例，终端设备可根据频域资源指示信息确定出被调度的多个数据对应的频域资源位置，并且可以实现通过一个指示信息，对多个数据的资源位置进行指示，从而提高通信效率。
进一步的，在BWP内包含多个载波的部分或全部资源块的场景下，对于控制信息所对应的搜索空间，可以限制在单个载波内，且网络设备可以选择BWP内包含的多个载波中的一个或多个作为主载波，进行搜索空间的配置。示例性的，BWP内包括三个载波，例如载波1、载波2和载波3，则网络设备可以选择三个载波上的至少一个作为主载波，例如选择载波1作为主载波。
可以理解的是，搜索空间为终端设备盲检控制信息对应的搜索资源范围，即终端设备在搜索空间内盲检控制信息。通过将搜索空间固定配置在某个载波上，可以有效降低终端设备的盲检开销。
