对mMTC类业务，由于其业务种类千差万别，对网络需求存在很大差异。大致来说，会存在如下两种需求的业务：一种是需要可靠传输，但对时延不敏感的业务；另一种是需要低延迟，并且高可靠传输的业务。对于需要可靠传输但对时延不敏感的业务，较容易处理；但是，对于需要低延迟并且高可靠传输的业务，如果传输不可靠，会导致重传而造成传输时延过大，不能满足要求。
为了解决未来网络中大量的mMTC类业务，以及满足低时延、高可靠的业务传输，上行免授权(Grant Free)传输的方案将应用到此类业务中。在免授权传输***中，存在大量的终端，但同时接入网络的终端数量很少，终端可以随机选择免授权传输资源发送数据。
免授权传输机制下，基站需要在免授权传输资源上对终端发送的上行数据进行盲检，解调复杂度极高，如何降低解调复杂度是亟待解决的技术问题。

其中，所述配置信息还包括所述上行传输时频资源内可用时频资源块的数目的上限值。
其中，所述配置信息还包括上行传输时频资源内各个时频资源块的长度或终止位置。
其中，所述配置信息通过信令显性指示或者通过导频图案隐性指示或者导频序列指示。
给每个时频资源块配置好配置信息之后，网络设备向终端发送多个时频资源块和对应的配置信息；在一种可能的实现方式中，网络设备是在终端有上行信号需要发送之前，向终端发送的配置信息。
终端接收网络设备向其发送的多个时频资源块和对应的配置信息，并保存在本地，以备进行上行传输时使用；
当终端有上行数据需要发送时，从所述多个时频资源块中选择进行上行传输的一个或时频资源块；该配置信息中配置了终端进行上行传输的时频资源块参数和覆盖增强所需的参数，时频资源块参数至少包括时频资源块的标识信息，该标识信息可以是资源块的起始位置，也可以是资源块的索引号，此外，所述时频资源块参数还包括时频资源块的长度或时频资源块的终止位置，时频资源块的粒度等等；而覆盖增强所需的参数例如功率控制参数或TTI bundling size指示或者Repetition size指示等参数信息。最后，发送上行数据时，所述根据所述选择的至少一个时频资源块的配置信息，在所 述选择的至少一个时频资源块上传输上行数据。
一种可选的实施方式中，终端在发送上行数据时，还可以将其选择的时频资源块的标识信息通知给网络设备。所述时频资源块的标识信息可以与所述上行数据一起发送，也可以独立发送(即不与所述上行数据一起发送)。
具体的，当时频资源块的配置信息包括起始位置或索引号时，终端以该时频资源块的起始位置或索引号指示的时频资源块发送上行数据；当时频资源块的配置信息进一步包括起始位置和长度时，终端以该时频资源块的起始位置为起点，在该长度对应的时频资源块上发送上行数据；当时频资源块的配置信息包括起始位置和终止位置时，终端以该时频资源块的起始位置为起点以终止位置为时频资源块的终点所代表的时频资源块上发送上行数据；当时频资源块的配置信息包括起始位置和粒度时，终端以该时频资源块的起始位置为起点，以粒度为时频资源的宽度所代表的时频资源块上发送上行数据；当时频资源块的配置信息包括起始位置和功率控制参数时，终端以该时频资源块的起始位置为起点，以功率控制参数表示的功率，在对应的时频资源块上发送上行数据；当时频资源块的配置信息包括起始位置和TTI bundling size指示时，终端以该时频资源块的起始位置为起点，以TTI bundling size指示的几个时间间隔，在绑定几个时间单位发送上行数据；终端以该时频资源块的起始位置为起点，在Repetition size指示为几个重复传输时间单位发送上行数据。
网络设备通过盲检的方式接收来自终端的上行数据能正确解调。相比现有技术而言，由于配置信息中指示了时频资源块的标识信息，根据该标识信息网络设备的盲检是在有限范围内有限次数的盲检，无需网络设备通过多次盲解来尝试多种可能，从而能够降低盲检的复杂度。
一种可能的实现方式中，终端还将其选择的至少一个时频资源块的标识信息携带在所述上行信息中发送给网络设备；
另一种可能的实现方式中，终端将其选择的至少一个时频资源块的标识通过上行控制信令发送给网络设备，上行数据通过数据信道发送给网络设备；
再一种可能的实现方式中，网络设备通过检测终端发送的序列判断对应的时频资源块的起始位置，并在该起始位置上检测终端传输的上行数据上述三种方式，都能使得网络设备能正确解调，进一步降低解调的复杂度。
实施本申请提供的数据传输方法，由于网络设备为终端预分配的上行传输时频资源划分为多个时频资源块，因此终端可以选择更窄带宽的时频资源进行上行传输，提高了终端的发射功率；进一步的，网络设备还为每一个时频资源块配置了配置信息，该配置信息可以携带子带参数或者覆盖增强参数，或者同时携带子带参数和覆盖增强参数，因此，终端选择了进行上行传输的时频资源块之后，根据对应配置信息进行上行传输，可以进一步的提高发射功率；而网络设备也能根据配置信息在正确的时频资源块上进行解调，从而提高解调的效率，避免产生处理时延。

具体实施方式
在通信***中，为了保证数据正确传输或通信质量，通常采用如下两种方式中的至少一种：
(1)通过TTI bundling(transmission time interval bundling，传输时间间隔绑定)的方式，使得终端在连续的几个子帧上传输相同的信号，由网络设备对这几个子帧上传输的信号进行合并，从而提升信号解调的质量；
(2)提升终端单次发送信号的功率。
目前，在长期演进(Long Term Evolution，简称为“LTE”)***的授权传输机制下，为了保证数据的正确传输，基站可以实时调整每个终端进行上行传输的时频资源，例如：
当终端有上行数据需要发送时，终端向基站发送上行资源调度请求，为了提升通信质量，基站可以给终端配置多个子帧或时隙(slot)，以便终端进行TTI bundling；或基站减小终端在频域上的传输带宽，以便提升终端在单个时频资源块(Resource Block，RB)的发送功率；或者基站对终端采用前述两种方式的组合。
相应的，终端依据基站的调度发送上行数据，基站在调度信息指定的时频位置进行数据解调。
新的通信需求对现有网络提出了包括技术上和商业模式上的种种挑战，需要下一代移动网络(Next Generation Mobile Network，NGMN)来满足。如图1所示，NGMN主要将移动网络业务划分为三类场景：增强移动宽带(eMBB，Enhanced Mobile Broadband)，低时延高可靠性通信(uRLLC，Ultra-reliable and Low-latency Communications)以及大规模机器通信(mMTC，Massive Machine Type Communications)。
mMTC覆盖对于联接密度要求较高的场景，例如智慧城市，智能农业，满足人们对于数字化社会的需求。该场景的典型特征是大连接，即终端数量庞大，业务类型以小数据包业务为主，而且对低时延有一定的要求。
uRLLC聚焦对时延极其敏感的业务，例如自动驾驶/辅助驾驶；对车联网、无人驾驶、工业控制等业务来说，***容量并不是主要的问题，但是对于时延和可靠性却有着很高的要求。
在以上两种场景中，免授权传输被认为是一种优于授权传输、更加适用的上行数据传输方法。免授权传输相比于基站调度的授权传输方案，不必经过发送上行资源调度请求和等待接收基站的授权这一过程，大大缩短了传输时延，可以满足在时延方面的需求。
但是，发明人发现，在免授权传输机制下，终端进行数据传输的资源是事先预留的，并且预留的资源在某些场景下通常针对多个终端。为了解决覆盖问题，若基站根据终端覆盖需求的变化进行预留资源的实时调整，会引入较大的信令开销和传输时延。
另一方面，如果终端自行调整传输资源及对应发送参数时，基站预先不知道终端数据传输出现的时频位置，需要通过多次盲解来尝试多种可能，会增加解调的复杂度 和处理时延。
有鉴于此，为了解决未来网络大量的uRLLC和mMTC类业务，以及满足低时延、高可靠的业务传输，在免授权传输机制下解决覆盖增强的技术问题，本申请实施例提出了一种技术方案：将为终端配置的上行传输时频资源划分成多个时频资源块，因此终端可以选择更窄带宽的时频资源进行上行传输，从而增加终端的发射功率。进一步的，网络设备为每个子时频资源块配置对应的配置信息，该配置信息可以携带时频资源块参数或者覆盖增强参数，或者两个参数都携带，因此，终端选择了进行上行传输的时频资源块之后，根据对应配置信息进行上行传输，可以进一步的提高发射功率；而网络设备也能根据配置信息在正确的时频资源块上进行解调，从而提高解调的效率，避免产生处理时延。
应理解的是：为了保证上述提及的uRLLC和mMTC场景下进行免授权传输的可靠性，本申请实施例提供了一种上行传输技术。当然本申请提供的技术方案不仅仅限于应用在uRLLC和mMTC场景下，在其他任何一种不需要基站调度的免授权传输场景中，都可以应用本申请提供的数据传输方法，终端和网络设备。

免授权传输可以指：终端在不需要网络设备授权的情况下进行上行数据传输。所述授权可以指终端发送上行调度请求给网络设备，网络设备接收调度请求后，向终端发送上行授权，其中所述上行授权指示分配给终端的上行传输资源。

上文中结合图2描述了本申请实施例的应用场景，下面将分别从网络设备和终端的角度描述本申请实施例的数据传输方法的实现过程，在此之前，先对本申请实施例中的上行传输时频资源的划分过程做详细描述。
现有技术如图3所示，网络设备给终端预留的用于上行免授权传输的时频资源，或者将用于免授权传输的竞争传输单元(Contention Transmission Unit，CTU)预留给终端，并告知终端多个传输资源；终端有上行数据传输需求时，从网络设备预先分配的多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据；网络设备在所述预先分配的多个传输资源中的一个或多个传输资源上检测终端传输的上行数据。所述检测可以是盲检测，也可能根据所述上行数据中某一个控制域进行检测，或者是其他方式进行检测。
本申请实施例划分上行传输时频资源是将用于免授权传输的上行传输时频资源进一步划分为多个时频资源块。如此，终端在更窄带宽的时频资源上进行上行传输，其发射功率可以得到增强，能获得更好的传输性能。
需要说明的是，所述上行传输时频资源可配置的范围为一组终端进行上行免授权传输的时频资源或者整个带宽的时频资源。以上两种方式中，时频资源块的大小可以不同，也可以相同，具体的，时频资源块在频域维度上以子带区分所述多个时频资源块中每个时频资源块所占的带宽相同，或者所述多个时频资源块中至少有两个时频资源块所占的带宽不同；每个子带包含的子载波个数可以相同也可以不同。一种具体的实现方式中，所述每个时频资源块为一个子带。
时频资源块在时域维度上以子帧或者时隙，或者小时隙区分，每个时频资源块在时域上所占的符号数相同，或至少有两个时频资源块在时域上所占的符号数不同，可以根据需要灵活划分；终端可以根据传输需要灵活选择适合当前传输的时频资源块大 小。
需要说明的是，对于时频资源块的划分，可以先从频域上将其划分为多个子带，可选的，再将一个子带在时域上划分成多个时频资源块。也可以先从时域上将其划分为多个小的时频资源，然后再将一个时域单位的时频资源从频域上划分为子带。
一种可能的实现方式中，由网络设备将所述上行传输时频资源划分成多个时频资源块，存储被划分成多个时频资源块的上行传输时频资源；
另一种可能的实现方式中，由设备开发或维护人员，将表示把所述上行传输时频资源划分成多个时频资源块的表格或者参数信息配置在所述网络设备上。
划分上行传输时频资源的方式包括但不限于如下两种：
方式一：将上行传输时频资源与特定终端组进行关联。例如，将上行传输时频资源先按照终端组进行划分，然后将每个终端组的上行传输时频资源再进一步划分成不同的时频资源块；或者，将上行传输时频资源再进一步划分成不同的时频资源块，然后将这些时频资源块分配给不同的终端组。
具体如图4所示：网络设备为多个终端配置的免授权上行传输时频资源被首先划分为两部分：第一部分被终端组1共享；第二部分被终端组2共享；进一步的，第一部分资源又被划分为时频资源块1-1，时频资源块1-2，时频资源块2，时频资源块3，时频资源块4；第二部分资源又被网络设备划分为时频资源块1，时频资源块2，时频资源块3，时频资源块4。这里的时频资源块1-1和时频资源块1-2，其在时域上所占的子带的带宽相同(都占用子带1)，但是占用不同的时隙，例如时频资源块1-1占用时隙1，时频资源块1-2占用时隙2；时频资源块4-1，和时频资源块4-2同理。需要说明的是，这里的子带包含不同个数的子载波；时隙包含不同的符号数。
图5是另一种实现方式，网络设备为多个终端配置的免授权上行传输时频资源被首先划分为两部分：第一部分被终端组1共享；第二部分被终端组2共享；进一步的，第一部分资源又被网络设备划分为多个时频资源块，每个时频资源块为一个子带，例如：子带1，子带2，子带3，子带4；第二部分资源又被网络设备划分为子带1，子带2，子带3，子带4。
这种划分方式，使得网络设备对于传输资源的控制更加准确，其在不同的时频资源块上进行检测的时候，就知道该时频资源块被哪组的终端所使用，从而提高了检测效率。方式二：不区分终端组，即直接将上行传输时频资源划分成不同的时频资源块，终端选择哪个时频资源块，则使用对应的时频资源块进行上行传输。
具体如图6所示：网络设备为多个终端配置的免授权上行传输时频资源直接被网络设备划分为时频资源块1-1，时频资源块1-2，时频资源块2，时频资源块3，时频资源块4-1，时频资源块4-2，时频资源块5，时频资源块6，时频资源块7，时频资源块8。该时频资源块1～时频资源块8可以被多个终端共享。
如图7所示是另一种实现方式：网络设备为多个终端配置的免授权上行传输时频资源直接被网络设备划分为多个时频资源块，每个时频资源块为一个子带；例如子带1，子带2，子带3，子带4，子带5，子带6，子带7，子带8。该子带1～子带8可以被多个终 端共享。
这种划分方式，使得终端在进行时频资源块的选择时，更加的灵活，其传输性能更优。
以上两种方式中，时频资源块的大小可以不同，也可以相同，具体的，该时频资源块在频域维度上以子带区分，其子带所占的带宽可以相同也可以不同。应理解的是，子带的粒度可以是子载波，或者RB或者RBG；在时域维度上以符号数进行区分，其符号数有多有少或者相同，可以根据需要灵活划分，终端可以根据传输需要灵活选择适合当前传输的时频资源块大小。当然，这里仅为举例，在时域维度上还可以以时隙或者小时隙进行区分。
在上述两种将上行传输时频资源划分成时频资源块的基础上，本申请实施例的网络设备进一步为时频资源块配置对应的配置信息，该配置信息主要包括时频资源块参数和覆盖增强参数，这里所说的时频资源块参数是跟时频资源块相关的信息，例如时频资源块的标识信息(起始位置或索引号)，时频资源块的数目，数目的上限值，时频资源块的粒度，粒度的长度中的一种或多种；而覆盖增强参数是用于通过增强信号的接收功率，来提升接收信噪比，满足覆盖的要求的参数，例如功率控制参数，TTI bundling size指示或Repetition size指示等等。
参见图8，基于上述网络设备将用于免授权传输的上行传输时频资源划分为多个上行传输时频资源块，并为每个上行传输时频资源块分别配置对应的配置信息，本申请实施例提供的数据传输方法如下：
步骤101，网络设备向终端发送用于传输上行数据的时频资源的信息，所述时频资源包括多个时频资源块，所述时频资源的信息中包括每个时频资源块及其对应的配置信息；所述配置信息中至少包括对应时频资源块的标识信息，该标识信息可以是时频资源块的起始位置或索引号；可选的，网络设备在终端需要发送上行数据之前，向终端发送用于传输上行数据的时频资源的信息；
步骤102，终端保存网络设备分配的多个时频资源块和对应的配置信息；
步骤103，终端有上行数据需要发送时，从多个时频资源块中选择用于传输上行数据的至少一个时频资源块；
步骤104，终端根据所述选择的至少一个时频资源块的配置信息，在所述选择的至少一个时频资源块上传输上行数据；
步骤105，网络设备接收终端在所述时频资源块上向其发送的上行数据。
实施本申请提供的数据传输方法，由于网络设备为终端预分配的上行传输时频资源划分为多个时频资源块，因此终端可以选择更窄带宽的时频资源传输上行数据，提高了终端的发射功率；进一步的，网络设备还为每一个时频资源块配置了配置信息，该配置信息可以携带时频资源块参数或者覆盖增强参数，或者两个参数都携带，因此，终端选择了用于传输上行数据的时频资源块之后，根据对应配置信息进行传输上行数据，可以进一步的提高发射功率；而网络设备也能根据配置信息在正确的时频资源块上进行解调，从而提高解调的效率，避免产生处理时延。
本申请实施例提供的数据传输方法，在网络设备采用上述方式一对上行传输资源 进行划分时，即将时频资源块与终端组进行关联，具体包括：
信息1：针对多个终端组的上行传输时频资源的时频资源块划分信息，该信息1可以向小区内所有终端进行发送，也可以仅告知每个终端组内的终端其所在终端组对应的上行传输时频资源的划分情况；
信息2：时频资源块对应的覆盖增强参数；
该信息2发送的对象可以是终端组内的多个终端；
信息3：时频资源块与终端组的映射关系。
该信息3可以发送给同一终端组内的每一个终端。
上述的信息1是终端进行免授权传输的基本配置，用于指示网络设备为终端组或终端预留的上行传输时频资源。而信息2和信息3为可选的，其涉及的覆盖增强参数用于指示终端如何使用该上行传输时频资源实现覆盖增强。时频资源块的配置信息中的标识信息，可以是信息1中时频资源块的起始位置或者索引号。
具体的，当网络设备针对多个终端组的上行传输时频资源的时频资源块进行划分时，可以给每个时频资源块分配一个索引号，如表1所示：
表1
时频资源块 索引号
时频资源块1 1
时频资源块2 2
时频资源块3 3
时频资源块4 4
时频资源块5 5
时频资源块6 6
时频资源块7 7
时频资源块8 8
终端在选择时频资源块进行上行传输的时候，可以将其选择的时频资源块的索引号发送给网络设备，以便网络设备能准确检测。
若加上终端组的映射关系，如表2所示：
表2
时频资源块 索引号 所属终端组
时频资源块1 1 1
时频资源块2 2 1
时频资源块3 3 1
时频资源块4 4 1
时频资源块5 5 2
时频资源块6 6 2
时频资源块7 7 2
时频资源块8 8 2
包括时频资源块参数或者覆盖增强参数的信息2，在后续详细描述。
上述的信息1、信息2、信息3在具体实现中，可通过***消息或RRC(radio resource control，无线资源控制)信令或MAC CE(medium access control control element，媒体接入控制控制元素)或DCI(downlink control information，下行控制信息)承载。
结合各种信令所能携带的信息量，采用如表3所示的信令组合来实现配置信息的承载：
表3
处理流程 ***消息 RRC信令 MAC CE DCI
方式1 信息1 信息2，信息3    
方式2 信息1 信息2 信息3  
方式3 信息1 信息2   信息3
方式4 信息1   信息2，信息3  
方式5 信息1   信息2 信息3
方式6   信息1，信息2，信息3    
方式7   信息1 信息2，信息3  
方式8   信息1 信息2 信息3
一种实现方式是：上述信息1可以通过由网络设备在进行***配置的时候，通过***消息发送至终端，然后在RRC承载建立的时候，网络设备再把信息2和信息3通过RRC信令发送至终端；又一种实现方式是：上述信息1，信息2，信息3通过RRC信令进行承载的方式，其信令的开销更小，灵活程度更高。
应理解的是，上述方式1～方式8仅为举例，网络设备还可以根据实际需求，采用更多的信令组合方式将配置信息发送到终端。
下面将从不同的信令承载方式描述以时频资源块为单位划分上行传输时频资源且与终端组相关联的方式一中，本申请实施例的数据传输方法的实现过程。应理解的是，下面的实施例描述了上行传输时频资源被划分为多个时频资源块具体是多个子带形式时，其配置信息及其承载实现形式。如果时频资源块以时域为维度进行划分更小的时频资源块时，其起始位置，数目，长度等指示方式加上对应的时隙或者符号标识即可。
实施例一:以RRC信令承载配置信息
此种方式是定义一种新的RRC信令，并放在RRC连接建立(RRC Connection Setup) 中进行传递。
实施例一的第一种实现方式是：RRC中携带的配置信息包含时频资源块的划分信息，例如时频资源块的起始位置，使得终端可以选择合适的时频资源块进行传输。这里，时频资源块的长度则默认持续到下一个时频资源块的起始位置。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000001
若时频资源块在子带的基础上，进一步以时域为维度进行划分更小的时频资源块时，上述配置消息中还将携带时域上的起始位置，比如第几个符号。
本申请实施例中，也可以先以时域为维度对上行时频资源进行划分，再以频域为维度对上行时频资源进行划分，得到多个时频资源块。后续实施例原理相同，在此不再赘述。
实施例一的第二种实现方式是：RRC中携带的配置信息包含时频资源块的划分信息，例如时频资源块的长度，使得终端可以选择合适的时频资源块进行传输，从而提高发射功率。这里，第一个时频资源块的频域上的起始位置可以是可用子带的起始位置，后续子带的起始位置是“子带起始位置+前面所有的子带长度+1”；第一个时频资源块的时域上的起始位置可以是可用符号的起始位置，后续时频资源块的起始位置是“符号起始位置+前面所有的符号长度+1”。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000002
Figure PCTCN2018080551-appb-000003
若以时域为维度进行划分更小的时频资源块时，上述消息格式还可以是携带时域上的长度，比如“符号起始位置+前面所有的符号长度+1”。
实施例一的第三种实现方式是：RRC中携带的配置信息包含时频资源块的划分信息，例如时频资源块的起始位置和时频资源块的长度等，使得终端可以选择合适的时频资源块进行传输，从而提高发射功率。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000004
若时频资源块在子带的基础上，进一步以时域为维度进行划分更小的时频资源块时，上述消息格式还将携带时域上的起始位置和长度，比如“起始位置为第4个符号，其长度为n”。
实施例一的第四种实现方式是：在RRC中携带的配置信息不仅包含时频资源块划分信息，还进一步包含时频资源块对应的功率控制参数。终端使用不同的时频资源块 发送上行数据时，不同的时频资源块对应的功率等级配置为不同，如此提高覆盖增强。具体实现中，网络设备可以使用3个比特对功率等级进行量化，000表示发射功率用总功率的(1/2) o进行发送，而001标识用总功率的(1/2) 1进行发送，以此类推。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000005
若以时域为维度进行划分更小的时频资源块时，上述消息格式可以指示该的时频资源块的控制控制参数。
上述四种实现方式中，各字段的含义如下：
Figure PCTCN2018080551-appb-000006
Figure PCTCN2018080551-appb-000007
进一步的，对于RRC信令来讲，网络设备还可以同时定义时频资源块数目的上限值，以时频资源块是子带为例，例如：
maxNarrowband          INTEGER::＝8
进一步的，网络设备还可以同时定义时频资源块的终止位置。此种情况下，时频资源块的划分信息可以不包含时频资源块的长度，时频资源块的长度则为时频资源块的起始位置到终止位置。
以时频资源块是子带，RRC中携带的配置信息包含子带的起始位置和子带的长度为例，例如：
EndPoint            BIT STRING(SIZE(5))
应理解的是，以上各字段的表示方式和取值仅为举例，本申请实施例的实现方式不仅限于此。
实施例二：用MAC CE信令承载配置信息
本实施例二中，需要网络设备新定义一个MAC CE，并定义对应的MAC子头(sub-header)。
每个子带使用一个MAC CE进行配置；若网络设备需要向终端指示多个时频资源块的配置，则向终端发送多个MAC CE。
新的MAC CE定义如图9所示，其中字段的含义如下：
Figure PCTCN2018080551-appb-000008
对应的MAC sub-header如图10所示，相应的，新定义的MAC CE对应的LCID(Logical Channel ID)如表4所示，该LCID可以使用TS 36321-e00的预留字段，例如10111来关联新定义的MAC CE。
表4
用于下行共享信道的LCID的值(Values of LCID for DL-SCH)
Figure PCTCN2018080551-appb-000009
应理解的是，此处用预留字段10111来表示MAC CE仅为举例，在其他的实现方式中还可以通过其他预留的字段表示。
上述新定义的MAC CE还可由新定义的MAC PDU(MAC Protocol Data Unit，MAC协议数据单元)格式承载，如图11所示，也可以由现有LTE协议定义的DL-SCH(Downlink Shared Channel，下行共享信道)的MAC SDU承载。
为使终端根据传输需求选择相应的时频资源块，本申请实施例中，网络设备还可以对时频资源块的粒度进行配置，也即配置信息中还可以携带时频资源块的粒度，所述时频资源块的粒度包括子载波或RB(resource block)或RBG(resource block group)。这里的一个RB包含12个子载波。
在具体实现中，网络设备可以用2比特信息指示子载波，RB或RBG，如表5所示：
表5
子带粒度指示 含义
00 保留
01 子载波
10 RB
11 RBG
实施例三：用DCI承载配置信息。
本实施例中，将配置信息用DCI进行承载，而DCI承载在PDCCH(physical downlink control channel，物理下行控制信道)里。PDCCH由终端组的RNTI(radio network temporary identifier，无线网络临时标识)加扰，网络设备可对终端组内的一个或多个终端进行配置。
以时频资源块为子带为例，新定义DCI格式(DCI format)，包含下述信息：
-Number of Narrowband–3bits
-For Narrowband 1:
-Start Point-4 bits
-For Narrowband 2:
-Start Point-4 bits
可选择的，DCI格式中还可以包括关于子带的长度的信息：
Length–3 bits
其中，
Number of Narrowband给出了当前DCI消息里配置的子带数目；
Start Point表示子带的起始位置，0001代表从第一个RB，0010代表从第二个RB，以此类推；
Length表示子带的长度，0000代表长度1，0001代表长度2，0010代表长度4，以此类推。
在子带连续配置的情况下，上一个子带的终止位置可以由“下一子带的起始位置-1”得到，因此，子带的配置可以不包含Length字段。
类似的，还可以配置子带的起始位置和终止位置。
同样的，包含子带粒度指示的配置信息也可以通过***消息，RRC信令，MAC CE，或者DCI进行承载，下面将详细描述。
若时频资源块在子带的基础上，进一步以时域为维度进行划分更小的时频资源块时，上述DCI消息格式进一步包含时域上的参数信息。
实施例四：用***消息承载包含时频资源块粒度指示的配置信息
本实施例中，网络设备在***消息中，新增一个RRC信息元素(Radio resource control information elements)用于指示上述时频资源块的粒度。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000010
Figure PCTCN2018080551-appb-000011
其中的字段含义如下：
Figure PCTCN2018080551-appb-000012
该子带的粒度指示信息可以添加在LTE定义的“RadioResourceConfigComm-onSIB”中，由网络设备通过***消息传递给终端。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000013
若以时域为维度进行划分更小的时频资源块时，上述DCI消息格式可以包含时域上的参数信息，原理相同不再赘述。
实施例五：用RRC信令承载包含时频资源块粒度指示的配置信息
本实施例中，网络设备新增一个RRC信息元素(Radio resource control information elements)用于指示上述时频资源块的粒度。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000014
Figure PCTCN2018080551-appb-000015
其中的字段含义如下：
Figure PCTCN2018080551-appb-000016
该子带的粒度指示信息可以添加在LTE定义的“RRCConnectionSetup message”或者“RRC ConnectionReconfiguration message”中，由网络设备通过传递给终端。
若以时域为维度进行划分更小的时频资源块时，上述DCI消息格式可以包含时域上的参数信息。
实施例六：用MAC CE承载包含时频资源块粒度指示的配置信息
实施例六的一种实现方式是：新定义一个MAC CE，并定义对应的LCID，具体表示如图12所示。
其字段含义如下：
Figure PCTCN2018080551-appb-000017
同样的，需要新定义MAC CE对应的LCID。LCID可以使用TS 36321-e00的预留字段，本实施例中，选择10110来关联新定义的MAC CE，更新后的表格如下表6所示：
表6
用于下行共享信道的LCID的值(Values of LCID for DL-SCH)
Figure PCTCN2018080551-appb-000018
应理解的是，此处用预留字段10110来表示MAC CE仅为举例，在其他的实现方式中还可以通过其他预留的字段还表示。同样的，上述新定义的MAC CE还可以由LTE协议定义的DL-SCH(Downlink Shared Channel，下行共享信道)的MAC PDU(MAC Protocol Data Unit，MAC协议数据单元)去承载，如图11所示。
实施例六的第二种实现方式是：在实施例二中如图9所示的新定义的MAC CE基础上扩充字段以表示时频资源块的粒度，具体如图13所示：
其中字段的含义如下：
Figure PCTCN2018080551-appb-000019
此种实现方式中，实施例二中的MAC CE对应的LCID的值保持不变，即不用新增LCID，其可以沿用表4。
为了解决覆盖增强的问题，终端还可以通过TTI bundling或者Repetition的传输方式，在时域内累加功率，从而提高网络设备的解调信噪比。
但是在免授权传输机制下，如果网络设备不知道终端传输使用的TTI bundling size 或者Repetition size配置，则需要尝试不同的绑定大小(bundling size)或者不同的重复传输大小(Repetition size)甚至不同的起始位置区进行数据接收，这种多次尝试的方式会成倍的增加解调的复杂度，也会引入更过的处理时延，因此，本申请实施例的网络设备在为终端配置用于免授权传输的上行传输时频资源时，还可以进一步配置TTI bundling size或Repetition size指示，终端根据该TTI bundling size或Repetition size指示进行上行传输，网络设备便可以采用正确的bundling size或Repetition size进行解调。
以TTI bundling size指示为例进行说明，如下表7所示：
表7
时频资源块索引号 bundling size 含义
1 000 Size＝2 0＝1
2 001 Size＝2 1＝2
3 010 Size＝2 2＝4
… … …
4 110 …
如上表7所示，相同的带宽的时频资源块可以配置不同的bundling size，以便适应终端的不同业务需求。
上述的TTI bundling size指示或Repetition size指示可以在前述实施例一所示的RRC信令或实施例二所示的MAC CE中加入相应的TTI bundling size指示字段来实现，下面仍以TTI bundling size指示为例，通过实施例七和实施例八分别描述。
实施例七：通过RRC信令承载包含TTI bundling size指示的配置信息
本实施例中，仍然需要定义一种新的RRC信令，并放在RRC Connection Setup中进行传递。
实施例七的一种实现方式是：功率控制参数和TTI bundling size指示同时携带在配置信息中，以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000020
Figure PCTCN2018080551-appb-000021
若时频资源块在子带的基础上，进一步以时域为维度进行划分更小的时频资源块时，上述DCI消息格式进一步包含时域上的参数信息。
实施例七的另一种实现方式是：配置信息中携带TTI bundling size指示，不包含功率控制参数，以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000022
其中字段的含义如下：
Figure PCTCN2018080551-appb-000023
若以时域为维度进行划分更小的时频资源块时，上述DCI消息格式可以包含时域上的参数信息。
实施例八：通过MAC CE承载包含TTI bundling size指示的配置信息
本实施例中，需要网络设备新定义一个MAC CE，并且每个时频资源块使用一个MAC CE进行配置；若网络设备需要向终端指示多个时频资源块的配置，则向终端发送多个MAC CE。
实施例八的一种实现方式是：功率控制参数和TTI bundling size指示同时携带在配置信息中，新的MAC CE定义如图14所示，其中字段的含义如下：
Figure PCTCN2018080551-appb-000024
实施例八的另一种实现方式是：配置信息包含TTI bundling size指示，不包含功率控制参数，新的MAC CE定义如图15所示，其中字段的含义如下：
Figure PCTCN2018080551-appb-000025
对应上述两种MAC CE，需要定义对应的MAC子头(sub-header)，对应的MAC sub-header如图10所示，在此不再赘述。
前述实施例一至实施例八分别从网络设备的角度，描述了在采用方式一即将用于免授权传输的上行传输时频资源划分成多个与终端组相关联的时频资源块的基础上，利用RRC，MAC CE，***消息，DCI承载配置信息的实现过程，其中配置信息携带的参数又分为功率控制参数，TTI bundling size指示，时频资源块的粒度，长度，时频资源块索引号，或者时频资源块的起始位置或终止位置等等。
下面，将从终端侧描述在子带与终端组关联的基础上，每个终端进行上行传输的实现方式，其大致可分为以下三种：
第一种：终端随机选择时频资源块进行上行传输。
在基于前述网络设备将用于免授权传输的上行传输时频资源划分成与终端组划相关联的多个时频资源块，且为每个时频资源块配置有进行上行传输的配置信息的基础上，某个终端需要发送上行数据信号时，从自己所属的终端组拥有的时频资源块中，挑选一个或者多个满足自己传输需求的时频资源块进行上行免授权传输。
由于每个时频资源块都配置有配置信息，因此终端随机选择时频资源块，遵从该子带对应的配置信息进行传输，也能达到覆盖增强的技术效果。例如终端1属于终端组1，其可以选择的子带有时频资源块1-1，时频资源块1-2，时频资源块2，时频资源块3，时频资源块4，终端1选择时频资源块4-1,进行上行传输，则选择使用时频资源块4-1对应的配置信息进行上行传输。
第二种：终端根据信道质量的测量结果，选择时频资源块进行上行传输。
此种方式中，终端可以根据信道质量测量结果，更有针对性的选择时频资源块进行上行免授权传输，因此更够获得更好的覆盖增强效果。
具体的，终端根据如下公式(1)进行信道质量测量：
SNR_target＝P_ul tx–Pathloss-P_noise  (1)
其中，SNR_target为目标信噪比；
Pathloss为路径损耗，其可以通过测量得到；此为本领域技术人员所熟知的技术手段，在此不再赘述；
P_noise为噪声功率；
P_ul_tx为上行传输功率；其通过如下公式(2)计算得到；
P_ul_tx＝P_ul_total-10*log(Num_RB*TTI bundlingsize)     (2)
其中，P_ul_total是上行传输允许的总发射功率；
因此，测得了Pathloss就能得到发送所需的RB的数目Num_RB*TTI bundlingsize
Num_RB*TTI bundlingsize＝10^(P_ul_total–Pathloss-P_noise)/10     (3)
在一种实现方式中，时频资源块为子带时，TTIbundling size取值为1。
终端根据上述公式(3)即可计算得到进行上行传输的时频资源块的数目，根据该时频资源块的数目，查找配置信息，选择该配置信息对应的时频资源块进行上行免授权传输。
此处，仅例举了通过计算上行传输的时频资源块数目选择对应的时频资源块的过程，本申请实施例还可以计算上行传输所需的功率，或者时频资源块的粒度，或者TTI bundling size指示或Repetition size指示等等参数，然后再选择相应的时频资源块，其计算公式按需设置，在此不再赘述。
第三种：终端基于之前数据传输成功率统计结果，选择时频资源块进行上行传输。
具体实现中，终端在进行初始传输时，可以随机选择一个时频资源块或者根据路径损耗(Pathloss)的值，选择一个合适的时频资源块来进行上行传输；
然后，当终端N次收到来自网络设备的NACK消息时，则触发选择更窄带宽的时频资源块来进行上行传输；当终端收到来自网络设备的ACK消息时，则可以选择更宽带宽的时频资源块来进行上行传输。此时，网络设备可以配置N的阈值，以便终端可以统计数据传输成功是否。
第四种：终端根据自己所需的发射功率，选择至少一个时频资源块进行上行传输。
例如终端在0001表示的第一个RB的起始位置上，采用长度为0001表示的长度1，用000表示的总功率的(1/2) o作为发射功率，以n4表示的长度为bundling size＝4的TTI bundling进行上行传输。
终端采取以上四种方式中任一种选择时频资源块后，按该时频资源块的对应的配置信息(例如覆盖增强参数或者时频资源块参数等)进行上行传输；在发送上行数据时，采用终端ID或者组内身份识别号(inner Group ID)进行CRC(Cyclic redundancy check，循环冗余校验)加扰。网络设备在进行终端检测时采用的导频(pilot)或参考信号(RS，reference Signal)或preamble(前导序列)是从对应的终端分组配置中选取。导频可以和终端一一对应，以便进行终端识别。
终端ID可以是C-RNTI(Cell-Radio Network Temporary Identity，小区无线网络临时标识)，也可以是组内身份识别号(inner Group ID)。C-RNTI在接入过程或切换过程进行配置；组内身份识别号由终端分组资源配置时提供。
终端进行上行传输后，基站可以通过盲解来进行新数据解调，即，在之前配置的时频资源块位置上进行数据处理；此时每个可能的时频资源块起始位置或索引号已经预先设定，因此基站只需要进行少量的尝试，而现有方式需要在任意的时频资源块位置使用多种可能的带宽进行尝试。
为进一步减少盲解带来的开销，可以考虑终端进行上行数据发送的同时发送用于携带资源选择结果的上行控制信令，把终端选择的传输时频资源块告知网络设备，例如用时频资源块的标识信息(例如时频资源块的起始位置或索引号)进行指示。进一步的，还可以上报终端在该时频资源块上传输所选定的其余参数配置，如TTI bundling size。为了区分不同终端发送的上述控制信令(即将该控制信令与终端关联)，可以和基站预先约定信令发送的时频资源，基站通过资源位置与终端关联。可选的，可以在上述上行控制信令携带终端ID，基站在收到该信令后识别终端和终端所用的时频资源块信息，并对应进行接收。
以上描述了网络设备将时频资源块配置为与终端组关联的基础上，终端根据配置信息进行上行传输的实现方式。下面将描述网络设备将子带配置为不与终端组关联的基础上，为每个时频资源块配置对应的配置信息的实现过程。
下面将从不同的信令承载方式描述以时频资源块为单位划分上行传输时频资源，具体的，该上行传输时频资源被划分为多个时频资源块；该时频资源块与终端组不相 关联的方式二中，本申请实施例的数据传输方法的实现过程。
信息1：针对多个终端的上行传输时频资源的时频资源块划分信息；时频资源块的配置信息中的标识信息，可以是信息1中时频资源块的起始位置或者索引号。
信息2：时频资源块对应的覆盖增强参数；
具体的，当网络设备针对多个终端的上行传输时频资源的时频资源块进行划分时，可以给每个时频资源块分配一个索引号，如表8所示：
表8
时频资源块 索引号
时频资源块1 1
时频资源块2 2
时频资源块3 3
时频资源块4 4
时频资源块5 5
时频资源块6 6
时频资源块7 7
时频资源块8 8
终端在选择时频资源块进行上行传输的时候，可以将其选择的时频资源块的索引号发送给网络设备，以便网络设备能准确检测。
若加上终端的映射关系，如表9所示：
表9
时频资源块 索引号 所属终端
时频资源块1 1 1
时频资源块2 2 2
时频资源块3 3 3
时频资源块4 4 4
时频资源块5 5 5
时频资源块6 6 6
时频资源块7 7 7
时频资源块8 8 8
包括时频资源块参数或者覆盖增强参数的信息2，在后续详细描述。
该信息2可以由网络设备进行***级的广播，即通过***消息发送至终端，也可在终端连接建立通过RRC信令或MAC CE进行配置。应理解的是，通过RRC信令进行承载的方式，其信令的开销更小，灵活程度更高。
下面将从不同的信令承载方式描述以时频资源块为单位划分上行传输时频资源，且不与终端组相关联的方式二中，本申请实施例的数据传输方法的实现过程。
应理解的是，下面的实施例主要描述了上行传输时频资源被划分为多个时频资源块具体是以子带形式时，其配置信息及其承载实现形式，该时频资源块进一步以时域为维度进行划分更小的时频资源块时，其起始位置，数目，长度等指示方式加上对应的时隙或者符号标识即可。
实施例九:以RRC信令承载时频资源块的配置信息
本实施例九与前述实施例一类似，定义一种新的RRC信令来携带配置信息，并由RRC连接建立消息“RRCConnectionSetup message”或者RRC连接重置消息“RRC ConnectionReconfiguration message”发送至终端。
其消息格式和字段含义如前述实施例一。另外，本实施例中，也可以同前述实施例五一样，用RRC信令承载包含时频资源块的粒度指示的配置信息，以及可以同前述实施例七那样，通过RRC信令承载包含TTI bundling size指示或Repetition size指示的配置信息；为了简洁，在此不再赘述。
实施例十：用MAC CE信令承载配置信息
本实施例十也是需要网络设备新定义一个MAC CE，并定义对应的MAC子头(sub-header)，其具体的消息格式和字段含义也如前实施例二；另外，本实施例中，也可以如前述实施例六那样，用MAC CE承载包含时频资源块的粒度指示的配置信息；以及可以同前述实施例八那样，通过MAC CE承载包含TTI bundling size指示或Repetition size指示的配置信息；为了简洁，在此不再赘述。
实施例十一：用***消息承载配置信息
本实施例中，也需要新增元素定义同RRC信令传输时的定义方式。
新增元素可添加在现有LTE协议定义的“RadioResourceConfigCommonSIB”中，由***消息传递给终端：
其消息格式表示如下：
Figure PCTCN2018080551-appb-000026
Figure PCTCN2018080551-appb-000027
本实施例也可以如前实施例四一样，利用***消息承载包含时频资源块粒度指示的配置信息，为了简洁，在此不再赘述。
前述实施例九至实施例十一分别从网络设备的角度，描述了在采用方式二，即将用于免授权传输的上行传输时频资源划分成多个时频资源块(未与终端组关联)的基础上，利用RRC，MAC CE，***消息，DCI承载配置信息的实现过程，其中配置信息携带的参数又分为功率控制参数，TTI bundling size指示或Repetition size指示，时频资源块的粒度，长度，时频资源块的索引号，时频资源块的起始位置或终止位置等等。
与前述子带与终端组相关联的实施例相似，本实施例中，终端在选择时频资源块的时候，同样有1、随机选择；2、根据信道质量测量结果选择；3、基于之前数据传输成功率的统计选择；4、基于发射功率需求进行选择等四种实现方式。
区别于前述时频资源块与终端组相关联的实施例，在时频资源块未与终端组关联的实现方式中，每个终端在进行上行免授权传输时，在发送上行数据时，需要在上行数据中增加终端的标识，例如用MAC CE或RRC信令携带终端标识。由于时频资源块对应的导频(pilot)或参考信号(RS，reference Signal)或preamble(前导序列)不是分配给固定的终端或终端组，无法区分终端。因此有必要在数据传输时显示的携带终端ID，以便网络设备在接收数据后区分终端或终端组并对上行数据的进一步处理或分发。类似的，数据加扰使用时频资源块对应的ID进行而不是终端ID。因为这一子带ID只与时频资源块对应，而不是分配给固定的终端或终端组。网络设备在进行终端检测时采用的导频(pilot)或参考信号(RS，reference Signal)或preamble(前导序列)是从对应的时频资源块配置中选取；网络设备用时频资源块的ID进行CRC处理，并根据上行数据中的终端ID进行上行数据的进一步处理或分发。
时频资源块的ID可以是C-RNTI(Cell-Radio Network Temporary Identity，小区无线网络临时标识)，也可以是新定义的能在小区内区分多个时频资源块的RNTI，并随着时频资源块的配置信息一起由网络设备发送至终端。
而终端ID可以是C-RNTI，或者是全局的用户标识，例如国际移动用户识别码 (International Mobile Subscriber Identification Number，简称为“IMSI”)、临时移动用户识别码(Temporary Mobile Subscriber Identity，简称为“TMSI”)等。
应理解，本发明实施例仅以C-RNTI、IMSI和TMSI为例对终端ID进行说明，但本申请并不限于此，用于确定该终端ID还可以采用其它用户标识。
同样的，其时频资源块ID或终端ID可以由SIB(system information block，***消息块)、RRC、MAC CE等信令进行承载。
前述实施例分别描述了网络设备将用于上行免授权传输的上行传输时频资源划分为多个时频资源块的基础上，网络设备如何配置对应的配置信息，以及终端如何选择时频资源块并使用配置信息进行上行免授权传输的各种实现方式。前述的配置信息中，时频资源块的子带的起始位置或长度都是通过字符进行表示的。例如对于字段“StartPoint”，其取值为0001表示时频资源块的起始位置是第一个RB；0010表示时频资源块的起始位置是第二个RB等等；对于字段“Length”，其取值为0001代表长度1，0001代表长度2，0010代表长度4，以此类推。
在另一种实现方式中，不同的子带对应的配置信息还可以通过导频图案或导频序列进行表示，下面将详细描述。需要说明的是，时频资源块进一步以时域为维度进行划分更小的时频资源块时，其起始位置，数目，长度等指示方式加上对应的时隙或者符号标识即可，在此不再赘述。
终端在进行数据传输时，需要同时发送导频以便信道估计，并用于数据解调。随着带宽的变化，协议在兼顾效率和性能的情况下会定义不同的导频图案。
具体的：
时频资源块以子载波为粒度，定义新的导频图案，如图16所示的1个子载波时的导频图案、2个子载波时的导频图案、4个子载波时的导频图案，此处仅为举例。
在对时频资源块配置对应的配置信息时，只需要按序的指示各个时频资源块所用的导频图案，就能获取时频资源块的索引号或者起始位置，具体如下实施例十二。
实施例十二：在RRC信令中用导频图案表示时频资源块的起始位置
本实施例如前述实施例一，定义一种新的RRC信息元素(Radio resource control information element)，并在放RRC message–RRCConnectionSetup中传递。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000028
Figure PCTCN2018080551-appb-000029
其中字段含义如下：
Figure PCTCN2018080551-appb-000030
应理解的是，该消息格式描述了上行传输时频资源被划分为多个时频资源块具体是以子带形式时的实现形式，该时频资源块以时域为维度进行划分更小的时频资源块时，其索引号，起始位置，数目，长度，终止位置等指示方式加上对应的时隙或者符号标识即可。
另外，本实施例中，也可以同前述实施例七那样，通过RRC信令承载包含TTI bundling size指示或Repetition size指示的配置信息；为了简洁，在此不再赘述。
上述实施例仅以RRC信令承载配置信息为例，其包含导频图案的配置信息还可以通过MAC CE，DCI或者***消息进行承载。
本申请实施例中，还可以定义新的导频图案表示时频资源块的粒度(Width)，该粒度可以为子载波，或者RB或者RBG。如图17所示的子带粒度为子载波的导频图案、子带粒度为RB的导频图案、时频资源块粒度为RBG(包含3个RB)的导频图案，此处仅为举例。
在对时频资源块配置对应的配置信息时，只需要按序的指示导频图案，就能获取子带的粒度，具体如下实施例十三。
实施例十三：在RRC信令中用导频图案表示时频资源块的粒度
本实施例如前述实施例一，定义一种新的RRC信息元素(Radio resource control information element)，并在放RRC message–RRCConnectionSetup中传递。
以时频资源块为子带为例，其消息格式表示如下：
Figure PCTCN2018080551-appb-000031
Figure PCTCN2018080551-appb-000032
其中字段含义如下：
Figure PCTCN2018080551-appb-000033
另外，本实施例中，也可以同前述实施例七那样，通过RRC信令承载包含TTI bundling size指示或Repetition size指示的配置信息；为了简洁，在此不再赘述。
除了子带的索引号，起始位置、终止位置，数目以及时频资源块的粒度可以采用导频图案表示，其他字段的表示方式与前述实施例一至实施例十二类似，为了简洁，在此不再赘述。
在另一种实现方式中，还可以通过导频序列表示时频资源块的起始位置或数目；例如：
Figure PCTCN2018080551-appb-000034
其中
Figure PCTCN2018080551-appb-000035
是ZC序列长度，n表示序列元素编号，q为ZC序列的根(root)。不同的根对应不同的ZC序列。网络设备通过检测终端发送了哪个序列判断对应的时频资源块的起始位置或数目。
在网络设备以上述导频图案或者导频序列的方式表示时频资源块的配置信息时，终端侧接收到携带导频图案或导频序列的配置信息时，选择相应的时频资源块进行传输，其方式如前述实施例相似，同样有1、随机选择；2、根据信道质量测量结果选择；3、基于之前数据传输成功率的统计选择；4、基于发射功率需求进行选择等四种实现方式。为了简洁，在此不再赘述。
应理解，导频序列为ZC(Zadoff-Chu)序列仅为举例；又例如，该导频序列还可以为状态检测参考信号(Activity Detection Reference Signal，简称为“ADRS”)，伪 噪声序列(Pseudo-Noise Sequence)，也称之为PN序列，M序列，Walsh码等，但本发明实施例并不限于此。
还应理解，在本发明实施例中，如果导频序列使用Zadoff-Chu序列，则映射到同一子带的终端可以通过循环移位值和根编号进行区分；如果导频序列使用M序列，则映射到同一子带的终端可以通过循环移位值进行区分，即映射到同一子带的终端的导频序列对应不同的循环移位值。

实施本申请提供的网络设备和终端，由于网络设备为终端预分配的上行传输时频资源划分为多个以时频资源块为单位的上行传输时频资源，因此终端可以选择更窄带宽的时频资源进行上行传输，提高了终端的发射功率；进一步的，网络设备还为每一个时频资源块配置了配置信息，该配置信息可以携带时频资源块参数或者覆盖增强参数，或者两个参数都携带，因此，终端选择了进行上行传输的时频资源块之后，根据对应配置信息进行上行传输，可以进一步的提高发射功率；而网络设备也能根据配置信息在正确的时频资源块上进行解调，从而提高解调的效率，避免产生处理时延。
