Description

通信的方法、网络设备和终端设备
本申请要求于2018年01月12日提交中国专利局、申请号为201810030620.8、申请名称为“通信的方法、网络设备和终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，特别涉及一种通信的方法、网络设备和终端设备。
背景技术
物理资源块(physical resource block，PRB)绑定(physical resource block bundling，PRB bundling)是一种用于提高信道估计性能的技术。PRB绑定是将连续的多个PRB绑定在一起联合处理，网络设备可以对该多个PRB(也可以称为预编码资源块组(Precoding Resource block Group，PRG))采用相同预处理方式(包括波束赋形和预编码)；终端设备可以联合该多个PRB进行信道估计。终端设备基于多个PRB进行联合信道估计时，可以减少信道估计的外插计算，提高信道估计的准确性。
在不同场景(信道环境)中，综合考虑信道估计增益，终端实现复杂度，赋形增益和调度情况，最优的PRB绑定大小可以是不同的。
现有协议中规定了PRB绑定时，网络设备默认采用唯一的方法确定预编码资源块组的大小，以及终端设备默认采用唯一的方法确定资源块绑定的大小。然而现有PRB应用中采用一种默认方法确定预编码资源块组大小或资源块绑定的大小，导致现有的PRB绑定应用不够灵活，难以满足不同PRB绑定大小取值时的需求。
发明内容
本申请提供一种通信的方法、网络设备和终端设备，该方法能够满足不同PRB绑定大小取值时的需求。
第一方面，提供了一种通信的方法，该方法包括：网络设备根据资源绑定粒度的取值确定终端设备对应的调度资源中的至少一个预编码资源块组，所述资源绑定粒度的取值的类型为第一类取值和第二类取值中的一种，所述第一类取值和所述第二类取值对应的预编码资源块组的确定方法不同；所述网络设备通过所述至少一个预编码资源块组向所述终端设备进行数据传输。
应理解，本申请实施例中，资源绑定粒度也可以称为资源绑定组大小，该资源绑定粒度可以为物理资源块绑定(physical resource block bundling，PRB bundling)粒度或者预编码资源块组(Precoding Resource block Group，PRG)粒度，本申请实施例并不限于此。其中，PRG粒度可以表示发送端采用相同预编码的连续的PRB的个数，PRB绑定粒度可以表示接收端进行联系信道估计的PRB的个数。
本申请实施例中，PRG可以与PRB绑定组对应，在不同通信设备侧资源绑定的叫法可能不同，但其含义可以相同。例如，通常在发送端(例如，网络设备)侧资源绑定粒度称为PRG，且发送端在同一PRG中传输的数据采用相同的预编码；在接收端(例如，终端设备)侧资源绑定粒度称为PRB绑定组，且接收端对同一PRB绑定组中的传输的数据进行联合信道估计。
需要说明的是，PRG与PRB绑定组两者可以通用，例如，发送端侧和接收端侧的资源绑定均可以指PRG，或者，发送端侧和接收端侧的资源绑定均可以指PRB绑定组，本申请实施例并不限于此。
应理解，网络设备侧的PRG可以与终端设备侧的PRB绑定组相对应。针对同一个资源绑定粒度取值，网络设备侧确定PRG的方法和终端设备侧确定PRB绑定组的方法可以相同。但在同一侧，即在网络设备侧或终端设备侧，资源绑定粒度取值为第一类取值和第二类取值时对应的确定PRG的方法或PRB绑定组的方法不同。
因此，本申请实施例通过根据资源绑定粒度的取值的不同采用不同的方法确定调度资源中的至少一个预编码资源块组，解决了现有技术中的问题，能够满足不同资源绑定粒度取值的需求。
结合第一方面，在第一方面的某些实现方式中，所述资源绑定粒度的取值为所述第一类取值，
所述网络设备根据所述资源绑定粒度的取值确定所述终端对应的调度资源中的至少一个预编码资源块组，包括：
所述网络设备根据资源绑定粒度的取值和所述调度资源在系统最大可用带宽中的位置确定所述调度资源中的至少一个预编码资源块组。
结合第一方面，在第一方面的某些实现方式中，所述网络设备根据资源绑定粒度的取值和所述调度资源在系统最大可用带宽中的位置确定所述调度资源中的至少一个预编码资源块组，包括：
所述网络设备根据以下公式确定所述调度资源中的第一个预编码资源块组:
PRG first＝P-NmodP
其中，PRG first表示所述第一个预编码资源块组包括所述调度资源中的前PRG first个资源块，P表示所述资源绑定粒度的取值，N表示所述调度资源中第一个物理资源块PRB在所述系统最大可用带宽中索引，NmodP表示N除以P的余数；
所述网络设备根据以下公式确定所述调度资源中的最后一个预编码资源块组：
PRG 1ast＝(N+L)modP
其中，PRG last表示所述最后一个预编码资源块组包括所述调度资源中的最后PRG last个资源块，L表示所述调度资源中PRB的个数，(N+L)modP表示N+L整除P的余数；
所述网络设备确定所述调度资源中的其他预编码资源块组包括所述调度资源中的资源绑定粒度的取值个连续的资源块。
结合第一方面，在第一方面的某些实现方式中，所述资源绑定粒度的取值为所述第二类取值，
所述网络设备根据所述资源绑定粒度的取值确定所述终端对应的调度资源中的至少一个预编码资源块组，包括：
所述网络设备根据所述资源绑定粒度的取值确定所述调度资源为同一预编码资源块组。
结合第一方面，在第一方面的某些实现方式中，所述第一类取值包括2和4，所述第二类取值包括所述终端设备连续调度带宽的大小。
换句话说，在资源绑定粒度的取值为第二类取值时，网络设备无需使用第一类取值对应的确定方法，即按照资源绑定粒度的取值和调度资源在系统最大可用带宽中的位置确定预编码资源块组。网络设备可以直接将所述调度资源确定为同一预编码资源块组。
因此，本申请实施例在资源绑定粒度的取值为第二类取值时，网络设备摒弃了上述通过划分资源的方式确定预编码资源块组的方法，而是直接将调度资源作为同一PRG，满足了在资源绑定粒度为第二取值时，网络设备对整个调度资源进行相同预编码的需求，能够避免现有技术中的问题。
第二方面，提供了一种通信的方法，该方法包括：
终端设备根据资源绑定粒度的取值确定所述终端设备对应的调度资源中的至少一个资源块绑定组，所述资源绑定粒度的取值为第一类取值和第二类取值中的一种，所述第一类取值和所述第二类取值对应的资源块绑定组的确定方法不同；所述终端设备通过所述至少一个资源块绑定组接收来自网络设备的数据传输。
因此，本申请实施例终端设备通过根据资源绑定粒度的取值的不同采用不同的方法确定调度资源中的至少一个资源块绑定组，解决了现有技术中的问题，能够满足不同资源绑定粒度取值的需求。
应理解，第二方面描述的终端设备侧的方法与第一方面描述网络设备的方法相对应，终端设备侧的方法可以参考网络设备侧的描述，避免重复，此处适当省略详细描述。
结合第二方面，在第二方面的某些实现方式中，所述资源绑定粒度的取值为所述第一类取值，
所述终端设备根据所述资源绑定粒度的取值确定所述终端设备对应的调度资源中的至少一个资源块绑定组，包括：
所述终端设备根据所述资源绑定粒度的取值和所述调度资源在系统最大可用带宽中的位置确定所述调度资源中的至少一个资源块绑定组。
结合第二方面，在第二方面的某些实现方式中，所述终端设备根据所述资源绑定粒度的取值和所述调度资源在系统最大可用带宽中的位置确定所述调度资源中的至少一个资源块绑定组，包括：
所述终端设备根据以下公式确定所述调度资源中的第一资源块绑定组:
PRBbundling first＝P-NmodP
其中，PRBbundling first表示所述第一个资源块绑定组包括所述调度资源中的前PRBbundling first个资源块，P表示所述资源绑定粒度的取值，N表示所述调度资源中第一个PRB在所述系统最大可用带宽中的索引，NmodP表示N整除P的余数；
所述终端设备根据以下公式确定所述调度资源中的最后一个资源块绑定组：
PRBbundling last＝(N+L)modP
其中，PRBbundling last表示所述最后一个资源块绑定组包括所述调度资源中的最后PRBbundling last个资源块，L表示所述调度资源中PRB的个数，(N+L)modP表示N+L 除以P的余数；
所述终端设备确定所述调度资源中的其他资源块绑定组包括所述调度资源中的资源绑定粒度的取值个连续的资源块。
结合第二方面，在第二方面的某些实现方式中，所述资源绑定粒度的取值为所述第二类取值，
所述终端设备根据所述资源绑定粒度的取值确定所述终端对应的调度资源中的至少一个资源块绑定组，包括：
所述终端设备根据所述资源绑定粒度的取值确定所述调度资源为同一资源块绑定组。
结合第二方面，在第二方面的某些实现方式中，所述第一类取值包括2和4，所述第二类取值包括所述终端设备连续调度带宽的大小。
第三方面，提供了一种网络设备，所述网络设备包括用于执行第一方面或第一方面任一种可能实现方式中的方法的各个模块或单元。
第四方面，提供了一种终端设备，所述终端设备包括用于执行第二方面或第二方面任一种可能实现方式中方法的各个模块或单元。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例可应用于各种通信系统，因此，下面的描述不限制于特定通信系统。例如，本申请实施例可以应用于全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，WiFi)以及下一代通信系统，即第五代(5th generation，5G)通信系统，例如，新空口(new radio，NR)系统。
本申请实施例中，网络设备可以是全球移动通讯(global system of mobile communication，GSM)或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的基站(nodeB，NB)，还可以是长期演进(long term evolution，LTE)中的演进型基站(evolutional node B，eNB/eNodeB)，或者中继站或接入点，或者未来5G网络中的网络侧设备，例如，NR系统中传输点(TRP或TP)、NR系统中的基站(gNB)、NR系统中的射频单元，如远端射频单元、5G系统中的基站的一个或一组(包括多个天线面板)天线面板等。不同的网络设备可以位于同一个小区，也可以位于不同的小区，具体的在此不做限定。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和分布式单元(Distributed Unit，DU)。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
本申请实施例中，终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、无人机设备以及未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
作为示例而非限定，在本发明实施例中，该终端设备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、智能首饰等。
本申请实施例可以适应于上述任意通信系统，例如，本申请实施例可以适用于LTE系统以及后续的演进系统如5G等，或其他采用各种无线接入技术的无线通信系统，如采用码分多址，频分多址，时分多址，正交频分多址，单载波频分多址等接入技术的系统，尤其适用于需要信道信息反馈和/或应用二级预编码技术的场景，例如应用大规模阵列天线(Massive Multiple-Input Multiple-Output，Massive MIMO)技术的无线网络、应用分布式天线技术的无线网络等。
图1是本申请实施例可应用的通信系统的场景示意图。如图1所示，该通信系统100包括网络侧设备102，网络侧设备102可包括多个天线组。每个天线组可以包括多个天线，例如，一个天线组可包括天线104和106，另一个天线组可包括天线106和110，附加组可包括天线112和114。图1中对于每个天线组示出了2个天线，然而可对于每个组使用更多或更少的天线。网络侧设备102可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络侧设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络侧设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、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100上通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路116向终端设备116发送信息，并通过反向链路120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(frequency division duplex，FDD)系统中，例如，前向链路116 可利用与反向链路120所使用的不同频带，前向链路124可利用与反向链路126所使用的不同频带。
再例如，在时分双工(time division duplex，TDD)系统和全双工(full duplex)系统中，前向链路116和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每组天线和/或区域称为网络侧设备102的扇区。例如，可将天线组设计为与网络侧设备102覆盖区域的扇区中的终端设备通信。在网络侧设备102通过前向链路116和124分别与终端设备116和122进行通信的过程中，网络侧设备102的发射天线可利用波束成形来改善前向链路116和124的信噪比。此外，与网络侧设备通过单个天线向它所有的终端设备发送信号的方式相比，在网络侧设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络侧设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
此外，该通信系统100可以是公共陆地移动网络PLMN网络或者设备对设备(device to device，D2D)网络或者机器对机器(machine to machine，M2M)网络或者其他网络，图1仅为便于理解而示例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
图2示出了数据通过正交频分复用(orthogonal frequency division multiplexing，OFDM)符号发送之前发送端(例如网络设备)所进行的数据处理过程的主要步骤。如图2所示，
来自上层(例如，媒体接入控制(media access control，MAC)层)的业务流经过信道编码之后的得到的码字经过加扰、调制、层映射后映射到一个或多层，然后经过预编码处理、资源单元映射，最后将调制后的符号通过天线端口发送出去。
相应地，接收端(例如终端设备)可以进行解调数据。具体的上述各个数据处理过程可以参见现有标准中的描述。
为了提高系统性能，收发两端可以采用资源绑定(例如，PRB绑定)技术。具体而言，PRB绑定是将连续的多个PRB绑定在一起联合处理，发送端(例如网络设备)可以对多个PRB(也可以称为PRG)采用相同预处理方式(包括波束赋形和预编码)，接收端(例如，终端设备)可以联合该多个PRB进行信道估计，以对接收到的数据进行解调。
前文已说明，在不同场景(信道环境)中，综合考虑信道估计增益，终端实现复杂度，赋形增益和调度情况，最优的PRB绑定大小是不同的。现有标准中，在NR系统中已同意PRB绑定可配置，当前可选的配置值可以包括2、4以及连续调度带宽等。
然而在现有PRB绑定应用中收发两端均采用一种默认方法确定预编码资源块组大小或资源块绑定的大小，导致现有的PRB绑定应用不够灵活，难以满足不同PRB绑定大小取值时的需求。
例如，在PRB绑定取值为连续调度带宽时，网络侧和终端设备会假设整个连续调度资源为同一预编码资源块组，即整个调度资源采用相同的预编码，然而，按照现有协议默认确定预编码资源块组的方法可能会确定出多个预编码资源块组。
鉴于上述问题，本申请实施例巧妙地提出一种通信的方法，具体的，本申请实施例摒弃了仅采用默认的一种方法确定预编码资源块组的方案，而是根据资源绑定粒度的取值的不同采用不同的方法确定调度资源中的至少一个预编码资源块组或者至少一个资源块绑定，解决了现有技术中的问题，能够满足不同资源绑定粒度取值的需求。
以下，为了便于理解和说明，作为示例而非限定，以将本申请的通信的方法在通信系统中的执行过程和动作进行说明。
图3是根据本发明一个实施例的通信的方法示意性流程图。如图3所示的方法可以应用于上述任一通信系统中。具体的，如图3所示从系统的角度描述的通信的方法300包括：
310，网络设备根据资源绑定粒度的取值确定所述终端对应的调度资源中的至少一个预编码资源块组。
其中，所述资源绑定粒度的取值的类型为第一类取值和第二类取值中的一种，所述第一类取值和所述第二类取值对应的预编码资源块组的确定方法不同。
事实上，资源绑定粒度的取值的类型可以是多类取值之中的一种，各类取值对应的预编码资源块组的确定方法可以不同，所述多类取值至少包含上述第一类取值和第二类取值。
在根据资源绑定粒度的取值确定所述终端对应的调度资源中的至少一个预编码资源块组的过程中，需要确定预编码资源块组的确定方法，这样才可以根据资源绑定粒度的取值和预编码资源块组的确定方法，来确定上述至少一个预编码资源块组。在具体实现过程中，可以根据资源绑定粒度的取值来确定预编码资源块组的确定方法。例如，资源绑定粒度的取值、取值的类型与预编码资源块组的确定方法之间可以存在如下对应关系：
表1
资源绑定粒度的取值 取值的类型 预编码资源块组的确定方法
2 第一类取值 第一种方法
4 第一类取值 第一种方法
调度带宽 第二类取值 第二种方法
… … …
在上述表1中，当资源绑定粒度的取值为2个或者4个PRB时，这两个取值属于第一类取值，预编码资源块组的确定方法应采用第一种方法；当资源绑定粒度的取值为调度带宽时，该调度带宽属于第二类取值，预编码资源块组的确定方法为第二种方法。
由表1可知，资源绑定粒度的取值、取值的类型和预编码资源块组的确定方法三者之间存在对应关系。在确定预编码资源块组的确定方法时，可以根据资源绑定粒度的取值确定取值的类型，再根据取值的类型确定对应的预编码资源块组的确定方法；也可以根据资源绑定粒度的取值直接确定预编码资源块组的确定方法。由此可见，可以根据资源绑定粒度的取值来确定预编码资源块组的确定方法。事实上，在具体实现过程中，可以采用各种 方法，来根据资源绑定粒度的取值来确定预编码资源块组的确定方法，本发明实施例对具体方法不做限定。
相应地，作为另一实施例，终端设备根据资源绑定粒度的取值确定所述终端对应的调度资源中的至少一个资源块绑定组。
具体而言，以传输下行数据为例，网络设备可以向终端设备发送指示信息，该指示信息指示资源绑定粒度，例如，网络设备通过无线资源控制(radio resource control，RRC)信令或者下行控制信息(downlink control information，DCI)发送该指示信息。例如，网络设备可以通过RRC信令指示该资源绑定粒度的具体取值，例如取值为2、4和终端设备连续调度带宽。或者，网络设备可以通过RRC信令指示该资源绑定粒度的取值范围，例如，该取值范围为2、4和终端设备连续调度带宽三者中的两个，并通过DCI指示该资源绑定粒度为该取值范围中的其中一个取值。或者，网络设备可以通过RRC信令指示该资源绑定粒度的取值范围，例如，该取值范围包括2、4和终端设备连续调度带宽，然后通过DCI和系统配置参数指示该资源绑定粒度的具体取值，本申请实施例并不限于此。之后，网络设备可以根据该资源绑定粒度的具体取值使用与该取值对应的方法确定调度资源中的至少一个PRG；相应地，终端设备可以根据该资源绑定粒度的具体取值使用与该取值对应的方法确定调度资源中的至少一个PRB绑定组。
应理解，本申请实施例中，网络设备根据资源绑定粒度的取值确定调度资源中的至少一个PRG可以理解为网络设备根据资源绑定粒度的取值确定调度资源中的至少一个PRG的大小和网络设备确定调度中的至少一个PRG的资源位置二者之中的至少一种；类似地，终端设备根据资源绑定粒度的取值确定调度资源中的至少一个PRB绑定组可以理解为终端设备根据资源绑定粒度的取值确定调度资源中的至少一个PRB绑定组的大小和终端设备确定调度资源中的至少一个PRB绑定组的资源位置二者之中的至少一种，本申请实施例并不限于此。
可选地，该终端设备对应的调度资源可以为网络设备通过信令例如DCI信令配置的。例如，该终端设备对应的资源(或者称为调度带宽)为网络设备配置的多个带宽部分(Bandwidth part，BWP)中的其中一个BWP，或者一个BWP中的一部分频带，例如多个子带，本申请实施例并不限于此。带宽部分可以理解为一段连续的频带，该频带包含至少一个连续的子带，每个带宽部分可以对应一组系统参数(numerology)，包括例如但不限于，子载波间隔(Subcarrier spacing)和循环前缀(Cyclic Prefix，CP)等，不同带宽部分可以对应不同的系统参数。作为可选的，在同一个传输时间间隔(Transmission Time Interval，TTI)内，在多个带宽部分之中，可以仅有一个带宽部分可用，其他带宽部分不可用。有关带宽部分的定义可以参考现有技术，例如但不限于针对NR的各种提案。随着技术的不断发展，上述定义也有可能发生变化。
应理解，本申请实施例中，资源绑定粒度也可以称为资源绑定大小，该资源绑定粒度可以为物理资源块绑定(physical resource block bundling，PRB bundling)粒度(也可以称为资源块绑定组)或者预编码资源块组(Precoding Resource block Group，PRG)粒度(也可以称为预编码资源块组)，本申请实施例并不限于此。其中，PRG粒度可以表示发送端采用相同预编码的连续的PRB的个数，PRB绑定粒度可以表示接收端进行联合信道估计的PRB的个数。
本申请实施例中，PRG可以与PRB绑定组对应，在不同通信设备侧资源绑定的叫法可能不同，但其含义可以相同。例如，通常在发送端(例如，网络设备)侧资源绑定粒度称为PRG，且发送端在同一PRG中传输的数据采用相同的预编码；在接收端(例如，终端设备)侧资源绑定粒度称为PRB绑定组，且接收端对同一PRB绑定组中的传输的数据进行联合信道估计。
需要说明的是，PRG与PRB绑定组两者可以通用，例如，发送端侧和接收端侧的资源绑定均可以指PRG，或者，发送端侧和接收端侧的资源绑定均可以指PRB绑定组，本申请实施例并不限于此。
应理解，网络设备侧的PRG可以与终端设备侧的PRB绑定组相对应。针对同一个资源绑定粒度取值，网络设备侧确定PRG的方法和终端设备侧确定PRB绑定组的方法可以相同。但在同一侧，即在网络设备侧或终端设备侧，资源绑定粒度取值为第一类取值和第二类取值时对应的确定PRG的方法或PRB绑定组的方法不同。
因此，本申请实施例通过根据资源绑定粒度的取值的不同采用不同的方法确定调度资源中的至少一个PRG或者PRB绑定组，解决了现有技术中的问题，能够满足不同资源绑定粒度取值的需求。
可选地，作为一个实施例，所述第一类取值包括2和4，所述第二类取值包括终端设备连续调度带宽的大小(也可以称为调度带宽)即将整个调度带宽作为一个PRG或者PRB绑定组。应理解，本申请实施例中第一类取值和第二类取值还可以包括其他值，本申请实施例并不限于此。
下面分情况详细描述网络设备在资源绑定粒度分别为第一类取值和第二类取值时，具体的确定预编码资源块组的方法；以及终端设备在资源绑定粒度分别为第一类取值和第二类取值时，具体的确定资源块绑定组的方法。
情况一：作为一个实施例，在资源绑定粒度的取值为第一类取值时，例如，为2或4时，网络设备可以根据资源绑定粒度的取值和所述调度资源在系统最大可用带宽中的位置确定所述调度资源中的至少一个预编码资源块组。
具体地，以资源绑定里的取值(例如，2个PRB或者4个PRB)为单位，对系统最大可用带宽(如分量载波(component carrier))进行划分。具体的，从系统最大可用带宽中的第一个PRB(频段最低或最高的PRB)开始以该资源绑定粒度的取值为单位按照频率由低到高的顺序(对应第一个PRB为频段最低的PRB)或者由高到低的顺序(对应第一个PRB为频段最高的PRB)进行划分确定各个资源块组，其中，该调度资源(例如，BWP)中的起始PRB可能为与某个资源块组的起始PRB不重合。这种情况下，该调度资源中的第一个预编码资源块组包括的PRB个数和最后一个预编码资源块组包括的PRB个数可能不等于该资源绑定粒度的取值。
具体的，作为另一实施例，所述网络设备可以根据以下公式确定所述调度资源中的第一个预编码资源块组:
PRG first＝P-NmodP
其中，PRG first表示所述第一个预编码资源块组包括所述调度资源中的前PRG first个资源块，P表示所述资源绑定粒度的取值，N表示所述调度资源中第一个物理资源块PRB在所述系统最大可用带宽中的索引(也可以称为编号)，NmodP表示N除以P的余数；
所述网络设备根据以下公式确定所述调度资源中的最后一个预编码资源块组：
PRG 1ast＝(N+L-1)modP
其中，PRG last表示所述最后一个预编码资源块组包括所述调度资源中的最后PRG last个资源块，L表示所述调度资源中PRB的个数，(N+L-1)modP表示N+L整除P的余数；
所述网络设备确定所述调度资源中的其他预编码资源块组(即调度资源中去除第一个预编码资源块组和最后一个预编码资源块组后剩余的其他预编码资源块组，该其他预编码资源块组也可以称为中间预编码资源块组)包括所述调度资源中的资源绑定粒度的取值个连续的资源块。
举例而言，如图4所示，假设资源绑定粒度的取值4，系统最大可用带宽包括36个PRB，即由低频段至高频段的第0个PRB至第35个PRB。调度资源包括该系统最大可用带宽中的第13个PRB至第26个PRB，即调度资源的长度L为16。根据上文描述的方法，可知，P＝4，N＝13，L＝16。根据上述确定预编码资源块组的方法可以得出该调度资源包括5个预编码资源块组，其中，由于该调度资源中的起始PRB与系统最大可用带宽中的第4个资源块组的起始PRB不重合。因此，该调度资源中的第1个预编码资源块组(PRG)包括的PRB个数和最后1个预编码资源块组包括的PRB个数不等于该资源绑定粒度的取值4。其中，第1个预编码资源块组包括3个PRB，第2至第4个预编码资源块组包括4个PRB，第5个预编码资源块组包括1个PRB。具体的，第1个预编码资源块组包括系统最大可用带宽中的第13至第15个PRB，第2预编码资源块组包括第16至第19个PRB，第3预编码资源块组包括第20至第23个PRB，第4预编码资源块组包括第24至第27个PRB，第5预编码资源块组包括第28个PRB。
情况二：作为一个实施例，在资源绑定粒度的取值为第二类取值时，例如，为终端设备连续调度带宽的大小时，所述网络设备可以根据所述资源绑定粒度的取值确定所述调度资源为同一预编码资源块组，即第二种方法为将整个调度资源(或者称为调度带宽)作为同一预编码资源块组。
换句话说，在资源绑定粒度的取值为第二类取值时，网络设备无需按照上述情况一汇总的方法，即按照资源绑定粒度的取值和调度资源在系统最大可用带宽中的位置确定预编码资源块组。网络设备可以直接将所述调度资源确定为同一预编码资源块组。
举例而言，如图5所示，系统最大可用带宽包括36个PRB，即第0个PRB至第35个PRB，调度资源包括该系统最大可用带宽中的第13个PRB至第28个PRB，那么在资源绑定粒度的取值为第二类取值(例如，连续调度带宽的大小)时，网络设备可以直接确定该调度资源中的所有PRB即第13个PRB至第28个PRB为一个预编码资源块组。
因此，本申请实施例在资源绑定粒度的取值为第二类取值时，网络设备摒弃了上述通过划分资源的方式确定预编码资源块组的方法，而是直接将调度资源作为同一PRG，满足了在资源绑定粒度为第二取值时，网络设备对整个调度资源进行相同预编码的需求，能够避免现有技术中的问题。
上文描述了网络设备在资源绑定粒度的取值为第一类取值和第二类取值时确定预编码资源块组的方法。下面分情况描述终端设备在资源绑定粒度的取值为第一类取值和第二类取值时确定资源块绑定的方法。
应理解，由于终端设备确定资源块绑定的方法与网络设备确定预编码资源块组的方法对应，因此，为避免重复，适当省略详细描述终端设备侧确定资源块绑定的方法。
情况一：作为一个实施例，所述资源绑定粒度的取值为所述第一类取值，所述终端设备根据所述资源绑定粒度的取值和所述调度资源在系统最大可用带宽中的位置确定所述调度资源中的至少一个资源块绑定组。
具体而言，所述终端设备根据以下公式确定所述调度资源中的第一资源块绑定组:
PRBbundling first＝P-NmodP
其中，PRBbundling first表示所述第一个资源块绑定组包括所述调度资源中的前PRBbundling first个资源块，P表示所述资源绑定粒度的取值，N表示所述调度资源中第一个PRB在所述系统最大可用带宽中的索引，NmodP表示N整除P的余数；
所述终端设备根据以下公式确定所述调度资源中的最后一个资源块绑定组的大小：
PRBbundling last＝(N+L)modP
其中，PRBbundling last表示所述最后一个资源块绑定组包括所述调度资源中的最后PRBbundling last个资源块，L表示所述调度资源中PRB的个数，(N+L)modP表示N+L除以P的余数；
所述终端设备确定所述调度资源中的其他资源块绑定组包括所述调度资源中的资源绑定粒度的取值个连续的资源块。
情况二：作为一个实施例，该资源绑定粒度的取值为所述第二类取值，
所述终端设备根据所述资源绑定粒度的取值确定所述调度资源为同一资源块绑定组。
因此，本申请实施例在资源绑定粒度的取值为第二类取值时终端设备摒弃了上述通过划分资源的方式确定资源块绑定组的方法，而是直接将调度资源作为同一资源块绑定组，满足了在资源绑定粒度为第二取值时，终端设备对整个调度资源联合信道估计的需求，能够避免现有技术中的问题。
320，网络设备通过该至少一个预编码资源块组向终端设备进行数据传输。
相应的，所述终端设备通过所述至少一个资源块绑定接收来自网络设备的数据传输。
具体而言，网络设备根据确定预编码资源块组，对同一预编码资源块组中的数据进行相同的预编码(例如使用相同的预编码矩阵进行预编码)，然后经过如图2描述的预编码之后的处理过程后向终端设备进行数据传输，对应的，终端设备根据确定的资源块绑定组，对同一资源块绑定组中的数据进行联合信道估计进行解码，最终获取网络设备发送的数据。
因此，本申请实施例通过根据资源绑定粒度的取值的不同采用不同的方法确定调度资源中的至少一个PRG或者PRB绑定组，解决了现有技术中的问题，能够满足不同资源绑定粒度取值的需求。
应理解，上文中图1至图5的例子，仅仅是为了帮助本领域技术人员理解本发明实施例，而非要将本发明实施例限于所例示的具体数值或具体场景。本领域技术人员根据所给出的图1至图5的例子，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本发明实施例的范围内。

可选地，作为一个实施例，处理单元用于根据资源绑定粒度的取值确定终端设备对应的调度资源中的至少一个预编码资源块组，所述资源绑定粒度的取值为第一类取值和第二类取值中的一种，所述第一类取值和所述第二类取值对应的预编码资源块组的确定方法不同；所述收发单元用于通过所述至少一个预编码资源块组向所述终端设备进行数据传输。
因此，本申请实施例通过根据资源绑定粒度的取值的不同采用不同的方法确定调度资源中的至少一个PRG，解决了现有技术中的问题，能够满足不同资源绑定粒度取值的需求。
可选地，作为另一实施例，所述资源绑定粒度的取值为所述第一类取值，

处理单元72可用于执行该存储器存储的指令，以控制收发单元71接收信号和/或发送信号，完成上述方法实施例中终端设备的功能。作为一种实现方式，收发单元71的功能可以考虑通过收发电路或者收发的专用芯片实现。
