Description

一种通信方法及装置 技术领域
本公开涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
随着新一代AR/VR、车车通信等新型互联网应用的不断涌现，对无线通信技术提出了更高的要求，驱使无线通信技术的不断演进以满足应用的需求。当下，蜂窝移动通信技术正在处于新一代技术的演进阶段。新一代技术的一个重要特点就是要支持多种业务类型的灵活配置。由于不同的业务类型对于无线通信技术有不同的要求，如增强移动宽带(enhanced Mobile Broad Band，eMBB)业务类型主要的要求侧重在大带宽，高速率等方面。超高可靠与低时延通信(Ultra Reliable Low Latency Communication，URLLC)业务类型主要的要求侧重在较高的可靠性以及低的时延方面；海量机器类通信(massive Machine Type Communication，mMTC)业务类型主要的要求侧重在大的连接数方面。因此新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。
为支持多种业务类型的传输，网络覆盖的性能是至关重要的。网络部署的密集的情况下，覆盖的性能会比较好，但是会增加运营商的成本。网络部署稀疏的情况下，覆盖的性能比较差。
为提高网络覆盖性能，相关技术中采用重复传输方式增强网络覆盖性能。例如，通过时域上的重复传输，或者通过频域上跳频来获得频域上的分集增益，提高上行覆盖的性能。但是时域上重复传输的方法会导致频谱资源的利用率会比较低，另外也会带来额外的时延。另外目前在新一代通信系统的设计中，很多可用的频域资源的工作频点都比较高，导致网络覆盖的进一步降低。
发明内容
为克服相关技术中存在的问题，本公开实施例提供了一种通信方法及装置。

根据本公开实施例第二方面，提供一种通信方法，应用于网络设备，包括：
确定第一终端的协作终端；发送通知消息，所述通知消息用于通知确定的协作终端，所述协作终端为不同于所述第一终端的第二终端。
根据本公开实施例第三方面，提供一种通信装置，应用于第一终端，包括：
接收单元，被配置为获取网络设备发送的通知消息，所述通知消息用于通知确定的协作终端，所述协作终端为不同于所述第一终端的第二终端；处理单元，被配置为基于所述通知消息，确定用于协助所述第一终端传输数据的第二终端。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图 时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的通信方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相连接，并进行数据传输。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、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，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket  Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
为提高网络覆盖性能，相关技术中采用重复传输的方法。例如，图2所示的采用时域上重复传输的方法。比如在MTC和窄带物联网(Narrow Band Internet of Things，NB-IoT)中采用了重复传输以累积功率，进而达到覆盖增强的效果。简单来说，重复传输即在多个时间单位为传输相同的传输内容。这个时间单位可以是一个子帧，也可以是多个子帧。再例如，还可以通过图3所示的方式，在频域上跳频来获得频域上的分集增益，提高上行覆盖的性能。比如在长期演进(Long Term Evolution，LTE)的上行物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源映射方法中，通过把PUCCH映射在工作载波的频域两侧来提高PUCCH的接收性能，提高覆盖的性能。
但是时域上重复传输的方法会导致频谱资源的利用率会比较低，另外也会带来额外的时延。另外目前在新一代通信系统的设计中，很多可用的频域资源的工作频点都比较高，导致网络覆盖的进一步降低。
通过终端间的协调来提高覆盖是一个可行的技术方案，即，针对覆盖受限的终端，通过协作终端协助覆盖受限的终端进行信息传输。其中，协作终端为不同于覆盖受限的终端的其它终端。然而，如何识别协作终端需要明确。
本公开实施例中为描述方便，将覆盖受限的终端称为第一终端，将协助第一终端进行信息传输的终端称为第二终端，也有时称为协作终端。

其中，本公开实施例中网络设备向第一设备发送的配置信息中还可以包括指示第一终端需要检测的目标信号的信号特征。其中，目标信号的信号特征可以是信号的序列信息。第一终端在网络设备指示的位置上，依据信号特征监听到目标信号，并监听目标终端的目 标信号强度信息，并将测量结果上报给网络设备。网络设备根据测量结果确定第一终端的协作终端。
网络设备确定了第一终端的协作终端后，可以将协作终端的确定结果以通知消息的形式发送给第一终端和第二终端。
