Description

一种通信方法及相关设备 技术领域
本发明涉及通信技术领域，尤其涉及一种通信方法及相关设备。
背景技术
蜂窝通信系统在设计之初主要针对地面终端，如果蜂窝通信系统能够支持无人机将帮助无人机进行远距离飞行，这样无人机就可以充分地发挥图片采集、视频拍摄、运输等功能，从而给人们的生活带来更大便利。当无人机飞行高度超过基站后就会与跟多设备(包括基站和地面终端)之间无遮挡物遮挡，因此很多设备发送的信号容易被该无人机接收到，该无人机发送的信号也容易被很多设备接收到。如图1所示，当处于高空中的无人机与提供服务的基站0通信时，由于该无人机与基站1、基站2、地面终端1和地面终端2之间没有遮挡物遮挡，因此该无人机发送的的信号可能被基站1、基站2、地面终端1和地面终端2接收到，基站1、基站2、地面终端1和地面终端2发送的信号也可能被该无人机接收到。
蜂窝通信系统中如何为无人机配置通信资源，以减少无人机与通信系统中的设备之间的通信干扰是本领域的技术人员正在研究的技术问题。

具体实施方式
下面将结合本发明实施例中的附图对本发明实施例中的技术方案进行描述。
请参见图2，图2是本申请实施例提供的一种通信系统的结构示意图，该通信系统至少包括终端设备201和网络设备202和其他网络设备203。可选的，该通信系统20中的设备可以采用无线通信技术进行通信，例如，该无线通信技术可以为第二代移动通信技术(The2nd-Generation，2G)、第三代移动通信技术(The 3rd-Generation，3G)、长期演进(long term evolution，LTE)、第四代移动通信技术(the 4th Generation mobile communication，4G)、第五代移动通信技术(the 5th-Generation，5G)、或者无线保真(WIreless-Fidelity，WI-FI)技术、或者蓝牙技术、或者zigbee技术，或者其他现有的通信技术、或后续研究出的通信技术，等等。其中，终端设备201可以为具有无线通信功能的手持设备(例如，手机、平板电脑、掌上电脑等)、车载设备(例如，汽车、自行车、电动车、飞机、船舶、火车、高铁等)、可穿戴设备(例如智能手表、智能手环、计步器等)、智能家居设备(例如，冰箱、电视、空调、电表等)、飞行设备(例如，无人机、飞机)、智能机器人、车间设备、能够连接到无线调制解调器的其它处理设备，以及各种形式的用户设备、移动台(mobile station， MS)、终端设备(terminal)、终端设备(terminal equipment)，等等。网络设备202和其他网络设备203(数量可以为一个也可为多个)可以为网络侧的设备，例如，5G中的基站、4G中的基站，或其他任何可以实现无线网络接入功能的设备，等等。
请参见图3、图3是本发明实施例提供的一种通信方法的流程示意图，该方法可以基于图2所示的通信系统来实现，该方法包括但不限于如下步骤。
步骤S301：终端设备向网络设备发送报告消息。
具体地，终端设备与网络设备进行信令交互从而进入无线资源控制(radio resource Control，RRC)的连接态(connected mode)，该终端设备进入连接态后就可以向该网络设备发送报告消息，该报告消息用于报告该终端设备当前的状态。可选的，该报告消息用于报告该终端设备当前的高度，该高度可以为相对于地面的高度，也可以为海拔高度，还可以为其他形式的高度；可选的，该报告消息用于报告该终端设备当前所处的位置(如，经纬度)；可选的，该报告消息用于报告该终端设备当前移动的速度；可选的，该报告消息用于报告该终端设备属于哪种类型的设备，例如，用于报告该终端设备属于空中飞行的设备(如无人机)，该类型的划分有很多可能的情况，此处不做限定。可选的，该报告消息为用于表征该终端设备周围的各个小区的信号强度的测量报告。该报告消息包含的内容还存在其他情况，此处不一一举例。可选的，该网络设备会先向该终端设备发送配置信息来指示该终端设备发送该报告消息；可选的，该终端设备被预先配置了触发发送该报告消息的条件，该终端设备判断出该条件满足时则自动发送该报告消息。
步骤S302：该网络设备接收该终端设备发送的报告消息。
具体地，该网络设备需要确定该终端设备是否为满足预设条件的设备，满足该预设条件的设备可以包括处于预设的飞行状态的设备、高速移动的设备，及其他类似场景的设备。
可选的，该网络设备可以根据该报告消息中包含的信息来确定该终端设备是否为满足该预设条件的设备，例如根据该报告消息中包含的该终端设备当前高度、设备类型、测量的各个小区的信号等信息来确定该终端设备是否为满足该预设条件的设备。
可选的，该网络设备还可以将该报告消息发送给其他网元，由其他网元根据该报告消息来确定该终端设备是否为满足该预设条件的设备并将确定的结果通知给该网络设备，以使该网络设备获知该终端设备是否为满足该预设条件的设备。
可选的，该网络设备还可以通过其他网元获得该终端设备的授权或者认证信息来确定该终端设备是否为该满足预设条件的设备，该其他网元可以是核心网或者其他第三方节点。
步骤S303：该网络设备确定第一资源集合。
该第一资源集合用于该网络设备与满足该预设条件的设备通信，所述第一资源集合中的资源由一个小区中的部分资源组成或者由多个小区中的资源组成，后续可以称该至少一个小区中的每一个小区为一个第一小区。
可选的，当该第一资源集合中的资源由多个第一小区中的资源组成时，该多个第一小区中的一个或多个小区可以提供全部资源来组成该第一资源集合，也可以提供部分资源来组成该第一资源集合。该第一资源集合中的资源可以只包含上行传输资源，也可以只包含下行传输资源，还可以包含上行传输资源和下行传输资源。
进一步可选的，该第一资源集合中的资源为周期性的资源，或者，该第一资源集合中 的资源为静态配置或者半静态配置的资源，使用该第一资源集合中的资源进行通信能够减少信令交互，从而减少时延和节省通信资源。
进一步地，在同一传输时刻，所述第一资源集合仅服务于一个终端设备或者一个终端设备组，所述终端设备组由多个终端设备组成，在不同的传输时刻，所述第一资源集合中用于同向传输的资源在同一个载波上占用相同的频域位置。
其中，所述第一资源集合可以包含多个上行载波和/或下行载波。所述第一资源集合中的上行载波数、下行载波数、各个载波的带宽、各个载波在该第一资源集合中的位置可以通过资源配置信息通知给要所述第一资源集合所服务的终端设备或者终端设备组。在本发明实施例中，该终端设备组中的多个终端设备均属于满足上述预设条件的设备，例如，该终端设备组中的多个终端设备的高度均满足预设条件或者所述多个终端设备均处于预设的飞行状态。
该第一资源集合中的频域资源可以为系统带宽中的部分资源，例如，一段资源块(resource block，RB)范围、一段资源粒子(resource element，RE)范围，等等。该第一资源集合除了包含频域资源外，还可能包括时域、码域和波束域中至少一个维度的资源，当然也可能包含其他维度的资源。当该第一资源集合包含时域资源时，该时域资源的单位可以为现有的的帧、子帧、符号、时隙(slot)、微小时隙(mini slot)，即基本传输单元、符号组等，也可以为后续提出的其他形式的调度时间单位，后续可以以该时域的单位为子帧为例进行描述。该至少一个第一小区为多个第一小区时,该多个第一小区为该第一资源集合提供相同的时频资源。在同一传输时刻，该第一资源集合提供的资源仅被配置给所述第一资源集合所服务的终端设备或终端设备组，一定程度上降低了终端设备在下行和上行方向上的干扰；并且在所述第一资源集合是由多个第一小区提供的资源构成时，多个小区的覆盖范围增加，也降低了所述终端设备的切换频率。
可选的，当该第一资源集合中的资源仅用于供该终端设备组使用时，且该终端设备组包括该终端设备和其他终端设备，所述第一资源集合中的资源可以分配给所述终端设备组中的多个终端设备调度使用，为了便于区分可以称调度给该终端设备的资源为第一资源，以及调度给其他终端设备的资源为第二资源，所述第一资源和第二资源不重合，这里的不重合是指所述第一资源和第二资源的时域、频域、码域、波束域中的至少一个不相同。
在本发明实施例中，该第一资源集合可以是该网络设备与其他网络设备协商确定的，或者，该至少一个第一小区中各个第一小区提供的资源也可以由该网络设备通过操作维护(OAM)配置，又或者该第一资源集合也可以是定义在协议中的，例如，在协议中定义已知的第一小区1、第一小区2、第一小区3、第一小区4、第一小区5、第一小区6、第一小区7和第一小区8各分配部分资源用来构成该第一资源集合，这些第一小区中每个第一小区各分出什么资源出来可以根据需要来确定。
进一步，一种可选的方案中，该第一资源集合可以构成一个第二小区(也可称作“虚拟小区”)，该第二小区也有自身的小区标识，由于该第一资源集合由一个第一小区的部分资源或者多个第一小区的资源构成，因此该第二小区的信号覆盖范围为该至少一个第一小区的信号覆盖范围取并集，这样一来，当该终端设备在该第二小区范围内移动时，无需进行小区切换。另外，蜂窝网络中可以存在多个类似配置的、各自由相应的资源集合构成第 二小区(图4示意了2个第二小区)，这多个第二小区可以构成一个单频网，该多个第二小区中的各个第二小区提供的频域资源相同。
第二种可选的方案中，该第一资源集合未构成新的第二小区，所述第一资源集合所服务的该终端设备在移动时可能会在该多个第一小区之间切换。可选的，构成同一个第二小区的各个第一小区的载波相同，若两个第一小区分别用于构成不同的第二小区则这两个第一小区的载波不相同。
进一步的，该终端设备在蜂窝网络中通信时存在一条S1链路，具体是存在于核心网与控制单元(control unit，CU)(可以为该网络设备)之间的S1链路。下行数据的传输流程为：CU收到核心网发送的数据后将数据分发给至少一个数据单元(data unit，DU)(每个DU可以为上述至少一个第一小区中的一个第一小区的网络设备)，然后该至少一个DU中每个DU将收到的数据发送给该终端设备。上行数据的传输流程为：该终端设备将数据发送给该至少一个DU，该至少一个DU将接收到的数据发送给该CU，该CU接收到该至少一个DU发送的数据后将接收到的数据发送给该核心网。具体的协议栈设置如图5所示，CU和DU的协议栈从媒体访问控制(media access control，MAC)层分开，MAC层在CU的部分可以称为High MAC(功能包括MAC层MAC控制元素(MAC control element，MAC CE)生成和接收，复用和解复用，调度功能)，MAC层在DU的部分可以称为Low MAC(功能包括上行混合自动重传请求(hybrid automatic repeat request，HARQ)和下行bundling捆绑发送)。该至少一个DU需要在相同时间使用相同的频域资源发送相同的数据给该终端设备，例如，该至少一个DU需要在SFN2，子帧3的RB10-15同时发送资源块TB1给该终端设备。为实现这一功能，首先TB1由High MAC生成，再传输给low MAC由low MAC进行发送。在传给low MAC TB1数据包的同时还需要指示具体的发送时刻，以便该至少一个DU的low MAC都在该发送时刻发送该TB1。指示该发送时刻的信息可以是具体的帧号和子帧号，也可以是一个表示时刻的索引值(例如，以10秒钟为一个周期，共10000毫秒(ms)，可以设置0到9999的索引值来依次标记第1ms到第10000ms)。
可选的，上述至少一个第一小区中每个第一小区属于一个网络设备，假设这至少一个第一小区所属的网络设备为多个，这多个网络设备中包括一个锚点网络设备和至少一个节点网络设备，该多个网络设备可以构成图5所示的CU-DU分离架构，该锚点网络设备为中心单元CU，该至少一个节点网络设备均为数据单元DU。
对于下行传输，各个DU会在相同的时频资源采用相同的调制编码方式向终端设备发送相同的数据，下行不采用HARQ而采用捆绑(bundling)发送的方式来提高可靠性。
对于上行传输，终端可以在第一资源集合的资源上发送数据，此数据会被多个DU接收，每个DU会对数据进行CRC校验。如果CRC校验结果正确就向终端反馈ACK，如果不正确就不向终端设备反馈任何数据。此时，对于一次上行数据传输，终端设备如果能够检测到DU反馈的ACK，则确认数据发送成功；如果没有接收到ACK(例如在指定时频资源上收到ACK，或在一段时间内始终没有收到ACK)，则确认数据发送失败。在确认数据发送失败的情况下，终端设备会发起上行数据重传。重传的方式有以下两种：
方式1：HARQ重传方式。即每次重传采用不同的冗余版本，此时终端设备需要向DU指示HARQ进程号和相应的冗余版本索引信息。由于HARQ进程号和相应的冗余版本索引 信息涉及到数据包的解调，所以不能放置在传输块中，需要通过物理层的方式进行指示。一种方式为，在专用的RE或RB资源上区分不同的位置指示相应的HARQ进程号和相应的冗余版本索引信息，例如将每个子帧中第一个符号的6个RB用于指示HARQ进程号和相应的冗余版本索引；另一种方式为，通过上行解调参考信号(Demodulation Reference Signal，DMRS)来指示，示例的，DMRS具有不同的循环移位值，还可以具有不同正交掩码(orthogonal cover code，OCC)，DMRS的循环移位值可以对应HARQ进程号，OCC码索引可以对应冗余版本索引。循环移位取值范围是0-11，HARQ进程号范围是0-7，能够完全对应。OCC码索引范围为0-1，冗余版本索引范围是0-3，不能完全对应，可以扩大OCC码索引(例如扩展为0-3)或者减少可用的冗余版本(例如只用1和2)。
方式2：非HARQ重传方式。即每次重传的冗余版本都是0，也就是相当于重新进行一次新传。此时只需要发送数据，而不需要指示HARQ进程号和冗余版本索引。
可选的，该资源指示信息还可以指示具体的调度信息，包括但不限于频域位置信息(例如指示在资源块RB10到资源块15发送TB1)，调制与编码策略(modulation and coding Scheme，MCS)信息，跳频指示信息，信道质量指示(channel quality indicator，CQI)上报指示信息等。
步骤S304：该网络设备向该终端设备发送资源配置信息。
当存在上述第二小区时，该终端设备驻留的小区为该第二小区，当不存在该第二小区时，该终端设备驻留的小区为该至少一个第一小区中的一个第一小区。该网络设备可以通过高层信令来承载该资源配置信息，该高层信令可以为在RRC、MAC、无线链路层控制协议(radio link control，RLC)和分组数据汇聚协议(packet data convergence protocol，PDCP)中至少一项上进行发送。当存在上述第二小区时，该资源配置信息包括该终端设备驻留的第二小区标识，第二小区标识可以以虚拟小区标识或者物理小区标识的格式定义；
进一步可选的，该资源配置信息进一步包括为所述第二小区提供资源的所述至少一个第一小区的标识；
当不存在该第二小区时，该资源配置信息包括该终端设备驻留的第一小区标识或者/和共同组成该第一资源集合的第一小区的列表。该资源配置信息可以包括该终端当前驻留/服务的小区的物理层配置，除此之外还可能包括该终端当前驻留/服务的小区的小区标识，该终端在驻留/服务的小区的接入信息，该终端在驻留/服务的小区的高层配置，等等。以下分别对资源配置信息包括的和可能包括的信息进行介绍。
物理层配置：该物理层配置中包含用于指示上述第一资源集合的信息。其中，对于该第一资源集合中的频域的的指示存在多种可能的方式，可选的，可以通过指示频域的起始位置、带宽和结束位置中至少两项来指示该第一资源集合中的资源的频域，也可能系统带宽中的各个频段预先有了编号，这样一来就可以通过指示一个频域序号来实现对该频域序号对应的频段进行指示，其余指示方式此处不再一一举例。
当该第一资源集合包含时域资源时，该时域的的指示方式包括但不限于如下几种：
方式一：该资源配置信息通过指示时域的起始位置、长度、周期、偏移量和结束位置中至少两项来指示该第一资源集合包含的时域位置，例如，以子帧为单位并按照指示周期和偏移量的方式来指示该第一资源集合中的时域，假设周期为T，偏移值为offset，一个帧 内的子帧总数为M，则该第一资源集合包含的子帧号x可以按照以下公式计算x＝(T*N+offset)mod(M)，其中N为第一资源集合中资源周期的序号，N从0开始算；或者则该第一资源集合包含的子帧号x可以按照以下公式计算x＝(T*(N-1)+offset)mod(M)，其中N为第一资源集合中资源周期的序号，N从1开始算；好比5ms一个周期，每5ms的周期里的第二个子帧(如，第二个子帧为号为#1，第一个子帧号为#0)，有效的资源时长是1ms，即一个子帧，那么，第3个周期的子帧号x＝(5*(3-1)+1)mod 10。
方式二：通过帧号和子帧号联合计算，例如(10*SFN+subframe)＝[(10*SFNstart time+subframestart time)+N*周期值]modulo 10240，其中SFN为帧号，subframe为子帧号，SFNstart time和subframestart time为半静态调度起始的帧号和子帧号。相比于方式一，公式中引入了帧号，所以需要该网络设备与该其他网络设备之间的帧号相同，同时这种方式也可以使用超过一个帧长度的周期。
方式三：该资源配置信息通过传输时间单位图样来指示该第一资源集合包含的时域位置，直接指示固定的子帧(属于一种调度时间单位)图样，即直接规定具体的用于第一资源集合的帧号和子帧号，例如规定单数帧中的子帧1和子帧2为该第一资源集合的子帧。也可以只规定子帧号，即每一帧中相应的子帧都属于该第一资源集合。
另外，当该第一资源集合中包含上行的资源和下行的资源时，指示下行的资源用到的参数与指示上行的资源用到的参数可能相同也可能不相同。例如，假设该第一资源集合包括多个载波，如图6A所示，上行资源包含N个载波(N为正整数)，上行资源的时间位置以符号组为单位。载波1中每个资源时域上占用1个符号，每个符号间隔为6个符号，频域上占用4个资源块RB；载波2中每个资源时域上占用2个符号，每个符号组间隔为5个符号，频域上占用3个RB；载波N每个资源包含3个时域符号，每个符号组间隔4个符号，频域上占用4个RB。而下行资源包含M个载波(M为正整数)，时域以单个子帧长度为单位。载波1周期为2个子帧，偏移值为1，频域占用2个RB；载波2周期为4个子帧，偏移值为1，频域占用3个RB；载波M周期为2个子帧，偏移值为1，频域占用3个RB，所以每两个子帧出现一个虚拟通信区子帧。再如，假设该第一资源集合包括一个载波，如图6B所示，上行资源的时间位置以符号组为单位，每个资源包含3个时域符号，每个符号组间隔4个符号。而下行资源以单个子帧长度为单位，周期为2个子帧，偏移值为1，所以每两个子帧出现一个虚拟通信区子帧。可选的，第一资源集合中下行资源并不占据子帧内全部符号，只是占用部分符号，如占用子帧内的后11个符号，前3个符号仍用于物理下行控制信道(physical downlink control channel，PDCCH)(以子帧内包含14个符号为例)。
可选的，该第一资源集合中还可以存在多种信道，例如，当该第一资源集合构成一个第二小区时，该第一资源集合内需要划分出较多的信道来支持该第二小区的正常运行。该网络设备可以通过上述物理配置来指示该第一资源集合中的信道的划分方案，当然也可能该第一资源集合内的信道的划分方式可以在协议中规定好，这样该网络设备就不需要通过上述物理配置来指示该第一资源集合中的信道的划分方案了。为了便于理解，以下例举几种可能的信道划分方案：
方案一：该第一资源集合包括用于下行传输的时频资源和用于上行传输的时频资源，且用于下行传输的时频资源和用于上行传输的时频资源均可以用于数据信道的传输。
方案二：该第一资源集合包括用于下行传输的时频资源和用于上行传输的时频资源，且用于下行传输的时频资源和用于上行传输的时频资源均可以用于数据信道的传输。并且该下行传输包括同步信号、用于测量或解调的参考信号和控制信道中至少一项的传输，该上行传输包括参考信号、随机接入信道和控制信道中至少一项的传输。
可选的，该第一资源集合内包含的信道的类型可以与长期演进(long term evolution，LTE)中信道划分方式类似，相对与LTE而言是压缩的版本(因为LTE中可用的时频资源的资源范围远大于该第一资源集合的资源范围)。如图7所示，假设该第一资源集合中用于下行传输的时频资源的时域包括一个子帧中的后11个符号(这11个符号的索引范围从3到13)且频域包括6个RB，那么可以使控制信道和同步信道分别占用一个单独的符号，数据信道占用其他的符号，并且在数据信道中分布着用于进行信道估计的解调参考信号。控制信道中可以携带对终端设备的调度指示信息。如图8所示，假设该第一资源集合中用于上行传输的时频资源的时域包括一个子帧且频域上占用5个RB，那么可以使控制信道占用一个RB，可选的，还可以采用跳频设计，即在两个时隙上占用的频域位置不同；解调参考信号占用两个符号，分别为符号3和符号10；其余位置为数据信道占用，终端设备也可以在数据信道中反馈下行数据的确认反馈(ACK)/否定反馈(NACK)。
上述物理层配置还可以指示其他信息，例如，该终端驻留的小区的至少一个参考信号或序列，其中，该至少一个参考信号或序列能够用于小区同步、信道解调、信道评估、无线资源管理(radio resource management，RRM)测量中的至少一种，至少一个物理信道、天线信息、扰码序列索引(scrambling sequence index，SCID)、扰码序列索引、预编码信息、信道矩阵信息、码本信息、层信息、天线端口数、天线端口号、波束优化能力信息、有效时间、有效时长、控制信道、循环前缀(cyclic prefix，CP)长度和功率控制信息。当该第一资源集合中包含控制信道时，可以通过该物理层配置指示该控制信道采用增强的控制信道，采用增强的控制信道能够实现波束成型功能，并承载该终端驻留的小区的公共的和/或专用的控制信息。例如，可以指示与波束特性相关的配置，具体可以包括以下至少一个属性，参考信号(如，解调参考信号(demodulation reference signals，DM-RS))、SCID扰码序列索引number(0or 1)、预编码(precoding)，码本信息，端口数，端口号，有效时间，有效时长；另外，小区的控制信道可以采用ePDCCH或者其他增强的控制信道，这种类型的控制信道可以像物理下行共享信道(physical downlink shared channel，PDSCH)一样实现波束成型功能，公共的和/或专用的控制信息可以承载在这种类型的控制信道上传输。
该终端驻留/服务的小区的小区标识：当上述第一资源集合构成了一个第二小区时，该终端驻留/服务的小区为该第二小区，该第二小区的小区标识(该第二小区也可能被称为虚拟小区，该虚拟小区的小区标识可能为VCID)可以为波束标识，探测参考符号(sounding reference signal，SRS)的标识、用于识别该终端的信息(例如，标识、标识码、序列等)等。在本发明实施例中，由于该终端使用的资源来自该至少一个第一小区提供的资源所组成的第一资源集合，因此，该资源配置信息还可能包括该第一资源集合的标识或者该第一资源集合中的该资源所属的至少一个第一小区(也可以称为物理小区)的小区标识的列表，其中，该第一资源集合的标识包括第二小区的小区标识，波束标识，该终端的标识信息，以及探测参考符号SRS的标识中至少一项。
该终端驻留/服务的小区的接入信息：如，该终端驻留/服务的小区的能力信息、能够提供的业务信息、公共陆地移动网络(public Land mobile network，PLMN)标识、跟踪区(tracking area，TA)码，载波/频率信息、工作模式信息、逻辑信道配置信息、物理信道、信令配置信息、定时器信息，等等。
该终端驻留/服务的小区的高层配置：该终端的信令或数据承载对应的PDCP层、RLC层和/或MAC层的配置，这有利于网络设备准确调整波束特性的测量信息。也可能有测量配置。该测量信息可以进一步包括控制该终端设备从共同组成该第一资源集合的第一小区中选择共同为该终端设备通信的至少一个第一小区的协作集的测量控制和测量上报控制的信息。其中，测量控制信息包括以下至少一种信息：测量对象，如进行测量的频段和/或小区的信息；测量的目的，进行从共同组成该第一资源集合的第一小区中选择共同为该终端设备通信的至少一个第一小区的协作集；测量的参考信号的信息，同步信号(synchronization signal，SS)，小区专有导频(cell-specific reference signals，CRS)，信道状态信息测量导频(channel state information RS，CSI-RS)和/或DM-RS；测量的周期；其中，测量上报控制信息包括以下至少一种信息：该终端设备从共同组成该第一资源集合的第一小区中选择共同为该终端设备通信的至少一个第一小区的协作集的事件定义；上报的小区个数限制；测量结果类型；测量报告触发的迟滞时间等。
步骤S305：该终端设备接收该网络设备发送的资源配置信息。
具体地，该终端设备会解析出该资源配置信息中的物理层配置，当该资源配置信息还包含其他信息时该终端设备还会解析出该资源配置信息中的其他信息，例如，接入信息、高层配置，等等。该终端设备可以根据该物理层配置确定该第一资源集合、该第一资源集合中的信道划分方案、上述第一资源，等等。该终端设备后续还可以根据该物理层配置成功地从驻留的小区解调出数据和/或控制信息。比如，终端设备从控制信息(如下行控制信息(downlink control information，DCI)中SCID)中获得天线端口信息、层(layer)信息和扰码标识，从而得到参考信号在该驻留的小区的具体资源位置，然后终端设备通过测量参考信号，得到H*W(信道矩阵*码本(或称为加权向量))，或者得到H(信道矩阵)，然后，终端设备就可以根据HW或者H成功的从该驻留的小区解出数据和/或控制信息。当终端设备接收到网络设备发送的控制信息后，通过对控制信息进行解析，获取到控制信息所指示的子载波信息、信道信息、时频信息等。由天线形成的至少一个波束提供通信区的公共控制信道、专用控制信道、业务信道等多个物理信道，该波束还可以用于该终端设备和该网络设备之间的数据传输。
可选的，当该终端设备从该资源配置信息中解析出该第一终端所在驻留的小区的小区标识、接入信息、高层配置等信息时，该终端设备对这些信息的使用与现有技术中使用这些信息的方式类似，具体原理此处不再赘述。
步骤S306：该终端设备使用该第一资源集合中的第一资源与该网络设备通信。
具体地，该终端设备与该网络设备通信时会用到驻留的小区的即物理小区标识(Physical Cell Identifier，PCI)、小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)，在通信过程中该终端设备会对驻留的小区的SS进行同步和测量，以及对驻留的小区的CRS格式进行测量，根据定义的周期和事件触发对共同组成该第一资源 集合的第一小区中，选择共同为该终端设备通信的至少一个第一小区的协作集等。那么当存在上述第二小区时，该终端设备与该网络设备通信时会用到该第二小区的标识(可能称为VCID，相当于上述PCI)、C-RNTI，在通信过程中该终端设备会对该第二小区的SS进行同步和测量，以及对该第二小区的CRS格式进行测量。
可选的，当所述第一资源集合仅服务于一个终端设备组，且该终端设备为该终端设备组中的一个设备(可以称为第一终端设备)，那么，该网络设备在向该终端设备发送了上述资源配置信息之后，还向该第一终端设备发送调度信息，所述调度信息用于指示所述第一资源集合中的第一资源，因此，该第一终端设备可以先根据该资源配置信息确定该第一资源集合，进一步根据该调度信息确定该第一资源集合中的第一资源，然后使用该第一资源与该网络设备通信。
可选的，当所述第一资源集合仅服务于一个终端设备时，该终端设备根据该资源配置信息确定了第一资源集合之后，使用该第一资源集合中的全部资源来与该网络设备通信，或者根据预先定义的规则从该第一资源集合中选择部分资源来与该网络设备通信。
在图3所示的方法中，该网络设备确定第一资源集合并将该第一资源集合配置给终端设备使用，由于在同一传输时刻，该第一资源集合中的资源仅用于所述终端设备或所述终端设备组使用，因此该被配置了该第一资源集合的终端设备使用该第一资源集合中的资源通信时降低下行和上行干扰，同时会降低切换频率。
