Description

无线通信的方法和设备
本申请要求于2016年9月30日提交中国专利局、申请号为201610877877.8、申请名称为“无线通信的方法和设备”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
本申请实施例涉及通信领域，并且更具体地涉及一种无线通信的方法、网络设备和终端设备。
背景技术
目前，根据国际电信联盟(International Telecommunication Union，ITU)对未来通信系统的要求，未来通信系统中的空口需要支持各种业务，例如：增强移动带宽(Enhanced Mobile Broadband，eMBB)业务，极高可靠性低时延通信(Ultra-reliable Low Latency Communication，URLLC)业务，海量机器类型通信(Massive machine-type communication，Massive MTC)业务等等。
上述不同的业务对通信系统的要求不一样，有的业务对时延要求比较高，有的业务对时延要求比较低。现有技术中，长期演进系统(Long Term Evolution，LTE)中网络设备可以向终端设备发送下行控制信道，以调度终端设备在下行控制信道所指示的时频资源上接收其当前业务的下行消息。
为了满足时延要求比较高的业务的传输要求，可以考虑以下方案，即，网络设备在调度了当前业务时延要求比较低的终端设备接收消息后，网络设备将基于下行控制信道分配给业务时延要求比较低的终端设备的时频资源分配给业务时延要求比较高的终端设备。
但是，该方案下，业务时延要求比较低的终端设备仍然在该被重分配的时频资源上进行接收数据(例如，对在该被重分配的时频资源上数据解调或解码)，从而造成性能损失。
发明内容
本申请实施例提供一种无线通信的方法、网络设备和终端设备，能够减小由于资源重分配造成的终端设备的接收性能损失。
第一方面，提供了一种无线通信的方法，包括：网络设备发送物理下行控制信道(Physical Downlink Control Channel，PDCCH)，所述PDCCH用于指示网络设备调度的时频资源；网络设备对所述时频资源中的至少一个时频资源进行重分配；网络设备发送至少一个后资源指示信息，所述至少一个后资源指示信息用于指示所述时频资源中被重分配的时频资源。
网络设备可以向在当前调度周期内被调度的各终端设备发送物理下行控制信道PDCCH，PDCCH中可以携带分配给在当前调度周期内被调度的各终端设备的时频资源。 网络设备通过向当前调度周期内被调度的部分或全部终端设备发送至少一个后资源指示信息，可以指示PDCCH调度的时频资源中被重分配的时频资源。进而，终端设备可以根据PDCCH和所述至少一个后资源指示信息，确定网络设备在当前调度周期内分配给该终端设备的时频资源中是否有被重分配的时频资源，以及在当前调度周期内分配给该终端设备的时频资源中被重分配的时频资源。从而，终端设备可以只接收(例如，解码或解调)承载于分配给该终端设备的时频资源中没有被重分配的时频资源上的数据，不接收(例如，不解码或不解调)承载于分配给该终端设备的时频资源中被重分配的时频资源上的数据，实现下行数据的正确接收。因此，本申请实施例的无线通信的方法，能够减小由于资源重分配造成的终端设备的接收性能损失。
在一种可能的实现方式中，所述时频资源在时域上对应至少一个时域调度单位，每个时域调度单位包括至少一个迷你时隙，或每个时域调度单位包括至少一个符号。
所述时域调度单位可以是标准规定的。所述调度时域单位也可以是网络设备通过系统消息、广播消息、或者高层信令配置。
可选地，所述符号可以是正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号也可以是单载波频分多址(Single-carrier Frequency-Division Multiple Access，SCFDMA)符号。
在一种可能的实现方式中，所述至少一个后资源指示信息包括至少一个公共后资源指示信息，所述至少一个时域调度单位与所述至少一个公共后资源指示信息一一对应，所述至少一个公共后资源指示信息中的第I个公共后资源指示信息被在所述第I个公共后资源指示信息对应的时域调度单位中被调度的部分或全部终端设备接收，每个公共后资源指示信息用于指示所对应的时域调度单位中被重分配的时频资源，I∈[1，X]，X为所述公共后资源指示信息的数量。
所述部分终端设备可以是所使用的时频资源可能被重分配的终端设备。
本申请实施例中，当前调度周期内被调度的所有终端设备均可以接收所述至少一个后资源指示信息。或者，在当前调度周期内被调度的所有终端设备中只有时频资源可能被重分配的终端设备才接收所述至少一个后资源指示信息。
本申请实施例的无线通信的方法，终端设备通过检测分配给该终端设备的时频资源所属的时域调度单位对应的公共资源指示信息，可以确定分配给该终端设备的时频资源中是否有被重分配的时频资源，以及分配给该终端设备的时频资源中被重分配的时频资源。从而，终端设备可以只接收(例如，解码或解调)承载于分配给该终端设备的时频资源中没有被重分配的时频资源上的数据，不接收(例如，不解码或不解调)承载于分配给该终端设备的时频资源中被重分配的时频资源上的数据，实现下行数据的正确接收。因此，本申请实施例的无线通信的方法，能够减小由于资源重分配造成的终端设备的接收性能损失。

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。
本申请实施例涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，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其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。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。无线终端也可以称为系统、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)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
本申请实施例所涉及的网络设备，可以是基站，或者接入点，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线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网际协议(Internet Protocol，IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(evolutional Node，BeNB或e-NodeB)，5G网络中的网络设备，本申请并不限定。
本申请实施例提供的无线通信的方法，适用于任一无线通信系统下对发送消息或接收消息时延要求比较低的终端设备，以及调度该终端设备发送消息或接收消息的网络设备。这里所说的无线通信系统例如可以为LTE通信系统、4G通信系统、5G通信系统等等。
以LTE通信系统为例，现有技术中，如图1所示，网络设备101在通过下行控制信道调度了当前业务时延要求比较低的终端设备102接收网络设备101发送的下行数据之后，若网络设备101需要再调度传输时延要求较高的终端设备103接收网络设备101发送的下行数据时，网络设备101可以在分配给终端设备102的时频资源发送下行数据。但网络设备101在分配给终端设备102的时频资源发送终端设备103的下行数据时，会造成终端设备102的性能损失。
本申请实施例提供的无线通信的方法，旨在解决现有技术由于资源重分配造成的时延要求比较低的终端设备的性能损失的问题。下面以具体地实施例对本申请的技术方案进行详细说明。下面所涉及的具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
首先，介绍本申请实施例中所涉及的相关概念。
普通终端：终端设备的业务为对传输时延要求低于紧急终端的业务。
紧急终端：终端设备的业务为对传输时延敏感的业务。
图2示出了本申请实施例的无线通信的方法200的示意性交互图。如图2所示，该方法200包括：
S210，网络设备可以向在当前调度周期内被调度的各终端设备发送物理下行控制信道 PDCCH。以下，为了便于理解和区分，将上述在当前调度周期内被调度的各终端设备记做：终端设备#1～终端设备#N，其中，该终端设备#1～终端设备#N中包括普通终端，其中，N≥1。
其中，该PDCCH中可以携带有分配给终端设备#1～终端设备#N中的每个终端设备的时频资源，以下，为了便于理解和区分，分配给终端设备#1～终端设备#N中的每个终端设备的时频资源记做：时频资源#1～时频资源#N。其中，该时频资源#1～时频资源#N与终端设备#1～终端设备#N一一对应，例如，时频资源#1可以是PDCCH指示的分配给终端设备#1的时频资源，时频资源#2可以是PDCCH指示的分配给终端设备#2的时频资源，依此类推，时频资源#N可以是PDCCH指示的分配给终端设备#N的时频资源，这里，为了避免赘述，省略其详细说明。
S220，网络设备对时频资源#1～时频资源#N中的至少一个时频资源进行重分配。更具体地说，网络设备对时频资源#1～时频资源#N中分配给普通终端的一个或多个时频资源进行重分配，以下，为了便于理解和区分，将被重新分配的时频资源，记做：时频资源#M，其中，时频资源#M的数量可以是一个也可以是多个，本申请并未特别限定。
S230，网络设备发送用于指示该时频资源#M被重分配的指示信息(即，后资源指示信息的一例)。
作为示例而非限定，该后资源指示信息可以是被多个终端设备检测并接收的公共信息(即，情况1)，或者，该后资源指示信息可以是被一个终端设备检测并接收的专用信息(即，情况2)，下面，分别对以上两种情况下的具体流程进行详细说明。
情况1
可选地，该时频资源在时域上对应至少一个时域调度单位，每个时域调度单位包括至少一个迷你时隙，或每个时域调度单位包括至少一个符号。发明涉及的符号可以是OFDM符号也可以是SCFDMA符号。
具体地说，在本申请实施例中，PDCCH调度的时频资源在时域上可以对应至少一个时域调度单位。
其中，“PDCCH调度的时频资源在时域上可以对应至少一个时域调度单位”可以理解为：PDCCH调度的时频资源在时域上位于至少一个时域调度单位的范围内，即，PDCCH调度的时频资源是至少一个时域调度单位的一部分。
或者，其中，“PDCCH调度的时频资源在时域上可以对应至少一个时域调度单位”可以理解为：PDCCH调度的时频资源在时域上包括至少一个时域调度单位中的全部时域范围。
下面，首先对本申请实施例中的时域调度单位进行说明。
具体地说，本申请实施例涉及的时域调度单位可以是标准规定的。
例如，一个时域调度单位可以包括一个子帧(14个符号)。
再例如，一个时域调度单位可以包括一个时隙(7个符号)。
再例如，一个时域调度单位可以包括一个或多个迷你时隙(mini-slot)。
其中，迷你时隙可以是指所包括的符号数量小于7。
作为示例而非限定，在本申请实施例中，可以为每个迷你时隙分配索引，并且，每个迷你时隙包括的符号的数量与迷你时隙的索引对应。例如，一个时域调度单位包括6个迷 你时隙，该6个迷你时隙的索引可以依次为012345。
作为示例而非限定，例如，在一个时域调度单位中，索引为0的迷你时隙对应的符号的数量可以为3，索引为1的迷你时隙对应的符号的数量可以为2，索引为2的迷你时隙对应的符号的数量可以为2，索引为3的迷你时隙对应的符号的数量可以为3，索引为4的迷你时隙对应的符号的数量可以为2，索引为5的迷你时隙对应的符号的数量可以为2。即，在该时域调度单位中，各迷你时隙包括的符号的数量可以依次为322322。
再例如，在一个时域调度单位中，索引为0的迷你时隙对应的符号的数量可以为2，索引为1的迷你时隙对应的符号的数量可以为2，索引为2的迷你时隙对应的符号的数量可以为3，索引为3的迷你时隙对应的符号的数量可以为2，索引为4的迷你时隙对应的符号的数量可以为2，索引为5的迷你时隙对应的符号的数量可以为3。即，在该时域调度单位中，各迷你时隙对应的符号的数量可以依次为223223。
再例如，一个时域调度单位可以包括3个迷你时隙，各迷你时隙包括的符号的数量依次是322或223。
再例如，一个时域调度单位可以包括4个迷你时隙，各个迷你时隙包括的符号的数量依次是4343或3434。
再例如，一个时域调度单位包括2个迷你时隙，各迷你时隙包括的符号的数量依次是43或34。
另外，本申请实施例涉及的调度时域单位也可以是网络设备通过系统消息、广播消息、或者高层信令配置。网络设备配置的时域调度单位可以参照上文中关于标准规定的时域调度单位的描述，为了简洁，此处不再赘述。
下面，对上述时域调度单位结构下的后资源指示信息的发送方式进行详细说明。
可选地，该至少一个后资源指示信息包括至少一个公共后资源指示信息，该至少一个时域调度单位与该至少一个公共后资源指示信息一一对应，该至少一个公共后资源指示信息中的第I个公共后资源指示信息被在该第I个公共后资源指示信息对应的时域调度单位中被调度的部分或全部终端设备接收，每个公共后资源指示信息用于指示所对应的时域调度单位中被重分配的时频资源，I∈[1，X]，X为该公共后资源指示信息的数量。
不失一般性，设PDCCH调度的时频资源在时域上可以对应T个时域调度单位，T≥1。
则对于T个时域调度单位中的任意一个时域调度单位Tα，其中，α∈[1，T]，如果时域调度单位Tα对应的时间范围内存在被重分配的时频资源，即，时频资源#M中存在属于时域调度单位Tα的时频资源，则网络设备可以将在该时域调度单位Tα的时间范围内发送与时域调度单位Tα相对应的公共后资源指示信息Hα，其中，该公共后资源指示信息Hα可以指示时域调度单位Tα对应的时间范围内存在的被重分配的时频资源，或者说，该公共后资源指示信息Hα可以指示时频资源#M中属于时域调度单位Tα的时频资源。
需要说明的是，如果将在该时域调度单位Tα内的被调度的所有终端设备记做：终端设备Tα，则该终端设备Tα可以包括一个或多个第一类终端设备，以下，为了便于理解和区分，记做：终端设备Tα-1，其中，该终端设备Tα-1可以是所使用的时频资源可能被重分配的终端设备。
作为示例而非限定，在本申请实施例中，所有终端设备Tα可以均为上述第一类终端 设备，从而，该终端设备Tα中的全部设备可以均检测该公共后资源指示信息Hα。
或者，在本申请实施例中，该终端设备Tα还可以包括一个或多个第二类终端设备，以下，为了便于理解和区分，记做：终端设备Tα-2，其中，该终端设备Tα-2可以是所使用的时频资源不可能被重分配的终端设备。例如，PDCCH指示的分配的物理下行共享信道(Physical Download Share Channel，PDSCH)的结束符号距离PDCCH的结束符号仅有v个符号的终端设备。其中，v≥1。也就是说，PDSCH占用的时域资源较少并且靠近PDCCH的时，PDSCH的时频资源不会被重分配。再如，PDCCH指示的分配的频域资源的带宽小于一定数量的终端设备。例如，分配的带宽小于48个子载波或者36个子载波的终端设备的时频资源不会被重分配。从而，该终端设备Tα中的终端设备Tα-2可以不检测该公共后资源指示信息Hα。从而，该终端设备Tα-1能够根据所检测到的该公共后资源指示信息Hα判定PDCCH分配给该终端设备Tα-1的属于该时域调度单位Tα的时频资源是否被重分配。如果判定为是，则该终端设备Tα-1可以不接收(例如，不解码或不解调)承载于被重分配的时频资源上的数据。
如果判定为否，则该终端设备Tα-1可以接收(例如，解码或解调)承载于PDCCH分配给该终端设备Tα-1的属于该时域调度单位Tα的时频资源中所有时频资源上的数据。
下面，对承载公共后资源指示信息Hα的时频资源在该时域调度单位Tα中的时域位置进行说明。
例如，可选地，每个公共后资源指示信息在时域上承载于所对应的时域调度单位中的后M个符号，M≥1。
具体地说，作为示例而非限定，对承载公共后资源指示信息Hα的时频资源在该时域调度单位Tα中位于最末尾的M个符号。
应理解，以上列举的承载公共后资源指示信息Hα的时频资源在该时域调度单位Tα中的时域位置仅为示例性说明，本申请并未限定于此，承载公共后资源指示信息Hα的时频资源在该时域调度单位Tα中的位置可以是任意的，并且，该承载公共后资源指示信息Hα的时频资源(例如，符号)的数量也可以是任意确定的，并且，当承载公共后资源指示信息Hα的时频资源包括多个符号时，该多个符号可以是连续的也可以是不连续的，本申请并未特别限定。
可选地，承载公共后资源指示信息Hα的RE数目是固定的。
进一步地，公共后资源指示信息Hα可以承载于时域调度单位Tα的最后一个符号，并且可以均匀地分布在频域资源中的可以被重分配的频域资源内。公共后资源指示信息Hα的频域位置可以随被重分配的频域资源的带宽的大小的变化而发生变化。网络设备通过将被重分配的频域资源均匀地分布在可以被重分配的整个频带内，可以获得频率增益，增加公共后资源指示信息Hα的传输可靠性。
图3和图4示出了本申请实施例的一个进行资源重分配的时频资源的示意图。如图3和图4所示，终端设备#1的时频资源#1在时域上包括时域调度单位T1中第3个符号，终端设备#2的时频资源#2在时域上也包括时域调度单位T1中第3个符号。时域调度单位T1中第3个符号被重分配给第三紧急终端，公共后资源指示信息H1占用时域调度单位T1的最后一个符号，并且均匀地分布在整个系统频带内。
可选地，用于承载所述至少一个后资源指示信息的时频资源为系统规定的预留资源。
具体地说，在本申请实施例中，承载公共后资源指示信息Hα的时频资源在该时域调度单位Tα中的时域位置可以是系统规定的，并且，该承载公共后资源指示信息Hα的时频资源可以被禁止用于承载除该公共后资源指示信息Hα以外的信息。
另外，在本申请实施例中，该承载公共后资源指示信息Hα的时频资源可以是公共资源，即该承载公共后资源指示信息Hα的时频资源能够被多个终端设备(例如，上述终端设备Tα-1)检测到。
可选地，本申请实施例中，每个时域调度单位在频域上可以对应q个频段。每个公共后资源指示信息可以包括q个比特组，q个频段与q个比特组一一对应。每个比特组可以包括k-y个比特，对于频段Fj所对应的比特组Zj，比特组Zj中的k-y个比特与频段Fj所对应的k个迷你时隙或符号一一对应，比特组Zj中的比特的比特值用于指示与频段Fj所对应的时域调度单位上的后k-y个迷你时隙或符号是否被重分配，其中，k≥1，q≥1，y≥0，k＞y，j∈[1，k]，k为时域调度单位包括的迷你时隙或符号的数量。
具体地，q＝1且y＝1时，每个时域调度单位在频域上可以对应一个频段F1，该频段F1是整个可以被调度的频域资源。此时，每个公共后资源指示信息可以包括一个比特组Z1，比特组Z1包括的k个比特与k个迷你时隙或符号一一对应。k个比特的比特值可以用于指示分别占频段F1的k个迷你时隙或符号是否被重用。举例来说，在每个时域调度单位包括6个符号，即k＝6时，每个公共后资源指示信息可以包括6个比特。按照符号的索引大小，6个比特依次指示第1个至第6个符号是否被重分配。其中，被重分配的符号在频域上占满整个可以被调度的频域资源。比如公共后资源指示信息H1的6个比特为000101，表示时域调度单位T1的第4个和第6号符号被重的分配。或者，6个比特为111010时，表示第4个和第6号符号被重分配。
当q＞1且y＝1时，以q＝2为例进行说明。每个时域调度单位在频域上对应2个频带，也就是说，整个可以被调度的频域资源可以分为2个频段，即频带F1和频带F2。频带F1和频带F2的带宽可以相等，也可以不等，本申请实施例对此不做限定。此时，每个公共后资源指示信息可以包括2个比特组，比特组Z1对应频带F1，比特组Z2对应频带F2。比特组Z1包括的k个比特与频带F1所对应的k个迷你时隙或符号一一对应，比特组Z2包括的k比特与频带F2所对应的k个迷你时隙或符号一一对应。比特组Z1包括的k个比特用于指示与频带F1所对应的k个迷你时隙或符号是否被重分配，比特组Z2包括的k个比特用于指示与频带F2所对应的k个迷你时隙或符号是否被重分配。以每个时域调度单位包括7个符号，即k＝7为例，每个公共后资源指示信息可以包括2个比特组，每个比特组可以包括7个比特，按照符号的索引大小，比特组Z1的7个比特依次指示频域位于频带F1的第1个至第7个符号是否被重分配；比特组Z2的7个比特依次指示频域位于频带F2的第1个至第7个符号是否被重分配。进一步地，比特值为0可以指示相应地频带上对应的迷你时隙或符号被重分配，比特值为1指示相应地频带上对应的迷你时隙或符号未被重分配。或者，比特值为1可以指示相应地频带上对应的迷你时隙或符号被重分配，比特值为0指示相应地频带上对应的迷你时隙或符号未被重分配。
因此，网络设备可以通过发送包括X个包括(q*k)个原始比特的公共后资源指示信息指示PDCCH调度的时频资源中被重分配的时频资源。
当y不为0时，例如y＝2时，表示每个时域调度单位在时域上包括的k个迷你时隙或符号中的前2个迷你时隙或符号固定不用于重分配。此时，与每个时域调度单位包括的k-2个迷你时隙或符号对应的k-2个比特用于指示相应频带上对应地时域调度单位中的第3个至第k个迷你时隙或符号中被重分配的时频资源。具体地，可以参照上文中y＝0时的描述，为了简洁，此处不再赘述。
因此，网络设备可以通过发送包括X个包括(q*(k-y))个原始比特的后资源指示信息指示PDCCH调度的时频资源中被重分配的时频资源。
可选地，每个时域调度单位包括公共时频资源，其中，第i个时域调度单位中的公共时频资源被在所述第i个时域调度单位中被调度的部分或全部终端设备接收，i∈[1，N]，N为所述时频资源在时域上包括的时域调度单位的数量。
具体来讲，所述时频资源即网络设备调度的时频资源在时域上包括一个或多个时域调度单位。换句话说，网络设备调度的时域资源包括一个或多个时域调度单位。每个时域调度单位可以只包括网络设备调度的一个普通终端的时域资源，也可以包括网络设备调度的多个普通终端的时域资源。每个时域调度单位包括在该时域调度单位中被调度的全部或部分终端设备的公共时频资源，在该时域调度单位中被调度的全部或部分终端设备可以在该公共时频资源上接收与该时域调度单位对应的后资源指示信息。
本申请实施例的无线通信的方法，终端设备通过检测分配给该终端设备的时频资源所属的时域调度单位对应的公共资源指示信息，可以确定分配给该终端设备的时频资源中是否有被重分配的时频资源，以及分配给该终端设备的时频资源中被重分配的时频资源。从而，终端设备可以只接收(例如，解码或解调)承载于没有被重分配的时频资源上的数据，不接收(例如，不解码或不解调)承载于被重分配的时频资源上的数据，实现下行数据的正确接收。因此，本申请实施例的无线通信的方法，能够减小由于资源重分配造成的终端设备的接收性能损失。

具体地说，在本申请实施例中，将PDCCH所指示的时频资源中发生重分配的终端设备记做：终端设备Tβ，即，该终端设备Tβ所使用的由PDCCH指示的部分或全部时频资源被重分配，或者说，该终端设备Tβ可以是上述时频资源#M的原始(或者说，重分配前)的分配对象。其中，该终端设备Tβ所的数量可以是一个也可以是多个，本申请并未特别限定。
需要说明的是，在本申请实施例中，针对各终端设备Tβ的处理过程可以相似，这里为了便于理解和说明，以该终端设备Tβ中的一个终端设备(记做：终端设备Tβ#1)的处理过程为例，进行说明。
具体地说，网络设备确定终端设备Tβ#1所使用的由PDCCH指示的时频资源中被重分配的时频资源(以下，为了便于理解和区分，记做：时频资源#Mβ#1)。
其后，网络设备可以生成用于指示该时频资源#Mβ#1的指示信息(即，专用后资源指示信息的一例)，以下，为了便于理解和区分，记做：专用后资源指示信息Hβ#1。
并且，该网络设备可以通过由PDCCH调度给该终端设备Tβ#1的时频资源(以下，为了便于理解，记做，时频资源Tβ#1)将该专用后资源指示信息Hβ#1发送至终端设备Tβ#1，从而，终端设备Tβ#1可以根据该专用后资源指示信息Hβ#1，确定该时频资源#Mβ#1被重分配，从而，该终端设备Tβ#1可以不接收(例如，不解码或不解调)承载于时频资源#Mβ#1上的数据
下面，对承载专用后资源指示信息Hβ#1的时频资源在时频资源#Tβ#1中的时域位置进行说明。
例如，可选地，每个专用后资源指示信息承载于所述PDCCH指示的分配给所对应的终端设备的后N个符号，N≥1。
具体地说，作为示例而非限定，对承载该专用后资源指示信息Hβ#1的时频资源在该时频资源#Tβ#1中位于最末尾的M个符号。
应理解，以上列举的承载该专用后资源指示信息Hβ#1的时频资源在该时频资源#Tβ#1中的位置仅为示例性说明，本申请并未限定于此，承载该专用后资源指示信息Hβ#1的时频资源在该时频资源#Tβ#1中的位置可以是任意的，并且，承载该专用后资源指示信息Hβ#1的时频资源(例如，符号)的数量也可以是任意确定的，并且，当承载该专用后资源指示信息Hβ#1的时频资源包括多个符号时，该多个符号可以是连续的也可以是不连续的，本申请并未特别限定。
可选地，承载专用后资源指示信息Hβ#1的RE数目可以随编码速率的变化而变化。
图5示出了本申请实施例的一个进行资源重分配的时频资源的示意图。如图5所示，终端设备T1#1的专用后资源指示信息H1#1在时域上位于分配给终端设备T1#1的时频资源#T1#1的最后一个符号。终端设备T2#1的专用后资源指示信息H2#1在时域上位于分配给终端设备T2#1的时频资源#T2#1的最后两个符号。
可选地，当分配给终端设备Tβ的频带小于一定载波数目时，例如，小于72个子载波或者48个子载波或者36个子载波时，专用后资源指示信息Hβ#1可以占用时频资源Tβ#1的最后两个符号。
可选地，根据终端设备Tβ#1的时频资源Tβ#1内的最后一个符号至倒数第二个符号的方向，专用后资源指示信息Hβ#1可以按照从最后一个符号的最小序号子载波向最大序号方向排布，或专用后资源指示信息Hβ#1可以按照从最后一个符号的最大序号子载波向最小序号方向排布。
图6示出了本申请实施例的一个进行资源重分配的时频资源的示意图。如图6所示，终端设备T1#1的专用后资源指示信息H1#1在时域上位于时频资源#T1#1的最后一个符号。终端设备T2#1的专用后资源指示信息H2#1根据分配给终端设备T2#1的时频资源#T2#1的最后一个符号至倒数第二个符号的方向，按照从最后一个符号的最小序号子载波向最大序号方向排布。
可选地，本申请实施例中，分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源在频域上对应z个频段，第J个专用后资源指示信息包括z个比特组，所述z个频段与所述z个比特组一一对应，每个比特组包括p-s个比特，对于频段Dr所对应的比 特组Ur，比特组Ur中的p-s个比特与频段Dr所对应的p-s个迷你时隙或符号一一对应，比特组Ur中的比特的比特值用于指示与频段Dr所对应的分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源在时域上的后p-s个迷你时隙或符号是否被重分配，其中，s≥0，p≥0，z≥1，p>s，r∈[1，p]，p为分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源在时域上包括的迷你时隙或符号的数量。
具体地，z＝1且s＝1时，分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源在频域上可以对应一个频段D1，该频段D1是分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源的频域资源。此时，第J个专用后资源指示信息可以包括一个比特组U1，比特组U1包括的p个比特与p个迷你时隙或符号一一对应。p个比特的比特值可以用于指示分别占频段D1的p个迷你时隙或符号是否被重用。举例来说，分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源在时域上包括6个符号，即p＝6时，第J个专用后资源指示信息可以包括6个比特。按照符号的索引大小，6个比特依次指示第1个至第6个符号是否被重分配。比特的比特值为0可以指示对应的符号或迷你时隙被重分配，比特的比特值为1可以指示对应的符号或迷你时隙未被重分配。或者，比特的比特值为1可以指示对应的符号或迷你时隙被重分配，比特的比特值为0可以指示对应的符号或迷你时隙未被重分配。
当z＞1且s＝1时，以z＝2为例进行说明。分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源在频域上对应2个频带，也就是说，分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源的频域资源可以分为2个频段，即频带D1和频带D2。此时，第J个专用后资源指示信息可以包括2个比特组，比特组U1对应频带D1，比特组U2对应频带D2。比特组U1包括的p个比特与频带D1所对应的p个迷你时隙或符号一一对应，比特组U2包括的p比特与频带D2所对应的p个迷你时隙或符号一一对应。比特组U1包括的p个比特用于指示与频带D1所对应的p个迷你时隙或符号是否被重分配，比特组U2包括的p个比特用于指示与频带D2所对应的p个迷你时隙或符号是否被重分配。以分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源在时域上包括7个符号，即p＝7为例，第J个专用后资源指示信息可以包括2个比特组，每个比特组可以包括7个比特，按照符号的索引大小，比特组U1的7个比特依次指示频域位于频带D1的第1个至第7个符号是否被重分配；比特组U2的7个比特依次指示频域位于频带D2的第1个至第7个符号是否被重分配。进一步地，比特值为0可以指示对应的迷你时隙或符号被重分配，比特值为1指示对应的迷你时隙或符号未被重分配。或者，比特值为1可以指示对应的迷你时隙或符号被重分配，比特值为0指示对应的迷你时隙或符号未被重分配。
因此，网络设备可以通过发送包括z*p个原始比特的专用后资源指示信息指示PDCCU调度的一个终端设备的时频资源中被重分配的时频资源。
当s不为0时，例如s＝1时，表示分配给所述第J个专用后资源指示信息所对应的终端设备的时频资源在时域上包括的p个迷你时隙或符号中的前1个迷你时隙或符号固定不用于重分配。
因此，网络设备可以通过发送包括z*(p-s)个原始比特的专用后资源指示信息指示PDCCU调度的一个终端的时频资源中被重分配的时频资源。
本申请实施例中，终端设备通过检测承载在PDCCH指示的分配给该终端设备的时频资源上的专用后资源指示信息，可以确定分配给该终端设备的时频资源中是否有被重分配的时频资源，以及分配给该终端设备的时频资源中被重分配的时频资源。进而在下行传输时，终端设备可以只对承载在分配给该终端设备的时频资源中未被重分配的时频资源上的下行数据进行解调或解码，实现下行数据的正确接收。因此，本申请实施例的无线通信的方法，能够减小由于资源重分配造成的终端设备的接收性能损失。
应理解，本申请实施例涉及的后资源指示信息，例如，公共后资源指示信息、专用后资源指示信息，可以包括对前文所述的比特(原始比特)编码调制后的比特以及一起发送的导频信道等。
作为本申请的另一实施例，在终端设备接收对应的PDCCH之前，该方法还可以包括：终端设备接收网络设备发送的指示信令。指示信令可以用于指示可被重分配的频域资源；指示信令还可以用于指示终端设备是否需要接收后资源指示信息。终端设备可以是在当前调度周期内被调度的各终端设备。
进一步地，终端设备可以接收网络设备发送的系统信息或无线资源控制RRC信令或媒体接入控制控制单元(Media Access Control Control Element，MAC CE)，系统信息可以承载指示信令，或RRC层信令可以承载指示信令，或MAC CE可以承载指示信令。
在指示信令指示PDCCH调度的时频资源中可被分配的频域资源时，具体地，指示信令可以包括下行资源块分配字段。指示信令中的下行资源块分配字段可以用于指示可被重分配的资源块的起始位置和终止位置，或，指示信令中的下行资源块分配字段可以用于指示可被重分配的资源块的起始位置和数目。普通终端通过读取指示信令中的下行资源块分配字段，可以确定在PDCCH调度的时频资源是否包括可以被重分配的频域资源。
另外，指示信令可以用于指示整个载波的频域资源是否可以被重分配。进一步地，终端设备还可以接收网络设备发送的系统信息或广播信道，系统信息可以承载指示信令，或广播信道可以承载指示信令。
示例地，指示信令可以包括一个比特，该比特可以称为第一比特。第一比特的比特值可以指示整个载波是否可被重分配。举例来说，第一比特为0时，指示整个载波可以被重分配，第一比特为1时，指示整个载波都不会被重分配。或者，第一比特为1时，指示整个载波可以被重分配，第一比特为0时，指示载波都不会被重分配。
图7和图8出了本申请实施例的一个进行资源重分配的时频资源的示意图。
指示信令可以通过下行资源块分配字段，指示整个可以被分配的频域资源可以被重分配的频域资源。如图7示出了指示信令指示的整个载波中可被重分配的频域资源#1。
指示信令中的第一比特为0时，指示整个载波可被重分配。如图8示出了指示信令指示的整个可被重分配的频域资源中可被重分配的频域资源#2。
可选地，指示信令可以指示终端设备是否需要接收后资源指示信息，其中，所述指示信令可以由RRC层信令承载。此时，在终端设备接收网络设备发送的后资源指示信息之前，终端设备还需要确定是否需要接收后资源指示信息。在终端设备确定需要接收后资源指示信息时，终端设备可以接收后资源指示信息。
进一步地，指示信令可以包括一个比特，这个比特可以称为第二比特。第二比特的比特值可以指示普通终端是否需要接收后资源指示信息。举例来说，第一比特为0时，指示 普通终端不需要接收后资源指示信息，直至网络设备重新配置；第一比特为1时，指示普通终端需要接收后资源指示信息，直至网络设备重新配置。或者，第一比特为1时，指示普通终端不需要接收后资源指示信息，直至网络设备重新配置；第一比特为0时，指示普通终端需要接收后资源指示信息，直至网络设备重新配置。
可选地，PDCCH还可以指示终端设备是否需要接收后资源指示信息。终端设备在接收到PDCCH后，根据PDCCH可以确定是否接收后资源指示信息。当终端设备根据PDCCH确定接收后资源指示信息时，终端设备可以接收后资源指示信息。
图9是根据本申请提供的另一无线通信的方法的示意性流程图。
S610，网络设备发送指示信令。相应地，终端设备接收网络设备发送的指示信令。
指示信令可以用于指示可被重分配的频域资源。指示信令还可以用于指示终端设备是否需要接收后资源指示信息。具体地可以参照前文中的描述，为了简洁，此处不再赘述。
S620，终端设备根据指示信令确定是否接收后资源指示信息。
具体地，在指示信令指示整个可以被分配的频域资源不被重分配时，或者指示信令指示终端设备不需要接收后资源指示信息时，终端设备确定不需要接收后资源指示信息。
S630，网络设备发送PDCCH。相应地，终端设备接收网络设备发送的PDCCH。
具体地，该步骤可以参照S210的描述，为了简洁，此处不再赘述。
需要说明的是，S620和S630可以同时执行，也可以先执行S630，再执行S620，本申请实施例对此不作限定。

具体地，该步骤可以参照S220的描述，为了简洁，此处不再赘述。
S650，网络设备发送物理下行共享信道(Physical Downlink Share Channel，PDSCH)。
具体地，网络设备在PDCCH指示的分配给该终端设备的时频资源中的未被重分配的时频资源上发送PDSCH。需要注意的是，本申请不限制步骤S640和步骤S650的顺序，步骤S650可以先于步骤S640，步骤S640也可以步骤S650实施的过程中实施。
S660，网络设备向终端设备发送后资源指示信息。
后资源指示信息可以参照上文中的描述，为了简洁，此处不再赘述。因为重调度动作是在给普通终端发送下行数据过程中做出的，因此S650和S660的执行顺序可以不分先后。
网络设备发送的后资源指示信息，终端设备可能接收也可能不接收。具体地，当在S620中终端设备确定不接收后资源指示信息时，则终端设备不接收该后资源指示信息。或者，因为仅仅占用了靠近PDCCH的几个符号的PDSCH可以满足紧急终端设备的业务，没有必要再进行重分配。所以，当终端设备根据S640中接收的PDCCH，获知PDSCH的结束符号距离PDCCH结束符号仅有w个符号时，终端设备不接收该后资源指示信息。w大于等于1。例如，w可以是2或3。
在S620中终端设备确定接收后资源指示信息，或者标准规定终端设备需要接收后资源指示信息时，终端设备接收后资源指示信息。
S670，终端设备确定PDCCH指示的分配给该终端设备的时频资源中被重分配的时频资源。
具体地，当终端设备确定需要接收后资源指示信息时，终端设备接收后资源指示信息。并且，终端设备可以根据PDCCH和该后资源指示信息，确定PDCCH指示的分配给该终 端设备的时频资源中有没有被重分配的时频资源，以及被重分配的时频资源有哪些。
S680，终端设备对PDSCH进行解调或解码。
具体地，在终端设备确定PDCCH指示的分配给该终端设备的时频资源中有没有被重分配的时频资源，以及被重分配的时频资源有哪些后，终端设备可以只对承载在分配给该终端设备的时频资源中未被重分配的时频资源上的PDSCH进行解调或解码，实现下行数据的正确接收，从而能够减小由于资源重分配造成的终端设备的接收性能损失。
在图9所示的无线通信的方法中，在标准规定所有终端设备都需要接收指示信令时，则网络设备可以不执行S610，相应地，终端设备也不需要接收指示信令。
图10是根据本申请提供的另一无线通信的方法的示意性流程图。

具体地，该步骤可以参照S210的描述，为了简洁，此处不再赘述。
S720，终端设备根据PDCCH确定是否接收后资源指示信息。
具体地，PDCCH还可以用于指示终端设备是否需要接收后资源指示信息。在终端设备根据PDCCH确定需要接收后资源指示信息时，才接收后资源指示信息，否则不接收。
S730，网络设备对PDCCH调度的时频资源中的至少一个时频资源进行重分配。
具体地，该步骤可以参照S220的描述，为了简洁，此处不再赘述。
需要说明的是，S720和S730的执行顺序可以不分先后。
S740，网络设备发送物理下行共享信道(Physical Download Share Channel，PDSCH)。
具体地，网络设备在PDCCH指示的分配给该终端设备的时频资源中的未被重分配的时频资源上发送PDSCH。
S750，网络设备向终端设备发送后资源指示信息。
后资源指示信息可以参照上文中的描述，为了简洁，此处不再赘述。因为重调度动作是在给普通终端发送下行数据过程中做出的，因此S740和S750的执行顺序可以不分先后。
网络设备发送的后资源指示信息，终端设备可能接收也可能不接收。具体地，当在S720中终端设备确定不接收后资源指示信息时，则终端设备不接收该后资源指示信息。在S720中终端设备确定接收后资源指示信息，或者标准规定终端设备需要接收后资源指示信息时，终端设备接收后资源指示信息。
S760，终端设备确定PDCCH指示的分配给该终端设备的时频资源中被重分配的时频资源。
具体地，当终端设备确定需要接收后资源指示信息时，终端设备接收后资源指示信息。并且，终端设备可以根据PDCCH和该后资源指示信息，确定PDCCH指示的分配给该终端设备的时频资源中有没有被重分配的时频资源，以及被重分配的时频资源有哪些。
S770，终端设备对PDSCH进行解调或解码。
具体地，在终端设备确定PDCCH指示的分配给该终端设备的时频资源中有没有被重分配的时频资源，以及被重分配的时频资源有哪些后，终端设备可以只对承载在分配给该终端设备的时频资源中未被重分配的时频资源上的PDSCH进行解调或解码，实现下行数据的正确接收，从而能够减小由于资源重分配造成的终端设备的接收性能损失。
本申请的无线通信的方法中，紧急终端设备可以确定所述后资源指示信息的时频位置，即使最后一个时域单位被重新分配，紧急终端也会避让后资源指示信息所在的时频资 源。在一个实施例中，当PDCCH调度的时频资源均被重新分配时，网络设备可以不发送后资源指示信息，同时网络设备向紧急终端设备发送指示，指示终端设备无需避让。在另一实施例中，在普通终端设备检测后资源指示信息发生错误时，那么普通终端认为后资源指示信息指示的时频资源均已被重新分配。
图11示出了本申请实施例的网络设备800的示意性框图。如图11所示，网络设备800包括：发送单元810、处理单元820和接收单元830。
