Description

通信方法和通信设备
本申请要求于2017年05月18日提交中国专利局、申请号为201710354921.1、发明名称为“通信方法和通信设备”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
本申请涉及通信技术领域，尤其涉及一种无线通信系统中通信的方法和通信设备。
背景技术
在通信系统中，下行通信是指基站向终端设备发送信息，上行通信是指终端设备向基站发送信息。下行通信包括但不限于基站向终端设备发送下行数据，上行通信包括但不限于终端设备向基站发送上行数据。在下行数据传输前，基站需要向终端设备发送下行控制信息(Downlink Control Information，DCI)以指示终端设备进行数据的接收。基站经过信道编码等一系列操作，将DCI承载于物理下行控制信道(Physical downlink control channel，PDCCH)，并向终端设备发送。并且，如果终端设备需要向基站传输上行数据，基站需要授权终端设备如何进行上行传输，这种授权也是通过DCI通知给终端设备的。
因为控制信息的重要性很高，往往会采用较低的码率和低阶调制方式来传输，以保证其稳健性。其中，码率通常是指传输比特中有效信息比特的占比。例如将20比特信息编码成60比特，码率为1/3，码率越低信道编码能提供的保护和纠错能力越强。调制，是指将比特调制成符号。例如对于正交相移键控(quadrature phase shift keying，QPSK)符号，通过调制，将2比特调制成1个QPSK符号；对于256正交幅度调制(quadrature amplitude modulation，QAM)符号，通过调制，将8个比特调制成一个256QAM符号。调制的阶数越低，传输的错误概率就越小。
在通信中，往往将一个符号映射到一个时频资源基本单元上。基站发送DCI所需的时频资源与DCI的长度成正比，即DCI的长度越长，占用的时频资源会越多。而控制信道的时频资源是有限的，大部分的时频资源需要留给数据的传送。现有技术中，DCI所包含的用于指示分配给终端设备的资源信息的长度过长，占用的比特位过多，导致因指示资源分配信息占用的时频资源较多。

资源块(Resource block，RB)是RE组合后的资源块。以LTE为例，每个资源块包括频域的12个连续子载波和时域0.5ms的一个时隙。
DCI是二进制的比特流，被调制之后为QPSK符号。多个子载波的QPSK符号经过快速傅里叶逆变换(Inverse fast Fourier Transform，IFFT)成为正交频分多址(orthogonal frequency division multiplexing，OFDM)波形，一个单位时间内的OFDM波形称为一个OFDM符号。
通常情况下，DCI中包括的字段或信息包括但不限于：资源分配头(Resource allocation header)，资源块分配(Resource block assignment)，调制和编码(modulation and coding scheme)，混合自动重传请求(Hybrid automatic repeat request，HARQ)进程号(HARQ process number)，新数据指示(New data indication)，冗余版本(Redundancy version)和多天线传输相关控制信息等。并且，基于传输模式的不同，DCI携带的内容也不同，因此DCI会有不同的格式。每一个DCI由很多个字段构成，每种格式的DCI的组成字段可能不同，DCI的长度也可能不同。
DCI中资源分配头和资源块分配字段用于表示资源分配相关的信息。资源分配相关的信息用于指示终端设备哪些时频资源是调度给终端设备用来进行数据传输的。资源分配头字段用于表示终端设备资源分配的方式(Resource allocation type，RA type)，资源块分配字段用于表示终端设备具体调度的频域资源。
在LTE中，RA type有三种，分别是RA type 0、RA type 1和RA type 2，不同的DCI格式会使用不同的RA type。基站可以通过显式或隐式的方式，通知终端设备该DCI使用的RA type。显式通知是用DCI中的资源分配头字段表示RA type的信息。隐式通知是预先设定某些DCI只使用某种RA type，例如只使用RA type 2，这时就不需要使用资源分配头字段表示RA type的信息。
资源块分配字段与资源分配方式有关，基站在DCI中的资源块分配字段表示分配给终端设备的时频资源时，因具体的资源分配方式的不同而不同。具体如下：
当使用RA type 0时，使用bitmap方式指示频域内独立连续的资源块组(RBG)。相对于直接使用资源块(RB)，使用资源块组可以实现bitmap比特数目的减少。Bitmap的长度可以由

计算，其中
Figure PCTCN2018087542-appb-000002
是上取整符号，
Figure PCTCN2018087542-appb-000003
是系统带宽(以RB为单位)。分组的大小P取决于系统带宽。
图1(a)为资源分配方式为RA type 0时使用bitmap方式指示时频资源分配的一种实现方式示意图。假设系统带宽为25个RB，P＝2，则RBG为13个。图1(a)中阴影部分表示被分配的资源块组。相应的，资源块分配字段为{1001110001010}。
当使用资源分配方式1时，是将资源块组分为P个子集。具体来说资源分配方式1使用三个字段来指示分配的时频资源。第一个字段长度为
Figure PCTCN2018087542-appb-000004
用于表示选择的子集，即选择第0≤p＜P个资源块组子集。第二个字段长度为1个比特，用于表示是否有偏移量Δ shift(p)。其中，偏移量
Figure PCTCN2018087542-appb-000005
第三个字段是一个bitmap，其中的每一个比特是指所选资源块组子集中的每一个资源块是否被分配。第三个字段长度为
Figure PCTCN2018087542-appb-000006
图1(b)为资源分配方式1时指示频域内资源分配的一种实现方式示意图。仍以系统带宽为25个RB，P＝2为例进行说明。图1(b)中，RA type 1(b1)所示的第二字段为0，即无偏移量，Δ shift(p)＝0的例子，资源分配用二进制表示为{0010011101000}。RA type 1(b2)所示的第二字段为1，即偏移量Δ shift(p)＝2，资源分配用二进制表示为{0110011101000}。
当使用资源分配方式2时，是使用资源块分配的起始位置和长度来表示分配的时频资源的信息。具体来说，是使用一个resource indication value(RIV)，其是起始位置RB start和长度L CRBs的函数，即：
Figure PCTCN2018087542-appb-000007
图1(c)为资源分配方式2时指示频域内资源分配的一种实现方式示意图。以系统带宽为25个RB为例，如图1(c)所示，资源分配从(第6个RB开始，长度为9个RB)可以用RIV＝206来表示。RA type 2时资源分配指示可以用长度为
Figure PCTCN2018087542-appb-000008
的二进制序列表示。图1(c)所示资源分配用二进制表示为{011001110}。
上述三种资源分配方式中，资源块分配字段占用了大量的比特位，导致资源开销较大。以上述25个RB的带宽为例，采用RA type 0时，资源块分配字段需要13个比特；采 用RA type 1时，资源块分配字段需要13个比特；采用RA type 2时，资源块分配字段需要9个比特。对于5G NR，特别是高频通信中，其带宽比LTE大数倍，资源块分配字段将会占用更多的时频资源。例如在第一种资源分配方式中，需要13个比特才能表示出资源块的分布。该13个比特通过1/3码率信道编码则是39个比特。在不考虑速率匹配的情况下，通过QPSK也需要使用20个QPSK符号。每一个QPSK占一个RE，那么资源块分配总共需要20个RE的开销，造成了时频资源的浪费。在考虑速率匹配的情况下，实际传输码率变高，即有效信息比特的占比变高，传输的错误率变高。
本申请实施例提供一种通信方法，可以减少控制信息中资源分配信息占用时频资源。
在本申请实施例提供的第一种可能的实现方式中，基站发送的DCI中包括用于指示分配给终端设备的频域资源的标识，该标识用于指示分配给终端设备的频域资源的信息。例如，该标识可以用于指示分配的频域资源是基站能够分配的全部频域资源，也可以用于指示分配的频域资源是基站能够分配的全部频域资源中的部分频域资源。例如，在一种可能的实现方式中，可用的频域资源被划分为K等份，其中K为大于1的整数，如K＝2或者3，或者4等，在基站发送给终端设备的控制信息中，可以分次携带其中的一份或者多份。例如，基站可以预先将可用的频域资源划分为4等份，在每次向终端设备发送的DCI中包括将基站能够分配的全部频域资源划分为4等份后的其中一份。在另一种可能的实现方式中，可用的频域资源可以被不规则划分成不同份，所述标识用于指示分配给终端设备的频域资源是所述可用的频域资源中的部分，例如1/5份或者3/5份等等。
基站在通过控制信息(例如DCI)指示为终端设备分配的频域资源的信息时，由于对频域资源进行预先划分，，基站可以用一个或两个标识来指示分配给终端设备的频域资源。所述对频域资源进行预先划分，可以是通过基站预先划分，标准协议规定，或者基站与终端设备协商等方式来确定频域资源的划分方式。由于标识占用较少的比特数，能够有效减少资源分配信息对时频资源的占用。例如，可以用1个比特的标识(例如DCI中的资源分配头字段)表示分配给终端设备的频域资源为全部的可用频域资源；也可以用1个比特的标识(例如DCI中的资源分配头字段)表示分配给终端设备的频域资源是全部的可用频域资源的一部分(例如可用频域资源的1/4)，而用另一个标识(例如DCI中的资源块分配字段)来表示分配给终端设备的频域资源是4份中的哪一份。这里，所述资源块分配字段用于表示分配给终端设备的频域资源是被划分为4份的频域资源中的其中一份，可以占用1个比特位或2个比特位。本实施方式中，通过一个或多个标识来指示为终端设备分配的资源，能够减少控制信息占用的比特位，生成控制信息所需的时间也会相应越少，提高了效率。
在一种实现方式中，上述频域资源的划分方式，可以是预先确定一种频域资源的划分方式固定不变，例如，基站能否分配的全部频域资源(或可用频域资源)。在另一种实现方式中，上述频域资源的划分方式，也可以是在某一个时间段内相对固定，在不同的时间段内变化的。例如在时间点T1，划分方式可以是基站能够分配的全部频域资源，在时间点T2划分方式可以是将基站能够分配的全部频域资源划分为4等份，在时间点T3选择的划分方式是将基站能够分配的全部频域资源划分为1/5、3/5和1/5等。这样，能够方便使用标识表示分配的频域资源的信息。
这种实现方式适用于基站发送的一个波束所覆盖的终端设备较少的情况。当一个波束覆盖的终端设备较少时，基站在调度资源时可以将能够分配的频域资源都分配给一个终端设备或较少的几个终端设备。可选的，基站将能够分配的频域资源分配给较少的几个终端设备时，频域资源的划分方式可以是变化的划分方式，也可以是不变的划分方式。
本申请中，基站能够分配的全部频域资源，有时也可以称为可用的频域资源，或可分配的频域资源，例如可以是终端设备能够支持的一个载波内的全部频域资源、终端设备能够支持的一个载波内的全部带宽、基站能够分配的一个载波内的全部频域资源、或者基站能够分配的一个载波内的全部带宽。例如，一个载波具有一定的带宽(例如20MB赫兹)，该载波所对应的全部频域资源为基站能够分配的全部频域资源；或者，一个载波的带宽体现为RB数，例如20MB赫兹对应100个RB，该100个RB对应的频域资源为基站能够分配的全部频域资源。不同的终端设备的能力可能不同，不同的终端设备所支持的载波内的频域资源或带宽也会不同。例如一个终端设备在一个载波内能支持最大20MB的带宽，另一个终端设备在一个载波内能支持最大80MB的带宽。因此对于不同的终端设备，基站能够分配的全部频域资源可能是不同的。
下面以基站将能够分配的全部频域资源都分配给终端设备为例进行说明。例如，一个波束覆盖了两个终端设备，终端设备1被分配的频域资源是两个符号对应的全部频域资源，终端设备2被分配的频域资源是三个符号对应的全部频域资源。这时，基站发送的DCI中资源分配头字段可以用1个比特来表示所分配的频域资源的标识，该标识用于指示分配给终端设备的频域资源是所述基站能够分配的全部频域资源。
如图2所示，图2为本申请实施例中分配的时频资源的一种分布结构示意图。图2的横轴方向代表时域资源，纵轴方向代表频域资源。其中，横轴方向的一个方格代表一个符号所对应的时域资源，一个符号所对应的纵轴方向的所有方格代表一个符号对应的全部频域资源。图2中，基站分配给终端设备1的频域资源是两个符号对应的全部频域资源，分配给终端设备2的频域资源是三个符号对应的全部频域资源。因为分配给每个终端设备的频域资源都是基站能够分配的全部频域资源，在DCI的资源分配头字段，可以用1个比特来表示该信息，即可以用1个比特来表示分配给终端设备的频域资源的标识，该标识用于指示分配给终端设备的频域资源是基站能够分配的全部频域资源。
可选的，用于表示分配的频域资源的资源分配头字段也可以是2个比特，本申请实施例不限定用于表示分配给终端设备的频域资源的标识所占用的比特数。只要DCI中用于表示资源分配信息的字段的总的比特数有所缩小，能够减少用于指示时频资源的信息对时频资源的占用，都属于本申请实施例覆盖的范围。并且，由于缩短了控制信息占用的比特位，生成控制信息所需的时间也会相应越少，提高了效率。
同时，在图2所示的实现方式中，当用1个比特在资源分配头字段表示分配给终端设备的频域资源的标识时，还需要在DCI中指示分配给每个终端设备的时域资源的信息。这样，在DCI中既包含了分配给终端设备的频域资源信息，也包含了分配给终端设备的时域资源信息，终端设备能够根据DCI中指示的资源信息准确地获取被分配的时频资源。分配给终端设备的时域资源的信息，既可以是分配给终端设备的开始符号和符号长度的信息，也可以是分配给终端设备的开始符号和结束符号的信息，还可以是符号长度和结束符号的信息。本申请实施例不限定具体的指示时域资源信息的方式，只要终端设备能 够获取具体的时域资源信息即可。
下面以基站在DCI中指示分配给终端设备的频域资源是基站能够分配的全部频域资源且分配给终端设备的时域资源是开始符号和符号长度为例，对基站发送的DCI中关于资源分配的方式进行说明。如图3(a)所示，图3(a)为基站向终端设备发送的DCI中关于资源分配的各字段和相应比特长度的一种对应表。
图3(a)中，资源分配头字段占用1个比特，用以表示分配给终端设备的频域资源的标识，该标识用于指示此次资源分配的类型，即分配给终端设备的频域资源是基站能够分配的全部频域资源。数据信道开始的符号字段占用2个比特，即数据信道占用的时域资源开始的符号字段占用2个比特，用以指示分配给终端设备的时域资源开始的符号；数据信道所占据的符号长度字段占用2个比特，即数据信道占用的时域资源所占据的符号长度字段占用2个比特，用以指示分配给终端设备的时域资源符号的长度。这样，终端设备能够根据DCI中这些字段所指示的信息，获取基站分配的具体的时频资源的信息。
图3(a)中，DCI中用于表示资源分配的频域资源的信息的字段共占用5(1+2+2)个比特，小于上述13或9个比特，能够节省资源分配的信息所占用的时频资源；生成控制信息所需的时间也会相应越少，提高了效率。相应的，终端设备在获取到控制信息时，因为由于缩短了控制信息占用的比特位，解析控制信息所需的时间也会相应越少，提高了效率。
需要说明的是，图3(a)中数据信道开始的符号字段和数据信道所占据的符号长度字段所需要的比特的位数可以通过
Figure PCTCN2018087542-appb-000009
获取。其中，
Figure PCTCN2018087542-appb-000010
表示一个下行调度单位(本实施例中为时隙)中的符号数；G表示颗粒度，即最小可以分配多少个符号；Log 2表示取以2为底的对数。
另一种时域资源分配的表示方式，例如，可以用一个字段，例如可以用符号分配字段来表示分配的时域资源。该字段表示分配的时域资源的一种可能的实现方式如下：
使用一个time resource indication value(TRIV)，其是起始符号S start和符号长度L S的函数，该函数可以是：
Figure PCTCN2018087542-appb-000011
where L S≥1 and shall not exceed
Figure PCTCN2018087542-appb-000012
其中，
Figure PCTCN2018087542-appb-000013
是一个子帧/时隙内的符号数。
可以理解，一个子帧/时隙内的符号数
Figure PCTCN2018087542-appb-000014
可以是固定值，该固定值可以为系统预定义的。，例如，
Figure PCTCN2018087542-appb-000015
可以为6、7、12或14等。以
Figure PCTCN2018087542-appb-000016
为14为例，上述函数可以表示为：
if(L S-1)≤7 then
TRIV＝14·(L S-1)+S start
else
TRIV＝14·(14-L S+1)+(14-1-S start)；
Where 0<L S<14-S start。需要说明的是，TRIV＝14·(L S-1)+S start或者TRIV＝14·(14-L S+1)+(14-1-S start)仅为一种数学表达式举例。可以理解，基于该数学表达式可以有多种等效数学变形。例如，TRIV＝14·(L S-1)+S start还可以表示为TRIV＝14·L S-14+S start，或者TRIV＝14·L S+S start-14。又例如，TRIV＝14·(14-L S+1)+(14-1-S start)，还可以表示为TRIV＝14·(15-L S)+(13-S start)，或者TRIV＝197-14L S-S start)。本发明实施例中对于数学表达式的形式并不作限定，只要TRIV值的结果满足上述数学式的计算结果即可。
可选的，当基站的一个波束只覆盖一个终端设备时，基站可以将所有时频资源分配给终端设备。。DCI中的资源分配相关的信息可以用一个字段(即资源分配头字段)来表示，如图3(b)所示。相应的，终端设备根据DCI中的资源分配头字段，即可获取基站分配的时频资源的信息。
可选的，上述图3(a)或图3(b)的实现方式中，资源分配头字段，占用1个比特用于指示资源分配方式的类型，目的是为了区分其它长度相同的DCI。在具体实现时，基站在确定没有长度相同的DCI时，该字段也可以省去，即不需要资源分配头字段。即可以预先配置分配的频域资源的信息，预先配置为所述终端设备分配的频域资源是所述基站能够分配的全部频域资源。例如可以通过绑定控制信息的格式与分配的频域资源的对应关系预先配置为所述终端设备分配的频域资源。这样，能够进一步减少DCI中指示资源分配信息时所占用的资源。
本申请实施例提供的第二种可能的实现方式中，基站发送的DCI中包括分配给终端设备的时频资源的标识，该标识用于指示分配的时频资源相对于所述终端设备已经获取的有效时频资源变化的信息。这种实现方式适用于基站多次调度相同或相关资源的情况。例如对于高可靠低时延通信(Ultra reliable and low latency communication，URLLC)用户，需要连续多次发送相同数据来提高可靠性的场景。
例如，图4所示的时频资源分配图中，终端设备在时隙n时被分配的时频资源与在时隙n+t1时被分配的时频资源相关，即相对于时隙n偏移了2个RB。其中，n和t1分别是正整数，代表具体的时隙信息。这时，基站在时隙n+t1时发送的DCI中资源分配头字段，可以用1个比特来指示终端设备本次分配的时频资源的标识，该标识用于指示分配的时频资源与终端设备已经获取的有效的时频资源相关；再用一个字段指示终端设备本次分配的时频资源相对于上一次分配的时频资源的偏移量。这样就能够用较少的时频资源指示分配给终端设备的时频资源的信息。
其中，所述终端设备已经获取的有效的时频资源信息，可以是终端设备最近一次获取的有效的时频资源的信息。例如，所述终端设备已经获取的有效的时频资源信息是该终端设备上一次接收到的基站发送的DCI中指示的时频资源信息。
图4中，横轴方向代表时域资源，纵轴方向代表频域资源。其中，横轴方向的一个方格代表一个符号所对应的时域资源，一个符号所对应的纵轴方向的所有方格代表一个符号对应的所有频域资源。在纵轴方向的一个方格代表一个RB资源。
基于图4所示的资源分配方式，基站在发送给终端的DCI中所包括的资源分配相关的字段可以如图5所示。
图5中，资源分配头字段占用1个比特，用以表示分配给终端设备的时频资源的标识，该标识用于指示此次分配的时频资源与已经获取的有效时频资源相关，即与已经获取的有效时频资源有偏移；偏移量字段占用2个比特，用以表示分配的偏移量，该偏移量用于指示本次分配的时频资源相对于已经获取的有效时频资源偏移的值。其中，偏移量字段占用2个比特只是举例，在具体实现时，偏移量字段可以占用1个比特，也可以占用3个比特等，只要能够表示具体的偏移量的信息，都属于本申请实施例保护的范围。
需要说明的是，偏移的方向可以是系统预先定义的，基站和终端设备能够根据预先定义的方向确定所分配的时频资源相对于已经获取的有效的时频资源偏移的方向。例如可以预先定义偏移的方向可以是向RB编号降低的方向，也可以向RB编号增大的方向等。
图5中，DCI中用于表示资源分配相关信息的字段共占用3(1+2)个比特，小于上述13或9个比特，能够节省资源分配的信息所占用的资源。并且，生成控制信息所需的时间也会相应越少，提高了效率。相应的，终端设备在获取到控制信息时，因为由于缩短了控制信息占用的比特位，解析控制信息所需的时间也会相应越少，提高了效率。
作为一种可选的实现方式，所述偏移量也可以是预先定义的偏移量，或通过高层信令通知的方式通知终端设备。在这种情况下，DCI中就可以不包括偏移量的字段。这样，在DCI中可以用1个比特来表示分配的时频资源的标识。
本申请实施例中，所述高层信令包括但不限于MAC-CE或RRC等。
可选的，对于URLLC用户的连续多次发送相同数据的不同版本以提高可靠性的场景，在DCI中也可以不包括偏移量，而是通过复用DCI中已有的字段表示偏移量。即可以利用DCI中已有的字段，例如HARQ进程号字段、新数据指示字段或冗余版本RV字段来表示偏移量。
例如，可以通过RV表示偏移量，也可以通过f(RV)表示偏移量。当通过RV表示偏移量时，偏移量是RV的值。例如RV＝1，则偏移一个RB，RV＝2，则偏移2个RB。。当通过f(RV)表示偏移量时，偏移量是一个RV的函数f()。例如f(x)＝2x。那么M＝2*RV。RV＝1时，则偏移2个RB。
例如，图6(a)为复用RV字段表示偏移量的实现方式，图6(b)为复用HARQ进程号字段表示偏移量的实现方式，图6(c)为复用新数据指示字段表示偏移量的实现方式。需要说明的是，上述被复用的字段，还具有其本身所具备的功能，在其本身所具备的功能之外，还附带具有指示终端设备偏移量的功能。如图6(a)中RV字段除其本身携带的信息之外，还能够指示终端设备具体的偏移量。
可选的，还可以通过波束编号字段携带偏移量，例如编号为1的波束偏移量为1个RB，编号为2的波束，偏移量为2个RB等等。需要说明的是，这里的波束不是物理上的波束，而是逻辑上的波束。
可选的，上述图5、图6(a)、图6(b)或图6(c)中，资源分配头字段，占用1个比特用于表示分配的时频资源的标识，该标识用于指示终端设备此次分配的时频资源与已经获取的有效时频资源相关，目的是为了区分其它长度相同的DCI。在具体实现时，基站在确定没有长度相同的DCI时，该字段也可以省去，即不需要资源分配头字段。这样，能够进一步减少DCI中指示资源分配信息时所占用的资源。
相应的，终端设备可以根据接收到的DCI中的资源分配头字段获取分配的时频资源 与已经获取的有效的时频资源相关，并根据获取到的偏移量，即可获取基站分配的时频资源的信息。
本申请实施例提供的第三种可能的实现方式中，基站发送的DCI中包括分配的时频资源的标识，该标识用于指示分配给终端设备的时频资源与所述终端设备已经获取的有效时频资源相同。这种实现方式适用于基站多次调度相同资源的情况。例如对于URLLC用户，需要连续多次发送相同数据来提高可靠性的场景。
例如，图7所示的时频资源分配图中，终端设备在时隙n时被分配的时频资源与在时隙n+t1时被分配的时频资源相同。其中，n和t1分别是正整数，代表具体的时隙信息。这时，基站在时隙n+t1时发送的DCI中，可以用1个比特表示分配给终端设备的时频资源的标识，该标识用于指示本次分配的时频资源与上一个被分配的有效的时频资源相同。这样能够大大减少DCI中资源分配信息所占用的时频资源。并且，由于缩短了控制信息占用的比特位，生成控制信息所需的时间也会相应越少，提高了效率。相应的，终端设备在获取到控制信息时，因为由于缩短了控制信息占用的比特位，解析控制信息所需的时间也会相应越少，提高了效率。
图7中，横轴方向代表时域资源，纵轴方向代表频域资源。其中，横轴方向的一个方格代表一个符号所对应的时域资源，一个符号所对应的纵轴方向的所有方格代表一个符号对应的所有频域资源。以图7所示的资源分配方式为例，基站在发送给终端的DCI中所包括的资源分配相关的字段可以如图8所示。这样，终端设备可以根据接收到的DCI中的资源分配头字段即可获取分配的时频资源的信息，即分配的时频资源与已经获取的时频资源相同。
可选的，图8中资源分配头字段，占用1个比特用于表示分配给终端设备的时频资源的标识，目的是为了区分其它长度相同的DCI。在具体实现时，基站在确定没有长度相同的DCI时，该字段也可以省去，即不需要资源分配头字段。这样，能够进一步减少DCI中指示资源分配信息时所占用的资源。例如，可以预先配置分配的时频资源的信息，即预先配置为所述终端设备分配的时频资源相对于所述终端设备已经获取的有效时频资源变化的信息。可选的，可以通过绑定控制信息的格式与分配的时频资源相对于所述终端设备已经获取的有效时频资源变化的信息的对应关系预先配置为所述终端设备分配的时频资源。
上述第一种、第二种和第三种实现方式中，基站采用的资源分配方式是预先配置或设定好的。例如，在基站和终端设备之间预先配置上述第一种、第二种和第三种的资源分配方式，基站通过调度算法为终端设备分配资源后，通过DCI将分配的资源信息发送给终端设备，这时可以使用上述第一种、第二种和第三种的资源分配方式。即基站在需要向终端设备发送DCI时，可以根据具体的实现情况，选择上述三种资源分配方式中的一种，并生成DCI发送给终端设备。终端设备接收到基站发送的DCI后，也能够根据预先配置的上述三种资源分配方式，结合获取到的DCI中关于资源分配字段所记载的内容，获取基站所分配的资源信息。
图9为本申请实施例提供的通信设备100的基本结构示意图。如图9所示，通信设备100包括控制信息生成单元102。所述控制信息生成单元102，可以是DCI生成单元102，用于根据通信设备100对资源调度的结果，生成控制信息，例如DCI，所述控制信息中 包括分配给终端设备的资源的信息。在一种实现方式中，通信设备100可以是芯片，例如，基带芯片或通信芯片。所述控制信息生成单元102可以由电路或处理器来实现。在另一种实现方式中，所述通信设备100可以是网络侧设备，例如是基站。所述通信设备100还可以包括发送单元112。所述发送单元112，用于将所述控制信息生成单元102生成的控制信息向终端设备发送。所述发送单元可以是发射机，或发射电路等等。其中，所述控制信息生成单元102所生成的控制信息中包括的分配给终端设备的资源的信息，具体可以参考图2至图7以及上述与2至图7相关的描述，不再赘述。
由于通信设备100在控制信息(例如DCI中)，使用标识来表示资源分配信息，其占用的比特数少，能够减少控制信息中资源分配的信息所占用的时频资源。
图10为本申请实施例提供的通信设备100的一种结构示意图。图10中，通信设备100可以可选的包括以下部分：调度单元101、DCI生成单元102、封装单元120、CRC校验单元103、信道编码单元104、速率匹配单元105、聚合复用单元106、加扰单元107、调制单元108、端口映射109、时频映射单元110、IFFT单元111、发送单元112、接收单元113、快速傅里叶变换(fast Fourier Transform，FFT)单元114、解调单元115、解扰单元116、解码单元117、数据接收单元118和天线119。可以理解，图10中的各个逻辑单元可以是分别单独的设计，也可以是一个或多个集成在一起。
需要说明的是，通信设备100可以包括一个或多个存储器和处理器用于实现如图2至图7中基站的功能。图10中的每个单元可以单独设置存储器和/或处理器。也可以是两个或两个以上的单元公用存储器和/或处理器。通信设备100可以是芯片，也可以是基站设备，本发明并不对此进行限定。其中，调度单元101，用于根据终端设备的信道条件、需要传输的数据大小等进行资源调度。调度的结果包括为终端设备分配哪些时频资源，采用什么调制方式和码率来发送数据，采用什么传输模式发送数据，使用哪些天线端口发送数据等。
DCI生成单元102，用于根据调度单元101调度的结果，生成DCI，生成的DCI中包括为终端设备分配的时频资源、调制方式和码率等信息。DCI生成单元102生成的DCI中，用于表示分配的频域资源和/或时域资源字段，可以参考上述图2、图4和图7描述的实现方式中表示分配的资源的信息方式来实现。这样，通信设备100能够减少在DCI中因表示分配的资源的信息对时频资源占用，提高时频资源的利用率。
封装单元120，用于将调度单元调度的数据封装为预定义的格式。其中，调度的数据是需要发送给终端设备的数据。
CRC校验单元103，用于对DCI生成单元102生成的DCI添加CRC校验比特，或将封装单元120封装后的数据添加CRC校验比特。可选的，在LTE中，CRC校验单元103会根据终端设备的ID添加CRC校验比特，所述终端设备的ID通常为该终端设备的用户在网络中临时身份认证(Radio Network Temporary Identifier，RNTI)。

图11为本申请实施例提供的通信设备200的基本结构示意图。如图11所示，通信设备200包括接收单元201和获取单元209。其中，接收单元201用于接收无线信号；获取单元209用于根据接收单元接收到的无线信号，获取所述无线信号中的分配的资源的信息。具体的，所述接收单元201接收到的无线信号中包括控制信息，所述控制信息中包括分配的时频资源的信息。在一个例子中，所述接收单元201可以是接收机或接收电路等，所述获取单元209可以由处理器实现。通信设备200的实现方式可以参考上述图至图7描述的实现方式中终端设备接收并获取分配的资源的信息的方式来实现，不再赘述。
这样，通信设备200接收到的控制信息(例如DCI中)，用于指示分配的时频资源的信息的字段所占用的比特位少，能够有效节省控制信息(例如DCI)中资源分配相关字段所占用的时频资源。
图12为本申请实施例提供的通信设备200的结构示意图。图12中，通信设备200可以可选的包括以下部分：接收单元201、FFT单元202、解调单元203、解扰单元204、盲检单元205、速率匹配单元206、信道解码单元207、CRC校验单元208、获取单元209、编码单元210、加扰单元211、调制单元212、IFFT单元213、发送单元214和天线215。其中，接收单元201用于在某一个子帧或时隙监听控制信道以接收基站发送的无线信号。其中，接收单元201接收到的信号可以是以OFDM波形承载的无线信号，即OFDM时域信号。

当CRC校验单元208不能解出DCI时，则由盲检单元205尝试下一次盲检。如果所有的盲检都无法成功，则丢弃该接收到的子帧或时隙。
当CRC校验单元208成功解出DCI时，获取单元209根据解出的DCI，获取DCI中的分配的资源的信息。具体的，获取单元209获取分配的资源的信息，可以参考上述图2、图4和图7描述的实现方式中终端设备接收到的分配的资源的信息的方式来实现。
例如，当获取单元209获取到的DCI采用的是上述图2、图3(a)和图3(b)描述的 实现方式中表示资源分配方式时，获取单元209根据DCI中的资源分配头字段获终端设备本次被分配的频域资源的标识；根据数据信道开始的符号字段获取终端设备本次被分配的时频资源开始的符号的信息；根据数据信道所占据的符号长度字段获取终端设备本次被分配的时频资源符号的长度信息。
当获取单元209获取到的DCI采用的是上述图4、图5、图6(a)、图6(b)和图6(c)中资源分配方式时，获取单元209根据DCI中的资源分配头字段获取终端设备本次被分配的时频资源的标识；根据偏移量字段获取终端设备本次被分配的时频资源相对于已经获取的有效时频资源的偏移量。
当获取单元209获取到的DCI采用的是上述图7和图8中资源分配方式时，获取单元209根据DCI中的资源分配头字段获取终端设备本次被分配的时频资源的标识，即可获取本次被分配的频域资源与上一个时频资源相同。
上述通信设备200接收到的DCI中，用于表示分配的时频资源的信息的字段所占用的比特位少，减少了DCI中资源分配相关字段所占用的时频资源。
进一步的，终端设备可以根据DCI中指示的资源分配的信息从数据信道占用的时频资源处获取基站发送的数据。终端设备从获取到的DCI中获取基站发送的数据的实现方式可以如下述方式实现：

解速率匹配单元206，还用于按照已经获取的DCI中的信息，对解扰单元204解扰后的比特序列进行解速率匹配。即通信设备200获取到的DCI中还包括对比特序列进行速率匹配的信息，解速率匹配单元206根据该速率匹配信息对解扰单元204解扰后的比特序列进行解速率匹配。
信道解码单元207，还用于按照已经获取的DCI中的信息，对解速率匹配单元206匹配后的比特序列进行信道解码，以获取数据。可选的，信道解码单元207获取到的数据是带有CRC校验信息的数据。即通信设备200获取到的DCI中还包括编码方式的信息，信道解码单元207根据该编码方式逆向的方式对解速率匹配单元206匹配后的比特序列进行信道解码。
