在当前的长期演进(Long Term Evolution,LTE)技术的讨论过程中,对于随机接入过程中的第三条消息即Msg3,可以在Msg3中传输上行用户数据,涉及利用媒体接入控制协议(Medium Access Control,MAC)随机接入响应(Random Access Responses,RAR)。
终端设备的覆盖增强模式可以包括:覆盖增强模式A(CE mode A)和覆盖增强模式B(CE mode B),其中,覆盖增强模式A用于较小覆盖增强程度,覆盖增强模式B用于较大覆盖增强程度。
如何实现在覆盖增强模式下的资源分配,以提升资源利用率,是本领域中亟需解决的问题。
发明内容
本申请实施例提供了一种信息传输的方法和设备,能够实现在覆盖增强模式下的资源分配,提升资源利用率。
第一方面,本申请实施例提供一种信息传输的方法,包括:
终端设备接收网络设备发送的下行控制信息,其中所述下行控制信息包含资源分配字段,所述资源分配字段用于指示所述分配的资源块或子载波资源,所述资源分配字段包括高
个比特和低M个比特,所述M是正整数,所述
表示上行带宽中包含的资源块的个数;
所述资源分配字段用于指示所述分配的资源块时,所述高
个比特指示窄带索引,所述低M个比特的比特状态中有L种比特状态能够用于指示窄带内的资源块分配,且所述L种比特状态中的每一种比特状态所指示的资源块的个数大于或等于1,所述资源分配字段使用所述L种比特状态中的一种比特状态指示所述分配的资源块,所述L是正整数;或,
所述资源分配字段用于指示所述分配的子载波资源时,所述M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,且所述K种比特状态中的每一种比特状态所指示的子载波的个数小于12,所述资源分配字段使用所述K种比特状态中的一种比特状态指示所述分配的子载波资源;其中,所述K是正整数;
所述终端设备根据所述资源分配字段确定分配的是资源块或者子载波资源,并在所述分配的资源块或者子载波资源上发送信息。
在本申请实施例中,网络设备通过资源分配字段包括的比特状态的取值不同来指示为终端设备分配资源块或者子载波资源,资源分配字段用于指示所述分配的资源块时,高
个比特指示窄带索引,低M个比特的比特状态中有L种比特状态能够用于指示窄带内的资源块分配,且L种比特状态中的每一种比特状态所指示的资源块的个数大于或等于1;或,资源分配字段用于指示所述分配的子载波资源时,M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,且K种比特状态中的每一种比特状态所指示的子载波的个数小于12数。从而实现能支持分配小于12个子载波的资源,可以将有效的资源分配给更多的UE,提高了频谱利用效率。
在第一方面一种可能的设计中,所述资源分配字段用于指示所述分配的子载波资源时,
所述M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,包括:
所述K种比特状态能够用于指示所述窄带内的X个资源块中的任一个资源块内的3个子载波或6个子载波的资源分配,且所述K种比特状态中的每种比特状态对应W种资源单元个数中的一个资源单元个数,所述X是正整数,所述W是正整数;
或,
所述方法进一步包括:所述终端设备接收无线资源控制信令或媒体接入控制信令,所述无线资源控制信令或媒体接入控制信令配置了T个资源块,所述T为正整数;
所述M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,包括:
所述K种比特状态能够用于指示所述T个资源块中的任一个资源块内的3个子载波或6个子载波的资源分配,且所述K种比特状态中的每种比特状态对应W种资源单元个数中的一个资源单元个数,所述W是正整数;
或,
所述方法进一步包括:所述终端设备接收无线资源控制信令或媒体接入控制信令,所述无线资源控制信令或媒体接入控制信令配置了N个资源块,N为正整数;
所述M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,包括:
所述K种比特状态能够用于指示所述N个资源块中的任一个资源块内的2个子载波、3个子载波或6个子载波的资源分配,且所述K种比特状态中的每种比特状态对应W种资源单元个数中一个资源单元个数,所述W是正整数;
或,
所述方法进一步包括:所述终端设备接收无线资源控制信令或媒体接入控制信令,所述无线资源控制信令或媒体接入控制信令配置了Y个资源块,所述Y是正整数;
所述M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,包括:
所述K种比特状态能够用于指示所述Y个资源块中的任一个资源块内的2个子载波、3个子载波或6个子载波的资源分配。
举例说明如下,K种比特状态能够用于指示窄带内的X个资源块中的任一个资源块内的3个子载波或6个子载波的资源分配,且K种比特状态中的每种比特状态对应W种资源单元个数中的一个资源单元个数,X是正整数,W是正整数。资源单元(Resource Unit,RU)在频域上占用的子载波个数小于12,时域上占用的资源大于一个子帧。如分配的子载 波是6个子载波时,资源单元频域上对应6个子载波的频率资源,时域上占据2个子帧。如分配的子载波是3个子载波时,资源单元频域上对应3个子载波的频率资源,时域上占据4个子帧。如分配的子载波是2个子载波时,资源单元频域上对应2个子载波的频率资源,时域上占据8个子帧。资源分配的粒度为3个子载波或者6个子载波。
举例说明,网络设备可以发送无线资源控制信令或者媒体接入控制信令,具体使用哪种信令取决于应用场景。在无线资源控制信令或媒体接入控制信令配置了T个资源块,资源分配的粒度为3个子载波或者6个子载波。
在第一方面一种可能的设计中,
所述终端设备处于覆盖增强等级0、覆盖增强等级1、或覆盖增强模式A;
所述M=7,所述L=21,所述K=107,所述W=3,所述X=6;或,
所述M=7,所述L=21,所述K=105,所述W=3,所述X=6;或,
所述M=7,所述L=20,所述K=108,所述W=3,所述X=6;或,
所述M=7,所述L=20,所述K=106,所述W=3,所述X=6;或,
所述M=7,所述L=20,所述K=96,所述W=4,所述X=4;或,
所述M=7,所述L=21,所述K=107,所述W=3,所述T=6;或,
所述M=7,所述L=21,所述K=105,所述W=3,所述T=6;或,
所述M=7,所述L=20,所述K=108,所述W=3,所述T=6;或,
所述M=7,所述L=20,所述K=106,所述W=3,所述T=6;或,
所述M=7,所述L=20,所述K=96,所述W=4,所述T=4;或,
所述M=7,所述L=21,所述K=90,所述W=3,所述N=3;
所述M=6,所述L=21,所述K=40,所述Y=4。
如M=7,L=21,K=107,W=3,X=6时,7比特共有128种状态。假设有3种RU个数,RU个数分别是1个RU,2个RU,4个RU。128种状态中有21种状态指示窄带内的资源块分配。子载波资源分配时,在6个资源块中的每个资源块内进行3个子载波和6个子载波的分配,而且每种子载波的分配都对应3种RU的分配。这样结合上表,总共需要3(3种RU个数)*6(6个资源块)*6(每个资源块内有6中子载波分配)=108种状态指示子载波和RU的分配。但7个比特中还有107中状态可用,因此从上述108种状态中去掉一种指示子载波和RU的分配组合。如资源分配不支持在窄带内的第6个RB上4RU和6个子载波的分配。
进一步地,考虑到提前数据终止和/或控制信道终止还需要1或2种状态。可以在107种状态中进一步预留出1或2种状态指示提前数据终止和/或控制信道终止。这样,可以用106或105种状态指示子载波和RU的分配。去掉的子载波和RU的分配组合是标准预先规定的。
可选地,去掉一种资源块分配的组合,即128种状态中有20种状态指示窄带内的资源块分配。这样用3(3种RU个数)*6(6个资源块)*6(每个资源块内有6中子载波分配)=108种状态指示子载波和RU的分配。
在第一方面一种可能的设计中,
所述终端设备处于覆盖增强等级2、覆盖增强等级3、或覆盖增强模式B;
所述M=5,所述L=8,所述K=24,所述W=2,所述X=2;或,
所述M=5,所述L=8,所述K=24,所述W=4,所述X=1;或,
所述M=5,所述L=8,所述K=18,所述W=3,所述X=1;或,
所述M=7,所述L=8,所述K=120,所述W=4,所述X=5;或,
所述M=5,所述L=8,所述K=24,所述W=2,所述T=2;或,
所述M=5,所述L=8,所述K=24,所述W=4,所述T=1;或,
所述M=5,所述L=8,所述K=18,所述W=3,所述T=1;或,
所述M=7,所述L=8,所述K=120,所述W=4,所述T=5;或,
所述M=5,所述L=8,所述K=20,所述W=2,所述N=1;或,
所述M=7,所述L=8,所述K=120,所述W=3,所述N=4;或,
所述M=7,所述L=8,所述K=120,所述W=4,所述N=3;或,
所述M=7,所述L=8,所述K=120,所述W=2,所述N=6;或,
所述M=5,所述L=8,所述K=20,所述Y=2。
如M=5,L=8,K=24,W=2,X=2时,5比特共有32种状态。假设有2种RU个数,RU个数分别是2个RU,4个RU。32种状态中有8种状态指示窄带内的资源块分配。子载波资源分配时,在2个资源块中的每个资源块内进行3个子载波和6个子载波的分配,而且每种子载波的分配都对应2种RU的分配。这样结合上表,总共需要2(2种RU个数)*2(2个资源块)*6(每个资源块内有6种子载波分配)=24种状态指示子载波和RU的分配。
这里M,L,K,W,X,T,N,Y的组合按照上述说明类似地进行资源块和子载波资源的分配,这里不再赘述。

请参阅图2所示,为本申请实施例提供的网络设备和终端设备之间的一种交互流程示意图,本申请实施例提供的信息传输的方法,主要包括如下步骤。
201、网络设备为终端设备分配资源块或者子载波资源。
在本申请实施例中,网络设备为终端设备进行资源分配时可以分配资源块,即以最小单位为1个资源块进行资源分配,网络设备还可以为终端设备分配子载波资源,即以子载波为单位进行资源分配。例如网络设备可以根据当前网络负载确定以资源块或者子载波资源为单位进行资源分配。举例说明,在本发明实施例中,网络设备使用下行控制信息(Downlink Control Information,DCI)格式6-0A对物理上行共享信道(Physical Uplink Shared channel,PUSCH)进行资源分配时,最小单位可以是1个资源块,并且也能够支持分配小于12个子载波的资源,因此提高了PUSCH的频谱效率。
202、网络设备确定下行控制信息(Downlink Control Information,DCI),其中下行控制信息包含资源分配字段,所述资源分配字段用于指示所述分配的资源块或子载波资源,资源分配字段包括高
个比特和低M个比特,M是正整数,
表示上行带宽中包含的资源块的个数;
资源分配字段用于指示所述分配的资源块时,高
个比特指示窄带索引,低M个比特的比特状态中有L种比特状态能够用于指示按照上行资源分配类型0进行窄带内的资源块分配,且L种比特状态中的每一种比特状态所指示的资源块的个数大于或等于1,所述资源分配字段使用所述L种比特状态中的一种比特状态指示所述分配的资源块,L是正整数;或,
资源分配字段用于指示所述分配的子载波资源时,M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,且K种比特状态中的每一种比特状态所指示的子载波的个数小于12,所述资源分配字段使用所述K种比特状态中的一种比特状态指示所述分配的子载波资源;其中,K是正整数。
具体的,
表示系统带宽中包含的上行物理资源块(physical resource block,PRB)的个数,
表示向下取整运算,
表示向上取整运算。当资源分配字段用于指示所述分配的资源块时,资源分配字段也可以包括的高比特是
和低M个比特,则高比特
指示窄带索引,低M个比特的比特状态中有L种比特状态能够用于指示窄带内的资源块分配,且L种比特状态中的每一种比特状态所指示的资源块的个数大于或等于1,L是正整数。如,M的取值可以为7,L的取值为21。或者,M=5,L=8。资源分配字段所指示的资源块的数目大于或等于1,即资源分配的粒度为PRB级。
资源分配字段用于指示所述分配的子载波资源时,资源分配字段包含高
个比特和低M比特,高
个比特指示窄带索引,低M比特指示K个资源块内的子载波资源的分配,且资源分配字段所指示子载波个数小于12。通常情况下,1个资源块包括12个子载波,本申请实施例中资源分配字段所指示子载波个数小于12,即资源分配的粒度为子PRB级(sub PRB)或子载波,因此可以具有更小的资源分配粒度。低M比特指示K个资源块内的子载波资源的分配,此时的K个资源块为网络设备配置的资源块,或者预设的资源块。这样,可以通过低M个比特,网络设备可以向终端设备指示所分配的子载波资源。203、网络设备向终端设备发送下行控制信息。
其中,网络设备确定下行控制信息之后,网络设备可以向终端设备发送下行控制信息,该下行控制信息包含资源分配字段,资源分配字段指示了分配给终端设备的资源块或者子载波资源。
资源分配字段用于指示所述分配的资源块时,高
个比特指示窄带索引,低M个比特的比特状态中有L种比特状态能够用于指示窄带内的资源块分配,且L种比特状态中的每一种比特状态所指示的资源块的个数大于或等于1,L是正整数;或,
资源分配字段用于指示所述分配的子载波资源时,M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,且K种比特状态中的每一种比特状态所指示的子载波的个数小于12;其中,K是正整数。
205、终端设备根据资源分配字段确定分配的是资源块或者子载波资源。
206、终端设备在分配的资源块或者子载波资源上发送信息。
在本发明实施例中,终端设备通过资源分配字段可以确定网络设备以资源块为单位进行资源分配,或者以子载波资源为单位进行资源分配,并通过资源分配字段包括的高比特的状态和低比特的状态确定出分配给的资源,终端设备可以网络设备分配的资源完成上行信息的发送。
207、网络设备在下行控制信息确定的资源上接收终端设备发送的信息。
在本申请实施例中,网络设备在分配给终端设备的资源检测终端设备发送的信息,终端设备发送的信息可以使用网络设备分配的资源块或者子载波资源,具体取决于网络设备对资源的配置情况。
通过前述实施例对本申请的举例说明可知,网络设备通过资源分配字段包括的比特状态的取值不同来指示为终端设备分配资源块或者子载波资源,资源分配字段用于指示所述分配的资源块时,高
个比特指示窄带索引,低M个比特的比特状态中有L种比特状态能够用于指示窄带内的资源块分配,且L种比特状态中的每一种比特状态所指示的资源块的个数大于或等于1;或,资源分配字段用于指示所述分配的子载波资源时,M个比特的比特状态中有K种比特状态能够用于指示子载波资源的分配,且K种比特状态中的每一种比特状态所指示的子载波的个数小于12数。从而实现能支持分配小于12个子载波的资源,可以将有效的资源分配给更多的UE,提高了频谱利用效率。

如M=7,L=21,K=107,W=3,X=6时,7比特共有128种状态。假设有3种RU个数,RU个数分别是1个RU,2个RU,4个RU。128种状态中有21种状态指示窄带内的资源块分配。子载波资源分配时,在6个资源块中的每个资源块内进行3个子载波和6个子载波的分配,而且每种子载波的分配都对应3种RU的分配。这样结合上表,总共需要3(3种RU个数)*6(6个资源块)*6(每个资源块内有6中子载波分配)=108种状态指示子载波和RU的分配。但7个比特中还有107中状态可用,因此从上述108种状态中去掉一种指示子载波和RU的分配组合。如资源分配不支持在窄带内的第6个RB上4RU和6个子载波的分配。
进一步地,考虑到提前数据终止和/或控制信道终止还需要1或2种状态。可以在107种状态中进一步预留出1或2种状态指示提前数据终止和/或控制信道终止。这样,可以用106或105种状态指示子载波和RU的分配。去掉的子载波和RU的分配组合是标准预先规定的。
可选地,去掉一种资源块分配的组合,即128种状态中有20种状态指示窄带内的资源块分配。这样用3(3种RU个数)*6(6个资源块)*6(每个资源块内有6中子载波分配)=108种状态指示子载波和RU的分配。

如M=6,L=21,K=40,Y=4时,6比特共有64种状态。此时资源分配不指示RU的分配。64种状态中有21种状态指示窄带内的资源块分配。子载波资源分配时,在4个资源块中 的每个资源块内进行2、3、6个子载波的分配。这样结合上表,总共需要4(4个资源块)*10(每个资源块内有10种子载波分配)=40种状态指示子载波和RU的分配。

本申请实施例中,可以实现DCI能够支持为PUSCH分配小于12个子载波的资源,设计DCI的比特,使得只用新增较少的DCI比特,就能够对分配的子载波和RU个数进行指示的问题。从而UE可以把发送功率集中到更小的带宽上,以提高PUSCH的频谱效率,并且节省了DCI的比特开销。
在本申请的一些实施例中,可以采用
比特指示任意的RB级资源分配和高层配置的或者预设的窄带内或者系统带宽内的2个RB内的sub-PRB资源分配,其中,
用于指示系统带宽内的窄带索引。比特指示的32种状态中的8个状态用于指示legacy的PRB粒度的资源分配;32种状态剩余的24种状态指示的资源分配包括下面的实施方式。

本申请实施例中,下行控制信息中资源分配字段采用联合编码,比独立编码节省1比特。在RU个数和资源分配单独编码中,RU个数:2种状态,需要1比特。资源分配:2x6+8=20中状态,需要5比特。本发明实施例中资源分配字段需要增加2比特,能同时支持现有RB级、3、6个子载波的资源分配和RU个数的指示。
7比特指示的32种状态中的8个状态用于指示PRB粒度的资源分配。
7比特指示的128种状态中剩余的120种状态指示的资源分配包括下面的实施方式:

302、终端设备根据资源分配字段确定分配的是资源块或者子载波资源,并在分配的资源块或者子载波资源上发送信息。
