本申请要求在2021年09月13日提交中华人民共和国国家知识产权局、申请号为202111070717.X、申请名称为“一种跳频图案指示方法及装置”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。
本申请涉及无线通信技术领域,尤其涉及一种跳频图案指示方法及装置。
随着物联网等应用的不断普及,网络中接入用户的数量将以几何级数增长。在频谱等通信资源有限的背景下,需要考虑非正交的多址接入方式,即多个用户在通信过程中共享相同的时、频、空域等资源。在非正交多址接入中,由于用户共享相同的通信资源,为了解决多用户间干扰问题,可以在通信系统中引入跳频机制,通过使用户在每次传输中随机选择不同的频带,来随机化用户间的干扰,进而改善在非正交多址接入中的多址干扰问题。
目前第三代移动通信伙伴项目(3rd generation partnership project,3GPP)协议中,在设计跳频图案时,在时域只有两个跳频时刻,频域则只存在两个频点。当网络中接入用户数较多时,每个频段上仍然具有大量的干扰用户,用户之间的干扰较大。
发明内容
本申请提供一种跳频图案指示方法及装置,用以减少用户之间的干扰。
第一方面,提供一种跳频图案指示方法。在该方法中,第一终端设备获取第一指示信息,第一指示信息用于指示跳频图案,第一终端设备基于跳频图案进行通信。
第一指示信息可以指示一个或多个跳频图案。在第一指示信息用于指示一个跳频图案时,第一终端设备基于该跳频图案进行通信。在第一指示信息用于指示多个跳频图案(例如包括第一跳频图案和第二跳频图案)时,第一终端设备在多个跳频图案中选择一个跳频图案(例如选择第一跳频图案或者选择第二跳频图案)进行通信。
其中第一终端设备可以从网络设备中获取第一指示信息,或者第一终端设备可以从第一终端设备自身获取第一指示信息。
跳频图案用于指示第一终端设备在跳频时刻进行通信时占用的频段。第一终端设备和任意其它终端设备在一个周期内至多在一个跳频时刻有碰撞,也就是说,在一个周期内第一终端设备和任意其它终端设备发生碰撞的次数最多为1。因此在该方法中通过跳频图案的指示和设计,可以使得用户之间的发生碰撞的次数尽可能少,从而减少用户之间的干扰。
两个终端设备之间有碰撞,指两个终端设备在同一个跳频时刻选择了相同的频段。
在该方法中,一个周期对应两个以上的跳频时刻和两个以上的频段。一个周期可以是指跳频序列的循环节的长度。一种可能的方式中,跳频序列的循环节的长度可以根据支持的最大跳频时刻数确定。另一种可能的方式中,跳频序列的循环节的长度可以根据支持的 频段的数量确定。
示例的,第一终端设备可以基于跳频图案,与网络设备进行通信。如果第一指示信息指示了多个跳频图案,网络设备可以在多个跳频图案对应的频段上尝试接收第一终端设备发送的信息。
在一种可能的设计中,第一终端设备和任意其它终端设备在一个周期内至多在一个跳频时刻有碰撞可以通过欧式空间的性质实现,其中欧式空间中的点与终端设备对应,例如在欧式空间中,每个跳频时刻与平行线簇对应,平行线簇包括多条相互平行的线段,每个频段与(一条或多条)线段对应,每条线段包括多个点,终端设备与(一个或多个)点对应。由于欧式空间中的任意两条线段只有相交或平行两种位置关系,相交的线段只有一个角点,因此可以使得任意两个终端设备在一个周期内发生碰撞的次数不超过1。

网络设备也可以包括核心网设备。示例的,核心网设备可以包括会话管理功能(session management function,SMF)等。
3)跳频图案,也称跳频序列,用于指示在跳频时刻的频段选择。如果多个设备(一般指多个终端设备)在同一跳频时刻选择了相同频段,则认为多个设备之间发生了碰撞。
4)欧式空间,可以是二维空间或更高维空间。
在本申请实施例中欧式空间中的点可以对网络中终端设备一一对应,在欧式空间中,任意两条线段只有相交或平行两种位置关系,相交的两条线段只有一个交点。因此利用欧式空间中的这个性质,对跳频图案进行设计,可以使得即任意两个终端设备的跳频图案的最大碰撞次数为1。
本申请中的“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本申请中所涉及的至少一个是指一个或多个,多个是指两个或两个以上。
另外,需要理解的是,在本申请的描述中,“第一”、“第二”等词汇,仅用于区分描述的目的,而不能理解为指示或暗示相对重要性,也不能理解为指示或暗示顺序。
本申请实施例的技术方案可以应用于各种通信系统(也称移动通信系统或无线通信系统)。如图1所示为一种可能的通信系统架构,包括一个或多个网络设备(如图1中的基站),和一个或多个终端设备(如图1中的UE1~UE6)。基站可以向UE1~UE6发送数据,UE1~UE6也可以将上行数据发送给基站。可选的,UE4、UE5和UE6可以组成一个通信系统。在该通信系统中,基站可以发送下行数据给UE1、UE2和UE5等,UE5可以将下行数据转发给UE4和UE6。例如UE5可以作为中继节点,对UE和基站之间的数据进行转发。例如中继节点可以部署在单跳(Single-hop)或多跳(Multi-hop)中继系统,中继节点的形态可以为客户终端设备(customer-premises equipment,CPE)、小站、接入回传一体化(integrated access and backhaul,IAB)节点、DU、终端设备、TRP等。
在无线通信系统中,多用户在时、频、空域等资源上的复用是一个需要着重考虑的问题。现有的LTE、NR等系统采用正交多址接入的方式来对用户进行时、频、空域等资源的分配,使得每个用户可以独占某一频域、时域或空域资源。随着物联网等应用的不断普及,无线网络中接入用户的数量将以几何级数增长。在频谱等通信资源有限的背景下,需要考虑非正交的多址接入方式,即多个用户在通信过程中共享相同的时、频、空域等资源。在非正交多址接入中,由于用户共享相同的通信资源,为了解决多用户间干扰(即多址干扰)问题,可以在通信系统中引入跳频机制,通过使用户在每次传输中随机选择不同的频带,来随机化用户间的干扰,进而改善在非正交多址接入中的多址干扰问题。
目前3GPP协议中规定了一种跳频图案的设计方案,支持时隙内跳频(Intra-slot frequency hopping)和跨时隙跳频(Inter-slot frequency hopping)。时隙内跳频应用于单时隙或多时隙的物理上行共享信道(physical uplink shared channel,PUSCH)传输场景,跨时 隙跳频应用于多时隙的PUSCH传输场景。
对于时隙内跳频,每次跳频的起始资源块(resource block,RB)位置可以通过下述公式(1)计算得到。
其中i=0表示跳频时刻0,i=1表示跳频时刻1,RB
start表示上行带宽部分(bandwidth part,BWP)的起始RB位置,可以通过资源分配类型1的资源块配置信息来确定,RB
offset表示两次跳频间的频域偏移,
表示通信带宽部分所占的频带大小。
上述跳频图案的设计较为简单,在时域只有两个跳频时刻,频域只存在两个频段。当网络中接入的用户数量较多时,每个频段上仍具有大量的干扰用户,用户之间的干扰较大。
基于此,本申请实施例提供了一种跳频图案指示方法,可以应用于图1所示的通信系统中,可以应用于通信系统下的单用户或多用户数据传输场景。在该方法中,网络设备可以向第一终端设备指示跳频图案,第一终端设备基于该跳频图案进行通信,跳频图案用于指示第一终端设备在跳频时刻进行通信时占用的频段,其中第一终端设备和任意其它终端设备在一个周期内至多在一个跳频时刻有碰撞,第一周期对应两个以上的跳频时刻和两个以上的频段,因此可以减少用户之间的干扰。其中碰撞指两个终端设备在同一跳频时刻选择了相同的频段,发生碰撞的两个终端设备之间可能互相干扰,因此本申请实施例中通过降低终端设备之间的碰撞次数,可以减少终端设备(即用户)之间的干扰。
图2为本申请实施例提供的一种可能的跳频图案指示方法,包括以下步骤:
S201:第一终端设备获取第一指示信息。
在一个示例中,第一终端设备可以从网络设备中获取第一指示信息,即网络设备可以发送该第一指示信息。
可选的,第一指示信息包括跳频图案的标识信息,此时终端设备保存有跳频图案的标识信息与跳频图案的对应关系;或者第一指示信息可以包括跳频图案,即第一指示信息可以指示跳频图案本身,此时终端设备可以保存跳频图案或者也可以未保存有跳频图案。
跳频图案的标识信息可以包括跳频图案在跳频图案集合中的标号,或者可以包括签名序列,签名序列的频带粒度可以是资源块级别或资源单元级别。关于跳频图标的标识信息在下文进行描述。
该示例可以应用于如下场景:
场景1:基于调度(scheduled)的上行数据传输场景。网络设备向第一终端设备发送第一指示信息,第一终端设备根据网络设备的调度进行激活并发送数据。
若网络中接入多个终端设备(包括第一终端设备),网络设备可以分别向每个终端设备发送对应的指示信息来指示跳频图案。
场景2:基于预配置(configured)的上行数据传输场景。网络设备向第一终端设备发送第一指示信息,第一终端设备在数据到达时进行随机激活并发送数据。
场景3:基于随机选择(random selection)的上行数据传输场景,网络设备向第一终 端设备广播多个跳频图案,第一终端设备在数据到达时进行随机激活,并且在多个跳频图案中随机选择一个跳频图案发送数据。
在该场景下,第一指示信息可以指示一个或多个跳频图案的标识信息,终端设备选取一个标识信息对应的跳频图案。该一个或多个跳频图案可以属于一个跳频图案集合。
在另一个示例中,第一终端设备中可以预先配置或协议规定有第一指示信息,第一终端设备可以从第一终端设备自身获取第一指示信息。
第一指示信息用于指示跳频图案,跳频图案可以理解为跳频序列,用于指示第一终端设备在跳频时刻进行通信时占用的频段。跳频图案指示的频段(即跳频图案在频域上的频段)可以是连续的频段,或者是不连续的频段,一个频段可以包括一个或多个频点。频点可以为资源块RB级别或资源单元(resource element,RE)级别。跳频图案在时域上的粒度可以为一个或多个正交频分复用(orthogonal frequency-division multiplexing,OFDM)符号,或者可以为一个或多个时隙。
其中第一终端设备和任意其它终端设备在一个周期内至多在一个时刻有碰撞,一个周期对应两个以上的跳频时刻和两个以上的频段。具体而言,在欧式空间中,每个跳频时刻与(一个或多个)平行线簇对应,每个频段与(一个或多个)线段对应,一个平行线簇包括多条相互平行的线段,每条线段包括多个点,(一个或多个)终端设备与欧式空间中的点对应。
两个终端设备有碰撞指两个终端设备在同一跳频时刻选择了相同的频带,本申请实施例通过跳频图案的设计可以使得不同终端设备之间的最大碰撞次数可以灵活配置,由于一个周期内终端设备之间的最大碰撞次数为1,例如一种方式中,可以将多个周期进行拼接组合,来灵活配置终端设备之间的最大碰撞次数。并且对于频率选择性衰落信道,跳频图案可以尽可能的利用频域分集,来进一步有效提升通信系统的可靠性。
一个周期可以是指跳频序列的循环节的长度。一种可能的方式中,跳频序列的循环节的长度可以根据支持的最大跳频时刻数确定,支持最大的跳频时刻数量可以通过根据跳频时刻集合中元素表示,例如支持的最大跳频时刻数为5,一个跳频时刻集合可以包括T1、T2、T3、T4、T5共5个元素,此时一个周期内可以包括5个跳频时刻,分别为T1、T2、T3、T4、T5,并且每个跳频时刻对应有频段(一般对应一个频段)。另一种可能的方式中,跳频序列的循环节的长度可以根据支持的频段的数量确定,支持的频段的数量可以通过频段集合中元素的数量表示,例如支持4个频段,一个频段集合可以包括F1、F2、F3和F4共4个元素,此时一个周期内可以包括4个频段,并且每个频段对应跳频时刻(一般可以对多个跳频时刻)。可以理解,本申请中对支持的最大跳频时刻数和频段数不做限制。
S202:第一终端设备基于第一指示信息指示的跳频图案进行通信。
对应的,网络设备可以基于第一指示信息指示的跳频图案进行通信。
例如,在第一跳频时刻时,网络设备和终端设备采用跳频图案中第一跳频时刻对应的第一频段进行通信。
网络设备和终端设备中保存有跳频图案或跳频图案集合(包括一个或多个跳频图案)。跳频图案或跳频图案集合可以由3GPP协议规定,或者可以由网络设备生成,或者可以由终端设备生成,本申请实施例以跳频图案集合为例进行说明。网络设备或终端设备生成跳频图案集合,可以减少网络设备和终端设备的存储开销,并且跳频图案具有伪随机特性。
方式1:跳频图案由网络设备生成。
网络设备获取第一参数和第二参数,网络设备可以根据第一参数和第二参数,生成跳频图案集合,跳频图案集合包括一个或多个跳频图案,该一个或多个跳频图案包括上述第一指示信息指示的跳频图案。
可选的,网络设备可以将生成的跳频图案集合发送给终端设备。
一种可能的实现中,第一参数与欧式空间维数相关。第二参数与欧式空间中的点相关,欧式空间中的点与终端设备对应。示例的,欧式空间中的点可以与网络中的终端设备一一对应。
网络设备在获取第一参数和第二参数时,可以根据频段数量、网络中终端设备的数量以及跳频时刻的数量,确定第一参数和第二参数。其中在m维欧式空间中,欧式空间中的点构成m维向量a=[a
1a
2…a
m],其中向量中的元素a
i∈GF(2
s),i∈[1,m],GF为伽罗华域(galois field),因此可以将m维欧式空间记为EG(m,2
s),即m维欧式空间中包含2
ms个点,即支持2
ms个用户。令a
0与a为两个线性独立的点(即β
0a
0+βa≠0,除非β
0=β=0),则存在如下2
s个点的集合{a
0+βa}。其中β∈GF(2
s),构成EG(m,2
s)中一条过点a
0的线段。由于欧式空间中共有2
ms个点,而一条线段由2
s个点构成。因此一个平行线簇内可以包含2
(m-1)s条相互平行的平行线段,即在一个跳频时刻内可选的频段数量q=2
(m-1)s。此外,EG(m,2
s)中包含的平行线簇一共有(2
ms-1)/(2
s-1)个,因此可以支持的最大跳频时刻等于(2
ms-1)/(2
s-1)。因此网络设备可以根据频段数量q=2
(m-1)s,网络中终端设备的数量K=2
ms以及跳频时刻的数量T
max=(2
ms-1)/(2
s-1),选择合适的第一参数m和第二参数s。
网络设备在根据第一参数和第二参数,生成跳频图案集合时,包括以下步骤:
网络设备确定第一参数和第二参数对应的本原多项式,其中本原多项式用于生成第一表示形式和第二表示形式,具体而言,本原多项式用于生成每个点的第一表示形式和第二表示形式。例如下述表1.1示出了16个点对应的幂表示形式、多项式表示形式和二进制表示形式,其中第一表示形式和第二表示形式为幂表示形式、多项式表示形式和二进制表示形式中的两种,例如第一表示形式为幂表示形式,第二表示形式为二进制表示形式。可以理解,本申请实施例的表1.1仅为一种示例,而不对表示形式构成限定,表1.1中的表示形式可以更多或更少,例如可以对表1.1中各表示形式进行拆分或合并等。
表1.1

a 11 | a+a 2+a 3 | (0111) |
a 12 | 1+a+a 2+a 3 | (1111) |
a 13 | 1+a 2+a 3 | (1011) |
a 14 | 1+a 3 | (1001) |
网络设备根据第一表示形式,确定每个跳频图案中对应第二跳频时刻的第一平行线簇中通过原点的第一线段,其中第一线段上的点表示第一线段对应频段上的终端设备。例如原点的坐标为0,对于第二跳频时刻t的平行线簇t∈[1,T],网络设备确定非原点的初始点p
t=α
t,通过下述公式(3)计算平行线簇t内通过原点的第一线段l
0,以及第一线段l
0上所包含的2
s个点。
k·p
t(3)
网络设备根据第一表示形式和第二表示形式和每个跳频图案中的第一线段,确定每个第一平行线簇中所有平行于第一线段的第二线段。例如对于第二跳频时刻t的平行线簇t∈[1,T],网络设备可以通过下述公式(4)计算平行与第一线段l
0的剩余2
(m-1)s-1条第二线段,以及每条第二线段上所包含的点。
p
0+k·p
t(4)。其中p
0≠0并且与p
t线性独立。
可以理解,在该方式中,主要基于GF(2
s)的生成跳频图案,对于其余素数幂的伽罗华域(即GF(p
s),其中p是一个素数)的生成流程类似。
网络设备根据每个第一平行线簇中的第一线段与第二线段和点的映射关系,确定跳频图案集合中的每个跳频图案。
网络设备在根据第一参数和第二参数,生成跳频图案集合时,包括以下步骤:
网络设备确定第一参数和第二参数对应的本原多项式f(X)=f

ms+…+f
1X+f
0,其中f
l∈[0,1],l=0,1,…,ms,如表1.2所示,其中d表示本原多项式f(X)中X的最大次幂。例如,当m=2,s=2时对应的本原多项式为f(X)=X
4+X+1。

本原多项式 | |
d=3 | f(X)=X 3+X+1 |
d=4 | f(X)=X 4+X+1 |
d=5 | f(X)=X 5+X 2+1 |
d=6 | f(X)=X 6+X+1 |
d=7 | f(X)=X 7+X 3+1 |
d=8 | f(X)=X 8+X 4+X 3+X 2+1 |
本原多项式用于生成GF(2
ms)中每个点第一表示形式和第二表示形式的映射关系,其中第一表示形式为幂表示形式,第二表示形式为二进制向量。例如,表1.3示出了16个用户点对应的幂表示形式和二进制向量表示形式,其中用户ID1~16分别表示16个用户点。
表1.3
用户ID | 幂表示 | 4维向量的二进制表示 |
1 | 0 | (0000) |
2 | 1 | (1000) |

14 | a 12 | (1111) |
15 | a 13 | (1011) |
16 | a 14 | (1001) |
根据本原多项式生成GF(2
ms)中K=2
ms个点的二进制表示形式可以基于如下流程:
根据第一参数和第二参数确定本原多项式f(X)=f
msX
ms+…+f
1X+f

ms-1]为本原多项式中除最高次项以外其余项的系数所构成的二进制向量。对于GF(2
ms)中的点“0”与点“1”(幂表示形式),令其对应的二进制向量分别为b
1=[0 0…0]
ms×1以及b
2=[1 0…0]
ms×1。例如,当m=2,s=2时,有b
1=[0 0 0 0]
4×1以及b
2=[1 0 0 0]
4×1。对于剩余点的二进制表示,可以通过如下操作计算得出,b
i=circshift(b
i-1,1),i=3,4,…,2
ms,其中circshift(v,1)表示对向量v向右循环移位一位。循环移位完成后,当b
i(1)=1时,令b
i(1)=0,并且b
i=mod(b
i+b
primpoly,2),从而得到最终的二进制表示形式。
令最大跳频时刻数T
max=(2
ms-1)/(2
s-1),可以通过如下两步计算在[1,T
max]个跳频时刻内分别映射至R个频段上的用户集合:
第一步:确定在时刻t∈[1,T
max],映射到频段r=1上的2
s个用户集合U
r=1,t。首先,令U
r=1,t(1)=1,即用户1在时刻t映射到频段r=1。计算E
r=1,t=mod(k+u
t,K-1),其中u
t=u(t)为向量u=[2,3,…,T
max+1]中的第t个元素,向量k=T
max·[0,1,…,2

s-1个用户的ID为U
r=1,t(i)=E
r=1,t(i-1)+2,i=2,3,…,2
s。
第二步:确定在时刻t∈[1,T
max],映射到频段其余频段上用户的集合U
r,t,r≠1。 对于任意频段r>1,令
其中U=[1,2,…,K]为全体用户ID集合,即

r,t以外的最小用户ID。从表1.3中查找用户
对应的二进制向量表示形式
并且计算
其中B
r=1,t对应于映射到频段r=1上的2
s个用户的二进制向量表示形式。根据计算得出的二进制向量表示B
r,t,从表1.3中查找对应的用户ID,即为在时刻t映射到频段r上的2
s个用户集合U
r,t。
方式2:跳频图案由终端设备生成。
在该方式2中,网络设备可以向终端设备发送第二指示信息,第二指示信息用于指示生成跳频图案集合的参数。例如第二指示信息包括以下一种或多种:第一参数m、第二参数s、本原多项式P(X),跳频时刻集合
网络中终端设备与欧式空间中点的对应关系(即终端设备在欧式空间中对应点的标号)。其中跳频时刻的排序,可以对应平行线簇的任意排序,这里不做限制,例如可以由网络设备指示给终端设备。
在该方式中终端设备生成跳频图案的过程可以参见上述方式1中网络设备生成跳频图案的过程,相似之处不做赘述。
可选的,终端设备可以将生成的跳频图案集合发送给网络设备。
方式3:跳频图案由3GPP协议规定。
以终端设备的数量为16,跳频时刻为5为例,生成的平行线簇如图3所示。欧式空间中16个点分别对应16个UE,每个平行线簇内4个相互平行的线段分别对应频段F1~F4,F1上的UE采用白色填充的圆形表示,F2上的UE采用黑色填充的圆形表示,F3上的UE采用斜线填充的圆形表示,F4上的UE采用网格填充的圆形表示。将每个平行线簇作为一个跳频时刻,UE可以根据其在欧式空间中对应点的标号,在一个跳频时刻选择对应的频段进行通信。
如图3中的(a)所示,在平行线簇1对应的第一跳频时刻T1,选择频段F1的UE包括UE1、UE5、UE9和UE13,选择频段F2的UE包括UE2、UE6、UE10和UE14,选择频段F3的UE包括UE3、UE7、UE11和UE15,选择频段F4的UE包括UE4、UE8、UE12和UE16。如图3中的(b)所示,在平行线簇2对应的第一跳频时刻T2,选择频段F1的UE包括UE1、UE2、UE3和UE4,选择频段F2的UE包括UE5、UE6、UE7和UE8,选择频段F3的UE包括UE9、UE10、UE11和UE12,选择频段F4的UE包括UE13、UE14、UE15和UE16。如图3中的(c)所示,在平行线簇3对应的第一跳频时刻T3,选择频段F1的UE包括UE1、UE6、UE11和UE16,选择频段F2的UE包括UE2、UE7、UE12和UE13,选择频段F3的UE包括UE3、UE8、UE9和UE14,选择频段F4的UE包括UE4、UE5、UE10和UE15。如图3中的(d)所示,在平行线簇4对应的第一跳频时刻T4,选择频段F1的UE包括UE1、UE7、UE9和UE15,选择频段F2的UE包括UE2、UE8、UE10和UE16,选择频段F3的UE包括UE3、UE5、UE11和UE13,选择频段F4的UE包括UE4、UE6、UE12和UE14。如图3中的(e)所示,在平行线簇5对应的第一跳频时刻T5,选择频段F1的UE包括UE4、UE7、UE10和UE13,选择频段F2的UE包括UE3、UE6、UE9和UE16,选择频段F3的UE包括UE2、UE5、UE12和UE15,选择频段F4的UE包括UE1、UE8、UE11和UE14。
可以理解,在每个平行线簇内,线段与频段的对应关系不唯一。例如,除了图3中给出的映射方式外,一种可能的方式是包括白色填充的圆形的线段对应F2,包括斜线填充的 圆形的线段对应F1,包括网格填充的圆形的线段对应F3,包括黑色填充的圆形的线段对应F4。此外,不同平行线簇可以采用不同的映射方式,在本申请实施例中不做限定。
根据图3可以得到,每个UE在不同跳频时刻选择的频段,例如UE2在跳频时刻T1~T5的频段分别为F2、F1、F2、F2和F3。
基于图3,表2给出了欧式空间中16个UE对应的跳频图案,其中表中第一行表示跳频时刻,其余每行表示一个跳频图案,表2中第一列表示UE的标号,第二列到第六列对应不同跳频时刻下的频段。可以理解,本申请实施例的表2仅为一种示例,而不对用户(或终端设备)、跳频时刻和频段构成限定,表2中的用户(或终端设备)、跳频时刻和频段可以更多或更少。

可选的,在一些情况下,表2中第一列可以替换为跳频图案的标号,如表3所示。表3给出了欧式空间中16个跳频图案,其中表中第一行表示跳频时刻,其余每行表示一个跳频图案,表3中第一列表示跳频图案的标号,第二列到第六列对应不同跳频时刻下的频段。可以理解,本申请实施例的表3仅为一种示例,而不对跳频图案的标号、跳频时刻和频段构成限定,表3中的跳频图案的标号、跳频时刻和频段可以更多或更少。

15 | F3 | F4 | F4 | F1 | F3 |
16 | F4 | F4 | F1 | F2 | F2 |
由于在欧式空间,任意两条线段只有相交或平行两种位置关系,相交的两条线段只有一个交点,因此可以使得任意两个跳频图案在一个周期(图2中的T1~T5为一个周期)内碰的次数不超过1。
或者,S201中,跳频图案的标识信息可以为签名序列。
例如当频域的频带粒度为资源块级别时,网络设备可以基于跳频图案对终端设备指示如下的签名序列S
i:
其中i表示第i个终端设备/跳频图案,签名序列的行表示频带,列表示跳频时刻,元素取1表示在一个跳频时刻选择一个频带,元素取0表示在一个跳频时刻没有选择一个频带。该S
i表示第i个用户设备,在五个跳频时刻的频带选择分别RB2(频点F2)、RB1(频点F1)、RB4(频点F4)、RB3(频点F3)以及RB1(频点F1)。
又如,当频域的频带粒度为资源元素级别时,网络设备可以基于跳频图案对终端设备指示如下的签名序列S
i:
其中i表示第i个终端设备/跳频图案,签名序列的行表示频带,列表示跳频时刻,元素取1表示在一个跳频时刻选择一个频带,元素取0表示在一个跳频时刻没有选择一个频带。该S
i表示第i个用户设备,在五个跳频时刻的频带选择RE4-RE6(频点F2)、RE1-RE3(频点F1)、RE10-RE12(频点F4)、RE7-RE9(频点F3)以及RE1-RE3(频点F1)。
签名序列可以为稀疏序列。其中非零元素1用来指示终端设备对频域上一个或多个(即元素1可对应一个或多个RB)、连续或非连续资源(即资源在频域是可以连续或不连续,此时第二个签名矩阵中每一列的1可以不连续)的选择。
下面结合仿真结果,对本申请实施例提供的跳频图案指示方法的误块率(block error rate,BLER)进行说明。
如图4所示,在预配置(configured)的上行数据传输场景,基于理想信道估计、相同信噪比(signal-to-noise ratio,SNR)的情况下,本申请实施例提供的跳频指示方法中,终端设备在随机跳频(Random Hopping)或根据指示跳频(Proposed Hopping)下的BLER均比目前的频分多路复用((frequency-division multiplexing,FDM)与非正交多址接入(nonorthogonal multiple access,NOMA)结合方式下的BLER更低。
如图5所示,在预配置(configured)的上行数据传输场景,基于实际信道估计、相同SNR的情况下,本申请实施例提供的跳频指示方法中,终端设备在Random Hopping或Proposed Hopping下的BLER均比目前的FDM+NOMA结合方式下的BLER更低。
