Description

一种信号传输方法、相关设备及系统 技术领域
本发明涉及无线通信技术领域，尤其涉及一种信号传输方法、相关设备及系统。
背景技术
无线通信技术的飞速发展，导致频谱资源日益紧缺，促进了对于非授权频段的探索。然而对于非授权频段的使用，有诸多法规限制。一方面，对非授权频段的信号的信道带宽占用率(Occupancy Channel Bandwidth，OCB)有所限制。欧洲电信标准协会(European Telecommunications Standards Institute，ETSI)规定，在2.4GHz以及5GHz频段，要求信号的传输带宽要占用系统带宽的80％以上，而对于60GHz频段，则要求信号的传输带宽要占用系统带宽的70％以上。而对于传输功率，在5150-5350MHz频段，要求信号的最大功率谱密度为10dBm/MHz。另一方面，在非授权频段进行传输的设备需要先监听非授权频谱是否空闲，比如通过非授权频谱上的接收功率的大小来判断其忙闲状态，如果接收功率小于一定门限，则认为非授权频谱处于空闲状态，可以在所述非授权频谱上发送信号，否则不发送信号。这种先监听后发送的机制被称作先听后说(Listen Before Talk，简称LBT)。
对于下行传输而言，基站可以充分利用频谱资源满足ESTI的规定。但是，对于上行传输，上述规定的限制无疑给上行资源的分配带来巨大挑战。
在LTE Release13版本中，在上行传输时引入了增强型授权辅助接入(Enhanced Licensed Assisted Access，eLAA)技术。为了能够充分利用非授权频段，又能满足ESTI的OCB规定，eLAA采用资源交错(interlace)结构。上行资源分配以资源交错(interlace)为基本单位，分配给每个终端的资源至少为一个资源交错(interlace)。如图1所示，假设系统带宽是20MHz，20MHz的系统带宽对应100个RB(RB0～RB99)，每个资源交错(interlace)由均匀分布在整个带宽上的10个资源块(Resource Block，RB)构成，而且每个资源交错(interlace)中的RB两两间隔10个RB。这样可以保证每个interlace形成的频域跨度(位于首尾的两个RB之间的带宽跨度)是91个RB，约16.38MHz，大于系统带宽20MHz的80％。
但是，现有的资源交错(interlace)的结构固定，不够灵活，难以适应未来灵活带宽的场景。
发明内容
本申请提供一种信号传输方法、相关设备及系统，可实现更灵活的资源分配，且在一定时间内累计传输带宽满足OCB要求。
第一方面，本申请提供了一种信号传输方法，应用于网络设备侧，该方法可包括：网络设备可以向终端发送资源调度信息和跳频信息，该资源调度信息用于指示网络设备分配给终端的第二资源集合，该跳频信息用于指示第二资源集合关联的频率跳变图样。然后，网络设备可以接收终端发送的上行信号。

在本申请提供的频率跳变图样中，上行传输占用多个时间单元，其中，每一个时间单元上的用于上行传输的资源块的资源结构与第二资源集合的资源结构相同，相邻时间单元上的用于上行传输的资源块的频率位置不同。这里，时间单元即跳频周期，可以是以下至少一项的整数倍：符号(symbol)、微时隙(mini-slot)、时隙(slot)或子帧(subframe)。
实施第一方面和第二方面描述的方法，可以保证上行传输在一定时间(多个跳频周期)内累积占用的带宽满足OCB要求，而且可实现更灵活的资源分配。

具体实施方式
本发明的实施方式部分使用的术语仅用于对本发明的具体实施例进行解释，而非旨在限定本发明。
为了便于了解本发明实施，首先介绍本申请涉及的无线通信系统。
参考图2，图2示出了本申请涉及的无线通信系统200。无线通信系统200可以工作在授权频段，也可以工作在非授权频段。可以理解的，非授权频段的使用可以提高无线通信系统200的系统容量。如图2所示，无线通信系统200包括：一个或多个网络设备(Base Station)201，例如NodeB、eNodeB或者WLAN接入点，一个或多个终端(Terminal)203，以及核心网215。其中：
网络设备201可用于在网络设备控制器(如基站控制器)(未示出)的控制下与终端203通信。在一些实施例中，所述网络设备控制器可以是核心网230的一部分，也可以集成到网络设备201中。
网络设备201可用于通过回程(blackhaul)接口(如S1接口)213向核心网215传输控制信息(control information)或者用户数据(user data)。
网络设备201可以通过一个或多个天线来和终端203进行无线通信。各个网络设备201均可以为各自对应的覆盖范围207提供通信覆盖。接入点对应的覆盖范围207可以被划分为多个扇区(sector)，其中，一个扇区对应一部分覆盖范围(未示出)。
网络设备201与网络设备201之间也可以通过回程(blackhaul)链接211，直接地或者间接地，相互通信。这里，所述回程链接211可以是有线通信连接，也可以是无线通信连接。
在本申请的一些实施例中，网络设备201可以包括：基站收发台(Base Transceiver Station)，无线收发器，一个基本服务集(Basic Service Set，BSS)，一个扩展服务集(Extended Service Set，ESS)，NodeB，eNodeB等等。无线通信系统200可以包括几种不同类型的网络设备201，例如宏基站(macro base station)、微基站(micro base station)等。网络设备201可以应用不同的无线技术，例如小区无线接入技术，或者WLAN无线接入技术。

基于前述无线通信系统200、终端300以及网络设备400分别对应的实施例，本申请提供了一种信号传输方法。
本申请的主要发明原理可包括：对于非授权频段的上行传输，网络设备为终端分配至少一个资源块。该至少一个资源块可以来自第一资源集合，即由第一资源集合中的部分资源块构成。其中，第一资源集合为在频域上均匀分布的整数个资源块。可选的，第一资源集合可以为资源交错(interlace)。该至少一个资源块依从规定的频率跳变图样(frequency hopping pattern)。也即是说，上行传输可以占用多个时间单元，其中，每一个时间单元上的用于上行传输的资源块的资源结构与所述第二资源集合的资源结构相同，相邻时间单元上的用于上行传输的资源块的频率位置不同。这样，可以保证上行传输在一定时间(多个跳频周期)内累积占用的带宽满足OCB要求，而且可实现更灵活的资源分配。
本申请中，网络设备分配给终端的上述至少一个资源块可以称为第二资源集合。
为了便于理解本申请的主要发明原理，下面举例说明。
图5示例性的示出了第二资源集合依从规定的频率跳变图样经历频率跳变后的资源图样(pattern)。假设系统带宽为100个RB，一个interlace包括10个RB，interlace中相邻RB之间的间隔为10个RB。或者，假设系统带宽为106个RB，一个interlace包括10个或者11个RB，interlace中相邻RB之间的间隔为10个RB。
如图5所示，网络设备为终端1分配3个资源块(即第二资源集合)，这3个资源块可以是一个interlace(即第一资源集合)中的前3个资源块：RB0、RB10、RB20。这3个资源块每隔一个跳频周期(在本实施例中，一个跳频周期为一个时间单元)进行一次频率跳变，且跳频偏移量为20个RB。具体的，在第0个跳频周期内，用于上行传输的资源块为： RB0、RB10、RB20。在第1个跳频周期内，RB0跳至RB20，RB10跳至RB30，RB20跳至RB40，即用于上行传输的资源块为RB20、RB30、RB40。依次类推，在第0-3个跳频周期内，用于上行传输的资源块为：RB0、RB10、RB20、RB30、RB40、…RB80。也即是说，第0-4个跳频周期内，上行传输累积占用的带宽跨度为91个RB，这91个RB的带宽占用率等于90*0.18M/40M＝81.9％。也即是说，这91个RB在系统带宽中的占比大于80％，满足OCB要求。
图5仅仅用于解释本申请，不应构成限定。
本申请中，网络设备分配给终端的第二资源集合依从规定的频率跳变图样(frequency hopping pattern)可表示用于上行传输的资源块。参考图5可以看出，用于上行传输的资源块分布在多个时间单元上，其中，每一个时间单元上的用于上行传输的资源块的资源结构与第二资源集合的资源结构相同，第1个时间单元上的用于上行传输的资源块即第二资源集合，相邻时间单元上的用于上行传输的资源块的频率位置可以相差指定的跳频偏移量(hopping offset)。
本申请中，上述资源结构相同是指资源块数量相同、相邻资源块之间的间距相同。在图5的示例中，每一个跳频周期上的用于上行传输的资源块的数量均是3个，与网络设备分配给终端的资源块(RB0、RB10、RB20)的数量相同。每一个跳频周期上的相邻的用于上行传输的资源块之间间距10个RB，与网络设备分配给终端的相邻资源块之间的间距(10个RB)相同。
本申请中，第二资源集合的频率跳变可以是基于整个跳频带宽(如系统带宽或子带)的循环跳频。例如，如图5所示，在第5个跳频周期内，RB60跳至RB80，RB70跳至RB90，RB80跳至RB0，其中，由于RB90是interlace中的最后一个RB，因此RB80循环跳至RB0。
这里，该时间单元可以为跳频周期(hopping period)，跳频周期(hopping period)可以是以下至少一项的整数倍：符号(symbol)、微时隙(mini-slot)、时隙(slot)或子帧(subframe)。
本申请的实施方式中，子带(subband)是指一个或多个载波，或者一个载波上的部分子载波或者部分资源块等。在一些场景下，子带也可以是带宽子集(bandwidth part，BWP)，是指系统带宽中的部分带宽。
本申请中，网络设备可以向终端发送资源调度信息，该资源调度信息可用于指示网络设备为终端分配的第二资源集合，即上述至少一个资源块。终端接收到该资源调度信息后，可以依据规定的频率跳变图样对网络设备分配的上述至少一个资源块进行跳频，确定用于上行传输的资源块。这里，用于上行传输的资源块的定义和说明可参考前述内容，这里不再赘述。最终，终端可以通过LBT在空闲的用于上行传输的资源块上进行上行传输。可以理解的，在非授权频段，网络设备和终端在传输信号前，均需要进行LBT。最终，终端可以在空闲的频率资源上进行上行传输。
(1)资源调度信息的信令实现
可选的，网络设备可以将资源调度信息携带在下行控制信息(Downlink Control Information，DCI)中。具体的，可以在DCI中新增一个字段，该字段用于指示分配给终端的第二资源集合，即至少一个资源块。
例如，网络设备可以将资源调度信息携带在返回给终端的上行调度授权(UL grant)中。 这里，UL grant即DCI的一种，采用DCI format0/0A/0B/4/4A/4B。
可选的，网络设备还可以在针对终端的调度请求(scheduling request，SR)的其他应答消息中携带资源调度信息，或者网络设备还可以将资源调度信息独立封装成一个消息，返回该消息给终端。关于如何发送资源调度信息的方式(即信令实现)，本申请不作限制。
(2)资源调度信息的内容实现。
第一种实现方式，资源调度信息可包括：第二资源集合所属的第一资源集合的索引、第二资源集合在第一资源集合中的索引。例如，在图5的示例中，假设网络设备从interlace0(即第一资源集合)中分配RB0、RB10、RB20给终端，那么，资源调度信息可包括：interlace0的索引“0”，以及RB0、RB10、RB20分别在interlace0中的索引“0”、“1、“2””。示例仅仅用于解释本申请，不应构成限定。
可选的，资源调度信息还可包括：第一资源集合中相邻资源块之间的间距。可选的，第一资源集合中相邻资源块之间的间距可以由协议定义。
第二种实现方式，资源调度信息可包括：第二资源集合所属的第一资源集合的索引、第二资源集合在第一资源集合中的索引、第二资源集合所处的子带的索引。
在第二种实现方式中，第一资源集合可以为均匀分布在子带上的整数个资源块。网络设备分配给终端的第二资源集合可以由同一个子带上的至少一个第一资源集合中的部分资源块构成。网络设备分配给终端的第二资源集合可以由不同子带上的至少一个第一资源集合中的部分资源块构成。关于第二种实现方式的详细说明，可参考后续图9和图10实施例，这里先不赘述。
可选的，资源调度信息还可包括：第一资源集合中相邻资源块之间的间距。可选的，第一资源集合中相邻资源块之间的间距可以由协议定义。
第三种实现方式，资源调度信息可包括：第二资源集合中的资源块的资源块编号。
具体实现中，可以对整个系统带宽内的资源块进行编号，利用资源块编号即可指示出具体的资源块。这里，资源块编号也可以称为资源块索引。例如，在图5的示例中，资源调度信息可包括：RB0、RB10、RB20分别在整个系统带宽内的编号：“0”、“10”、“20”。示例仅仅用于解释本申请，不应构成限定。
不限于上述几种实现方式，资源调度信息的内容还可以通过其他方式实现。即网络设备和终端之间还可以约定其他的方式来指示网络设备调度给终端的第二资源集合，即上述至少一个资源块。
本申请的一个实施例中，网络设备分配给终端的第二资源集合所依从的规定的频率跳变图样可以由网络设备通知给终端。具体的，网络设备可以向终端发送跳频信息。
(1)跳频信息的信令实现
可选的，网络设备可以将跳频信息和资源调度信息都携带在下行控制信息(DCI)中。可选的，可以在DCI中新增两个字段，其中，一个新增字段用于指示分配给终端的第二资源集合，另一个新增字段用于指示上述频率跳变图样。
例如，网络设备可以将跳频信息和资源调度信息都携带在返回给终端的上行调度授权(UL grant)中。这里，UL grant即DCI的一种，采用DCI format0/0A/0B/4/4A/4B。
可选的，网络设备可以在针对终端的调度请求(scheduling request，SR)的其他应答消 息中同时携带跳频信息和资源调度信息，或者网络设备还可以将跳频信息和资源调度信息一起独立封装成一个消息，返回该消息给终端。
可选的，网络设备可以将跳频信息和资源调度信息分别携带在不同的消息中。关于如何发送资源调度信息的方式(即信令实现)，本申请不作限制。
(2)跳频信息的内容实现。
具体的，该跳频信息可包括以下至少一项：第二资源集合关联的跳频偏移量N hopping_offset、第二资源集合关联的跳频总带宽或第二资源集合关联的跳频周期。
在本申请的另一个实施例中，网络设备与终端可以预先约定频率跳变图样，或者该频率跳变图样由协议预先规定，网络设备与终端均遵循协议的规定。因此，无需网络设备向终端发送跳频信息。其中，跳频信息中的一项或多项可以由协议定义。例如，协议可以定义跳频偏移量为10个RB，或者定义跳频周期为1个微时隙等。在不同的实施例中，通讯协议中可以体现为频率跳变图样，网络设备或者终端依照该频率跳变图样来进行频率跳变。示例仅仅用于解释本申请，不应构成限定。
不限于资源交错(interlace)，本申请中涉及的第一资源集合还可以为呈现其他资源结构的多个资源块，只要第一资源集合中的资源块在频域上均匀分布即可。不限于ESTI的OCB规定，对于未来以及其他针对信号的信道带宽占用率在规定和要求的场景，本申请提供的技术方案同样适用。
下面通过多个实施例详细介绍如何对分配给终端的资源块进行频率跳变。
(一)实施例一
本实施例中，系统带宽被划分成多个第一资源集合，第一资源集合由均匀分布在整个系统带宽上的多个RB组成。可选的，第一资源集合可以采用如eLAA中的interlace结构。在进行资源分配时，网络设备采用第一资源集合中的部分连续的RB作为第二资源集合。也即是说，网络设备分配给终端的第二资源集合资源块由第一资源集合中的整数个连续的资源块构成。
然后，网络设备可以向终端发送资源调度信息以及跳频信息，其中，资源调度信息用于指示网络设备分配给终端的第二资源集合，跳频信息用于指示第二资源集合关联的跳频方式。相应的，终端可以根据网络设备的调度，在相应的资源上进行上行跳频传输。可选的，跳频方式(如跳频偏移量N hopping_offset、跳频总带宽

跳频周期)也可以由协议定义，网络设备无需向终端发送跳频信息。需要说明的是，在非授权频段，网络设备和终端在传输信号前，均需要进行LBT。
具体的，网络设备分配给终端的第二资源集合可表示为：RB START+l+i·N，其中，RB START表示分配给所述终端的起始资源块的索引；l∈L，集合L包括第二资源集合所属的第一资源集合的索引；N表示第一资源集合中两个相邻RB之间的间距；i∈M,集合M包括第二资源集合中的资源块在第二资源集合所属的第一资源集合中的索引。
具体的，在进行频率跳变时，网络设备分配给终端的第二资源集合周期性地在频域上 进行跳变。第p个跳频周期内用于上行传输的资源块集合为：

其中，

表示第p-1个跳频周期内用于上行传输的起始RB的索引；N hopping_offset为跳频偏移量。
这里，多个跳频周期内用于上行传输的资源块包括该多个跳频周期中各个跳频周期内用于上行传输的资源块。
本实施例中，跳频周期可以是以下至少一项的整数倍：symbol、mini-slot、slot或subframe。
下面以图6为例，说明实施例一的具体实施。
假设1：系统带宽为20MHz，子载波间隔为15kHZ，传输带宽为
Figure PCTCN2018104233-appb-000020
第一资源集合为均匀分布在频域上的10个RB构成的interlace(如图6中的RB#0，RB#10，RB#20，…，RB#80，RB#90)。资源分配从RB0开始(即RB START＝0)。
假设2：第一资源集合中相邻两个RB之间的间隔(即RB间隔)为10个RB。跳频偏移量(hopping offset)为20个RB。
网络设备分配给终端的第二资源集合为：RB START+l+i·N，其中，RB START＝0，l∈L，L＝{0}，i∈M，M＝{0,1,2}，N＝10。那么，第二资源集合为：

上面这个集合表示的资源块即图6中的RB#0、RB#10、RB#20，为第0个跳频周期内用于上行传输的资源块。

那么，
第1个跳频周期内用于上行传输的资源块为：20+{0}+{0，1，2}*10＝{20,30,40}，即RB#20、RB#30、RB#40。

参考图6可以看出，通过跳频，网络设备分配给终端的资源块(RB#0、RB#10、RB#20)在一定时间内(第0个至第4个跳频周期内)累积占用的带宽跨度为91个RB，这91个RB的带宽占用率等于90*0.18M/20M＝81.9％。也即是说，这91个RB在系统带宽中的占比大于80％，满足OCB要求。而且，网络设备无需以整个interlace为基本调度单元，显著缩小了资源调度的粒度，提高了资源调度的灵活性。
以下以图12为例，进一步说明实施例一的具体实施方式
假设1：系统带宽为20MHz，子载波间隔为15kHZ，传输带宽为106个RB。第一资源集合为均匀分布在频域上的10个或者11个RB构成的interlace(如图6中，interlace#0对应RB#0，RB#10，RB#20，…，RB#80，RB#90，RB#100这11个RB，而interlace#9对应RB#9，RB#19，RB#29，…，RB#89，RB#99这10个RB)。资源分配从RB0开始(即RB START＝0)。
假设2：第一资源集合中相邻两个RB之间的间隔(即RB间隔)为10个RB。跳频偏移量(hopping offset)为20个RB。
网络设备分配给终端的第二资源集合为：RB START+l+i·N，其中，RB START＝0，l∈L，L＝{0}，i∈M，M＝{0,1,2}，N＝10。那么，第二资源集合为：

第p个跳频周期内用于上行传输的资源块集合为：
Figure PCTCN2018104233-appb-000038
那么，
第1个跳频周期内用于上行传输的资源块为：(20+{0}+{0，1，2}*10)mod106＝{20,30,40}，即RB#20、RB#30、RB#40。
第2个跳频周期内用于上行传输的资源块为：(40+{0}+{0，1，2}*10)mod106＝{40,50,60}，即RB#40、RB#50、RB#60。
第3个跳频周期内用于上行传输的资源块为：(60+{0}+{0，1，2}*10)mod106＝{60,70,80}，即RB#60、RB#70、RB#80。

第6个跳频周期内用于上行传输的资源块为：(14+{0}+{0，1，2}*10)mod106＝{14,24,34}，即RB#14、RB#24、RB#34。
从此可以看出，跳频可以是基于跳频总带宽(106个RB)的循环跳频。
后续各个跳频周期内用于上行传输的资源块可依此类推，不再赘述。
可选的，如图13所示，跳频也可以是基于第一资源集合的循环跳频。即每个跳频周期内用于上行传输的第二资源集合的RB索引为根据跳频偏移在所述第二资源集合所属的第一资源集合对应的所有RB索引中进行循环。
参考图7可以看出，通过跳频，网络设备分配给终端的资源块(RB#0、RB#10、RB#20)在一定时间内(第0个至第4个跳频周期内)累积占用的带宽跨度为91个RB，这91个RB的带宽占用率等于90*0.18M/20M＝81.9％。也即是说，这91个RB在系统带宽中的占比大于80％，满足OCB要求。而且，网络设备无需以整个interlace为基本调度单元，显著缩小了资源调度的粒度，提高了资源调度的灵活性。
(二)实施例二

假设1：系统带宽为20MHz，子载波间隔为15kHZ，传输带宽为106个RB。第一资源集合为均匀分布在频域上的10个或者11个RB构成的interlace构成(例如，interlace#0对应RB#0，RB#10，RB#20，…，RB#80，RB#90，RB#100这11个RB，而interlace#9对应RB#9，RB#19，RB#29，…，RB#89，RB#99这10个RB)。资源分配从RB0开始(即RB START＝0)。
假设2：第一资源集合中相邻两个RB之间的间隔(即RB间隔)为10个RB。跳频偏移量(hopping offset)为20个RB。
网络设备分配给终端的第二资源集合为：RB START+l+i·N，其中，RB START＝0，l∈L，L＝{0,1}，i∈M，M＝{0,1,2}&{0,1}，N＝10。那么，第二资源集合为：
0+{0，1}+{0，1，2}&{0，1}*10＝{0,10,20}&{1,11}
上面2个集合分别表示interlace#0中的RB#0、RB#10、RB#20，以及interlace#1中的RB#1、RB#11。

后续各个跳频周期内用于上行传输的起始RB可依此类推，不再赘述。
第p个跳频周期内用于上行传输的资源块集合为：
Figure PCTCN2018104233-appb-000089
那么，
第1个跳频周期内用于上行传输的资源块为：(20+{0，1}+{0，1，2}&{0，1}*10)mod106＝{20,30,40}&{21,31}，即RB#20、RB#30、RB#40，以及RB#21、RB#31。
第2个跳频周期内用于上行传输的资源块为(40+{0，1}+{0，1，2}&{0，1}*10)mod106＝{40,50,60}&{41,51}，即RB#40、RB#50、RB#60，以及RB#41、RB#51。

从此可以看出，跳频可以是基于跳频总带宽(106个RB)的循环跳频。后续各个跳频周期内用于上行传输的资源块可依此类推，不再赘述。
可选的，跳频也可以是基于第一资源集合的循环跳频。即每个跳频周期内用于上行传输的第二资源集合的RB索引为根据跳频偏移在所述第二资源集合所属的第一资源集合对应的所有RB索引中进行循环。
参考图8可以看出，通过跳频，网络设备分配给终端的资源块(interlace#0中的RB#0、RB#10、RB#20，以及interlace#0中的RB#1、RB#11)在一定时间内(第0个至第3个跳频周期内)累积占用的带宽跨度为91个RB，这91个RB的带宽占用率等于90*0.18M/20M＝81.9％。也即是说，这91个RB在系统带宽中的占比大于80％，满足OCB要求。而且，网络设备无需以整个interlace为基本调度单元，显著缩小了资源调度的粒度，提高了资源调度的灵活性。
在上述3个实施例中，第一资源集合为均匀分布在整个系统带宽上的整数个资源块，其中，这整数个资源块的资源结构可以与系统带宽和/或子载波间隔相关。
在本申请的一些实施例中，为了适应多种系统带宽和/或多种子载波间隔的场景，第一资源集合可以包含H个资源块，H是正整数，H能够被非授权频段对应的多种传输带宽各自对应的资源块总数量整除。
下面举例说明。
首先，以5GHz频段为例，未来新空口(NR)通信技术中可支持的系统带宽有20MHz，40MHz，80MHz，160MHz等，可选的子载波间隔有15KHz，60KHz等。
(一)对于15KHz子载波间隔，上述各种系统带宽场景各自对应的传输带宽可能分别为100个RB，200个RB，400个RB，800个RB。兼容上述各种系统带宽的场景的资源交错(interlace)的结构可以有如下几种：
(1)每个资源交错由10个RB构成。在上述各种系统带宽的场景，一个资源交错占用的带宽分别为91个RB，181个RB，361个RB，721个RB。
(2)每个资源交错由25个RB构成。在上述各种系统带宽的场景，一个资源交错占用的带宽分别为97个RB，193个RB，385个RB，769个RB。
可以理解的，对于15KHz子载波间隔，(1)和(2)两种资源交错包含的资源块个数都可以被上述各种系统带宽对应的资源块总数整除。
(二)对于60KHz子载波间隔，上述各种系统带宽场景对应的传输带宽可能分别为25个RB，50个RB，100个RB，200个RB。兼容上述各种系统带宽的场景的资源交错(interlace)的结构可为：每个资源交错由25个RB构成。在上述各种系统带宽的场景，一个资源交错占用的带宽分别为25个RB，49个RB，97个RB，193个RB。
综上，对于5GHz频段的上行资源分配，可存在如下两种方案：
(1)为了兼容所有的场景(15KHz或60KHz子载波间隔)，可以固定采用25RB/interlace(即每一个资源交错包含25个RB)的方案。
(2)为了适应多种业务需求，可以同时支持10RB/interlace和25RB/interlace这两种结构。在进行资源分配指示时，还需要interlace的类型信息(10RB/interlace或25RB/interlace)携带在所述资源指示信息中。
也即是说，在5GHz频段上，分配给终端的第二资源集合可以由不同结构的多个资源交错中的部分RB构成。
需要说明的，上述关于5GHz频段的举例分析仅仅用于解释本发明实施例，上述各种系统带宽场景中的传输带宽、子载波间隔等具体参数的实际取值均以未来标准中的定义为准。
其次，以60GHz频段为例，未来新空口(NR)通信技术中可支持的系统带宽有500MHz，1GHz，2GHz等，可选的子载波间隔有480kHz，960kHz(仅系统带宽2GHz支持)等。
(一)对于480kHz子载波间隔，上述各种系统带宽场景各自对应的传输带宽可能分别为78个RB，156个RB，312个RB。兼容上述各种系统带宽的场景的资源交错(interlace)的结构可如下：每个资源交错由6个RB构成。在上述各种系统带宽的场景，一个资源交错占用的带宽分别为66个RB，131个RB，261个RB。
(二)对于960kHz子载波间隔，2GHz系统带宽对应的传输带宽可为156个RB。适应2GHz系统带宽场景的资源交错(interlace)的结构可如下：每个资源交错由6个RB构成。在2GHz系统带宽场景中，一个资源交错占用的带宽为131个RB。
综上，对于60GHz频段的上行资源分配可以固定采用6RB/interlace(即每一个资源交错包含6个RB)的方案。
需要说明的，上述关于60GHz频段的举例分析仅仅用于解释本发明实施例，上述各种系统带宽场景中的传输带宽、子载波间隔等具体参数的实际取值均以未来标准中的定义为准。
在本申请的一些实施例中，为了支持不同带宽之间的资源对齐，第一资源集合中的RB间隔(RB spacing)可以是固定值。这里，RB间隔是指第一资源集合中的任意2个相邻RB之间的间隔。
例如，在20MHz、40MHz、80MHz或120MHz等带宽下，每个资源交错的RB间隔N均为10。这样，当终端通过LBT监听到的可接入带宽与网络设备调度的带宽不一致时，终端也可以进行上行传输，无需等待网络设备重新进行资源调度，可实现灵活带宽传输。
本申请中，系统带宽(或子带)上的多个第一资源集合(如interlace)可以采用相同的资源结构，也可以采用不同的资源结构。这里，资源结构可主要是指第一资源集合(如interlace)中的资源块数量或相邻资源块之间的间隔中的至少一项。
不限于上述3个实施例，第一资源集合也可以为均匀分布在单个子带上的整数个资源块。下面通过图9-图10实施例来说明。
(四)实施例四
本实施例中，系统带宽被划分成多个子带。各个子带上的资源分配可以是独立的或者相同的。在进行资源分配时，网络设备采用同一个子带上的第一资源集合中的部分RB作为基本调度单元。也即是说，网络设备分配给终端的第二资源集合由同一个子带上的至少一个第一资源集合中的部分资源块构成。
具体的，网络设备分配给终端的第二资源集合可表示为：RB START+l+i·N，其中，RB START表示分配给所述终端的起始资源块的索引；l∈L，集合L包括单个子带上第二资源集合所属的第一资源集合的索引；N表示第一资源集合中两个相邻RB之间的间距；i∈M,集合M包括单个子带上分配给终端的资源块在第二资源集合所属的第一资源集合中的索引。
具体的，在进行频率跳变时，网络设备分配在单个子带上给终端的第二资源集合周期性地在子带上进行跳变。第p个跳频周期内用于上行传输的资源块集合可表示为：

由两个20MHz的子带构成，各个子带的带宽
Figure PCTCN2018104233-appb-000097
各个子带上的第一资源集合为均匀分布在频域上的10个RB构成的interlace(如图9中的子带#0上的interlace#0为RB#0，RB#10，RB#20，…，RB#80，RB#90、子带#1上的interlace#0为RB#100，RB#110，RB#120，…，RB#180，RB#190。
假设2：各个子带上的第一资源集合中相邻两个RB之间的间隔(即RB间隔)为10个RB。子带#0上的跳频偏移量(hopping offset)为20个RB，子带#1上的跳频偏移量(hopping offset)为30个RB。子带#0上的资源分配从RB#0开始(即RB START＝0)。子带#1上的资源分配从RB#100开始(即RB START＝100)。
网络设备分配给终端1的第二资源集合为：RB START+l+i·N，其中，RB START＝0，l∈L，L＝{0}，i∈M，M＝{0,1}，N＝10。那么，第二资源集合为：
0+{0}+{0，1}*10＝{0,10}
上面这个集合表示的资源块即图9中的RB#0、RB#10，为终端1在子带#0上的第0 个跳频周期内用于上行传输的资源块。

为：(20+20)mod100＝40，即RB#40。
后续各个跳频周期内用于上行传输的起始RB可依此类推，不再赘述。
对于终端1，第p个跳频周期内用于上行传输的资源块集合为：
Figure PCTCN2018104233-appb-000104
那么，
第1个跳频周期内用于上行传输的资源块为：(20+{0}+{0，1}*10)mod100＝{20,30}，即RB#20、RB#30。
第2个跳频周期内用于上行传输的资源块为：(40+{0}+{0，1}*10)mod100＝{40,50}，即RB#40、RB#50。
终端1在后续各个跳频周期内用于上行传输的资源块可依此类推，不再赘述。
同样的，可以推导出：
网络设备分配给终端2的第二资源集合为：RB START+l+i·N，其中，RB START＝100，l∈L，L＝{0}，i∈M，M＝{0,2,4}，N＝10。那么，第二资源集合为：
100+{0}+{0，2，4}*10＝{100,120,140}
上面这个集合表示的资源块即图9中的RB#100、RB#120、RB#140，为终端2在子带#1上的第0个跳频周期内用于上行传输的资源块。
对于终端2，RB START＝100(子带#1上的第0个跳频周期内用于上行传输的起始RB)，N hopping_offset＝30，
Figure PCTCN2018104233-appb-000105

为：(100+30)mod100+100＝130，即RB#130。
第2个跳频周期内用于上行传输的起始
Figure PCTCN2018104233-appb-000107
为：(130+30)mod100+100＝160，即RB#160。
后续各个跳频周期内用于上行传输的起始RB可依此类推，不再赘述。
对于终端2，第1个跳频周期内用于上行传输的资源块集合为：(130+{0}+{0，2,4}*10)mod100+100＝{130,150,170}，即RB#130、RB#150、RB#170。
对于终端2，第2个跳频周期内用于上行传输的资源块集合为：(160+{0}+{0，2,4}*10)mod100+100＝{160,180,100}，即RB#160、RB#180、RB#100。从此可以看出，跳频可以是 基于子带为总跳频带宽的循环跳频。
终端2在后续各个跳频周期内用于上行传输的资源块可依此类推，不再赘述。
参考图9可以看出，通过跳频，网络设备在子带上分配给各个终端的资源块(如子带#0上的interlace#0中的RB#0、RB#10)在一定时间内(第0个至第4个跳频周期内)累积占用的带宽跨度为91个RB，这91个RB的带宽占用率等于90*0.18M/20M＝81.9％。也即是说，这91个RB在单个子带中的占比大于80％，满足OCB要求。而且，资源调度的粒度显著缩小了，提高了资源调度的灵活性。
(五)实施例五
本实施例中，系统带宽被划分成多个子带。各个子带上的资源分配可以是独立的或者相同的。在进行资源分配时，网络设备采用不同子带上的第一资源集合中的部分RB作为基本调度单元。也即是说，网络设备分配给终端的第二资源集合由不同子带上的至少一个第一资源集合中的部分资源块构成。
具体的，在单个子带上，网络设备分配给终端的第二资源集合可表示为：RB START+l+i·N，其中，RB START表示在单个子带上网络设备分配给所述终端的起始资源块的索引；l∈L，集合L包括单个子带上第二资源集合所属的第一资源集合的索引；N表示第一资源集合中两个相邻RB之间的间距；i∈M,集合M包括单个子带上分配给终端的资源块在第二资源集合所属的第一资源集合中的索引。
具体的，在进行频率跳变时，网络设备在单个子带上分配给终端的第二资源集合周期性地在子带上进行跳变。第p个跳频周期内用于上行传输的资源块集合可表示为：

下面以图10为例，说明实施例五的具体实施。
假设1：系统带宽为40MHz，子载波间隔为15kHZ。传输带宽为
Figure PCTCN2018104233-appb-000114
由两个20MHz的子带构成，各个子带的带宽
Figure PCTCN2018104233-appb-000115
各个子带上的第一资源集合为均匀分布在频域上的10个RB构成的interlace(如图10中的子带#0上的interlace#0为RB#0，RB#10，RB#20，…，RB#80，RB#90、子带#1上的interlace#0为RB#100，RB#110，RB#120，…，RB#180，RB#190。
假设2：各个子带上的第一资源集合中相邻两个RB之间的间隔(即RB间隔)为10个RB。子带#0上的跳频偏移量(hopping offset)为20个RB，子带#1上的跳频偏移量(hopping offset)为30个RB。子带#0上的资源分配从RB#0开始(即RB START＝0)。子带#1上的资 源分配从RB#100开始(即RB START＝100)。
在子带#0上，网络设备分配给终端1的资源块为：RB START+l+i·N，其中，RB START＝0，l∈L，L＝{0}，i∈M，M＝{0,1}，N＝10。那么，第二资源集合为：
0+{0}+{0，1}*10＝{0,10}
在子带#1上，网络设备分配给终端1的资源块为：RB START+l+i·N，其中，RB START＝100，l∈L，L＝{0}，i∈M，M＝{0,2,4}，N＝10。那么，第二资源集合为：
100+{0}+{0，2，4}*10＝{100，120，140}
也即是说，在子带#0和子带#1上，网络设备分配给终端1的第二资源集合为：{0,10}&{100,120，140}。
在子带#1上，第1个跳频周期内用于上行传输的资源块集合为：(20+{0}+{0，1}*10)mod100＝{20,30}，即RB#20、RB#30。
在子带#2上，第1个跳频周期内用于上行传输的资源块集合为：(130+{0}+{0，2,4}*10)mod100+100＝{130,150,170}，即RB#130、RB#150、RB#170。
也即是说，在子带#0和子带#1上，第1个跳频周期内用于上行传输的资源块集合为：{20,30}&{130,150,170}。
在子带#1上，第2个跳频周期内用于上行传输的资源块集合为：(40+{0}+{0，1}*10)mod100＝{40,50}，即RB#40、RB#50。
在子带#2上，第2个跳频周期内用于上行传输的资源块集合为：(160+{0}+{0，2,4}*10)mod100+100＝{160,180,100}，即RB#160、RB#180、RB#100。
也即是说，在子带#0和子带#1上，第2个跳频周期内用于上行传输的资源块集合为：{40,50}&{160,180,100}。
后续各个跳频周期内用于上行传输的资源块几个可依此类推，不再赘述。
参考图10可以看出，通过跳频，网络设备在不同子带上分配给各个终端的资源块(如子带#0上的interlace#0中的RB#0、RB#10，以及子带#1上的interlace#0中的RB#100、RB#120、RB#140)在一定时间内(第0个至第3个跳频周期内)累积占用的带宽跨度为191个RB，这191个RB的带宽占用率等于190*0.18M/40M＝85.5％。也即是说，这191个RB在系统带宽中的占比大于80％，满足OCB要求。而且，资源调度的粒度显著缩小了，提高了资源调度的灵活性。
在实施例四或实施例五中，各个子带上的第一资源集合的结构可以相同或不同。在单个子带上，网络设备可以调度一个或多个第一资源集合中的部分RB给终端。
可以理解的，在实施例四或实施例五中，对于系统传输带宽的举例，仅为了便于描述方案，不应构成限定。进行跳频时，可以在系统总传输带宽的范围内进行循环，或者可以下子带对应的传输带宽范围内进行循环，或者，在所述第二资源集合所述的第一资源集合内进行循环。
另外，在上述任意一个实施例中，为了便于网络设备的正确接收，在发送上行信号时，终端还可以向网络设备发送参考信号。其中，在上行传输占用的每一个时间单元内，承载该参考信号的资源可以与承载上行信号的资源块的频域位置相同。可选的，参考信号在时 域上可以位于每一个上行传输间隔中的指定位置(例如第一个符号)上。
参见图11，图11是本申请的一个实施例提供的无线通信系统10，以及无线通信系统10中的网络设备500、终端400。网络设备500可以是前述方法实施例中的上述网络设备，可用于接收终端的调度请求，在非授权频段上为终端分配上行信号传输资源。终端400可以是前述方法实施例中的上述终端，可以按照网络设备500的调度指示在LBT监听到的空闲带宽进行上行传输。
如图11所示，网络设备500可包括：接收单元501和发送单元503。其中：
发送单元503，可用于用于向终端400发送资源调度信息和跳频信息，其中资源调度信息用于指示网络设备分配给终端400的第二资源集合，跳频信息用于指示第二资源集合关联的跳频方式。其中，第二资源集合可以由第一资源集合中的部分资源块构成，第一资源集合为在频域上均匀分布的整数个资源块。
接收单元501，可用于接收终端400发送的上行信号，该上行信号承载于终端400监听到的空闲的用于上行传输的资源块上。这里，用于上行传输的资源块分布在多个时间单元上，其中，每一个时间单元上的用于上行传输的资源块的结构与第二资源集合的结构相同，相邻时间单元上的用于上行传输的资源块的频率位置相差第一偏移量。
如图11所示，终端400可包括：发送单元401和接收单元403。其中：
接收单元403，可用于接收网络设备500发送的资源调度信息，资源调度信息用于指示网络设备500分配给终端的第二资源集合。其中，第二资源集合可以由第一资源集合中的部分资源块构成，第一资源集合为在频域上均匀分布的整数个资源块。
发送单元401，可用于根据资源调度信息，在监听到的空闲的用于上行传输的资源块上进行上行传输。这里，用于上行传输的资源块可以分布在多个时间单元上，其中，每一个时间单元上的用于上行传输的资源块的结构与第二资源集合的结构相同，相邻时间单元上的用于上行传输的资源块的频率位置相差第一偏移量。
可选的，无需网络设备500向终端400发送跳频信息，网络设备500分配给终端400的第二资源集合所依从的规定的频率跳变图样(frequency hopping pattern)也可以由协议定义的。也即是说，跳频信息中的一项或多项可以由协议定义。例如，协议可以定义跳频偏移量为10个RB，或者定义跳频周期为1个微时隙等。示例仅仅用于解释本申请，不应构成限定。
本申请中，可以通过如下方式对网络设备500分配给终端400的资源块进行频率跳变。
第一种方式，基于整个系统带宽进行循环的频率跳变。这里，系统带宽被划分成多个第一资源集合，第一资源集合由均匀分布在整个系统带宽上的多个RB组成。
