Description

信息传输方法、终端设备及网络设备
本申请要求于2017年09月30日提交中国专利局、申请号为201710919936.8、申请名称为《信息传输方法、终端设备及网络设备》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，尤其涉及一种信息传输方法、终端设备及网络设备。
背景技术
现有的无线通信领域，频谱资源主要分为两种：许可频谱资源和免许可频谱资源。免许可频谱通常是共享频谱，可以允许多个通信系统使用该共享频谱进行数据通信。当通信设备使用免许可频谱资源进行数据通信时，需要遵从各地针对免许可频谱资源使用制定的规范，以实现不同的通信系统在免许可频谱上的共存。其中，各地针对免许可频谱资源使用制定的规范包括信道接入机制、发射功率限制、频谱资源占用率等方面。
在现有的长期演进(Long Term Evolution，LTE)系统及其演进系统中，仅支持载波带宽小于或等于20MHz的使用免许可频谱资源的信息传输。但随着宽带技术的演进，后续需要在免许可频谱资源上支持更大载波带宽(例如大于20MHz的载波带宽)的信息传输。因此，如何在免许可频谱资源上能够支持不同载波带宽的信息传输是本申请所要解决的技术问题。
发明内容
本申请实施例提供一种信息传输方法、终端设备及网络设备，不仅可以适用于不同带宽大小的信息传输，并且通过梳齿状的资源分配方式还可以提高信息的发射功率，进而提高信息的传输机会和传输性能。
第一方面，本申请实施例提供一种信息传输方法，该方法应用于包括网络设备和终端设备的通信系统，通信系统使用的载波上的第一带宽包括N1个第一资源块组RBG，至少两个第一RBG中的每个第一RBG中包括M1个频域资源连续的资源块RB，该方法包括：
终端设备接收网络设备发送的第一指示信息，第一指示信息用于指示终端设备从当前候选集合中确定目标梳齿组，当前候选集合包括第一候选集合；其中，第一候选集合包括至少两个第一梳齿组，第一梳齿组包括至少一个第一梳齿，第一梳齿包括至少两个第一RBG中的每个第一RBG中的一个RB，N1和M1均为自然数，且N1≥2，M1≥2；
终端设备根据第一指示信息从当前候选集合中确定目标梳齿组；
终端设备通过目标梳齿组向网络设备发送信息。
应理解的是，如果第一载波上的频谱有最大发射功率谱密度的限制，使用频域离散的资源分配方式，例如梳齿结构，可以有效提高信号的发射功率。
第一方面提供的信息传输方法应用于包括网络设备和终端设备的通信系统，通信系统使用的载波上的第一带宽包括N1个第一资源块组RBG，至少两个第一RBG中的每个第一RBG中包括M1个频域资源连续的资源块RB；终端设备通过接收网络设备发送的第一指示信息，第一指示信息用于指示终端设备从当前候选集合中确定目标梳齿组，当前候选集合包括第一候选集合，其中，第一候选集合包括至少两个第一梳齿组，第一梳齿组包括至少一个第一梳齿，第一梳齿包括至少两个第一RBG中的每个第一RBG中的一个RB；进一步地，终端设备根据第一指示信息从当前候选集合中确定目标梳齿组，并通过目标梳齿组向网络设备发送信息。可见，本申请实施例提供的信息传输方法不仅可以适用于不同带宽大小的信息传输，并且通过梳齿状的资源分配方式还可以提高信息的发射功率，进而提高信息的传输机会和传输性能。

具体实施方式
首先，对本申请实施例中所涉及的应用场景进行介绍。
本申请实施例可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)或第五代(5-Generation，5G)通信系统例如新一代无线技术(New Radio，或New RAT，NR)等。其中，当LTE系统在免许可频谱资源上传输时，可以认为是免许可长期演进(Unlicensed Long Term Evolution，U-LTE)系统(泛指所有使用免许可频谱的LTE系统)；U-LTE系统包括：许可辅助接入LTE(Licensed-Assisted Access Using LTE，LAA-LTE)系统及其演进系统(其中，免许可频谱资源上的载波的传输以许可频谱资源上的载波为辅助)、独立LTE(Stand-alone Long Term Evolution，SA-LTE)系统及其演进系统(其中，免许可频谱资源上的载波的传输没有许可频谱资源上的载波作为辅助)。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信。
图1为本申请实施例的无线通信系统的示意图。如图1所示，该通信系统100包括网络设备102，网络设备102可包括1个天线或多个天线例如，天线104、106、108、110、112和114。另外，网络设备102可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、 复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络设备102可以与类似于终端设备116或终端设备122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路(也称为下行链路)118向终端设备116发送信息，并通过反向链路(也称为上行链路)120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(Frequency Division Duplex，FDD)系统中，例如，前向链路118可与反向链路120使用不同的频带，前向链路124可与反向链路126使用不同的频带。
再例如，在时分双工(Time Division Duplex，TDD)系统和全双工(Full Duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。网络设备可以通过单个天线或多天线发射分集向其对应的扇区内所有的终端设备发送信号。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中，网络设备102的发射天线也可利用波束成形来改善前向链路118和124的信噪比。此外，与网络设备通过单个天线或多天线发射分集向它所有的终端设备发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
在本申请实施例中，该通信系统100所使用的资源可以包括调度资源，也可以包括免调度资源，或者说，在本申请实施例中，通信系统100中的各通信设备(例如，网络设备或终端设备)可以基于免调度传输方案使用资源进行通信，也可以基于调度方式使用资源进行通信，本申请实施例并未特别限定。作为示例而非限定，当各通信设备基于免调度传输方案使用资源进行通信时，该资源分配方式可以是预定义的，或者是网络设备半静态配置的。
其中，调度传输可以包括：网络设备传输下行信息所使用的资源需要由网络设备分配并通知给终端设备；或者，终端设备传输上行信息所使用的资源需要由网络设备 分配并通知给该终端设备。
需要说明的是，用于上行信息或下行信息传输的时间单元的长度可以为1ms，也可以小于1ms，还可以大于1ms，本申请对此并不限定。其中，上行信息可以包括上行数据信息，上行控制信息和上行随机接入序列等中的至少一种。上行信息可以通过物理上行共享信道(physical uplink shared channel，PUSCH)，物理上行控制信道(physical uplink control channel，PUCCH)，物理随机接入信道(physical random access channel，PRACH)，或是标准中新引入的功能相同、但名称不同的信道等进行传输。下行信息可以包括下行数据信息，下行控制信息和下行广播信息等中的至少一种。下行信息可以通过物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，物理下行控制信道(Physical Downlink Control Channel，PDCCH)，物理控制格式指示信道(Physical Control Format Indicator Channel，PCFICH)，物理混合重传指示信道(Physical hybrid ARQ indicator channel，PHICH)，增强物理下行控制信道(Enhanced-Physical Downlink Control Channel，EPDCCH)，物理广播信道(Physical Broadcast Channel，PBCH)，或是标准中新引入的功能相同、但名称不同的信道等进行传输。
在本申请实施例中，信息传输可以是上行信息传输，也可以是下行信息传输。不失一般性地，本申请实施例中以上行信息传输为例进行说明。
其次，对本申请所涉及的部分相关词汇进行解释说明。

还应理解，本申请实施例中的编号“第一”、“第二”仅仅为了区分不同的对象，例如为了区分不同的频域资源或不同的预设值，不应对根据本申请实施例的方法构成任何限定。
还应理解，在本申请中，“当…时”、“若”以及“如果”均指在某种客观情况下UE或者基站会做出相应的处理，并非是限定时间，且也不要求UE或基站实现时一定要有判断的动作，也不意味着存在其它限定。
本申请实施例结合终端设备描述了各个实施例。终端设备也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(Wireless Local Area Networks，WLAN)中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，简称“PDA”)设备、具有无线通信功能的手持设备、计算设备或连接到 无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统，例如，第五代通信(fifth-generation，5G)网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。

此外，本申请实施例结合网络设备描述了各个实施例。网络设备可以是网络设备等用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(ACCESS POINT，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)、宏基站、微基站(也称为“小基站”)、微微基站、接入站点(Access Point，AP)、传输站点(Transmission Point，TP)、或者未来5G NR网络中的网络设备或者未来演进的PLMN网络中的网络设备等；本申请实施例中对此并不作限制。
此外，LTE系统或NR系统中的载波上可以同时有多个小区同频工作，在某些特殊场景下，也可以认为系统中的载波与小区的概念等同。例如在载波聚合(Carrier Aggregation，CA)场景下，当为UE配置辅载波时，会同时携带辅载波的载波索引和工作在该辅载波的辅小区的小区标识(Cell Indentify，Cell ID)，在这种情况下，可以认为载波与小区的概念等同，比如UE接入一个载波和接入一个小区是等同的。

下面将结合本发申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
图2为本申请的信息传输方法实施例的流程示意图。如图2所示，本实施例的方法可以包括：
步骤S201、网络设备向终端设备发送第一指示信息，第一指示信息用于指示终端设备从当前候选集合中确定目标梳齿组，当前候选集合包括第一候选集合。
本申请的信息传输方法可应用于包括网络设备和终端设备的通信系统，该通信系统使用的载波上的第一带宽包括N1个第一资源块组RBG，该第一带宽中的至少两个所述第一RBG中的每个第一RBG中包括M1个频域资源连续的资源块RB，N1和M1均为自然数，且N1≥2，M1≥2。
需要说明的是，该通信系统使用的载波(为便于描述，记为：第一载波)可以为许可频谱上的载波，也可以为免许可频谱上的载波，本申请对此并不限定。
还需要说明的是，一定带宽(例如，第一载波上的第一带宽或第一载波上的系统带宽等)上的频域资源可以划分为多个资源块(Resource Block，RB)，其中，一个RB在频域上包括12个子载波。多个RB可以组成资源块组(Resource Block Group，RBG)，例如，一个RBG可以包括至少2个频域资源连续的RB。
还需要说明的是，第一载波可以用于上行传输，也可以用于下行传输，还可以在一段时间内用于上行传输，在另一段时间内用于下行传输，或者该第一载波中的一部分频谱用于上行传输，另一部分频谱用于下行传输等，本申请对此并不限定。
本实施例中的信息可以通过上行信道或下行信道传输。不失一般性，本申请以上行信道传输，即，终端设备向网络设备发送信息为例对本申请的实施方式进行说明。
可选地，第一载波的系统带宽大于20MHz。作为示例而非限定，第一载波的系统带宽为40M，80M，100M，200M，或400M中的一种。
可选地，第一带宽是第一载波的系统带宽。
可选地，第一带宽是网络设备在第一载波上为终端设备配置的带宽。例如，网络设备可以根据终端设备的射频能力，为终端设备在第一载波上配置不超过其射频能力的带宽，该带宽即为第一带宽。
可选地，第一带宽的大小小于或等于第一载波的系统带宽。
可选地，第一带宽大于或等于20MHz。
可选地，上行信息或下行信息对应的一个传输块可以使用第一带宽中的全部或部分频域资源进行传输。
可以理解的是，当第一带宽一定时，该第一带宽包括的RB的个数和该系统用于信号传输的子载波间隔的大小有关。当带宽和子载波间隔一定的情况下，该带宽包括的RB的个数是一定的。当子载波间隔一定的情况下，如果带宽大小不同，不同带宽包括的RB个数不同。当带宽一定的情况下，如果子载波间隔大小不同，该带宽包括的RB个数也不同。
作为示例而非限定，表1中给出了不同子载波间隔下不同带宽对应的RB个数。其中，表中的NA表示对应场景不支持。需要说明的是，表1中还考虑了射频RF边带的影响，即，对于某个带宽(例如第一带宽或第一载波的系统带宽)，需要在该带宽两侧 预留一定的频域资源不用于信息传输，以防止本系统的信号对相邻频带上的非本系统信号传输的干扰，或防止本系统中由于滤波器滚降设计原因引起的信息损失。以20MHz带宽，60kHz子载波间隔为例，用于传输信号的RB个数是24个，即，用于传输信号的频域资源大小为24(RB)*12(子载波/RB)*60(kHz/子载波)＝17280(kHz)＝17.28(MHz)。其中2.72(20-17.28)MHz可以作为该带宽预留的资源不用于信号传输。可选地，该带宽两侧预留的资源的大小相同，例如，该带宽两侧每侧各预留1.36MHz。可选地，该带宽两侧预留的资源的大小不同，例如，该带宽的一侧预留1.44MHz(2个RB)，另一侧预留1.28MHz。
表1不同子载波间隔下不同带宽对应的RB个数
Figure PCTCN2018108995-appb-000001
可选地，本申请实施例中，资源块组RBG为一定的子载波间隔下，由至少两个频域资源连续的RB组成。可选地，不同的RBG包括的频域资源连续的RB的个数不同。例如，第一RBG包括M1个频域资源连续的RB，第二RBG包括M2个频域资源连续的RB，其中，M1和M2不相同。可选地，不同的RBG对应的子载波间隔不同。例如，第一RBG包括M1个频域资源连续的RB，第二RBG包括M2个频域资源连续的RB，其中，M1和M2相同，但第一RBG对应的子载波间隔和第二RBG对应的子载波间隔不同。可选地，不同的RBG包括的频域资源连续的RB的个数和对应的子载波间隔均不同。例如，第一RBG包括M1个频域资源连续的RB，第二RBG包括M2个频域资源连续的RB，其中，M1和M2不相同，且第一RBG对应的子载波间隔和第二RBG对应的子载波间隔也不相同。
可选地，第一载波上的频域资源为基于竞争机制使用的频域资源，例如，免许可频谱上的资源。可选地，网络设备或终端设备在第一带宽上发送信号前，需要通过对该第一带宽所在的第一载波的信道进行检测，当判断该信道为空闲时，才能进行信号发送。应理解，该信道检测的方法可以和现有技术中免许可频谱上的信道检测方法可以相同或相似，此处不再赘述。
可选地，网络设备向终端设备发送第一指示信息之前，可以为终端设备配置该终端设备可以使用的第一载波上的第一带宽。其中，第一带宽的大小可以小于或等于第一载波的系统带宽的大小。可选地，网络设备可以通过物理层信令或高层信令指示终端设备在第一载波上的第一带宽的大小和/或位置。
可选地，第一指示信息用于指示终端设备从当前候选集合中确定目标梳齿组，其中，该目标梳齿组是网络设备为终端设备分配的第一载波上的频域资源。
需要说明的是，本申请实施例主要考虑频域上的资源分配，对于时间上资源，可以是一个或多个符号，也可以是一个或多个时隙，也可以是一个或多个TTI等，本申请对此并不限定。
可选地，当前候选集合仅包括第一候选集合。
可选地，当前候选集合除包括第一候选集合外，还包括其他的候选集合。进一步可选地，网络设备通过高层信令来配置当前候选集合为第一候选集合或者其他的候选集合。可选地，第一指示信息还用于指示当前候选集合为第一候选集合或者其他的候选集合。
可选地，网络设备向终端设备发送第一指示信息(该第一指示信息用于指示该终端设备从当前候选集合中确定目标梳齿组)，以便该终端设备根据该第一指示信息确定该网络设备为其所分配的目标梳齿组。可选地，第一指示信息可以为物理层信令或高层信令。可选地，第一指示信息可以为网络设备在接收到终端设备发送的请求资源信令(例如调度请求)之后发送的上行授权，或者可以为网络设备预先为终端设备配置的资源分配信息，例如通过无线资源控制(Radio Resource Control，RRC)信令发送；当然第一指示信息还可以为其它形式的信令，本申请实施例中对此并不作限制。
可选地，第一指示信息指示目标梳齿组的方式可以采用如下任一种方式：指示目标梳齿组包括的RB的标号(或索引)、或者目标梳齿组中梳齿的标号(或索引)、或者目标梳齿组所包括的频域资源所满足的分配规则等。
步骤S202、终端设备接收网络设备发送的所述第一指示信息，并根据所述第一指示信息从所述当前候选集合中确定所述目标梳齿组。
可以理解的是，当第一载波上的频域资源为免许可频谱上的资源时，需要遵从免许可频谱上的使用规范。例如，为了避免对其他使用免许可频谱资源的系统造成强干扰，通常会对使用免许可频谱资源的终端设备的最大发射功率或最大发射功率谱密度进行限制。例如，欧洲法规定义的不同频带上的信号发射功率/功率谱密度，如下表2所示。其中，EIRP表示等效全向辐射功率(Equivalent Isotropically Radiated Power，EIRP)，TPC表示发送功率控制(Transmit Power Control，TPC)。射频输出功率为一次传输机会中的平均EIRP。
表2、射频输出的平均EIRP上限和平均EIRP密度上限表
Figure PCTCN2018108995-appb-000002
根据上述描述，在免许可频谱资源上，终端设备的最大发射功率不能超过上述表2中定义的平均EIRP上限和平均EIRP密度上限中的最小值。需要说明的是，平均EIRP密度是以一个基本频域单元，例如1MHz，定义的，即只要每1MHz内传输的信号的功率不超过平均EIRP密度上限即可，对于每1MHz内实际传输的信号占用的带宽并不限定。由于免许可频谱上的最大发射功率谱密度限制，使用频域离散的资源可以有效提高信号的发射功率。因此，在免许可频谱上的资源分配中，可采用离散的资源分配方式，例如梳齿结构，来分配资源。
可选地，第一带宽包括N1个第一资源块组RBG，该第一带宽中的至少两个第一RBG中的每个第一RBG中包括M1个频域资源连续的资源块RB，N1和M1均为自然数，且N1≥2，M1≥2。
其中，第一梳齿包括该第一带宽中的至少两个第一RBG中的每个第一RBG中的一个RB。可选地，第一梳齿包括该第一带宽中的N1个第一RBG中的每个第一RBG中的一个RB。可选地，第一带宽包括M1个第一梳齿，该M1个第一梳齿中的每个第一梳齿包括该第一带宽中的N1个第一RBG中的每个第一RBG中的一个RB。
需要说明的是，在上行传输中，由于终端设备的能力有限，且发射功率受限，采用OFDM传输技术，发送信号具有非常高的峰值平均功率比(Peak to Average Power Ratio，PAPR)，从而增加模数转换和数模转换的复杂度，降低射频功率放大器的效率。因此，可以考虑单载波传输技术，即，时域信号包络符合单载波特性的传输技术，从而可以获得较低的PAPR或立方量度(Cubic Metric，CM)。例如，当采用集中式的资源用于信号传输时，在发送信号前可以对信号先做离散傅里叶变换(Discrete Fourier Transform，DFT)，再做快速傅里叶逆变换(Inverse Fast Fourier Transform，IFFT)，使信号具有单载波的特性，从而使系统的PAPR或CM较低。单载波传输也可以基于分布式的资源，例如，当采用频域等间隔离散的资源(例如，频域子载波等间隔离散排列的资源，或者RB等间隔离散排列的资源)进行信号传输时，通过对信号先做DFT，再做IFFT的方式，也可以降低信号传输的PAPR或CM。因此，在本申请实施例中，基于梳齿结构分配频域等间隔离散的资源，也可以降低信号传输的PAPR或CM。
可选地，第一梳齿包括该第一带宽中的至少两个第一RBG中的每个第一RBG中的一个RB，其中，该第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。
可选地，第一梳齿包括该第一带宽中的N1个第一RBG中的每个第一RBG中的一个RB，其中，该第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。
可选地，第一带宽包括M1个第一梳齿，该M1个第一梳齿中的每个第一梳齿包括该第一带宽中的N1个第一RBG中的每个第一RBG中的一个RB，其中，第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。

需要说明的是，第一梳齿中的每个RB可以分别为一个第一RBG中的一个RB(例如，当第一带宽刚好可以被划分为整数个第一RBG时)；第一梳齿也可以包括第一带宽中不属于任意一个第一RBG的RB(例如，当第一带宽不能被划分为整数个第一RBG时)，本申请对此并不限定。例如，如图3所示，第一梳齿#0包括N1个第一RBG中的每个第一RBG中的第1个RB，且第一梳齿#0还包括第一带宽中不属于任意一个第一RBG的RB#(N1*M1)。又例如，如图所示，第一梳齿#2包括N1个第一RBG中的每个第一RBG中的第3个RB。

可选地，一个第一梳齿组对应一个资源分配图案。例如，如图3所示，假设一个第一梳齿组可以包括M1个第一梳齿中的2个第一梳齿，该2个第一梳齿的标号为第一梳齿#0和第一梳齿#2，则该第一梳齿组对应的资源分配图案包括的RB的索引为：0、2、M1、M1+2、…，(N1-1)*M1、(N1-1)*M1+2、N1*M1。

作为示例而非限定，图5为本申请提供的第一带宽中的第一梳齿的结构示意图三，如图5所示，第一带宽包括107个RB，该107个RB包括10(即N1＝10)个第一RBG，该10个第一RBG中的每个第一RBG中包括10(即M1＝10)个频域资源连续的RB，该第一带宽包括的第11个RBG中包括7个频域资源连续的RB，即第11个RBG不是第一RBG。第一带宽包括10个第一梳齿，其中，一个第一梳齿包括该10个第一RBG中的每个第一RBG中的一个RB。特别地，每个第一梳齿包括的位于一个第一RBG中的一个RB在该第一RBG中的位置相同，即任意一个第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。可选地，第一梳齿还可以包括第11个RBG中的一个RB，即第一梳齿包括10个或11个RB。例如，索引为0～6的第一梳齿包括11个RB，索引为7～9的第一梳齿包括10个RB。具体地，索引为0的第一梳齿包括11个RB，对应索引为：0、10、20、30、40、50、60、70、80、90和100，索引为7的第一梳齿包括10个RB，对应索引为：7、17、27、37、47、57、67、77、87和97。一个第一梳齿组包括至少一个第一梳齿，第一候选集合包括至少两个第一梳齿组。可选地，当一个第一梳齿组包括的第一梳齿的个数大于1小于10时，该第一梳齿组包括的第一梳齿的标号可以不连续，例如一个第一梳齿组包括索引为0、2、4、6和8的第一梳齿；该第一梳齿组包括的第一梳齿的标号可以连续，例如一个第一梳齿组包括索引为1、2、3和4的第一梳齿。可选地，第一候选集合包括的第一梳齿组的个数大于或等于M1*(M1+1)/2＝10*11/2＝55。可选地，一个第一梳齿组对应一个资源分配图案。例如，一个第一梳齿组包括索引为0和5的第一梳齿，该第一梳齿组对应的资源分配图案包括的RB的索引为：0、5、10、15、20、25、30、35、40、45、50、55、60、65、70、75、80、85、90、95、100、105。
作为示例而非限定，图6为本申请提供的第一带宽中的第一梳齿的结构示意图四，如图6所示，第一带宽包括106个RB，该106个RB包括20(即N1＝20)个第一RBG，该20个第一RBG中的每个第一RBG中包括5(即M1＝5)个频域资源连续的RB，该第一带宽还包括6个RB，该6个RB不属于第一RBG。第一带宽包括5个第一梳齿，其中，一个第一梳齿包括该20个第一RBG中的每个第一RBG中的一个RB。特别地，每个第一梳齿包括的位于一个第一RBG中的一个RB在该第一RBG中的位置相同。可选地，第一梳齿仅包括位于第一RBG中的RB。例如，如图6中的情况1所示，索引为0的第一梳齿包括20个RB，对应索引为：0、5、10、15、20、25、30、35、40、45、56、61、66、71、76、81、86、91、96和101。可选地，第一梳齿除了包括位于第一RBG中的RB，还包括不属于第一RBG中的RB。例如，如图6中的情况2所示，索引为0的第一梳齿包括22 个RB，对应索引为：0、5、10、15、20、25、30、35、40、45、50、55、56、61、66、71、76、81、86、91、96和101。一个第一梳齿组包括至少一个第一梳齿，第一候选集合包括至少两个第一梳齿组。可选地，当一个第一梳齿组包括的第一梳齿的个数大于1小于5时，该第一梳齿组包括的第一梳齿的标号可以不连续，例如一个第一梳齿组包括索引为0和2的第一梳齿；该第一梳齿组包括的第一梳齿的标号可以连续，例如一个第一梳齿组包括索引为1、2、3和4的第一梳齿。可选地，第一候选集合包括的第一梳齿组的个数大于或等于M1*(M1+1)/2＝5*6/2＝15。可选地，一个第一梳齿组对应一个资源分配图案。例如，情况1中，一个第一梳齿组包括索引为0的第一梳齿，该第一梳齿组对应的资源分配图案包括的RB的索引为：0、5、10、15、20、25、30、35、40、45、56、61、66、71、76、81、86、91、96和101。
如前所述，为了避免对其他同时使用免许可频谱资源的系统造成强干扰，通常会对使用免许可频谱资源的终端设备的最大发射功率或最大发射功率谱密度进行限制。即在免许可频谱资源上，终端设备的最大发射功率不能超过上述表2中定义的平均EIRP上限和平均EIRP密度上限中的最小值。需要说明的是，平均EIRP密度是以1MHz为一个基本频域单元定义的，即只要每1MHz内传输的信号的功率不超过平均EIRP密度上限即可，对于每1MHz内实际传输的信号占用的带宽并不限定。因此，当通信设备用于进行通信传输的频率资源较少时，使用非连续的频域资源可以增加信号的输出功率，从而提高信号的传输性能。例如，在5150MHz到5350MHz这个频段中，对于一个具有TPC功能的通信设备，当该通信设备使用该频段的1MHz频域资源进行通信传输时，如果该1MHz频域资源为非连续的2个500kHz频域资源组成，且该2个500kHz频域资源在频域上的间隔大于1MHz，那么该2个500kHz频域资源中的每个500kHz频域资源可以使用的平均EIRP为10dBm，该通信设备使用该非连续资源传输该1MHz的信号使用的平均EIRP为13dBm，大于该频段上使用1MHz连续频域资源传输时可使用的平均EIRP上限10dBm，从而增加了信号的输出功率。当然需要注意，在该频段上传输的信号的平均EIRP上限为23dBm，假设同时满足平均EIRP上限为23dBm和平均EIRP密度上限为10dBm/MHz的要求，将该23dBm以10dBm/MHz的功率谱密度进行分配，可以支持20MHz带宽的信号传输。因此，可以以设备使用平均EIRP密度上限进行信号发送时可以支持的最大发送带宽为门限，将第一候选集合中的资源分配图案划分为两个子集合，当资源分配图案对应的带宽小于该最大发送带宽时，使用非连续资源进行信号传输可以进一步获得增加信号输出功率的效果。
可选地，第一候选集合包括第一候选子集合和第二候选子集合，第一候选子集合中包括的每个第一梳齿组所占的频域资源的大小均大于或等于第一预设值，第二候选子集合中包括的每个第一梳齿组所占的频域资源的大小均小于第一预设值。
可选地，该第一预设值X满足如下关系：Pmax＝P1+10*lgX，其中Pmax为终端设备的最大发送功率，P1为该终端设备在一个基本频域单元(例如，1MHz)内允许发送的最大发送功率(即最大发射功率谱密度)，lgX表示以10为底X的对数，X为频域资源大小。例如，Pmax为23dBm，P1为10dBm/MHz，那么该第一预设值X为20MHz。又例如，Pmax为40dBm，P1为13dBm/MHz，那么该第一预设值X为512MHz。又例如，Pmax为30dBm，P1为10dBm/MHz，那么该第一预设值X为100MHz。
可选地，第一预设值可以是通信系统规定的，或者，第一预设值可以是网络设备预先指示的，本申请对此并不限定。
可选地，该第一预设值的大小根据该第一载波所在频段的最大发射功率和最大发射功率谱密度来确定。作为示例而非限定，如上所述，在5150MHz到5350MHz这个频段中，对于一个具有TPC功能的通信设备，最大发射功率为23dBm，最大发射功率谱密度为10dBm/MHz，通信设备可以以10dBm/MHz的发射功率谱密度发送的最大信道带宽为20MHz，因此，该第一预设值为20MHz。作为示例而非限定，在57GHz到66GHz这个频段中，对于一个通信设备，最大发射功率为40dBm，最大发射功率谱密度为13dBm/MHz，通信设备可以以13dBm/MHz的发射功率谱密度发送的最大信道带宽为512MHz，因此，该第一预设值为512MHz。
可选地，该第一预设值为预设的频域资源的大小，或者，该第一预设值为K个梳齿，K为正整数，其中，该K个梳齿对应的频域资源为大于或等于预设的频域资源的最小值(即，该K个梳齿对应的频域资源大于或等于预设的频域资源，该K-1个梳齿对应的频域资源小于预设的频域资源)。可以理解的是，不同的梳齿结构，例如，不同的子载波间隔，或者不同的N1取值，或者不同的M1取值下，K的取值可以不同。
可选地，该第一预设值为2个梳齿，其中，在1个梳齿占用的频域资源上可以使用该频段上的最大发射功率。
可选地，该第一预设值为预设的频域资源的大小，或者，该第一预设值为K个RB，K为正整数，其中，该K个RB对应的频域资源为大于或等于预设的频域资源的最小值(即，该K个RB对应的频域资源大于或等于预设的频域资源，该K-1个RB对应的频域资源小于预设的频域资源)。可以理解的是，不同的子载波间隔下，K的取值可以不同。例如，假设该预设的频域资源的大小为20MHz，该第一预设值为K个RB，那么K个RB对应的频域资源为大于或等于20MHz的最小值。
可选地，该第一预设值的大小根据该第一载波所在频段来确定，或者，预设的频域资源的大小根据该第一载波所在频段来确定。作为示例而非限定，当该第一载波所在频段为5GHz左右的频段时，该第一预设值或预设的频域资源的大小为20MHz。作为示例而非限定，当该第一载波所在频段为60GHz左右的频段时，该第一预设值或预设的频域资源的大小为512MHz。
作为示例而非限定，预设的频域资源的大小为20MHz，当子载波间隔是15kHz时，第一预设值为112个RB；当子载波间隔是30kHz时，第一预设值为56个RB；当子载波间隔是60kHz时，第一预设值为28个RB；当子载波间隔是120kHz时，第一预设值为14个RB。
作为示例而非限定，预设的频域资源的大小为512MHz，当子载波间隔是60kHz时，第一预设值为712个RB；当子载波间隔是120kHz时，第一预设值为356个RB；当子载波间隔是240kHz时，第一预设值为178个RB；当子载波间隔是480kHz时，第一预设值为89个RB。
作为示例而非限定，用于资源分配的一个第一梳齿的结构如图4所示，一个第一梳齿包括10个RB。假设预设的频域资源大小为20MHz。如果第一梳齿的子载波间隔是60kHz，一个第一梳齿对应的频域资源的大小为7.2MHz，3个第一梳齿对应的带宽大于 20MHz，2个第一梳齿对应的带宽小于20MHz，因此，K等于3(或者第一预设值等于3个第一梳齿)；如果第一梳齿的子载波间隔是30kHz，一个第一梳齿对应的频域资源的大小为3.6MHz，6个第一梳齿对应的带宽大于20MHz，5个第一梳齿对应的带宽小于20MHz，因此，K等于6(或者第一预设值等于6个第一梳齿)。
如前所述，当资源分配图案对应的带宽小于设备使用平均EIRP密度上限进行信号发送时可以支持的最大发送带宽(例如，第一预设值)时，使用非连续资源进行信号传输可以进一步获得增加信号输出功率的效果。由于第二候选子集合中包括的每个第一梳齿组所占的频域资源的大小均小于第一预设值，当第一预设值对应的频域资源大于2个第一梳齿占用的频域资源且第二候选子集合中的第一梳齿组包括的第一梳齿的个数大于或等于2时，对于第二候选子集合中包括的第一梳齿组，使用2个频域资源离散的第一梳齿相比于使用2个连续的第一梳齿仍然可以获得增加发射功率的好处。需要说明的是，这里连续的2个第一梳齿，指的是该2个第一梳齿在同一个第一RBG中占用的2个RB为连续的RB。
可选地，为了满足规定的频谱资源占用率要求，第一候选集合中的至少一个第一梳齿组占用的频域资源在频域上的最大频域间隔大于或等于第二预设值。其中，第一梳齿组占用的频域资源在频域上的最大频域间隔是指：该第一梳齿组在频域上占用的第一个RB与最后一个RB之间的频域间隔，或者该第一梳齿组在频域上占用的第一个子载波与最后一个子载波之间的频域间隔。可选地，该第二预设值可以为第一带宽或第一载波的系统带宽的80％或70％(例如，5G频段中第二预设值可以为80％，6G频段中第二预设值可以为70％)；当然也可等于其它数值，本申请实施例中对此并不作限制。可选地，第二预设值可以是通信系统规定的，或者，第二预设值可以是网络设备预先指示的，本申请对此并不限定。可选地，通信系统中不显示规定或指示该第二预设值，但第一候选集合中的第一梳齿组满足该特征。
可选地，第二候选子集合中的至少一个第一梳齿组包括P个第一梳齿，P个第一梳齿占用N1个第一RBG中的至少两个第一RBG中的每个第一RBG中的P个RB，其中，P个RB中的至少两个RB在频域上非连续，P为自然数，且2≤P＜M1。
可选地，第一预设值为K个第一梳齿，K为正整数，K>2，因此P的取值范围为2≤P＜K。如前所述，当信号占用的频域资源小于第一预设值时，对于不同的第一梳齿间，使用非连续资源传输信号可以进一步使信号的发射功率增强。因此，第二候选子集合中的至少一个第一梳齿组包括P个第一梳齿，该P个第一梳齿在一个第一RBG中占用的P个RB中的至少两个RB在频域上非连续。
需要说明的是，在本申请实施例中，一个第一梳齿组包括至少两个非连续的第一梳齿，可以认为是：该第一梳齿组包括的至少两个第一梳齿在第一带宽包括的N1个第一RBG中的至少两个第一RBG中的每个第一RBG中占用的RB中的至少两个RB在频域上非连续。一个第一梳齿组包括连续的第一梳齿，可以认为是：该第一梳齿组包括的至少一个第一梳齿在第一带宽包括的N1个第一RBG中的至少两个第一RBG中的每个第一RBG中占用连续的RB。
可选地，第一预设值为K个RB，K为正整数，P个第一梳齿占用的RB个数小于K，且该P个第一梳齿在一个第一RBG中占用的P个RB中的至少两个RB在频域上非连续。
以图3所示的第一梳齿的结构示意图为例进行说明。第一带宽包括M1个第一梳齿，第一预设值为K个第一梳齿，2＜K＜M1，第二候选子集合中的一个第一梳齿组包括P个第一梳齿，2≤P＜K，该P个第一梳齿在一个第一RBG中占用的P个RB中的至少两个RB在频域上非连续。例如，第二候选子集合中的一个第一梳齿组包括2(P＝2)个第一梳齿，该2个第一梳齿分别为第一梳齿#0和第一梳齿#2，第一梳齿#0和第一梳齿#2在同一个第一RBG中占用的RB非连续，例如，在第一RBG#0中，第一梳齿#0占用RB#0，第一梳齿#2占用RB#2。
可选地，该P个第一梳齿中至少两个第一梳齿的索引非连续，其中，该P个第一梳齿对应的频域资源在频域上是等间隔分布的。
可选地，该P个第一梳齿占用的RB在频域上是等间隔分布的。
下面对第二候选子集合中包括至少一个第一梳齿组，该第一梳齿组包括至少两个非连续的第一梳齿的情况进行举例说明。作为示例，假设第一预设值为20MHz，或者，第一预设值为K个RB，K为正整数。
如图4所示，第一带宽包括10个第一梳齿，标号分别为0～9，其中，每个第一梳齿包括10个RB，任意一个第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。
若子载波间隔为60kHz，则第一预设值为28个RB，或者，第一预设值为3个第一梳齿(因为2个第一梳齿占用的频域资源小于20MHz，3个第一梳齿占用的频域资源大于20MHz)。因此，第二候选子集合中包括至少一个第一梳齿组，该第一梳齿组包括2个第一梳齿，该2个第一梳齿的标号可以为0和5，或者1和6，或者2和7，或者3和8，或者4和9。
若子载波间隔为30kHz，则第一预设值为56个RB，或者，第一预设值为6个第一梳齿(因为5个第一梳齿占用的频域资源小于20MHz，6个第一梳齿占用的频域资源大于20MHz)。因此，第二候选子集合中包括的至少一个第一梳齿组，该第一梳齿组包括P个第一梳齿，2≤P＜6，其中，
P＝2时，该2个第一梳齿的标号可以为0和5，或者1和6，或者2和7，或者3和8，或者4和9；或者，
P＝3时，该3个第一梳齿的标号可以为0、3、6，或者1、4、7，或者2、5、8，或者3、6、9，或者0、1、5，或者2、3、7，或者4、8、9；或者，
P＝4时，该4个第一梳齿的标号可以为0、1、5、6，或者3、4、8、9；或者，
P＝5时，该5个第一梳齿的标号可以为0、2、4、6、8，或者1、3、5、7、9。
图5所示的第一梳齿的结构和图4所示的第一梳齿的结构类似，区别在于一个第一梳齿可以包括10个或11个RB，因此，上述图4中的第二候选子集合包括的至少一个第一梳齿组包括至少两个非连续的第一梳齿的实施例也适用于图5，此处不再赘述。
对于图6所示的第一梳齿结构，第一带宽包括5个第一梳齿，标号分别为0～4，情况1中，每个第一梳齿包括20个RB，情况2中，每个第一梳齿包括21或22个RB。
若子载波间隔为60kHz，则第一预设值为28个RB，或者，第一预设值为2个第一梳齿(因为1个第一梳齿占用的频域资源小于20MHz，2个第一梳齿占用的频域资源大于20MHz)。由于第二候选子集合中包括的每个第一梳齿组所占的频域资源的大小均小 于第一预设值，因此第二候选子集合中包括的每个第一梳齿组均包括一个第一梳齿组，即，第二候选子集合中不包括占用两个或两个以上第一梳齿的第一梳齿组。
若子载波间隔为30kHz，则第一预设值为56个RB，或者，第一预设值为3个第一梳齿(因为2个第一梳齿占用的频域资源小于20MHz，3个第一梳齿占用的频域资源大于20MHz)。可选地，第二候选子集合中包括至少一个第一梳齿组，该第一梳齿组包括2个第一梳齿，该2个第一梳齿的标号可以为0和2，或者0和3，或者1和3，或者1和4，或者2和4。从另外一方面来说，考虑到该情况下一个第一梳齿包括20个RB，且该20个RB中相邻两个RB之间的最小距离为5个RB(即1.8MHz)，该第一梳齿包括的20个RB中的每个RB都可以使用1M带宽上的最大发射功率，即一个第一梳齿就可以使用20M频域资源上的最大发射功率，因此，可选地，第一预设值为2个第一梳齿，第二候选子集合中包括的每个第一梳齿组均包括一个第一梳齿组，即，第二候选子集合中不包括占用两个或两个以上第一梳齿的第一梳齿组。
可选地，在本申请实施例中，A和B之间的频域间隔是指：A占用的第一个RB与B占用的第一个RB之间的频域间隔，或者A占用的第一个子载波与B占用的第一个子载波之间的频域间隔。
可选地，该P个第一梳齿占用的RB在频域上的最小频域间隔大于或等于第三预设值。可选地，该最小频域间隔为该P个第一梳齿占用的RB在频域上不连续的RB间隔中的最小值。
以图3所示的第一梳齿的结构示意图为例进行说明。第一带宽包括M1个第一梳齿，第一预设值为K个第一梳齿，2＜K＜M1，第二候选子集合中的一个第一梳齿组包括P个第一梳齿，2≤P＜K，该P个第一梳齿在一个第一RBG中占用的P个RB中的至少两个RB在频域上非连续。例如，第二候选子集合中的一个第一梳齿组包括3(P＝3)个第一梳齿，该3个第一梳齿分别为第一梳齿#0，第一梳齿#2和第一梳齿#3，该3个第一梳齿占用的RB在频域上的最小频域间隔为2个RB(即一个第一RBG中第一梳齿#0和第一梳齿#2所占RB之间的间隔)。
可选地，该第三预设值为预设的频域资源的大小，或者，该第三预设值为X个RB，X为正整数，其中，该X个RB对应的频域资源为大于或等于预设的频域资源的最小值(例如，该X个RB对应的频域资源大于或等于预设的频域资源，该X-1个RB对应的频域资源小于预设的频域资源)。
可选地，所述第三预设值可以为1MHz，当然也可等于其它数值，本申请实施例中对此并不作限制。可选地，所述第三预设值可以是通信系统规定的，或者，所述第三预设值可以是网络设备预先指示的，本申请对此并不限定。
作为示例而非限定，假设第三预设值为1MHz，如图4所示，第一带宽包括10个第一梳齿，标号分别为0～9，其中，每个第一梳齿包括10个RB，任意一个第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。
以子载波间隔为30kHz为例，则第三预设值为3个RB，当第二候选子集合中的一个第一梳齿组包括P(P＝3)个第一梳齿，如果该3个第一梳齿占用的RB在频域上的最小频域间隔大于或等于第三预设值，该P个第一梳齿可以使用该频段上的最大发射功率。例如，该3个第一梳齿的标号分别为0、3、6，即该P个第一梳齿包括的RB为0、3、6、 10、13、16、20、23、26、30、33、36、40、43、46、50、53、56、60、63、66、70、73、76、80、83、86、90、93、96。可以看出，该P个第一梳齿占用的频域资源在频域上非连续的RB之间的间隔分别为3个RB和4个RB，即，该P个第一梳齿占用的频域资源在频域上的最小频域间隔为3个RB，等于第三预设值。因此，该3个第一梳齿可以使用该频段上的最大发射功率。
对于图5或图6等所示的第一梳齿的结构，上述以图4为例的实施例对应的原则也同样适用，此处不再赘述。
在本实现方式中，当信号占用的频域资源小于预设的频域资源时，通过分配频域非连续的资源，可以使信号传输时采用功率加强(power boosting)技术，提高信号输出功率。
可选地，第一候选子集合中包括的第一梳齿组在N1个第一RBG中的至少两个第一RBG中的每个第一RBG中占用频域资源连续的RB。
或者说，所述第一候选子集合中包括的第一梳齿组包括连续的第一梳齿。
可以理解的是，由于第一候选子集合中包括的每个第一梳齿组所占的频域资源的大小均大于或等于第一预设值，对于第一候选子集合中的第一梳齿组来说，使用连续的梳齿或使用非连续的梳齿，能获得的最大发射功率都是一样的。因此，为了减小无意义的资源分配图案，第一候选子集合中包括的第一梳齿组在同一个第一RBG中占用频域资源连续的RB。
以图3所示的第一梳齿的结构示意图为例进行说明。第一带宽包括M1个第一梳齿，第一预设值为K个第一梳齿，2＜K＜M1，第一候选子集合中的第一梳齿组包括K个或K个以上的第一梳齿，该K个或K个以上的第一梳齿在一个第一RBG中占用频域资源连续的K个或K个以上的RB。例如，第一候选子集合中的一个第一梳齿组包括K个第一梳齿，该K个第一梳齿在同一个第一RBG中占用的RB连续，例如，在第一RBG#0中，该K个第一梳齿占用RB#0，RB#1，RB#2，…，RB#(K-1)。
下面对第一候选子集合包括的第一梳齿组进行举例说明，作为示例，假设第一预设值为20MHz，或者，第一预设值为K个RB，K为正整数。
如图4所示，第一带宽包括10个第一梳齿，标号分别为0～9，其中，每个第一梳齿包括10个RB，任意一个第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。
若子载波间隔为60kHz，则第一预设值为28个RB，或者，第一预设值为3个第一梳齿(因为2个第一梳齿占用的频域资源小于20MHz，3个第一梳齿占用的频域资源大于20MHz)。因此，第一候选子集合中包括的第一梳齿组均包括至少3个第一梳齿，并且，该至少3个第一梳齿在同一个第一RBG中占用连续的RB。
若子载波间隔为30kHz，则第一预设值为56个RB，或者，第一预设值为6个第一梳齿(因为5个第一梳齿占用的频域资源小于20MHz，6个第一梳齿占用的频域资源大于20MHz)。因此，第一候选子集合中包括的第一梳齿组均包括至少6个第一梳齿，并且，该至少6个第一梳齿在同一个第一RBG中占用连续的RB。
图5所示的第一梳齿的结构和图4所示的第一梳齿的结构类似，区别在于一个第一梳齿可以包括10个或11个RB，因此，上述图4中的第一候选子集合包括的第一梳齿组 的实施例也适用于图5，此处不再赘述。
对于图6所示的第一梳齿结构，第一带宽包括5个第一梳齿，标号分别为0～4，情况1中，每个第一梳齿包括20个RB，情况2中，每个第一梳齿包括21或22个RB。
若子载波间隔为60kHz，则第一预设值为28个RB，或者，第一预设值为2个第一梳齿(因为1个第一梳齿占用的频域资源小于20MHz，2个第一梳齿占用的频域资源大于20MHz)。因此，第一候选子集合中包括的第一梳齿组均包括至少2个第一梳齿，并且，该至少2个第一梳齿在同一个第一RBG中占用频域资源连续的RB。
若子载波间隔为30kHz，可选地，第一预设值为56个RB，或者，第一预设值为3个第一梳齿(因为2个第一梳齿占用的频域资源小于20MHz，3个第一梳齿占用的频域资源大于20MHz)。因此，第一候选子集合中包括的第一梳齿组均包括至少3个第一梳齿，并且，该至少3个第一梳齿在同一个第一RBG中占用频域资源连续的RB。
若子载波间隔为30kHz，考虑到该情况下一个第一梳齿包括20个RB，且该20个RB中相邻两个RB之间的最小距离为5个RB(即1.8MHz)，该第一梳齿包括的20个RB中的每个RB都可以使用1M带宽上的最大发射功率，即一个第一梳齿就可以使用20M频域资源上的最大发射功率，因此，可选地，第一预设值为2个第一梳齿，第一候选子集合中包括的第一梳齿组均包括至少2个第一梳齿，并且，该至少2个第一梳齿在同一个第一RBG中占用频域资源连续的RB。
当目标梳齿组为第一候选子集合中的第一梳齿组时，在满足频域资源大于或等于第一预设值的情况下通过分配频域连续的多个梳齿，可以在不损失发射功率的情况下减小资源分配图案的个数。
需要说明的是，虽然当目标梳齿组大于或等于第一预设值时，分配频域连续的梳齿组是可选的资源分配方式，从系统的角度来看，由于网络设备可以采用分配频域非连续的梳齿组的方式对一个终端设备分配小于第一预设值的频域资源，当网络设备将系统中除了分配给该终端设备的频域资源外的其他频域资源分配给另一终端设备时，可以采用分配频域非连续的梳齿组的实现方式。
可选地，第一候选子集合中的至少一个第一梳齿组包括Q个第一梳齿，Q个第一梳齿占用N1个第一RBG中的至少两个第一RBG中的每个第一RBG中的Q个RB，Q个RB中的至少两个RB在频域上非连续，Q为自然数，且2≤Q＜M1，其中，第一带宽中除Q个第一梳齿占用的频域资源之外的频域资源大小小于第一预设值。
或者说，第一候选子集合中的至少一个第一梳齿组包括Q个第一梳齿，该Q个第一梳齿包括至少两个非连续的第一梳齿。
可选地，该Q个第一梳齿中至少两个第一梳齿的索引非连续，其中，该Q个第一梳齿对应的频域资源在频域上是等间隔分布的。
可选地，该Q个第一梳齿占用的RB在频域上是等间隔分布的。
可选地，第一预设值为K个第一梳齿，K为正整数，K≤Q。可选地，第一预设值为K个RB，K为正整数，Q个第一梳齿占用的RB个数大于或等于K。
可选地，第一带宽上包括第一梳齿组#1和第一梳齿组#2，其中，第一梳齿组#1是第一候选子集合中的一个第一梳齿组，第一梳齿组#1占用的频域资源大于或等于第一预设值，第一梳齿组#2是第二候选子集合中的一个第一梳齿组，第一梳齿组#2占用的 频域资源小于第一预设值，第一梳齿组#1和第一梳齿组#2占用的资源之和为第一带宽包括的所有资源。如前所述，为了增加信号的发射功率，第一梳齿组#2在一个第一RBG中占用的RB中的至少两个RB在频域上非连续，相应地，作为第一梳齿组#2的补集的第一梳齿组#1在一个第一RBG中占用的RB中的至少两个RB在频域上非连续。或者说，第一带宽中的资源包括第一梳齿组#1和第一梳齿组#2，第一梳齿组#2和第一梳齿组#1的资源之和为第一带宽包括的所有资源，由于第一梳齿组#2包括至少两个非连续的第一梳齿，第一梳齿组#1也包括至少两个非连续的第一梳齿。
以图3所示的第一梳齿的结构示意图为例进行说明。第一带宽包括M1个第一梳齿，第一预设值为K个第一梳齿，2＜K＜M1，第一候选子集合中的一个第一梳齿组#1包括Q个第一梳齿，K≤Q＜M1，第二候选子集合中的一个第一梳齿组#2包括P个第一梳齿，2≤P＜K，且，P+Q＝M1，即第一梳齿组#1和第一梳齿组#2占用的资源之和为第一带宽包括的所有资源。第一梳齿组#2包括的P个第一梳齿在一个第一RBG中占用的P个RB中的至少两个RB在频域上非连续，因此，第一梳齿组#1包括的Q个第一梳齿在一个第一RBG中占用的Q个RB中的至少两个RB在频域上非连续。例如，第一梳齿组#2包括2(P＝2)个第一梳齿，该2个第一梳齿分别为第一梳齿#0和第一梳齿#2，第一梳齿#0和第一梳齿#2在同一个第一RBG中占用的RB非连续，例如，在第一RBG#0中，第一梳齿#0占用RB#0，第一梳齿#2占用RB#2；相应地，第一梳齿组#1包括M1-2(其中，Q＝M1-P)个第一梳齿，该(M1-2)个第一梳齿分别为第一梳齿#1，第一梳齿#3至第一梳齿#(M1-1)。第一梳齿#1，第一梳齿#3至第一梳齿#(M1-1)在同一个第一RBG中占用的RB非连续，例如，在第一RBG#0中，第一梳齿组#1占用的RB为RB#1，RB#3至RB#(M1-1)。
下面对第一候选子集合中包括至少一个第一梳齿组，该第一梳齿组包括至少两个非连续的第一梳齿的情况进行举例说明。作为示例，假设第一预设值为20MHz，或者，第一预设值为K个RB，K为正整数。
如图4所示，第一带宽包括10个第一梳齿，标号分别为0～9，其中，每个第一梳齿包括10个RB，任意一个第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。
若子载波间隔为60kHz，则第一预设值为28个RB，或者，第一预设值为3个第一梳齿(因为2个第一梳齿占用的频域资源小于20MHz，3个第一梳齿占用的频域资源大于20MHz)。因此，若第二候选子集合中包括至少一个第一梳齿组#2，该第一梳齿组#2包括至少两个非连续的第一梳齿，那么作为补集，第一候选子集合中也应该包括至少一个第一梳齿组#1，该第一梳齿组#1包括至少两个非连续的第一梳齿。例如，第一梳齿组#2包括2个第一梳齿，该2个第一梳齿的标号为0和5，那么第一梳齿组#1包括8(其中，8＝10-2)个第一梳齿，该8个第一梳齿的标号为1、2、3、4、6、7、8和9。
若子载波间隔为30kHz，则第一预设值为56个RB，或者，第一预设值为6个第一梳齿(因为5个第一梳齿占用的频域资源小于20MHz，6个第一梳齿占用的频域资源大于20MHz)。因此，若第二候选子集合中包括的至少一个第一梳齿组#2，该第一梳齿组#2包括至少两个非连续的第一梳齿，那么作为补集，第一候选子集合中也应该包括至少一个第一梳齿组#1，该第一梳齿组#1包括至少两个非连续的第一梳齿。例如，该第一梳齿组#2包括P个第一梳齿，2≤P＜6，该第一梳齿组#1包括Q个第一梳齿，6≤Q＜ 10，其中，
P＝2时，Q＝8，第一梳齿组#2包括的2个第一梳齿的标号为0和5，第一梳齿组#1包括的8个第一梳齿的标号为1、2、3、4、6、7、8和9；或者，
P＝3时，Q＝7，第一梳齿组#2包括的3个第一梳齿的标号为0、3、6，第一梳齿组#1包括的7个第一梳齿的标号为1、2、4、5、7、8和9；或者，
P＝4时，Q＝6，第一梳齿组#2包括的4个第一梳齿的标号可以为0、1、5、6，第一梳齿组#1包括的6个第一梳齿的标号为2、3、4、7、8和9。
需要说明的是，当Q＝9时，第一梳齿组#1包括的Q个第一梳齿为连续的第一梳齿。
图5所示的第一梳齿的结构和图4所示的第一梳齿的结构类似，区别在于一个第一梳齿可以包括10个或11个RB，因此，上述图4中的第一候选子集合包括的至少一个第一梳齿组包括至少两个非连续的第一梳齿的实施例也适用于图5，此处不再赘述。
对于图6所示的第一梳齿结构，第一带宽包括5个第一梳齿，标号分别为0～4，情况1中，每个第一梳齿包括20个RB，情况2中，每个第一梳齿包括21或22个RB。
若子载波间隔为60kHz，则第一预设值为28个RB，或者，第一预设值为2个第一梳齿(因为1个第一梳齿占用的频域资源小于20MHz，2个第一梳齿占用的频域资源大于20MHz)。由于第二候选子集合中包括的每个第一梳齿组所占的频域资源的大小均小于第一预设值，因此第二候选子集合中包括的每个第一梳齿组均包括一个第一梳齿组，即，第二候选子集合中不包括占用两个或两个以上第一梳齿的第一梳齿组。相应地，第一候选子集合中包括的每个第一梳齿组均包括连续的第一梳齿。
若子载波间隔为30kHz，则第一预设值为56个RB，或者，第一预设值为3个第一梳齿(因为2个第一梳齿占用的频域资源小于20MHz，3个第一梳齿占用的频域资源大于20MHz)。可选地，第二候选子集合中包括至少一个第一梳齿组#2，该第一梳齿组#2包括2个非连续的第一梳齿，例如，该2个第一梳齿的标号为0和2，作为补集，第一候选子集合中也包括至少一个第一梳齿组#1，该第一梳齿组#1包括3个第一梳齿，且该第一梳齿组#1包括至少两个非连续的第一梳齿，例如，该3个第一梳齿的标号为1、3和4。从另外一方面来说，考虑到该情况下一个第一梳齿包括20个RB，且该20个RB中相邻两个RB之间的最小距离为5个RB(即1.8MHz)，该第一梳齿包括的20个RB中的每个RB都可以使用1M带宽上的最大发射功率，即一个第一梳齿就可以使用20M频域资源上的最大发射功率，因此，可选地，第一预设值为2个第一梳齿，第二候选子集合中包括的每个第一梳齿组均包括一个第一梳齿组，即，第二候选子集合中不包括占用两个或两个以上第一梳齿的第一梳齿组。相应地，第一候选子集合中包括的每个第一梳齿组均包括连续的第一梳齿。
可选地，系统频域资源包括M1个第一梳齿，第一预设值等于K个第一梳齿，当网络设备为目标终端设备分配Q个第一梳齿(即目标梳齿组)用于信号传输，由于所述网络设备将M1个第一梳齿中除该Q个第一梳齿之外的P(P同时满足2≤P≤(M1-K)和P＜K)个第一梳齿分配给其它至少一个终端设备，且该P个第一梳齿中至少两个第一梳齿的索引非连续(可选地，该P个第一梳齿对应的频域资源在频域上是等间隔分布的，或者，该P个第一梳齿中相邻两个第一梳齿的索引之间的间隔是相等的，或者，该P个第一梳齿对应的频域资源在频域上的最小频域间隔大于或等于第三预设值)，则该Q 个第一梳齿同时满足K≤Q＜M1、Q>floor(M1/2)和P+Q＝M1，并且，即使Q≥K(即所述Q个第一梳齿占用的频域资源大于或等于所述第一预设值)，该Q个第一梳齿中至少两个第一梳齿的索引必定也是非连续。
在本资源分配方式中，当信号占用的频域资源大于或等于预设的频域资源，且系统频域资源中的剩余频域资源包括至少两个索引非连续的第一梳齿时，通过分配频域非连续的资源，可以使系统在进行资源分配时更灵活有效地分配所有系统频域资源。
可选地，网络设备可以任意联合使用满足以上特征的第一梳齿组为终端设备分配频域资源，以增加系统分配资源的灵活性。作为示例而非限定，如图4或图5所示的第一带宽包括10个第一梳齿，标号分别为0～9，其中，任意一个第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等的梳齿结构为例对本申请实施例的信号传输方法进行说明。假设第一预设值为6个第一梳齿。例如，当网络设备为3个终端设备分配资源时，网络设备将索引编号为0、1、5和6的第一梳齿分配给终端设备1，将索引编号为2、3和7的第一梳齿分配给终端设备2，以及将索引编号为4、8和9的第一梳齿分配给终端设备3。又例如，当网络设备为4个终端设备分配资源时，网络设备将索引编号为0、3和6的第一梳齿分配给终端设备1，将索引编号为1、4和7的第一梳齿分配给终端设备2，将索引编号为2、5和8的第一梳齿分配给终端设备3，以及将索引编号为9的第一梳齿分配给终端设备4。
当然，网络设备也可以将系统频域资源上的资源分配给3个及以上数量个终端设备，具体的分配频域资源的方式可与上述类似，此处不再赘述。可见，通过互补分配方式，不仅可以增加系统分配资源的灵活性，可以提高被分配较少资源的终端设备的信号传输功率，还可以提高资源的利用率。
在本申请实施例中，第一带宽可以包括至少一个子带。可选地，第一带宽包括第一子带和第二子带。可选地，由于免许可频谱上的信道是以20MHz为单位进行划分的，第一子带或第二子带的大小为20MHz的整数倍。作为示例，图7为本申请提供的第一带宽包括两个子带时的结构示意图。
在图7的情况1中，第一带宽被划分为第一子带和第二子带，其中，第一子带和第二子带的大小可以相同，例如，第一子带和第二子带的大小均为20MHz，第一子带和第二子带的大小也可以不同，例如，第一子带的大小为40MHz，第二子带的大小为20MHz，情况1中并未限定。
在图7的情况2中，第一带宽包括第一子带和第二子带，其中，第一子带和第二子带至少有部分不重叠。例如，第一子带和第二子带的大小均为40MHz，其中，第一子带和第二子带重叠部分的大小为20MHz。

作为示例而非限定，图8为本申请提供的一个第一载波上的系统带宽包括至少一个子带的示意图。在图8中，子带带宽为20M，第一载波上的系统带宽可以为20MHz、40MHz、60MHz、80MHz或100MHz中的一种。第一载波包括的RB的个数是根据系统带宽的大小和一定的子载波间隔确定的。例如，以第一载波上的系统带宽为40MHz，子载波间隔为30kHz为例，对图8进行说明。如图8所示，第一载波上的系统频域资源包括2个子带，每个子带的大小相同，且每个子带包括整数个RB，例如每个子带包括50个RB。可选地，在两个子带中间包括4个RB，可选地，该4个RB是为了避免RF的影响预留的作为保护间隔的RB。其中，该4个RB可以用于信号传输，也可以不用于信号传输，本申请对此并不限定。
作为示例而非限定，图9为本申请提供的另一个第一载波上的系统带宽包括至少一个子带的示意图。在图9中，以第一载波上的系统带宽为80MHz进行举例说明。第一载波上的系统带宽内可以包括9个子带，其中，子带#0，#1，#2，#3的带宽分别为20MHz，子带#4，#5，#6的带宽分别为40MHz，子带#7和#8的带宽分别为60MHz。可选地，在任意一个子带的两边均预留一定的频域资源，用于避免RF的影响。其中，该预留的资源不用于信号传输。可以理解的是，对于一个子带的预留频域资源，可以是另外一个子带可用于信号传输的资源。例如，子带#1两侧预留的频域资源在子带#7中是可以正常使用的资源。
可选地，当子带是根据第一载波上的系统带宽进行划分的时，第一带宽可以包括第一载波上的至少一个子带。
可选地，终端设备根据第一指示信息从第一候选集合中确定目标梳齿组。其中，第一候选集合中包括的第一梳齿组的结构是根据第一带宽的大小确定的。
可选地，终端设备根据第一指示信息从第一候选集合中确定目标梳齿组。其中，第一候选集合中包括的第一梳齿组的结构是根据第一载波的系统带宽的大小确定的。作为示例而非限定，网络设备在为终端设备分配第一带宽上的频域资源时，通过第一指示信息指示第一候选集合中的第一梳齿组为目标梳齿组，终端设备根据第一指示信息确定目标梳齿组，并根据目标梳齿组和其被分配的第一带宽确定该目标梳齿组上的可用资源。可选地，第一带宽的大小或位置可以是通信系统规定的，或者是网络设备指示的，或者是根据网络设备和/或终端设备的射频能力确定的，本申请对此并不限定。
可选地，第一带宽包括第一子带，第一子带包括N1个第一RBG中频域资源连续的S1个第一RBG，S1为自然数，且2≤S1＜N1。

作为示例而非限定，以图9为例，对第一候选集合中的第一候选子集合、第二候选子集合和第三候选子集合进行说明。假设第一载波上的系统带宽为80MHz，且第一带宽等于第一载波上的系统带宽，即，第一带宽也为80MHz，第一子带为子带#6，第一子带的带宽为40MHz，子载波间隔为60kHz，第一预设值为20MHz。第一带宽包括111个RB，标号为从0到110，其中，第一带宽两侧各预留2个RB用于避免RF影响，即第一带宽的有效频域资源部分包括107个RB，标号为从2到108。该107个RB包括10(即N1＝10)个第一RBG，该10个第一RBG中的每个第一RBG中包括10(即M1＝10)个频域资源连续的RB，该第一带宽包括的第11个RBG中包括7个频域资源连续的RB，即第11个RBG不是第一RBG。第一带宽包括10个第一梳齿，该10个第一梳齿的索引为0到9，其中，一个第一梳齿包括该10个第一RBG中的每个第一RBG中的一个RB，任意一个第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。索引为0～6的第一梳齿包括11个RB，索引为7～9的第一梳齿包括10个RB。

步骤S203、终端设备通过目标梳齿组向网络设备发送信息。
本实施例中，可选地，终端设备根据第一指示信息确定网络设备为终端设备分配的目标梳齿组，并通过目标梳齿组(例如目标梳齿组中的全部资源或部分资源)向网络设备发送上行信息。
可选地，在免许可频谱上，终端设备根据第一指示信息确定目标梳齿组后，需要通过信道检测确定目标梳齿组所占用的频带是否空闲(即该频带是否被其他设备占用)，若目标梳齿组所占用的频带全部空闲，那么终端设备通过目标梳齿组向网络设备发送上行信号；若目标梳齿组所占用的频带部分空闲，那么终端设备通过空闲的频带上的目标梳齿组(即目标梳齿组中的部分资源)向网络设备发送上行信号；若目标梳齿组所占用的频带全部为忙，那么终端设备不在目标梳齿组上发送上行信号。
可选地，在免许可频谱上，终端设备根据第一指示信息确定目标梳齿组后，需要通过信道检测确定目标梳齿组所占用的频带是否空闲(即该频带是否被其他设备占用)，若目标梳齿组所占用的频带全部空闲，那么终端设备通过目标梳齿组向网络设备发送上行信号；否则，终端设备不在第一频域资源上发送上行信号。
示例性的，若第一指示信息指示所述目标梳齿组所包括的梳齿的索引编号，则所述终端设备根据所述目标梳齿组所包括的梳齿的索引编号，确定所述目标梳齿组。示例性的，若第一指示信息指示所述目标梳齿组所包括的梳齿所满足的分配规则，则所述终端设备根据所述目标梳齿组所包括的梳齿所满足的分配规则，确定所述目标梳齿组。当然，所述第一指示信息还可通过其它方式指示所述目标梳齿组，对应地，所述终端设备通过相应的其它方式确定所述目标梳齿组，本申请实施例中对此并不作限制。
可选地，所述目标梳齿组的资源分配方式可以参见本实施例上述步骤201中的相关描述，此次不再赘述。
步骤S204、网络设备通过目标梳齿组接收终端设备发送的信息。
本实施例中，网络设备通过目标梳齿组(例如目标梳齿组中的全部资源或部分资源)接收终端设备发送的上行信号。
可以理解的是，当终端设备在发送上行信号前需要通过信道检测确定目标梳齿组所占用的频带是否空闲，只有确定频带空闲才能进行信号发送时，相应地，网络设备可以先确定终端设备发送信号的频带，然后再通过终端设备发送的频带中的目标梳齿组(例如所述目标梳齿组中的全部资源或部分资源)接收所述终端设备发送的上行信号。可选地，网络设备可以通过检测参考信号的存在性来确定终端设备发送信号的频带。
可选地，第一带宽包括第一子带，第一子带包括N1个第一RBG中频域资源连续的S1个第一RBG，网络设备可以通过盲检测第一子带上的RS(参考信号，Reference Signal)的存在性来判断终端设备是否可以使用第一带宽以及第一子带，当网络设备确定终端设备可以使用第一子带但不可以使用第一带宽中的至少一部分资源时，网络设备可以向终端设备发送指示信令，以便终端设备确定第一子带为终端设备确定为可用的频域资源，且第一带宽中至少有一部分资源为终端确定为不可用的频域资源；或者，网络设备无需向终端发送指示信令，终端设备可以通过信道检测来确定第一子带为终端设备确定为可用的频域资源，且第一带宽中至少有一部分资源为终端确定为不可用的频域资源。
进一步地，网络设备通过目标梳齿组接收终端设备发送的信息之前还包括：网络设备根据第一子带确定目标梳齿组中的可用频域资源；对应地，网络设备通过目标梳齿组中的可用频域资源从终端设备接收信息。
本实施例提供的信息传输方法应用于包括网络设备和终端设备的通信系统，通信系统使用的载波上的第一带宽包括N1个第一资源块组RBG，至少两个第一RBG中的每个第一RBG中包括M1个频域资源连续的资源块RB；终端设备通过接收网络设备发送的第一指示信息，第一指示信息用于指示终端设备从当前候选集合中确定目标梳齿组，当前候选集合包括第一候选集合，其中，第一候选集合包括至少两个第一梳齿组，第一梳齿组包括至少一个第一梳齿，第一梳齿包括至少两个第一RBG中的每个第一RBG中的一个RB；进一步地，终端设备根据第一指示信息从当前候选集合中确定目标梳齿组，并通过目标梳齿组向网络设备发送信息；进一步地，网络设备通过目标梳齿组从终端设备接收信息。可见，本申请实施例提供的信息传输方法不仅可以适用于不同带宽大小的信息传输，并且通过梳齿状的资源分配方式还可以提高信息的发射功率，进而提高信息的传输机会和传输性能。
在上述实施例的基础上，作为示例，如图9所示，本申请以第一载波的系统带宽为80MHz，子载波间隔为60kHz为例，对根据本申请实施例的资源分配图案进行举例说明。
如图9所示，第一载波上的系统带宽内可以包括9个子带，其中，子带#0，#1，#2，#3的带宽分别为20MHz，子带#4，#5，#6的带宽分别为40MHz，子带#7和#8的带宽分别为60MHz。其中，在任意一个子带的两边均预留一定的频域资源，用于避免RF的影响，该预留的资源不用于信号传输。对于终端设备来说，用于传输信号的第一带宽可 以被配置为第一载波的系统带宽，也可以被配置为上述任意一个子带对应的带宽。
第一载波上的系统带宽包括111个RB，标号为从0到110，其中，该系统带宽两侧各预留2个RB用于避免RF影响，即该系统带宽的有效频域资源部分包括107个RB，标号为从2到108。该107个RB包括10(即N1＝10)个第一RBG，该10个第一RBG中的每个第一RBG中包括10(即M1＝10)个频域资源连续的RB，该第一带宽包括的第11个RBG中包括7个频域资源连续的RB，即第11个RBG不是第一RBG。该系统带宽包括10个第一梳齿，该10个第一梳齿的索引为0到9，其中，一个第一梳齿包括该10个第一RBG中的每个第一RBG中的一个RB，任意一个第一梳齿中包括的频域相邻的任意两个RB之间的频域间隔相等。索引为0～6的第一梳齿包括11个RB，索引为7～9的第一梳齿包括10个RB。
