在第二方面中，第一频段的带宽能力信息用于指示终端的第一频段的下行带宽能力，无线接入网节点在分配的资源上发送或接收信号，包括：无线接入网节点在分配的资源上接收下行信号，其中，第二方面的方法进一步包括：无线接入网节点接收终端上报的多个频段中的第一频段的第二带宽能力信息，其中第二带宽能力信息用于指示终端的第一频段的上行带宽能力，第一频段的上行带宽能力不小于第二阈值，第二阈值根据终端的最大带宽能力或者根据所述第一频段或第一频段的子载波间隔确定；无线接入网节点在根据第二带宽能力信息分配的资源上发送上行信号。第二阈值小于或等于所述第一阈值。
由于上行带宽能力的最小阈值的定义可以不考虑对同步信号块的完整接收的影响，上行带宽能力的最小阈值的定义独立于下行带宽能力的最小阈值的定义有助于降低设计的复杂度。

具体实施方式
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端(Terminal)，又称之为用户设备(User Equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑(Pad)、笔记本电脑、掌上电脑、移动互联网设备(Mobile Internet Device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等
2)、无线接入网(Radio Access Network，RAN)是网络中将终端接入到无线网络的部分。RAN节点或设备为无线接入网中的节点或设备，又可以称为基站。目前，一些RAN节点的举例为：gNB、传输接收点(Transmission Reception Point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，或Wifi接入点(Access Point，AP)等。另外，在一种网络结构中，RAN可以包括集中单元(Centralized Unit，CU)节点和分布单元(Distributed Unit，DU)节点。这种结构将长期演进(Long Term Evolution，LTE)中eNB的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在各个DU中，由CU集中控制各个DU。本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。
3)、“多个”是指两个或两个以上，其它量词与之类似。“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。
4)、系统带宽，也称为最大载波带宽，是指每个载波的最大信道带宽(maximum channel bandwidth per carrier)。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：LTE系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、第4.5(4.5th generation，4.5G)代网络、5G网络、NR等。
在长期演进(long term evolution，LTE)系统中，系统工作在小于3GHz的单一频段，在该频段上，系统带宽为20MHz，终端支持的带宽能力的最小值定义为20MHz，与系统带宽相同。这样，在LTE系统中，对于给定频段，所有终端的支持的带宽能力的最小值均不小于系统带宽。因此，RAN节点无需获知终端的带宽能力，自行决定在1.44M到20M的系统带宽下工作。
在多个频段通信系统中，由于终端在不同频段所支持的带宽可以不同，所以如果针对不同的频段仍然为终端定义统一的带宽能力的最小值会造成资源配置的灵活性降低或者增加设计的复杂性。例如，在NR系统中，系统带宽可以为400MHz，而终端支持的带宽可以大于或等于100MHz，也可以小于100MHz，即系统带宽可以大于终端支持的带宽。在这种情况下，本申请实施例针对不同频段或不同终端定义了终端的带宽能力的最小值，且终端可以向RAN节点上报满足该最小值约束的带宽能力，使得RAN节点可以根据终端上报的带宽能力分配资源，提高了资源配置的灵活性。例如，本申请的实施例中，终端可以向RAN节点上报带宽能力，且该带宽能力满足阈值的约束，该阈值可以根据终端的最大带宽能力确定，或者可以根据第一频段或该第一频段的子载波间隔确定，这样，终端可以向RAN节点上报满足上述阈值的宽带能力，使得RAN节点可以根据终端上报的带宽能力分配资源，提高了资源配置的灵活性。
下面将结合附图，对本申请中的技术方案进行描述。
图1是根据本申请的一个实施例的通信系统100的示意性系统架构图。
如图1所示，该移动通信系统包括RAN节点(如图1中的基站110)和至少一个终端(如图1中的终端120和终端130)。终端通过无线的方式与RAN节点相连。RAN节点可以通过无线或有线方式与核心网设备连接(图1未示出)。核心网设备与RAN节点可以是独立的不同的物理设备，也可以是将核心网设备的功能与RAN节点的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的RAN节点的功能。终端可以是固定位置的，也可以是可移动的。
RAN节点和终端可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请的实施例对RAN节点和终端的应用场景不做限定。
本申请的实施例的通信系统为多频段的通信系统，可以支持多个频段(例如，小于3GHz的频段、3GHz至6GHz的频段和大于6GHz的频段)的通信。
应理解，图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备(未示出)。本申请的实施例对该移动通信系统中包括的核心网设备、RAN节点和终端的数量不做限定。
图2是根据本申请的一个实施例的一种传输信号的方法的示意性流程图。该方法用于多频段的通信系统。该方法可以由图1的RAN节点或终端执行。图2的方法包括如下内容。
210，终端向RAN节点上报多个频段中的第一频段的带宽能力信息，其中终端的工作频段包括第一频段，第一频段的带宽能力信息用于指示终端的第一频段的带宽能力，第一频段的带宽能力不小于第一阈值，第一阈值根据终端的最大带宽能力确定或者根据第一频段或第一频段的子载波间隔确定。
这里，第一频段可以是多个频段中的任一频段。多个频段中的每个频段可以包括至少一种子载波间隔。对于数据信号而言，不同的频段可以包括相同或不同的子载波间隔，例如，小于3GHz的频段可以包括15kHz和30kHz两种子载波间隔，而3GHz至6GHz的频段可以使用30kHz和60kHz两种子载波间隔。对同步信号块而言，不同的频段可以使用不同的子载波间隔，例如，小于3GHz的频段可以使用30kHz的子载波间隔，而3GHz至6GHz的频段可以使用60kHz的子载波间隔。
终端的最大带宽能力是指终端理论上能够提供的最大带宽，例如，该最大带宽能力可以是射频带宽能力(即最大射频带宽)和基带带宽能力(最大基带带宽)中的最小值。进一步，终端的第一频段的带宽能力也称为终端在第一频段上的支持的带宽，也称为实际的最大带宽，该实际的最大带宽可以设计为不小于第一阈值。第一阈值可以指终端支持的带宽的最小值。
此外，该终端上报的第一频段的带宽能力信息小于或者等于该终端的最大带宽能力，也就是说，终端实际上报的任一个工作频段的带宽能力信息是小于或等于其能够提供的最大带宽的。
220，RAN节点可以根据终端上报的带宽能力信息分配资源。
具体而言，RAN节点可以基于预设的规则和终端上报的带宽能力信息分配资源。例如，基于可以根据系统带宽和网络状态(例如，吞吐量、负载、拥塞等网络状态)中的至少一个和终端上报的带宽能力信息为终端分配资源。本申请的实施例对分配资源的方式不 作限定，例如，还可以根据高层信令的指示和终端上报的带宽能力分配资源。
RAN节点可以在整个系统带宽中为终端分配部分带宽资源，或者RAN节点也可以在系统带宽中划分一个子带，并在该子带内为终端分配带宽资源。
230，RAN节点和终端在分配的资源上发送或接收信号。
当RAN节点为终端分配下行资源时，RAN节点在分配的资源上发送信号，终端接收信号；当RAN节点为终端分配上行资源时，终端在分配的资源上发送信号，RAN节点接收信号。
在多频带通信系统中，终端在某些频段上所支持的带宽能力有可能会小于系统带宽，而在另一些频段上所支持的带宽能力也可能会大于系统带宽，在这种情况下，在设计终端时，终端所支持的带宽能力的最小值不再适合采用统一的阈值来限定，终端的某个频段的带宽能力可以设计为不小于某个最小值(即第一阈值)。
根据本申请的实施例，第一阈值可以根据终端的最大带宽能力来确定，由于终端的最大带宽能力是不同的，因此，终端向RAN节点发送的带宽能力可以在第一阈值与最大带宽能力之间根据实际需要灵活确定。
可替代地，作为另一实施例，第一阈值还可以根据第一频段或该第一频段的子载波间隔确定。例如，可以针对不同的频段为终端设计不同的第一阈值，或者可以针对不同的频段的子载波间隔为终端设计不同的第一阈值。例如，不同的频带可能具有不同的子载波间隔，对于不同的子载波间隔，第一阈值可以定义为与不同子载波间隔对应的取值，例如，第一频带具有第一子载波间隔，而第二频带具有第二子载波间隔，这样，第一频带的第一子载波间隔对应的第一阈值可以不同于第二子载波间隔对应的第一阈值。
进一步地，RAN节点在与终端进行通信时，RAN节点可以接收终端上报的带宽能力信息，并根据终端的带宽能力信息指示的终端的带宽能力为终端分配资源，并在分配的资源上与终端进行通信。例如，RAN节点在进行资源配置时要满足终端设备的带宽要求。
根据本申请的实施例，通过为终端的带宽能力设计最小阈值，并且将该最小阈值定义为根据终端的最大带宽能力确定或者根据第一频段或该第一频段的子载波间隔确定，使得RAN节点可以根据终端上报的不同带宽能力分配资源并进行信号传输，提高了资源配置的灵活性。
根据本申请的实施例，第一阈值根据终端的最大带宽能力确定，最大带宽能力可以由终端支持的射频带宽能力(即最大射频带宽)和基带带宽能力(最大基带带宽)来确定，例如，最大带宽能力为终端的射频带宽能力和基带带宽能力中的最小值。基带带宽能力为第一频段的子载波间隔与终端采用的最大FFT点数的乘积。可替代地，上述基带带宽能力还可以为第一频段的子载波间隔与终端采用的最大采样点数的乘积。第一阈值小于或等于乘积和终端的射频带宽能力中的最小值。例如，系统带宽为200MHz，终端的射频带宽能力也为200MHz，而终端的基带带宽能力可以为100MHz，在这种情况下，终端的最小带宽能力为100MHz，第一阈值可以设计为小于或等于100MHz，例如，80MHz。
根据本申请的实施例，通过将第一阈值的确定与终端的最大FFT点数或采样点数以及每个频段的各个子载波间隔相关联，提高了资源配置的灵活性，降低了设计复杂度。另外，通过将最大带宽能力定义为射频带宽能力和基带带宽能力中的最小值，并将第一阈值定义为小于或等于该最小值，保证了信号传输的可靠性。
根据本申请的实施例，第一阈值根据第一频段确定，多个频段中的不同频段对应的同步信号块的频域宽度不同，多个频段中的不同频段对应的第一阈值不同。
在NR系统中，同步信号块(SS block)可以为时频资源块，同步信号除了可以包括主同步信号(primary SS)和/或辅同步号(secondary SS)之外，还可以包括主信息块(MIB)。在进行时间同步(time synchronization)时,可以以SS块为最小单位进行传输，当检测到某个SS块后，可以获知时间同步信息。
在多频带场景下，不同的频段的同步信号块的频域宽度可以不同，例如，子载波间隔为30kHz、120kHz、240kHz的同步信号块分别对应于小于3GHz的频段、3GHz至6GHz的频段、大于6GHz的频段，相应的频域宽度分别为10MHz、40MHz、80MHz。频域宽度也称为传输带宽。
根据本申请的实施例，第一频段对应的第一阈值大于或等于第一频段对应的同步信号块的频域宽度。可选地，可以针对不同的频段或子载波间隔为终端设计不同的最大FFT点数，从而影响终端的基带带宽能力，在这种情况下，同样也可以根据终端的最小带宽能力来确定第一阈值。
例如，第一频段为小于3GHz的频段时，同步信号块的频域宽度可以为10MHz，因此，第一阈值可以设计为大于或等于10MHz；第一频段为3GHz至6GHz的频段时，同步信号的频域宽度可以为40MHz，因此，第一阈值可以设计为大于或等于40MHz；第一频段为大于6GHz的频段时，在这种情况下，同步信号的频域宽度可以为80MHz，因此，第一阈值可以设计为大于或等于80MHz。
根据本申请的实施例，通过将不同频段对应的第一阈值设置为不同且大于或等于相应的频域宽度，保证了终端能够完整地接收不同频段的同步信号块，从而保证了信号传输的可靠性，降低了设计复杂度。
根据本申请的实施例，第一阈值根据第一频段的子载波间隔确定，多个频段的不同子载波间隔对应的同步信号块的频域宽度不同，多个频段的不同子载波间隔对应的第一阈值不同。第一频段对应的第一阈值大于或等于第一频段对应的同步信号块的频域宽度。
例如，第一频段为小于3GHz的频段时，子载波间隔为30kHz，同步信号块的频域宽度可以为10MHz，因此，第一阈值可以设计为大于或等于10MHz；第一频段为3GHz至6GHz的频段时，子载波间隔为120kHz、同步信号的频域宽度可以为40MHz，因此，第一阈值可以设计为大于或等于40MHz；第一频段为大于6GHz的频段时，子载波间隔为240kHz。同步信号的频域宽度可以为80MHz，因此，第一阈值可以设计为大于或等于80MHz。
通过将不同子载波间隔对应的第一阈值设置为不同且大于或等于相应的频域宽度，保证了终端能完整地接收不同频段的同步信号块，从而保证了信号传输的可靠性，降低了设计复杂度。
应理解，上述频段、子载波间隔和频域宽度的取值仅仅是举例，在不同的系统场景下，上述频段、子载波间隔和频域宽度可以是其它取值。
根据本申请的实施例，第一频段的带宽能力信息用于指示终端的第一频段的下行带宽能力或上行带宽能力。换句话说，上述方案既适用于上行信号传输，也适用于下行信号传输。
根据本申请的实施例，第一频段的带宽能力信息用于指示终端的第一频段的下行带宽能力，终端在网络侧设备根据带宽能力信息分配的资源上发送或接收信号，包括：终端在网络侧设备根据带宽能力信息分配的资源上接收下行信号，其中，方法进一步包括：终端向RAN节点上报多个频段中的第一频段的第二带宽能力信息，其中第二带宽能力信息用于指示终端的第一频段的上行带宽能力，第一频段的上行带宽能力不小于第二阈值，第二阈值根据终端的最大带宽能力或者根据第一频段或该第一频段的子载波间隔确定；终端在网络侧设备根据第二带宽能力信息分配的资源上发送上行信号。第二阈值小于或等于第一阈值。
由于上行带宽能力的最小阈值的定义可以不考虑对同步信号块的完整接收的影响，上行带宽能力的最小阈值的定义独立于下行带宽能力的最小阈值的定义有助于降低设计的复杂度。
应理解，上述第一带宽能力信息和第二带宽能力信息可以分别携带在不同的消息中上报，也可以携带在同一个消息中上报。
根据本申请的实施例，多个频段中的不同频段对应的第一阈值与第二阈值的差值不同。由于上行带宽能力的最小值可以不同于下行带宽能力的最小值，因此，可以降低终端上行带宽能力需求，从而降低终端上行射频、基带设计复杂度。
图3是根据本申请的另一实施例的传输信号的过程的示意性流程图。图3是图2的方法的例子。本实施例以RAN节点为基站为例进行说明。
305，终端确定终端的带宽能力信息。
例如，终端可以根据预先设置的支持带宽能力的最小值(即图2的实施例中的第一阈值)确定终端支持的带宽能力。该带宽能力不小于第一阈值并且也不超出终端的最大带宽能力(即射频带宽能力和基带带宽能力中的最小值)。
终端上报的终端带宽能力信息，可以是一个确切的带宽值或者用于指示该带宽值的编号或索引，本申请的实施例并不限于此，带宽能力信息也可以包括射频带宽和FFT点数，在这种情况下，基站可以根据终端上报的射频带宽和FFT点数估计终端的带宽能力。
进一步地，终端还可以根据自身业务吞吐量需求、处理时延、功率消耗等状态信息的任意组合确定终端能够支持的带宽能力，这样，终端上报的带宽能力可能小于终端的最大带宽能力，或者终端上报的射频带宽能力、FFT点数小于射频带宽能力、最大FFT点数。例如，当终端需要获得大吞吐量时，上报的带宽能力可以接近终端最大带宽能力，或者当终端需要较低处理时延或者较低功率消耗时，终端上报的带宽能力可以较小。
终端上报的终端带宽能力可以满足如下条件：第一阈值≤终端带宽能力≤min(终端射频带宽能力，最大FFT点数×子载波间隔)。其中，最大FFT点数×子载波间隔为终端的基带带宽能力。
以下表为例，假设终端支持的最大射频带宽为200MHz，最大FFT点数为4096，则根据上述公式可以计算在各SCS下的终端的最大带宽能力为：
表1
Figure PCTCN2018079717-appb-000001
Figure PCTCN2018079717-appb-000002
参见表1，小于3GHz的频段对应的子载波间隔为15kHz和30kHz，对应的最大带宽为61MHz和122MHz；3至6GHz的频段对应的子载波间隔为30kHz和60kHz，对应的最大带宽为122MHz和200MHz；大于6GHz的频段对应的子载波间隔为60kHz、120kHz和240kHz，对应的最大带宽均为200MHz。
第一阈值的定义可以有至少两种，结合表1举例说明如下：
1、第一阈值可以定义为不大于终端在所有可能频段(或SCS)下的最大带宽的最小值。参见表1，该最小值为上表最右列的最小值，即第一阈值不大于61MHz。
2、第一阈值可以定义为不大于终端在给定频段所有可能SCS下的最大带宽的最小值。参见表1，当终端工作在<3GHz频段时，第一阈值不大于61MHz；当终端工作在3GHz至6GHz频段时，第一阈值不大于122MHz；当终端工作在>6GHz频段时，第一阈值不大于200MHz。
基于上述定义，可能会出现终端带宽小于同步信号块的频域宽度的情况。由于终端在接收同步信号时，往往是通过滤波器截取检测的。因此，这种情况下，同步信号为多个子序列的频分多路复用(Frequency Division Multiplexing，FDM)组合。各子序列的长度为一个预定义的大小，且各子序列所在频域资源之间留有若干子载波作为保护间隔。对于小带宽用户，通过接收一个子序列检测同步信号；对于大带宽用户，通过接收多个子序列检测同步信号。另外，不同的频带对应的频域宽度不同。因此，为了完整地接收同步信号块，以降低设计复杂度，可以将第一阈值进一步限定为大于或等于同步信号块的频域宽度。
当然，作为上述两种定义的替代方案，也可以仅仅将第一阈值限定为大于或等于同步信号块的频域宽度。
310，终端向基站上报带宽能力信息。
终端可以通过物理上行信道上报带宽能力信息。例如，终端可以通过物理随机接入信道(Physical Random Access Channel，PRACH)、物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)等物理上行信道向基站上报终端的带宽能力信息。
终端可以在随机接入过程中向基站上报带宽能力终端可以通过多种方式上报带宽能力。例如可以采用如下现有信令消息携带：
1、终端可以在初始接入时上报，例如利用或通过前导(preamble)上报，适用于终端发起基于竞争的随机接入过程或者基于非竞争的随机接入过程，其中前导的序列和/或参数集合(例如子载波间隔)可以根据终端带宽能力确定。这样，可以利用前导序列和/或参数集合来指示终端的带宽能力。
2、终端通过消息3(Msg.3)上报，适用于终端发起基于非竞争的随机接入过程，终端带宽能力信息承载在Msg.3中。
应理解，本申请的实施例并不限于上述上报带宽能力的方式，例如，终端还可以通过 专用的信令消息上报带宽能力信息。
320，基站根据终端上报的带宽能力信息分配资源。
假设系统带宽为X，终端支持的带宽Y<X。基站可以根据终端带宽能力为终端分配资源，例如，基站在系统带宽X中为终端分配带宽为Z≤Y的资源。
330，基站根据为终端分配的资源进行资源调度。
例如，基站采用半静态调度方式和动态调度方式进行资源调度。本申请实施例的资源调度过程与常规资源调度过程类似，在此不再赘述。
340，终端与基站根据分配的资源进行信号传输。
终端与基站根据分配的资源进行信号传输的过程与常规信号传输过程类似，在此不再赘述。
图4是根据本申请的又一实施例的传输信号的过程的示意性流程图。本实施例以RAN节点为基站为例进行说明。
405，终端确定终端的带宽能力信息。405与305类似，在此不再赘述。
410，终端向基站上报带宽能力信息。410与310类似，在此不再赘述。
412，基站根据终端上报的带宽能力信息为终端划分子带。
假设系统带宽为X，终端支持的带宽Y<X。基站为终端在系统带宽X中划分一个带宽为Y的子带。
414，基站向终端通知子带划分结果，用于指示为终端划分的子带。
420，基站在划分给终端的子带进行资源分配。
基站可以在该子带内为终端分配带宽为Z≤Y的资源。
430，基站根据为终端分配的资源进行资源调度。
例如，基站采用半静态调度方式和动态调度方式进行资源调度。本申请实施例的资源调度过程与常规资源调度过程类似，在此不再赘述。
440，终端与基站根据分配的资源进行信号传输。
终端与基站根据分配的资源进行信号传输的过程与常规信号传输过程类似，在此不再赘述。
