具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
相关技术中，由于轻型UE的系统带宽较小，因此在轻型UE进行跳频时可能会导致轻型UE跳出系统带宽，无法工作。因此，如何避免轻型终端在跳频时跳出系统带宽成为了亟待解决的问题。
针对这一问题，本公开实施例提供了跳频控制方法及装置。
图1为本公开实施例提供的一种跳频控制方法的流程示意图，由UE执行。在该实施例之中，轻型UE和非轻型UE使用相同的初始上行BWP(带宽部分)。如上所述的，如果轻型UE和非轻型UE所采用的跳频机制一样，则出现轻型UE在某跳跳频时跳出轻型UE的系统带宽的情况。因此，在本公开的实施例之中，在轻型UE和非轻型UE所采用的跳频机制一样的前提下，可根据UE的类型对跳频参数进行调整，以避免出现轻型UE跳出其系统带宽范围的情况。
在本公开的实施例之中，UE在确定跳频偏移值、跳频次数和跳频时域粒度跳频等参数后，可以按照确定的跳频参数进行跳频。需要说明的是，在本公开的实施例中，跳频参数包括跳频偏移值、跳频次数和跳频时域粒度，其中，跳频偏移值，用于确定每一跳的起始位置；跳频次数，用于通过配置多个频域位置，可以获得更高的频率分集增益；跳频时域粒度，用于通过扩展时域跳频的基本粒度,可以支持实现Cross-slot(跨时隙)联合信道估计，或者针对低流动性或静止UE,降低其DMRS(Demodulation Reference Signal，解调参考信号)密度等。
如图1所示，该跳频控制方法包括以下步骤：
步骤101，确定UE的类型。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。在LTE 4G系统中，为了支持物联网业务提出了MTC(机器类通信，Machine Type Communications)，NB-IoT(窄带物联网)两大技术。这两大技术主要针对的是低速率，高时延等场景，比如抄表，环境监测等场景。NB-IoT目前最大只能支持几百k的速率，MTC目前最大只能支持几M的速率。但同时另外一方面，随着物联网业务的不断发展，比如视频监控，智能家居，可穿戴设备和工业传感监测等业务的普及。这些业务通常要求几十到100M的速率，同时对时延也有相对较高的要求，因此LTE中的MTC,NB-IoT技术很难满足要求。在该实施例之中，将这种新的UE类型统称为Reduced capability UE，即轻型UE，而目前的普通终端，在本公开的实施例之中称之为非轻型UE。
在本公开的一个实施例之中，通常轻型UE具有以下特点：
-低造价，低复杂度
-一定程度的覆盖增强
-功率节省。
由于目前的NR新空口是针对高速率低时延等高端终端设计的，因此当前的设计无法满足轻型UE的上述要求。因此需要对目前的NR系统进行改造用以满足轻型UE的要求。比如，为了满足低造价，低复杂度等要求，可以限制轻型UE的带宽，比如限制到10M Hz或者20M Hz,或者限制轻型UE的接收天线数量。针对功率节省，可能的优化方向是减少用户设备的处理复杂度，如在同一个时隙中只接收PDCCH(物理下行控制信道，Physical Downlink Control Channel)信道，在同一时隙的其他符号时刻则进入微睡眠状态。对于一定程度的覆盖增强，还可对各个信道进行多次重复传输，降低码率等。
在本公开的一个实施例中，可根据带宽的大小，确定UE类型。在本公开的一个实施例之中，基站可以获知UE的带宽，根据UE的带宽大小，可以获知该UE的类型，即轻型UE或非轻型UE。在本公开的其他实施例之中，还可根据物理随机接入信道(physical random accesschannel，PRACH)对两种UE的类型进行区分。
如图2所示，在本公开的一个实施例中，跳频偏移值用于确定每一跳的起始位置；跳频次数可理解为跳频的跳数：比如Message3重复传输8次，跳频时域粒度是1个slot，跳数可以为4，那么跳频模式可如图2所示，其中，也就是说，在repetition过程中，msg3的传输有4个不同的频域位置(如图2之中的灰色部分)。
步骤102，根据UE的类型确定跳频参数。
在本公开的实施例之中，跳频参数包括跳频起始位置、跳频偏移量以及跳频次数之中的一个或多个。在本公开的一个实施例之中，跳频参数是根据UE的类型来决定的。具体而言，可以为轻型UE设置独立的跳频参数，并为非轻型UE设置独立的跳频参数。在本公开的实施例之中，轻型UE可以根据自身的系统带宽进行跳频参数的设置，从而避免在跳频时出现跳出轻型UE系统带宽的情况。在本公开的另一个是实施例之中，也还可以为轻型UE和非轻型UE设置相同的跳频参数，该跳频参数需要兼顾轻型UE，避免其跳出轻型UE的系统带宽范围的情况。或者，还可以保持目前非轻型UE的跳频参数不变，对轻型UE的跳频参数进行调整。
在本公开的实施例之中，可对跳频起始位置、跳频偏移量以及跳频次数之中的一个或多个进行调整，以避免出现跳出轻型UE的系统带宽范围的情况。
步骤103，根据确定的跳频参数进行跳频。
在本公开的实施例之中，可以根据UE确定的跳频参数进行跳频。例如根据跳频起始位置、跳频偏移量以及跳频次数进行跳频。
在本公开的实施例之中，可以根据UE的类型对跳频参数进行调整，从而避免跳出轻型UE的系统带宽范围的情况发生。
图3为本公开实施例提供的一种跳频控制方法的流程示意图，由UE执行，UE在确定跳频偏移值、跳频次数和跳频时域粒度等跳频参数之后，可以按照确定的跳频参数进行跳频。需要说明的是，在本公开的实施例中，跳频参数包括跳频偏移值、跳频次数和跳频时域粒度，其中，跳频偏移值，用于确定每一跳的起始位置；跳频次数，用于通过配置多个频域位置，可以获得更高的频率分集增益；跳频时域粒度，用于通过扩展时域跳频的基本粒度,可以支持实现Cross-slot(跨时隙)联合信道估计，或者针对低流动性或静止UE,降低其DMRS(Demodulation Reference Signal，解调参考信号)密度等。
如图3所示，在该实施例之中，跳频参数可为跳频起始位置。该跳频控制方法包括以下步骤：
步骤301，确定UE的类型。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。
步骤302，根据UE的类型确定对应的跳频起始位置。
在本公开的一个实施例之中，对于非轻型UE和轻型UE可以通过相同的方式确定跳频起始位置。但是对于轻型UE而言，在确定了轻型UE的跳频起始位置之后，需要对轻型UE的跳频起始位置进行调整，从而避免跳出轻型UE的系统带宽范围的情况发生。
在本公开的一个实施例中，可通过以下方式确定跳频参数为跳频起始位置。
在本公开的一个实施例中，响应于UE为轻型UE，首先确定轻型UE的起始跳频初始位置，然后根据起始跳频初始位置确定跳频起始位置。
其中，在本公开的一个实施例中，可根据轻型UE的系统带宽确定对应的调整值，再根据调整值对起始跳频初始位置进行调整，从而确定跳频起始位置。
其中，在本公开的一个实施例之中，调整值通过以下方式确定：
协议规定；或者，通过基站发送的信令配置。
在本公开的一个实施例之中，调整值可以通过协议的方式固定，也可以由基站进行动态配置。
在本公开的一个实施例之中，例如确定的起始跳频初始位置为n，且该n出现了跳出轻型UE系统带宽的问题，则需要对n进行调整。在本公开的另一个实施例之中，例如确定第n跳的的起始跳频初始位置为a，且a跳出了轻型UE所支持的最大系统带宽，那么第n跳的跳频起始位置可以为第n-m跳的位置b，其中b在轻型UE系统带宽范围内，并且，n>m。在该实施例之中，m可以通过协议固定，也可以是由基站动态配置。m依据跳频次数决定。
如图4所示为，本公开实施例的跳频起始位置调整示意图。如图4所示，在Slot3(时隙3)时，由于出现超出UE系统带宽的情况，因此对其进行调整，例如减去调整值，例如2，使其回落到轻型UE的系统带宽之中。同样地，对于Slot4而言，也可对其减去调整值，例如2。
其中，在本公开的一个实施例中，响应于起始跳频初始位置未超出UE的系统带宽，可直接将起始跳频初始位置确定为跳频起始位置。
在本公开的一个实施例中，当UE的类型为非轻型UE时，可通过以下方式确定跳频参数为跳频起始位置。
其中，在本公开的一个实施例中，响应于UE为非轻型UE，则将起始跳频初始位置作为跳频起始位置。
在本公开的实施例中，基站可通过向UE发送信令告知UE的调整值。在本公开的一个实施例之中，信令可包括剩余最小系统消息RMSI(Remaining Minimum System Information)信令。
步骤303，根据跳频起始位置进行跳频。
在本公开的一个实施例中，在确定跳频起始位置后，可根据跳频起始位置进行跳频。
在本公开的实施例中，对于轻型UE来说，对其起始跳频初始位置进行调整，从而确定轻型UE对应的跳频起始位置，避免跳出轻型UE的系统带宽范围。
图5为本公开实施例提供的一种跳频控制方法的流程示意图，由UE执行。UE在确定跳频偏移值、跳频次数和跳频时域粒度等跳频参数之后，可以按照确定的跳频参数进行跳频。需要说明的是，在本公开的实施例中，跳频参数包括跳频偏移值、跳频次数和跳频时域粒度，其中，跳频偏移值，用于确定每一跳的起始位置；跳频次数，用于通过配置多个频域位置，可以获得更高的频率分集增益；跳频时域粒度，用于通过扩展时域跳频的基本粒度,可以支持实现Cross-slot(跨时隙)联合信道估计，或者针对低流动性或静止UE,降低其DMRS(Demodulation Reference Signal，解调参考信号)密度等。
如图5所示，在该实施例之中，可以对轻型UE设置对应的跳频起始位置确定公式，从而避免跳出轻型UE的系统带宽范围的情况发生。该跳频控制方法包括以下步骤：
步骤501，确定UE的类型。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。
步骤502，获取当前跳频次数；
在本公开的实施例之中，不同的跳频次数对应的公式不同，因此需要确认跳频次数。
步骤503，根据当前跳频次数生成当前跳频起始位置；
在本公开的实施例之中，对于UE而言，可以将
Figure PCTCN2021072350-appb-000001
作为当前跳频起始位置，其中，i为当前跳频次数，RBstart为当前跳频起始位置，RBoffset为偏移量。
步骤504，根据UE的类型生成调整系数。
在本公开的实施例之中，根据UE的类型生成相应的调整系数，可通过该调整系数对当前跳频起始位置进行调整。

其中，
Figure PCTCN2021072350-appb-000003
为非轻型UE的带宽部分BWP。
在本公开的一个实施例之中，对于轻型UE而言，可根据轻型UE的系统带宽生成该调整系数。在本 公开的另一个实施例之中，对于轻型UE而言，该调整系数为
Figure PCTCN2021072350-appb-000004
其中，
Figure PCTCN2021072350-appb-000005
为非轻型UE的带宽部分BWP，
Figure PCTCN2021072350-appb-000006
为轻型UE的系统带宽。
在本公开的实施例中，基于取模生成的调整系数，还可基于其它方式生成调整系数，对此本公开不作任何限制。
步骤505，根据调整系数和当前跳频起始位置生成跳频起始位置。
在本公开的实施例之中，通过调整系数对当前跳频起始位置进行调整，从而生成跳频起始位置。
步骤506，根据跳频起始位置进行跳频。
在UE确定了自身对应的跳频起始位置之后，按照确定之中的跳频起始位置进行跳频。
在该实施例之中，可根据UE的类型，确定调整系数，从而使得轻型UE，避免跳出轻型UE的系统带宽范围。
在本公开的一个实施例之中，对于多个跳频位置的方式，可以通过以下方式确定轻型UE和非轻型UE的跳频起始位置。
对于非轻型UE而言，可以通过以下公式计算跳频起始位置：

在本公开的另一个实施例之中，对于时隙内跳频(intra-slot)以及两跳时隙间跳频(inter-slot)的方式，还可通过以下公式来确定跳频起始位置。
对于非轻型UE，以及时隙内跳频(intra-slot)而言，可通过以下公式确定跳频起始位置：

在本公开的其他实施例之中，还可以进行多次的跳频，例如对于轻型UE而言，可以通过以下公式 确定跳频起始位置：

在上述实施例之中，可以用于轻型UE支持RAR和Msg3之间进行RFretuning(射频重调)的场景中。
在本公开的实施例之中，根据所述轻型UE的系统带宽和非轻型UE的BWP之中的最小值生成调整系数。在本公开的另一个实施例之中，轻型UE和非轻型UE均使用相同的跳频起始位置确定公式。在该实施例之中，由于轻型UE和非轻型UE使用的公式相同(均采用如上所示的轻型UE的跳频起始位置确定公式)，因此基站无需对二者进行区分。在本公开的另一个实施例之中，根据非轻型UE的BWP和轻型UE的系统带宽之中的最小值生成调整系数，其中，非轻型UE和轻型UE的跳频起始位置均通过该调整系数确定。
图6为本公开实施例提供的一种跳频控制方法的流程示意图，由UE执行。UE在确定跳频偏移值、跳频次数和跳频时域粒度等跳频参数之后，可以按照确定的跳频参数进行跳频。需要说明的是，在本公开的实施例中，跳频参数包括跳频偏移值、跳频次数和跳频时域粒度，其中，跳频偏移值，用于确定每一跳的起始位置；跳频次数，用于通过配置多个频域位置，可以获得更高的频率分集增益；跳频时域粒度，用于通过扩展时域跳频的基本粒度,可以支持实现Cross-slot(跨时隙)联合信道估计，或者针对低流动性或静止UE,降低其DMRS(Demodulation Reference Signal，解调参考信号)密度等。
如图6所示，在该实施例之中跳频参数为跳频偏移量。在本公开的实施例之中，还可通过调整轻型UE的跳频偏移量实现避免跳出轻型UE系统带宽的问题。该跳频控制方法包括以下步骤：
步骤601，确定UE的类型。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。
步骤602，根据UE的类型确定跳频参数为跳频偏移量。
在本公开的一个实施例中，可首先通过获取UE的类型所对应的偏移量配置表，之后获取基站指示的偏移量标识，再根据偏移量标识和UE的类型所对应的偏移量配置表确定跳频偏移量。
在本公开的一个实施例之中，针对UE不同的类型，设置不同的偏移量配置表。
在本公开的一个实施例之中，偏移量配置表可以是协议规定的，也可以是基站通过系统消息通知的。
在本公开的一个实施例之中，可以为非轻型UE和轻型UE配置相同的偏移量配置表，也可以为非轻型UE和轻型UE配置不相同的偏移量配置表。若配置相同的偏移量配置表，需要避免轻型UE跳出自身 系统带宽。
步骤603，根据跳频偏移量进行跳频。
UE根据以上步骤确定的跳频偏移量进行跳频。
在本公开的实施例之中，可以对轻型UE的跳频偏移量进行调整，从而避免轻型UE出现跳出系统带宽范围的问题。
在本公开的一个实施例之中，当UE为非轻型UE，则非轻型UE对应的第一偏移量配置表之中的跳频偏移量根据非轻型UE的BWP确定；当UE为轻型UE，则轻型UE对应的第二偏移量配置表之中的跳频偏移量根据轻型UE的系统带宽确定。
在该实施例之中，对于时隙内跳频(intra-slot)，非轻型UE可以使用如下的第一偏移量配置表：
Figure PCTCN2021072350-appb-000018
表1
在该实施例之中，对于时隙内跳频(intra-slot)，轻型UE可以使用如下的第二偏移量配置表：
Figure PCTCN2021072350-appb-000019
表2
在本公开的一个实施例之中，上述表1和表2可通过协议的方式固定。也可通过基站指示的方式配置到UE之中。
在本公开的其他实施例之中，对于两跳的时隙间跳频，非轻型UE可以使用如下的第一偏移量配置表：
Figure PCTCN2021072350-appb-000020
表3
在本公开的其他实施例之中，对于两跳的时隙间跳频，轻型UE可以使用如下的第二偏移量配置表：
Figure PCTCN2021072350-appb-000021
表4
其中，在本公开的一个实施例中，在偏移量配置表之中，非轻型UE对应的跳频偏移量由非轻型UE的BWP确定，轻型UE对应的跳频偏移量由非轻型UE的BWP和轻型UE的系统带宽之中的最小值确定。
在本公开的一个实施例之中，还可通过系统消息给UE配置上述偏移量配置表。
在本公开的实施例之中，非轻型UE和轻型UE可均使用第二偏移量配置表。
在本公开的一个实施例之中，还可以针对多跳设置偏移量配置表。
在本公开的其他实施例之中，对于三跳的时隙间跳频，非轻型UE可以使用如下的第一偏移量配置表：
Figure PCTCN2021072350-appb-000022
表5
在本公开的其他实施例之中，对于三跳的时隙间跳频，轻型UE可以使用如下的第二偏移量配置表：
Figure PCTCN2021072350-appb-000023
表6
在本公开的实施例之中，上述第一偏移量配置表5和第二偏移量配置表6可通过协议规定，也可以通过系统消息通知。
在本公开的实施例之中，还将第一偏移量配置表和第二偏移量配置表合并。该合并之中的表对于轻型UE和非轻型UE均适用，如下表所示。
Figure PCTCN2021072350-appb-000024
表7
在本公开的一个实施例中，可将多个跳频偏移值配置表汇总至一个大表中，之后再将第一偏移量标识作为索引值进行检索。由于将多个跳频偏移值配置表汇总至一个表中，导致该大表较长，因此相应动态信令中需要扩展比特位来指示其索引。其中，扩展的比特位可复用RARULgrant中的TPC(功控)字段。
在本公开的一个实施例中，当需要进行重复时，此时覆盖较差，终端一般使用满功率发送，此时TPC(功控)字段无效，因此可以复用该TPC字段作为扩展的比特位(即第一偏移量标识)。
在本公开的一个实施例之中，基站可以设置第一偏移量配置表和第二偏移量配置表，或者，也可以设置第一偏移量配置表或第二偏移量配置表。如果BWP大于轻型UE的系统带宽，则在基站之中配置第一偏移量配置表和第二偏移量配置表。如果BWP小于或等于轻型UE的系统带宽，则在基站之中只配置第一偏移量配置表，轻型UE也使用该第一偏移量配置表。
在本公开的一个实施例之中，基站可以设置第一偏移量配置表和第二偏移量配置表，非轻型UE使用第一偏移量配置表进行跳频起始位置的确定，轻型UE使用第二偏移量配置表进行跳频起始位置的确定。
在本公开的一个实施例之中，如果上述偏移量配置表由系统消息通知，则在该实施例之中可以只发送第二偏移量配置表，非轻型UE和轻型UE均使用第二偏移量配置表进行跳频起始位置的确定。这样基站可以无需对UE进行类型区分。
在本公开的一个实施例之中，偏移量不仅可以通过上述的偏移量配置表设定，还可以通过协议设定，或者基站的系统消息配置。
图7为本公开实施例提供的一种跳频控制方法的流程示意图，由UE执行，以在UE在确定跳频偏移值、跳频次数和跳频时域粒度等跳频参数之后，可以按照确定的跳频参数进行跳频。需要说明的是，在本公开的实施例中，跳频参数包括跳频偏移值、跳频次数和跳频时域粒度，其中，跳频偏移值，用于确定每一跳的起始位置；跳频次数，用于通过配置多个频域位置，可以获得更高的频率分集增益，跳频时域粒度，用于通过扩展时域跳频的基本粒度,可以支持实现Cross-slot(跨时隙)联合信道估计，或者针对低流动性或静止UE,降低其DMRS(Demodulation Reference Signal，解调参考信号)密度等。
如图7示，在该实施例之中跳频参数为跳频次数。在本公开的实施例之中，还可通过调整轻型UE的跳频次数实现避免跳出轻型UE系统带宽的问题。该跳频控制方法包括以下步骤：
步骤701，确定UE的类型。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。
步骤702，根据UE的类型确定跳频参数为跳频次数。
在本公开的实施例中，如果UE为非轻型UE，则将第一跳频次数作为非轻型UE的跳频次数；如果 UE为轻型UE，则将第二跳频次数作为轻型UE的跳频次数，其中，第一跳频次数大于第二跳频次数。
在本公开的实施例中，非轻型UE支持的跳频次数大于轻型UE支持的跳频次数。
在本公开的实施例中，上述第一跳频次数和第二跳频次数，通过基站的RMSI、随机接入响应RAR或下行控制信息DCI指示。
在本公开的实施例中，第一跳频次数和第二跳频次数由协议配置或者基站指示。在本公开的一个实施例之中，基站可通过RMSI广播第一跳频次数和第二跳频次数。
在本公开的实施例中，非轻型UE对应的跳频次数由基站指示，轻型UE的对应的跳频次数由协议规定。
在本公开的另一个实施例中，判断非轻型UE的BWP是否大于轻型UE的系统带宽；如果大于轻型UE的系统带宽，则将第一预设次数作为非轻型UE的跳频次数，并将第二预设次数作为轻型UE的跳频次数，其中，第一预设次数大于第二预设次数；如果小于或等于轻型UE的系统带宽，则将第一预设次数作为非轻型UE和轻型UE的跳频次数。
在本公开的另一个实施例中，接收基站指示的第一指示次数和第二指示次数，其中，第一指示次数大于第二指示次数；如果非轻型UE的BWP大于轻型UE的系统带宽，则将第一指示次数作为非轻型UE的跳频次数，并将第二指示次数作为轻型UE的跳频次数
在本公开的另一个实施例中，接收基站指示的第三指示次数。如果非轻型UE的第一BWP小于或等于轻型UE的第二BWP，则将第三指示次数作为非轻型UE和轻型UE的跳频次数
需要说明的是，上述第一指示次数和第二指示次数，或者第三指示次数，通过基站的RMSI、随机接入响应RAR或下行控制信息DCI指示。
在本公开个一个实施例之中，也还可为轻型UE通知或设置预设的值，例如0，即对轻型UE来说不进行跳频。
在该实施例之中，可适用于时隙内跳频的方式，也可适用于时隙间跳频的方式。
在本公开个一个实施例之中，可以将非轻型UE的跳频次数由基站进行配置，对于轻型UE的跳频次数，也可以设置为固定值。在本公开的一个实施例之中，基站配置的值可大于协议为轻型UE规定的预设值
步骤703，根据跳频次数进行跳频。
UE根据以上步骤确定的跳频次数进行跳频。
在本公开的实施例之中，可以对轻型UE的跳频次数进行调整，从而避免轻型UE出现跳出系统带宽范围的问题。
图8为本公开实施例提供的一种跳频控制方法的流程示意图，由轻型UE执行，需要说明的是，在本公开的实施例中，跳频参数包括跳频偏移值、跳频次数和跳频时域粒度，其中，跳频偏移值，用于确定每一跳的起始位置；跳频次数，用于通过配置多个频域位置，可以获得更高的频率分集增益，跳频时域粒度，用于通过扩展时域跳频的基本粒度,可以支持实现Cross-slot(跨时隙)联合信道估计，或者针对低流动性或静止UE,降低其DMRS(Demodulation Reference Signal，解调参考信号)密度等。
如图8示，在该实施例之中，可通过射频重调的方式进行调整。该跳频控制方法包括以下步骤：
步骤801，确认轻型UE下一跳的位置。
如图9a所示，为本公开实施例的进行射频重调的一个示意图。参照图9a所示，轻型UE的下一跳时域位置为Slot3。
步骤802，如果下一跳的频域位置超出轻型UE当前工作带宽所在的频域位置，则进行射频重调，以使轻型UE的工作带宽跳转至下一跳所在频域位置。
进一步参照图9a所示，轻型UE的下一跳频域位置超出了轻型UE当前工作带宽所在的频域位置。因此，需要对轻型UE进行射频重调，以使轻型UE的工作带宽跳转至下一跳所在频域位置，例如图9a之中的Slot4。
在本公开的实施例中，射频重调的时间间隔由协议规定为固定值，或基站指示。
在本公开的实施例中，时间间隔由系统消息、媒体接入控制控制单元MAC CE或DCI信令指示。
如图9b所示，为本公开实施例的进行射频重调的另一个示意图。轻型UE从Hop#0，通过射频重调的方式跳转至Hop#1。
在本公开的实施例之中，对于时隙内跳频，如果采用本公开实施例的射频重调方案，对于PUSCH时域资源分配，可使得射频重调时间+PUSCH字符数<＝预设字符数，例如14。
在上述实施例之中，当轻型UE和非轻型UE共用BWP时，本公开实施可支持轻型UE和非轻型UE的Msg3传输支持跳频机制，包括传统的时隙内跳频、时隙间跳频和多跳时隙间跳频,以及时域粒度增强的时隙间跳频方案。
图10为本公开实施例提供的一种跳频控制方法的流程示意图，由基站执行，以在UE在确定跳频偏移值、跳频次数和跳频时域粒度等跳频参数后，可以按照确定的跳频参数进行跳频。需要说明的是，在本公开的实施例中，跳频参数包括跳频偏移值、跳频次数和跳频时域粒度，其中，跳频偏移值，用于确定每一跳的起始位置；跳频次数，用于通过配置多个频域位置，可以获得更高的频率分集增益，跳频时域粒度，用于通过扩展时域跳频的基本粒度,可以支持实现Cross-slot(跨时隙)联合信道估计，或者针对低流动性或静止UE,降低其DMRS(Demodulation Reference Signal，解调参考信号)密度等。
如图10所示，该跳频控制方法包括以下步骤：
步骤1010，确定UE的类型。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。在LTE 4G系统中，为了支持物联网业务提出了MTC(机器类通信，Machine Type Communications)，NB-IoT(窄带物联网)两大技术。这两大技术主要针对的是低速率，高时延等场景，比如抄表，环境监测等场景。NB-IoT目前最大只能支持几百k的速率，MTC目前最大只能支持几M的速率。但同时另外一方面，随着物联网业务的不断发展，比如视频监控，智能家居，可穿戴设备和工业传感监测等业务的普及。这些业务通常要求几十到100M的速率，同时对时延也有相对较高的要求，因此LTE中的MTC,NB-IoT技术很难满足要求。在该实施例之中，将这种新的UE类型统称为Reduced capability UE，即轻型UE，而目前的普通终端，在本公开的实施例之中称之为非轻型UE。
在本公开的一个实施例之中，通常轻型UE具有以下特点：
-低造价，低复杂度
-一定程度的覆盖增强
-功率节省。
由于目前的NR新空口是针对高速率低时延等高端终端设计的，因此当前的设计无法满足轻型UE的上述要求。因此需要对目前的NR系统进行改造用以满足轻型UE的要求。比如，为了满足低造价，低复杂度等要求，可以限制轻型UE的带宽，比如限制到10M Hz或者20M Hz,或者限制轻型UE的接收天线数量。针对功率节省，可能的优化方向是减少用户设备的处理复杂度，如在同一个时隙中只接收PDCCH(物理下行控制信道，Physical Downlink Control Channel)信道，在同一时隙的其他符号时刻则进入微睡眠状态。对于一定程度的覆盖增强，还可对各个信道进行多次重复传输，增加聚合等级以及降低码率等。
在本公开的一个实施例中，可根据带宽的大小，确定UE类型。在本公开的一个实施例之中，基站可以获知UE的带宽，根据UE的带宽大小，可以获知该UE的类型，即轻型UE或非轻型UE。在本公开的其他实施例之中，还可根据物理随机接入信道(physical random accesschannel，PRACH)对两种UE的类型进行区分。
如图2所示，在本公开的一个实施例中，跳频偏移值用于确定每一跳的起始位置；跳频次数可理解为跳频的跳数：比如Message3重复传输8次，跳频时域粒度是1个slot，跳数可以为4，那么跳频模式可如图2所示，其中，也就是说，在repetition过程中，msg3的传输有4个不同的频域位置(如图2之中的灰色部分)。
步骤1020，根据UE的类型确定UE的跳频参数。
在本公开的实施例之中，跳频参数包括跳频起始位置、跳频偏移量以及跳频次数之中的一个或多个。在本公开的一个实施例之中，跳频参数是根据UE的类型来决定的。具体而言，可以为轻型UE设置独立的跳频参数，并为非轻型UE设置独立的跳频参数，使得轻型UE和非轻型UE的跳频参数有所区别，从而避免轻型UE在跳频时出现跳出轻型UE系统带宽的情况。在本公开的另一个是实施例之中，也还可以为轻型UE和非轻型UE设置相同的跳频参数，该跳频参数需要兼顾轻型UE，避免其跳出轻型UE的系统带宽范围的情况。或者，还可以保持目前非轻型UE的跳频参数不变，对轻型UE的跳频参数进行调整。
步骤1030，根据确定的UE的跳频参数为UE提供跳频服务。
在本公开的实施例中，可以根据确定UE的跳频参数为UE提供跳频服务。
图11为本公开实施例提供的一种跳频控制方法的流程示意图，由基站执行。需要说明的是，在本公开的实施例中，跳频参数包括跳频偏移值、跳频次数和跳频时域粒度，其中，跳频偏移值，用于确定每一跳的起始位置；跳频次数，用于通过配置多个频域位置，可以获得更高的频率分集增益，跳频时域 粒度，用于通过扩展时域跳频的基本粒度,可以支持实现Cross-slot(跨时隙)联合信道估计，或者针对低流动性或静止UE,降低其DMRS(Demodulation Reference Signal，解调参考信号)密度等。
如图11所示，在该实施例之中，跳频参数可为跳频起始位置。该跳频控制方法包括以下步骤：
步骤1110，确定UE的类型。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。
其中，在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。在LTE 4G系统中，为了支持物联网业务提出了MTC(机器类通信，Machine Type Communications)，NB-IoT(窄带物联网)两大技术。这两大技术主要针对的是低速率，高时延等场景，比如抄表，环境监测等场景。NB-IoT目前最大只能支持几百k的速率，MTC目前最大只能支持几M的速率。但同时另外一方面，随着物联网业务的不断发展，比如视频监控，智能家居，可穿戴设备和工业传感监测等业务的普及。这些业务通常要求几十到100M的速率，同时对时延也有相对较高的要求，因此LTE中的MTC,NB-IoT技术很难满足要求。在该实施例之中，将这种新的UE类型统称为Reduced capability UE，即轻型UE，而目前的普通终端，在本公开的实施例之中称之为非轻型UE。
在本公开的一个实施例之中，通常轻型UE具有以下特点：
-低造价，低复杂度
-一定程度的覆盖增强
-功率节省。
由于目前的NR新空口是针对高速率低时延等高端终端设计的，因此当前的设计无法满足轻
型UE的上述要求。因此需要对目前的NR系统进行改造用以满足轻型UE的要求。比如，为了满足低造价，低复杂度等要求，可以限制轻型UE的带宽，比如限制到10M Hz或者20M Hz,或者限制轻型UE的接收天线数量。针对功率节省，可能的优化方向是减少用户设备的处理复杂度，如在同一个时隙中只接收PDCCH(物理下行控制信道，Physical Downlink Control Channel)信道，在同一时隙的其他符号时刻则进入微睡眠状态。对于一定程度的覆盖增强，还可对各个信道进行多次重复传输，增加聚合等级以及降低码率等。
在本公开的一个实施例中，可根据带宽的大小，确定UE类型。在本公开的一个实施例之中，基站可以获知UE的带宽，根据UE的带宽大小，可以获知该UE的类型，即轻型UE或非轻型UE。在本公开的其他实施例之中，还可根据物理随机接入信道(physical random accesschannel，PRACH)对两种UE的类型进行区分。
如图2所示，在本公开的一个实施例中，跳频偏移值用于确定每一跳的起始位置；跳频次数可理解为跳频的跳数：比如Message3重复传输8次，跳频时域粒度是1个slot，跳数可以为4，那么跳频模式可如图2所示，其中，也就是说，在repetition过程中，msg3的传输有4个不同的频域位置(如图2之中的灰色部分)。
步骤1120，根据UE的类型确定UE跳频参数为跳频起始位置。
在本公开的一个实施例之中，对于非轻型UE和轻型UE可以通过相同的方式确定跳频起始位置。但是对于轻型UE而言，在确定了轻型UE的跳频起始位置之后，需要对轻型UE的跳频起始位置进行调整，使其减小，从而避免跳出轻型UE的系统带宽范围的情况发生。
在本公开的一个实施例中，可通过以下方式确定跳频参数为跳频起始位置。
其中，响应于UE为轻型UE，确定UE的起始跳频初始位置，然后根据UE的起始跳频初始值确定UE的跳频起始位置。
其中，调整值，通过以下方式确定：协议规定；或者，向UE发送信令配置。
在本公开的一个实施例之中，调整值可以通过协议的方式固定，也可以由基站进行动态配置。
在本公开的实施例中，确定UE的系统带宽，响应于起始跳频初始位置超出UE的系统带宽，获取调整值，之后根据调整值对起始跳频初始位置进行调整，以生成UE的跳频起始位置。
其中，在本公开的实施例中，响应于起始跳频初始位置未超出UE的系统带宽，将起始跳频初始位置确定为UE的跳频起始位置。
在本公开的一个实施例之中，例如确定的起始跳频初始位置为n，且该n出现了跳出轻型UE系统带宽的问题，则需要对n进行调整。在本公开的另一个实施例之中，例如确定第n跳的的起始跳频初始位置为a，且a跳出了轻型UE所支持的最大系统带宽，那么第n跳的跳频起始位置可以为第n-m跳的 位置b，其中b在轻型UE系统带宽范围内，并且，n>m。在该实施例之中，m可以通过协议固定，也可以是由基站动态配置。m依据跳频次数决定。
如图4所示为，本公开实施例的跳频起始位置调整示意图。如图4所示，在Slot3(时隙3)时，由于出现超出UE系统带宽的情况，因此对其进行调整，例如减去调整值，例如2，使其回落到轻型UE的系统带宽之中。同样地，对于Slot4而言，也可对其减去调整值，例如2。
其中，在本公开的一个实施例中，响应于UE为非轻型UE，则将起始跳频初始位置作为跳频起始位置。
在本公开的实施例中，基站可通过向UE发送信令告知UE的调整值。在本公开的一个实施例之中，信令可包括剩余最小系统消息RMSI(Remaining Minimum System Information)信令。
在本公开的实施例中，通过获取UE的当前跳频次数，根据当前跳频次数生成UE的当前跳频起始位置，根据UE的类型生成调整系数，以及根据调整系数和当前跳频起始位置生成UE的跳频起始位置。
在本公开的实施例之中，对于UE而言，可以将
Figure PCTCN2021072350-appb-000025
作为当前跳频起始位置，其中，i为当前跳频次数，RBstart为当前跳频起始位置，RBoffset为偏移量。
其中，在本公开的实施例中，如果UE为非轻型UE，则获取非轻型UE的带宽部分BWP，并根据BWP生成调整系数；如果UE为轻型UE，则获取轻型UE的系统带宽，并根据系统带宽生成调整系数。
在本公开的一个实施例之中，对于非轻型UE而言，该调整系数为
Figure PCTCN2021072350-appb-000026
其中，
Figure PCTCN2021072350-appb-000027
为非轻型UE的带宽部分BWP。
在本公开的一个实施例之中，对于轻型UE而言，可根据轻型UE的系统带宽生成该调整系数。在本公开的另一个实施例之中，对于轻型UE而言，该调整系数为
Figure PCTCN2021072350-appb-000028
其中，
Figure PCTCN2021072350-appb-000029
为非轻型UE的带宽部分BWP，
Figure PCTCN2021072350-appb-000030
为轻型UE的系统带宽。
在本公开的实施例中，基于取模生成的调整系数，还可基于其它方式生成调整系数，对此本公开不作任何限制。
在本公开的实施例中，根据系统带宽生成调整系数的实现方式可为，根据轻型UE的系统带宽和非轻型UE的BWP之中的最小值生成调整系数。
在本公开的实施例中，根据非轻型UE的BWP和轻型UE的系统带宽之中的最小值生成调整系数，其中，非轻型UE和轻型UE的跳频起始位置均通过该调整系数确定。
步骤1130，根据UE的类型确定UE跳频参数为跳频偏移量。
在本公开的实施例中，向UE发送UE的类型所对应的偏移量配置表，向UE发送偏移量标识。
其中，偏移量配置表，通过以下方式确定：协议规定；或者，向UE发送信令配置。
在本公开的一个实施例之中，针对UE不同的类型，设置不同的偏移量配置表。
在本公开的一个实施例之中，可以为非轻型UE和轻型UE配置相同的偏移量配置表，也可以为非轻型UE和轻型UE配置不相同的偏移量配置表。在配置相同的偏移量配置表，可避免轻型UE跳出自身系统带宽。
在本公开的实施例中，如果UE为非轻型UE，则非轻型UE对应的第一偏移量配置表之中的跳频偏移量根据非轻型UE的BWP确定；如果UE为轻型UE，则轻型UE对应的第二偏移量配置表之中的跳频偏移量根据轻型UE的系统带宽确定。
其中，第二偏移量配置表之中的跳频偏移量根据轻型UE的系统带宽和非轻型UE的BWP之中的最小值确定。
在本公开的一个实施例中，非轻型UE和轻型UE均使用第二偏移量配置表。
在本公开的实施例中，非轻型UE对应的跳频偏移量由非轻型UE的BWP确定，轻型UE对应的跳频偏移量由非轻型UE的BWP和轻型UE的系统带宽之中的最小值确定。
步骤1140，根据UE的类型确定UE跳频参数为跳频次数。
在本公开的实施例中，如果UE为非轻型UE，则将第一跳频次数作为非轻型UE的跳频次数；如果UE为轻型UE，则将第二跳频次数作为轻型UE的跳频次数，其中，第一跳频次数大于第二跳频次数。
其中，非轻型UE支持的跳频次数大于轻型UE支持的跳频次数。
其中，第一跳频次数和第二跳频次数由协议配置或者基站指示。
其中，第一跳频次数和第二跳频次数，通过基站的RMSI、随机接入响应RAR或下行控制信息DCI指示。
在本公开的一个实施例中，判断非轻型UE的BWP是否大于轻型UE的系统带宽，如果大于轻型UE的系统带宽，则将第一预设次数作为非轻型UE的跳频次数，并将第二预设次数作为轻型UE的跳频次数，其中，第一预设次数大于第二预设次数；如果小于或等于轻型UE的系统带宽，则将第一预设次数作为非轻型UE和轻型UE的跳频次数。
在本公开的一个实施例中，通过发送第一指示次数和第二指示次数，其中，第一指示次数大于第二指示次数，其中，如果非轻型UE的BWP大于轻型UE的系统带宽，则将第一指示次数作为非轻型UE的跳频次数，并将第二指示次数作为轻型UE的跳频次数。
在本公开的一个实施例中，发送第三指示次数，其中，如果非轻型UE的第一BWP小于或等于轻型UE的第二BWP，则将第三指示次数作为非轻型UE和轻型UE的跳频次数
需要说明的是，上述第一指示次数和第二指示次数，或者第三指示次数，通过基站的RMSI、随机接入响应RAR或下行控制信息DCI指示。
在本公开个一个实施例之中，也还可为轻型UE通知或设置预设的值，例如0，即对轻型UE来说不进行跳频。
在本公开的实施例中，非轻型UE对应的跳频次数由基站指示，轻型UE的对应的跳频次数由协议规定。
步骤1050，根据确定跳频起始位置、跳频偏移量和跳频次数，为UE提供跳频服务。
在本公开的实施例中，确定跳频起始位置之后，可按照确定之中的跳频起始位置进行跳频服务。
在该实施例之中，可根据UE的类型，确定调整系数，从而使得轻型UE，避免跳出轻型UE的系统带宽范围。
在本公开的一个实施例之中，对于多个跳频位置的方式，可以通过以下方式确定轻型UE和非轻型UE的跳频起始位置。
对于非轻型UE而言，可以通过以下公式计算跳频起始位置：

其中，i为跳频次数。
对于轻型UE而言，可以通过以下公式计算跳频起始位置：

其中，i为跳频次数。
在本公开的另一个实施例之中，对于时隙内跳频(intra-slot)以及两跳时隙间跳频(inter-slot)的方式，还可通过以下公式来确定跳频起始位置。
对于非轻型UE，以及时隙内跳频(intra-slot)而言，可通过以下公式确定跳频起始位置：
Figure PCTCN2021072350-appb-000033
对于非轻型UE，以及两跳时隙间跳频(inter-slot)而言，可通过以下公式确定跳频起始位置：

其中，i为跳频次数。
在本公开的其他实施例之中，还可以进行多次的跳频，例如对于轻型UE而言，可以通过以下公式确定跳频起始位置：

Figure PCTCN2021072350-appb-000038
其中，i为跳频次数。
对于轻型UE的两跳时隙间跳频：
Figure PCTCN2021072350-appb-000039
Figure PCTCN2021072350-appb-000040
为当前时隙号。
在上述实施例之中，可以用于轻型UE支持RAR和Msg3之间进行RFretuning(射频重调)的场景中。
在本公开的事实中，确定跳频偏移量之后，按照跳频偏移量进行跳频服务。
其中，在本公开的实施例之中，可以对轻型UE的跳频偏移量进行调整，从而避免轻型UE出现跳出系统带宽范围的问题。
在本公开的一个实施例之中，当UE为非轻型UE，则非轻型UE对应的第一偏移量配置表之中的跳频偏移量根据非轻型UE的BWP确定；当UE为轻型UE，则轻型UE对应的第二偏移量配置表之中的跳频偏移量根据轻型UE的系统带宽确定。
在该实施例之中，对于时隙内跳频(intra-slot)，非轻型UE可以使用如下的第一偏移量配置表：
Figure PCTCN2021072350-appb-000041
Figure PCTCN2021072350-appb-000042
表1
在该实施例之中，对于时隙内跳频(intra-slot)，轻型UE可以使用如下的第二偏移量配置表：
Figure PCTCN2021072350-appb-000043
表2
在本公开的一个实施例之中，上述表1和表2可通过协议的方式固定。也可通过基站指示的方式配置到UE之中。
在本公开的其他实施例之中，对于两跳的时隙间跳频，非轻型UE可以使用如下的第一偏移量配置表：
Figure PCTCN2021072350-appb-000044
表3
在本公开的其他实施例之中，对于两跳的时隙间跳频，轻型UE可以使用如下的第二偏移量配置表：
Figure PCTCN2021072350-appb-000045
表4
其中，在本公开的一个实施例中，在偏移量配置表之中，非轻型UE对应的跳频偏移量由非轻型UE的BWP确定，轻型UE对应的跳频偏移量由非轻型UE的BWP和轻型UE的系统带宽之中的最小值确定。
在本公开的一个实施例之中，还可通过系统消息给UE配置上述偏移量配置表。
在本公开的实施例之中，非轻型UE和轻型UE可均使用第二偏移量配置表。
在本公开的一个实施例之中，还可以针对多跳设置偏移量配置表。
在本公开的其他实施例之中，对于三跳的时隙间跳频，非轻型UE可以使用如下的第一偏移量配置表：
Figure PCTCN2021072350-appb-000046
表5
在本公开的其他实施例之中，对于三跳的时隙间跳频，轻型UE可以使用如下的第二偏移量配置表：
Figure PCTCN2021072350-appb-000047
表6
在本公开的实施例之中，上述第一偏移量配置表5和第二偏移量配置表6可通过协议规定，也可以通过系统消息通知。
在本公开的实施例之中，还将第一偏移量配置表和第二偏移量配置表合并。该合并之中的表对于轻型UE和非轻型UE均适用，如下表所示。
Figure PCTCN2021072350-appb-000048
表7
在本公开的一个实施例中，可将多个跳频偏移值配置表汇总至一个大表中，之后再将第一偏移量标识作为索引值进行检索。由于将多个跳频偏移值配置表汇总至一个表中，导致该大表较长，因此相应动态信令中需要扩展比特位来指示其索引。其中，扩展的比特位可复用RARULgrant中的TPC(功控)字段。
在本公开的一个实施例中，当需要进行重复时，此时覆盖较差，终端一般使用满功率发送，此时TPC(功控)字段无效，因此可以复用该TPC字段作为扩展的比特位(即第一偏移量标识)。
在本公开的一个实施例之中，基站可以设置第一偏移量配置表和第二偏移量配置表，或者，也可以设置第一偏移量配置表或第二偏移量配置表。如果BWP大于轻型UE的系统带宽，则在基站之中配置第一偏移量配置表和第二偏移量配置表。如果BWP小于或等于轻型UE的系统带宽，则在基站之中只配置第一偏移量配置表，轻型UE也使用该第一偏移量配置表。
在本公开的一个实施例之中，基站可以设置第一偏移量配置表和第二偏移量配置表，非轻型UE使用第一偏移量配置表进行跳频起始位置的确定，轻型UE使用第二偏移量配置表进行跳频起始位置的确定。
在本公开的一个实施例之中，如果上述偏移量配置表由系统消息通知，则在该实施例之中可以只发送第二偏移量配置表，非轻型UE和轻型UE均使用第二偏移量配置表进行跳频起始位置的确定。这样基站可以无需对UE进行类型区分。
在本公开的一个实施例之中，偏移量不仅可以通过上述的偏移量配置表设定，还可以通过协议设定，或者基站的系统消息配置。
在本公开的事实中，在UE确定了跳频次数之后，按照跳跳频次数进行跳频。
在本公开的实施例之中，可以对轻型UE的跳频次数进行调整，从而避免轻型UE出现跳出系统带宽范围的问题。
与上述几种实施例提供的跳频控制方法相对应，本公开还提供一种跳频控制装置，由于本公开实施例提供跳频控制装置与上述几种实施例提供的跳频控制方法相对应，因此在跳频控制方法的实施方式也适用于本实施例提供的跳频控制装置，在本实施例中不再详细描述。图12-图14是根据本公开提出的跳频控制装置的结构示意图。
图12为本公开实施例提供的跳频控制装置的结构示意图。所述装置应用于用户设备UE。
如图12所示，该跳频的控制装置1200包括：第一确定模块1201、第二确定模块1202和第一处理模块1203，其中：
第一确定模块1201，被配置为确定UE的类型。在本公开的实施例之中，UE的类型包括轻型UE(Reduced capability)和非轻型UE。在本公开的一个实施例中，轻型UE可理解为带宽较小或者天线数量较少的物联网设备，非轻型UE可理解为支持NR全部特性的普通NR终端。在本公开的一个实施例中，可根据带宽的大小，确定UE类型。在本公开的一个实施例之中，基站可以获知UE的带宽，根据UE的带宽大小，可以获知该UE的类型，即轻型UE或非轻型UE。在本公开的其他实施例之中，还可根据物理随机接入信道(physical random accesschannel，PRACH)对两种UE的类型进行区分。
第二确定模块1202，被配置为根据UE的类型确定跳频参数。在本公开的实施例之中，跳频参数包括跳频起始位置、跳频偏移量以及跳频次数之中的一个或多个。在本公开的一个实施例之中，跳频参数是根据UE的类型来决定的。具体而言，可以为轻型UE设置独立的跳频参数，并为非轻型UE设置独立的跳频参数，使得轻型UE和非轻型UE的跳频参数有所区别，从而避免轻型UE在跳频时出现跳出轻型UE系统带宽的情况。在本公开的另一个是实施例之中，也还可以为轻型UE和非轻型UE设置相同的跳频参数，该跳频参数需要兼顾轻型UE，避免其跳出轻型UE的系统带宽范围的情况。或者，还可以保持目前非轻型UE的跳频参数不变，对轻型UE的跳频参数进行调整。
第一处理模块1203，被配置为根据确定的跳频参数进行跳频。在本公开的实施例之，可以根据UE确定的跳频参数进行跳频。例如根据跳频起始位置、跳频偏移量以及跳频次数进行跳频。
在本公开的实施例之中，可以根据UE的类型对跳频参数进行调整，从而避免跳出轻型UE的系统带宽范围的情况发生。
本公开的一个实施例中，跳频参数为跳频起始位置。
本公开的一个实施例中，第二确定模块1202，被配置为响应于所述UE为轻型UE，确定所述UE的起始跳频初始位置；根据所述起始跳频初始值确定跳频起始位置。
在本公开的一个实施例之中，例如确定的起始跳频初始位置为n，且该n出现了跳出轻型UE系统带宽的问题，则需要对n进行调整。在本公开的另一个实施例之中，例如确定第n跳的的起始跳频初始位置为a，且a跳出了轻型UE所支持的最大系统带宽，那么第n跳的跳频起始位置可以为第n-m跳的 位置b，其中b在轻型UE系统带宽范围内，并且，n>m。在该实施例之中，m可以通过协议固定，也可以是由基站动态配置。m依据跳频次数决定。
其中，在本公开的一个实施例中，响应于起始跳频初始位置未超出UE的系统带宽，可直接将起始跳频初始位置确定为跳频起始位置。
如图4所示为，本公开实施例的跳频起始位置调整示意图。如图4所示，在Slot3(时隙3)时，由于出现超出UE系统带宽的情况，因此对其进行调整，例如减去调整值，例如2，使其回落到轻型UE的系统带宽之中。同样地，对于Slot4而言，也可对其减去调整值，例如2。
本公开的一个实施例中，所述第二确定模块1202，被配置为确定所述UE的系统带宽；响应于起始跳频初始位置超出所述UE的系统带宽，获取调整值，并根据所述调整值对所述起始跳频初始位置进行调整，以生成所述跳频起始位置。
本公开的一个实施例中，所述第二确定模块1202，被配置为响应于起始跳频初始位置未超出所述UE的系统带宽，将所述起始跳频初始位置确定为所述跳频起始位置。
本公开的一个实施例中，所述调整值，通过以下方式确定：协议规定；或者，通过基站发送的信令配置。
本公开的一个实施例中，所述第二确定模块1202，被配置为响应于所述UE为非轻型UE，则将所述起始跳频初始位置作为所述跳频起始位置。
本公开的一个实施例中，所述第二确定模块1202，包括：获取跳频次数单元，被配置为获取当前跳频次数；生成当前跳频起始位置单元，被配置为根据所述当前跳频次数生成当前跳频起始位置；生成调整系数单元，被配置为根据所述UE的类型生成调整系数；以及生成跳频起始位置单元，被配置为根据所述调整系数和所述当前跳频起始位置生成所述跳频起始位置。
在本公开的实施例之中，对于UE而言，可以将
Figure PCTCN2021072350-appb-000049
作为当前跳频起始位置，其中，i为当前跳频次数，RBstart为当前跳频起始位置，RBoffset为偏移量。
在本公开的一个实施例之中，对于非轻型UE而言，该调整系数为

其中，
Figure PCTCN2021072350-appb-000051

其中，

为非轻型UE的带宽部分BWP，
Figure PCTCN2021072350-appb-000054
为轻型UE的系统带宽。
在本公开的实施例中，基于取模生成的调整系数，还可基于其它方式生成调整系数，对此本公开不作任何限制。
在本公开的一个实施例之中，对于多个跳频位置的方式，可以通过以下方式确定轻型UE和非轻型UE的跳频起始位置。
对于非轻型UE而言，可以通过以下公式计算跳频起始位置：

其中，i为跳频次数。
对于轻型UE，以及两跳时隙间跳频(inter-slot)而言，可通过以下公式确定跳频起始位置：
Figure PCTCN2021072350-appb-000060
其中，i为跳频次数。
在本公开的其他实施例之中，还可以进行多次的跳频，例如对于轻型UE而言，可以通过以下公式确定跳频起始位置：
对于轻型UE基于时隙间跳频的多次跳频：

在上述实施例之中，可以用于轻型UE支持RAR和Msg3之间进行RFretuning(射频重调)的场景中。
在本公开的实施例之中，根据所述轻型UE的系统带宽和非轻型UE的BWP之中的最小值生成调整系数。在本公开的另一个实施例之中，轻型UE和非轻型UE均使用相同的跳频起始位置确定公式。在该实施例之中，由于轻型UE和非轻型UE使用的公式相同(均采用如上所示的轻型UE的跳频起始位置确定 公式)，因此基站无需对二者进行区分。在本公开的另一个实施例之中，根据非轻型UE的BWP和轻型UE的系统带宽之中的最小值生成调整系数，其中，非轻型UE和轻型UE的跳频起始位置均通过该调整系数确定。
本公开的一个实施例中，所述生成调整系数单元，包括：调整系数生成子单元，被配置为如果UE为非轻型UE，则获取非轻型UE的带宽部分BWP，并根据BWP生成调整系数；如果UE为轻型UE，则获取轻型UE的系统带宽，并根据系统带宽生成调整系数。
本公开的一个实施例中，获取系统带宽子单元，被配置为根据轻型UE的系统带宽和非轻型UE的BWP之中的最小值生成所述调整系数。

本公开的一个实施例中，跳频参数为跳频偏移量。
本公开的一个实施例中，第二确定模块1202，包括：获取偏移量配置表单元，被配置为获取UE的类型所对应的偏移量配置表；获取偏移量标识单元，被配置为获取基站指示的偏移量标识；确定跳频偏移量单元，被配置为根据偏移量标识和UE的类型所对应的偏移量配置表确定跳频偏移量。
在本公开的一个实施例中，可首先通过获取UE的类型所对应的偏移量配置表，之后获取基站指示的偏移量标识，再根据偏移量标识和UE的类型所对应的偏移量配置表确定跳频偏移量。
在本公开的一个实施例之中，针对UE不同的类型，设置不同的偏移量配置表。
在本公开的一个实施例之中，偏移量配置表可以是协议规定的，也可以是基站通过系统消息通知的。
在本公开的一个实施例之中，可以为非轻型UE和轻型UE配置相同的偏移量配置表，也可以为非轻型UE和轻型UE配置不相同的偏移量配置表。在配置相同的偏移量配置表，可避免轻型UE跳出自身系统带宽。
