Description

数据传输方法、装置、用户设备、网络设备及存储介质
本申请要求于2021年1月26日提交中国专利局、申请号为CN202110106501.8、名称为“数据传输方法、装置、用户设备、网络设备及存储介质”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领域，具体涉及一种数据传输方法、装置、用户设备、网络设备及存储介质。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)协议中，用户设备(User Equipment，UE)分为轻量UE(Reduced Capability UE，RedCap UE)及非轻量UE(non Reduced Capability UE，non-RedCap UE)。non-RedCap UE包括增强移动宽带(eMBB)UE及超可靠低延迟通信(URLLC)UE。
在实际应用中，RedCap UE及non-RedCap UE可能接入同一小区。具体随机接入过程中，UE在传输部分消息时，为获得频率分集增益，可在时隙内跳频。由于non-RedCap UE支持的最大带宽为100MHz，初始上行BWP可配置的最大带宽为100MHz，因此，初始上行BWP很有可能会超过RedCap UE本身所支持的最大带宽20MHz。对于RedCap UE，当没有配置专用的初始上行BWP，RedCap UE和non-RedCap UE共用初始UL BWP时，且初始上行BWP可能超过20MHz时，UE在时隙内跳频时，根据现有协议的要求，两跳之间频率间隔将大于RedCap UE支持的最大带宽，导致两跳之间RedCap UE需要调整中心频点，需要一定的时间进行射频调频。
然而，根据现有协议要求，UE在时隙内跳频时，相邻两跳之间在时间上应是连续的，导致UE没有时间进行射频调频。
在实际应用中，网络可以为RedCap UE配置一个专门的初始上行BWP，以完成时隙内跳频传输数据。
然而，当网络不为RedCap UE配置一个专门的初始上行BWP时，如何完成时隙内跳频传输数据，成为亟待解决的问题。

具体实施方式
图1示出了本申请实施例提供的数据传输方法适用的一种可能的通信系统，所述通信系统的架构包括：基站和多个用户设备(如图中所示的用户设备1、用户设备2、用户设备3和用户设备4)。其中：
所述基站，用于为所述基站控制的小区中的用户设备提供无线接入服务。例如， 图1所示，所述基站控制小区1和小区2，分别为所述小区1中的用户设备(如图1中的用户设备1和用户设备2)和所述小区2中的用户设备(如图1中的用户设备3和用户设备4)提供无线接入服务。

具体的，所述多个用户设备需要通过随机接入流程与所述基站建立连接，以使所述多个用户设备实现通过接入所述基站进行数据业务。
需要说明的是，图1所示的通信系统仅仅作为一个示例，不限于包括图1中所示的基站和多个用户设备。所述通信系统还可以包括多个基站，以及其它设备，具体此处不再列举。
在实际应用中，对于待传输数据，为获得频率分集增益，UE可以进行时隙内跳频，比如，在基于竞争或非竞争的随机接入过程中。可以理解的是，在其它情形或场景中进行上行传输时，也可能需要进行时隙内跳频，具体应用场景不作限定。
下面分别以基于竞争随机接入过程和基于非竞争的随机接入过程为例，对本申请中数据传输方法进行详细描述。
图2为一种四步随机接入过程中UE与基站gNB之间的信令交互示意图。具体随机接入过程如下：
步骤101，UE向gNB发送随机接入请求Msg1。
随机接入请求(Random Access Preamble)，即Msg1。在具体实施中，随机接入请求Msg1包含随机接入前导(random access preamble)码。
步骤102，gNB向UE发送随机接入响应Msg2。
随机接入响应(Random Access Response)即Msg2是基站在接收到随机接入请求Msg1后的响应消息。
步骤103，UE向gNB发送无线资源控制连接请求Msg3。
无线资源控制连接请求(Scheduled Transmission)，即Msg3。
所述无线资源控制连接请求Msg3中包括需要传输的PUSCH。
步骤104，UE接收无线资源控制建立Msg4。
无线资源控制建立(Contention Resolution)，即Msg4。无线资源控制建立Msg4中包含所述UE的标识，用于通知所述UE随机接入成功。
在具体实施中，UE接收无线资源控制建立Msg4后，会向基站反馈上行控制信息，以告知基站是否正确收到无线资源控制建立Msg4。所述下行控制信通过物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)发送至UE，为了描述方便，本申请实施例中用于向基站反馈是否正确收到无线资源控制建立Msg4的上行控制信息，简称为PUCCH。
在图2示出的随机接入过程中，UE在发送随机接入消息Msg3，对于其中需要传输的PUSCH，UE可采用时隙内跳频的方式，完成数据发送。UE收到冲突解决消息Msg4 后反馈上行控制信息时，也可采用时隙内跳频的方式，完成PUCCH的发送。
图3为两步随机接入过程中UE与基站gNB之间的信令交互示意图。
具体随机接入过程如下：
步骤201，UE向gNB发送第一消息MsgA。
所述第一消息MsgA中包括随机接入前导码信息及需要传输的PUSCH。UE先向gNB发送随机接入前导码，然后再发送需要传输的PUSCH。
步骤202，gNB向UE发送第二消息MsgB。
所述第二消息MsgB可以包括随机接入前导的序列编号、小区无线网络临时标识和接入成功的UE标识。
在图3示出的随机接入过程中，UE在发送第一消息MsgA时，对于其中需要传输的PUSCH，UE可采用时隙内跳频的方式，完成数据传输。
所谓时隙内跳频，是指一个传输块，拆分成多个部分，分别在同一信道的多个频域位置上发送。其中，该传输块的时域资源位于一个时隙内，每部分数据对应的频域位置不同，每个频域位置发送的是该传输块的一部分。
该传输块被拆分N部分，时隙内跳频可以分为N跳，N≥2且为正整数。例如，将一个传输块分为两部分，分别在同一信道上的两个不同频域位置发送，则时隙内跳频的模式是两跳。将该传输块的其中一部分称为该传输块的第一跳，另一部分称为该传输块的第二跳。
现有协议中规定，当需要进行时隙内跳频传输时，相邻两跳之间在时间上应是连续的，即并未额外配置时域资源供UE进行射频调频。
以N＝2为例，所谓相邻两跳之间在时间上连续是指：基站配置的用于传输该传输块的时域资源中，该传输块第一跳的结束时刻，即该传输块第二跳的起始时刻，或者，该传输块第二跳的结束时刻，即该传输块第一跳的起始时刻。
在实际应用中，网络可以为RedCap UE配置一个专门的初始上行BWP，以完成时隙内跳频传输数据。
然而，由于non-RedCap UE支持的最大带宽为100MHz，初始上行BWP可配置的最大带宽为100MHz，因此，初始上行BWP很有可能会超过RedCap UE本身所支持的最大带宽20MHz。此时，对于RedCap UE，若没有配置专用的初始上行BWP，RedCap UE和non-RedCap UE共用初始UL BWP时，UE在传输无线资源控制连接请求Msg3、第一消息MsgA中的PUSCH或反馈无线资源控制建立Msg4是否正确接收的PUCCH时，若需要时隙内跳频，则两跳之间的频率间隔可能大于RedCap UE支持的最大带宽，导致RedCap UE在两跳之间需要调整中心频点，即需要一定的时间进行射频(Radio Frequency，RF)调频(retuning)，来将当前中心频点调整至下一跳的中心频点(即射频调频)后，才能进行时隙内跳频传输数据。
当网络不为RedCap UE配置一个专门的初始上行BWP时，如何完成时隙内跳频传输数据，成为亟待解决的问题。
针对该问题，本申请提供了一种数据传输方法，用户设备在基于所述频域资源配置信息，确定用于传输第一数据的频域资源时，控制传输第一数据的第一资源和第二 资源在频域上的总带宽小于或等于用户设备所支持的最大带宽，或者，传输第一数据的第一资源和第二资源在时域上的间隔大于或等于用于射频调频的时长用户设备，完成了时隙内跳频传输数据。
为使本申请的上述目的、特征和优点能够更为明显易懂，下面结合附图对本申请的具体实施例作详细地说明。
实施例1
参照图4，本申请实施例提供了一种数据传输方法，所述方法可以包括如下步骤：
步骤31，接收用于传输第一数据的资源配置信息；所述资源配置信息配置的时域资源位于一个时隙内。
在具体实施中，所述第一数据可以为需要时隙内跳频传输的任意待传输数据。
在具体实施中，所述资源配置信息可以包括：时域资源配置信息及频域资源配置信息。用于传输第一数据的时域资源配置信息及频域资源配置信息，可以采用多种方式接收。所述时域资源配置信息及频域资源配置信息，也可以为多种形式，具体不作限定。
比如，参照图2，在四步随机接入过程中，当所述第一数据为PUSCH时，基站可以通过接入响应消息Msg2发送时域资源配置信息及频域资源配置信息。参照图3，在基于两步随机接入过程中，当所述第一数据为PUSCH时，基站可以通过广播等方式，发送时域资源配置信息及频域资源配置信息。
当所述第一数据为PUSCH时，所述第一数据的时域资源配置信息可以包括传输第一数据的起始正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号标识信息，及时域资源的总长度，具体可以通过起始及长度指示(The Start and Length Indicator，SLIV)值表示。

及
Figure PCTCN2022079917-appb-000025
又如，UE向基站反馈PUCCH前，基站可以预先通过广播的方式，将PUCCH资源映射表发送给UE，再通过指示PUCCH资源映射表的索引值，将所述索引值对应的时频资源，作为传输PUCCH的时频资源。
表2
Figure PCTCN2022079917-appb-000026
在具体实施中，如表2所示，PUCCH资源映射表可以索引值Index信息，与所述索引值Index对应的起始OFDM符号(First symbol)标识信息，与所述索引值对应的用于传输PUCCH的时域资源总长度(Number of symbols)信息。
如表2所示，所述PUCCH资源映射表还可以包括：与所述索引值Index对应的PUCCH格式信息PUCCH format，资源块偏移量
Figure PCTCN2022079917-appb-000027
及与所述索引值对应的初始CS索引值的集合信息。
步骤32，基于所述资源配置信息，确定用于传输所述第一数据的第一资源及第二资源，所述第一资源和所述第二资源在频域上的总带宽小于或等于用户设备所支持的最大带宽。
在具体实施中，对于任意第一数据，只要接收到基站发送的时域资源配置信息及频域资源配置信息，用户设备即可基于所述频域资源配置信息，确定用于传输第一数 据的频域资源，使得所述第一资源和所述第二资源在频域上的总带宽小于或等于用户设备所支持的最大带宽，也就是使得所述第一数据的第一跳与所述第一数据的第二跳之间频率间隔，位于初始上行BWP以内。
本申请的实施例中，所述第一资源，可以理解为第一数据的一跳所占用的时频资源。所述第二资源，可以理解的所述第一数据的另一跳所占用的时频资源。
当所述第一资源为第一数据的第一跳所占用的时频资源，而所述第二资源为第一数据的第二跳所占用的时频资源时，所述第一资源和所述第二资源在频域上的总带宽，指的是自第一资源的频域起始位置至第二资源的频域结束位置之间的频域资源。当所述第一资源为第一数据的第二跳所占用的时频资源，而所述第二资源为第一数据的第一跳所占用的时频资源时，所述第一资源和所述第二资源在频域上的总带宽，指的是自第二资源的频域起始位置至第一资源的频域结束位置之间的频域资源。本申请的实施例中，所述第一资源和所述第二资源在频域上的总带宽，也称为第一资源与第二资源之间的资源跨度，也即第一数据两跳资源之间的资源跨度。
在具体实施中，用户设备可以基于基站的指示，决定如何确定跳频传输第一数据的时域资源及频域资源。当然，用户设备也可以自行决定如何确定跳频传输第一数据的时域资源及频域资源。比如，用户设备可以在检测到资源配置信息中，基站为UE传输第一数据所配置的两跳资源之间的资源跨度超过UE所能支持的最大带宽时，采用本申请实施例中的数据传输方法，确定跳频传输第一数据的时域资源及频域资源。若用户设备检测到资源配置信息中，基站为UE传输第一数据所配置的两跳资源之间的资源跨度，未超过UE所能支持的最大带宽时，则UE可以按照基站的配置传输第一数据，无须对进行两跳资源的额外调整。
所谓传输第一数据的两跳资源之间的资源跨度不超过UE所能支持的最大带宽，比如，初始上行BWP包含270个PRB，起始RB是1，可连续使用的RB数是2，第一跳使用的RB是RB1和RB2。SCS＝15kHz时，当N UL，hop＝00时，根据协议现在的方法，第二跳使用的是第136(1+270/2)和137个RB。而采用本申请的方案，如图5所示，第二跳使用的第54(1+106/2)和55个RB。第1个RB(即RB1)至第55个RB之间的资源跨度小于UE所支持的最大带宽。
在一实施例中，当所述第一数据为PUSCH时，例如，在无线资源控制连接请求Msg3的频域资源配置信息，参照表1，所述频域资源配置信息包括：跳频指示信息N UL,hop。除跳频指示信息N UL,hop外，频域资源配置信息还包括：资源指示值(Resource Indication Value，RIV)。根据RIV和初始UL BWP的带宽，可确定UE传输上行所使用的连续资源块中的起始资源块的序号RBstart的数值和UE可使用的连续资源块的个数。
具体地，确定用于传输第一数据的频域资源时，可以先基于基站配置的RIV，确定UE传输上行所使用的连续资源块中的起始资源块的序号RBstart的数值和UE使用的连续资源块的数量L。RBstart(0)为第一资源的起始频域位置信息，第一资源对应的频域资源为RBstart(0)，RBstart(0)+1，……RBstart(0)+L。
又如，第一消息MsgA的频域配置信息是frequencyStartMsgA-PUSCH、 nrofPRBs-perMsgA-PO和msgA-HoppingBits，通过frequencyStartMsgA-PUSCH可获得RBstart，nrofPRBs-perMsgA-PO为UE可使用的连续PRB的个数，msgA-HoppingBits对应表1里的N UL，hop。
基于所述第一数据的第一资源的起始频域位置信息，及所述跳频指示信息，确定所述第一数据的第二资源的起始频域位置信息，再基于所述第一数据的第一资源的起始频域位置信息、第一数据的第二资源的起始频域位置信息及所述用于传输所述第一数据的频域资源长度信息，确定所述第一数据的第一资源及第二资源对应的频域位置，所述第一资源和所述第二资源在频域上的总带宽小于或等于用户设备所支持的最大带宽。
在具体实施中，所述第一数据的第二资源的起始频域位置，为所述第一数据的第一资源的起始频域位置与预设的相应频域偏移值之和。具体可以采用公式(1)确定第二资源的起始资源块RB start(1)：
RB start(1)＝RB start(0)+RB offset      (1)
其中，RB start(0)为第一资源的起始资源块标识。
在本申请的实施例中，所述频域偏移值与初始上行BWP

中的N表示N个频域资源单元，所述频域资源单元可以为物理资源块(PRB)，当然也可以为物理资源块对等。本申请的实施例中，所述频域资源单元为PRB。
在具体实施中，子载波间隔为15kHz时，

当子载波间隔为30kHz时，

以SCS＝15kHz,
Figure PCTCN2022079917-appb-000034
RBstart(0)＝1，N UL,hop＝00为例，所述第一数据第二跳的起始资源块RBstart(1)为第54RB，RB start(0)与RB start(1)之间的频率间隔小于用户设备所支持的最大带宽
Figure PCTCN2022079917-appb-000035
需要说明的是，在本申请的实施例中，与现有技术不同的是：当N UL,hop的取值为11时，为了简化公式并使得第一数据相邻两跳之间的频率间隔小于

确定第一资源及第二资源的起始资源块后，基于基站预先配置的第一资源及第二资源分别可使用的连续PRB的个数，即可确定第一资源及第二资源占用的具体资源位置。
在本申请的另一实施例中，当所述第一数据为PUCCH时，参照表2，将预设PUCCH资源映射表中所指示的索引值对应的频域资源配置信息，作为频域资源配置信息。此时，所述预设PUCCH资源映射表包括：索引值信息，资源块偏移量
Figure PCTCN2022079917-appb-000038
及与所述索引值对应的初始CS索引值的集合信息。
此时，若
Figure PCTCN2022079917-appb-000039
且UE判定按照基站的配置，第一数据两跳之间的资源跨度超过UE所支持的最大带宽，则确定用于传输第一数据的频域资源时，所述第一数据的第一资源的起始物理资源块为：
Figure PCTCN2022079917-appb-000040
所述第一数据的第二 资源的起始物理资源块为：
Figure PCTCN2022079917-appb-000041
或
Figure PCTCN2022079917-appb-000042
由此使得第一资源及第二资源之间的资源跨度在UE所支持的最大带宽以内。
其中，

比如，当Index＝0，r PUCCH＝7，

时，所述第一数据第一跳起始物理资源块为：
Figure PCTCN2022079917-appb-000046
第二跳起始物理资源块为：
Figure PCTCN2022079917-appb-000047
第一数据两跳之间的资源跨度在UE所支持的最大带宽以内。
在本申请的另一实施例中，当所述第一数据为PUCCH时，参照表2，将预设PUCCH资源映射表中所指示的索引值对应的频域资源，作为频域资源配置信息。此时，所述预设PUCCH资源映射表包括：索引值信息，资源块偏移量
Figure PCTCN2022079917-appb-000048
及与所述索引值对应的初始CS索引值的集合信息。
此时，若
Figure PCTCN2022079917-appb-000049
且UE判定按照基站的配置，第一数据两跳之间的资源跨度超过UE所支持的最大带宽，则所述第一数据的第一资源的起始物理资源块也可以为：
Figure PCTCN2022079917-appb-000050
相应地，所述第一数据的第二资源的起始物理资源块也可以为：
Figure PCTCN2022079917-appb-000051
或
Figure PCTCN2022079917-appb-000052
此时，
Figure PCTCN2022079917-appb-000053
为用户设备所支持的最大带宽。
比如，当Index＝15，r PUCCH＝7，
Figure PCTCN2022079917-appb-000054
时，所述第一数据第一跳起始物理资源块为：
Figure PCTCN2022079917-appb-000055
第二跳起始物理资源块为：
Figure PCTCN2022079917-appb-000056
通过改变第一数据第一跳及第二跳使用的频域资源，使得第一数据的第一跳与所述第一数据的第二跳之间资源跨度，位于UE所支持的最大带宽，而保持基站配置的时域资源不变，由此可以避免用户设备进行射频调频。
步骤33，在所述第一资源和所述第二资源上，传输所述第一数据。
在具体实施中，当所述第一数据为PUSCH时，假设基站配置的用于传输第一数据的时域资源总长度为L个OFDM符号，L≤14，通常情况下，前
Figure PCTCN2022079917-appb-000057
个OFDM符号为第一数据第一跳使用的时域资源，剩下的OFDM符号为第一数据第二跳使用的时域资源。
当所述第一数据为PUCCH时，参照表2，在Index＝1时，第一数据使用的时域资源的起始OFDM符号为第12个OFDM符号，用于传输PUCCH的时域资源长度为2个OFDM符号。具体可以将第12个OFDM符号作为第一数据第一跳使用的时域资源，而将第13个OFDM符号作为第一数据第二跳使用的时域资源。
确定所配置的时域资源及调整后的频域资源后，传输第一数据即可。
由上述内容可知，本申请实施例中数据传输方法，在基于所述频域资源配置信息，确定用于传输第一数据的频域资源时，由于传输第一数据的第一资源与传输第一数据的第二资源在频域上的总带宽小于或等于用户设备所支持的最大带宽，即相邻两跳的频率间隔在用户设备所支持的最大带宽以内，故用户设备无须进行射频调频即可传输数据，完成了时隙内跳频传输数据。

参照图6，本申请实施例还提供了另一种数据传输方法，所述方法可以包括如下步骤：
步骤51，接收用于传输第一数据的资源配置信息；所述资源配置信息配置的时域资源位于一个时隙内。

Figure PCTCN2022079917-appb-000067
及保留值(Reserved)。
在另一实施例中，UE向基站反馈PUCCH前，基站可以预先通过广播的方式，将PUCCH 资源映射表发送给UE，再通过指示PUCCH资源映射表的索引值，将所述索引值对应的时频资源，作为传输PUCCH的时频资源。
相应地，频域资源配置信息包括：资源块偏移量
Figure PCTCN2022079917-appb-000068
及与所述索引值对应的初始CS索引值的集合信息，如表4所示。
表4
Figure PCTCN2022079917-appb-000069
步骤52，基于所述资源配置信息，确定用于传输所述第一数据的第一资源及第二资源，所述第一资源和所述第二资源在时域上的间隔大于或等于用于射频调频的时长。
在具体实施中，UE在获得资源配置信息后，可以先判断按照基站的配置，第一数据两跳之间的资源跨度是否超过UE所支持的最大带宽。当第一数据两跳之间的资源跨度超过UE所支持的最大带宽时，采用实施例2中描述的数据传输方法，确定第一数据的第一资源及第二资源，否则，按照现有3GPP协议要求确定第一资源及第二资源即可。
在具体实施中，为了使得所述第一资源和所述第二资源在时域上的间隔大于或等于用于射频调频的时长，所述资源配置信息配置的时域资源长度，大于或等于用于射频调频的时域资源长度与用于传输PUCCH的时域资源长度之和。其中，所述第一资源，可以为第一数据的第一跳所占用的时频资源，相应地，所述第二资源，可以为所述第一数据的第二跳所占用的时频资源。当然，所述第一资源也可以为第一数据的第二跳所占用的时频资源，所述第二资源也可以为第一数据的第一跳所占用的时频资源。
此时，将时域资源配置信息配置的部分时域资源，用于频域跳频间的射频调频，剩余部分时域资源作为实际传输第一数据的时域资源，由此可以在基站配置的两跳之间时域资源连续的基础上，进行射频调频，完成调频传输。
需要说明的是，在实际应用中，射频调频所需时域资源长度，可以通过协议等方式预先约定。基站也可以通过其它方式获取。基站基于射频调频所需时域资源长度，确定时域资源的起始资源块及实际用于传输PUCCH的时域资源长度。
在具体实施中，当基站配置的用于传输第一数据的时域资源配置信息包括传输第一数据的起始符号标识信息及时域资源的总长度时，结合射频调频所需的时域资源长度，可以确定用于传输第一数据的时域资源长度。
假设基站配置的用于传输第一数据的时域资源总长度为L个OFDM符号，L≤14。进行射频调频所需的时域资源长度为x个OFDM符号，第一数据的第一跳及第二跳共占用的时域资源长度为L-x个，即剩余时域资源长度为L-x个。将剩余时域资源长度为L-x个分为第一剩余时域资源及第二剩余时域资源，所述第一数据的第一跳的时域位置即第一剩余时域资源占用的时域资源，所述第一数据的第二跳的时域位置即第二剩余时域资源占用的时域资源。所述第一数据的第一跳传输结束时刻，即射频调频的起始时刻。射频调频的结束时刻，即第一数据第二跳传输的起始时刻。
在本申请的一实施例中，可以令所述第一数据的第一跳占用的时域资源，与所述第一数据第二跳占用的时域资源相等，即第一剩余时域资源及第二剩余时域资源长度相等。当然，在其它实施例中，第一剩余时域资源及第二剩余时域资源长度也可以不等。
参照图7，L＝6，x＝2时，第一剩余时域资源及第二剩余时域资源长度分别为(L-x)/2＝2，其中，第一数据第一跳使用的时域资源为第1个OFDM符号和第2个OFDM符号，第一数据第二跳使用的时域资源为第5个OFDM符号和第6个OFDM符号，射频调频使用的时域资源为第3个OFDM符号和第4个OFDM符号。
步骤53，在所述第一资源和所述第二资源上，传输所述第一数据。
当所述第一资源和所述第二资源在时域上的间隔大于或等于用于射频调频的时长时，相应地，可以采用以下两种方案确定用于传输第一数据的频域资源。
方案1：所述第一数据的频域资源配置信息可以包括：频域资源总长度、第一跳的起始资源块标识信息及跳频指示信息。具体可以参照表3。
结合表3，可以采用如下公式(2)，确定第二跳的起始资源块RB start(1)：
Figure PCTCN2022079917-appb-000070
其中，RB start(0)为第一跳的起始资源块标识，
Figure PCTCN2022079917-appb-000071
例如，当
Figure PCTCN2022079917-appb-000072
N UL,hop＝00，RB start＝120，则第一跳的起始RB start(0)为第120个RB，第二跳的起始
Figure PCTCN2022079917-appb-000073
即第二跳的起始资源块为第40个RB。
方案2：频域资源配置信息包括：资源块偏移量
Figure PCTCN2022079917-appb-000074
及与所述索引值对应的初始CS索引值的集合信息，如表4所示。
此时，传输第一数据的第一资源及第二资源中，其中第一资源的频域资源的起始

Figure PCTCN2022079917-appb-000084
在具体实施中，基站可以在系统消息(SIB)中引入一条信令，用来指示使用实施例1还是实施例2。当基站指示使用实施例2时，用户设备采用实施例2跳频传输所述第一数据。当基站指示使用实施例1时，用户设备实施例1跳频传输所述第一数据。本申请的实施例中，以时隙内跳频为两跳为例进行描述。可以理解的是，时隙内跳频也可以为三跳以上，无论跳频次数如何，均可以采用本申请实施例中的数据传输方法进行跳频传输。
需要说明的是，本申请实施例中的数据传输方法，不仅适用于随机接入过程中的时隙内跳频传输，还适用于其它场景下的时隙内跳频传输，此处不作限定。
由上述内容可知，本申请实施例中的数据传输方法，当需要在时隙内跳频传输数据时，在时域资源配置信息配置的部分时域资源上进行频域跳频间的射频调频，使用剩余部分时域资源作为用于传输第一数据的时域资源，并使用所述频域资源配置信息配置的频域资源，跳频传输所述第一数据，由此既可以保证相邻两次跳频之间在时间上连续，又可以有一定的时间用于射频调频，从而完成了需要在时隙内跳频的数据传输。
