Description

重复传输方法、装置、通信装置及存储介质 技术领域
本公开涉及通信技术领域，具体而言，涉及重复传输方法、重复传输装置、通信装置和计算机可读存储介质。
背景技术
为了提高通信效率，在相关技术中提出了全双工通信，例如为终端在下行(Downlink，DL)时隙slot中配置上行(Uplink，UL)子带subband，从而终端在下行时隙的上行子带中，可以向网络侧设备发送信息，还可以在下行时隙中上行子带以外的部分接收网络设备发送的信息，从而实现全双工通信。
另外，为了提高传输的可靠性，相关技术中提出了重复传输(repetition)技术，对于同一信息可以重复传输，重复传输中的每次传输可以位于不同的时隙内。由于每次重复传输的频域资源是相同的，这会存在频域资源没有全部位于子带内，或者没有全部位于激活(active)带宽部分(BandWidth Part，BWP)内的问题。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。

图1是根据本公开的实施例示出的一种重复传输方法的示意流程图。本实施例 所示的重复传输方法可以由终端执行，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络设备通信，所述网络设备包括但不限于4G、5G、6G等通信系统中的网络设备，例如基站、核心网等。
如图1所示，所述重复传输方法可以包括以下步骤：
在步骤S101中，确定用于全双工通信的第一时域单元和/或不用于全双工通信的第二时域单元；其中，第一时域单元也可以称作子带全双工(Subband Full Duplex，SBFD)时隙，第二时刻则可以对应称作普通(normal)时隙。
在步骤S102中，确定用于重复传输的第一频域资源；
在步骤S103中，在所述第一时域单元中的重复传输的所述第一频域资源未全部位于所述第一时域单元的子带中时，对所述第一频域资源的处理，以确定全部位于所述第一时域单元的子带中的第二频域资源，在所述第一时域单元中，在所述第二频域资源进行重复传输；和/或
在步骤S104中，在所述第二时域单元中的重复传输的所述第一频域资源未全部位于所述第二时域单元的激活带宽部分中时，对所述第一频域资源的处理，以确定全部位于所述第二时域单元的激活带宽部分中的第三频域资源，在所述第二时域单元中，在所述第三频域资源进行重复传输。
在一个实施例中，时域单元可以是一个或多个系统帧(frame)；时域单元可以是一个或多个子帧(subframe)；时域单元可以是一个或多个时隙(slot)；时域单元可以是一个或多个符号(symbol)，例如正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。
在一个实施例中，由于网络设备为终端配置的重复传输的第一频域资源，在每次重复传输中是相同的，因此终端可以根据重复传输中初始传输的频域资源确定每次重复传输的频域资源。
在一个实施例中，由于每次重复传输可以位于不同时隙中，而时隙又包括用于全双通通信的第一时域单元，以及不用于全双通通信的第二时域单元。
在第二时域单元中，终端可以根据网络设备调度在激活带宽部分(active BWP)中进行重复传输。
在第一时域单元中，频域资源包括激活带宽部分和子带(subband)，终端可 以根据网络设备调度在子带中进行重复传输。其中，子带并不一定位于激活带宽部分之内，例如子带可以完全位于激活带宽部分之内，可以部分位于带宽部分之内，也可以全部位于带宽部分之外。
当重复传输包括在第一时域单元内的重复传输和在第二时域单元内的重复传输时，可能存在一些技术问题。需要说明的是，第一时域单元不是用于表示一个时隙，而是一类时隙，类似地，第二时域单元也不是用于表示一个时隙，而是一类时隙。
每个时隙对应的激活带宽部分可以是相同的，但是由于只有第一时域单元会被配置有子带，所以可以存在的以下情况：
情况1：初始传输位于第二时域单元中，某次重复传输位于第一时域单元中，用于重复传输的第一频域资源全部位于激活带宽部分中，但是没有全部位于子带中；
情况2：初始传输位于第一时域单元中，某次重复传输位于第二时域单元中，用于重复传输的第一频域资源全部位于子带中，但是没有全部位于激活带宽部分中。
对于上述情况1，由于在第一时域单元中，终端根据网络设备调度在子带中进行重复传输，所以在重复传输的第一频域资源全部位于激活带宽部分中，但是没有全部位于子带中的情况下，可以对第一频域资源进行处理，以确定全部位于子带中的第二频域资源。进而在第一时域单元中进行重复传输时，可以使用第二频域资源进行重复传输，从而确保终端能够顺利地完成重复传输。
对于上述情况2，由于在第二时域单元中，终端根据网络设备调度在激活带宽部分中进行重复传输，所以在重复传输的第一频域资源全部位于子带中，但是没有全部位于带宽部分中的情况下，可以对第一频域资源进行处理，以确定全部位于子带中的第三频域资源。进而在第二时域单元中进行重复传输时，可以使用第三频域资源进行重复传输，从而确保终端能够顺利地完成重复传输。
根据本公开的实施例，通过对用于重复传输的第一频域资源进行处理，可以确保在第一时域单元中在全部位于子带内的第二频域资源上进行重复传输，在第二时域单元中在全部位于激活带宽部分内的第三频域资源上进行重复传输，从而确保终端能够顺利地完成重复传输。
在一个实施例中，所述第一时域单元包括以下时隙至少之一：
包含下行子带的上行时隙；
包含下行子带的灵活时隙；
包含上行子带的下行时隙；
包含上行子带的灵活时隙。
例如在包含上行子带的下行时隙中，终端可以在上行子带进行上行通信，在上行子带以外的频域资源中进行下行通信，从而实现全双工通信；例如在包含上行子带的灵活时隙中，终端可以在上行子带进行上行通信，在上行子带以外的频域资源中进行下行通信，从而实现全双工通信；例如在包含下行子带的上行时隙中，终端可以在下行子带进行下行通信，在下行子带以外的频域资源中可以进行上行通信，从而实现全双工通信；例如在包含下行子带的灵活时隙中，终端可以在下行子带进行下行通信，在下行子带以外的频域资源中可以进行上行通信，从而实现全双工通信。
而关于如何确定第一时域单元，可以根据需要进行设置，包括但不限于以下几个实施例所示的方式：
在一个实施例中，网络设备可以先通过第一信息配置第一时域单元的传输方向，例如为第一传输方向，其中，第一信息包括但不限于时分双工上下行配置TDD(Time Division Duplexing)UL-DL configuration、时隙格式指示(Slot Format Indication，SFI)，本实施例中的第一信息是载波级的，也即第一信息适用于同一个载波中的所有BWP。终端基于第一信息可以确定第一时域单元为上行时隙(第一传输方向为上行)或下行时隙(第一传输方向为下行)。
在后续通信过程中，网络设备可以通过第二信息调整终端在第一时域单元的传输方向，例如网络设备通过第二信息可以指示终端在第一时域单元的传输方向为第二传输方向，第二信息可以是动态调度信令，也可以是半静态的配置信息，例如无线资源控制(Radio Resource Control，RRC)信令。
由于第二传输方向与第一传输方向不同，因此，终端在根据第二信息确定在第一时域单元的传输方向为第二传输方向时，可以确定第一时域单元为第一时域单元。例如在第一传输方向为上行传输，第二传输方向为下行传输时，可以确定第一时域单元为包括下行子带的上行时隙；在第一传输方向为下行传输，第二传输方向为上行传输时，可以确定第一时域单元为包括上行子带的下行时隙。
在一个实施例中，网络设备可以先通过小区的TDD UL-DL configuration配置第一时域单元的传输方向，例如为第一传输方向，其中，小区的TDD UL-DL  configuration是小区级(载波级)的，对于同一个载波下的所有BWP是相同的。终端基于第一信息可以确定第一时域单元为上行时隙(第一传输方向为上行)或下行时隙(第一传输方向为下行)。
在后续通信过程中，网络设备可以通过预设BWP pair的TDD UL-DL configuration调整终端在第一时域单元的传输方向，例如网络设备通过预设BWP pair的TDD UL-DL configuration可以指示终端在第一时域单元的传输方向为第二传输方向。其中，预设BWP pair的TDD UL-DL configuration是BWP级的，也即对于不同的BWP可以是不同的。
需要说明的是，在这种情况下，终端可以维护两个激活的BWP pair，一个是预设BWP pair，另一个是预设BWP pair以外的BWP pair，可以称作普通(normal)BWP pair。这两个BWP pair可以对应不同的TDD UL-DL configuration，终端根据预设BWP pair的TDD UL-DL configuration确定在第一时域单元的传输方向。
这两个BWP pair中上行BWP和下行BWP对应的频域资源可以相同，也可以不同。对于在第一时域单元中通信，根据预设BWP pair中上行BWP和/或下行BWP对应的频域资源确定频域资源，而对于在非第一时域单元中通信，根据普通BWP pair中上行BWP和/或下行BWP对应的频域资源确定频域资源。
网络设备还可以通过发送指示信息在至少一个BWP pair中指示预设BWP pair。由于网络设备可以向终端发送BWP级的TDD UL-DL configuration，所以每个BWP pair分别对应TDD UL-DL configuration，因此，网络设备需要通过指示信息告知终端多个BWP pair中的预设BWP pair，以便终端根据预设BWP pair的TDD UL-DL configuration确定第二传输方向。其中，预设BWP pair可以称作参考(reference)BWP pair或者SBFD BWP pair。
由于第二传输方向与第一传输方向不同，因此，终端在根据第二信息确定在第一时域单元的传输方向为第二传输方向时，可以确定第一时域单元为第一时域单元。例如在第一传输方向为上行传输，第二传输方向为下行传输时，可以确定第一时域单元为包括下行子带的上行时隙；在第一传输方向为下行传输，第二传输方向为上行传输时，可以确定第一时域单元为包括上行子带的下行时隙。
在一个实施例中，可以规定TDD频段的半静态(semi-static)时域资源(例如符号、时隙)上或者SFI指示的时域资源上执行全双工操作，那么该时域资源包含的 时隙或所在的时隙，可以作为第一时域单元。
其中，半静态时域资源可以根据通过基站发送的tdd-UL-DL-ConfigurationCommon信令确定，或者可以根据基站发送的tdd-UL-DL-ConfigurationCommon信令以及tdd-UL-DL-ConfigurationDedicated信令确定。
进一步地，网络设备可以指示在第一时域单元上的传输方向(例如上行通信、下行通信等)，例如以下行时域资源为例，可以通过如下两种方式指示终端在所述下行时域资源上的传输方向：
方式一：在下行时域资源内，网络设备为所述终端配置UL subband或者DL subband，在所述UL subband内，终端只能进行上行发送，在所述DL subband内，终端只能进行上行接收。方式二：在下行时域资源内，网络设备为所述终端配置UL subband或者DL subband，并在所述UL subband或者DL subband内进行数据信道的调度或者参考信号的指示，终端根据指示确定进行上行通信或下行通信。
对于第一频域资源的处理，主要包括在频域上进行偏移、交织(interleaving)、跳频(Frequency Hopping，FH)等几种方式，以下通过几个实施例对这几种方式进行示例性说明。
图2是根据本公开的实施例示出的另一种重复传输方法的示意流程图。如图2示，所述第一时域单元包括包含下行子带的上行时隙或灵活时隙，所述对所述第一频域资源的处理，以确定全部位于所述第一时域单元的子带中的第二频域资源包括：
在步骤S201中，在所述重复传输为非交织的下行传输时，在频域上对所述第一频域资源进行偏移，以偏移至所述第一时域单元的下行子带中，其中，偏移后的第一频域资源为所述第二频域资源；和/或
在步骤S202中，在所述重复传输为交织的下行传输时，在所述第一时域单元的下行子带内进行交织操作，以将所述第一频域资源交织至所述第一时域单元的下行子带中，其中，交织后的第一频域资源为所述第二频域资源。
在一个实施例中，对于包含下行子带的上行时隙或灵活时隙，在重复传输为非交织的下行传输时，例如tpye0随机接入(Random Access，RA)物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、type1 RA PDSCH w/o interleaving(非交织)等，若第一频域资源全部位于激活带宽部分中，但是没有全部位于下行子带中， 那么可以对第一频域资源进行偏移。通过在频域上进行偏移，可以将第一时域单元中的第一频域资源全部偏移至下行子带中作为第二频域资源。
需要说明的是，对第一频域资源进行偏移的幅度，可以是网络设备指示的，也可以是基于协议约定确定的。
在一个实施例中，对于下行子带的上行时隙或灵活时隙，在重复传输为交织的下行传输时，例如type1 RA PDSCH w/interleaving(开启了交织)，若第一频域资源全部位于激活带宽部分中，但是没有全部位于下行子带中，那么可以在所述第一时域单元的下行子带内进行交织操作。通过进行交织操作，可以将第一时域单元中的第一频域资源全部交织至下行子带中作为第二频域资源。
图3是根据本公开的实施例示出的又一种重复传输方法的示意流程图。如图3示，所述第一时域单元包括包含上行子带的下行时隙或灵活时隙，所述对所述第一频域资源的处理，以确定全部位于所述第一时域单元的子带中的第二频域资源包括：
在步骤S301中，在所述重复传输为非跳频的上行传输时，在频域上对所述第一频域资源进行偏移，以偏移至所述第一时域单元的上行子带中，其中，偏移后的第一频域资源为所述第二频域资源；和/或
在步骤S302中，在所述重复传输为跳频的上行传输时，在所述第一时域单元的上行子带内进行跳频操作，以将所述第一频域资源跳频至所述第一时域单元的下行子带中，其中，交织后的第一频域资源为所述第二频域资源。
在一个实施例中，对于包含上行子带的下行时隙或灵活时隙，在重复传输为非跳频的上行传输时，例如物理上行共享信道(Physical Uplink Shared Channel，PUSCH)w/o FP(非跳频)等，若第一频域资源全部位于激活带宽部分中，但是没有全部位于上行子带中，那么可以对第一频域资源进行偏移。通过在频域上进行偏移，可以将第一时域单元中的第一频域资源全部偏移至下行子带中作为第二频域资源。
在一个实施例中，对于包含上行子带的下行时隙或灵活时隙，在重复传输为跳频的上行传输时，例如type1 RA PUSCH w/FP(开启了跳频)，若第一频域资源全部位于激活带宽部分中，但是没有全部位于上行子带中，那么可以在所述第一时域单元的下行子带内进行跳频操作。通过进行跳频操作，可以将第一时域单元中的第一频域资源全部跳频至下行子带中作为第二频域资源。
图4是根据本公开的实施例示出的一种频域资源的示意图。
如图4所示，以5个时隙为例，例如时隙结构为DDFUU，其中D表示下行时隙，F表示灵活时隙，U表示上行时隙。时隙结构可以根据针对小区的(Cell Specific)tdd-UL-DL-ConfigurationCommon确定。
第2个时隙为第一时域单元，可以用于全双工通信，其中配置有上行子带，但是上行子带处于激活带宽部分之外。第3个时隙和第4个时隙为第二时域单元，用于进行上行传输，而非用于全双工通信。
例如用于重复传输的第一频域资源全部位于激活带宽部分中，但是并没有全部位于上行子带中，若重复传输为非跳频的上行传输，那么可以在第一时域单元对第一频域资源进行偏移，将第一频域资源偏移至上行子带中得到第二频域资源。其中，第二频域资源与第一频域资源的频域范围可以相同，但是起始位置不同。
进而终端在第3和第4个时隙中，仍然在第一频域资源上进行重复传输，在第2个时隙中则在第二频域资源上进行重复传输。
图5是根据本公开的实施例示出的又一种重复传输方法的示意流程图。如图5示，所述对所述第一频域资源的处理，以确定全部位于所述第二时域单元的激活带宽部分中的第三频域资源包括：
在步骤S501中，在所述重复传输为非交织的下行传输时，在频域上对所述第一频域资源进行偏移，以偏移至所述第二时域单元的下行带宽部分中，其中，偏移后的第一频域资源为所述第三频域资源；和/或
在步骤S502中，在所述重复传输为交织的下行传输时，在所述第二时域单元的下行带宽部分内进行交织操作，以将所述第一频域资源交织至所述第二时域单元的下行带宽部分中，其中，交织后的第一频域资源为所述第三频域资源。
在一个实施例中，对于第二时域单元，在重复传输为非交织的下行传输时，例如tpye0 RA PDSCH、type1 RA PDSCH w/o interleaving等，若第一频域资源全部位于下行子带中，但是没有全部位于激活带宽部分中，那么可以对第一频域资源进行偏移。通过在频域上进行偏移，可以将第一时域单元中的第一频域资源全部偏移至激活带宽部分中作为第三频域资源。
在一个实施例中，对于第二时域单元，在重复传输为交织的下行传输时，例如type1 RA PDSCH w/interleaving，若第一频域资源全部位于下行子带中，但是没有全部位于激活带宽部分中，那么可以在所述第一时域单元的激活带宽部分内进行交织操 作。通过进行交织操作，可以将第一时域单元中的第一频域资源全部交织至激活带宽部分中作为第三频域资源。
图6是根据本公开的实施例示出的又一种重复传输方法的示意流程图。如图6示，所述对所述第一频域资源的处理，以确定全部位于所述第二时域单元的激活带宽部分中的第三频域资源包括：
在步骤S601中，在所述重复传输为非跳频的上行传输时，在频域上对所述第一频域资源进行偏移，以偏移至所述第二时域单元的上行带宽部分中，其中，偏移后的第一频域资源为所述第三频域资源；和/或
在步骤S602中，在所述重复传输为跳频的上行传输时，在所述第二时域单元的上行带宽部分内进行跳频操作，以将所述第一频域资源跳频至所述第二时域单元的下行带宽部分中，其中，交织后的第一频域资源为所述第三频域资源。
在一个实施例中，对于第二时域单元，在重复传输为非跳频的上行传输时，例如PUSCH w/o FP等，若第一频域资源全部位于上行子带中，但是没有全部位于激活带宽部分中，那么可以对第一频域资源进行偏移。通过在频域上进行偏移，可以将第一时域单元中的第一频域资源全部偏移至激活带宽部分中作为第三频域资源。
在一个实施例中，对于第二时域单元，在重复传输为跳频的上行传输时，例如type1 RA PUSCH w/FP，若第一频域资源全部位于上行子带中，但是没有全部位于激活带宽部分中，那么可以在所述第一时域单元的激活带宽部分内进行跳频操作。通过进行跳频操作，可以将第一时域单元中的第一频域资源全部跳频至下行子带中作为第三频域资源。
图7是根据本公开的实施例示出的另一种频域资源的示意图。
如图7所示，以5个时隙为例，例如时隙结构为DDFUU，其中D表示下行时隙，F表示灵活时隙，U表示上行时隙。
第2个时隙为第一时域单元，可以用于全双工通信，其中配置有上行子带，但是上行子带处于激活带宽部分之外。第3个和第4个时隙为第二时域单元，用于进行下行传输，而非用于全双工通信。
例如用于重复传输的第一频域资源全部位于上行子带中，但是并没有全部位于激活带宽部分中，若重复传输为非跳频的上行传输，那么可以在第二时域单元内对第一频域资源进行偏移，将第一频域资源偏移至激活带宽部分中得到第三频域资源。其 中，第三频域资源与第一频域资源的频域范围可以相同，但是起始位置不同。
进而终端在第3和第4个时隙中，在第三频域资源上进行重复传输，在第2个时隙中仍然在第一频域资源上进行重复传输。
图8是根据本公开的实施例示出的又一种频域资源的示意图。
如图8所示，以5个时隙为例，例如时隙结构为DDFUU，其中D表示下行时隙，F表示灵活时隙，U表示上行时隙。
第1个时隙为第一时域单元，可以用于全双工通信，其中配置有上行子带，但是上行子带处于激活带宽部分之外。第2个时隙为第二时域单元，仅用于进行下行传输，而非用于全双工通信。
例如用于重复传输的第一频域资源全部位于上行子带中，且全部位于激活带宽部分中，那么则不必对第一频域资源进行处理，也即终端在第1个时隙和第2个时隙中，都在第一频域资源上进行重复传输。
图9是根据本公开的实施例示出的一种重复传输方法的示意流程图。本实施例所示的重复传输方法可以由网络设备执行，所述网络设备可以与终端通信，所述网络设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图9所示，所述重复传输方法可以包括以下步骤：
在步骤S901中，确定终端用于全双工通信的第一时域单元和/或不用于全双工通信的第二时域单元；
在步骤S902中，确定终端用于重复传输的第一频域资源；
在步骤S903中，在所述第一时域单元中的重复传输的所述第一频域资源未全部位于所述第一时域单元的子带中时，对所述第一频域资源的处理，以确定全部位于所述第一时域单元的子带中的第二频域资源，在所述第一时域单元中，在所述第二频域资源与所述终端进行重复传输；和/或
在步骤S904中，在所述第二时域单元中的重复传输的所述第一频域资源未全部位于所述第二时域单元的激活带宽部分中时，对所述第一频域资源的处理，以确定全部位于所述第二时域单元的激活带宽部分中的第三频域资源，在所述第二时域单元中，在所述第三频域资源与所述终端进行重复传输。
在一个实施例中，由于网络设备为终端配置的重复传输的第一频域资源，在每次重复传输中是相同的，因此终端可以根据重复传输中初始传输的频域资源确定每次重复传输的频域资源。
在一个实施例中，由于每次重复传输可以位于不同时隙中，而时隙又包括用于全双通通信的第一时域单元，以及不用于全双通通信的第二时域单元。
在第二时域单元中，终端可以根据网络设备调度在激活带宽部分(active BWP)中进行重复传输。
在第一时域单元中，频域资源包括激活带宽部分和子带(subband)，终端可以根据网络设备调度在子带中进行重复传输。其中，子带并不一定位于激活带宽部分之内，例如子带可以完全位于激活带宽部分之内，可以部分位于带宽部分之内，也可以全部位于带宽部分之外。
当重复传输包括在第一时域单元内的重复传输和在第二时域单元内的重复传输时，可能存在一些技术问题。需要说明的是，第一时域单元不是用于表示一个时隙，而是一类时隙，类似地，第二时域单元也不是用于表示一个时隙，而是一类时隙。
每个时隙对应的激活带宽部分可以是相同的，但是由于只有第一时域单元会被配置有子带，所以可以存在的以下情况：
情况1：初始传输位于第二时域单元中，某次重复传输位于第一时域单元中，用于重复传输的第一频域资源全部位于激活带宽部分中，但是没有全部位于子带中；
情况2：初始传输位于第一时域单元中，某次重复传输位于第二时域单元中，用于重复传输的第一频域资源全部位于子带中，但是没有全部位于激活带宽部分中。
对于上述情况1，由于在第一时域单元中，终端根据网络设备调度在子带中进行重复传输，所以在重复传输的第一频域资源全部位于激活带宽部分中，但是没有全部位于子带中的情况下，可以对第一频域资源进行处理，以确定全部位于子带中的第二频域资源。进而在第一时域单元中进行重复传输时，可以使用第二频域资源进行重复传输，从而确保终端能够顺利地完成重复传输。
对于上述情况2，由于在第二时域单元中，终端根据网络设备调度在激活带宽部分中进行重复传输，所以在重复传输的第一频域资源全部位于子带中，但是没有全部位于带宽部分中的情况下，可以对第一频域资源进行处理，以确定全部位于子带中的第三频域资源。进而在第二时域单元中进行重复传输时，可以使用第三频域资源进 行重复传输，从而确保终端能够顺利地完成重复传输。
根据本公开的实施例，通过对用于重复传输的第一频域资源进行处理，可以确保在第一时域单元中在全部位于子带内的第二频域资源上进行重复传输，在第二时域单元中在全部位于激活带宽部分内的第三频域资源上进行重复传输，从而确保网络设备能够顺利地完成重复传输。

在一个实施例中，对于下行子带的上行时隙或灵活时隙，在重复传输为交织的下行传输时，例如type1 RA PDSCH w/interleaving(开启了交织)，若第一频域资源全部位于激活带宽部分中，但是没有全部位于下行子带中，那么可以在所述第一时域单元的下行子带内进行交织操作。通过进行交织操作，可以将第一时域单元中的第一频域资源全部交织至下行子带中作为第二频域资源。
