Description

一种上行链路传输方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及一种上行链路传输方法和装置，电子设备和计算机可读存储介质。
背景技术
为了提升上行链路传输的可靠性，可以通过重复传输的方法来实现覆盖增强。例如，对于上行物理共享信道PUSCH，可以使用PUSCH repetition方案来进行PUSCH重复，从而基站等网络设备可以对接收到的多次重复PUSCH信号进行组合，从而获得更高的信噪比。
然而，在PUSCH repetition type A的相关技术中，虽然名义上可以配置最多16次重复，但是对于一些下行时隙配置比较多的TDD(Time-division Duplex,时分双工)系统，例如下行时隙DL:上行时隙UL＝7:3或者4:1等，由于有大量的不可用资源，PUSCH重复会被取消，导致实际的传输次数远比名义上配置的次数少得多。由此，对于一些覆盖较差的情况，会严重降低上行覆盖性能。此外，对于一些覆盖较好的情况，过多的重复发送也造成了资源浪费。
有鉴于此，如何灵活地调节上行链路的重复传输成了亟待解决的问题。
发明内容
有鉴于此，本公开的实施例提出了一种上行链路传输方法和装置，电子设备和计算机可读存储介质，以解决相关技术中的技术问题。

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。
在上行链路中，可以通过重复传输的方法实现覆盖增强。例如在PUSCH repetition type A的技术方案中，可以为终端配置上行链路传输的重复次数，从而终端根据该配置的重复次数进行传输。举例来说，根据PUSCH repetition type A的相关技术，可以为终端配置重复次数N(Number of repetition)，则终端认为在后续N个时隙和N*L(L表示每个时隙中的符号数量)个符号的持续时间内为有效可用资源，由此，终端可以基于该有效可用资源进行PUSCH传输。当然，这里只是以PUSCH为例，在相关技术中，对于PUCCH也可以采用相同的方法进行传输。
在TDD系统中，上述有效可用资源中的N个时隙包括上行时隙和下行时隙，虽然在名义上终端可以在后续N个时隙进行传输，但终端仅能利用其中的上行时隙， 在每个上行时隙中进行一次传输，使得终端实际重复传输的次数比配置的重复次数N少得多。例如对于“DDDSU”结构的帧，下行时隙DL:上行时隙UL＝4:1，即上行时隙的占比为1/5，从而终端实际传输次数为配置的重复次数N的1/5。
因此，基于相关技术中配置的重复次数来指示终端进行上行链路重复传输时，实际的传输次数远比配置的重复次数少。而对于一些覆盖较差的终端，会严重降低上行覆盖性能。
此外，对于一些覆盖较好的终端，按照当前配置的重复次数进行传输，可能也会导致重复过多，造成资源浪费。
有鉴于此，本公开实施例提出一种上行链路传输方法，本实施例方法中，可以灵活地调节上行链路传输的重复次数，在保证覆盖增强的基础上避免资源浪费。
图1是根据本公开的实施例示出的一种上行链路传输方法的示意流程图。本实施例所示的上行链路传输方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站。在一个实施例中，所述基站可以是后续任一实施例所述的上行链路传输方法所适用的基站。
如图1所示，所述上行链路传输方法可以包括以下步骤：
在步骤S101中，接收基站发送的重复次数更新指示。
在一个实施例中，基站可以向终端发送重复次数更新指示。基站可以通过多种方式向终端发送该重复次数更新指示，例如，可以携带在系统消息、DCI(Downlink Control Information，下行控制信息)中等。
在一个实施例中，终端可以接收基站发送的重复次数更新指示，例如可以接收系统消息、或DCI等，并解析得到该重复次数更新指示。
在步骤S102中，基于所述重复次数更新指示和当前配置的上行链路的重复次数，更新上行链路传输的重复次数。
在一个实施例中，基站可以预先为终端配置针对上行链路传输的重复次数，例如8次、16次等，为方便描述，下文将该重复次数记为N。在相关技术中，根据该当前配置的重复次数N，终端可以利用后续N个时隙进行传输，也就是在后续N个时隙中的上行时隙中，在每个上行时隙进行一次上行链路传输。例如，若当前配置的传输 次数为16，若后续16个时隙中包括3个上行时隙，则终端可以在该3个上行时隙中进行3次上行链路传输。
在一个实施例中，终端在接收到基站发送的重复次数更新指示后，可以基于该重复次数更新指示和当前配置的上行链路的重复次数，更新上行链路传输的重复次数。其中，上行链路可以包括PUSCH和PUSCH中的至少一个，也就是说，更新上行链路的重复次数，包括：更新PUSCH和PUSCH的重复次数中的至少一个。从而，终端可以根据更新后的重复次数进行上行链路传输，例如终端可以增加或减少上行链路的传输次数。
需要说明的是，上述实施例中基站发送的重复次数更新指示为半静态调度的指示信息，后续终端可以根据更新后的重复次数周期性地进行上行链路重复传输，而不是仅针对终端当前传输的单次配置。
需要说明的是，在一个实施例中，上述重复次数更新指示的方法，也可以适用于下行链路，例如可以适用于PDCCH和PDSCH的重复次数。
根据图1所示的实施例，基站可以通过重复次数更新指示灵活地指示终端更新对上行链路链路重复传输的次数，例如可以在传输较好的情况下减少传输次数、在传输较差的情况下增加传输次数。从而，终端可以灵活地调整传输上行链路的重复次数，在保证传输可靠性的基础上避免资源浪费。
本公开实施例中，重复次数更新指示可以包括多种不同的形式，下面结合两个具体实施例进行举例说明。
实施例1：重复次数更新指示包括次数系数。
在一个实施例中，次数系数可以是当前配置的重复次数的系数。为方便描述，下文可以将该次数系数记为a。在一个实施例中，基站发送的重复次数更新指示中可以包括次数系数a，终端可以根据次数系数a和当前配置的重复次数N，更新对上行链路传输的重复次数，例如重复次数可以增加、减少或不变。
在一个实施例中，可以将次数系数a与当前配置的重复次数N的乘积a*N，作为更新后的重复次数。例如，当次数系数a小于1时，终端减少重复次数；当次数系数大于1时，终端增加重复次数；当次数系数a等于1时，终端保持重复次数不变。
需要说明的是，这里将次数系数a与重复次数N的乘积作为更新后的重复次数只是示例性说明，在实际应用中，还可以通过其他计算方法来更新重复次数，例如次 数系数的平方与重复次数的乘积等。
需要说明的是，本实施例中基站在重复次数更新指示中携带次数系数a，而不是直接携带新的重复次数N’。一方面，若携带的重复次数N’大于预先定义的最大重复次数，则需要对TDRA(time domain resource allocation，时域资源分配)表格进行修改，而采用次数系数可以避免对TDRA表格进行对应修改，避免影响表格开销；另一方面，若携带的重复次数N’较大，其数值可能会超出指示信息的大小，例如若使用DCI来携带指示信息，DCI中可用的指示位有限，可能无法承载过大的数值，而采用次数系数可以避免指示信息过大的问题。
在一个实施例中，基站确定上述次数系数a的方法也包括多种，下面通过三个实施例进行示例性说明。
实施例1.1：基站根据终端的上行链路传输质量来确定次数系数a。
在一个实施例中，基站可以根据终端的上行链路传输质量来确定次数系数。举例来说，基站可以将终端的SNR(Signal Noise Ratio，信噪比)、MCL(Minimum Coupling Loss，最小耦合损耗)等作为上行链路传输质量。
在一个实施例中，基站可以预先设置预设阈值，然后根据上行链路传输质量与该预设阈值的比较结果来确定次数系数。举例来说，基站可以预先设置第一预设阈值和第二预设阈值，该第一预设阈值可以高于或等于第二预设阈值。
在一个实施例中，响应于所述上行链路传输质量高于第一预设阈值，确定次数系数指示终端减少所述上行链路重复次数；或者，响应于所述上行链路质量低于第二预设阈值，确定次数系数指示终端增加所述上行链路重复次数。
在一个实施例中，基站可以预先设置一个预设候选系数，若基站确定需要对当前配置的上行链路的重复次数进行更新，则基站可以将次数系数确定为该预设候选系数；或者，基站可以预先设置多个预设候选系数，若基站确定需要对当前配置的上行链路的重复次数进行更新，则基站可以根据实际情况进行选择，例如将次数系数确定为该多个预设候选系数中的一个。
以基站指示终端将次数系数a与当前配置的重复次数N的乘积作为更新后的重复次数为例，基站预设候选次数系数可以包括{0,0.5,1,2,4,8}。响应于所述上行链路传输质量高于第一预设阈值，基站可以确定次数系数a小于1，以指示终端减少所述上行链路重复次数；或者，响应于所述上行链路传输质量低于第二预设阈值，基站可以 确定次数系数a大于1，以指示终端增加所述上行链路重复次数；或者，若基站确定不需要更新终端的重复次数，则可以确定次数系数a为1。
在一个实施例中，基站可以设定一个最低传输质量阈值，例如可以设定第二预设阈值为该最低传输质量阈值。基站在确定上行链路传输质量低于第二预设阈值的情况下，可以根据上行链路传输质量与第二预设阈值的距离来确定次数系数，例如可以计算上行链路传输质量与第二预设阈值的差值，然后根据预设的差值与次数系数的对应关系，来确定次数系数。以将信噪比SNR作为传输质量为例，若终端上行链路传输的SNR距离第二预设阈值5dB，则可以配置次数系数为2。当然，这里只是示例性说明，在实际应用中，基站还可以通过其他方法来确定次数系数，本实施例并不进行具体限定。
至此，完成了实施例1.1。根据实施例1.1，基站可以根据终端的上行链路传输质量来确定次数系数，以指示终端更新重复次数。由此，当终端上行链路传输质量较好时，可以减少重复次数，以节约资源；当终端上行链路传输质量较差时，可以增加重复次数，以实现覆盖增强，提高信息传输可靠性。
实施例1.2：基站基于对终端发送的预设数量信息的接收结果，确定次数系数。
在一个实施例中，基站可以确定一个预设数量，例如1,5,10等，然后对终端发送的预设数量的信息的接收结果来确定次数系数。例如，基站可以统计对终端发送的信息的接收结果，然后根据信息的接收结果确定一个综合结果，从而确定次数系数。
在一个实施例中，响应于对终端所发送的预设数量的信息接收成功，确定次数系数指示终端减少所述上行链路重复次数；或者，响应于对终端所发送的预设数量的信息接收失败，确定次数系数指示终端增加所述上行链路重复次数。
在一个实施例中，与上述实施例1.1类似地，基站可以预先设置一个或多个预设候选系数。基站可以将次数系数确定为该预设候选系数，或者基站可以将次数系数确定为该多个预设候选系数中的一个。
在一个实施例中，所述确定次数系数指示终端减少所述上行链路重复次数，包括：对于所述预设数量的信息中的每一条，确定接收成功该条信息所对应的终端重复次数；基于接收成功各条信息分别对应的重复次数，确定次数系数。
举例来说，基站可以设定预设信息数量M，然后统计连续M条信息的接收结果，若接收信息成功，则记录接收成功时终端发送的重复次数；若接收失败，则记录 配置的重复次数。从而，基站可以根据该M条信息的接收结果来确定次数系数。
例如，若M条信息均接收成功，则基站可以将该M条信息接收成功时的终端发送的重复次数来确定次数系数。以M＝5为例，若基站连续接收5条信息成功，则可以根据该5条信息接收成功时终端重复次数来确定次数系数，例如将该5条信息接收成功对应的重复次数的平均值、与当前配置的重复次数的比值，作为次数系数；或者将该5条信息接收成功对应的重复次数的最大值、与当前配置重复次数的比值，作为次数系数等。
例如，若M条信息存在接收失败的情况，则基站可以通过次数系数来指示终端增加重复次数，例如配置次数系数a＝2，或a＝4等。需要说明的是，在更新重复次数后，仍可以继续通过本实施例方法来更新重复次数。
至此，完成了实施例1.2。根据实施例1.2，基站可以基于接收终端发送的信息的接收结果，确定次数系数。当基站在对终端发送的信息接收成功的情况下，可以减少终端传输的重复次数，以节约资源；当基站在对终端发送的信息接收失败的情况下，可以增加终端传输的重复次数，以提高信息传输的可靠性。
实施例1.3：基站基于上行链路TDD时隙配置中上行链路与下行链路的比值，确定次数系数。
在一个实施例中，基站可以根据上行链路TDD时隙配置中UL与DL的比值来确定UL在TDD帧中的占比，然后根据该占比确定次数系数。以次数系数a与重复次数N的乘积作为更新后的重复次数为例，可以将UL占比的倒数作为次数系数。例如，对于“DDDSU”结构的帧，下行时隙DL:上行时隙UL＝4:1，即上行时隙的占比为1/5，则可以确定次数系数为1/5的倒数(即为5)。
由此，基于更新前当前配置的重复次数N，终端可以利用后续N个时隙中的上行时隙来进行上行链路重复传输；基于更新后的重复次数a*N，终端可以利用后续a*N个时隙中的上行时隙来进行上行链路传输，而a为上行时隙的占比的倒数，则该后续a*N个时隙中上行时隙的数量为N，从而终端可以实现N次上行链路传输。
至此，完成了实施例1.3。根据实施例1.3，基站基于上行链路TDD时隙配置中上行链路与下行链路的比值，确定次数系数，并通过该次数系数来使得终端重复传输的次数达到配置的重复次数，从而实现覆盖增强，保证传输可靠性。
实施例2：重复次数更新指示用于指示终端基于当前配置的上行链路的重复次 数确定用于进行上行链路传输的一个或多个上行时隙。
在一个实施例中，终端在接收到重复次数更新指示后，可以基于更新后的重复次数确定一个或多个上行时隙；在所述一个或多个上行时隙重复对上行链路的传输。
以终端中当前配置的重复次数为N为例，在相关技术中，根据该当前配置的重复次数N，终端可以利用后续N个时隙进行传输，也就是在后续N个时隙中的上行时隙中进行传输。根据本实施例，所配置的重复次数可以仍为N，但终端并不是将后续N个时隙作为有效资源，而是根据该重复次数N，确定N个上行时隙，然后将该N个上行时隙作为可用资源，并在该N个上行时隙进行上行链路传输。
在一个实施例中，也可以结合实施例1的方法，先采用次数系数等方法来更新重复次数，然后终端再基于更新后的重复次数来确定上行时隙。例如根据实施例1，确定更新后的重复次数为a*N，由此，终端可以确定a*N个上行时隙，然后在该a*N个上行时隙中进行上行链路传输。
在一个实施例中，基站可以通过DFI(Downlink Feedback Information，下行链路反馈信息)来携带次数系数，所述向终端发送重复次数更新指示，包括：向终端发送携带有次数系数的DFI。基于此，在一个实施例中，终端可以接收基站发送的携带有次数系数的DFI。
至此，完成了实施例2。根据实施例2所述的方法，基站可以通过更新当前配置的上行链路的重复次数的定义来更新终端传输上行链路的重复次数。例如针对当前配置的重复次数N，终端不是在后续N个时隙中的上行时隙中进行传输，而是在后续N个上行时隙中进行传输。由此，基站可以通过本实施例所述方法来指示增加终端传输次数，使得终端重复传输的次数达到配置的重复次数，提高传输可靠性。
在一个实施例中，基站还可以通过DFI来对终端传输中的每一条信息单独进行反馈，从而终端可以根据基站发送的DFI确定重复策略。下面结合图2-图3进行说明。
图2是根据本公开的实施例示出的另一种上行链路传输方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，响应于基站发送的携带有接收失败标识的DFI，按照所述当前配置的重复次数继续重复上行链路传输。
在一个实施例中，基站可以在终端按照当前配置的重复次数N完成N个时隙的重复传输后，向终端发送DFI。例如，若基站对该重复的信息接收失败(例如未接 收到或信息缺失等)，则基站可以在DFI中携带接收失败标识，并将DFI下发给终端。
在一个实施例中，终端在接收到该DFI后，可以按照当前配置的重复次数继续进行传输。或者，终端也可以按照更新后的重复次数继续进行传输。
举例来说，若当前配置的重复次数N为8，而实际上终端在8个时隙中的4个上行时隙重复4次传输后，若接收到基站发送的携带有接收失败的DFI，则终端继续在后续时隙进行重复，例如可以继续进行4次传输。
在一个实施例中，基站也可以通过DFI来指示终端停止传输，下面结合图3进行说明。
图3是根据本公开的实施例示出的一种上行链路传输方法的示意流程图。如图3所示，所述方法还包括：
在步骤S301中，响应于基站发送的不携带接收失败标识的DFI，停止传输；
或者，响应于基站发送的携带接收成功标识的DFI，停止传输。
在一个实施例中，基站可以在终端按照当前配置的重复次数N完成N个时隙的重复传输后，若基站对该重复的信息接收成功，则基站可以在DFI中携带接收成功标识，并将DFI下发给终端。在一个实施例中，终端在确定基站已经成功接收信息的情况下，可以停止传输，然后可以开始传输新的信息。
在一个实施例中，基站下发的DFI中也可以不携带标识，通过缺省的方式指示接收成功，从而指示终端停止传输。需要说明的是，基站和终端预先确定DFI的具体含义，当终端接收到该不携带接收失败标识的DFI时，可以确定基站接收成功，从而终端可以停止传输，然后可以开始传输新的信息。
至此，完成了图2和图3所示的实施例。根据图2和图3所示的实施例，针对每一条传输的信息，基站可以在接收失败的情况下，指示终端继续进行重复，从而保证传输可靠性；基站在接收成功的情况下，及时指示终端停止传输，从而既可以节约能耗、降低信息时延。
图4是根据本公开的实施例示出的一种上行链路传输方法的示意流程图。本实施例所示的上行链路传输方法可以适用于基站，所述基站包括但不限于4G基站、5G基站、6G基站。所述基站可以与作为用户设备的终端进行通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。在一个实施例中， 所述终端可以是上述任一实施例所述上行链路传输方法所适用的终端。
如图4所示，所述上行链路传输方法可以包括以下步骤：
在步骤S401中，向终端发送重复次数更新指示，用于指示终端基于所述重复次数更新指示和当前配置的上行链路的重复次数，更新上行链路传输的重复次数。
在一个实施例中，基站可以向终端发送重复次数更新指示。基站可以通过多种方式向终端发送该重复次数更新指示，例如，可以携带在系统消息、DCI(Downlink Control Information，下行控制信息)中等。
在一个实施例中，终端在接收到基站发送的重复次数更新指示后，可以基于该重复次数更新指示和当前配置的上行链路的重复次数，更新上行链路传输的重复次数。其中，上行链路可以包括PUSCH和PUSCH中的至少一个，也就是说，更新上行链路的重复次数，包括：更新PUSCH和PUSCH的重复次数中的至少一个。
根据图4所示的实施例，基站可以通过重复次数更新指示灵活地指示终端更新对上行链路链路重复传输的次数，例如可以在传输较好的情况下减少传输次数、在传输较差的情况下增加传输次数。从而，终端可以灵活地调整传输上行链路的重复次数，在保证传输可靠性的基础上避免资源浪费。
在一个实施例中，所述重复次数更新指示包括次数系数。在一个实施例中，终端可以将次数系数a与当前配置的重复次数N的乘积a*N，作为更新后的重复次数。或者，终端也可以通过其他计算方法来更新重复次数，例如次数系数的平方与重复次数的乘积等，本实施例不进行限定。
在一个实施例中，基站确定上述次数系数的方法也包括多种，下面结合方法1-方法3进行说明。
方法1：基站可以基于所述终端的上行链路传输质量，确定所述次数系数。
在一个实施例中，所述方法还包括：响应于所述上行链路传输质量高于第一预设阈值，确定次数系数指示终端减少所述上行链路重复次数；或者，响应于所述上行链路质量低于第二预设阈值，确定次数系数指示终端增加所述上行链路重复次数
方法2：基站可以基于对终端发送的预设数量信息的接收结果，确定次数系数。
在一个实施例中，所述方法还包括：响应于对终端所发送的预设数量的信息接收成功，确定次数系数指示终端减少所述上行链路重复次数；或者，响应于对终端所 发送的预设数量的信息接收失败，确定次数系数指示终端增加所述上行链路重复次数。
其中，所述确定次数系数指示终端减少所述上行链路重复次数，包括：对于所述预设数量的信息中的每一条，确定接收成功该条信息所对应的终端重复次数；基于接收成功各条信息分别对应的重复次数，确定次数系数。
在一个实施例中，所述向终端发送重复次数更新指示，包括：向终端发送携带有次数系数的DFI。
在一个实施例中，所述次数系数为预设候选系数，或多个预设候选系数中的一个。
方法3：基站可以基于上行链路TDD时隙配置中上行时隙与下行时隙的比值，确定次数系数。
针对上述方法1-方法3，具体可以参见终端侧实施例1.1-1.3，这里不再赘述。
在一个实施例中，基站下发的重复次数更新指示中也可以不包括次数系数。例如，所述重复次数更新指示用于指示终端基于当前配置的上行链路的重复次数确定一个或多个上行时隙。
基站可以通过更新当前配置的上行链路的重复次数的定义来更新终端传输上行链路的重复次数。例如针对当前配置的重复次数N，终端不是在后续N个时隙中的上行时隙中进行传输，而是在后续N个上行时隙中进行传输。由此，基站可以通过本实施例所述方法来指示增加终端传输次数，使得终端重复传输的次数达到配置的重复次数，提高传输可靠性。
在一个实施例中，基站还可以通过DFI(Downlink Feedback Information，下行链路反馈信息)来对终端传输中的每一条信息单独进行反馈，从而终端可以根据基站发送的DFI确定传输策略。下面结合图5-图6进行说明。
图5是根据本公开的实施例示出的另一种上行链路传输方法的示意流程图。如图5所示，所述方法还包括：
在步骤S501中，响应于接收终端发送的信息失败，向所述终端发送DFI；其中，所述DFI中携带有接收失败标识，用于指示所述终端按照所述当前配置的重复次数继续重复上行链路传输。
图6是根据本公开的实施例示出的另一种上行链路传输方法的示意流程图。如 图8所示，所述方法还包括：
在步骤S601中，响应于接收终端发送的信息成功，向所述终端发送DFI；其中，所述DFI中不携带接收失败标识，用于指示所述终端停止传输。
或者，在步骤S602中，响应于接收终端发送的信息成功，向所述终端发送DFI；其中，所述DFI中携带接收成功标识，用于指示所述终端停止传输。
根据图5和图6所示的实施例，针对每一条传输的信息，基站可以在接收失败的情况下，指示终端继续进行重复，从而保证传输可靠性；基站在接收成功的情况下，及时指示终端停止传输，从而既可以节约能耗、降低信息时延。

在一个实施例中，所述重复次数更新指示用于指示终端更新PUSCH和PUSCH 的重复次数中的至少一个。
下面结合特定的技术细节，概括地示例性说明根据本公开的一个具体寻呼预告指示机制，如下：
在相关技术中，R16中，为了提升URLLC上行数据可靠性，支持PUSCH repetition方案，分为repetition type A和repetition type B两种方案，在R17覆盖增强课题中，为了提高上行链路的覆盖，也可以进行PUSCH重复，在接收到多次重复PUSCH信号可以进行组合，从而获得更高的信噪比。
原有PUSCH repetition type A方案，虽然名义上可以配置最多16次重复，但是对于一些下行时隙配置比较多的TDD系统，如(DL:UL＝7:3或者4：1)，由于有大量的不可用资源，PUSCH repetition会被取消，导致实际的repetition次数远比名义上配置的次数少得多，从而严重降低上行覆盖性能。而对于一些覆盖较好的情况，过大的重复次数也是一种资源浪费。
本公开实施例提出一种PUSCH repetition type A的重复方案，原有标准规定，一旦配置了N标称重复，则认为在后续N个时隙和N*L个符号的持续时间内为有效可用资源，UE分别在有效上行资源上发送PUSCH。当覆盖情况较好，可以根据SNR的接受质量提前结束PUSCH type A的传输，避免资源的浪费。当覆盖特别差时，如果可用资源用完，但接受质量不满足时，需要保证PUSCH actual repetition的次数，让其继续传输，保证接受质量。
本公开实施例中，可以缩小/扩展最大名义重复次数N
需要说明的是，如果直接从16修改到32,一是对应的TDRA表格也需要跟着修改，影响TDRA表格开销，影响DCI指示比特数，此外32这个值也可能过大或者过小，并无法适用于所有场合。
在一个实施例中可以定义一个只针对重复次数的扩展或者缩小系数β对N进行扩展或者缩小，例如N’＝N*β。
在一个实施例中，β值的确定方法，可以包括
1、定义候选值β＝{0.5,1,2,4,8}，提前根据CE target目标进行确定β，如对于需要提升5dB,RRC提前配置β＝2。
2、定义候选值β＝{0.5,1,2,4,8}，引入DFI，根据ACK/NACK确定，DCI指示
3、不定义具体值，提前根据TDD系统DL:UL时隙配置计算得到。
在一个实施例中，可以修改N的定义和对应的资源范围。原协议中定义N代表着着后续连续N个slot，现在将N的定义修改为N个后续上行slot，对应的计数规则也应跟着修改。
在一个实施例中，可以根据缺省的重传次数进行续传。
举例来说，如果配置了8次，实际传输4次。基站解调并下发DFI，如果DFI指示NACK，终端顺延传输4次。否则，终止传输，开始发送新的数据TBS。
