Description

用于PUCCH的通信方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种用于PUCCH的通信方法、装置及存储介质。
背景技术
随着通信技术的发展，为了保证覆盖范围，需要使用基于波束(beam)的发送和接收。当网络设备(例如基站)有多个发送接收点(Transmission Reception Point，TRP)时，可以使用多个TRP(Multi-TRP)/多面板(PANEL)为终端提供服务。网络设备多TRP/PANEL的应用主要为了改善小区边缘的覆盖，在服务区内提供更为均衡的服务质量，用不同的方式在多个TRP/PANEL间协作传输数据。从网络形态角度考虑，以大量的分布式接入点加基带集中处理的方式进行网络部署将更加有利于提供均衡的用户体验速率，并且显著的降低越区切换带来的时延和信令开销。利用多个TRP/PANEL之间的协作，从多个角度的多个波束进行信道的传输/接收，可以更好的克服各种遮挡/阻挡效应，保障链路连接的鲁棒性，适合超可靠低延时通信(Ultra Reliable Low Latency Communication，URLLC)业务提升传输质量和满足可靠性要求。
在R16研究阶段，基于下行多TRP/PANEL间的多点协作传输技术的应用，对物理下行共享信道(physical downlink shared channel，PDSCH)进行了传输增强。由于数据传输包括上下行信道的调度反馈。因此在URLLC的研究中，只对下行数据信道增强不能保证业务性能。因此在R17的研究中，继续对下行控制信道(physical downlink control channel，PDCCH)以及上行控制信道(physical uplink control channel，PUCCH)和上行共享信道(physical uplink shared channel，PUSCH)进行增强。
基于multi-TRP的上行增强方案，主要基于PUCCH/PUSCH重复传输方案。在R15/16考虑上行覆盖问题，对长PUCCH(对应PUCCH格式1/3/4)引入了在多个时隙(slot)中进行repetition重复传输的机制，不同的PUCCH资源在每个slot的不同传输时机中按照相同的传输符号长度进行传输。R17基于multi-TRP的上行增强方案，主要基于R16的PUSCH重复传输方案。在R17multi-TRP增强中，PUCCH支持在不同的传输时机(Transmission Occasion，TO)上向不同的TRP方向上协作发送同一传输块(Transport Block，TB)，以进一步应用空间复用传输提高传输可靠性。
对于PUCCH信道传输，可以有时隙间(inter-slot)的重复方式(即Scheme1)以及时隙内(intra-slot)的重复方式。时隙内的传输方式包括时隙内基于跳频的重复传输方案(即Scheme 2)以及时隙内基于子时隙(sub-slot)的重复传输方案(即Scheme3)。然而，在 R17基于multi-TRP的PUCCH增强中，对于不同TRP发送的重复增强方案包括的时隙内(包括scheme 2&scheme 3)和时隙间(scheme 1)的传输方案并不能满足multi-TRP传输下的各种场景需求，故需要提供可能增强方案用来增强传输可靠性。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的用于PUCCH的通信方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相 连接，并进行数据传输。其中，网络设备与终端之间基于波束进行数据传输。其中，网络设备与终端之间可以基于Multi-TRP进行PUSCH上行传输的增强。参阅图1所示，在下行通信过程中，多个TRP面向终端发送。在上行通信过程中，终端面向不同TRP发送。
可以理解的是，网络设备基于Multi-TRP与终端进行数据传输的TRP数量可以为一个或多个。图1所示的无线通信系统中网络设备基于TRP(1)、TRP(2)、TRP(3)和TRP(4)与终端进行数据传输仅是进行示意性说明，并不引以为限。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、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，终端可以是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：智能手机(Mobile Phone)、客户前置设备(Customer  Premise Equipment，CPE)，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开实施例中网络设备与终端之间基于波束进行数据传输。其中，网络设备和终端可以基于多TRP/PANEL间的多点协作传输技术对PUCCH进行增强。对PUCCH的增强可以是在多个slot中进行重复传输的机制。图2示出了一种PUCCH重复传输示意图。参阅图2所示，不同的PUCCH资源在每个slot的不同传输时机中按照相同的传输符号长度进行传输。一个PUCCH重复传输只能使用一个PUCCH资源，该PUCCH资源配置一个beam方向即空间信息(spatialRelationInfo)，并且应用于所有的传输时机上。网络通过无线资源控制(Radio Resource Control，RRC)高层信令为PUCCH格式(PUCCH format)配置支持的相应的重复传输次数，指示的范围定义为{1,2,4,8}，不同的PUCCH资源可能对应不同的PUCCH格式。
在R17基于multi-TRP的PUCCH增强中，PUCCH支持在不同的TO上向不同的TRP方向上协作发送同一传输块TB,以进一步应用空间复用传输提高传输可靠性。对于PUCCH信道传输，R17增强的可能方案为：
方案1：时隙间(inter-slot)的重复方式(即Scheme1)
同R15/16的TDM重复传输方式，实现在面向多个TRP的多个beam方向上在多个时隙上分时协作发送，重复传输时隙数目即配置的传输占用的时隙数目，每个时隙的资源分配都相同，即使用每个时隙上相同的时频资源上发送PUCCH的重复版本。
方案二：时隙内(intra-slot)的重复方式，现有协议不支持，即面向多个TRP的多个beam方向上在一个时隙内分时联合传输。但对于时隙内的重复方式可以存在如下两种重复传输方案：
A：基于时隙内跳频发送为基础的传输方案(即Scheme 2)，即在一个PUCCH资源内，时隙内前后两跳(hop)对应的不同符号组上分别按照不同的beam方向发送；跳频功能(时隙内跳频FH)可以开启，也可以关闭。图3示出了一种时隙内基于跳频的重复传输方案传输示意图。参阅图3所示，包括PUCCH资源占用N个符号，在时隙内第一跳频资源块占用floor(N/2)个时域符号，映射在面向TRP1对应的波束方向上发送，第二跳频资源块占用N-floor(N/2)个时域符号，映射在面向TRP2对应的波束方向上发送。其中，波束1和波束2映射在同一时隙的不同跳频资源上，在时隙内跳频开启时，同一时隙内的不同跳频资源起始的频率位置相差网络配置的频率偏差，在时隙内跳频关闭时，同一时隙内的不同跳 频资源起始频率相同。
其中，本公开实施例中时隙内基于跳频的重复传输方案也可以理解为是时隙内基于跳波束的重复传输方案，故本公开实施例中时隙内基于跳频的重复传输方案和时隙内基于跳波束的重复传输方案有时会交替使用，但本领域技术人员应理解其含义的一致性。
B：基于时隙内子时隙(sub-slot)的传输方案(即Scheme3)：即在时隙内以sub-slot为单位进行PUCCH的重复发送，定义为时隙多次发送(即重复传输次数K>＝2)，每次重复发送的TO中分别按照不同的beam方向发送。图4示出了一种时隙内基于sub-slot的重复传输方案传输示意图。参阅图4所示，包括PUCCH资源占用N个符号，在时隙内第一子时隙资源块占用floor(N/2)个时域符号，映射在面向TRP1对应的波束方向上发送，第二子时隙资源块占用N-floor(N/2)个时域符号，映射在面向TRP2对应的波束方向上发送。其中，波束1和波束2映射在同一时隙的不同子时隙资源上。
其中，终端面向不同TRP发送的PUCCH的波束发送方向和不同的传输时机之间的映射关系有多种映射方案可以如下三种方案，高层信令会配置本次PUCCH发送使用的波束映射方案：
方案a：周期映射。两个波束方向依次循环映射到配置的多个传输时机上，例如4次传输时，波束方向映射的图样是#1#2#1#2。
方案b：连续映射。两个波束方向连续循环映射到配置的多个传输时机上，例如4次传输时，波束方向映射的图样是#1#1#2#2，对于4次以上的传输，则重复该图样，如对于8次传输，则TCI state映射的图样是#1#1#2#2#1#1#2#2。
方案c：对半映射。两个波束方向连续映射到配置的多个传输时机上，例如8次传输时，波束方向映射的图样是#1#1#1#1#2#2#2#2。
基于以上描述可知，在R17基于multi-TRP的PUCCH增强中，对于不同TRP发送的增强方案主要包括时隙内(包括scheme 2&scheme 3)和时隙间(scheme 1)的传输方案。并且，上述涉及的不同重复传输方案大部分参数都是RRC配置的半静态参数。然而，不同的重复传输方案可以针对不同的场景和业务要求。那么当具体场景和业务变化时，由于大部分参数都是RRC配置的半静态参数，不能及时动态改变配置，就需要网络重配置来解决，这样会降低系统的调度灵活性和效率。
有鉴于此，本公开实施例提供一种用于PUCCH的通信方法，在该用于PUCCH的通信方法中，终端面向多个TRP方向协作发送PUCCH时，支持不同重复传输方案之间的动态切换，以提高系统调度灵活性以及效率。
图5是根据一示例性实施例示出的一种用于PUCCH的通信方法的流程图，该用于 PUCCH的通信方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图5所示，用于PUCCH的通信方法用于网络设备中，包括以下步骤。
在步骤S11中，响应于确定终端面向多个TRP方向协作发送PUCCH，发送指示信息。
其中，本公开实施例中，网络设备发送的指示信息用于指示终端动态切换重复传输方案，以面向多个TRP方向协作重复发送PUCCH。
进一步的，重复传输方案包括时隙间重复传输方案、时隙内基于跳波束的重复传输方案以及时隙内基于子时隙的重复传输方案。
本公开实施例中，网络设备确定终端面向多个TRP方向协作发送PUCCH的情况下，通过指示信息指示不同的PUCCH传输方案之间的配置及动态切换方式，可以使终端面向不同的TRP方向按照不同的传输方案协作发送PUCCH。例如，当媒体接入控制(Media Access Control，MAC)-控制单元(Control Element，CE)激活对应的PUCCH资源的波束方向信息(spatial relation info)个数为2时，对应multi-TRP传输，面向不同的TRP方向按照不同的传输方案协作发送PUCCH。
本公开实施例提供的一种实施方式中，网络设备可以通过配置子时隙传输配置参数，实现不同重复传输方案的切换。即，网络设备可以通过发送子时隙传输配置参数，指示面向多个TRP方向协作重复发送PUCCH所占用的子时隙资源信息。
图6是根据一示例性实施例示出的一种用于PUCCH的通信方法的流程图，该用于PUCCH的通信方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图6所示，用于PUCCH的通信方法用于网络设备中，包括以下步骤。
在步骤S21中，响应于确定终端面向多个TRP方向协作发送PUCCH，发送子时隙传输配置参数。
本公开实施例中，子时隙传输配置参数用于指示面向多个TRP方向协作重复发送PUCCH所占用的子时隙资源信息。
本公开实施例中可以通过配置子时隙传输配置参数，实现不同重复传输方案之间的动态切换。例如，网络设备通过配置子时隙传输配置参数实现scheme1和scheme3之间的动态切换。并且可以通过动态改变scheme3的subslot配置，实现scheme2和scheme3之间的动态切换。
本公开实施例中可以通过RRC信令半静态配置子时隙传输配置参数。
图7是根据一示例性实施例示出的一种用于PUCCH的通信方法的流程图，该用于PUCCH的通信方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图7所示，用于PUCCH的通信方法用于网络设备中，包括以下步骤。
在步骤S31中，响应于确定终端面向多个TRP方向协作发送PUCCH，配置RRC信令。其中，RRC信令中包括PUCCH配置信息，PUCCH配置信息配置在PUCCH资源级别或PUCCH资源集合级别或PUCCH格式级别的子时隙配置长度信息。
例如，在RRC参数PUCCH_config中添加PUCCH资源(即resource)级别或者PUCCH格式(即PUCCH format)级别的subslotLengthForPUCCH参数，进行subslot传输配置。例如该subslotLengthForPUCCH参数可以配置子时隙例如为2，7符号长度或其他取值。
可以理解的是，相关协议中subslotLengthForPUCCH参数不用于指示PUCCH重复传输的子时隙资源大小。本公开实施例中通过subslotLengthForPUCCH参数指示PUCCH重复传输的子时隙资源大小，实现不同重复传输方案之间的动态切换。
本公开实施例中可以通过MAC-CE配置或修改该PUCCH资源对应的subslot传输配置，实现不同重复传输方案之间的动态切换。
其中，本公开实施例中可以激活(enable)或者去激活(disable)该子时隙传输配置参数，使该资源在时隙重传和子时隙重传方案的配置之间直接动态切换，适用于后续的调度需求。
一种实施方式中，本公开实施例中可以激活子时隙传输配置参数，以实现由时隙间重复传输方案切换至时隙内基于子时隙的重复传输方案，或者由时隙内基于跳波束的重复传输方案切换至时隙内基于子时隙的重复传输方案。
例如，当前PUCCH配置方案为每时隙占用2个符号重传4次的scheme1时，通过MAC-CE激活子时隙传输配置参数，其他传输参数可以不变的情况下将资源配置方式从时隙间的重传动态切换到scheme3的子时隙重传方案即每个子时隙占用2个符号在时隙内重传4次。
再例如，当前PUCCH配置方案为时隙内占用7个符号的scheme2方案，通过MAC-CE激活子时隙传输配置参数后，可以将资源配置方式切换到子时隙重传方案即每个子时隙占用7个符号，同时需要修改传输次数参数，可以实现到scheme3方案的动态切换。
另一种实施方式中，本公开实施例中可以去激活子时隙传输配置参数，以实现由时隙内基于子时隙的重复传输方案切换至时隙间重复传输方案，或者由时隙内基于子时隙的重复传输方案切换至时隙内基于跳波束的重复传输方案。
例如，当前PUCCH配置方案为每时隙占用2个符号重传4次的scheme1时，若去激活子时隙传输配置参数，则将资源配置方式从scheme3的子时隙重传方案(每个子时隙占用2个符号在时隙内重传4次)，动态切换到scheme1的时隙间重传方案。
再例如，当前PUCCH配置方案为时隙内占用7个符号的scheme2方案，若去激活子 时隙传输配置参数后，可以将资源配置方式由子时隙重传方案(每个子时隙占用7个符号)动态切换到时隙间重复传输方案。并且可以通过修改传输次数参数，可以实现scheme3方案与scheme2方案的动态切换。
本公开实施例中也可以通过重配置子时隙传输配置参数为无效传输配置参数，实现重复传输方案的动态切换。例如，通过重配置子时隙传输配置参数为无效传输配置参数，以实现时隙间重复传输方案与时隙内基于子时隙的重复传输方案的动态切换。
本公开实施例中将重配置子时隙传输配置参数为无效传输配置参数，也可以理解为是在当前使用的重复传输方案上不使用该子时隙传输配置参数。
一示例中，通过重配置子时隙传输配置参数为无效传输配置参数以指示使用scheme1的重复阐述方案。或者，也可以直接改变子时隙的大小配置，使其适用于当前的调度需求。例如，subslotLengthForPUCCH参数可以配置数值“0”用来指示时隙级别的传输。并且，通过在scheme3配置下，通过重新配置该参数，实现scheme1和scheme3的动态切换。
一种实施方式中，本公开实施例中也可以通过修改子时隙传输配置参数为子时隙占用资源大小，以实现由时隙间重复传输方案切换至时隙内基于子时隙的重复传输方案。
例如，通过修改子时隙传输配置参数的具体数值来实现scheme3下的具体子时隙占用资源大小。例如，当前配置子时隙为7个符号的传输可以改变为子时隙为2个符号的传输配置，并直接用于本次调度传输。
本公开实施例提供的用于PUCCH的通信方法中，也可以通过时隙数量配置参数(nrofslots参数)，实现不同重复传输方案之间的动态切换。
图8是根据一示例性实施例示出的一种用于PUCCH的通信方法的流程图，该用于PUCCH的通信方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图8所示，用于PUCCH的通信方法用于网络设备中，包括以下步骤。
在步骤S41中，发送时隙数量配置参数，时隙数量配置参数用于指示面向多个TRP方向协作发送PUCCH进行重复传输所占用的时隙数量。
本公开实施例中，网络设备配置并发送时隙数量配置参数，以指示面向多个TRP方向协作发送PUCCH进行重复传输所占用的时隙数量，进而可以实现scheme1和scheme2之间的动态切换，以及scheme2和scheme3之间的动态切换。
一种实施方式中，本公开实施例中可以通过MAC-CE修改该PUCCH资源对应的传输次数参数(时隙数量配置参数)，实现不同重复传输方案之间的动态切换。
本公开实施例一种实施方式中，可以激活或者去激活该时隙数量配置参数，实现资源在时隙重传和波束跳波束重传方案的配置之间直接动态切换，适用于后续的调度需求。
例如，本公开实施例中可以激活时隙数量配置参数，以实现由时隙内基于跳波束的重复传输方案切换至时隙间重复传输方案，或者由时隙内基于跳波束的重复传输方案切换至时隙内基于子时隙的重复传输方案。
一示例中，当配置了4个符号4次时隙间重传的scheme1方案的PUCCH资源，通过MAC-CE激活重传次数参数K，则可以由4个符号的波束跳波束重传方案(即scheme2方案)切换至时隙间重复传输方案(即scheme1方案)。同理适用于scheme2和scheme3之间的切换情况。
再例如，本公开实施例中可以去激活时隙数量配置参数，以实现由时隙间重复传输方案切换至时隙内基于跳波束的重复传输方案，或者由时隙内基于子时隙的重复传输方案切换至时隙内基于跳波束的重复传输方案。
一示例中，当配置了4个符号4次时隙间重传的scheme1方案的PUCCH资源，通过MAC-CE去激活重传次数参数K，则默认切换到4个符号的波束跳波束重传方案(即scheme2方案)上。同理适用于scheme2和scheme3之间的切换情况。
本公开实施例另一种实施方式中，可以重配置时隙数量配置参数，以实现由时隙间重复传输方案切换至时隙内基于跳波束的重复传输方案，或者由时隙内基于子时隙的重复传输方案切换至时隙内基于跳波束的重复传输方案。
一示例中，对于scheme2参数配置修改为1。当配置了4个符号4次时隙间重传的scheme1方案的PUCCH资源，通过MAC-CE修改时隙数量配置参数(重传次数参数K＝1)，则默认切换到4个符号的波束跳频重传方案即scheme2方案上。同理适用于scheme2和scheme3之间的切换情况。
本公开实施例提供的用于PUCCH的通信方法中，也可以通过PUCCH资源配置信息，实现不同重复传输方案之间的动态切换。例如，在同一个PUCCH resource set中分别配置对应scheme1，scheme2，sheme3传输的不同PUCCH资源配置。通过DCI指示PRI来激活当前采用的调度传输方案。其中，PRI可以理解为是PUCCH资源指示(PUCCH Resource Indicator)，用来指示本次调度具体使用当前PUCCH组中的哪个PUCCH资源传输。进一步可以理解的是，网络设备可以通过RRC信令配置当前PUCCH的传输方案。
图9是根据一示例性实施例示出的一种用于PUCCH的通信方法的流程图，该用于PUCCH的通信方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图9所示，用于PUCCH的通信方法用于网络设备中，包括以下步骤。
在步骤S51中，发送PUCCH资源配置信息，PUCCH资源配置信息包括第一PUCCH资源配置信息，或者第二PUCCH资源配置信息，或者第三PUCCH资源配置信息。
其中，第一PUCCH资源配置信息对应时隙间重复传输方案，第二PUCCH资源配置信息对应时隙内基于跳波束的重复传输方案，第三PUCCH资源配置信息对应时隙内基于子时隙的重复传输方案。
本公开实施例中，网络设备发送PUCCH资源配置信息，以指示终端使用PUCCH资源配置信息对应的重复传输方案，进行面向多个TRP方向协作发送PUCCH。
一示例中，当前PUCCH的传输方案为使用第一PUCCH资源配置信息对应时隙间重复传输方案。若网络设备发送第三PUCCH资源配置信息，则可以动态切换至第三PUCCH资源配置信息对应时隙内基于子时隙的重复传输方案。
本公开实施例提供的用于PUCCH的通信方法，通过不同的方法实现multi-TRP传输下的不同PUCCH信道传输方案之间的切换，可以提高调度的灵活性，更加快速灵活的适应信道和业务变化，减少时延，更为有效的利用系统资源，提高系统性能。
基于相同的构思，本公开实施例提供一种用于终端的PUCCH通信方法。
图10是根据一示例性实施例示出的一种用于PUCCH的通信方法的流程图，该用于PUCCH的通信方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图10所示，用于PUCCH的通信方法用于终端中，包括以下步骤。
在步骤S61中，接收指示信息，指示信息用于指示终端动态切换重复传输方案，以面向多个TRP方向协作重复发送PUCCH。
其中，重复传输方案包括时隙间重复传输方案、时隙内基于跳波束的重复传输方案以及时隙内基于子时隙的重复传输方案。
在步骤S62中，基于指示信息，面向多个TRP方向协作发送PUCCH。
本公开实施例中，终端面向多个TRP方向协作发送PUCCH的情况下，通过指示信息可以在面向不同的TRP方向进行数据传输时，动态切换不同的PUCCH传输方案，可以使终端面向不同的TRP方向按照不同的传输方案协作发送PUCCH。
本公开实施例提供的一种实施方式中，网络设备可以通过配置子时隙传输配置参数，实现不同重复传输方案的切换。即，网络设备可以通过发送子时隙传输配置参数，指示面向多个TRP方向协作重复发送PUCCH所占用的子时隙资源信息。

在步骤S81中，接收RRC信令，RRC信令中包括PUCCH配置信息，PUCCH配置信息配置为PUCCH资源级别或PUCCH资源集合级别或PUCCH格式级别的子时隙配置长度信息。
其中，RRC信令半静态配置子时隙传输配置参数。
例如，在RRC参数PUCCH_config中添加PUCCH资源(即resource)级别或者PUCCH格式(即PUCCH format)级别的subslotLengthForPUCCH参数，进行subslot传输配置。例如该subslotLengthForPUCCH参数可以配置子时隙例如为2，7符号长度或其他取值。
可以理解的是，相关协议中subslotLengthForPUCCH参数不用于指示PUCCH重复传输的子时隙资源大小。本公开实施例中通过subslotLengthForPUCCH参数指示PUCCH重复传输的子时隙资源大小，实现不同重复传输方案之间的动态切换。
本公开实施例中可以通过MAC-CE配置或修改该PUCCH资源对应的subslot传输配置，实现不同重复传输方案之间的动态切换。
其中，本公开实施例中可以激活或者去激活该子时隙传输配置参数，使该资源在时隙重传和子时隙重传方案的配置之间直接动态切换，适用于后续的调度需求。
