Description

无线通信方法和第一设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及无线通信方法和第一设备。
背景技术
目前，新空口-非授权(New Radio Unlicensed,NR-U)系统(非授权频谱上的NR系统)中，通信设备根据过去某一个时间单元或参考时间段内传输的PDSCH对应的HARQ反馈值调整各个优先级对应的竞争窗口。但是，NR-U系统中只支持单播，也就是说，上述参考时间单元内或参考时间段内的每一个PDSCH只对应着来自一个接收设备的HARQ反馈值。
然而，在组播、多播以及广播的场景下，一个PDSCH将对应着来自多个接收设备的HARQ反馈值，同时也存在接收设备不对PDSCH进行反馈的情况。因此，在NR-U系统中针对单播场景的通信设备调整竞争窗口的方法不适合应用于组播、多播和广播的场景。同时，当SL系统部署在非授权频谱上，即SL-U系统中，进行组播、多播和广播的终端如何调整竞争窗口也需要相应的解决方案。
发明内容
本申请实施例提供一种无线通信方法和第一设备，针对组播、多播以及广播场景，不仅能够用于调整竞争窗口，还能够避免多个第一设备进行LBT时使用相同的竞争窗口，进而有利于降低多个第一设备之间的干扰。

在一种实现方式中，该处理器为一个或多个，该存储器为一个或多个。
在一种实现方式中，该存储器可以与该处理器集成在一起，或者该存储器与处理器分离设置。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
图1是本申请实施例的一个应用场景的示意图。
如图1所示，通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解，本申请实施例仅以通信系统100进行示例性说明，但本申请实施例不限定于此。也就是说，本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、5G通信系统(也称为新无线(New Radio，NR)通信系统)，或未来的通信系统等。
在图1所示的通信系统100中，网络设备120可以是与终端设备110通信的接入网设备。接入网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内的终端设备110(例如UE)进行通信。
网络设备120可以是长期演进(Long Term Evolution，LTE)系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是下一代无线接入网(Next Generation Radio Access Network，NG RAN)设备，或者是NR系统中的基站(gNB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备120可以为中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器，或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
终端设备110可以是任意终端设备，其包括但不限于与网络设备120或其它终端设备采用有线或者无线连接的终端设备。
例如，所述终端设备110可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进网络中的终端设备等。
终端设备110可以用于设备到设备(Device to Device，D2D)的通信。
无线通信系统100还可以包括与基站进行通信的核心网设备130，该核心网设备130可以是5G核心网(5G Core，5GC)设备，例如，接入与移动性管理功能(Access and Mobility Management Function，AMF)，又例如，认证服务器功能(Authentication Server Function，AUSF)，又例如，用户面功能(User Plane Function，UPF)，又例如，会话管理功能(Session Management Function，SMF)。可选地，核心网络设备130也可以是LTE网络的分组核心演进(Evolved Packet Core，EPC)设备，例如，会话管理功能+核心网络的数据网关(Session Management Function+Core Packet Gateway，SMF+PGW-C)设备。应理解，SMF+PGW-C可以同时实现SMF和PGW-C所能实现的功能。在网络演进过程中，上述核心网设备也有可能叫其它名字，或者通过对核心网的功能进行划分形成新的网络实体，对此本申请实施例不做限制。
通信系统100中的各个功能单元之间还可以通过下一代网络(next generation，NG)接口建立连接实现通信。
例如，终端设备通过NR接口与接入网设备建立空口连接，用于传输用户面数据和控制面信令； 终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接；接入网设备例如下一代无线接入基站(gNB)，可以通过NG接口3(简称N3)与UPF建立用户面数据连接；接入网设备可以通过NG接口2(简称N2)与AMF建立控制面信令连接；UPF可以通过NG接口4(简称N4)与SMF建立控制面信令连接；UPF可以通过NG接口6(简称N6)与数据网络交互用户面数据；AMF可以通过NG接口11(简称N11)与SMF建立控制面信令连接；SMF可以通过NG接口7(简称N7)与PCF建立控制面信令连接。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
需要说明的是，本申请的方案可适用于非授权频谱。
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。例如，WIFI系统就部署在非授权频谱上。
首先，法规对于通信设备在非授权频谱上进行传输的带宽有所限制。即通信设备发送所占带宽的跨度至少为总频谱带宽的L％,通常的法规要求中L＝80。例如，假设总带宽是100个PRB，那么通信设备发送时，所用最低的PRB索引与最高的PRB索引至少要相差80。如果通信设备需要2个PRB发送数据，占用了PRB 1则另一个PRB的索引至少为81。在一些情况下，通信设备只要满足发送所占带宽至少为2MHz即可。
下面对非授权频谱中采用的先听后说(Listen Before Talk，LBT)机制进行说明。
在非授权频谱上，所有通信设备在发送信号前都要进行LBT。即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道监听，只有当信道监听结果为信道空闲时，该通信设备才能进行信号发送。
LBT机制包括类型1和类型2。
图2是本申请实施例提供的类型1的LBT机制的方法200的示意性流程图。需要说明的是，所述方法200可以由任意能够进行LBT的设备执行。为便于描述下面以第一设备为例进行说明，所述第一设备可以是网络设备，也可以是终端设备，本申请实施例对此不作具体限定。
如图2所示，所述方法200可包括：
S210，触发第一设备进行类型1的LBT。
S220，第一设备监听时长为Td的时间段内的信道，直到在时长为Td的时间段内监听到一个监听时隙为忙碌，或者监听到该Td的时间段内的所有的监听时隙均为空闲。
S221，若第一设备在时长为Td的时间段内监听到一个监听时隙为忙碌，第一设备不可接入信道。或者，若第一设备在时长为Td的时间段内监听到一个监听时隙为忙碌，第一设备跳转至S220。
S230，若第一设备在监听到该时间段内的所有监听时隙均为空闲，第一设备设置N＝Ninit，Ninit是从0到CW p的随机值。
S240，第一设备判断N是否等于0？
S241，若N等于0(N＝0)，表示LBT成功，所述第一设备即可占用信道并发送数据。
S250，若N不等于0(即N>0)，所述第一设备将N减1，即设置N更新为N-1。
S260，第一设备继续监听时长为一个监听时隙内的信道，若所述一个监听时隙内的信道为空闲，则跳转至S240。
S270，若所述一个监听时隙内的信道为忙碌，第一设备监听时长为Td的时间段内的信道，直到在时长为Td的时间段内监听到一个监听时隙为忙碌，或者监听到该Td的时间段内的所有的监听时隙均为空闲。具体地，若第一设备在时长为Td的时间段内监听到一个监听时隙为忙碌，重新监听时长为Td的时间段内的信道；若第一设备在监听到该时间段内的所有监听时隙均为空闲，跳转至S240。
需要说明的是，上述步骤如果没有注明跳转，则顺序执行。示例性地，上述一个监听时隙记为 Tsl，Tsl为9微秒。Ninit是从0到CW p的随机值。CW p与通信设备接入信道的优先级有关。CW p又可称为特定优先级对应的竞争窗口(Contention window)或者根据优先级确定的竞争窗口。通信设备根据接入信道的优先级确定CW min,p、CW max,p和允许的CW p的取值，即根据优先级确定竞争窗口的最小值、最大值和可能的取值。下面结合表1进行说明。
表1各个优先级对应的允许的竞争窗口
信道接入优先级(p) m p CW min,p CW max,p T mcot,p 允许的CW p取值
1 2 3 7 2ms {3,7}
2 2 7 15 4ms {7,15}
3 3 15 1023 6 or 10ms {15,31,63,127,255,511,1023}
4 7 15 1023 6 or 10ms {15,31,63,127,255,511,1023}
如表1所示，当第一设备接入信道的优先级为3时，其使用的竞争窗口的最小值、最大值和可能的取值为15、1023和{15,31,63,127,255,511,1023}。实际上，第一设备对于每一种优先级都维持着对应的竞争窗口的大小，在每次确定Ninit之前按照一定规则对每一种优先级对应的竞争窗口进行调整，然后根据信道接入的优先级，确定此次执行LBT时所使用的竞争窗口，从而确定Ninit。例如，第一设备维持着CW 1,CW 2,CW 3,CW 4，当第一设备执行类型1的LBT，在确定Ninit之前，第一设备将CW 1,CW 2,CW 3,CW 4都增加到下一个更大的允许的值，若此次第一设备接入信道的优先级是1，则第一设备使用调整后的CW 1执行此次类型1的LBT。作为示例，Td＝Tf+m p*Tsl，Tf等于16微秒，m p与信道接入的优先级相关。例如，第一设备可以从表1中根据优先级，确定对应的m p。
当第一设备执行上述步骤并且LBT成功后，如果第一设备没有马上接入信道，当其需要数据发送才接入信道时，不需要再次进行上述全部的类型1的LBT过程，只需要监听Td+至少一个Tsl时间段内的信道占用情况，如果空闲，就可以直接接入信道并发送信号。
当第一设备LBT成功，接入信道后，其占用信道的时间称为信道占用时间(Channel Occupancy Time，COT)，在COT内，第一设备可以连续传输也可以非连续传输，但总的传输时间不超过T mcot,p。T mcot,p与信道接入的优先级有关。例如，可从表1中查找T mcot,p。
与类型1不同，类型2的LBT只需要第一设备监听固定长度的信道，如果在该固定长度内监听时隙为空闲，则第一设备可以直接接入信道。具体地，类型2又分为2A,2B,2C三种子类型：
类型2A：第一设备可以监听25微秒长度(记为Tshort)的信道，如果Tshort内的监听时隙均为空闲，则第一设备可以直接接入信道。
类型2B：第一设备可以监听16微秒长度的信道(记为Tf)，如果Tf内的监听时隙为空闲，则第一设备可以直接接入信道
类型2C：第一设备可以不进行LBT直接接入信道，该类型只能应用于此次传输距离上一次传输间的间隔小于或等于16微秒的情况。同时此次传输的长度不超过584微秒。
为便于理解本申请的方案，下面针对类型1的LBT中，单播场景下的第一设备如何调整竞争窗口的方案进行说明。
上述第一设备在确定Ninit之前对每一种优先级对应的竞争窗口进行调整包括如下几种方式：
方式1：
第一设备维持各个优先级对应的竞争窗口，第一设备初始化各个优先级对应的竞争窗口为各个优先级允许的竞争窗口最小值。例如，第一设备维持CW 1,CW 2,CW 3,CW 4，并将CW 1,CW 2,CW 3,CW 4初始化为表1中各个优先级允许的竞争窗口的最小值3,7,15,15。
第一设备在确定Ninit之前，对各个优先级对应的竞争窗口进行调整。第一设备确定参考时间单元，如果参考时间单元中第一设备传输的一个或多个PDSCH对应的HARQ反馈值，至少Z％是NACK，则第一设备将各个优先级对应的竞争窗口都增加到各个优先级对应的下一个允许的值，否则，第一设备将各个优先级对应的竞争窗口设置为各个优先级允许的竞争窗口最小值。可选的，上述参考时间单元为第一设备最近一次传输占用信道的起始时间单元。示例性地，起始时间单元为起始的符号或时隙或子帧。
图3是本申请实施例提供的LBT的示意性框图。
如图3所示，第一设备维持CW 1,CW 2,CW 3,CW 4，在某一次类型1的LBT中，例如LBT 2中，确定Ninit之前，对CW 1,CW 2,CW 3,CW 4进行调整。所述第一设备上一次传输的占用信道为上一次LBT(LBT 1)成功后接入信道，因此，第一设备判断时间单元n中传输的一个或多个PDSCH对应的HARQ反馈值，若至少Z％是NACK，则增加CW 1,CW 2,CW 3,CW 4为下一个允许的值。假设CW 1,CW 2,CW 3,CW 4在调整前为3,7,15,15，则可以根据表1中的信息将CW 1,CW 2,CW 3,CW 4增加为7,15,31,31。否则，可以将CW 1,CW 2,CW 3,CW 4设置为表1各个优先级允许的竞争窗口最小值，即 3,7,15,15。
在上述维持和调整各个优先级对应的竞争窗口的过程中，对于某一个特定优先级p下的竞争窗口CW p，如果CW p已经为优先级p对应的竞争窗口的最大值，则增加CW p到下一个允许的值，依然为优先级p对应的竞争窗口的最大值。当CW p已经连续k次等于优先级p对应的竞争窗口的最大值并且用于生成Ninit，则将CW p设置为优先级p对应的竞争窗口的最小值。
方式2：
第一设备维持各个优先级对应的竞争窗口，第一设备初始化各个优先级对应的竞争窗口为各个优先级允许的竞争窗口最小值。例如，第一设备维持CW 1,CW 2,CW 3,CW 4，其初始化CW 1,CW 2,CW 3,CW 4为表1中各个优先级允许的竞争窗口的最小值3,7,15,15。
第一设备在执行上述类型1LBT中的确定Ninit之前，对各个优先级对应的竞争窗口进行调整。如果在上一次对各个优先级对应的竞争窗口进行更新后，HARQ反馈值是可获得的，例如第一设备传输了PDSCH，并获得了对应的HARQ反馈值，则第一设备根据传输的PDSCH对应的HARQ反馈值对各个优先级的竞争窗口进行调整。具体地，在上一次对各个优先级的竞争窗口进行更新后，第一设备可能多次占用信道进行传输，对于每一次占用信道的时间段，都对应一个参考时间段，例如在一般情况下，参考时间段的起点与占用信道的时间段的起点一致，终点或者为第一设备占用信道传输PDSCH的起始时隙的结束位置，或者为占用信道传输的第一组PDSCH传输机会的结束位置。上述一组PDSCH传输机会是指，一组连续的间隔小于x微秒的PDSCH传输。第一设备确定在上次更新后的一个或多个参考时间段，从中确定其中传输的PDSCH的HARQ反馈值是可获得的最近一次的参考时间段。第一设备根据确定的参考时间段内的一个或多个传输的PDSCH对应的HARQ反馈值对各个优先级的竞争窗口进行调整。
图4是本申请实施例提供的LBT的另一示意性框图。
如图4所示，第一设备进行LBT 1为类型1的LBT，在确定Ninit之前对各个优先级的竞争窗口进行更新，进行LBT 2为类型2的LBT不需要更新竞争窗口，在进行类型1的LBT 3前需对各个优先级的竞争窗口进行调整。在上一次更新后，第一设备占用了两次信道，每次占用信道都对应着一个参考时间段。在第一个参考时间段n内，第一设备传输的PDSCH对应的HARQ反馈值是可获得的，在LBT 2后的参考时间段内第一设备传输的PDSCH对应的HARQ反馈值是不可获得的。则第一设备根据参考时间段n内第一设备传输的一个或多个PDSCH对应的HARQ反馈值，调整各个优先级对应的竞争窗口。
第一设备根据确定的参考时间段内的一个或多个传输的PDSCH对应的HARQ反馈值对各个优先级的竞争窗口进行调整。具体地，如果至少一个对应的HARQ反馈值为ACK，则第一设备将各个竞争窗口的大小设置为各个优先级允许的竞争窗口的最小值。否则将各个优先级对应的竞争窗口都增加到各个优先级对应的下一个允许的更高的值。
如果第一设备在上一次更新各个优先级对应的竞争窗口之后，HARQ反馈是不可获取的，则分成以下两种情况在确定Ninit之前调整各个优先级对应的竞争窗口。如果第一设备此次进行类型1的LBT后即将发送的数据不包括重传或者此次传输距离之前占用信道的时间段对应的参考时间段的结束位置小于或等于Tw，则保持各个优先级对应的竞争窗口为之前的值，即不改变各个竞争窗口的大小。否则第一设备将各个优先级对应的竞争窗口都增加到各个优先级对应的下一个允许的值。例如图3中，第一设备在LBT 3确定Ninit之前调整各个优先级对应的竞争窗，如果此次LBT 3成功，第一设备即将发送的数据不包括重传，则第一设备不改变各个优先级对应的竞争窗口。
在上述维持和调整各个优先级对应的竞争窗口的过程中，对于某一个特定优先级p下的竞争窗口CWp，如果CWp已经为优先级p对应的竞争窗口的最大值，则增加CWp到下一个允许的值，依然为优先级p对应的竞争窗口的最大值。当CWp已经连续k次等于优先级p对应的竞争窗口的最大值并且用于生成Ninit，则将CWp设置为优先级p对应的竞争窗口的最小值。
需要说明的是，本申请提供的方案还适用于侧行(Sidelink，SL)传输。
侧行传输是指终端与终端之间通过侧行链路直接进行传输，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同。车联网系统(V2X)中也支持SL传输(V2V)的方式。因此，具有更高的频谱效率以及更低的传输时延。关于SL传输，3GPP定义了两种传输模式：模式A和模式B。
图5是本申请实施例提供的模式A的示意性框图。
如图5所示，SL UE的传输资源是由基站分配的，SL UE根据基站分配的资源在侧行链路上进行数据的发送；基站可以为SL UE分配单次传输的资源，也可以为SL UE分配半静态传输的资源。
图6是本申请实施例提供的模式B的示意性框图。
如图6所示，SL UE在资源池中选取一个资源进行数据的传输。具体的，SL UE可以通过侦听的 方式在资源池中选取传输资源，或者通过随机选取的方式在资源池中选取传输资源。
需要说明的是，本申请实施例中的SL UE即进行侧行链路传输的终端，示例性地，可以是D2D中的终端也可以是车联网中的车辆终端。
图7是本申请实施例提供的侧行传输的物理层结构的示意性框图。
如图7所示，在侧行传输中，物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)用于传输第一侧行控制信息，物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)用于承载数据和第二侧行控制信息，PSCCH和PSSCH在同一时隙中发送。第一侧行控制信息承载在PSCCH中，主要包含资源侦听相关的域，方便其他UE解码后进行资源排除与资源选择。在PSSCH中，除了数据外，还承载第二侧行控制信息，第二侧行控制信息主要包括数据解调相关的域，方便其他UE解调该PSSCH中的数据。
此外，为便于对本申请方案的理解，下面先对本申请涉及的混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈进行说明。
HARQ反馈是指收端对发端发送的数据进行解码，如果解码失败，则反馈NACK，如果解码成功则反馈ACK。发端根据收端的HARQ反馈信息决定是否进行重传。同时，收端也会对发端多次发送的数据进行合并，提升成功解码的概率。
通常，HARQ反馈方式有NACK-Only和ACK-or-NACK两种：
NACK-Only是指收端只有接收失败的时候才反馈NACK给发端，在接收成功时不反馈。
ACK-or-NACK是指收端在接收失败的时候反馈NACK给发端，在接收成功的时候反馈ACK给发端。
NACK-Only存在非连续接收(Discontinuous Reception，DRX)问题。收端在做解码时，一般都是先解码控制信息再根据控制信息中的内容解码数据。如果收端没有侦听到控制信息，则收端不会进行任何反馈。在NACK-Only的方式下，此时发端是无法判断收端是解码数据成功还是根本没有检测到控制信息。
在组播、多播以及广播场景下，发送端在同一资源上发送数据给一组接收端。
当一组接收端通过NACK-Only方式反馈HARQ信息时，可包括如下两种情况：
情况1-1：
一组接收端中的全部接收端在同一资源上反馈NACK。发送端可以根据在该资源上检测到NACK或一定数量的NACK或测量到的接收能量或功率，判断是否进行重传。
情况1-2：
一组接收端中的全部接收端分别在独立的资源上反馈NACK。发送端可以根据检测到NACK或检测到NACK的比例或检测到NACK的数量或检测到NACK的资源的数量，判断是否进行重传。
当一组接收端通过ACK/NACK方式反馈HARQ信息时，可包括如下两种情况：
情况2-1：
一组接收端中的全部接收端在同一资源上反馈ACK,在另一个资源上反馈NACK。
情况2-2：
一组接收端中的全部接收端各自在独立的资源上反馈ACK或NACK。
当一组接收端通过ACK/NACK方式反馈HARQ信息时，发送端可以根据统计出的ACK的数量或比例，或NACK的数量或比例或ACK的数量与NACK的数量的比例，判断是否进行重传。
示例性地，上述接收端用于反馈NACK或ACK的资源包括PUCCH资源或PUSCH资源或PSFCH资源。
随着通信标准的完善，第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)版本(Release)6中引入了多媒体广播多播服务(Multimedia Broadcast Multicast Service，MBMS)，在3GPP R17的版本中也正在讨论如何在NR系统中支持组播、多播和广播传输模式。组播传输模式和广播传输模式是一种通过共享网络资源从一个数据源向多个接收设备传送数据的技术，能有效地利用网络资源，并保证较高速率的传输。例如，基站通过同一个PDSCH资源将数据同时发送给所有可能收到该PDSCH的UE(广播)或者基站通过同一PDSCH资源将数据同时发送给一组UE(多播或组播)。或者说基站在某一时频资源上发送数据给目标UE组，目标UE组可能包括所有可以接收该数据的UE(广播)也可能包括一组特定UE(多播或组播)。此外，在SL中同样支持广播和组播/多播，UE可以通过同一PSSCH将数据发送给所有可能收到该PSSCH的UE(广播)，UE也可以通过同一PSSCH将数据发送给一组UE(组播)，例如这组UE可以是一定距离范围内的UE，也可以是与发送UE间存在稳定连接的UE。
虽然上文中描述了现有NR-U系统(非授权频谱上的NR系统)中，第一设备根据过去某一个时 间单元或参考时间段内传输的PDSCH对应的HARQ反馈值调整各个优先级对应的竞争窗口的方法。但在NR-U系统中目前只支持单播，也就是说，上述参考时间单元内或参考时间段内的每一个PDSCH只对应着来自一个接收端的HARQ反馈值。然而，在组播、多播以及广播的场景下，一个PDSCH将对应着来自多个接收设备的HARQ反馈值，同时也存在接收设备不对PDSCH进行反馈的情况。因此，在NR-U系统中针对单播场景的通信设备调整竞争窗口的方法不适合应用于组播、多播和广播的场景。同时，当SL系统部署在非授权频谱上，即SL-U系统中，进行组播、多播和广播的终端如何调整竞争窗口也需要相应的解决方案。
因此，针对组播、多播以及广播场景，本申请实施例提供一种无线通信方法和第一设备，不仅能够用于调整竞争窗口，还能够避免多个第一设备进行LBT时使用相同的竞争窗口，进而有利于降低多个第一设备之间的干扰。
图8是本申请实施例提供的无线通信方法300的示意性流程图，所述方法300可以由第一设备执行。例如，图1所示的网络设备，或图5或图6所示的终端设备。
如图8所示，所述方法300可包括以下部分或全部内容：

本实施例中，第一设备根据参考时间单元或参考时间段内传输的第一信道的反馈信息，调整至少一个优先级中的每一个优先级对应的竞争窗口，避免了只根据一个接收设备发送的反馈信息调整至少一个优先级中的每一个优先级对应的竞争窗口，本申请提供的方法可适用于组播、多播以及广播场景下的第一设备调整竞争窗口，例如可适用于NR-U以及SL-U下的组播、多播以及广播场景下的第一设备调整竞争窗口，能够避免多个第一设备进行LBT时使用相同的竞争窗口，有利于降低多个第一设备之间的干扰。
