Description

用先听后说类型1共享信道占用时间的方法及相关装置 技术领域
本申请涉及通信技术领域，尤其涉及一种用先听后说类型1LBT CAT1共享信道占用时间COT的方法及相关装置。
背景技术
免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。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如，在一些地区，通信设备遵循“先听后说”(Listen before talk，LBT)原则，即通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。
为了保证公平性，在一次传输中，通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time，MCOT)。随着无线通信技术的发展，长期演进(Long Term Evolution，LTE)系统和第五代移动通信网络(5th generation mobile networks或5th generation wireless systems，5G)新空口(New Radio，NR)系统都会考虑在免授权频谱上布网，以利用免授权频谱来进行数据业务的传输。

此外，终端和中继设备也可以看作一个通信系统。图1中的中继设备与终端2建立链路3，中继设备可以向终端2发送下行信号，也可以接收终端2发送的上行信号。在此情况下，中继设备相对于终端而言可以视为一种网络设备。
应理解，该通信系统中包括的网络设备可以是一个或多个。一个网络设备可以向一个或多个终端发送数据或控制信令。多个网络设备也可以同时向一个或多个终端发送数据或控制信令。
目前，为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用非授权频谱必须满足的法规要求。例如，通信设备遵循“先听后说(LBT)”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。为了保证公平性，在一次传输中，通信设备使用非授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)。
在非授权载波上，对于基站获得的信道占用时间，基站可以将该信道占用时间共享给终端用于发送上行信号或上行信道。或者说，当基站将自己获得的信道占用时间共享给终端时，终端可以使用比终端自己试图获得信道时使用的优先级高的LBT方式，例如LBT类型2(LBT CAT2，，CAT为category缩写)，从而更大概率地获得信道的使用权。然而目前在NR-U里还不是很清楚在基站或者是终端分享自己的信道占用时间时可不可以用LBT类型1(LBT CAT1)。
针对上述问题，本申请实施例提出一种用先听后说类型1LBT CAT1共享信道占用时间COT的方法，下面结合附图进行详细说明。
请参阅图2，图2是本申请实施例提供的一种用先听后说类型1LBT CAT1共享信道占用时间COT的方法的流程示意图，如图所示，该方法包括：
步骤201，第一设备建立一个初始信道占用时间INIT_COT。
其中，第一设备可以使用先听后说机制获取一个非授权频段的信道，并在一定时间范围内具有该信道的使用权，例如用户设备通过LBT CAT4建立了一个初始信道占用时间INIT_COT，该INIT_COT有一个上限值，即最大信道占用时间MCOT，用户设备在进行信号传输的时长不能超过这个最大信道占用时间。
步骤202，第一设备分享所述INIT_COT给第二设备，其中，所述INIT_COT由所述第二设备用LBT CAT1得到，且所述INIT_COT用于所述第二设备在所述INIT_COT内进行数据传输，且所述数据传输的时间长度小于或等于时间长度X。
其中，分享是指所述第一设备停止传输，让给所述第二设备传输，在协议中可以通过 COT sharing来陈述该动作。
其中，LBTCAT1具体是指一种不做能量检测而只留出不超过16us的间距的机制。
具体实现中，第二设备在用LBT CAT1获得的初始信道进行传输数据时，需要遵守一定的条件，且数据传输的数据时间长度X也有一定的限制，例如可以通过发送的数据类型或时隙级别来对时间长度X进行约束。
步骤203，所述第二设备用LBT CAT1得到INIT_COT，所述INIT_COT是第一设备建立并分享给所述第二设备的。
步骤204，所述第二设备在所述INIT_COT内进行数据传输，所述数据传输的时间长度小于或等于时间长度X。
可以看出，本申请实施例中，第一设备在建立一个初始信道占用时间INIT_COT之后，会与第二设备共享该INIT_COT，第二设备用LBT CAT1得到所述INIT_COT，并在所述INIT_COT内进行数据传输，且所述数据传输的时间长度小于或等于时间长度X。可见，针对第一设备生成的NR-U中的信道的INIT_COT，第一设备和第二设备能够共享该INIT_COT，并约束传输时间长度以避免资源占用冲突，有利于提高免授权频谱NR-U的资源配置效率。
在一个可能的实例中，X为一个时间间隔的集合中的一个值或多个值；所述集合为符号级的集合，X的值为m*S，S为一个正交频分复用技术OFDM符号长度，m为正有理数；或者，所述集合为时隙级的集合，X的值为m*SL，SL为一个时隙长度，m为正有理数。
其中，若X的选择为OFDM符号级别，则X＝m*S，其中S是OFDM符号长度，m是一个正有理数。X可以是整数个符号长度，例如1到14个符号。此外，S具体可以是一个参考符号的长度，即参考符号与某一个子载波间隔绑定，例如参考符号长度是子载波间隔为15khz的对应符号长度。
其中，若X的选择为时隙(slot)级别，则X＝m*SL，其中SL是时隙长度，m是一个正有理数。X可以是整数个时隙长度，也可以是一个时隙的部分的长度，例如0.125个时隙，0.25个时隙，0.5个时隙，1个时隙等。此外，SL具体可以是一个参考时隙的长度，即参考时隙与某一个子载波间隔绑定，例如参考符号长度是子载波间隔为15khz的对应符号长度，即固定1ms。
可见，本示例中，X可以是符号级的集合或时隙级的集合中的一个值或多个值，用X来约束第二设备使用INIT_COT来传输数据的时间，可以更大限度的利用INIT_COT，保障信道资源占用的均衡。
在一个可能的实例中，S和SL的取值与子载波间隔subcarrier spacing关联。
其中，S为一个正交频分复用技术OFDM符号长度，OFDM符号的绝对长度与子载波间隔有关，子载波间隔越大，符号长度越小，SL为一个时隙长度，时隙的绝对长度与子载波间隔有关，子载波间隔越大，符号长度越小。
可见，本示例中，将S和SL的取值与子载波间隔进行关联，可以提高系统指示X的取值的灵活性。
在一个可能的实例中，X的取值与所述第二设备在INIT_COT内传输的数据类型关联。
其中，X的取值与切换点后传输的数据类型有关，可以根据传输的信号的作用划分数据类型，也可以根据传输数据的信道类型划分数据类型。
可见，本示例中，将X的取值与数据类型关联，不同的数据类型和不同的数据类型划分方式都会对X的取值造成影响，提高系统指示X的取值的灵活性。
在一个可能的实例中，所述第二设备在INIT_COT内传输的数据类型包括以下至少一种：
控制信号，所述控制信号包括由以下至少一种信道承载的信息：物理下行控制信道PDCCH以及物理上行控制信道PUCCH；
广播信号，所述广播信号包括由物理广播信道PBCH承载的信息，或者包括由物理下行共享信道PDSCH承载的系统信息；
接入信号，所述接入信号包括由物理随机接入信道PRACH承载的信息；
参考信号，所述参考信号包括以下至少一种：信道状态信息参考信号CSI-RS、信道探测参考信号SRS以及同步信号和PBCH块SSB。
其中，SSB是指在5G中将小区主辅同步信号(SS，Synchronization Signal)与物理广播信道(PBCH，Physical Broadcast Channel)进行了某种程度上的耦合，以SS/PBCH资源块的形式出现。
可见，本示例中，设备可以根据传输的数据类型来确定X的取值，提高系统指示X的灵活性。
在一个可能的实例中，X的取值与所述第二设备在INIT_COT内传输的数据类型的关联关系为：
若所述数据类型为所述SSB，则X为4个符号，即X＝4*S，或者，X为1个时隙，即X＝1*SL；
若所述数据类型为由所述PDCCH承载的信息，则X为m*S，m＝1或2或3；
若所述数据类型为由所述PUCCH承载的信息或者所述SRS，则X为m*S，m＝1或2或3或4或5或6或7或8或9或10或11或12或13或14；
若所述数据类型为由所述PDSCH承载的系统信息，则X为m*SL，m＝0.5或1。
其中，当传输的数据类型为SSB时，若X为符号级的集合，则所述符号级的集合中有4个符号，若X为时隙级的集合，则所述时隙级的集合中只有一个时隙，当数据信息由不同的信道承载时，确定X的值的有理数m会根据信道的不同而改变。
在一个可能的实例中，所述第二设备在所述INIT_COT内进行数据传输是所述第二设备在满足第一条件的情况下进行的。
可见，本示例中，用第一条件来约束第二设备使用INIT_COT进行数据传输，即可以控制切换设备的数量和切换频率，又可以充分利用初始信道占用时间。
在一个可能的实例中，所述第一条件为以下任意一种：
所述第一设备建立INIT_COT后与所述第二设备之间只存在唯一一次的切换点，所述唯一一次的切换点为在INIT_COT内只有一次传输设备切换，即由所述第一设备切换成所述第二设备；
在INIT_COT内传输设备发生大于一次切换，即所述传输设备在第一设备与所述第二设备之间存在一次以上的切换点，每一次切换后的传输设备允许传输的最大时间长度(X_post)小于或等于前一次切换后传输设备允许传输的最大时间长度(X_pre)；以及
在INIT_COT内传输设备发生切换总次数小于或等于一个最大值。
其中，切换点的个数是指在一个COT内设备之间切换COT使用权的次数。
此外，X的长度有一个最小值，即如果当网络设备或者终端再次用LBT CAT1得到COT后允许传输的长度X小于这个最小值，那么这个时候是不允许传输的。
例如，X的最小值是一个符号长度。每次切换点后的X是前一次切换点后的X的一半，即X1＝2*X2＝4*X3＝…，那么如果当第n次切换后小于一个符号，那么第n次切换不被允许。
可见，本示例中，通过切换点的个数和切换后可使用信道传输数据的时间来限制INIT_COT的共享，有利于控制切换设备的频率和最大限度的利用信道占用时间。
在一个可能的实例中，X_pre至少是X_post的两倍。
其中，当根据X_pre确定出的X_post小于一定的数值时停止切换设备。
可见，本示例中，后一次的传输最大时间长度要小于或等于前一次的最大时间长度的一半，这样可以控制切换的设备的频率和充分使用信道占用时间。
在一个可能的实例中，所述第一设备为终端，所述第二设备为网络设备；或者，所述第一设备为所述网络设备，所述第二设备为所述终端。
其中，同一个INIT_COT内的设备切换是在终端与网络设备之间切换的，终端可以用户设备例如手机，网络设备可以是NRU基站。
可见，在终端与设备之间切换INIT_COT的使用权可以使得初始信道占用时间被充分利用，以及相应的信道的利用率可以提高。
在一个可能的实例中，所述第一设备为终端，所述第二设备为网络设备；所述终端在INIT_COT内的资源为所述网络设备动态调度的资源，或者为半静态配置的资源。
其中，网络设备的动态调度通过动态资源调度器来实现，根据上下行信道的无线链路状态进行资源分配，半静态配置的资源是指网络设备每过一个周期都会使用之前指定的无线资源来接收或发送数据。
可见，本示例中，第一设备在INIT_COT内使用的资源为第二设备动态调度或半静态配置的，可以使得设备的数据传输数率得到保障。
下面结合具体示例进行详细说明。
示例1，如图2-1，图2-1是本申请提供的一种第二设备在满足条件的情况下在INIT_COT内进行数据传输的示意图，如图所示，用户设备UE是第一设备，基站gNB是第二设备，UE通过LBT CAT4得到INIT_COT并开始传输，当UE把INIT_COT分享给gNB，gNB可以在UE传输结束后开始做LBT CAT1，其中需要留不超过16us的间隙。之后gNB立即开始传输，传输的长度不得超过X，当gNB在所述INIT_COT内进行数据传输的条件是UE建立INIT_COT后与gNB之间只存在唯一一次的切换点，所述唯一一次的切换点为在INIT_COT内只有一次传输设备切换时，gNB在获得INIT_COT的使用权后，不能再把COT还给UE，即不允许多次切换点。因此在gNB传输完X长度后，INIT_COT自动结束， 即便总的INIT_COT长度还没有到达最大COT允许长度(MCOT)。
示例2，如图2-2，图2-2是本申请提供的另一种第二设备在满足条件的情况下在INIT_COT内进行数据传输的示意图，如图所示，UE是第一设备，基站gNB是第二设备，UE通过LBT CAT4得到INIT_COT开始传输，当UE把INIT_COT分享给第二设备gNB，gNB可以在UE传输结束后开始做LBT CAT1，其中需要留不超过16us的间隙。之后gNB立即开始传输，传输的长度不得超过X，当gNB在所述INIT_COT内进行数据传输的条件是所述传输设备在UE与gNB之间存在一次以上的切换点，每一次切换后的传输设备允许传输的最大时间长度小于或等于前一次切换后传输设备允许传输的最大时间长度时，可以看出，图中每一次的切换点后传输的长度X比前一个切换点后X要短，且INIT_COT内有3次切换点，第一次是UE切换给gNB。gNB用LBT CAT1得到INIT_COT后开始传输最大长度X1，然后gNB再切换给UE，此时UE再次用LBT CAT1得到INIT_COT继续传输，其传输的长度为X2(X2小于X1)，之后到了第三次切换点，gNB再次用LBT CAT1得到INIT_COT继续传输，在第三次切换点后gNB允许的最大传输长度变成了X3(X3<X2<X1)。
示例3，如图2-3，图2-3是本申请提供的再一种第二设备在满足条件的情况下在INIT_COT内进行数据传输的示意图，UE是第一设备，基站gNB是第二设备，UE通过LBT CAT4得到INIT_COT开始传输，当UE把INIT_COT分享给第二设备gNB，gNB可以在UE传输结束后开始做LBT CAT1，其中需要留不超过16us的间隙。之后gNB立即开始传输，传输的长度不得超过X，当gNB在所述INIT_COT内进行数据传输的条件是在INIT_COT内传输设备发生切换总次数小于或等于一个最大值时，切换点就可以为多个，但为了便于控制切换次数不会过于频繁，系统可以规定在这个情况下最大的切换次数，例如图2-3所示最多切换2次。
与上述图2所示的实施例一致的，请参阅图3，图3是本申请实施例提供的一种第一设备300的结构示意图，如图所示，所述第一设备300包括处理器310、存储器320、通信接口330以及一个或多个程序321，其中，所述一个或多个程序321被存储在上述存储器320中，并且被配置由上述处理器310执行，所述一个或多个程序321包括用于执行如下操作的指令。
建立一个初始信道占用时间INIT_COT；所述第一设备分享所述INIT_COT给第二设备，其中，所述INIT_COT由所述第二设备用LBT CAT1得到，且所述INIT_COT用于所述第二设备在所述INIT_COT内进行数据传输，且所述数据传输的时间长度小于或等于时间长度X。
可以看出，本申请实施例中，第一设备在建立一个初始信道占用时间INIT_COT之后，会与第二设备共享该INIT_COT，第二设备用LBT CAT1得到所述INIT_COT，并在所述INIT_COT内进行数据传输，且所述数据传输的时间长度小于或等于时间长度X。可见，针对第一设备生成的NR-U中的信道的INIT_COT，第一设备和第二设备能够共享该INIT_COT，并约束传输时间长度以避免资源占用冲突，有利于提高免授权频谱NR-U的资源配置效率。
在一个可能的示例中，X为一个时间间隔的集合中的一个值或多个值，所述集合为符 号级的集合，X的值为m*S，S为一个正交频分复用技术OFDM符号长度，m为正有理数；或者，所述集合为时隙级的集合，X的值为m*SL，SL为一个时隙长度，m为正有理数。
