  • Case 3 SS/PBCH Block or SS/PBCH Block occassion in each frequency domain adopts multiple beam directions to perform CCA detection simultaneously. If there are beams in each of the SS/PBCH Block or SS/PBCH Block occassion that detect channel idle, then a beam direction is randomly selected in the idle beam; or, the beam with the best channel state is selected; or, the channel The sub-optimal beam direction; or the beam direction in which the channel interference state is centered, or simultaneously transmitted on at least one of the detected idle beams; if only one beam is detected to be idle, the beam is transmitted. If multiple beams fail to perform CCA, the SSB or SSB occassion transmission at the frequency domain location is discarded.

For example, if the beamnei interference level satisfies the first preset threshold, or is greater than the first preset threshold, and is less than the second preset threshold, the current beam direction is considered.

Description

一种信息传输方法、装置、基站及计算机可读存储介质 技术领域
本公开涉及通信领域，尤其涉及一种信息传输方法、装置、基站及计算机可读存储介质。
背景技术
在RAN第75次会议，针对基于NR接入非授权频谱(NR-U)的SI已经完成立项，并且支持研究以下几种场景，如：NR PCell和NR-U SCell间载波聚合CA、NR PCell和NR-U PSCell间双连接DC、LTE PCell和NR-U PSCell间双连接DC及NR-U Standalone。其中，在NR PCell+NR-U SCell间CA、NR PCell+NR-U PSCell DC和LTE PCell+NR-U PSCell DC场景，可以在授权载波上进行初始接入，但是，其也需要被支持在NR非授权载波上，为了实现RRM测量目的。特别地，在NR-U Standalone中为了实现同步、测量等功能支持初始接入在NR-U已成为一个必然选择。基于此，需要研究NR-U载波上的初始接入过程，尤其是NR-U SS/PBCH Block的设计。
根据现阶段NR中关于NR-SS/PBCH Block设计已达成的共识可知，对于SCS为30kHz、120kHz，240kHz下的CaseB，CaseD，CaseE SS/PBCH Block Pattern中出现多个SS/PBCH Block连续传输情况，若多个SS/PBCH Block都采用beam方式传输时，此时，将会出现由于连续的SS/PBCH Block间没有gap而无法执行CCA检测的现象，这一定程度将影响某些beam方向上的UE进行小区同步和测量等。为了解决这个问题，一方面需要考虑设计符合非授权载波管制要求的连续SS/PBCH Block传输方法，另一方面需要考虑重新设计符合NR-U频谱特性的SS/PBCH Block时域pattern。除此之外，还需要考虑NR-SS/PBCH Block在一个5ms SS/PBCH Block时间窗内可支持的有限个SS/PBCH Block位置数目的设计并未考虑到非授权载波上LBT的因素，因此，建议考虑增加SS/PBCH Block传输机会的方法。NR-SS/PBCH Block在频域上占用20个PRB，其不满足ETSI中关于非授权频谱上占用带宽至少80％以上的管制要求，例如，对于20MHz带宽，SCS为30kHz，其SS/PBCH Block对应的频域传输带宽仅为7.2MHz。为了满足非授权载波上的占用带宽OCB问题，需要设计满足OCB的SS/PBCH Block。与此同时，还需要进一步考虑，SS/PBCH Blcok上执行CCA检测失败的异常处理方法。
针对上述问题，目前尚未有一个行之有效的信息传输机制。

可选地，可从一个子帧的角度设计SS/PBCH Block时域位置，即子帧内符号起点，和，连续符号数目，及，连续符号间间隔中至少之一确定。或者，设计1/2子帧内的SS/PBCH Block时域位置，即1/2子帧内的符号起点，和，连续符号数目，及，连续符号间间隔中至少之一确定。或者，设计1/4子帧内的SS/PBCH Block时域位置，即1/4子帧内的符号起点，和，连续符号数目，及，连续符号间间隔中至少之一确定。

情况五：对于子载波间隔为240kHz，SS/PBCH Block的起始符号索引为{#S1，#S2，#S3，#S4，#S5，#S6，#S7，#S8，#S9，#S10，#S11，#S12，#S13，#S14，#S15，#S16，#S17，#S18，#S19，#S20，#S21，#S22，#S23，#S24，#S25，#S26，#S27，#S28，#S29，#S30，#S31，#S32}+224*Nsf，或者，{#S1，#S2，#S3，#S4，#S5，#S6，#S7，#S8，#S9，#S10，#S11，#S12，#S13，#S14，#S15，#S16}+112*N””，或者，{#S1，#S2，#S3，#S4，#S5，#S6，#S7，#S8}+56*N”’，或者，{#S1，#S2，#S3，#S4}+28*N”，或者。{#S1，#S2}+14*N’。其中，Nsf子帧数，N””为半子帧数，N”’为四分之一子帧数，N”为八分之一子帧数，N’为十六分 之一子帧数。Nsf，N’，N”，N”’，N””取值为[0,[L/起点数]-1]，L为时间单元内的SS/PBCH Block的数目确定。例如，时间单元内有32个SS/PBCH Block的数目，则Nsf取值为0，N””取值为0,1，N”’取值为0,1,2,3，N”取值为0,1,2,3,4,5,6,7，N’取值为0,1,2,3,4,5,6,7，8,9,10,11,12,13,14,15。所述SS/PBCH Block时域位置可以为对应(1/n)*240kHz对应的SS/PBCH Block时域位置，或是，按照基于(1/n)子帧设计对应的SS/PBCH Block时域位置。图15为子载波间隔240kHz，1/4子帧内SS/PBCH Block时域位置示意。

实施例二：
本实施例SS/PBCH Blcok配置的SS/PBCH Blcok时域位置,或者SS/PBCH Blcok时域图样上进行传输的方法。本实施例提供的方法适用于非授权载波或频谱资源上需要竞争使用的场景。
基站只在检测信道空闲(或执行LBT成功)的SS/PBCH Block位置上进行SS/PBCH Block传输。其中，所述SS/PBCH Blcok传输基本单元为SS/PBCH Block的情况。
若在SS/PBCH Block位置上传输SS/PBCH Block之前执行LBT成功，则基站在当前SS/PBCH Block位置上传输SS/PBCH Block。若在SS/PBCH Block位置上传输SS/PBCH Block之前执行LBT失败，则基站放弃在当前SS/PBCH Block位置上传输SS/PBCH Block。
若SS/PBCH Block采用定向beam方向发送，则可采用以下方式之一处理：1)基站同时在多个定向beam方向上采用基于beam的LBT机制判定当前信道的忙闲状况。若多个定向beam方向中有至少之一beam上检测信道空闲，则在当前SS/PBCH Block位置上采用检测空闲的beam中至少之一传输SS/PBCH Block。2)基站在特定的定向beam方向上采用基于beam的LBT评估当前信道状况。若评估信道空闲，则采用当前定向beam方向传输SS/PBCH Block。若评估信道忙，则基站放弃在当前SS/PBCH Block位置上传输SS/PBCH Block。若评估信道忙的时刻未到传输SS/PBCH Block时刻，优选地，基站继续执行LBT检测，若LBT失败，则放弃当前传输。或者，基站切换beam方向，重新评估切换后beam方向内的信道状况。若LBT执行成 功，则在当前SS/PBCH Block位置上传输SS/PBCH Block。反之，LBT执行失败，则放弃传输。或，继续切换beam方向，重新评估当前beam方向上的信道状况，处理方式同上。
对于SS/PBCH Block时域位置连续或连续的SS/PBCH Block间无gap(间隔)情况，SS/PBCH Block的传输方法，包括以下至少之一：
方式一：若在当前SS/PBCH Block位置上基站执行CCA检测成功，或，评估信道空闲，则基站在当前位置上进行传输SSB。可选地，放弃或空置或不传输在下一个SS/PBCH Block位置上进行传输SSB；
若基站在当前SS/PBCH Block位置上执行CCA检测失败，或，评估信道忙，则基站放弃或空置或不传输在当前位置上进行传输SSB。基站在下一个SS/PBCH Block位置之前执行CCA检测，若执行CCA成功，或，评估信道空闲，则在当前的SS/PBCH Block位置上进行传输SSB。反之，放弃传输或不传输在当前位置；
方式二：若在当前SS/PBCH Block位置上基站在特定beam方向上执行CCA检测成功，或，评估信道空闲，则基站在连续的SS/PBCH Block位置上采用该beam方向进行SS/PBCH Block传输。若基站在当前SS/PBCH Block位置上特定beam方向上执行CCA检测失败，或，评估信道忙，则基站在放弃或不在当前SS/PBCH Block位置上传输SS/PBCH Block。继续在该beam方向上执行信道评估，若执行CCA失败，则继续执行CCA检测采用该beam方向，或，继续执行CCA检测采用切换后的beam方向。若CCA成功，则在SS/PBCH Block位置上传输SS/PBCH Block采用该beam方向，或切换后的beam方向。一旦CCA成功则在剩余的连续的SS/PBCH Block位置上传输SS/PBCH Block。依次类推采用上述方式。
方式三：若基站在当前SS/PBCH Block位置上在beam#X方向上执行CCA检测成功，或，评估信道空闲，则基站在当前SS/PBCH Block位置上采用该beam#X方向进行SSB传输。由于当前SS/PBCH Block与下一个SS/PBCH Block间无gap，则下一个SS/PBCH Block传输位置之前因无gap而不能执行CCA检测，从而放弃在下一个SS/PBCH Block位置上传输。基站可以在下下一个SS/PBCH Block位置之前在beam#X’方向上执行CCA检测。若CCA检测成功，或，评估信道空闲，则基站在当前SS/PBCH Block位置上采用beam#X’方向进行SSB传输，后续处理方式同上。
若在当前SS/PBCH Block位置上基站在beam#X方向上执行CCA失败，则基站在放弃或不在当前SS/PBCH Block位置上传输SS/PBCH Block。基站在下一个SS/PBCH Block传输位置之前采用beam#X方向或beam#X’进行CCA检测，若CCA成功则基站在当前SS/PBCH Block位置上采用beam#X方向或beam#X’方向进行SSB传输。若CCA失败，则处理方式同上。
优选地，若在CCA失败时刻未到当前SS/PBCH Block位置，则基站继续在当前beam方向执行CCA检测，或，切换beam方向执行CCA检测。
方式四：若基站在当前SS/PBCH Block位置上在beam#X1，beam#X2，...,beam#Xn方向上同时执行CCA，若多个定向beam方向中有至少之一beam上检测信道空闲，则在当前SS/PBCH Block位置上采用检测空闲的beam中至少之一传输SS/PBCH Block。其中，可以仅在当前或剩余的连续的SS/PBCH Block上传输。若多个定向beam方向上没有一个beam上检测信道空闲，则放弃在当前SS/PBCH Block位置上传输。基站在下一个SS/PBCH Block位置之前在beam#X1，beam#X2，...,beam#Xn方向上同时执行CCA，处理方式同上。若基站在当前SS/PBCH Block位置传输，则下一个SS/PBCH Block位置之前无gap，则基站不能执行CCA检测，而放弃在当前SS/PBCH Block位置上传输。基站在下下一个SS/PBCH Block位置之前执行CCA检测。其CCA检测及其处理方式同上。
优选地，对于SS/PBCH Block间无gap情况，实际传输SS/PBCH Block的位置取决于SS/PBCH Block的位置上的CCA检测结果，或，信道的忙闲状况。若当前SS/PBCH Block的位置上执行CCA成功，或，评估信道空闲，则基站在当前位置进行SS/PBCH Block传输。反之，放弃在当前位置进行SS/PBCH Block传输。
所述SS/PBCH Block传输是以SS/PBCH block occassion为基本传输单元，其中，SS/PBCH block occassion中包含M个SS/PBCH Block，所述SS/PBCH Block间可以是相互连续，或，彼此间不连续或彼此间有间隔。
对于非授权载波或是频谱资源需要竞争使用的场景，若基站执行LBT成功，则可以进行一次SS/PBCH block occassion传输，或者，进行M个SS/PBCH Block传输。SS/PBCH block occassion内的SS/PBCH block传输无需执行CCA检测或执行简化LBT机制或采用短的检测粒度的LBT机制。所述CCA检测位置为SS/PBCH block occassion位置之前。
特别地，对于SS/PBCH Block传输采用beam方式的情况，优选地，设定SS/PBCH block occassion内的SS/PBCH Block的beam方向相近或相同。基站在SS/PBCH block occassion之前在特定的beam#X方向上执行CCA检测，若CCA检测信道空闲，则在SS/PBCH block occassion内的SS/PBCH Block位置上采用beam#X方向进行SS/PBCH Block传输。若CCA检测信道忙，则放弃在SS/PBCH block occassion内的第一个SS/PBCH Block位置上传输。继续在SS/PBCH block occassion内的第二个SS/PBCH Block位置之前在特定的beam#X方向或切换后的beam#N’方向上执行CCA检测，若CCA检测信道空闲，则在当前SS/PBCH Block位置或在SS/PBCH block occassion内的剩余SS/PBCH Block位置上采用beam#X或切换后的beam#N’方向进行SS/PBCH Block传输。
或者，基站在SS/PBCH block occassion之前在beam#X1，beam#X2，...,beam#Xn方向上同时执行CCA，若多个定向beam方向中有至少之一beam上检测信道空闲，则在当前SS/PBCH block occassion内的SS/PBCH Block位置上采用检测空闲的beam 中至少之一传输SS/PBCH Block。若基站在多个定向beam方向中没有检测信道空闲beam方向，则放弃在SS/PBCH block occassion内的第一个SS/PBCH Block位置上传输。继续在SS/PBCH block occassion内的第二个SS/PBCH Block位置之前在beam#X1，beam#X2，...,beam#Xn方向上同时执行CCA，后续处理方式同上。可选地，SS/PBCH block occassion内的SS/PBCH Block的beam也不同，其处理方式参考实施例三所述方法。
另一种情况，若SS/PBCH Block时域位置连续或连续的SS/PBCH Block间有gap(间隔)情况，或，SS/PBCH block occassion中的M个SS/PBCH Block间有gap情况，在SS/PBCH Block时域位置之间的gap可用于执行CCA检测。或者，为了防止信道被占，而无法在下一个SS/PBCH Block时域位置或SS/PBCH block occassion内的其他SS/PBCH Block位置传输SS/PBCH Block。优选地，在gap的位置可以执行以下至少之一操作：执行简化的CCA检测。例如，相比于SS/PBCH block occassion CCA简化的LBT机制，或，简化的LBT参数；不执行CCA检测；或，只有当gap时长不大于预设时长的情况才不执行CCA检测；发送占用信号。其中，占用信号可以为以下至少之一：RMSI，下行参考信号，下行数据，上行控制信息，上行参考信号，测量反馈信息，上行数据。
另一种情况，引入传输SS/PBCH Block，和/或，SS/PBCH Block occassion的时间窗。例如，时间窗为一个MCOT。一个MCOT内，包含多个SS/PBCH Block或SS/PBCH Block occassion。可选地，所述SS/PBCH Block与SS/PBCH Block间，或，SS/PBCH Block occassion与SS/PBCH Block occassion间，或，SS/PBCH Block间与SS/PBCH Block occassion之间可以是连续，和/或，离散。此外，MCOT长度与非授权载波的管制要求有关。一个MCOT内包含的SS/PBCH Block和/或SS/PBCH Block occassion数目与SS/PBCH Block和/或SS/PBCH Block occassion pattern，MCOT长度，子载波间隔，载频中至少之一有关。
具体地，在MCOT开始之前基站执行CCA检测，若CCA检测成功，则基站发起一个MCOT。在MCOT内，基站在SS/PBCH Block和/或SS/PBCH Block occassion上传输SS/PBCH Block不执行CCA检测；或，执行简化的CCA检测。例如，相比于MCOT开始的CCA简化的LBT机制，或，简化的LBT参数；或，只有当gap时长不大于预设时长的情况才不执行CCA检测。MCOT外的SS/PBCH Block或SS/PBCH Block occassion传输需要执行LBT机制。
优选地，在MCOT内，若发送SS/PBCH Block或SS/PBCH Block occassion的beam方向不同时，在不同的beam方向基站需要执行LBT评估当前beam方向的信道干扰状况，从而确定当前SS/PBCH Block或SS/PBCH Block occassion上是否可以采用该beam方向或方向集合传输SSB。相同的beam方向对应的SS/PBCH Block或SS/PBCH Block occassion位置之前基站不执行CCA检测直接传输，或，执行简化的LBT机制。
实施例三：
本实施例给出连续多个SS/PBCH Block或SS/PBCH Block occasion(时机)的传输方法。其中，SS/PBCH Block occassion中包含M个SS/PBCH Block。SS/PBCH Block之间可以有gap或没有gap。
对于多个连续的SS/PBCH Block或一个SS/PBCH Block occassion(无gap)情况，其处理方式包括以下至少之一：
方式一：基站在SS/PBCH Block对应的beam方向上同时执行CCA检测，则实际传输SS/PBCH Block采用以下之一：
a、每个SS/PBCH Block在CCA检测信道空闲的beam上同时发送；
b、每个SS/PBCH Block依次采用CCA检测空闲的beam方向进行发送；
c、每个SS/PBCH Block采用CCA检测信道空闲中信道状况最好的beam方向进行发送；
d、每个SS/PBCH Block采用CCA检测信道空闲中信道状况次优的beam方向进行发送；
e、每个SS/PBCH Block采用CCA检测信道空闲中信道状况居中的beam方向进行发送；
f、若检测空闲的beam中有SS/PBCH Block对应的beam，则该SS/PBCH Block采用其对应的beam方向发送。若检测空闲的beam中没有对应SS/PBCH Block的beam方向，则在检测信道空闲的beam中随机选择一个beam方向进行发送，或，选择选择信道状态最好的beam方向发送，或，选择信道状态次优或干扰居中的beam方向进行发送。
g、当前SS/PBCH Block上基站采用CCA检测信道空闲的所有B1个beam方向上进行传输，下一个SS/PBCH Block上基站采用在CCA检测信道空闲的B1-1个beam方向上进行传输，依次类推，SS/PBCH Block在某一个beam上进行传输。其中，前一个SS/PBCH Block的发送beam中一定包含下一个SS/PBCH Block的发送beam方向。
优选地，当CCA检测信道空闲的beam数目不大于连续传输SS/PBCH Block数目时，递减到一个beam发送的SS/PBCH Block，及后续的SS/PBCH Block采用当前beam方向传输，或者，递减到一个beam发送的SS/PBCH Block之后的SS/PBCH Block的发送beam在检测信道空闲的beam中随机选一个发送，或，选择信道状态最好的beam方向发送，或，选择信道状态次优或干扰居中的beam方向进行发送。
方式二：利用新设计的能量或干扰计算方式判定当前信道是否空闲可用。若判定当前信道空闲，则采用特定beam方向进行SS/PBCH Block或SS/PBCH Block occasion的传输。
新设计的能量或干扰计算方法包括以下之一：
基站在各beam上执行CCA检测，其将各beam方向上检测到的能量之和看做当前接收到的信道能量，将其与信道空闲判决门限比较，从而确定当前信道是否空闲；或，
基站在各beam上执行CCA检测，其将各beam方向上检测到的能量的平均值看做当前接收到的信道能量，将其与信道空闲判决门限比较，从而判定当前信道是否空闲；
基站在各beam上执行CCA检测，其将各beam内检测到的能量最大值作为当前接收到的信道能量，将其与信道空闲判决门限比较，从而确定当前信道是否空闲。
基站在各beam上执行CCA检测，其将各beam内检测到的能量最小值作为当前接收到的信道能量，将其与信道空闲判决门限比较，从而确定当前信道是否空闲。
基于上述检测到的能量计算方式，若检测到的能量或干扰不大于信道空闲判决门限，则认为当前信道空闲，即可以传输连续的SS/PBCH Block或SS/PBCH Block occassion。反之，检测到的能量或干扰大于信道空闲判决门限，则认为当前信道忙，即不能传输连续的SS/PBCH Block或SS/PBCH Block occassion。或者，认为当前信道忙，仅不能传输连续的SS/PBCH Block或SS/PBCH Block occassion中的当前的SS/PBCH Block位置。下一个SS/PBCH Block上空闲信道评估方法同上，若空闲，则连续传输剩下的SS/PBCH Block或SS/PBCH Block occassion中的SS/PBCH Block。若忙，则处理方式同上。优选地，按照新设计的能量或干扰计算方法获取的干扰或能量值，其信道空闲判决门限可不同判决单beam内信道是否空闲的门限，也可以相同。
实际传输SS/PBCH Block或SS/PBCH Block occassion采用的beam按照原SS/PBCH Block或SS/PBCH Block occassion对应的beam方向进行传输；或者，选择选择信道状态最好的beam方向发送；或，选择信道状态次优或干扰居中的beam方向进行发送；或，按照各beam并集对应的beam进行传输；或，按照各beam交集对应的beam进行传输。
方式三：连续的SS/PBCH Block或SS/PBCH Block occassion中的SS/PBCH Block采用相同，或，相近的beam进行发送。
在连续的SS/PBCH Block或SS/PBCH Block occassion开始之前执行CCA检测，若CCA检测信道空闲，则连续的SS/PBCH Block或SS/PBCH Block occassion采用相同的beam进行发送。反之，在该beam方向检测信道忙，则放弃或不传输在当前SS/PBCH Block或SS/PBCH Block occassion中的当前SS/PBCH Block位置，或者，切换beam方向或采用原beam方向，重新进行CCA检测，检测信道空闲，则按照该beam方向进行连续的SS/PBCH Block或SS/PBCH Block occassion发送。反之，检测信道忙，方向切换方向继续检测。以此类推。
其中，基站可以在多个beam方向上同时执行CCA检测，其传输SS/PBCH Block或SS/PBCH Block occassion采用检测信道空闲的beam中至少之一。或者，基站在某 个特定beam方向执行CCA检测，若该beam方向上信道空闲，其传输SS/PBCH Block或SS/PBCH Block occassion采用当前特定beam方向传输。
方式四：引入双CCA判决门限方法。即利用上述三种方式中至少之一，若判定接收到能量大于第一预设门限，且小于第二预先门限，则认为当前信道空闲，可进行连续的SS/PBCH Block或SS/PBCH Block occassion发送。第一预设门限不大于第二预设门限。
SS/PBCH Block occassion之间采用不同的beam和相同beam方向处理方式一至四。
对于连续的SS/PBCH Block或SS/PBCH Block occassion间有gap情况，其处理方式与上述不同之处在于，若前后SS/PBCH Block或SS/PBCH Block occassion采用不同beam方向，则在SS/PBCH Block或SS/PBCH Block occassion间gap上基站需要执行LBT。若前后SS/PBCH Block或SS/PBCH Block occassion采用相同beam，可选地，基站可以不执行LBT，或，执行简化的LBT机制，或，直接发送占用信号。其中，占用信号可以为以下至少之一：RMSI，下行参考信号，下行数据，上行控制信息，上行参考信号，测量反馈信息，上行数据。其执行CCA或LBT的处理方式同上述方式一至四中提及的方式。
可选地，基站在第一个SS/PBCH Block或SS/PBCH Block occassion开始之前，采用第一预设门限进行CCA检测，当CCA检测信道空闲，则在当前位置传输SS/PBCH Block。若检测信道忙，则提升CCA门限，根据第二预设门限重新评定当前信道忙闲状况。或者，检测信道忙，则切换beam方向，判定当前信道状况是否满足第一预设门限，若判定空闲，则传输，反之，处理方式同上。依次类推。当第一个SS/PBCH Block传输成功或CCA执行成功，则第二SS/PBCH Block之前gap不执行CCA检测，或，执行简化的CCA检测，或，采用第二预设门限判定当前信道忙闲状况，或，发送占用信号。其中，占用信号可以为以下至少之一：RMSI，下行参考信号，下行数据，上行控制信息，上行参考信号，测量反馈信息，上行数据。
考虑到SS/PBCH Block间有gap的连续SS/PBCH Block或SS/PBCH Block occassion内各SS/PBCH Block存在发送beam方向不同情况，优选地，第一个SS/PBCH Block之后的SS/PBCH Block传输之前可执行简化的CCA检测，或，采用第二预设门限判定的CCA检测。其中，第一预设门限不大于第二预设门限。
可选地，第一个SS/PBCH Block或SS/PBCH Block occassion开始之前在预发送的各beam方向上同时执行CCA检测。若检测信道空闲的beam数目大于1个时，按照选择选择信道状态最好的beam方向发送，或，选择信道状态次优或干扰居中的beam方向进行发送，或者，评估空闲的beam中包含第一个SS/PBCH Block对应beam，则采用该beam发送SS/PBCH Block，或，在检测空闲的beam上同时传输，或，在检测空闲的beam中随机选择一个进行传输。若检测信道空闲的beam数目为1个时， 则采用该beam方向发送SS/PBCH Block。后续SS/PBCH Block传输处理方式同前一个SS/PBCH Block，或者，采用比前一个SS/PBCH Block上采用CCA检测门限更高的检测门限进行信道忙闲评估，或，采用比前一个SS/PBCH Block更简化的CCA。所述更简化的CCA包括简化的CCA机制，和/或，与CCA检测相关的参数或参数取值范围。其他处理方式与上述无gap时的处理方式类似。
实施例四：
本实施例给出增加SS/PBCH Block发送机会的具体实现方法。
对于非授权载波场景，或，频带资源需竞争使用的场景，由于LBT操作，使得设备在某些资源上的传输具有机会性特性，这一定程度上造成资源的浪费。基于此，本实施例给出增加SS/PBCH Block的方法，具体包括以下至少之一：
方式一：增加SS/PBCH Block发送时间窗内的SS/PBCH Block的位置数目。非授权载波上SS/PBCH Block发送时间窗内的SS/PBCH Block位置数目记为L’。可选地，L’＝M+Ni。M可以为授权载波上配置的SS/PBCH Block位置数目，Ni为增加量。根据不同子载波间隔，和/或，不同频带，Ni不同。
例如，对于3GHz现有NR设计5ms中配置4个SS/PBCH Block位置，NR-U中SS/PBCH Block位置数目L’为4+N1。若对于SCS为15kHz，一个子帧内有2个SS/PBCH Block位置，则N1取值范围为[0,8]，或，L’取值范围为[4,10]。若SCS为30kHz，一个子帧中有4个SS/PBCH Block位置，则N1取值范围为[0,16]，或，L’取值范围为[4,16]；对于3GHz～6GHz，5ms中配置8个SS/PBCH Block位置，NR-U中SS/PBCH Block位置数目L’为8+N2。若对于SCS为15kHz，一个子帧内有2个SS/PBCH Block位置，则N2取值范围为[0,2]，或，L’取值范围为[8,10]。若SCS为30kHz，一个子帧中有4个SS/PBCH Block位置，则N1取值范围为[0,12]，或，L’取值范围为[8,20]；对于6GHz以上，5ms中配置64个SS/PBCH Block位置，NR-U中SS/PBCH Block位置数目L’为64+N3。N1、N2、N3为大于或等于0的正整数。
所述L’、N1、N2、N3可以通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，上述任意方式组合，根据子载波间隔和/或载频确定。
其中，优选地，SS/PBCH Block发送时间窗为半个子帧，即5ms。SS/PBCH Block发送时间窗是位于SS/PBCH Block burst set中的一个半帧。SS/PBCH Block发送时间窗在SS/PBCH Block burst set内的起始位置可以是相对于SS/PBCH Block burst set开始的一个offset偏移量。Offset最小值为零。可选地最大值可以为SS/PBCH Block burst set长度-SS/PBCH Block发送时间窗长度。
方式二：增加SS/PBCH Block发送时间窗窗长。例如，授权载波中SS/PBCH Block发送时间窗窗长为5ms(即半帧)，对于非授权载波，SS/PBCH Block发送时间窗可以为不小于5ms，且不大于SS/PBCH Block burst set周期长度的正整数。SS/PBCH  Block burst set为{5ms,10ms,20ms,40ms,80ms,160ms}。所述SS/PBCH Block发送时间窗窗长通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，上述任意方式组合。
方式三：配置短周期的SS/PBCH Block burst set。一定程度上增加一定时间段内SS/PBCH Block数目。优选地，SS/PBCH Block burst set周期可以被配置(y/x)ms，1ms，2ms，3ms，4ms，5ms,10ms,20ms,40ms,80ms,160ms中之一。y不大于x，且x和y为大于0的正整数。对于小于5ms的SS/PBCH Block burst set周期，对应的SS/PBCH Block发送时间窗窗长应该不大于SS/PBCH Block burst set周期的正数。
此外，还可以采用短周期和长周期结合方式，其可以通过半静态配置，或，预定义，动态配置方式实现。
可选地，SS/PBCH Block发送时间窗外的可以配置连续的或含有gap的SS/PBCH Block位置，用于进行SSB传输。
方式四：频域上配置一个或多个SS/PBCH Block或SS/PBCH Block occassion位置。这种方式一定程度上缓解或降低因LBT导致时域资源不足的问题。优选地，频域上配置的多个SS/PBCH Block或SS/PBCH Block occassion位置采用相同，或，不同的beam方向。所述SS/PBCH Block或SS/PBCH Block occassion频域位置通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，上述任意方式组合。
对于不同频域SS/PBCH Block或SS/PBCH Block occassion位置采用相同beam的情况，包括以下情况之一：
情况一：基站同时在多个beam方向(至少包含预发送beam方向)上执行CCA检测，若检测空闲的beam方向大于1个的情况，频域上SS/PBCH Block或SS/PBCH Block occassion对应的发送beam方向可以采用以下至少之一：在空闲的beam中随机选择一个beam方向；选择信道状态最好的beam；信道状态次优的beam方向；信道干扰状态居中的beam方向；在检测空闲的beam中至少之一上同时传输。若检测空闲的beam只有一个，则频域上多个SS/PBCH Block或SS/PBCH Block occassion采用该beam进行发送。优选地，为了提高SS/PBCH Block或SS/PBCH Block occassion传输机会，可以采用比常规CCA判决门限高的门限值。
情况二：基站在待传输的SS/PBCH Block或SS/PBCH Block occassion对应的beam方向执行CCA检测，若检测空闲，则频域上发送SS/PBCH Block或SS/PBCH Block occassion的位置上采用该beam进行传输。反之，若检测忙，放弃当前传输。或者，若检测到信道忙，则基站切换到其他beam方向上执行CCA检测，若检测信道空闲，则频域上发送SS/PBCH Block或SS/PBCH Block occassion的位置上采用切换后的beam进行发送。优选地，为了提高SS/PBCH Block或SS/PBCH Block occassion传输机会，可以采用比常规CCA判决门限高的门限值。
对于不同SS/PBCH Block或SS/PBCH Block occassion频域位置对应的beam方向不同情况，包括以下之一：
情况一：基站同时在多个beam方向上执行CCA检测，CCA检测空闲beam对应的频域SS/PBCH Block或SS/PBCH Block occassion位置上可以传输SSB或SSB occassion。CCA失败的beam对应的SS/PBCH Block或SS/PBCH Block occassion位置上不进行SSB或SSB occassion传输。或者，在CCA失败beam对应的SSB或SSB occassion位置上采用检测空闲的beam方向进行发送。由于频域位置不同，从而存在相同beam对应的干扰状况不同，因此，优选地，在使用检测信道空闲的beam进行传输之前可以执行简化的CCA，或，采用比常规CCA判决门限高的门限值。
情况二：基站同时在多个beam方向上执行CCA检测，若每个beam内干扰水平满足不大于第一预设门限，或者，大于第一预设门限，且小于第二预设门限，则认为当前beam方向信道空闲。大于第一预设门限，或，大于第二预设门限，则认为当前beam方向信道忙，则放弃当前对应SSB方向的传输，或者，切换beam方向重新执行CCA检测，若beam内干扰水平满足上述条件，则认为信道空闲，反之，信道忙，放弃传输或切换beam方向重新检测，以此类推。
情况三：每个频域上SS/PBCH Block或SS/PBCH Block occassion都采用多个beam方向同时执行CCA检测的方式。每个SS/PBCH Block或SS/PBCH Block occassion上多个beam中有检测到信道空闲的beam，则在空闲的beam中随机选择一个beam方向；或，选择信道状态最好的beam；或，信道状态次优的beam方向；或，信道干扰状态居中的beam方向，或，在检测空闲的beam中至少之一上同时传输；若检测空闲的beam只有一个，则采用该beam进行发送。若多个beam都执行CCA失败，则放弃该频域位置上的SSB或SSB occassion传输。可选地，判定CCA门限可以引入双门限方式，例如，若beamnei干扰水平满足不大于第一预设门限，或者，大于第一预设门限，且小于第二预设门限，则认为当前beam方向信道空闲。若大于第一预设门限，或，大于第二预设门限，则认为当前beam方向信道忙。
实施例五：
本实施例给出SS/PBCH Block传输失败的具体处理方法。
因LBT失败或CCA检测信道忙，导致SS/PBCH Block不能传输情况，可以采用以下至少之一方式处理：
方式一：当前SS/PBCH Block或SS/PBCH Block occassion位置执行CCA失败，则基站放弃在当前SS/PBCH Block或SS/PBCH Block occassion位置上传输SSB。在所有SS/PBCH Block或SS/PBCH Block occassion传输完成后的SS/PBCH Block或SS/PBCH Block occassion位置上重新尝试发送SS/PBCH Block或SS/PBCH Block occassion。优选地，对于SS/PBCH Block或SS/PBCH Block occassion采用beam方式传输的情况，重传SS/PBCH Block或SS/PBCH Block occassion采用原beam方式进 行传输。例如，若SS/PBCH blockindex#1因LBT失败而未传输，则重新传输该SSB index(索引)时，在原beam方向上执行CCA检测，若CCA检测成功，则在当前SS/PBCH Block或SS/PBCH Block occassion上采用此beam方向传输。若CCA检测失败，则放弃当前传输。在下一个SS/PBCH Block或SS/PBCH Block occassion位置在原beam方向重新执行CCA检测，其处理方式同上。可选地，若当前CCA检测失败，则放弃当前传输。该SS/PBCH block index传输需要等所有待重传的SS/PBCH block index轮询一次后再尝试传输。
可选地，基站在重传的SS/PBCH block或SS/PBCH Block occassion位置上再待重传的beam方向同时执行CCA检测，其传输SS/PBCH block或SS/PBCH Block occassion采用检测空闲的beam中至少之一传输，或，随机选择一个beam方向；或，选择信道状态最好的beam；或，信道状态次优的beam方向；或，信道干扰状态居中的beam方向传输。
方式二：若基站在当前SS/PBCH Block或SS/PBCH Block occassion位置上执行CCA失败，则在下一个SS/PBCH Block或SS/PBCH Block occassion位置，或，SS/PBCH Block occassion中下一个SS/PBCH Block位置上重新尝试执行CCA检测，若CCA检测成功，则在当前SS/PBCH Block位置传输SS/PBCH Block，反之，在下一个SS/PBCH Block位置继续尝试发送。以此类推。优选地，对于SS/PBCH Block或SS/PBCH Block occassion采用beam方式传输的情况，重传SS/PBCH Block或SS/PBCH Block occassion采用原beam方式进行传输。
可选地，基站在重传的SS/PBCH block或SS/PBCH Block occassion位置上在待传的beam和/或重传beam方向执行CCA检测，其传输SS/PBCH block或SS/PBCH Block occassion采用检测空闲的beam中至少之一传输，或，随机选择一个beam方向；或，选择信道状态最好的beam；或，信道状态次优的beam方向；或，信道干扰状态居中的beam方向传输。
方式三：若基站在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的beam内执行CCA失败，则切换beam重新执行CCA检测。若切换的beam内检测信道空闲，则在当前位置上采用切换后的beam进行SS/PBCH Block或SS/PBCH Block occassion传输。若切换后的beam内检测信道忙或执行CCA检测失败，则切换beam重新执行CCA检测，以此类推。
方式四：若基站在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的beam内执行CCA检测失败，则在下一个SS/PBCH Block或SS/PBCH Block occassion位置采用多个beam同时执行检测方式，若当前CCA检测到原beam空闲，则采用原beam发送SS/PBCH Block或SS/PBCH Block occassion；或者，若当前CCA检测到原beam忙，则在空闲的beam中随机选择一个beam方向或选择信道状态最好的beam或信道状态次优的beam方向或信道干扰状态居中的beam方向传输；或者，在检测 到空闲的beam方向上同时发送SS/PBCH Block或SS/PBCH Block occassion。
方式五：若基站在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的beam内执行CCA检测失败，则在下一个SS/PBCH Block或SS/PBCH Block occassion位置上其他频域SS/PBCH Block或SS/PBCH Block occassion资源上尝试重新发送。可选地，其beam方向与前一个相同。如图2所示。基站同时在beam index#1和2方向上执行CCA检测，若检测到信道空闲，则采用其beam方向在当前的SS/PBCH Block或SS/PBCH Block occassion频域位置上传输。若至少一个beam内执行CCA检测失败，则处理方式同上；可选地，提升的CCA检测门限，或者，双检测检测提升CCA检测成功率。
方式六：若基站在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的beam内执行CCA检测失败，则在下一个SS/PBCH Block或SS/PBCH Block occassion位置上其他频域SS/PBCH Block或SS/PBCH Block occassion资源上尝试重新发送。优选地，当前重传SS/PBCH Block或SS/PBCH Block occassion位置上采用多个beam同时CCA检测的方式。如图3所示。基站同时在beam index#1和2，...，x方向上执行CCA检测，若在SS/PBCH Block或SS/PBCH Block occassion#3的位置上多个beam上CCA检测成功，若检测空闲的beam中包含原beam，则优选地采用原beam方向进行传输；若不包含原beam，则随机选择一个beam方向或选择信道状态最好的beam或信道状态次优的beam方向或信道干扰状态居中的beam方向传输，或者，在检测到空闲的beam方向上同时发送SS/PBCH Block或SS/PBCH Block occassion。若在SS/PBCH Block或SS/PBCH Block occassion#3的位置上所有beam上执行CCA检测失败，则放弃当前传输，在下一个时域资源上对应的频域资源上重新尝试传输，处理方式同上。若SS/PBCH Block或SS/PBCH Block occassion#3的位置上beam上CCA检测执行成功，则在当前资源上进行SS/PBCH Block或SS/PBCH Block occassion传输，反之则采用上述Beam内CCA检测失败的处理方式。
方式七：若基站在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的beam内执行CCA检测失败，则在下一个SS/PBCH Block或SS/PBCH Block occassion位置上基站需要同时在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的beam上执行CCA检测之外，还需要在前一个执行CCA检测失败的beam方向上重新执行CCA检测。若在两个beam方向上都执行CCA检测成功，则在两个beam方向上传输SS/PBCH Block或SS/PBCH Block occassion。若两个beam方向中至少有一个beam执行CCA检测失败，则在下一个SS/PBCH Block或SS/PBCH Block occassion位置基站需要同时在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的beam上执行CCA检测之外，还需要在之前执行CCA检测失败的beam方向上重新执行CCA检测。以此类推。具体处理方式如图4所示。
方式八：若基站在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的 beam内执行CCA检测失败，则下一个重新尝试重传的SS/PBCH Block或SS/PBCH Block occassion位置根据参数offset值确定。若SS/PBCH Block或SS/PBCH Block occassion采用beam方式传输，则基站在重传时频位置上再原beam方向上执行CCA检测。其中，offset可以SS/PBCH Block或SS/PBCH Block occassion位置为基准，或是，以符号为单位。Offset可以通过以下方式获取：预定义，物理层DCI信令，高层RRC信令，MAC信令，上述任意方式组合。
方式九：若基站在当前SS/PBCH Block或SS/PBCH Block occassion位置执行CCA检测失败，则在当前SS/PBCH Block或SS/PBCH Block occassion位置对应的其他频域位置上传输。优选地，基站需要同时在多个频域位置上，相同的或是不同的beam方向上执行CCA检测。基站仅在检测空闲beam对应的频域位置传输。
所述SS/PBCH Block或SS/PBCH Block occassion频域位置，或，重传SS/PBCH Block或SS/PBCH Block occassion时域位置，频域位置，beam方向中至少之一，通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，上述任意方式组合。
初传或重传SS/PBCH Block或SS/PBCH Block occassion时域位置，频域位置，beam方向中至少之一可通过物理层DCI信令，高层RRC信令，MAC信令，上述任意方式组合方式通知给UE。
实施例六：
本实施例给出SS/PBCH Block或SS/PBCH Block occassion(这里的SS/PBCH Block occassion指频域上的SSB传输occassion)满足非授权载波占用带宽管制要求的方法。
方式一：将SS/PBCH Block或SS/PBCH Block occassion作为一个整体在频域上重复n次。其中，SS/PBCH Block或SS/PBCH Block occassion在频域起点由频域偏移量确定。所述偏移量最小值可以为0，偏移的粒度以为RBG或RB或RE。SSB之间可以连续，或是，等间隔的。如图5所示。
SS/PBCH Block的频域起始位置(或频域偏移量)，SS/PBCH Block重复次数，SS/PBCH Block间隔，SS/PBCH Block的频域RB级图样通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，bitmap位图。
方式二：将SS/PBCH Block或SS/PBCH Block occassion作为一个整体与RMSI在频域上交替传输满足非授权载波占用带宽要求。其中，SS/PBCH Block或SS/PBCH Block occassion和RMSI谁前谁后均可。SS/PBCH Block或SS/PBCH Block occassion在频域起点由频域偏移量确定。所述偏移量最小值可以为0，偏移的粒度以为RBG或RB或RE。SSB之间可以连续，或是，等间隔的。如图6所示。
SS/PBCH Block的频域起始位置(或频域偏移量)，SS/PBCH Block重复次数，SS/PBCH Block间隔，RMSI的频域起始位置(或频域偏移量)，RMSI的重复次数， RMSI间间隔，SS/PBCH Block的频域RB级图样，RMSI的频域RB级图样通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，bitmap位图。
方式三：将SS/PBCH Block或SS/PBCH Block occassion作为一个整体在频域上重复n次，再在频域上重复m次RMSI。其中，SS/PBCH Block或SS/PBCH Block occassion和RMSI谁前传输n次谁后传输m次均可。SS/PBCH Block或SS/PBCH Block occassion在频域起点由频域偏移量确定。所述偏移量最小值可以为0，偏移的粒度以为RBG或RB或RE。SSB之间可以连续，或是，等间隔的。如图7所示。
SS/PBCH Block的频域起始位置(或频域偏移量)，SS/PBCH Block重复次数，SS/PBCH Block间隔，RMSI的频域起始位置(或频域偏移量)，RMSI的重复次数，RMSI间间隔，SS/PBCH Block的频域RB级图样，RMSI的频域RB级图样通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，bitmap位图。
方式四：将SS/PBCH Block或SS/PBCH Block occassion与下行信道/信号复用，满足OCB要求。其中，下行信道或信号可以位于信道的两侧，或，一侧，或，中间。图8所示，频域上重复传输n次SS/PBCH Block或SS/PBCH Block occassion，再传输下行信道或信号，从而实现占用带宽至少80％的要求。如图9所示，频域上先传输m个SS/PBCH Block或SS/PBCH Block occassion，再传输下行信道/信号，再传输SS/PBCH Block或SS/PBCH Block occassion。从而实现占用带宽至少80％的要求。
SS/PBCH Block的频域起始位置，重复次数，SS/PBCH Block间隔，SS/PBCH Block的频域RB级图样通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，bitmap位图。
方式五：将SS/PBCH Block按照一定间隔映射，最终得到SS/PBCH Block整体。假定带宽为B1，对应B2个RB，对应于B2*12个子载波，将B2*12个子载波划分为P1个簇，每个组内包含B2*12除以P1个子载波。每个簇内中含240/P1个SS/PBCH Block位置，其每次簇内对应的编号位置的240/P1个子载波上映射SS/PBCH Block。若出现带宽对应的子载波数目不能整除SS/PBCH Block占用子载波数目情况，将多出的子载波留在带宽的两侧(两侧预留的子载波为剩余载波的平均，或，不能被整除的情况下，则将大于多余子载波一半的放置低频或是高频的一侧，而另一侧在放置等于多余子载波一半的子载波)或放置低频位置，或，高频位置。
所述SS/PBCH Block的频域起始位置，RE间隔，SS/PBCH Block中子载波簇的起点，簇的结束点，簇的长度，SS/PBCH Block的频域RE图样通过以下至少之一方式确定：预定义，物理层DCI信令，高层RRC信令，MAC信令，bitmap位图。
例如，带宽为20MHz，对应100个PRB，对应1200个子载波。SS/PBCH Block频域占用20个RB，其中，第一个符号上PSS占用子载波索引#56～183，共127个子 载波，第二个符号行PBCH占用子载波索引#0～240，共240个子载波，第三个符号上SSS占用子载波索引#56～183，共127个子载波，PBCH占用子载波索引#0～48，#192～240，第四个PBCH占用子载波索引#0～240，共240个子载波。
将1200个子载波划分为240个簇，每个簇中对应索引为0，或，1，或，2，或，3，或4的位置上都可以映射SS/PBCH Block。或者，将1200个子载波划分为120个簇，每个簇里包含10个子载波，则对应的每个簇里的索引为{0，5}或，{1,6}，或{2，7}或，{3,8}，或{4，9}。或者，将1200个子载波划分为60个簇，每个簇里包含20个子载波，则对应的每个簇里的索引为{0，5,10,15}或，{1,6，11,16}，或{2，7,12,17}或，{3,8,13,18}，或{4，9,14,19}。依次类推。
归纳为：假定子载波总数为Z1，簇的个数为Z2，每个簇中包含的子载波数目为Z1/Z2所得值取整。每个簇中映射的SS/PBCH Block数目为240/Z2的所得值取值。每个簇内映射的SS/PBCH Block位置间是等间隔的。
