- SSB synchronous broadcast blocks
- the LBT listen before talk
- the base station needs to transmit the SSB to the terminal, under the LBT principle, it may not be possible to transmit the SSB in the fixed position of the system because the time-frequency resources are occupied. At this time, it may try to send the SSB again at the alternate shifting transmission position (SSB shifting) allowed by the system, so that the user equipment (UE) can synchronize with the network side in time.
- SSB shifting alternate shifting transmission position
- the DRS window is a window used to send the SSB.
- the DRS window is defined as 5 ms in the related art, that is, in a scenario where the subcarrier interval is 30 kHz, the maximum number of SSBs that can be sent is 20. However, if only 1 or 2 SSBs are sent, other candidate sending positions in the DRS window will be lost when the rate is matched, which wastes system resources.
- the embodiment of the application provides a method, device, terminal, and storage medium for determining the DRS window in NR-U, which can be used to solve the problem that if only 1 or 2 SSBs are sent, other candidate sending positions in the DRS window are in rate matching.

5G(第5代移动通信***)对非授权频谱进行了立项研究,提出支持5G非授权小区单独组网的方案。在5G非授权频谱独立组网(New Radio Unlicense,NR-U)设计上,第一步就是要考虑关于同步广播块(SS/PBCH BLOCK,SSB)的设计。对于非授权频谱,需要遵守LBT(listen before talk,先听后发)原则。在基站需要向终端传输SSB时,在LBT原则下,可能因为时频资源被占用而无法在***固定配置的位置传输SSB。此时,可能在***允许的备选偏移传输位置(SSB shifting)再次尝试发送SSB,以便用户设备(UE)及时的与网络侧同步。
DRS窗口是用于发送SSB的窗口,相关技术中定义DRS窗口为5ms,也即在子载波间隔为30kHZ的场景下,可以发送的SSB最大数量是20个。但是如果只发送1或2个SSB时,DRS窗口中的其他候选发送位置在速率匹配时会被丢失掉,较为浪费***资源。

在一个示例中,DRS窗口包括两种候选的窗口长度。例如,一种窗口长度为5ms,另一种窗口长度为2.5ms。又例如,一种窗口长度为5ms,另一种窗口长度为2ms。
在一个示例中,DRS窗口包括三种以上候选的窗口长度。最大的窗口长度为5ms,其它的候选窗口长度均小于5ms且为0.5ms的倍数。例如,候选的窗口长度包括:5ms、2.5ms、2ms、1.5ms、1ms或0.5ms。
终端接收接入网设备发送的窗口暗示信息,根据该窗口暗示信息来获知DRS窗口的窗口长度。
在一个示例中,窗口暗示信息是由SSB的发送位置指示信息来隐式指示的;在另一个示例中,窗口暗示信息是由SSB的发送位置指示信息和QCL来协同隐式指示的。
步骤204,根据窗口长度接收SSB。
在确定DRS窗口的窗口长度后,在具有该窗口长度的DRS窗口中接收SSB。
在一个示例中,终端在窗口长度为5ms的DRS窗口中接收4n个或8n个SSB;在窗口长度为小于5ms的DRS窗口中接收1n个或2n个SSB。n为单个波束中发送的SSB数量,n为正整数,比如n为1。
综上所述,本实施例提供的方法,通过提供至少两种DRS窗口的窗口长度, 终端利用窗口暗示信息确定DRS在本次传输中的窗口长度,在该窗口长度中接收SSB。对于发送较多SSB的场景下,使用较大的DRS窗口;对于发送较少SSB的场景下,使用较小的DRS窗口。也即使用合理的DRS窗口发送不同数量的SSB,避免浪费***资源。
在基于图2的一个可选的实施例中,上述窗口指示信息包括SSB的发送位置指示信息,该发送位置指示信息包括第一指示域和第二指示域,当第二指示域为缺失时,确定DRS窗口的窗口长度为第一长度,第一长度是至少两种候选的窗口长度中的最大值。
示例性的,SSB的发送位置指示信息是携带在最小***剩余信息((Remaining Minimum System Information,RMSI)中的SSB-PositionInBurst信息单元(Information Element,IE)。SSB-PositionInBurst IE的定义如下
其中,SEQUENCE代表序列结构,inOneGroup为第一指示域,第一指示域为占用8个比特的位串;groupPresence为第二指示域,第二指示域为占用8个比特的位串。也即第一指示域是SSB的位置指示信息中的前8个比特,第二指示域是SSB的位置指示信息中的后8个比特。其中,第二指示域为可选信息域。
上述SSB-PositionInBurst信息单元在无线资源控制(Radio Resource Control,RRC)中的结构与上述结构略有不同(仅比特位数不同),但是同理。
其中,shortBitmap代表占用4个比特的短位图,mediumBitmap代表占用8个比特的中位图,longBitmap代表占用64个比特的长位图。
针对DRS窗口的窗口长度为两种长度的情形:
在基于图2的另一个可选的实施例中,上述窗口指示信息包括:SSB的发送位置指示信息和准共址(Quasi-Co-Location,QCL),该SSB的发送位置指示信息包括第一指示域和第二指示域。
当第二指示域为存在且QCL为1或2时,确定DRS窗口的窗口长度为第二长度,第二长度为2.5ms或2ms。
针对DRS窗口的窗口长度为三种以上的情形:
在基于图2的另一个可选的实施例中,上述窗口指示信息包括:SSB的发送位置指示信息,该SSB的发送位置指示信息包括第一指示域和第二指示域。
当第二指示域为存在时,根据第二指示域的取值确定DRS窗口的窗口长度为第三长度,是至少两种候选的窗口长度中除第一长度之外的长度,至少两种候选的窗口长度中除第一长度之外的长度均小于5ms且为0.5ms的倍数。
在一个示意性的例子中,表一示出了第二指示域的取值和DRS窗口的窗口长度的对应关系。
表一
第二指示域(groupPresence)的取值 | DRS窗口的窗口长度 |
00000001 | 4ms |
00000010 | 2.5ms |
00000011 | 2ms |
00000100 | 1ms |
上述表一仅为示例性说明,本申请对第二指示域的取值和DRS窗口的窗口长度之间的对应关系不加以限定。
图3示出了本公开一个示例性实施例提供的NR-U中DRS窗口确定方法的流程图。该方法可以由基站来执行,该方法包括:
步骤302,生成窗口暗示信息,窗口暗示信息用于隐式指示DRS窗口的窗 口长度;
DRS窗口是用于发送DRS信号的时域窗口。DRS信号包括SSB。
在一个示例中,DRS窗口包括两种候选的窗口长度。例如,一种窗口长度为5ms,另一种窗口长度为2.5ms。又例如,一种窗口长度为5ms,另一种窗口长度为2ms。
在一个示例中,DRS窗口包括三种以上候选的窗口长度。最大的窗口长度为5ms,其它的候选窗口长度均小于5ms且为0.5ms的倍数。例如,候选的窗口长度包括:5ms、2.5ms、2ms、1.5ms、1ms或0.5ms。
在一个示例中,窗口暗示信息是由SSB的发送位置指示信息来隐式指示的;在另一个示例中,窗口暗示信息是由SSB的发送位置指示信息和QCL来协同隐式指示的。
步骤304,发送窗口暗示信息;
步骤306,在具有窗口长度的DRS窗口中发送SSB;
在确定DRS窗口的窗口长度后,在具有该窗口长度的DRS窗口中发送SSB。
在一个示例中,基站在窗口长度为5ms的DRS窗口中发送4n个或8n个SSB;在窗口长度为小于5ms的DRS窗口中发送1n个或2n个SSB。n为单个波束中发送的SSB数量,n为正整数,比如n为1。
综上所述,本实施例提供的方法,通过提供至少两种DRS窗口的窗口长度,终端利用窗口暗示信息确定DRS在本次传输中的窗口长度,在该窗口长度中接收SSB。对于发送较多SSB的场景下,使用较大的DRS窗口;对于发送较少SSB的场景下,使用较小的DRS窗口。也即使用合理的DRS窗口发送不同数量的SSB,避免浪费***资源。
在基于图3的一个可选实施例中,窗口暗示信息包括:SSB的发送位置指示信息,发送位置指示信息包括第一指示域和第二指示域,第二指示域为缺失;
第二指示域,用于隐式指示DRS窗口的窗口长度为第一长度,第一长度是至少两种候选的窗口长度中的最大值。
第一指示域是SSB的位置指示信息中的前8个比特,第二指示域是SSB的位置指示信息中的后8个比特。
针对DRS窗口的窗口长度为两种长度的情形:
在基于图3的一个可选实施例中,窗口暗示信息包括:SSB的发送位置指示信息和准共址信息QCL,发送位置指示信息包括第一指示域和第二指示域。其中,第二指示域和QCL,用于隐式指示DRS窗口的窗口长度为第二长度。
示例性的,第一长度为5ms,第二长度为2.5ms或2ms。
针对DRS窗口的窗口长度为三种以上的情形:
在基于图3的一个可选实施例中,窗口暗示信息包括:SSB的发送位置指示信息,发送位置指示信息包括第一指示域和第二指示域;
第二指示域的取值,用于隐式指示DRS窗口的窗口长度为第三长度。其中,第二指示域的不同取值对应不同的第三长度,第三长度是至少两种候选的窗口长度中除第一长度之外的长度。
例如,第一长度为5ms,至少两种候选的窗口长度中除第一长度之外的长度均小于5ms且为0.5ms的倍数。
需要说明的是,在一种可能的实施例中,还可以使用SSB的发送位置指示信息中的第一指示域中的1个比特来指示DRS窗口的窗口长度为可变长度(或固定长度)。该1个比特是当前SSB在第一指示域中对应的比特。其中,当前SSB是终端接收到的携带有上述SSB-PositionInBurst的SSB。
如图4所示,第一行为第一指示域,第二行为第二指示域,一个方块表示1比特位指示信息,同时也代表着一个同步广播块对应的时频资源(以下称时隙块)。数字1表示该时频资源上有同步广播块传输,阴影表示当前接收到的同步广播块。也即,当前SSB是SSB5。
由于当前SSB是UE肯定被接收到的,因此图4所示的阴影方块的比特值可以用于隐式指示其它信息,比如该比特值为0时,代表DRS窗口支持可变长度,该比特值为1时,代表DRS窗口为固定长度。
