Description

指示信息的传输方法和设备
交叉引用
本发明要求在2021年04月29日提交中国专利局、申请号为202110475739.8、发明名称为“指示信息的传输方法和设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请属于通信技术领域，具体涉及一种指示信息的传输方法和设备。
背景技术
终端可以在多个物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的传输过程中保持功率恒定以及相位连续，这样，网络侧设备在接收这多个PUSCH时，可以基于其中一个PUSCH的解调参考信号(DeModulation Reference Signal，DMRS)获得对于其他PUSCH的信道信息，进而使用这多个PUSCH中的DMRS进行联合信道估计，以提升接收性能，该技术可以称为DMRS绑定(bundling)。DMRS bundling也同样适用于多个物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输。
DMRS bundling要求终端在一定时间内保持功率恒定以及相位连续，且不发生任何自己的行为，对终端要求比较高，因此，终端保持功率一致性的时间不易过长。如果终端触发(如发送功率变化)破坏了功率恒定或相位连续的状态，由于网络侧设备无法知悉终端发生的状况，若网络侧设备依然进行联合信道估计将造成性能损失。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的指示信息的传输方法和设备进行详细地说明。
如图2所示，本申请实施例提供一种指示信息的传输方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。
S202：终端发送第一指示信息，第一指示信息用于指示如下至少之一：所述终端是否保持相位连续；所述终端是否保持发送功率恒定；所述终端在第一持续时间内保持相位连续和/或发送功率恒定。
该实施例可以是终端在发送第一传输的过程中执行，第一传输可以是多个PUSCH传输，还可以是多个PUCCH传输等。
关于上述第一传输可以参见图3，图3中的第一传输包括4个传输机会， 每个传输机会占用一个时隙的前5个符号。
该实施例中，第一指示信息可以包含于第一传输内；或者，第一指示信息还可以是伴随第一传输同时传输。例如，第一传输是PUSCH传输，第一指示信息可以包含在PUSCH传输内；或者，第一指示信息包含在与PUSCH关联的DMRS中，该DMRS用于网络侧设备解调PUSCH。
在一个例子中，第一指示信息用于指示终端保持相位连续和/或功率恒定。例如，在图2所示的例子中，终端在发送时隙2的第一传输时发送第一指示信息，也就是说，时隙1的第一传输和时隙2的第一传输保持相位连续和/或功率恒定，这样，网络侧设备即可对前两个时隙的第一传输进行联合信道估计，以提升接收性能，有利于覆盖能力的提升。
在另一个例子中，第一指示信息用于指示第一持续时间，终端在第一持续时间内保持相位连续和/或发送功率恒定。例如，在图2所示的例子中，终端在发送时隙1的第一传输时发送第一指示信息，第一指示信息指示第一持续时间的时间长度和起始时刻，例如，起始时刻是时隙1的起始时刻，时间长度是4个时隙，这样，网络侧设备即可对4个时隙的第一传输进行联合信道估计，以提升接收性能，有利于覆盖能力的提升。
在再一个例子中，第一指示信息用于指示终端相位不连续和/或功率不恒定。例如，在图2所示的例子中，终端在发送时隙4的第一传输时发送第一指示信息，这样，网络侧设备可以默认前三个时隙的第一传输是终端保持相位连续以及功率恒定发送的，网络侧设备可以对前三个时隙的第一传输进行联合信道估计，以提升接收性能，有利于覆盖能力的提升。
本申请实施例提供的指示信息的传输方法，终端可以向网络侧设备指示如下至少之一：终端是否保持相位连续，终端是否保持发送功率恒定，终端保持相位连续和/或发送功率恒定的第一持续时间，这样，网络侧设备即可根据终端指示进行联合信道估计，以提升接收性能，有利于覆盖能力的提升。
可选地，前文实施例提到的终端发送第一指示信息可以包括：终端在绑定时间窗口(或称bundle窗口等)内发送第一传输，且发生第一事件的情况 下，发送第一指示信息。
该实施例中，网络侧设备可以为终端配置绑定时间窗口，在该绑定时间窗口内，若终端没有发送第一指示信息，则网络侧设备可以默认终端在发送第一传输时保持相位连续以及功率恒定。
该实施例中，终端在绑定时间窗口内发送第一传输，如果检测到发生第一事件，则可以发送第一指示信息，第一事件可以包括如下1)至4)的至少之一。
1)在第一传输的传输单元之间发送了物理随机接入信道(Physical Random Access Channel，PRACH)。该传输单元可以是第一传输的一次传输机会。该例子可以参见图4，在图4所示的例子中，终端在时隙3发送了PRACH，使得时隙4的第一传输与时隙4之前的第一传输相比，相位不连续和/或功率不恒定，这样，终端即可在发送时隙4的第一传输时发送第一指示信息，第一指示信息可以用于指示终端的相位不连续和/或功率不恒定。
2)所述终端的发送功率发生变化。该例子中，第一指示信息可以用于指示终端的功率不恒定。
3)所述第一传输的预编码发生变化。该例子中，由于与编码发生变化，则可能造成终端的相位不连续和/或功率不恒定，因此，第一指示信息可以用于指示终端的相位不连续和/或功率不恒定。
4)发送了第二传输，所述第二传输与所述第一传输占用的时域资源发生重叠。该例子中，由于在发送第一传输的同时发送了第二传输，则可能造成终端的相位不连续和/或功率不恒定，因此，第一指示信息可以用于指示终端的相位不连续和/或功率不恒定。
可选地，上述提到的第二传输可以包括如下1)至4)的其中之一。
1)配置授权的PUSCH，也即配置授权(Configured grant)PUSCH。
2)终端触发的PRACH，该终端可以是执行该方法实施例的终端，也可以是其他终端。
3)PUCCH上的调度请求(Scheduling Request，SR)，也即SR on PUCCH。
4)第二小区上的上行传输；其中，所述第一传输在第一小区上传输。该例子中，第一小区和第二小区可以相同；或者，第一小区和其二小区也可以不同。在一个具体的例子中，该实施例可以应用在双连接(Dual-Connectivity，DC)的场景下，第一小区和第二小区为不同的小区组。
前文多个实施例中提到，终端在绑定时间窗口内发送第一传输，且发生第一事件的情况下，发送第一指示信息。可选地，在发生所述第一事件之后，前文各个实施例还可以包括如下步骤1)和2)之一：
1)所述终端在所述绑定时间窗口内，不再进行保持相位连续和/或功率恒定的传输。该例子中，终端在绑定时间窗口内发送第一传输，若发生第一事件，则后续的第一传输可以无需保持相位连续，也无需保持功率恒定。
2)调整发送功率，使得所述终端在第一时间单元之后的相位与所述第一时间单元之前的相位保持连续，和/或，使得所述终端在第一时间单元之后的功率与所述第一时间单元之前的功率保持恒定(或相等)；其中，所述第一事件使得所述终端在第一时间单元内的相位不连续和/或功率不恒定。该例子中，第一时间单元可以是时隙。
可选地，前文各个实施例中提到的发送第一指示信息包括如下1)和2)之一。
1)发送所述第一传输，所述第一传输包括所述第一指示信息；其中，所述第一指示信息指示的内容与第二指示信息指示的内容相反，所述第二指示信息是所述第一时间单元之后的所述第一传输包括的指示信息；其中，所述第一事件使得所述终端在所述第一时间单元内的相位不连续和/或功率不恒定。
该例子提到，第一指示信息指示的内容与第二指示信息指示的内容相反。例如，第一指示信息指示终端相位不连续，第二指示信息指示终端的相位连续，该相位连续指的是第一时间单元之后的第一传输的相位，与第一时间单元之前的第一传输的相位保持连续，后续类同；又例如，第一指示信息指示终端功率不恒定，第二指示信息指示终端的功率恒定；在例如，第一指示信 息指示终端相位不连续或功率不恒定，第二指示信息指示终端的相位连续且功率恒定。
该例子可以从第一传输的受影响的时间单元起发送1比特(bit)标记信息，放入第一传输中进行传输。其中不受影响的部分与受到影响的部分做相反标记，便于网络侧设备区分。
2)发送与所述第一传输关联的DMRS，所述DMRS包括所述第一指示信息；其中，所述第一指示信息指示的内容与第二指示信息指示的内容相反，所述第二指示信息是所述第一时间单元之后的所述DMRS包括的指示信息；其中，所述第一事件使得所述终端在所述第一时间单元内的相位不连续和/或功率不恒定。
该例子可以从第一传输的受影响的时间单元起发送1bit标记信息，整合到DMRS中进行传输。其中不受影响的部分与受到影响的部分做相反标记，便于网络侧设备区分。
上述实施例通过第一指示信息和第二指示信息，使网络侧设备可以充分对能够进行联合信道估计的部分进行联合信道估计，有利于传输性能的提升。
上述实施实例中DMRS包括的所述第一指示信息，和/或，DMRS包括的所述第二指示信息包括如下之一：
1)正交覆盖码(Orthogonal Cover Code，OCC)序列。该例子可以将OCC序列复用到DMRS序列中，不同的OCC序列来指示不同的标记信息。
该处提到的不同的标记信息可以是上述第一指示信息和第二指示信息，第一指示信息指示的内容与第二指示信息指示的内容相反，后续类同。
2)相位旋转(phase rotation)序列对。该例子可以将相位旋转序列对复用到DMRS序列中，不同的相位旋转序列对来指示不同的标记信息。该例子中的DMRS至少为2列。
3)DMRS时域位置。该例子通过不同的DMRS位置来指示不同的标记信息。
4)DMRS时域密度(或称时域pattern)。该例子通过不同的DMRS时域 密度(时域pattern)来指示不同的标记信息。
5)DMRS序列的加扰信息。该例子通过加扰不同的标识(ID)或加扰不同的序列来指示不同的标记信息。
6)生成DMRS序列的循环前缀或根序列。该例子中通过不同的循环前缀或者根序列指示不同的标记信息。
在上述实施例中，终端发送第一指示信息之后，所述方法还包括如下之一：
1)所述终端继续保持相位连续和/或功率恒定的传输，直至所述绑定时间窗口的结束位置。
2)所述终端继续保持相位连续和/或功率恒定的传输，直至再次发生所述第一事件。可以理解，再次发生的第一事件和之前发生的第一事件的具体内容可以不同，例如，之前发生的第一事件是终端发送了PRACH，再次发生的第一事件可以是终端的发送功率发生变化。
3)所述终端在所述绑定时间窗口内，不再进行保持相位连续和/或功率恒定的传输。
可选地，上述实施例还可以包括如下步骤：所述终端根据如下1)和2)的至少之一，确定所述DMRS的位置和/或所述第一指示信息复用到所述DMRS的复用方法。
1)预配置信息。该例子中，网络侧设备可以通过预配置信息指示DMRS的位置，和/或，指示第一指示信息复用到DMRS的复用方法。
2)所述第一传输的传输机会占用的时域资源的数量。例如，通过第一传输的传输机会的总符号数确定。例如，第一传输的传输机会的总符号数为5个，将OCC序列作为第一指示信息和第二指示信息；第一传输的传输机会的总符号数为4个，将相位旋转序列对作为第一指示信息和第二指示信息等等。
为详细说明本申请实施例提供的指示信息的传输方法，以下将结合几个具体的实施例进行说明。
实施例一
如图4所示，第一传输用斜线填充的符号表示，在时隙3的位置，终端触发PRACH发送，虽然没有对第一传输的时隙造成时域碰撞，但将影响第一传输的发送功率的变化，使得传输PRACH后相位不能与PRACH前保持一致。
因此，终端在发送时隙4的第一传输时可以发送第一指示信息，第一指示信息用于指示终端相位不连续。这样，网络侧设备可以对绑定时间窗口内的前3个时隙的第一传输进行联合信道估计，时隙4的第一传输进行独立的信道估计。
实施方式二
如图5所示，第一传输用斜线填充的符号表示，在第一传输的传输过程中，由于受到的路损不同或者遮挡，导致第一传输的发送功率或预编码发生变化，使得相位不能保持一致。
因此，终端在发送时隙4的第一传输时可以发送第一指示信息，第一指示信息用于指示终端相位不连续。这样，网络侧设备可以对绑定时间窗口内的前3个时隙的第一传输进行联合信道估计，时隙4的第一传输进行独立的信道估计。
实施方式三
如图6所示，第一传输和第二传输在服务小区1上进行，第二传输与第一传输在某些时隙上发生重合，这种情况下需要进行2种传输的复用问题，则不能保证第一传输的功率还和之前保持一致，从而不能再保证相位一致性传输。
因此，终端在发送时隙3的第一传输时可以发送第一指示信息，第一指示信息用于指示终端相位不连续。这样，网络侧设备可以对绑定时间窗口内的前2个时隙的第一传输进行联合信道估计，时隙3和时隙4的第一传输进行独立的信道估计。
如图7所示，如果第一传输和第二传输来自不同的小区，则第一次传输的发送功率也将发生变化，亦不能保证相位一致性的传输。
因此，终端在发送时隙3的第一传输时可以发送第一指示信息，第一指示信息用于指示终端相位不连续。这样，网络侧设备可以对绑定时间窗口内的前2个时隙的第一传输进行联合信道估计，时隙3和时隙4的第一传输进行独立的信道估计。
实施例四
如图8所示，斜线填充的符号代表此时有1bit的第一指示信息插入第一传输中。在第一指示信息插入第一传输中时，可以直接对第一传输进行速率匹配(rate matching)，或者，对第一指示信息插入的部分(第一传输的原有信息)进行替换。
该实施例中，在受到影响的时隙(时隙3)进行相应的标记传输(对应于前文实施例的第一指示信息，后续类同)，指示终端的相位不连续和/或功率不恒定，在影响结束的时隙(时隙4和时隙5)进行与之前相反的标记传输(对应于前文实施例的第二指示信息，后续类同)，指示相位连续和/或功率恒定。
这样，网络侧设备可以对绑定时间窗口内的时隙1，2，4，5的第一传输进行联合信道估计；或者，网络侧设备对绑定时间窗口内的时隙1，2的第一传输进行联合信道估计，对绑定时间窗口内的时隙4，5的第一传输进行联合信道估计。
实施例五
如图9所示，斜线填充的符号代表此时有1bit的第一指示信息插入第一传输的DMRS中。在功率或相位受到影响后，将有一组OCC序列以频域相乘的方式乘入DMRS序列中，见时隙3的位置；影响结束后，将有另一组与原OCC相位不同的序列以频域相乘的方式乘入DMRS序列中，参见图9中时隙4和时隙5的位置，以示前后相反的标记。
这样，网络侧设备可以对绑定时间窗口内的时隙1，2，4，5的第一传输进行联合信道估计；或者，网络侧设备对绑定时间窗口内的时隙1，2的第一传输进行联合信道估计，对绑定时间窗口内的时隙4，5的第一传输进行联合 信道估计。
实施例六
如图10所示，有填充的符号代表第一传输的DMRS，在受到影响后，将有一组相位对或者时域OCC以时域相乘的方式乘入序列中。由于相位对需要通过前后相位差来识别标记信息，故至少需要2组DMRS序列才能完整体现前后相反的标记。
这样，网络侧设备可以对绑定时间窗口内的时隙1，2，4，5的第一传输进行联合信道估计；或者，网络侧设备对绑定时间窗口内的时隙1，2的第一传输进行联合信道估计，对绑定时间窗口内的时隙4，5的第一传输进行联合信道估计。
实施例七
如图11所示，有填充的符号代表第一传输的DMRS，受到影响后，其位置将发生改变，网络侧设备通过预配置的一些信息知晓DMRS位置改变的含义，从而能够对这种隐式指示进行判断；在影响结束后，会改回原始的DMRS位置。
这样，网络侧设备可以对绑定时间窗口内的时隙1，2，4，5的第一传输进行联合信道估计；或者，网络侧设备对绑定时间窗口内的时隙1，2的第一传输进行联合信道估计，对绑定时间窗口内的时隙4，5的第一传输进行联合信道估计。
实施例八
如图12所示，有填充的符号代表第一传输的DMRS，受到影响后，其密度(pattern)将发生改变，网络侧设备通过预配置的一些信息知晓DMRS密度(pattern)改变的含义，从而能够对这种隐式指示进行判断；在影响结束后，会改回原始的DMRS密度(pattern)。
这样，网络侧设备可以对绑定时间窗口内的时隙1，2，4，5的第一传输进行联合信道估计；或者，网络侧设备对绑定时间窗口内的时隙1，2的第一传输进行联合信道估计，对绑定时间窗口内的时隙4，5的第一传输进行联合 信道估计。
实施例九
如图13所示，有填充的符号代表第一传输的DMRS，受到影响后，其生成的根序列，循环前缀可以发生改变，或进行不同的加扰，以期生成不同的序列；网络侧设备将根据检测结果判断此时是一种什么含义的标记。影响结束后，会恢复原有的生成方式。
这样，网络侧设备可以对绑定时间窗口内的时隙1，2，4，5的第一传输进行联合信道估计；或者，网络侧设备对绑定时间窗口内的时隙1，2的第一传输进行联合信道估计，对绑定时间窗口内的时隙4，5的第一传输进行联合信道估计。
实施例十
如图14所示，网络侧设备解析终端标记信息后，得到如图14所示的标记信息，即标记1和标记2，此时如果中间时隙间隔较小，使得可以通过网络侧设备估计相位或其他方式，让时隙间隔前后的部分相位连续起来，则网络侧设备可以选择所有相同标记的时隙做联合信道估计。
例如，图14中受影响的时隙6，其影响时间较短，使得网络侧设备能够通过相位估计补偿等方式得到相位变化值并补偿回来，则时隙4，5，7可以进行联合信道估计。
实施例十一
如图14所示，网络侧设备解析终端标记信息后，得到如图14所示的标记信息，即标记1和标记2。此时，网络侧设备可以选择相同标记的连续时隙做联合信道估计，如时隙4，5进行联合信道估计。时隙2，3是受到影响的时隙，因此可以不进行联合信道估计。
实施例十二
如图15所示，网络侧设备解析终端标记信息后，得到如图15所示的标记信息，即标记1和标记2。此时，网络侧设备可以选择相同标记的一部分单元进行联合信道估计，比如，上图中时隙4和时隙5的一部分进行联合信 道估计。
