Abstract

一种上行信号发送方法、上行信号接收方法、装置和系统，所述上行信号发送方法包括：终端设备在网络设备配置了与上行信号的空间关系相关的第一信息，但所述上行信号的空间关系还未生效的情况下，使用与已发送信号或已接收信号相同的空域传输滤波器或者使用所述第一信息中预定的条目所关联的空域传输滤波器发送上行信号。通过该方法，终端设备能够在根据网络设备的配置不确定上行波束的情况下使用合适的空域传输滤波器发送上行信号。

Description

上行信号发送方法、上行信号接收方法、装置和系统 技术领域
本发明涉及通信领域，特别涉及一种上行信号发送方法、上行信号接收方法、装置和系统。
背景技术
为了推进第三代合作伙伴计划第五代(3GPP 5G)标准的进展，举办了若干与该标准相关的会议。在最近的RAN1#91次会议中，关于上行控制信道(PUCCH)的波束指示机制已经确定。PUCCH资源的空间关系是由无线资源控制(RRC)信令配置的参数PUCCH-Spatial-relation-info决定。其中，PUCCH-Spatial-relation-info是一个列表，包含一个或者多个条目，每个条目可以是单边带标识(SSB ID)，信道状态信息参考信号资源指示(CSI-RS Resource Indication，CRI)或者是探测参考信号资源指示(SRS Resource Indication，SRI)，用以指示PUCCH的空间关系。如果PUCCH-Spatial-relation-info中配置了多个条目，需要媒体接入控制单元(MAC-CE)信号指示，将PUCCH的空间关系与其中的一个条目相关联，终端设备即可根据MAC-CE指示的条目所关联的PUCCH的空间关系发送上行信号；如果PUCCH-Spatial-relation-info中只包含一个条目，终端设备将直接应用其中的配置，无需使用MAC-CE信号激活。
图1a和图1b分别示出了该PUCCH-Spatial-relation-info包含多个条目和包含一个条目的情况。如图1a所示，在PUCCH-Spatial-relation-info包含多个条目(RS1～RS4)的情况下，每个条目可以具有一个编号，并且每个条目指示了一个空间关系，例如RS1指示了Tx1，RS2指示了Tx2，RS3指示了Tx3，RS4指示了Tx4，其中，RS1～RS4可以是SSB ID、CRI或者SRI。在这种配置下，网络设备通过MAC-CE来激活或指示其中一个条目，例如激活或指示RS2，由此，终端设备可以应用该RS2所指示的空间关系Tx2来发送上行信号。如图1b所示，在PUCCH-Spatial-relation-info包含一个条目(RS1)的情况下，网络设备无需进行其他配置，终端设备可以直接应用该条目RS1所指示的空间关系Tx3来发送上行信号。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、 完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，当网络设备为终端设备配置了PUCCH-Spatial-relation-info，其中PUCCH-Spatial-relation-info包含多个条目时，如图1a所示，从网络设备为终端设备配置PUCCH-Spatial-relation-info(RRC配置完成)到MAC-CE信号激活或指示其中一个条目的过程中，网络设备对于终端设备的上行波束的指示是模糊的，如图2所示，这种情况，终端设备不清楚用哪个波束上传。此外，当网络设备没有为终端设备配置PUCCH-Spatial-relation-info时，终端设备也有可能不清楚用哪个波束上传。

实施例1
本实施例提供了一种上行信号发送方法，该方法应用于终端设备。图4是本实施例的上行信号发送方法的示意图，请参照图4，该方法包括：
步骤401：终端设备在网络设备配置了与上行信号的空间关系相关的第一信息，但所述上行信号的空间关系还未生效的情况下，使用与已发送信号或已接收信号相同的空域传输滤波器或者使用所述第一信息中预定的条目所关联的空域传输滤波器发送上行信号。
在本实施例中，第一信息例如为前述的PUCCH-Spatial-relation-info，如前所述，该第一信息可以具有多个条目，也可以具有一个条目，每个条目指示或关联了一个空间关系。为了方便说明，本实施例仅针对第一信息包括多个条目的情况进行说明。
在本实施例中，如背景技术所述，在该第一信息具有多个条目的情况下，因为使用哪个条目还需要网络设备通过MAC-CE指示或激活，因此，在网络设备还未激活或指示需要使用的条目的情况下，也即该上行信号的空间关系还未生效的情况下，终端设备可以使用与已发送信号或者与已接收相同的空域传输滤波器(spatial domain transmission filter)或者使用该第一信息中预定的条目所关联的空域传输滤波器来发送上行信号。由此，终端设备能够在根据网络设备的配置不确定上行波束的情况下使用合适的空域传输滤波器发送上行信号，解决了终端设备在不确定上行波束的情况下无法发送上行信号的问题。
在其他实施例中，上行信号的空间关系还未生效也可以是其他情况，例如终端设备没有接收到网络设备的上述配置，或者，终端设备尽管接收到了网络设备的上述配置，但并没有成功获得上述第一信息，等等，在这些情况下，终端设备也可以使用与已发送信号或已接收信号相同的空域传输滤波器发送上行信号。
在本实施例中，网络设备可以通过RRC信令为终端设备配置上述第一信息，但本实施例并不以此作为限制，上述第一信息也可以通过其他信令配置。为了方便说明，本实施例以RRC信令为例，将对上述第一信息的配置称为RRC配置，这里的RRC配置不能被理解为除了配置上述第一信息以外的RRC信令的配置。
在本实施例中，上述配置可以是对第一信息的初始配置，也可以是在波束失败并 成功恢复后对该第一信息的重新配置，还可以是在小区切换成功后对该第一信息的初始配置。上述初始配置是指在此次配置之前并未为该终端设备配置过该第一信息。
图5是对第一信息(PUCCH-Spatial-relation-info)进行初始配置的示意图，如图5所示，在该场景下，终端设备可能刚刚完成了初始接入过程，从完成对第一信息的初始配置到网络设备通过MAC-CE指示或激活其中一个条目，这段时间网络设备对上行波束的指示是模糊的，称为模糊区间1，在该模糊区间1，终端设备可以使用与已发送信号或已接收信号相同的空域传输滤波器或者使用所述第一信息中预定的条目所关联的空域传输滤波器发送上行信号。
例如，终端设备可以使用与发送随机接入过程中的第一消息(msg.1)相同的空域传输滤波器发送上行信号。在图5所示的场景中，初始接入成功说明msg1的上行波束是可靠的，在以上时间段(模糊区间)中使用msg1的波束，可以保证成功率。
再例如，终端设备可以使用与发送随机接入过程中的第三消息(msg.3)相同的空域传输滤波器发送上行信号。在图5所示的场景中，与msg.1类似，初始接入成功说明msg3的上行波束是可靠的，在以上时间段(模糊区间)中使用msg3的波束，也可以保证成功率。
再例如，终端设备可以使用第一信息中预先指定的条目所关联的空域传输滤波器发送上行信号。该预先指定的条目可以是预定义或预配置的，例如预定义或预配置为第一个条目，由此，终端设备在上述模糊区间可以使用第一个条目所关联的空域传输滤波器来发送上行信号。由此，不仅解决了终端设备在上述模糊区间无法确定上行波束的问题，还减少了信令的开销。
再例如，终端设备可以使用第一信息中配置的缺省条目所关联的空域传输滤波器发送上行信号。在这个例子中，与前一个例子不同的是，网络设备还可以进一步为第一信息配置缺省条目，终端设备可以在上述模糊区间使用配置的该缺省条目所关联的空域传输滤波器发送上行信号。由此，上行波束可以有更大的选择范围，第一信息的配置会更加灵活。
再例如，终端设备可以使用与接收广播信号(PBCH)相同的空域传输滤波器发送上行信号。在这个例子中，利用了信道互易性的原理，在存在信道互易性的情况下，成功接收PBCH的空域传输滤波器所发射的相应上行波束是可靠的，终端设备可以使用该空域传输滤波器，由此可以保证成功率。
再例如，终端设备可以使用与接收同步信号(SS)相同的空域传输滤波器发送上行信号。在这个例子中，与前一个例子类似，也利用了信道互易性的原理，使用与接收SS相同的空域传输滤波器，也可以保证成功率。
此外，在图5所示的场景中，在初始配置之前，网络设备对于上行信号的空间关系(上行波束)没有任何指示，在这种情况下，网络设备对上行波束的指示也是模糊的，称为模糊区间2，在该模糊区间2，终端设备可以使用与已发送信号或已接收信号相同的空域传输滤波器发送上行信号。
例如，终端设备可以使用与发送随机接入过程中的第一消息(msg.1)相同的空域传输滤波器发送上行信号。在这个例子中，在上述初始配置之前，终端设备没有获得关于上述第一信息的配置，因此网络设备关于上行波束的指示也是模糊的，然而此时终端设备可能已经完成了初始接入，因此，在这段时间，其可以使用与发送msg.1相同的空域传输滤波器发送上行信号。同理，终端设备也可以使用与发送随机接入过程中的第三消息(msg.3)相同的空域传输滤波器发送上行信号。或者，终端设备可以使用与接收广播信号(PBCH)相同的空域传输滤波器发送上行信号，或者，终端设备可以使用与接收同步信号(SS)相同的空域滤波器发送上行信号。实施的原理与前述相同，此处省略说明。
在图5所示的场景中，上行信号可以是上行控制信号(PUCCH)，其可以用于承载下行数据信道(PDSCH)的ACK/NACK反馈，CSI上报等信息。并且，该上行信号也可以是探测参考信号(SRS)等。
图6是在波束失败并成功恢复后对该第一信息进行重新配置的示意图，如图6所示，在该场景下，终端设备刚刚从波束失败中成功恢复，原有的上行波束指示(例如对上行控制信号(PUCCH)和/或上行数据信号(PUSCH)的上行波束指示)已经不可靠，针对PUCCH和/或PUSCH的上行波束指示需要重新配置和/或激活和/或指示。由此，从成功恢复到重新配置第一信息之间，以及从重新配置第一信息到激活或指示其中一个条目之间，上行波束指示是模糊的，分别称为模糊区间3和模糊区间4。
在本实施例中，在模糊区间4，终端设备可以使用与已发送信号或已接收信号相同的空域传输滤波器或者使用所述第一信息中预定的条目所关联的空域传输滤波器发送上行信号。
例如，终端设备可以使用与发送波束失败恢复请求(BFRQ)相同的空域传输滤 波器发送上行信号。在图6所示的场景中，终端设备刚刚从波束失败中成功恢复，说明BFRQ的上行波束是可靠的，在模糊区间4使用BFRQ的波束发送上行信号，可以保证成功率。
再例如，终端设备可以使用与成功接收波束失败恢复响应控制资源集合(BFR-CORESET)相同的空域传输滤波器发送上行信号。在这个例子中，同样利用了信道互易性的原理，下行成功接收BFR-CORESET能确保上行信号的传输。
此外，终端设备也可以使用第一信息中预先指定的条目所关联的空域传输滤波器发送上行信号，或者，终端设备也可以使用第一信息中配置的缺省条目所关联的空域传输滤波器发送上行信号，或者，终端设备也可以使用与接收PBCH相同空域传输滤波器发送上行信号，或者，终端设备也可以使用与接收SS相同的空域传输滤波器发送上行信号。实施的原理与前述相同，此处省略说明。
在本实施例中，在模糊区间3，终端设备可以使用与已发送信号或已接收信号相同的空域传输滤波器发送上行信号。
例如，终端设备可以使用与发送波束失败恢复请求(BFRQ)相同的空域传输滤波器发送上行信号，或者，终端设备可以使用与成功接收波束失败恢复响应控制资源集合(BFR-CORESET)相同的空域传输滤波器发送上行信号。实施的原理与前述相同，此处省略说明。
在图6所示的场景中，由于对上述第一信息的重新配置发生在波束失败并成功恢复之后，因此需要上行波束指示的上行信号可能是PUCCH，也可能是PUSCH，或者两者都有，并且，PUCCH可以承载RRC配置响应，波束训练，波束上报等功能，PUSCH可以承载上行数据。
图7a和图7b是小区切换场景下对该第一信息进行初始配置的示意图。
在图7a所示的场景中，小区切换成功发生在对第一信息进行初始配置之前，也即，终端设备成功切换小区，在新小区完成对第一信息的初始配置，在该场景中，从小区切换完成到对第一信息的初始配置完成，以及从对第一信息的初始配置完成到网络设备激活或指示使用其中哪个条目，网络设备对上行波束的指示也是模糊的，分别称为模糊区间5和模糊区间6。
在模糊区间5，终端设备可以使用与已接收信号相同的空域传输滤波器发送上行信号。例如，终端设备可以使用与接收广播信号(PBCH)相同空域滤波器发送上行 信号，或者，终端设备可以使用与接收同步信号(SS)相同的空域传输滤波器发送上行信号。实施的原理与前述相同，此处省略说明。
在模糊区间6，终端设备可以使用与已接收信号相同的空域传输滤波器或者使用所述第一信息中预定的条目所关联的空域传输滤波器发送上行信号。例如，终端设备可以使用第一信息中预先指定的条目所关联的空域传输滤波器发送上行信号，或者，终端设备可以使用所述第一信息中配置的缺省条目所关联的空域传输滤波器发送上行信号，或者，终端设备可以使用与接收广播信号(PBCH)相同空域滤波器发送上行信号，或者，终端设备可以使用与接收同步信号(SS)相同的空域传输滤波器发送上行信号。实施的原理与前述相同，此处省略说明。
在图7b所示的场景中，小区切换成功发生在对第一信息进行初始配置之后，也即，终端设备先完成对第一信息的初始配置，再切换小区，在该场景中，从小区切换完成到到网络设备激活或指示使用其中哪个条目，网络设备对上行波束的指示也是模糊的，称为模糊区间7。
在模糊区间7，终端设备可以使用与已接收信号相同的空域传输滤波器或者使用所述第一信息中预定的条目所关联的空域传输滤波器发送上行信号。例如，终端设备可以使用第一信息中预先指定的条目所关联的空域传输滤波器发送上行信号，或者，终端设备可以使用第一信息中配置的缺省条目所关联的空域传输滤波器发送上行信号，或者，终端设备可以使用与接收广播信号(PBCH)相同空域传输滤波器发送上行信号，或者，终端设备可以使用与接收同步信号(SS)相同的空域传输滤波器发送上行信号。实施的原理与前述相同，此处省略说明。
在图7a和图7b所示的场景中，需要上行波束指示的上行信号一般为上行控制信号(PUCCH)，但本实施例并不以此作为限制，例如需要上行波束指示的上行信号也可能是SRS。
通过本实施例的方法，终端设备能够在根据网络设备的配置不确定上行波束的情况下使用合适的空域传输滤波器发送上行信号，解决了终端设备在不确定上行波束的情况下无法发送上行信号的问题。

在本实施例的一个实施方式中，与图5所示的场景类似，当上述配置为对第二信息的初始配置的情况下，由于该第二信息中仅包括一个条目，则该配置的完成即指示了上行波束。但在该配置之前，或者说，在网络设备没有给终端设备配置上述第二信息的情况下，也即在模糊区间1，网络设备对上行波束的指示仍然是模糊的，则终端设备可以使用与随机接入过程中的第一消息(msg.1)相同的空域传输滤波器发送上 行信号，或者，终端设备可以使用与随机接入过程中的第三消息(msg.3)相同的空域传输滤波器发送上行信号，或者，终端设备可以使用与接收广播信号(PBCH)相同的空域传输滤波器发送上行信号，或者，终端设备可以使用与接收同步信号(SS)相同的空域滤波器发送上行信号。实施的原理已经在实施例1中做了说明，此处不再赘述。
