Description

信号发送方法、信号接收方法及装置 技术领域
本发明涉及通信领域，尤其涉及一种信号发送方法、信号接收方法及装置。
背景技术
在高频通信场景下，通信链路容易受到物理条件，例如天气、障碍物、方向角度的变化等因素的影响，从而造成在原有的波束方向上传输失败的情况。波束失败恢复(BFR，Beam Failure Recovery)技术主要针对这种场景，利用对不同方向波束功率的测量结果，迅速定位新的可靠的波束方向，从而完成对链路的快速恢复。
波束失败恢复技术不仅在单载波场景非常有效，而且在多载波场景也能发挥重要的作用。在多载波场景下，终端设备(TE，Terminal Equipment)可以与一个网络设备(例如基站)或者多个网络设备相连接。当一个终端设备的不同载波同时与不同方向的网络设备连接时，由于空间方向相对独立，在某一时刻，该不同的载波上的连接可能仅有一部分发生波束失败。在该情况下，波束失败恢复技术有必要针对这种场景进行优化，例如，利用未发生波束失败的载波进行参数测量、数据传递等，从而提高系统的鲁棒性。
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
目前，5G-NR(5G-New Radio)通信系统中，当波束失败恢复过程成功之后，上行传输所使用的空间传输滤波器(Spatial Domain Transmission Filter)依然是波束失败恢复之前配置的。由于上下行传输的互异性，当下行信道发生了波束失败后，对应的上行信道大概率也会发生失败。这意味着，终端设备按照原有的空间配置发送上行信号是不可靠的。
本发明实施例提供一种信号发送方法、信号接收方法及装置，终端设备在接收到 与波束失败恢复相关的下行信号的一段时间之后且在接收到或应用激活信令或重配置信令之前的时间区间内，使用和发送与波束失败恢复相关的上行信号或接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号，从而提供了一种终端设备在波束失败恢复成功之后使用空域传输滤波器发送上行信号的解决方案，提高了终端设备发送上行信号的可靠性。另外，该解决方案的适用性较广，其不仅适用于特殊小区(SpCell，Special Cell)发生波束失败的场景，也适用于辅小区(SCell，Secondary Cell)发生波束失败的场景。在多载波(多服务小区被配置的)场景下，该解决方案可以正确的指示所述第一小区的上行信号所使用的空域传输滤波器，避免错误的指示其他的小区(非所述第一小区)的上行信号所使用的空域传输滤波器。
另外，本解决方案还对所述一段时间的起始点进行了精确的规定，避免了终端设备和网络设备对所述一段时间理解不一致而产生的不必要的收发错误。

实施例1
本发明实施例提供一种信号方法，该方法应用于终端设备侧。
图2是本发明实施例1的信号发送方法的一示意图。如图2所示，该方法包括：
步骤201：终端设备在接收到与波束失败恢复相关的下行信号的一段时间之后，并且在接收到或应用激活信令或重配置信令之前，使用和发送与波束失败恢复相关的上行信号或接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号。
这样，提供了一种终端设备在波束失败恢复成功之后使用空域传输滤波器发送上行信号的解决方案，提高了终端设备发送上行信号的可靠性。另外，该解决方案的适用性较广，其不仅适用于SpCell发生波束失败的场景，也适用于辅小区(SCell，Secondary Cell)发生波束失败的场景。在多载波(多服务小区被配置的)场景下，该解决方案可以正确的指示所述第一小区的上行信号所使用的空域传输滤波器，避免错误的指示其他的小区(非所述第一小区)的上行信号所使用的空域传输滤波器。
另外，本解决方案还对所述一段时间的起始点进行了精确的规定，避免了终端设备和网络设备对所述一段时间理解不一致而产生的不必要的收发错误。
在步骤201中，终端设备在接收到与波束失败恢复相关的下行信号的一段时间之后且在接收到或应用激活信令或重配置信令之前的时间区间内，使用和发送与波束失败恢复相关的上行信号或接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号。
也就是说，终端设备在接收到与波束失败恢复相关的下行信号的一段时间之后，在需要发送在第一小区的上行信号的情况下，使用和发送与波束失败恢复相关的上行信号或接收下行参考信号的空域传输滤波器相同的空域传输滤波器来发送该上行信号，直到该终端设备接收到或应用激活信令或重配置信令。
或者，也就是说，终端设备在接收到与波束失败恢复相关的下行信号之后，如果接收所述与波束失败恢复相关的下行信号的时刻与所述终端设备发送所述上行信号的时刻的偏移(offset)大于或等于一段时间，则使用和发送与波束失败恢复相关的上行信号或接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一 小区的上行信号，直到终端设备接收到或应用激活信令或重配置信令。
在本实施例中，终端设备在接收到或应用激活信令或重配置信令之后，不再受到步骤201中的关于空域传输滤波器的使用限制。
在本实施例中，为了便于说明，将“接收到与波束失败恢复相关的下行信号”的时刻称为第一时刻，将“接收到与波束失败恢复相关的下行信号的一段时间”的时刻称为第二时刻，将“接收到或应用激活信令或重配置信令”的时刻称为第三时刻，将“发送在第一小区的上行信号”的时刻称为第四时刻。那么，在步骤201中，终端设备在所述第二时刻和所述第三时刻之间的时间区间内，使用上述规定的空域传输滤波器，发送在第一小区的上行信号。或者，也可以理解为，终端设备在所述第一时刻与所述第四时刻的偏移(offset)大于或等于一段时间，且在第三时刻之前，使用上述规定的空域传输滤波器，发送在第一小区的上行信号。
下面，首先对步骤201中的“接收到与波束失败恢复相关的下行信号的一段时间”进行示例性的说明。
在本实施例中，该与波束失败恢复相关的下行信号是网络设备向用户设备发送的与波束失败恢复相关的下行信号，例如，该与波束失败恢复相关的下行信号是波束失败恢复响应和/或波束失败恢复响应所调度的下行数据信息。
在本实施例中，该波束失败恢复响应可以是在由高层参数提供的搜索空间上接收的、由小区无线网络临时标识(C-RNTI，Cell Radio Network Temporary Identifier)或调制与编码策略小区无线网络临时标识(MCS-C-RNTI，Modulation and Coding Scheme-Cell Radio Network Temporary Identifier)加扰的下行控制信息(DCI，Downlink Control Information)。
在本实施例中，该高层参数可以由无线资源控制(RRC，Radio Resource Control)信令配置。
在本实施例中，该高层参数可以用于配置接收波束失败恢复(BFR)随机接入响应(RAR，Random Access Response)的搜索空间集合(set)。
例如，该高层参数是恢复搜索空间集合标识(recoverySearchSpaceId)。
在本实施例中，该“一段时间”可以根据实际需要而设定。
例如，该一段时间可以是预设数量的符号(symbol)、时隙(slot)或毫秒(msec)。
例如，该一段时间是K个符号，或者，K个时隙，或者，K毫秒，其中，K是大 于或等于0的整数。
在本实施例中，该一段时间的长度可以与子载波间隔(SCS，subcarrier spacing)相关。
例如，该一段时间的长度在不同的子载波间隔下，会发生变化。
例如，该一段时间的长度所对应的符号数可以正比于SCS，即，该SCS为15KHz时，该一段时间的长度为14个符号；该SCS为30KHz时，该一段时间的长度为28个符号；该SCS为60KHz时，该时间长度为56个符号，以此类推。
再例如，在该SCS为15kHz和30kHz时使用第一时间长度(例如14个符号)，在该SCS高于30kHz的情况下，使用第二时间长度(例如28个符号)。
在本实施例中，该一段时间的长度也可以与该终端设备的能力(UE capability)相关。具体的说，该终端设备的能力指的是上报给网络设备的终端设备的能力。
例如，该一段时间的长度在不同终端设备能力的等级下，会发生变化。
例如，在第一UE能力等级(或上报了第一UE能力等级的信息)的情况下，该一段时间的长度为第一时间长度(例如14个符号)；在第二UE能力等级(或上报了第二UE能力等级的信息)的情况下，该一段时间的长度为第二时间长度(例如28个符号)，以此类推。
在本实施例中，该一段时间的长度可以是被高层信令配置的。
在本实施例中，所述一段时间也可以理解为一个阈值，当所述第一时刻与所述第四时刻的偏移大于或等于所述阈值时，且在第三时刻之前，所述终端设备使用上述规定的空域传输滤波器，发送在第一小区的上行信号。
其中，所述第一时刻，即接收到与波束失败恢复相关的下行信号的时刻，可以进一步的理解为：
例如，下行信号是所述波束失败恢复响应，那么，接收到下行信号的时刻即是接收该下行信号所在的时隙；或者，下行信号是所述波束失败恢复响应，接收到下行信号的时刻即是接收该下行信号所在的时隙的第一个或最后一个符号；或者，下行信号是所述波束失败恢复响应，那么，接收到下行信号的时刻即是接收该波束失败恢复响应(的搜索空间)所对应的控制资源集合(control resource set)的一个符号(第一个符号/最后一个符号)；
再例如，下行信号是所述波束失败恢复响应所调度的下行数据信息(例如，单时 隙PDSCH，或多时隙PDSCH的其中一个时隙的PDSCH)，那么，接收到下行信号的时刻即是接收该下行信号所在的时隙；或者，下行信号是所述波束失败恢复响应所调度的下行数据信息(例如，PDSCH)，如果终端设备配置了单时隙PDSCH(single slot PDSCH)，即配置的PDSCH重复次数为1(aggregationFactorDL＝1)，那么，接收到下行信号的时刻即是该下行数据信息所在的时隙；再或者，下行信号是所述波束失败恢复响应所调度的下行数据信息(例如，PDSCH)，如果终端设备配置了多时隙PDSCH(multiple slot PDSCH)，即配置的PDSCH重复次数大于1(aggregationFactorDL>1)，那么，接收到下行信号的时刻即是该下行数据信息相关的时隙(例如，下行数据信息相关的时隙是该下行数据信息(包括多个时隙的PDSCH)的第一个时隙，或是该下行数据信息(包括多个时隙的PDSCH)的最后一个时隙)。
再例如，下行信号是所述波束失败恢复响应所调度的下行数据信息(例如，单时隙PDSCH，或多时隙PDSCH的其中一个时隙的PDSCH)，那么，接收到下行信号的时刻即是该下行数据信息相关的符号(例如，该下行数据信息相关的符号是该下行信号所对应的第一个符号，或是该下行信号所对应的最后一个符号)；或者，下行信号是所述波束失败恢复响应所调度的下行数据信息(例如，PDSCH)，如果终端设备配置了单时隙PDSCH(single slot PDSCH)，即配置的PDSCH重复次数为1(aggregationFactorDL＝1)，那么，接收到下行信号的时刻即是承载该下行数据信息的资源(PDSCH)的第一个或最后一个符号；再或者，下行信号是所述波束失败恢复响应所调度的下行数据信息(例如，PDSCH)，如果终端设备配置了多时隙PDSCH(multiple slot PDSCH)，即配置的PDSCH重复次数大于1(aggregationFactorDL>1)，那么，接收到下行信号的时刻即是该下行数据信息相关的符号(例如，该下行数据信息相关的符号是该下行信号(包括多个时隙的PDSCH)的第一个时隙的PDSCH的第一个符号，或是该下行信号(包括多个时隙的PDSCH)的最后一个时隙的PDSCH的最后一个符号)。
其中，所述第四时刻，即发送在第一小区的上行信号的时刻，可以进一步的理解为：
例如，上行信号是指上行控制信息(PUCCH)，那么，发送在第一小区的上行信号的时刻，即是发送在第一小区的上行控制信息所在的时隙；或者，上行信号是指上行控制信息(PUCCH)，那么，发送在第一小区的上行信号的时刻，即是发送在第一 小区的上行控制信息相关的符号(例如，该上行控制信息的第一个符号或最后一个符号；再例如，发送在第一小区的上行控制信息所在的时隙的第一个符号或最后一个符号)；
再例如，上行信号是指上行数据信息(例如，单时隙PUSCH，或多时隙PUSCH的其中一个时隙的PUSCH)，那么，发送在第一小区的上行信号的时刻，即是发送在第一小区的上行信号所在时隙；或者，上行信号是指上行数据信息(PUSCH)，那么，如果终端设备配置了单时隙PUSCH(single slot PUSCH)，即配置的PUSCH重复次数等于1(repK＝1)，发送在第一小区的上行信号的时刻，即是发送在第一小区的上行数据信息所在的时隙；或者，上行信号是指上行数据信息(PUSCH)，那么，如果终端设备配置了多时隙PUSCH(multiple slot PUSCH)，即配置的PUSCH重复次数大于1(repK>1)，发送在第一小区的上行信号的时刻，即是发送在第一小区的上行数据信息相关的时隙(例如，发送在第一小区的上行数据信息(包括多个时隙的PUSCH)的第一个时隙或最后一个时隙)；
再例如，上行信号是指上行数据信息(例如，单时隙PUSCH，或多时隙PUSCH的其中一个slot的PUSCH)，那么，发送在第一小区的上行信号的时刻，即是发送在第一小区的上行数据信息相关的符号(例如，该上行数据信息相关的符号即是该上行数据信息的第一个符号或最后一个符号)；或者，上行信号是指上行数据信息(PUSCH)，那么，如果终端设备配置了单时隙PUSCH(single slot PUSCH)，即配置的PUSCH重复次数等于1(repK＝1)，发送在第一小区的上行信号的时刻，即是承载该上行数据信息的资源的第一个符号或最后一个符号；或者，上行信号是指上行数据信息(PUSCH)，那么，如果终端设备配置了多时隙PUSCH(multiple slot PUSCH)，即配置的PUSCH重复次数大于1(repK>1)，发送在第一小区的上行信号的时刻，即是发送在第一小区的上行数据信息相关的符号(例如，发送在第一小区的上行数据信息(包括多个时隙的PUSCH)的第一个时隙PUSCH的第一个符号或最后一个时隙PUSCH的最后一个符号)。
其中，所述第三时刻，即接收到或应用激活信令或重配置信令的时刻，可以进一步的理解为：
例如，接收到或应用激活信令或重配置信令的时刻是应用所述激活信令或重配置信令的时刻，更具体的说是所述激活信令或重配置信令生效的时隙；或者，接收到或 应用激活信令或重配置信令的时刻是接收到激活信令或重配信令所对应的下行信号(例如，单时隙PDSCH，或多时隙PDSCH的其中一个时隙的PDSCH)所在的时隙；再或者，如果终端设备配置了单时隙PDSCH(single slot PDSCH)，即配置的PDSCH重复次数为1(aggregationFactorDL＝1)，则接收到或应用激活信令或重配置信令的时刻是接收到激活信令或重配信令所对应的PDSCH所在的时隙；再或者，如果终端设备配置了多时隙PDSCH(multiple slot PDSCH)，即配置的PDSCH重复次数大于1(aggregationFactorDL>1)，则接收到或应用激活信令或重配置信令的时刻是接收到激活信令或重配信令所对应的下行信号(包括多时隙的PDSCH)的第一个或最后一个时隙。
下面，对步骤201中的“接收到或应用激活信令或重配置信令”进行示例性的说明。
在本实施例中，该激活信令也可以是一种指示信令。
例如，该激活信令可以是以下的至少一个：
介质访问控制(MAC，Media Access Control)层的激活信令；
指示该终端设备天线面板切换的信令；以及
目标小区是该第一小区的激活信令。
例如，该MAC层的激活信令用于指示至少一个已配置的PUCCH资源的发送所对应的空域传输滤波器，例如该激活信令指示的是PUCCH-SpatialRelationInfo。
在本实施例中，该重配置信令可以是以下的至少一个：
RRC信令；
与该终端设备天线面板相关的重配置信令；以及
目标小区是该第一小区的重配置信令。
例如，该RRC信令重配置了至少一个已配置的物理上行链路控制信道(PUCCH，Physical Uplink Control Channel)资源所关联的空间关系参数。
例如，该空间关系参数是PUCCH-SpatialRelationInfo。
以上对“接收到与波束失败恢复相关的下行信号的一段时间”和“接收到或应用激活信令或重配置信令”进行了示例性的说明，下面，对步骤201中的“使用和发送与波束失败恢复相关的上行信号或接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号”进行示例性的说明。
在本实施例中，该与波束失败恢复相关的上行信号可以是以下的至少一种信号：
波束失败恢复请求；
为了链路失败恢复的物理随机接入信道(PRACH)发送(transmission)；以及
与所述与波束失败恢复相关的下行信号相关联的物理随机接入信道(PRACH)发送(transmission)。具体的说，所述物理随机接入信道(PRACH)发送(transmission)和所述与波束失败恢复相关的下行信号可以是时间的关联，例如，在时隙n进行所述物理随机接入信道(PRACH)发送(transmission)，在时隙n+4接收相应的所述与波束失败恢复相关的下行信号(为了波束失败恢复的随机接入响应)。
在本实施例中，该与波束失败恢复相关的上行信号可以是由高层参数配置的。
在本实施例中，该高层参数可以由RRC信令承载。更具体地说，该高层参数可以用于配置波束失败恢复(BFR)专用的发送该与波束失败恢复相关的上行信号的资源。例如，该高层参数为PRACH-ResourceDedicatedBFR。
在本实施例中，该下行参考信号可以是该第一小区的下行参考信号。
在本实施例中，该下行参考信号的索引可以由MAC层的信令提供。例如，该下行参考信号的索引是由MAC层从高层参数中选出的。
例如，该下行参考信号的索引为q new，MAC层实体从RRC层参数中选出q new。例如，该RRC层参数为表示候选波束参考信号列表的参数candidateBeamRSList。
在步骤201中，当发送该与波束失败恢复相关的上行信号所在的第二小区与该第一小区是同一小区时，使用和发送与波束失败恢复相关的上行信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号；当发送该与波束失败恢复相关的上行信号所在的第二小区与该第一小区不是同一小区时，使用和接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号。
图3是本发明实施例1的信号发送方法的另一示意图。如图3所示，该方法包括：
步骤301：终端设备判断发送该与波束失败恢复相关的上行信号所在的第二小区与该第一小区是否为同一小区，当判定结果为“是”时，进入步骤302，当判定结果为“否”时，进入步骤303；
步骤302：该终端设备在接收到与波束失败恢复相关的下行信号的一段时间之后，并且在接收到或应用激活信令或重配置信令之前，使用和发送与波束失败恢复相关的上行信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号；
步骤303：该终端设备在接收到与波束失败恢复相关的下行信号的一段时间之后，并且在接收到或应用激活信令或重配置信令之前，使用和接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号。
在本实施例中，该第一小区可以是以下小区中的至少一个：
发送该与波束失败恢复相关的上行信号所在的小区；
发起该与波束失败恢复相关的上行信号的发送所对应的随机过程所在的小区；

接收该与波束失败恢复相关的下行信号所在的小区；
至少一个或所有的激活的小区；其中，激活的小区是指网络设备通过指示信令为终端设备激活的小区。
在该第一小区是发送该与波束失败恢复相关的上行信号所在的小区的情况下，该第一小区与第二小区是同一小区。
在本实施例中，该在第一小区上的上行信号例如是在物理上行链路控制信道(PUCCH)上发送的上行信号和/或在物理上行共享信道(PUSCH)上发送的上行信号。
例如，该在物理上行链路控制信道上发送的上行信号是用于承载第一控制信息所调度的下行信号的确认信息(例如，HARQ ACK/NACK信息)。其中，该第一控制信息所关联的搜索空间与该与波束失败恢复相关的下行信号所关联的搜索空间相同。例如，该搜索空间是由recoverySearchSpaceId提供的。
图4是本发明实施例1的发送和接收信号的一时序示意图。如图4所示，在发生波束失败之后，终端设备向网络设备发送与波束失败恢复相关的上行信号，例如波束恢复请求；终端设备在第一时刻接收到来自网络设备的与波束失败恢复相关的下行信号，例如波束失败恢复响应；在成功接收到该与波束失败恢复相关的下行信号的第一时刻的一段时间T1之后的第二时刻开始，直到该终端设备接收到或应用来自网络设备的激活信令或重配置信令的第三时刻结束的时间区间T2内，该终端设备使用和发送与波束失败恢复相关的上行信号或接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号(第四时刻)，该上行信号例如是在PUCCH或PUSCH上发生的上行信号。
由上述实施例可知，终端设备在接收到与波束失败恢复相关的下行信号的一段时间之后且在接收到或应用激活信令或重配置信令之前的时间区间内，使用和发送与波束失败恢复相关的上行信号或接收下行参考信号的空域传输滤波器相同的空域传输滤波器，发送在第一小区的上行信号。从而提供了一种终端设备在波束失败恢复成功之后使用空域传输滤波器发送上行信号的解决方案，提高了终端设备发送上行信号的可靠性。另外，该解决方案的适用性较广，其不仅适用于SpCell发生波束失败的场景，也适用于辅小区(SCell，Secondary Cell)发生波束失败的场景。另外，本解决方案还对所述一段时间的起始点做了精确的规定，避免了终端设备和网络设备对所述一段时间的起始点理解不一致而产生的不必要的收发错误。
实施例2
本发明实施例提供一种信号接收方法，该方法应用于网络设备侧，该方法对应于实施例1记载的信号发送方法。
图5是本发明实施例2的信号接收方法的一示意图。如图5所示，该方法包括：
步骤501：网络设备在发送了与波束失败恢复相关的下行信号的一段时间之后，并且在发送了激活信令或重配置信令或该激活信令或重配置信令生效之前，根据和接收与波束失败恢复相关的上行信号或发送下行参考信号相关的空间信息，接收在第一小区的上行信号。
这样，提供了一种网络设备在波束失败恢复成功之后根据空间信息接收上行信号的解决方案，提高了网络设备接收上行信号的可靠性。另外，该解决方案的适用性较广，其不仅适用于SpCell发生波束失败的场景，也适用于辅小区(SCell，Secondary Cell)发生波束失败的场景。在多载波(多服务小区被配置的)场景下，该解决方案可以正确的指示发送所述第一小区的上行信号所依据的空间信息，避免错误的指示其他的小区(非所述第一小区)的上行信号所根据的空间信息。
另外，本解决方案还对所述一段时间的起始点进行了精确的规定，避免了终端设备和网络设备对所述一段时间理解不一致而产生的不必要的收发错误。
在本实施例中，根据和接收与波束失败恢复相关的上行信号或发送下行参考信号相关的空间信息，接收在第一小区的上行信号，例如是，使用和接收与波束失败恢复相关的上行信号或发送下行参考信号的空域传输滤波器相同的空域传输滤波器，接收在第一小区的上行信号。
在步骤501中，网络设备在发送与波束失败恢复相关的下行信号的一段时间之后且在发送激活信令或重配置信令或所述激活信令或重配置信令生效之前的时间区间内，根据和接收与波束失败恢复相关的上行信号或发送下行参考信号相关的空间信息，接收在第一小区的上行信号。
也就是说，网络设备在发送与波束失败恢复相关的下行信号的一段时间之后，在需要接收在第一小区的上行信号的情况下，根据和接收与波束失败恢复相关的上行信号或发送下行参考信号相关的空间信息来接收该上行信号，直到该网络设备发送激活信令或重配置信令或该激活信令或重配置信令生效。
或者，也就是说，网络设备在发送与波束失败恢复相关的下行信号之后，如果发送所述与波束失败恢复相关的下行信号的时刻与所述网络设备接收所述上行信号的时刻的偏移(offset)大于或等于一段时间，则根据和接收与波束失败恢复相关的上行信号或发送下行参考信号的空域传输滤波器相关的空间信息，接收在第一小区的上行信号，直到网络设备发送激活信令或重配置信令或该激活信令或重配置信令生效。
在本实施例中，为了便于说明，将“发送与波束失败恢复相关的下行信号”的时刻称为第一时刻，将“发送与波束失败恢复相关的下行信号的一段时间”的时刻称为第二时刻，将“发送激活信令或重配置信令或该激活信令或重配置信令生效”的时刻称为第三时刻，将“接收在第一小区的上行信号”的时刻称为第四时刻。那么，在步骤501中，网络设备在所述第二时刻和所述第三时刻之间的时间区间内，使用上述空间信息，接收在第一小区的上行信号。或者，也可以理解为，网络设备在所述第一时刻与所述第四时刻的偏移(offset)大于或等于一段时间，且在第三时刻之前，根据上述空间信息，接收在第一小区的上行信号。在本实施例中，网络设备在发送激活信令或重配置信令或该激活信令或重配置信令生效之后，不再受到步骤501中的关于空间信息的使用限制。
在本实施例中，该与波束失败恢复相关的下行信号是网络设备向用户设备发送的与波束失败恢复相关的下行信号，例如，该与波束失败恢复相关的下行信号是波束失败恢复响应和/或波束失败恢复响应所调度的下行数据信息。
在本实施例中，该波束失败恢复响应可以是在由高层参数提供的搜索空间上发送的、由小区无线网络临时标识(C-RNTI，Cell Radio Network Temporary Identifier)或调制与编码策略小区无线网络临时标识(MCS-C-RNTI，Modulation and Coding  Scheme-Cell Radio Network Temporary Identifier)加扰的下行控制信息(DCI，Downlink Control Information)。
在本实施例中，该高层参数可以由无线资源控制(RRC，Radio Resource Control)信令配置。
在本实施例中，该高层参数可以用于配置发生波束失败恢复(BFR)随机接入响应(RAR，Random Access Response)的搜索空间集合(set)。
例如，该高层参数是恢复搜索空间集合标识(recoverySearchSpaceId)。
在本实施例中，该“一段时间”可以根据实际需要而设定。
例如，该一段时间可以是预设数量的符号(symbol)、时隙(slot)或毫秒(msec)。
例如，该一段时间是K个符号，或者，K个时隙，或者，K毫秒，其中，K是大于或等于0的整数。
在本实施例中，该一段时间的长度可以与子载波间隔(SCS，subcarrier spacing)相关。
例如，该一段时间的长度在不同的子载波间隔下，会发生变化。
例如，该一段时间的长度所对应的符号数可以正比于SCS，即，该SCS为15KHz时，该一段时间的长度为14个符号；该SCS为30KHz时，该一段时间的长度为28个符号；该SCS为60KHz时，该时间长度为56个符号，以此类推。
再例如，在该SCS为15kHz和30kHz时使用第一时间长度(例如14个符号)，在该SCS高于30kHz的情况下，使用第二时间长度(例如28个符号)。
在本实施例中，该一段时间的长度也可以与该终端设备的能力(UE capability)相关。具体的说，该终端设备的能力指的是上报给网络设备的终端设备的能力。
例如，该一段时间的长度在不同终端设备能力的等级下，会发生变化。
例如，在第一UE能力等级(或上报的第一UE能力等级的信息)的情况下，该一段时间的长度为第一时间长度(例如14个符号)；在第二UE能力等级(或上报的第二UE能力等级的信息)的情况下，该一段时间的长度为第二时间长度(例如28个符号)，以此类推。
在本实施例中，该一段时间的长度可以是被高层信令配置的。
在本实施例中，所述一段时间也可以理解为一个阈值，当所述第一时刻与所述第四时刻的偏移大于或等于所述阈值时，且在第三时刻之前，所述网络设备根据上述空 间信息，接收在第一小区的上行信号。

在本实施例中，该重配置信令可以是以下的至少一个：

与该网络设备所指示的终端设备天线面板相关的重配置信令；以及
目标小区是该第一小区的重配置信令。
例如，该RRC信令重配置了至少一个已配置的物理上行链路控制信道(PUCCH，Physical Uplink Control Channel)资源所关联的空间关系参数。
在本实施例中，该与波束失败恢复相关的上行信号可以是以下的至少一种信号：
波束失败恢复请求；
为了链路失败恢复的物理随机接入信道(PRACH)接收(reception)；以及
与所述与波束失败恢复相关的下行信号相关联的物理随机接入信道(PRACH)接收(reception)。具体的说，所述物理随机接入信道(PRACH)接收(reception)和所述与波束失败恢复相关的下行信号可以是时间的关联，例如，在时隙n进行所述物理随机接入信道(PRACH)接收(reception)，在时隙n+4发送相应的所述与波束失败恢复相关的下行信号(为了波束失败恢复的随机接入响应)。
在本实施例中，该与波束失败恢复相关的上行信号可以是由高层参数承载的。
在本实施例中，该高层参数可以由RRC信令承载。
更具体地说，

在本实施例中，该下行参考信号可以是该第一小区的下行参考信号。
在本实施例中，该下行参考信号的索引可以由MAC层的信令提供。例如，该下行参考信号的索引是由MAC层从高层参数中选出的。
例如，该下行参考信号的索引为q new，MAC层实体从RRC层参数中选出q new。例如，该RRC层参数为表示候选波束参考信号列表的参数candidateBeamRSList。
在步骤501中，当接收该与波束失败恢复相关的上行信号所在的第二小区与该第一小区是同一小区时，根据和接收与波束失败恢复相关的上行信号相关的空间信息，接收在第一小区的上行信号；当接收该与波束失败恢复相关的上行信号所在的第二小区与该第一小区不是同一小区时，根据和发送下行参考信号相关的空间信息，接收在第一小区的上行信号。
图6是本发明实施例2的信号接收方法的另一示意图。如图6所示，该方法包括：
