Description

信号收发方法、天线面板的指示方法、装置和系统 技术领域
本发明涉及通信领域，特别涉及一种信号收发方法、天线面板的指示方法、装置和系统。
背景技术
在高频通信场景中，提高通信传输的质量、吞吐量需要依靠波束成形技术。而波束成形技术的实现需要使用大规模天线阵列。在第五代移动通信技术的新无线(5G-NR)系统中，由于天线阵列所包含的天线粒子数量较多，在天线设计的时候，这些天线粒子通常分布在不同的天线面板上。对于终端设备而言，多个天线面板的方向通常是不同的。这样设计的好处是，当终端设备处于移动状态时，不同的天线面板能够在不同的方向上最大化接收和/或发送信号的增益，以便增强终端设备的接收和/或发送信号的鲁棒性。
在现有的技术中，5G-NR系统做到了对大规模天线阵列的波束指示。具体来说，波束所对应的信道状态是通过对参考信号的测量得到的；通过对参考信号的测量以及测量结果的上报，网络设备可以通过指示波束所对应的参考信号来决定接收和/或发送信号所使用的波束。
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，在5G-NR系统中，波束的测量上报以及后续的波束指示信息都没有包含与天线面板相关的信息。这意味着，对于网络设备而言，终端设备的天线面板信息是透明的。天线面板的开启和关闭只能由终端设备自行调整。但是，在网络设备的调度信令无法参考终端设备的天线面板的信息时，仅靠终端设备本身并不能最优化地使用天线面板。这样会导致开启不必要的天线面板，增加终端设备的能耗。

实施例1
本实施例提供了一种信号收发方法，该方法应用于终端设备。图2是本实施例的信号收发方法的示意图，请参照图2，该方法包括：
步骤201：终端设备接收网络设备发送的指示信息，所述指示信息指示了第一天线面板集合的相关信息；
步骤202：如果所述第一天线面板集合与所述终端设备激活的天线面板集合不同，则所述终端设备将激活的天线面板集合切换为所述第一天线面板集合；
步骤203：所述终端设备使用所述第一天线面板集合接收和/或发送信号。
在本实施例中，网络设备为终端设备指示了合适的天线面板集合(称为第一天线面板集合)，终端设备在其激活的天线面板集合与网络设备指示的该第一天线面板集合不同的情况下，将激活的天线面板集合切换为网络设备指示的该第一天线面板集合，由此，网络设备可以帮助终端设备在合适的时机开启或关闭天线面板，达到了节省能耗的目的。
在本实施例中，上述指示信息还可以对上述第一天线面板集合所适用的小区进行指示。例如，上述指示信息还可以指示第一小区，由此，终端设备将网络设备指示的该第一天线面板集合与其在第一小区的激活的天线面板集合进行比较，如果网络设备指示的第一天线面板集合与终端设备在该第一小区的激活的天线面板集合不同，则终端设备可以将该第一小区的激活的天线面板集合切换为网络设备指示的该第一天线面板集合，并在第一小区中使用该第一天线面板集合接收和/或发送信号。
在本实施例中，上述第一小区可以通过上述指示信息所关联的小区信息来指示。例如，如果该指示信息包含了小区信息(例如，小区ID)，则该第一小区为该小区信息所指示的小区，也即通过这种方式对第一小区进行了显式的指示。由此，能够指示不同的小区ID，扩大了指示的范围。再例如，如果该指示信息不包含小区信息(例如，小区ID)，则该第一小区为接收该指示信息所在的小区，也即通过这种方式对第一小区进行了隐式的指示。由此，不需要额外的开销来指示小区ID，节省了信令开销。
在本实施例中，上述天线面板集合可以是一个或多个天线面板构成的集合，其中，一个天线面板可以包括一个或多个天线粒子。在本实施例中，天线面板集合也可以理解为一个或多个天线面板的代号，或者，天线面板集合也可以理解为一个或多个天线 面板索引的集合。也就是说，天线面板集合指示了该集合所包含的一个或多个天线面板，而对于该天线面板的表现形式不作限制，可以是天线面板的代号，也可以是天线面板的索引，等等。
在本实施例中，第一天线面板集合与激活的天线面板集合不同，可以是指：该第一天线面板集合所对应的天线面板与该激活的天线面板集合所对应的天线面板不同，也可以是指：该第一天线面板集合的序号与该激活的天线面板集合的序号不同，还可以是指：该第一天线面板集合所对应的天线面板的序号与该激活的天线面板集合所对应的天线面板的序号不同。本实施例对此不作限制。
在本实施例的一个实施方式中，上述指示信息可以是下行控制信息(DCI)，上述第一天线面板集合的相关信息通过该DCI中的一个信息域承载。例如，该信息域的每个码点(codepoint)对应一个或多个天线面板集合。例如，该信息域具有两个比特，天线面板共有4个，编号分别为0,1,2,3，则码点与天线面板之间的关系可以是一对一映射：00→0；01→1；10→2；11→3，或者也可以是一对多(或一)映射：00→0,1；01→1；10→0,2,3；11→0,3。以上关系只是举例说明，还以通过其他方式通过该信息域的码点指示天线面板集合。
在本实施方式中，上述DCI的格式可以是0_1，也可以是1_1，关于该格式的说明，可以参考现有标准。
本实施方式使用DCI作为切换信令，时延较低，能够使得终端设备更及时地切换到合适的天线面板，从而减少功耗，增加传输成功率。
在本实施例的另一个实施方式中，上述指示信息可以是层2(layer 2)信令，上述第一天线面板集合的相关信息通过该层2信令中的一个域承载。
例如，层2信令可以是MAC CE(激活或指示)信令。对于该信令的一个承载域而言，该域的每个码点对应一个或多个天线面板集合。例如，该域具有两个比特，天线面板共有4个，编号分别为0,1,2,3，则码点与天线面板之间的关系可以是一对一映射：00→0；01→1；10→2；11→3，或者也可以是一对多(或一)映射：00→0,1；01→1；10→0,2,3；11→0,3。以上关系只是举例说明，还以通过其他方式通过该域的码点指示天线面板集合。
再例如，该域由多个比特构成，每个比特对应一个天线面板或者对应多个天线面板或者对应一个天线面板集合，每个比特通过比特值指示该比特对应的天线面板是否 开启。例如，该域由N个比特构成，N是正整数，N个比特同时只有一个可以为1，其余为0，由此指示“1”对应的天线面板或天线面板集合为开启状态；或者，N个比特同时只有一个可以为0，其余比特为1，由此指示“0”对应的天线面板或天线面板集合为开启状态；或者，N个比特中可以有多个为1，其余为0，由此指示“1”对应的天线面板或天线面板集合为开启状态；或者，N个比特中可以有多个为0，其余为1，由此指示“0”对应的天线面板或天线面板集合为开启状态。
本实施方式通过使用层2信令作为切换信令，可靠性高，且由于层2信令包括反馈机制，网络设备能够接收到天线面板是否成功切换的反馈，从而避免不必要的错误切换，增加了传输成功率，减少了功耗。
在本实施例的再一个实施方式中，上述指示信息可以是无线资源控制(RRC)信令，例如RRC配置信令，或者RRC重配置信令，上述第一天线面板集合的相关信息通过该RRC信令指示。在本实施方式中，上述RRC信令可以包含多个天线面板的索引或ID，或者包含一个天线面板集合的索引或ID，或者包含多个天线面板集合的索引或ID，以此指示上述第一天线面板集合。
本实施方式使用RRC信令作为切换信令，可靠性高，能够在发送配置信息的同时完成天线面板集合的切换，节省了信令资源。并且，由于RRC信令也包括反馈机制，网络设备能够接收到天线面板是否成功切换的反馈，从而避免不必要的错误切换，增加了传输成功率，减少了功耗。
通过本实施例的方法，终端设备可以根据网络设备的指示切换到更合适的天线面板(或天线面板集合)，由此增加了信号收发的成功率，减少了重传次数次数，并降低了能耗。

在本实施例的步骤601中，如果终端设备在第二小区被网络设备配置了与该第二小区相关的计时器，例如，终端设备接收网络设备发送的某个RRC配置信息(称为第一配置信息)，该第一配置信息指示了与第二小区相关的计时器。当该计时器超时，并且在该第二小区，终端设备激活的天线面板集合不是第三天线面板集合时，该终端设备在该第二小区将激活的天线面板集合切换为上述第三天线面板集合；或者，当上述计时器超时并且没有配置默认的天线面板集合，并且在该第二小区，终端设备激活的天线面板集合不是第三天线面板集合时，该终端设备在该第二小区将激活的天线面板集合切换为上述第三天线面板集合；或者，当上述计时器超时并且配置了默认的天线面板集合，并且在该第二小区，终端设备激活的天线面板集合不是上述默认的天线面板集合时，该终端设备在该第二小区将激活的天线面板集合切换为上述默认的天线面板集合。
