Description

通信方法及装置
本申请要求于2022年4月20日提交中国专利局、申请号为202210415195.0、申请名称为“通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
典型的多载波网络如图1A和图1B所示，多个载波可以部署在同一个基站上(共站部署，如图1A)，也可以部署在不同的基站上(异站部署，如图1B)。通常情况下，多载波网络中每个载波独立广播各自的同步信号块(synchronization signal block，SSB)和系统信息(system information，SI)，如图2所示，在图1A和图1B的场景下，在载波1所在的小区上广播载波1的SSB和SI，在载波2所在的小区上广播载波2的SSB和SI。
然而，如图3所示，在极简信号节能架构中一个载波也可以协助其他载波广播SI，具体如下：网络中的载波分为一个基础载波(basic component carrier，BCC)和若干个容量载波(capacity component carrier，CCC)。其中，BCC所在的小区为BCC小区，CCC所在的小区为CCC小区。BCC小区广播BCC小区的SSB和SI，并协助CCC小区广播CCC小区的SI(即BCC小区广播CCC小区的SI)。其中，CCC小区不广播CCC小区的SSB，而广播一个新的参考信号—探测参考信号(discovery reference signal，DRS)。DRS是对CCC小区的SSB的改进，具备CCC小区的SSB的基本功能，但是占用的正交频分复用(orthogonal frequency division multiplexing，OFDM)符号数更少，其中，CCC小区的SSB占用4个符号，DRS占用1～3个符号。CCC小区不广播CCC小区的SI，终端设备在BCC小区广播的SI中获取CCC小区的SI。CCC小区用于传输CCC小区的SI和SSB的符号数大幅减少，从而可以增加时域关断的机会，实现节省功耗的目的。
在该极简信号节能架构下，如图4所示，BCC小区可以协助CCC小区发送CCC小区的寻呼，即BCC小区发送CCC小区的寻呼，由于在物理下行共享信道(physical downlink shared channel，PDSCH)资源、寻呼阻塞率等不变的情况下，一个小区可承载的最大寻呼量是有限的，超出寻呼能力的寻呼会被丢弃，影响网络寻呼性能，因此当BCC小区寻呼压力过大时，需动态地将CCC小区的寻呼恢复到CCC小区上，以保证CCC小区的寻呼的性能。

其中，当该通信系统100包括一个网络设备，如图1A所示，该网络设备覆盖的小区包括小区1和小区2，小区1上发送的载波为载波1，载波1可以为BCC，小区2上发送的载波为载波2，载波2可以为CCC。当该通信系统100包括2个网络设备分别为网络设备1和网络设备2，如图1B所示，网络设备1覆盖的小区为小区1，网络设备2覆盖的小区为小区2，小区1上发送的载波为载波1，载波1可以为BCC，小区2上发送的载波为载波2，载波1可以为CCC。当该通信系统100包括3个网络设备分别为网络设备1、网络设备2和网络设备3，如图1C所示，网络设备1覆盖的小区为小区1，网络设备2覆盖的小区为小区2，网络设备3覆盖的小区为小区3，小区1上发送的载波可以为载波1，载波1可以为BCC，小区2上发送的载波可以为载波2，载波2可以为CCC1，小区3上发送的载波可以为载波3，载波3可以为CCC2。
在上述图1A、图1B和图1C场景下，小区1可以为BCC所在的小区，小区2为CCC1所在的小区，小区3可以为CCC2所在的小区，如图6所示，小区1上广播小区1的SSB和SI，并协助小区2和小区3广播小区2和小区3的SI(即小区1广播小区2和小区3的SI)。小区2上广播小区2的DRS，小区3上广播小区3的DRS，小区2的DRS是对小区2的SSB的改进，具备小区2的的SSB的基本功能，但是占用的正交频分复用(orthogonal frequency division multiplexing，OFDM)符号数更少，其中，小区2的SSB占用4个符号，小区2的DRS占用1～3个符号，小区3的DRS是对小区3的SSB的改进，具体可以参考小区2的DRS。小区2不广播小区2的SI，终端设备在小区1广播的SI中获取小区2的SI。小区3不广播小区3的SI，终端设备在小区1广播的SI中获取小区3的SI。在该方案中，小区2和小区3用于传输SI和SSB的符号数大幅减少，从而可以增加时域关断的机会，实现节省功耗的目的。其中，小区1由于广播数据量增加会导致功耗增加，但是小区1增加的功耗小于小区2节省的功耗，所以网络整体的功耗仍然可以降低。
在上述图1A、图1B和图1C场景下，小区1可以为BCC所在的小区，小区2为CCC1所在的小区，如图7A所示，小区1上广播小区1的寻呼，并协助小区2广播小区2的寻呼(即小区1广播小区2的寻呼)，此时小区2不广播小区2的寻呼，终端设备在小区1广播的寻呼中获取小区2的寻呼，通过这样的方式，能够实现降低小区2用于寻呼的符号数，增加时域关断机会，实现进一步的功耗降低。如图7B所示，当小区1上可承载的最大寻呼量过大时，需要动态的将小区2的寻呼恢复到小区2上，从而保证小区2的寻呼的性能，此时小区1上不广播小区2的寻呼，即小区2上广播小区2的寻呼，相应的，终端设备在小区2广播的寻呼中获取小区2的寻呼。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
一、寻呼：
在NR中，寻呼主要用于触发终端设备进行无线资源控制(radio resource control,RRC)的建立(RRC请求和RRC连接恢复)、系统信息修改通知和公共预警系统(public warning system，PWS)/地震和海啸预警系统(earthquake and tsunami warning system，ETWS)通知。当终端设备处于RRC空闲态(RRC_IDLE态)或者RRC非激活态(RRC_INACTIVE态)时，网络设备需要对其发起业务时，会对该用户发起寻呼，终端设备收到后发起RRC建立流程；当有系统消息更新时，网络设备可通过寻呼，指示终端设备在下个系统消息变更周期将要更新系统消息。
寻呼主要包括寻呼相关下行控制信息(downlink control information，DCI)和寻呼消息：其中寻呼相关DCI是由寻呼无线网络临时标识(paging radio network temporary identifier,P-RNTI)加扰一种DCI，该DCI格式为DCI Format1_0，且P-RNTI是对所有终端设备和小区共用的，其默认值为FFFE。寻呼相关DCI中可以指示寻呼消息在物理下行共享信道(physical downlink shared Channel，PDSCH)上发送的时频位置，因此终端设备可以根据寻呼相关DCI中的指示读取寻呼消息。寻呼消息中包含寻呼的终端设备的标识信息(UE ID)，当该寻呼为核心网寻呼时，UE ID为5G短临时移动用户标识(5G-short-temporary mobile subscriber identity，5G-S-TMSI)；当该寻呼为无线接入网(radio access network，RAN)寻呼时，UE ID为未活动无线网络临时标识(inactive radio network temporary identifier，I-RNTI)。当读取寻呼消息的终端设备发现寻呼的UE ID与自身匹配，则发起RRC建立流程。
寻呼相关DCI是在特定的时间发送的，即寻呼时机(paging occasion,PO)和寻呼帧(paging frame,PF)。其中，PO是一个物理下行控制信道(physical downlink control channel，PDCCH)监测时机的集合，由多个时隙组成，在该多个时隙中可以发送寻呼相关DCI。一个PF是一个包含一个或多个PO或PO的起点的无线帧。
小区所广播的系统信息中包括如下寻呼相关信息：默认寻呼周期(defaultPagingCycle)、寻呼帧数量(N)、寻呼帧偏移(PF_offset)以及寻呼时机数量(Ns)；其中，默认寻呼周期(defaultPagingCycle)用于指示监测寻呼帧的默认周期；寻呼帧数量(N)用于指示每个寻呼周期内的PF数量；寻呼帧偏移(PF_offset)用于指示PF的偏移帧数；寻呼时机数量(Ns)用于指示每个PF中包含的PO数量。终端设备需要检测的PO是根据终端设备的ID经过预定义的规则计算确定的。
例如，终端设备所检测的PO所在的PF的系统帧号(system frame number，SFN)，以及该SFN对应的PF内的PO的索引等，可以通过下面的公式确定：
PF的SFN满足：
在该SFN中的PO的索引is满足：
在如上公式中，SFN表示寻呼帧的系统帧号，PF_offset表示PF的偏移量，T表示终端设备被RRC或上层配置的非连续接收(discontinuous reception，DRX)周期，若终端设备未被被配置DRX周期，则T表示系统消息中的默认寻呼周期，N表示一个DRX周期内包括的PF的总数量，Ns表示一个PF中包含的PO数，mod表示取模运算，UE_ID表示根据终端设备的ID得到的量，floor(x)表示对x向下取整。其中，PFoffset、T、N、Ns等均是基站配置的，而 UE_ID则是根据终端设备的ID决定的。例如，UE_ID＝5G-S-TMSI mod 1024,其中，5G-S-TMSI为终端设备的5G短临时移动用户标识(5G-short-temporary mobile subscriber identity，5G-S-TMSI)，若终端设备未获得5G-S-TMSI，则UE_ID＝0。另外，由于NR系统往往具有基于SSB的波束扫描特征，因此一个PO中可以包括连续的s个PDCCH检测时机，其中s为基站在一个半帧中实际发送的SSB的数量。
目前，默认终端设备是在当前驻留/接入小区接收该小区的寻呼相关DCI以及寻呼消息。而在基于极简信号架构的寻呼位置动态变更方案中，寻呼DCI以及寻呼消息可以由驻留/接入小区发送，也可以由其他小区发送，且发送寻呼的小区会按需发生变更，如图7A和图7B所示。而目前不支持寻呼位置在驻留/接入小区以外的指示，同时缺少寻呼位置小区级变更时对终端设备的通知机制，因此为了解决上述问题，本申请实施例提出以下解决方案。
请参见图8，图8是本申请实施例提供的一种通信方法，该方法包括但不限于如下步骤：
步骤S801：网络设备向终端设备发送第一配置信息。
步骤S802：终端设备接收来自网络设备的第一配置信息。
具体地，该第一配置信息是通过第一小区发送的，该第一配置信息可以为第一寻呼的配置信息，该第一寻呼为第二小区的寻呼，例如，第二小区的寻呼可以是指用于触发终端设备进行与第二小区的RRC建立(RRC请求和RRC连接恢复)、第二小区的系统信息修改通知和PWS/ETWS通知。第一小区所属的网络设备和第二小区所述的网络设备可以为同一网络设备，也可以为不同的网络设备，例如，如图1A和图1B所示，第一小区可以为小区1，第二小区可以为小区2，其中，小区1发送的载波可以为BCC，小区2发送的载波为CCC。其中，第一小区可以为BCC所在的小区，第二小区可以为CCC所在的小区。第二小区可以是指多个小区，如图1C所示，第一小区可以为小区1，第二小区可以为小区2和小区3,其中，小区1发送的载波可以为BCC，小区2发送的载波可以为CCC1，小区3发送的载波可以为CCC2。
具体地，第一配置信息包括第一指示信息和第二指示信息，第一指示信息用于指示发送第一寻呼的小区。该第一指示信息可以为发送第一寻呼的小区的物理小区标识(physical cell identifier，PCI)或小区标识(cell identity)，或为发送第一寻呼的小区的指示，例如1表示发送第一寻呼的小区为第一小区，0表示发送第一寻呼的小区为第二小区。
具体地，第二指示信息用于指示在发送第一寻呼的小区上的第一寻呼的位置。例如，第一指示信息为1表示发送第一寻呼的小区为第一小区，那么第二指示信息用于指示在第一小区上第一寻呼的位置。该第二指示信息可以包括默认寻呼周期(defaultPagingCycle)，寻呼帧数量(N)，寻呼帧偏移(PF_offset)，寻呼时机数量(Ns)。
具体地，第一配置信息可以承载于第一小区所发送的系统信息中，该系统信息包括第一小区的系统信息和第二小区的系统信息，第二小区的系统信息还可以包括以下一项或多项：第二小区的标识信息，第二小区的频道编号，第二小区的接入信息，第二小区的其他配置信息。第二小区的标识信息可以为PCI或小区标识或第二小区的指示；第二小区的接入信息可以为用于小区选择的参考信号接收功率(reference signal receiving power，RSRP)和参考信号接收质量(reference signal receiving quality，RSRQ)相关参数，还可以为用于小区接入控制的禁止因子；第二小区的其他配置信息可以为PDCCH和PDSCH的时域和频域位置、或物理随机接入信道(physical random access channel，PRACH)的根序列索引。
步骤S803：终端设备在第一位置上接收DCI。
具体地，第一位置是根据第一配置信息确定的，具体如下，终端设备根据第一指示信息 确定发送第一寻呼的小区，然后根据该发送第一寻呼的小区和第二指示信息确定第一位置。也即终端设备根据第一指示信息确定发送第一寻呼的小区为第一小区或第二小区，当确定发送第一寻呼的小区为第一小区时，根据该第一小区和第二指示信息确定第一位置，该第一位置为第一小区上的第一寻呼的位置；当确定发送第一寻呼的小区为第二小区时，根据该第二小区和第二指示信息确定第一位置，该第一位置为第二小区上的第一寻呼的位置。可选的，终端设备可以在该第一位置进行监测。
其中，该第一位置包括PF位置和PO位置，该第一位置可以为在该发送第一寻呼的小区上的第一寻呼的PF位置和PO位置。例如，第一指示信息为1表示发送第一寻呼的小区为第一小区，终端设备根据第一指示信息确定发送第一寻呼的小区为第一小区，然后根据第二指示信息确定在第一小区上的第一寻呼的PF位置和PO位置，具体计算过程可以参考上述公式(1)和公式(2)。
具体地，该DCI是指第一寻呼的相关DCI，该DCI格式可以为DCI Format1_0。
可选的，当第一配置信息还包括：小区级P-RNTI；该小区级P-RNTI用于解扰在第一位置上接收到的DCI。也即终端设备可以根据第一配置信息确定小区级P-RNTI，进而根据该小区级P-RNTI解扰在第一位置上接收到的DCI。该小区级P-RNTI的值与默认的P-RNTI的值不同，例如，默认的P-RNTI的值为FFFE，该小区级P-RNTI的值可以为FFF0或者FFF1。该第一寻呼的小区级P-RNTI的值与可能在第一小区或第二小区上发送的其他寻呼的小区级P-RNTI的值不同，例如，发送第一寻呼的小区为第一小区，该第一寻呼的小区级P-RNTI的值为FFF0，在该第一小区上还发送第二寻呼，该第二寻呼为第三小区的寻呼，该第二寻呼的小区级P-RNTI的值为FFF8。
可选的，终端设备可以根据第二小区的标识信息确定小区级P-RNTI，该小区级P-RNTI用于解扰在第一位置上接收到的DCI。也即终端设备可以根据第二小区的标识信息确定小区级P-RNTI，进而根据该小区级P-RNTI解扰在第一位置上接收到的DCI。第二小区的标识信息可以为PCI或小区标识或第二小区的指示，例如，第二小区的标识信息为11，则小区级P-RNTI的值可以为FF11，例如，第二小区的标识信息为00，则小区级P-RNTI的值为FF00。
可选的，当终端设备确定发送第一寻呼的小区为第一小区，终端设备可以采用小区级P-RNTI解扰DCI；当终端设备确定发送第一寻呼的小区为第二小区，终端设备可以采用小区级P-RNTI或默认的P-RNTI解扰DCI，此处不做限定。具体可以如下，当发送第一寻呼的小区为第一小区，终端设备可以采用小区级P-RNTI解扰DCI，当发送第一寻呼的小区为第二小区，终端设备可以采用默认的P-RNTI解扰DCI。或，当发送第一寻呼的小区为第一小区或第二小区，终端设备可以采用小区级P-RNTI解扰DCI。
可选的，DCI包括第三指示信息，可选的，第三指示信息被包含于在第一位置上的DCI中或在第一位置上的DCI所指示的寻呼消息中，该第三指示信息用于指示发送第一寻呼的小区将发生变更。
在一种可能的实现方式中，该方法还包括：终端设备接收来自网络设备的第二配置信息，终端设备在第二位置上接收DCI。
具体地，第二配置信息为第一配置信息的重配置。该第二配置信息包括第四指示信息和第五指示信息，第四指示信息用于指示发送第一寻呼的变更后的小区；第五指示信息用于指示在发送第一寻呼的变更后的小区上的第一寻呼的位置。其中，第二位置是基于第二配置信息确定的，具体如下：终端设备根据第四指示信息确定发送第一寻呼的变更后的小区；并基于发送第一寻呼的变更后的小区和第五指示信息确定第二位置，具体计算过程可以参考上述 公式(1)和公式(2)。
可选的，第二配置信息还可以包括：变更后的小区级P-RNTI，即终端设备可以根据第二配置信息确定变更后的小区级P-RNTI。可选的，终端设备还可以根据变更后的小区的标识信息确定变更后的小区级P-RNTI，该变更后的小区级P-RNTI用于解扰在第二位置上接收到的DCI。具体可以参考上述所述。
在一种示例中，第一配置信息中的第一指示信息为1表示发送第一寻呼的小区为第一小区，第二指示信息用于指示在第一小区上第一寻呼的位置，终端设备接收到第三指示信息，该第三指示信息用于指示发送第一寻呼的小区将发生变更，终端设备接收通过第一小区发送的第二配置信息，该第二配置信息中的第四指示信息为0表示发送第一寻呼的小区为第二小区，第五指示信息用于指示在第二小区上第一寻呼的位置，也就是说，发送第一寻呼的小区由第一小区变更为第二小区。
在图8所描述的方法中，通过终端设备接收来自网络设备的第一配置信息，该第一配置信息包括第一指示信息和第二指示信息的方式，能够实现小区级的寻呼位置指示及变更，且可以使得终端设备在寻呼位置变更时获取变更通知，空口变化小；而且，通过引入小区级P-RNTI可以减少监测其他寻呼的终端设备进行非必要的系统信息更新，从而降低终端设备的能耗。
请参见图9，图9是本申请实施例提供的一种通信方法，该方法包括但不限于如下步骤：
步骤S901：网络设备向终端设备发送配置信息。
步骤S902：终端设备接收来自网络设备的配置信息。
具体地，该配置信息是通过第一小区发送的，该配置信息可以为第一寻呼的配置信息，该第一寻呼为第二小区的寻呼，例如，第二小区的寻呼可以是指用于触发终端设备进行与第二小区的RRC建立(RRC请求和RRC连接恢复)、第二小区的系统信息修改通知和PWS/ETWS通知。第一小区所属的网络设备和第二小区所述的网络设备可以为同一网络设备，也可以为不同的网络设备，具体可以参考步骤S802所述。
具体地，该配置信息包括第一指示信息和第二指示信息。该第一指示信息用于指示在第一小区上发送第一寻呼时的位置；第二指示信息用于指示在第二小区上发送第一寻呼时的位置。其中，第一指示信息和第二指示信息可以包括默认寻呼周期(defaultPagingCycle)，寻呼帧数量(N)，寻呼帧偏移(PF_offset)，寻呼时机数量(Ns)。
具体地，该配置信息可以承载于第一小区所发送的系统信息中，该系统信息包括第一小区的系统信息和第二小区的系统信息，第二小区的系统信息可以参考上述步骤S802所述。
具体地，该配置信息还可以包括第三指示信息，该第三指示信息用于指示发送第一寻呼的小区，该第三指示信息可以为发送第一寻呼的小区的PCI或小区标识或为发送第一寻呼的小区的指示，例如1表示发送第一寻呼的小区为第一小区，0表示发送第一寻呼的小区为第二小区。
步骤S903：终端设备在第一位置上接收DCI。
具体地，该DCI是指第一寻呼的相关DCI，该DCI格式可以为DCI Format1_0。
具体地，当配置信息包括第三指示信息，终端设备确定第一位置的方式如下：终端设备根据第三指示信息确定发送第一寻呼的小区，然后根据该发送第一寻呼的小区和配置信息确定第一位置。也即终端设备根据第三指示信息确定发送第一寻呼的小区为第一小区或第二小区，当确定发送第一寻呼的小区为第一小区时，根据该第一小区和配置信息中的第一指示信 息确定第一位置，该第一位置为在第一小区上发送第一寻呼时的位置；当确定发送第一寻呼的小区为第二小区时，根据该第二小区和配置信息中的第二指示信息确定第一位置，该第一位置为在第二小区上发送第一寻呼时的位置。其中，该第一位置可以包括PF位置和PO位置，该第一位置可以为在该发送第一寻呼的小区上的第一寻呼的PF位置和PO位置。
例如，第三指示信息为1表示发送第一寻呼的小区为第一小区，终端设备根据第三指示信息确定发送第一寻呼的小区为第一小区，然后根据第一小区和配置信息中的第一指示信息确定在第一小区上发送第一寻呼时的PF位置和PO位置，具体计算过程可以参考上述公式(1)和公式(2)。
在一种可能的实现方式中，该方法包括：终端设备接收第四指示信息，该第四指示信息用于指示发送第一寻呼的小区将发生变更。也即终端设备接收的第三指示信息指示发送第一寻呼的小区，当终端设备接收第四指示信息后，确定第三指示信息指示的发送第一寻呼的小区将发生变更。例如，第三指示信息为1表示发送第一寻呼的小区为第一小区，当终端设备接收第四指示信息，则表示发送第一寻呼的小区将变更为非第一小区，即将不在第一小区上发送第一寻呼。
其中，当该第四指示信息承载于第一寻呼的DCI中，和/或第一寻呼的寻呼消息中，该第四指示信息是通过发送第一寻呼的小区发送的。在一种示例中，当配置信息中的第三指示信息为1表示发送第一寻呼的小区为第一小区，终端设备接收第四指示信息，该第四指示信息承载于第一寻呼的DCI中，则该第四指示信息是通过第一小区发送的。

当发送第一寻呼的变更前的小区为第二小区，终端设备根据第四指示信息以及配置信息确定发送第一寻呼的变更后的小区为第一小区、以及在第一小区上的第一寻呼的位置，并在第一小区上的第一寻呼的位置上接收DCI。具体可以理解为：当发送第一寻呼的变更前的小区为第二小区，终端设备接收第四指示信息，该第四指示信息指示发送第一寻呼的小区将发生变更，则终端设备可以确定发送第一寻呼的小区将变更为非第二小区，即变更后的小区为第一小区，然后终端设备根据配置信息中的第一指示信息确定在第一小区上的第一寻呼的位置。可选的，终端设备在该在第一小区上的第一寻呼的位置进行监测，并接收DCI。
在一种可能的实现方式中，当该配置信息不包括第三指示信息，该方法还包括：终端设备根据配置信息确定在第一小区上的发送第一寻呼时的位置和在第二小区上发送第一寻呼时的位置，第一位置为在第一小区上的发送第一寻呼时的位置，或在第二小区上发送第一寻呼时的位置。也即可以理解为终端设备根据配置信息确定在第一小区上的发送第一寻呼时的位置和在第二小区上发送第一寻呼时的位置，可选的，终端设备可以在第一小区上的发送第一寻呼时的位置、和在第二小区上发送第一寻呼时的位置同时进行监测，然后在第一位置上接收DCI。通过这样的方式，终端设备可以获知在第一小区上的发送第一寻呼时的位置、以及在第二小区上的发送第一寻呼时的位置，并同时监测，能够在寻呼位置发生变更时终端设备免切换，从而避免因切换时延等原因导致的终端设备接收寻呼失败。
