Description

一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
长期演进(long term evolution，LTE)机器类型通信(machine type communication，MTC)系统或窄带物联网(narrow band internet of things，NB-IoT)系统有别于传统LTE通信，其不追求数据传输速率、多频段、多天线、全双工传输，而是要求终端设备能够实现低功耗(low power consumption)、低成本(low cost)。典型的MTC或NB-IoT的应用场景包括智能电网、智能农业、智能交通、智能家居以及环境检测等。在MTC或NB-IoT的应用场景中，其数据传输的特点是，数据量较小，且数据到达时间不确定。现有技术中，终端设备与基站之间为了传输数据，需要先通过随机接入(random access，RA)过程建立无线资源控制(radio resource control，RRC)连接，再通过建立的RRC连接传输数据。上述过程信令开销，以及时延较大，并且终端设备的功耗消耗较大。
为了节省信令开销、减少时延，以及终端设备的功耗，目前在随机接入过程的基础上，提出了数据早传(early data transmission，EDT)技术。在EDT过程中，终端设备可以通过消息3中的RRC消息向基站发送上行数据，或者基站可以通过消息4向终端设备发送下行数据。进一步的，为了更好的调度终端设备的下行数据，在随机接入过程或者EDT过程中，网络设备可能需要终端设备上报信道质量信息。然而，在随机接入过程或者EDT过程中，终端设备如何上报信道质量信息，是一个亟待解决的问题。
发明内容
本申请实施方式的目的在于提供一种通信方法及装置，用以解决终端设备如何上报信道质量信息的问题。
第一方面，本申请实施例提供一种通信方法，包括：终端设备生成第一MAC CE，所述第一MAC CE包括所述终端设备的信道质量信息；所述终端设备确定是否将所述第一MAC CE复用到消息3中；在所述终端设备确定将所述第一MAC CE复用到所述消息3中时，向网络设备发送包括所述第一MAC CE的所述消息3。
上述方法中，信道质量信息并不是通过消息3中的RRC消息发送的，而是通过消息3中的第一MAC CE发送的。若终端设备发起的是传统的随机接入过程或下行EDT过程，信道质量信息并不会占用RRC消息的资源，因此在消息3的资源足够大时，或者第一MAC CE的LCP优先级较高时，终端设备可以发送信道质量信息，从而提高信道质量信息发送成功的概率，进而提高信道质量信息的发送效率。若终端设备发起的是上行EDT过程，信道质量信息不会占用RRC消息中的上行数据的资源，因此在消息3的资源足够大时，或者第一MAC CE的LCP优先级较高时，终端设备可以发送信道质量信息，从而提高信道质量信息发送成功的概率，进而提高信道质量信息的发送效率。
一种可能的设计中，所述终端设备确定是否将所述第一MAC CE复用到所述消息3中，包括：所述终端设备根据所述第一MAC CE的逻辑信道优先级LCP优先级，确定是否将 所述第一MAC CE复用到所述消息3中。
上述方法中，终端设备在发送消息3时，根据第一MAC CE的LCP优先级，确定是否在消息3中复用第一MAC CE。当消息3的TBS较大，或者第一MAC CE的LCP优先级较高时，终端设备可以通过消息3发送第一MAC CE，从而提高信道质量信息发送成功的概率，进而提高信道质量信息的发送效率。
一种可能的设计中，所述第一MAC CE的逻辑信道优先级LCP优先级高于第二MAC CE的LCP优先级，所述第二MAC CE为包括填充BSR的MAC CE。
上述方法中，由于填充BSR是在消息3中存在空闲的比特时，利用空闲比特发送的，因此承载填充BSR的第二MAC CE的LCP优先级可以低于第一MAC CE的LCP优先级，从而提高信道质量信息发送成功的概率，进而提高信道质量信息的发送效率。。

具体的，本申请实施例中的终端设备，为向用户提供语音和/或数据连通性，具有无线收发功能的设备或可设置于该设备的芯片。该终端设备可以经无线接入网(radio access network，RAN)与一个或多个核心网通信。该终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、个人数字助理(personal digital assistant，PDA)虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。本申请中将前述终端设备及可设置于前述终端设备的芯片统称为终端设备。本申请实施例中的终端设备，也可以称为用户设备(user equipment，UE)、用户终端(user terminal)、接入终端(access terminal)、用户单元、用户 站、移动站(mobile station)、移动台(mobile)、远程站(remote station)、远程终端(remote terminal)、移动设备、无线通信设备、用户代理或用户装置。

本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例可以应用于NB-IoT以及增强型机器类通信(enhanced machine type of communication，eMTC)等网络，本申请实施例中部分场景以无线通信网络中NB-IoT网络的场景为例进行说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
本申请实施例可以应用于随机接入过程或者EDT过程，随机接入过程或者EDT过程可以如图2所示，主要包含4步消息流程：
步骤201：终端设备向网络设备发送随机接入前导(preamble)。
其中，所述随机接入前导也称为消息1(message 1，msg 1)，用于发起随机接入过程或者EDT过程。
需要说明的是，目前的NB-IoT系统中，会存在多个可以使用的前导码，这些前导码可以被划分为两个正交集合，一个集合中的前导码用于发起随机接入过程，以下简称集合1；另一个集合中的前导码用于发起EDT过程，以下简称集合2。如果终端设备发送的前导码来自集合1，则该前导码用于发起随机接入过程；如果终端设备发送的前导码来自集合2，则该前导码用于发起EDT过程。
需要说明的是，EDT过程还可以分为上行EDT过程和下行EDT过程。上行EDT过程是终端设备需要发送上行数据时，由终端设备主动发起的，其发送的前导码来自集合2。网络设备根据接收到的前导码，可以确定终端设备是否发起上行EDT过程。而下行EDT过程，是由网络设备发起的，例如在网络侧需要向终端设备发送下行数据时，网络设备可以指示终端设备发起下行EDT过程。
步骤202：所述网络设备向所述终端设备发送随机接入响应(random access response,RAR)。
RAR也可以称为消息2(message 2，msg 2)。
步骤203：所述终端设备向所述网络设备发送消息3(message 3，msg 3)。
在随机接入过程中，消息3不包括上行数据；在上行EDT过程中，消息3中包括终端 设备需要发送的上行数据。
需要说明的是，消息3是按照媒体接入控制(media access control，MAC)协议数据单元(protocol data unit，PDU)形式发送的。目前MAC PDU中包括M个MAC服务数据单元(service data unit，SDU)和N个MAC(control element，CE)，M、N为大于或等于0的整数。每个MAC SDU或者MAC CE对应一个逻辑信道优先级处理(Logical Channel Prioritization，LCP)优先级，每个MAC SDU或者MAC CE的LCP优先级是由网络设备配置的，或者协议预先约定的。
终端设备可能需要发送的上行数据是位于消息3中。由于终端设备需要优先发送RRC消息，因此承载RRC消息的MAC SDU的LCP优先级最高，终端设备优先将承载RRC消息的MAC SDU复用到消息3的MAC PDU中。
步骤204：所述网络设备向所述终端设备发送竞争解决消息。
该消息还可以称为消息4(message 4，msg 4)。在下行EDT过程中，消息4中还包括网络设备向终端设备发送的下行数据。
综上所述，随机接入过程与EDT过程之间，主要差别在消息3和消息4。在随机接入过程中，消息3不包括上行数据，消息4不包括下行数据；在上行EDT过程中，消息3中包括终端设备需要发送的上行数据。在下行EDT过程中，消息4中还包括网络设备向终端设备发送的下行数据
结合上述描述，如图3所示，为本申请实施例提供的一种通信方法的流程示意图。图3所示的流程可以应用于随机接入过程或者EDT过程中。
参见图3，该方法包括：
步骤301：终端设备生成第一MAC CE。
所述第一MAC CE包括所述终端设备的信道质量信息。
终端设备在生成第一MAC CE之前，还包括以下过程：终端设备向网络设备发送前导码，所述前导码用于发起随机接入过程或者EDT；所述终端设备接收所述网络设备发送的RAR，所述RAR为网络设备接收到所述前导码之后发送的。
步骤302：所述终端设备确定是否将所述第一MAC CE复用到消息3中；在所述终端设备确定将所述第一MAC CE复用到所述消息3中时，向网络设备发送包括所述第一MAC CE的所述消息3。
相应的，在终端设备确定不将所述第一MAC CE复用到所述消息3中时，向网络设备发送不包括所述第一MAC CE的所述消息3。
本申请实施例中，所述终端设备可以根据所述第一MAC CE的LCP优先级，确定是否将所述第一MAC CE复用到消息3中，也可以根据其他方式确定是否将所述第一MAC CE复用到消息3，在此不再赘述。
需要说明的是，所述第一MAC CE的LCP优先级为预先配置的，具体如何配置，本申请实施例对此并不限定。消息3中还包括承载RRC消息的MAC SDU，承载RRC消息的MAC SDU的LCP优先级最高，终端设备优先将承载RRC消息的MAC SDU复用到消息3的MAC PDU中。
其中，所述RRC消息可以为RRC数据早传请求(Early Data Request)消息，也可以为RRC连接恢复请求(Connection Resume Request)消息，还可以为RRC连接重建请求(Connection Reestablishment Request)消息，或者还可以为RRC连接请求(Connection  Request)消息等。
需要说明的是，步骤301或302之前，终端设备还可以在确定满足以下至少一项条件时，再执行步骤301或302：
所述终端设备接收到所述网络设备发送的第一指示信息，所述第一指示信息用于指示所述终端设备上报所述信道质量信息；
所述终端设备具有上报信道质量信息的能力。本申请实施例中，信道质量信息可以是信道质量指示(channel quality indicator，CQI)，也可以是终端设备传输数据的重复次数，还可以是终端设备确定出的参考信号接收功率(reference signal receiving power，RSRP)或参考信号接收质量(reference signal receiving quality，RSRQ)等，本申请实施例对此并不限定。
当满足上述至少一项条件时，终端设备确定需要通过随机接入过程或者EDT过程的消息3发送信道质量信息。
步骤303：网络设备接收终端设备发送的消息3。
所述消息3中包括第一MAC CE时，所述第一MAC CE为所述终端设备根据所述第一MAC CE的LCP优先级，将所述第一MAC CE复用到所述消息3中的。
步骤304：所述网络设备确定所述消息3中包括第一MAC CE时，根据所述第一MAC CE中的信道质量信息确定所述网络设备与所述终端设备之间的信道质量。
由于消息3中的RRC消息的资源有限，在随机接入过程或者EDT过程中，终端设备可能无法通过消息3中的RRC消息发送信道质量信息，即使终端设备通过消息3中的RRC消息发送信道质量信息，也可能会由于信道质量信息占用了上行数据的资源，导致终端设备只能传输部分上行数据，从而需要重新申请资源传输上行数据，导致上行数据时延较大。本申请实施例中，信道质量信息并不是通过消息3中的RRC消息发送的，而是通过消息3中的第一MAC CE发送的。若终端设备发起的是传统的随机接入过程或下行EDT过程，信道质量信息并不会占用RRC消息的资源，因此在消息3的资源足够大时，或者第一MAC CE的LCP优先级较高时，终端设备可以发送信道质量信息，从而提高信道质量信息发送成功的概率，进而提高信道质量信息的发送效率。若终端设备发起的是上行EDT过程，信道质量信息不会占用RRC消息中的上行数据的资源，因此在消息3的资源足够大时，或者第一MAC CE的LCP优先级较高时，终端设备可以发送信道质量信息，从而提高信道质量信息发送成功的概率，进而提高信道质量信息的发送效率。
结合前面的描述，本申请实施例中，终端设备在发送消息3之前，生成P个MAC SDU和Q个MAC CE，Q个MAC CE中包括第一MAC CE，P、Q为大于或等于0的整数。终端设备根据P个MAC SDU和Q个MAC CE的LCP优先级，将优先级高的MAC SDU和MAC CE复用并组装到消息3的MAC PDU中。终端设备可以根据所述第一MAC CE的LCP优先级，确定是否将所述第一MAC CE复用到消息3中。举例来说，终端设备在组装消息3的MAC PDU的过程中，可以确定P个MAC SDU和Q个MAC CE中，LCP优先级高于第一MAC CE的LCP优先级的所有MAC SDU和MAC CE所需的传输块大小(transport block size，TBS)，以下简称为第一TBS。终端设备若确定第一TBS大于或等于消息3的TBS，则可以确定不将所述第一MAC CE复用到消息3中；相应的，终端设备若确定第一TBS小于消息3的TBS，且消息3的TBS与第一TBS的差值大于或等于第一MAC CE所需的TBS，则可以确定将所述第一MAC CE复用到消息3中。
上述方法流程中，可以预先配置包括信道质量信息的第一MAC CE的LCP优先级，终端设备在发送消息3时，根据第一MAC CE的LCP优先级，确定是否在消息3中复用第一MAC CE。当消息3的TBS较大，或者第一MAC CE的LCP优先级较高时，终端设备可以通过消息3发送第一MAC CE，从而提高信道质量信息发送成功的概率，进而提高信道质量信息的发送效率。
本申请实施例中，第一MAC CE的LCP优先级可以为网络设备配置的，也可以为预设的，也可以为终端设备确定的。第一MAC CE的LCP优先级可以根据实际情况确定，例如所述第一MAC CE的LCP优先级可以高于第二MAC CE的LCP优先级，所述第二MAC CE为包括填充(padding)缓存状态报告(buffer status report，BSR)的MAC CE。
由于填充BSR是在消息3中存在空闲的比特时，利用空闲比特发送的，因此承载填充BSR的第二MAC CE的LCP优先级可以低于第一MAC CE的LCP优先级。
第一种可能的场景中，终端设备需要优先发送上行数据。举例来说，终端设备需要在上行EDT中发送消息3时，终端设备确定需要优先发送上行数据。当然，以上只是示例，终端设备也可以根据其他情况确定是否需要优先发送上行数据。
在该场景下，所述第一MAC CE的LCP优先级可以低于第一MAC SDU的LCP优先级，所述第一MAC SDU为包括逻辑信道的数据的MAC SDU。此时终端设备会优先把第一MAC SDU复用到消息3的MAC PDU中，从而可以提高上行数据的发送优先级。其中逻辑信道包括但不限于广播信道、公共控制信道和专用控制信道等，在此不再赘述。
上述方法中，在上行EDT过程中，由于第一MAC CE的LCP优先级低于第一MAC SDU的LCP优先级，在消息3的TBS较小时，可以优先保证上行数据的发送；在消息3的TBS较大时，可以保证上行数据全部发送的同时，通过消息3发送信道质量信息。
第二种可能的场景中，终端设备需要优先接收网络设备发送的下行数据。举例来说，终端设备需要在下行EDT中发送消息3时，终端设备确定需要优先接收网络设备发送的下行数据。当然，以上只是示例，终端设备也可以根据其他情况确定是否需要优先接收网络设备发送的下行数据。
在该场景下，所述第一MAC CE的LCP优先级可以高于第一MAC SDU的LCP优先级。此时终端设备会优先把第一MAC CE复用到消息3的MAC PDU中，从而可以提高信道质量信息的发送优先级。
上述方法中，在下行EDT过程中，由于第一MAC CE的LCP优先级高于第一MAC SDU的LCP优先级，可以优先发送信道质量信息，从而可以提高信道质量信息的发送的成功率。
上述第一至第二种可能的场景中，上报的信道质量信息由第一MAC CE承载，无需RRC层参与，终端设备的MAC层根据消息3的MAC PDU的TBS就可以判断是否在消息3中发送包括信道质量信息的第一MAC CE。
本申请实施例中，由于第一MAC CE的LCP优先级可以配置为低于任意逻辑信道的数据的LCP优先级，当终端设备有数据需要发送，但是MAC PDU的TBS不足以同时发送数据和第一MAC CE时，终端设备会优先发送数据，保证数据的发送不会受到上报信道质量信息的影响。
另外，由于第一MAC CE的LCP优先级可以配置为高于任意逻辑信道的数据的LCP优先级，当终端设备有数据需要发送，但是MAC PDU的TBS不足以同时发送数据和该信 道质量信息MAC CE时，终端设备会优先上报信道质量信息，终端设备的数据可以在后续传输中进行发送。
本申请实施例中，当前进行的是随机接入过程时，网络设备为消息3分配的TBS会大于或等于56比特，只能保证可以发送不包含该信道质量信息的RRC消息(该RRC消息为RRC连接重建请求(Connection Reestablishment Request)消息，或者RRC连接请求(Connection Request)消息等)，如果在RRC消息中包含该信道质量信息，有可能导致RRC消息需要的比特数大于网络设备分配的消息3的TBS，导致该RRC消息无法发送。为此，本申请实施例中，终端设备在发送消息3之前，可以预先进行判断是否可以通过消息3发送信道质量信息，提高信道质量信息的发送成功的概率，下面将详细描述。
结合上述描述，如图4所示，为本申请实施例提供的一种通信方法的流程示意图。图4所示的流程可以应用于随机接入过程或者EDT过程中。
参见图4，该方法包括：
步骤401：终端设备确定是否通过消息3发送信道质量信息。
步骤402：若终端设备确定通过消息3发送信道质量信息，则生成包括所述信道质量信息的RRC消息，并向网络设备发送包括所述RRC消息的所述消息3。
其中，所述RRC消息可以为RRC数据早传请求(Early Data Request)消息或RRC连接恢复请求(Connection Resume Request)消息，或者RRC连接重建请求(Connection Reestablishment Request)消息，或者RRC连接请求(Connection Request)消息。
步骤403：网络设备接收终端设备发送的消息3。
步骤404：所述网络设备确定所述消息3中的RRC消息包括信道质量信息时，根据所述信道质量信息确定所述网络设备与所述终端设备之间的信道质量。
上述方法流程中，由于当网络设备指示允许终端设备上报信道质量信息时，网络设备通常会为消息3分配足够的TBS，此时终端设备可以通过消息3发送信道质量信息。但是目前只有部分终端设备支持在消息3中上报信道质量信息，如果网络设备为所有终端设备的消息3都分配足够的TBS，对于不支持上报信道质量信息的终端设备，会导致资源浪费。因此，网络设备为消息3分配的TBS可能不足以终端设备发送信道质量信息。为此，终端设备在发送消息3之前，需要确定是否通过消息3发送信道质量信息，只有确定可以通过消息3发送信道质量信息时，才通过消息3发送包括所述信道质量信息的RRC消息，从而在保证上行数据传输的同时，提高资源利用率。
需要说明的是，步骤401或402之前，所述终端设备可以判断是否满足以下至少一项条件：
所述终端设备接收到所述网络设备发送的第一指示信息，所述第一指示信息用于指示所述终端设备上报所述信道质量信息；
所述终端设备具有上报信道质量信息的能力。
当满足上述至少一项条件时，终端设备可以向网络设备发送前导码，所述前导码用于发起随机接入过程或者EDT；所述终端设备接收所述网络设备发送的RAR。
终端设备在发送消息3之前，可以通过多种方式确定是否通过消息3发送信道质量信息，下面将详细描述。
第一种可能的实现方式中，所述终端设备可以根据消息3的TBS确定是否通过消息3发送信道质量信息。
具体的，终端设备若确定所述消息3的TBS大于或等于第一阈值时，则确定可以通过所述消息3发送所述信道质量信息。相应的，终端设备若确定所述消息3的TBS小于第一阈值时，则确定不可以通过所述消息3发送所述信道质量信息。
通过上述方法，终端设备发起不论是传统的随机接入过程，还是下行EDT过程或上行EDT过程，终端设备只有确定消息3的TBS大于或等于第一阈值时，确定消息3的资源足够大，才通过消息3发送信道质量信息，从而提高信道质量信息发送成功的概率，进而提高信道质量信息的发送效率。
本申请实施例中，第一阈值可以通过多种方式确定。举例来说，第一阈值可以为网络设备发送的，或者网络设备与终端设备预先约定的。例如，网络设备可以向终端设备发送第一阈值，第一阈值可以为64比特或8字节等。当消息3的TBS大于或等于第一阈值时，终端设备确定在所述RRC消息中包含所述信道质量信息；否则，终端设备确定在所述RRC消息中不包含所述信道质量信息。
第一阈值还可以为承载在所述消息3中的上行数据所需的TBS和包括所述信道质量信息的所述RRC消息所需的TBS之和。当终端设备确定所述消息3的TBS大于或等于第一阈值时，也就是当所述消息3的TBS可以同时容纳上行数据和包括所述信道质量信息的所述RRC消息时，可以认为消息3的TBS足够大，能够携带信道质量信息；相应的，当终端设备确定所述消息3的TBS小于第一阈值时，可以认为消息3的TBS较小，不能够携带信道质量信息。
上述过程中，终端设备根据消息3的TBS判断是否在RRC消息中发送信道质量信息时，当消息3的TBS不足够时，终端设备可以优先通过消息3发送数据，信道质量信息作为辅助信息，可以暂时不发送。相应的，当消息3的TBS足够时，终端设备可以通过消息3发送信道质量信息。
需要说明的是，本申请实施例中，消息3的MAC PDU属于MAC层，因此终端设备的MAC层实体可以确定消息3的TBS，进而终端设备的MAC层实体可以向上层指示消息3的TBS。所述上层可以为RRC层。
进一步的，本申请实施例中，可以由终端设备的MAC层实体根据消息3的TBS判断是否通过消息3发送信道质量信息。例如，当消息3的TBS大于或等于第一阈值时，终端设备的MAC层实体确定在所述RRC消息中包含所述信道质量信息，并向终端设备的RRC层实体发送传输指示信息，上述传输指示信息用于指示消息3的TBS大于或等于第一阈值，终端设备的RRC层实体从而可以确定需要在RRC消息中包含所述信道质量信息。
当然，本申请实施例中，终端设备的MAC层实体也可以确定是否在消息3的RRC消息中包含信道质量信息，并指示给RRC层实体。例如，当消息3的TBS大于或等于第一阈值时，终端设备的MAC层实体可以直接向终端设备的RRC层实体指示在RRC消息中包含所述信道质量信息。再例如，终端设备的MAC层实体根据消息3的TBS和上行数据所需的TBS等信息，判断消息3没有足够的资源发送信道质量信息，从而指示RRC层实体是否在消息3的RRC消息中包含所述信道质量信息。
第二种可能的实现方式中，当终端设备确定消息3为EDT过程中的消息，则可以确定终端设备正在进行上行EDT过程或者正在进行下行EDT过程。终端设备可以认为消息3的TBS足够大，从而可以通过消息3的RRC消息发送信道质量信息。或者终端设备确定消息3中的RRC消息为RRC数据早传请求(Early Data Request)消息或RRC连接恢复 请求(Connection Resume Request)消息时，终端设备可以认为消息3的TBS足够大，从而可以通过消息3的RRC消息发送信道质量信息。相应的，当终端设备确定消息3为随机接入过程中的消息，则可以确定网络设备为消息3分配的TBS较小，从而确定不可以通过消息3的RRC消息发送信道质量信息。
上述过程中，终端设备通过判断消息3的类型，确定是否为上行EDT过程或者下行EDT过程。由于上行EDT过程或者下行EDT过程中的消息3的TBS通常足够大，在大多数情况下，可以保证同时发送信道质量信息和终端设备的数据。
