Description

信号传输方法和装置
本申请要求于2016年09月28日提交中国专利局、申请号为201610858515.4、申请名称为“信号传输方法和装置”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
本申请实施例涉及通信领域，并且更具体地，涉及一种信号传输方法和装置。
背景技术
在无线通信系统中，为了在保证传输可靠性的前提下提升传输效率，网络设备通常会估计用于传输信号的无线信道的质量，并根据无线信道的质量确定调度方案。在目前的无线通信系统中，通常会借助传输参考信号来获取无线信道的质量信息。通信系统通常使用不同种类的参考信号：一类参考信号用于信道质量测量，如小区特定参考信号(cell-specific reference signal，CRS)，从而可以实现信道质量测量和小区选择、切换；另一类参考信号用于信道状态信息的测量，从而实现对终端设备的调度。例如，终端设备基于对信道状态信息参考信号(channel state information reference signal，CSI-RS)的信道质量测量，就可以得到对应的信道状态信息CSI。
在现有技术中，为了测量信道质量，网络设备可以向终端设备发送多个参考信号，并向该终端设备配置需要上报的信道质量信息的数目N，该终端设备接收该网络设备发送的多个参考信号，基于该网络设备的配置，对该网络设备发送的所有参考信号进行扫描和测量，获得最优的N个信道质量信息，并将该最优的N个信道质量信息上报给该网络设备。
但是，当该网络设备发送的多个参考信号对应的信道质量信息均较差，且该网络设备配置的需要该终端设备上报的信道质量信息的数目N较大时，该终端设备将N个都很差的信道质量信息全部上报给该网络设备的必要性不大，且这样也会导致不必要的信令开销。
发明内容
有鉴于此，本申请实施例提供一种信号传输方法和装置，能够避免终端设备上报不必要的信道质量信息，节省该终端设备的信令开销以及能耗。
第一方面，提供了一种信号传输方法，包括：网络设备向终端设备发送信道质量门限值，所述信道质量门限值用于所述终端设备进行第一信道质量信息的上报，所述信道质量门限值为第二信道质量信息的门限值；所述网络设备接收所述终端设备根据所述信道质量门限值发送的第一数目的所述第一信道质量信息。
应理解，第一信道质量信息为上报量，而第二信道质量信息为触发量。对于具体某个参考信号而言，一旦该参考信号对应的第二信道质量信息超出该信道质量门限值，那么该 终端设备可以确定需要上报该参考信号对应的第一信道质量信息。该第一信道质量信息与该第二信道质量信息可以相同，也可以不同，本申请实施例对此不作限定。
本申请实施例的信号传输方法，通过网络设备向终端设备发送信道质量门限值，触发该终端设备上报满足条件的参考信号对应的信道质量信息，能够避免该终端设备进行不必要的信道质量信息的上报，节省该终端设备的信令开销以及能耗，从而提高用户体验。
可选地，上述终端设备向该网络设备发送第一数目的该第一信道质量信息，可以采用多种上报方式。该终端设备可以在确定满足信道质量门限值的第一数目的参考信号的第二信道质量信息时，将该第一数目的参考信号对应的第一信道质量信息一起发送给该网络设备，即采用批量上报的方式，也可以依次分别将该第一信道质量信息发送给该网络设备，即采用单独上报的方式，本申请实施例对此不作限定。
对于单独上报的方式，若该网络设备确定该终端设备上报的第一信道质量信息的数目已经达到了要求，可以通知该终端设备停止进行参考信号的发送及基于所述参考信号的信道质量的检测，该网络设备也可以停止发送参考信号，从而节省网络设备与终端设备双侧的信号发送开销以及处理的复杂度。
由于终端设备向网络设备上报信道质量信息前需要该网络设备为该终端设备预留时频资源，因此，相比随机的单独上报方式，采用批量上报的方式能够极大节省待预留资源的数目，从而大大提高资源利用率。
可选的，该终端设备可以根据该网络设备发送的信道质量门限值来确定上述上报方式。若该信道质量门限值较小，该终端设备可以采用批量上报的方式，若该信道质量门限值较大，该终端设备可以采用单独上报的方式，本申请实施例对此不作限定。
在第一方面的第一种可能的实现方式中，在所述网络设备接收所述终端设备根据所述信道质量门限值发送的第一数目的所述第一信道质量信息之前，所述方法还包括：所述网络设备向所述终端设备发送第二数目，所述第二数目用于表示所述网络设备为所述终端设备配置的所述第一信道质量信息的数目；所述网络设备接收所述终端设备根据所述信道质量门限值发送的第一数目的所述第一信道质量信息，包括：所述网络设备接收所述终端设备根据所述信道质量门限值以及所述第二数目，发送的所述第一数目的所述第一信道质量信息，所述第一数目小于或者等于所述第二数目。
应理解，该第二数目即为该网络设备请求该终端设备上报的第一信道质量信息的数目。该终端设备可以接收该网络设备发送的该第二数目，然后根据所述信道质量门限值和/或所述第二数目确定并发送第一数目的第一信道质量信息，因此，该第一数目可以小于或者等于该第二数目。
可选的，该第二数目取值可以为1、2、4中的任意一个。
因此，通过本申请实施例的信号传输方法，能够避免该终端设备进行不必要的信道质量信息的上报，节省该终端设备的信令开销。
结合第一方面的上述可能的实现方式，在第一方面的第二种可能的实现方式中，所述网络设备向所述终端设备发送第二数目，包括：所述网络设备向所述终端设备发送第一信令，所述第一信令携带所述第二数目，且所述第一信令为高层信令或物理层信令。
结合第一方面的上述可能的实现方式，在第一方面的第三种可能的实现方式中，所述网络设备向终端设备发送信道质量门限值，包括：所述网络设备向所述终端设备发送第二 信令，所述第二信令携带所述信道质量门限值，且所述第二信令为高层信令和/或物理层信令。
应理解，该高层信令可以为无线资源控制(radio resource control，RRC)信令，该物理层信令可以为下行控制信息(downlink control information，DCI)信令，该高层信令以及该物理层信令还可以为其他信令，本申请实施例对此不作限定。此外，该网络设备发送该第二数目以及该信道质量门限值还可以采用其他信令的任意组合，本申请实施例对此也不作限定。
结合第一方面的上述可能的实现方式，在第一方面的第四种可能的实现方式中，所述网络设备接收所述终端设备根据所述信道质量门限值发送的第一数目的所述第一信道质量信息，包括：所述网络设备接收所述终端设备根据所述信道质量门限值发送的所述第一数目以及所述第一数目的所述第一信道质量信息。
本实施例中，终端设备可以根据实际情况进行上报，该网络设备可以根据该终端设备发送的第一数目确定该终端设备上报的第一信道质量信息的个数，进行解码，从而节省了该终端设备的上报开销。
结合第一方面的上述可能的实现方式，在第一方面的第五种可能的实现方式中，在所述网络设备接收所述终端设备根据所述信道质量门限值发送的第一数目的所述第一信道质量信息之前，所述方法还包括：所述网络设备向所述终端设备发送第一通知消息，所述第一通知消息用于通知所述网络设备到所述终端设备的参考信号的发送。
具体的，该网络设备在向该终端设备发送参考信号之前，可以先向该终端设备发送第一通知消息，用于通知该终端设备该网络设备将在接下来连续的P(P为大于或等于1的整数)个参考信号发送时刻向该终端设备发送参考信号，以便于该终端设备能够做好准备，及时接收该网络设备发送的参考信号，并对该参考信号对应的信道质量进行测量。
结合第一方面的上述可能的实现方式，在第一方面的第六种可能的实现方式中，所述方法还包括：所述网络设备向所述终端设备发送第二通知消息，所述第二通知消息用于通知所述网络设备到所述终端设备的参考信号的发送终止。
具体的，该网络设备可以向该终端设备发送第二通知消息，用于通知该终端设备该网络设备停止发送参考信号。应理解，对于该终端设备分别上报满足所述信道质量门限值的每个参考信号的第一信道质量信息的情况，若该网络设备已经确定了满足所述信道质量门限值的第一数目的信道质量信息，便可以向该终端设备发送第二通知消息，该终端设备接收到该第二通知消息之后，便不会再进行参考信号的接收及对应的参考信号的信道质量的测量，也不会再向该网络设备上报第一信道质量信息。这样，一定程度上降低了终端设备的上报开销，减小了该终端设备的处理复杂度。
结合第一方面的上述可能的实现方式，在第一方面的第七种可能的实现方式中，所述第一信道质量信息为下列信息中的至少一种：参考信号索引、与所述参考信号索引对应的参考信号接收功率RSRP、与所述参考信号索引对应的参考信号接收质量RSRQ以及与所述参考信号索引对应的信道质量指示CQI，其中，所述参考信号索引用于表示与所述第一信道质量信息对应的参考信号。
应理解，该第一信道质量信息可以为LTE中的CSI信息，例如信道状态信息参考信号指示符(CSI-RS index，CRI)、秩指示(rank indication，RI)、预编码矩阵指示(precoding  matrix indicator，PMI)、信道质量指示(channel quality indication，CQI)等等中的至少一个，或者该第一信道质量信息还可以为无线资源管理(radio resource management，RRM)测量的信道质量信息，例如RSRP、RSRQ等中的至少一个。此外，该第一信道质量信息还可以为上述信息外的其他任意一种或多种信道质量信息，或者除上述信息之外还包括其他任意一种或多种信道质量信息，本申请实施例对此不作限定。
结合第一方面的上述可能的实现方式，在第一方面的第八种可能的实现方式中，所述第二信道质量信息为参考信号接收功率RSRP、参考信号接收质量RSRQ或信道质量指示CQI。
应理解，该第二信道质量信息可以为上述CRI、RI、PMI、CQI、RSRP、RSRQ中的任意一种，或者为其他任意一种信道质量信息，本申请实施例对此不作限定。

本申请实施例的信号传输方法，通过终端设备接收网络设备发送的信道质量门限值，触发该终端设备上报满足条件的参考信号对应的信道质量信息，能够避免该终端设备进行不必要的信道质量信息的上报，节省该终端设备的信令开销以及能耗，从而提高用户体验。

应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、以及未来的5G通信系统等。
图1示出了本申请实施例应用的通信系统100。该通信系统100可以包括至少一个网络设备110。网络设备100可以是与终端设备通信的设备，如基站或基站控制器等。每个网络设备100可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端设备(例如UE)进行通信。该网络设备100可以是GSM系统或码分多址(code division multiple access，CDMA)系统中的基站(base transceiver station，BTS)，也可以是WCDMA系统中的基站(nodeB，NB)，还可以是LTE系统中的演进型基站(evolutional node B，eNB或eNodeB)，或者是云无线接入网络(cloud radio access network，CRAN)中的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、未来5G网络中的网络侧设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的多个终端设备120。该终端设备120可以是移动的或固定的。该终端设备120可以指接入终端、用户设备(user equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的 手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的终端设备等。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例不限于此。
在现有技术中，为了测量信道质量，网络设备可以向终端设备发送多个参考信号，并向该终端设备配置需要上报的信道质量信息的数目N，该终端设备接收该网络设备发送的多个参考信号，基于该网络设备的配置，对该网络设备发送的所有参考信号进行扫描和测量，获得最优的N个信道质量信息，并将该最优的N个信道质量信息上报给该网络设备。
随着通信技术的发展，对于参考信号的接收和发送将可以采用基于波束赋形技术的信号传输机制，以通过较大的天线增益来补偿信号传播过程中的损耗，从而保证上行覆盖性能、小区平均吞吐量和边缘用户速率等参数的显著提高。其中，该波束赋形技术为模拟域的波束赋形，基带域的波束赋形以及混合波束赋形中的任意一种，且该波束赋形的信号可以为小区特定的第一类参考信号，也可以为用户特定的第二类参考信号等，还可以为其他参考信号。
具体的，基于波束赋形的信号传输的波束管理机制包括三个主要过程：
(1)最优的一个或多个收发波束对的选择，用于终端设备基于网络设备侧的不同波束扫描实现对最优发射波束和/或接收波束的选择；
(2)发射波束的更新，用于终端设备基于网络设备侧的不同发射波束的扫描实现对发射波束的更新；
(3)接收波束的更新，用于终端设备基于网络设备侧的多次重复相同的发射波束扫描实现对接收波束的更新；
终端设备通过上述波束管理机制可实现对收发波束的追踪和更新。
在基于波束赋形的信号传输机制下，可选地，参考信号与波束一一对应，参考信号对应的信道质量信息也与波束一一对应。为了测量基于多个参考信号的信道质量以进行波束的跟踪和更新，该网络设备可以直接向终端设备配置与参考信号对应的待选择的最优波束的数目N，该终端设备基于该波束数目N进行相应的信道质量信息的上报，在这种情况下，待选择的最优波束数目N即为与所述波束对应的信道质量信息的个数N。可选地，所述数目N也为待选择的最优波束对应的参考信号个数。
但是，当该网络设备发送的多个参考信号对应的信道质量信息均较差，且该网络设备配置的需要该终端设备上报的信道质量信息的数目N较大时，该终端设备将N个信道质量信息全部上报给该网络设备的必要性不大，且这样会导致不必要的信令开销。
图2示出了本申请实施例提供的信号传输方法200的示意性流程图。该方法200可以应用于图1所示的系统架构100，但本申请实施例不限于此。
S210，网络设备向终端设备发送信道质量门限值，所述信道质量门限值用于所述终端设备进行第一信道质量信息的上报，所述信道质量门限值为第二信道质量信息的门限值；
S220，该终端设备接收网络设备发送的信道质量门限值，并根据该信道质量门限值，确定第一数目的所述第一信道质量信息；
S230，该终端设备向所述网络设备发送所述第一数目的所述第一信道质量信息。
具体的，该网络设备可以向该终端设备发送信道质量门限值，该信道质量门限值用于触发该终端设备上报第一信道质量信息，且该信道质量门限值为第二信道质量信息的门限值。即第一信道质量信息为上报量，而第二信道质量信息为触发量。对于具体某个参考信号而言，一旦该参考信号对应的第二信道质量信息超出该信道质量门限值，那么该终端设备可以确定需要上报该参考信号对应的第一信道质量信息。应理解，该第一信道质量信息与该第二信道质量信息可以相同，也可以不同，本申请实施例对此不作限定。
该终端设备接收该网络设备发送的信道质量门限值，然后将该信道质量门限值与接收到的多个参考信号中每个参考信号的第二信道质量信息进行比较，若存在某个参考信号的第二信道质量信息大于该信道质量门限值，则该终端设备确定要上报该参考信号对应的第一信道质量信息。该终端设备可以确定第一数目的该第一信道质量信息，然后将该第一数目的该第一信道质量信息发送给该网络设备，这里，该第一数目为大于或等于1的整数。
因此，本申请实施例的信号传输方法，通过网络设备向终端设备发送信道质量门限值，触发该终端设备上报满足门限值条件的参考信号对应的信道质量信息，能够避免该终端设备进行不必要的信道质量信息的上报，节省该终端设备上报的信令开销以及能耗，从而提高用户体验。
应理解，上述终端设备向该网络设备发送第一数目的该第一信道质量信息，可以采用多种上报方式。该终端设备可以在确定满足信道质量门限值的第一数目的参考信号的第二信道质量信息时，将该第一数目的参考信号对应的第一信道质量信息一起发送给该网络设备，即采用批量上报的方式，也可以依次分别将该第一信道质量信息发送给该网络设备，即采用单独上报的方式，本申请实施例对此不作限定。
具体的，对于单独上报的方式，例如，若网络设备采用时分的方式向终端设备发送参考信号，该终端设备在接收到第一个参考信号时，就可以检测该第一个参考信号对应的信道质量，从而确定第一信道质量信息以及第二信道质量信息，若该第二信道质量信息超出上述信道质量门限值，该终端设备可以立即向该网络设备上报该第一个参考信号的第一信道质量信息，无需等待基于后续参考信号的信道质量测量全部完成。该终端设备在检测到后续其他满足条件的参考信号后，再依次向该网络设备发送后续其他参考信号对应的第一信道质量信息。该网络设备接收该终端设备发送的第一数目的第一信道质量信息，便可以根据该第一信道质量信息，确定出第一数目的参考信号对应的信道质量信息，从而进行后续的数据传输。若该网络设备确定该终端设备上报的第一信道质量信息的数目已经达到了要求，可以通知该终端设备停止进行参考信号的发送及基于所述参考信号的信道质量的检测，该网络设备也可以停止发送参考信号，从而节省网络设备与终端设备双侧的信号发送开销以及处理的复杂度。
而对于批量上报的方式，该终端设备可以确定出多个满足条件的参考信号的第一信道质量信息，然后一起发送给该网络设备。由于终端设备向网络设备上报信道质量信息前需要该网络设备为该终端设备预留时频资源，因此，采用批量上报的方式能够减少终端设备所需预留的时频资源，从而大大提高资源利用率。
可选的，该终端设备可以根据该网络设备发送的信道质量门限值来确定上述上报方式。若该信道质量门限值较小，该终端设备可以采用批量上报的方式，若该信道质量门限值较大，该终端设备可以采用单独上报的方式，例如，若第二信道质量信息为参考信号接收功率RSRP，对应的信道质量门限值为-100db时，该终端设备可以确定采用批量上报，对应的信道质量门限值为-70db时，该终端设备可以确定采用单独上报。对此，本申请实施例不作限定。
应理解，上述信道质量门限值与上报方式具有对应关系，可以是具体的信道质量门限值对应某种上报方式，也可以是信道质量门限值的区间对应某种上报方式，本申请实施例对此不作限定。此外，上述对应关系可以为该终端设备与该网络设备提前协商好的，也可以是该网络设备告知终端设备的，该对应关系可以在该网络设备向该终端设备发送信道质量门限值之前发送，也可以与该信道质量门限值一起发送，本申请实施例对此也不作限定。
作为一个可选的实施例，在S230，所述终端设备根据所述信道质量门限值，向所述网络设备发送第一数目的所述第一信道质量信息之前，所述方法还包括：
该终端设备接收该网络设备发送的第二数目，所述第二数目用于表示所述网络设备为所述终端设备配置的所述第一信道质量信息的数目；
则对应的，所述网络设备向所述终端设备发送第二数目；
S230，所述终端设备根据所述信道质量门限值，向所述网络设备发送第一数目的所述第一信道质量信息，包括：
所述终端设备根据所述信道质量门限值以及所述第二数目，向所述网络设备发送所述第一数目的所述第一信道质量信息，所述第一数目小于或者等于所述第二数目；
则对应的，所述网络设备接收所述终端设备根据所述信道质量门限值以及所述第二数目，发送的所述第一数目的所述第一信道质量信息。
可选的，该第二数目取值可以为1、2、4中的任意一个。
具体的，该网络设备在为该终端设备配置信道质量门限值的同时，还可以向该终端设备配置需要上报的该第一信道质量信息的数目，即第二数目，应理解，该第二数目即为该网络设备请求该终端设备上报的第一信道质量信息的数目。该终端设备可以接收该网络设备发送的该第二数目，然后根据所述信道质量门限值以及所述第二数目发送第一数目的第一信道质量信息，因此，该第一数目可以小于或者等于该第二数目。
例如，若该网络设备请求该终端设备上报5个最优参考信号的第一信道质量信息，但该终端设备将所有参考信号扫描和检测完毕之后，发现仅存在3个第二信道质量信息超出上述信道质量门限值的参考信号，那么，该终端设备可以将所述3个参考信号对应的第一信道质量信息发送给该网络设备。假定每个第一信道质量信息中包括参考信号索引和参考信号接收功率RSRP，其中每个参考信号索引的上报比特数为9bits，每个RSRP的上报比特数为7bits。对于网络设备为该终端设备配置5个参考信号的第一信道质量信息，而该终端设备实际上报了3个参考信号的第一信道质量信息的情况，该终端设备可以节省(9+7)×2＝32bits。
因此，通过本申请实施例的信号传输方法，能够避免该终端设备进行不必要的信道质量信息的上报，节省该终端设备的信令开销。
此外，应理解，若终端设备采用依次上报的方式，那么该终端设备在对网络设备发送 的多个参考信号进行扫描时，如果在开始阶段已经基于对所述多个参考信号的信道质量测量，根据信道质量门限值和该网络设备配置的第二数目(假设为N)找到了N个满足上述信道质量门限值的参考信号，并进行了所述N个参考信号的第一信道质量信息的上报，则该终端设备可以停止对后续参考信号的扫描和对应的信道质量测量。同时当网络设备发现所述终端设备上报的信道质量信息数目已经等于N时，其可停止接下来参考信号的发送。
此外，在该网络设备未向该终端设备配置需要该终端设备上报的第二数目的情况下，该网络设备可以基于该终端设备上报的信道质量信息的数目，确定是否继续进行接下来参考信号的发送。
由此可见，本申请实施例不仅能够降低终端设备的上报资源开销，还可以降低网络设备的发射资源开销，同时减小终端设备的处理复杂度。
作为一个可选的实施例，所述网络设备向所述终端设备发送第二数目，包括：
所述网络设备向所述终端设备发送第一信令，所述第一信令携带所述第二数目，且所述第一信令为高层信令或物理层信令。
作为一个可选的实施例，所述网络设备向终端设备发送信道质量门限值，包括：
所述网络设备向所述终端设备发送第二信令，所述第二信令携带所述信道质量门限值，且所述第二信令为高层信令和/或物理层信令。
具体的，该网络设备向该终端设备配置该第二数目以及该信道质量门限值，可以分为如下四种情况：
(1)该网络设备可以通过高层信令向该终端设备发送该第二数目，通过高层信令向该终端设备发送该信道质量门限值；
(2)该网络设备可以通过物理层信令向该终端设备发送该第二数目，通过物理层信令向该终端设备发送该信道质量门限值；
(3)该网络设备可以通过高层信令向该终端设备发送该第二数目，通过物理层信令向该终端设备发送该信道质量门限值；
(4)该网络设备可以通过物理层信令向该终端设备发送该第二数目，通过高层信令向该终端设备发送该信道质量门限值。
可选地，该网络设备向该终端设备发送信道质量门限值，可以通过高层信令和物理层信令结合的方式，即上述第二信令可以包括高层信令和物理层信令。具体的，该网络设备可以通过高层信令向该终端设备发送多个候选信道质量门限值以及该多个候选信道质量门限值中每个候选信道质量门限值对应的门限值标识，通过物理层信令向该终端设备发送第一门限值标识，该第一门限值标识即为多个候选信道质量门限值中该网络设备为该终端设备配置的信道质量门限值。该终端设备在接收到上述第二信令之后，可以根据第一门限值标识确定出该网络设备为该终端设备配置的信道质量门限值。
例如，该网络设备可以通过高层信令向该终端设备发送多个候选信道质量门限值{-70，-80，-90，-100}以及每个候选信道质量门限值对应的门限值标识{1，2，3，4}；该网络设备可以通过物理层信令向该终端设备发送第一门限值标识2,。该终端设备接收到上述高层信令以及物理层信令之后，就可以根据第一门限值标识2，确定出该网络设备为该终端设备配置的信道质量门限值为-80。
这样，网络设备无需在物理层信令中携带过多的信息，能够节省物理层信令的信令开 销。
应理解，该高层信令可以为无线资源控制(radio resource control，RRC)信令，该物理层信令可以为下行控制信息(downlink control information，DCI)信令，该高层信令以及该物理层信令还可以为其他信令，本申请实施例对此不作限定。此外，该网络设备发送该第二数目以及该信道质量门限值还可以采用其他信令的任意组合，本申请实施例对此也不作限定。
作为一个可选的实施例，所述网络设备接收所述终端设备根据所述信道质量门限值发送的第一数目的所述第一信道质量信息，包括：
所述网络设备接收所述终端设备根据所述信道质量门限值发送的所述第一数目以及所述第一数目的所述第一信道质量信息。
则对应的，S230可以为该终端设备将第一数目以及该第一数目的该第一信道质量信息发送给该网络设备。
具体的，对于该终端设备在确定满足信道质量门限值的第一数目的参考信号的第二信道质量信息时，将该第一数目的参考信号对应的第一信道质量信息一起发送给该网络设备的情况，该终端设备可以将确定的第一数目发送给该网络设备，该网络设备可以根据该终端设备发送的第一数目确定该终端设备发送的第一信道质量信息的大小以及长度，从而便于对接收到的第一信道质量信息进行相应的解码操作。
作为一个可选的实施例，在S220，所述终端设备根据所述信道质量门限，向所述网络设备发送第一数目的所述第一信道质量信息之前，所述方法还包括：
所述终端设备根据所述信道质量门限值以及所述第二数目，确定所述第一数目；
S220，所述终端设备根据所述信道质量门限，向所述网络设备发送第一数目的所述第一信道质量信息，包括：
所述终端设备向所述网络设备发送所述第一数目以及所述第一数目的所述第一信道质量信息；
则对应的，所述网络设备接收所述终端设备发送的所述第一数目以及所述第一数目的第一信道质量信息。
应理解，若该终端设备不向该网络设备发送待上报的第一信道质量信息的数目，该终端设备需要以一次能够传输的最大长度来对待发送的第一信道质量信息进行编码发送给该网络设备，以便于该网络设备进行解码。而本实施例终端设备可以根据实际情况进行上报，该网络设备可以根据该终端设备发送的第一数目确定该终端设备上报的第一信道质量信息的个数，并进行解码，从而节省了该终端设备的上报开销。
作为一个可选的实施例，所述终端设备向所述网络设备发送所述第一数目以及所述第一数目的所述第一信道质量信息，包括：
所述终端设备对所述第一数目以及所述第一数目的所述第一信道质量信息分别进行编码；
所述终端设备向所述网络设备发送编码后的所述第一数目以及编码后的所述第一数目的所述第一信道质量信息。
具体的，由于该终端设备每次发送第一信道质量信息的数目不固定，在发送该第一信道质量信息时可以根据实际的数目动态调整编码长度以及大小，因此，该终端设备在向该 网络设备发送该第一数目以及该第一数目的第一信道质量信息时，可以将该第一数目进行单独编码，这样，该网络设备在接收到该第一数目以及该第一数目的第一信道质量信息后，可以先将该第一数目进行解码，确定出该终端设备发送了多少份第一信道质量信息，然后再对该第一信道质量信息进行解码。因此，对第一数目进行单独编码能够方便该网络设备尽快获取到所述第一数目，并根据所述第一数目进行相应的第一信道质量信息的解码。
应理解，该终端设备也可以将该第一数目与该第一数目的第一信道质量信息进行联合编码，本申请实施例对此不作限定。
作为一个可选的实施例，在所述网络设备接收所述终端设备根据所述信道质量门限值发送的第一数目的所述第一信道质量信息之前，所述方法还包括：
所述网络设备向所述终端设备发送第一通知消息，所述第一通知消息用于通知所述网络设备到所述终端设备的参考信号的发送；
则对应的，该终端设备接收该网络设备发送的该第一通知消息。
具体的，该网络设备在向该终端设备发送参考信号之前，可以先向该终端设备发送第一通知消息，用于通知该终端设备该网络设备在接下来的P(P为大于或等于1的整数)个连续的参考信号发射时刻向该终端设备发送参考信号，以便于该终端设备能够做好准备，及时接收该网络设备发送的参考信号，并对该参考信号对应的信道质量进行测量。
作为一个可选的实施例，所述方法还包括：
所述网络设备向所述终端设备发送第二通知消息，所述第二通知消息用于通知所述网络设备到所述终端设备的参考信号的发送终止；
则对应的，该终端设备接收该网络设备发送的该第二通知消息。
具体的，该网络设备可以向该终端设备发送第二通知消息，用于通知该终端设备该网络设备停止进行参考信号的发送。应理解，对于该终端设备分别上报满足所述信道质量门限值的每个参考信号的第一信道质量信息的情况，若该网络设备已经确定了足够的第一数目的第一信道质量信息，便可以向该终端设备发送第二通知消息，该终端设备接收到该第二通知消息之后，便不会再进行参考信号的接收及基于所述参考信号的信道质量的测量，也不会再向该网络设备上报第一信道质量信息。这样，在一定程度降低了终端设备的上报开销，减小了该终端设备的处理复杂度。
应理解，所述网络设备也可以在接收所述终端设备根据所述信道质量门限值发送的第一数目的所述第一信道质量信息之前，向所述终端设备发送第二通知消息，所述第二通知消息用于通知所述网络设备到所述终端设备的参考信号的发送终止。即，所述信道质量信息的上报在所述网络设备向所述终端设备发送第二通知消息之后。
作为一个可选的实施例，所述第一信道质量信息为下列信息中的至少一种：
参考信号索引、与所述参考信号索引对应的参考信号接收功率(reference signal received power，RSRP)、与所述参考信号索引对应的参考信号接收质量(reference signal received quality，RSRQ)以及与所述参考信号索引对应的信道质量指示(channel quality indication，CQI)，其中，所述参考信号索引用于表示与所述第一信道质量信息对应的参考信号。
应理解，所述第一信道质量信息可以为LTE中的CSI信息，例如信道状态信息参考信号指示符(CSI-RS index，CRI)、秩指示(rank indicator，RI)、预编码矩阵指示(precoding  matrix indicator，PMI)、CQI等等中的至少一个，或者该第一信道质量信息还可以为无线资源管理(radio resource management，RRM)测量的信道质量信息，例如RSRP、RSRQ等等中的至少一个。此外，该第一信道质量信息还可以为上述信息外的其他任意一种或多种信道质量信息，或者包括上述信息之外还包括其他任意一种或多种信道质量信息，本申请实施例对此不作限定。
作为一个可选的实施例，所述第二信道质量信息为参考信号接收功率RSRP、参考信号接收质量RSRQ或信道质量指示CQI。
具体的，该第二信道质量信息为触发量，因此，该第二信道质量信息为任意一种信道质量信息。应理解，该第二信道质量信息可以为上述CRI、RI、PMI、CQI、RSRP、RSRQ中的任意一种，或者为其他任意的一种信道质量信息，本申请实施例对此不作限定。
作为一个可选的实施例，所述终端设备根据所述信道质量门限，向所述网络设备发送第一数目的所述第一信道质量信息，包括：
所述终端设备通过物理上行控制信道PUCCH和/或物理上行共享信道PUSCH向所述网络设备发送所述第一数目的所述信道质量信息。
图3示出了本申请实施例提供的信号传输方法300的示意性流程图。该方法300可以应用于图1所示的系统架构100，但本申请实施例不限于此。网络设备先向终端设备发送第一通知消息，用于通知该终端设备该网络设备在接下来的P(P为大于或等于1的整数)个连续的参考信号发射时刻发送参考信号。接着，该网络设备如图3所示进行参考信号的发送，该终端设备接收该网络设备发送的参考信号1，在接收的同时对该参考信号1对应的信道质量进行测量，获得上述第一信道质量信息以及第二信道质量信息。在第二信道质量信息满足信道质量门限的情况下，该终端设备向该网络设备发送该参考信号1的第一信道质量信息。应理解，该终端设备在上报参考信号1的同时仍在接收其他参考信号，并同时进行检测。若该终端设备检测到参考信号i的第二信道质量信息满足信道质量门限，那么该终端设备向该网络设备上报该参考信号i的第一信道质量信息。该网络设备分别接收到参考信号1和参考信号i的第一信道质量信息之后，认为不需要再进行信道质量的测量，便会停止参考信号的发送，并向该终端设备发送第二通知消息，用于通知该终端设备该网络设备停止参考信号的发送。
因此，本申请实施例的信号传输方法，能够在降低终端设备的上报资源开销的同时，降低网络设备的发射资源开销，减小终端设备的处理复杂度，从而提高用户体验。
