具体实施方式
下面详细描述本申请的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
为了便于理解，首先介绍本申请涉及的术语。
1、无线信道(Wireless channel)
是对无线通信中发送端和接收端之间通路的一种形象比喻，对于无线电波而言，它从发送端传送到接收端，其间并没有一个有形的连接，它的传播路径也有可能不只一条，我们为了形象地描述发送端与接收端之间的工作，可以想象两者之间有一个看不见的道路衔接，把这条衔接通路称为信道。
2、无线资源控制(Radio Resource Control，RRC)
RRC又称为无线资源管理(Radio Resource Management，RRM)或者无线资源分配(Radio Resource Allocation，RRA)，是指通过一定的策略和手段进行无线资源管理、控制和调度，在满足服务质量的要求下，尽可能地充分利用有限的无线网络资源，确保到达规划的覆盖区域，尽可能地提高业务容量和资源利用率。
3、信道估计(channel estimation)
从接收数据中将假定的某个信道模型的模型参数估计出来的过程。如果信道是线性的话，那么信道估计就是对***冲激响应进行估计。需强调的是，信道估计是信道对输入信号影响的一种数学表示，而“好”的信道估计则是使得某种估计误差最小化的估计算法。
4、频偏(frequency offset)
是调频波里的特有现像，是指固定的调频波频率向两侧的偏移，是调频波频率摆动的幅度，一般说的是最大频偏，它影响调频波的频谱带宽。
5、路径损耗(Path loss)
或称传播损耗，指电波在空间传播所产生的损耗，是在发射器和接收器之间由传播环境引入的损耗的量，是由发射功率的辐射扩散及信道的传播特性造成的。
6、资源块(Resource blocks，RB)
数据信道资源分配的频域基本调度单位，频域上是12个子载波，是一个频域概念，没有定义时域。

下面结合附图对本申请所提出的一种联合信道估计方法及装置进行详细的介绍。
图2为本申请一实施例的联合信道估计方法的流程示意图，该方法应用于终端设备，如图2所示，该方法包括：
S201，获取联合信道估计窗的窗口数量。
为了获取无线信道的参数信息，可以采用信道估计的方法，一般情况下，可以多个无线信道与网络设备之间进行传输。为了提高信道估计的效率，可以针对多个无线信道进行联合信道估计，进而提高信道估计的效率。
联合信道估计，是指针对一个以上数量的无线信道进行的信道估计，实现中，每一次的联合信道估计的无线信道的数量由联合信道估计窗的窗口数量(bundle size)决定。联合信道估计窗的窗口数量限定了联合信道估计所涉及的无线信道数量。
本申请实施例中，终端设备可以获取到联合信道估计窗的窗口数量，在一些实现中，可以通过协议约定联合信道估计窗的窗口数量。在另一些实现中，终端设备可以基于网络侧的指示来获取联合信道估计窗的窗口数量。比如，终端设备可以接收网络设备发送的指示信息，该指示信息可以指示联合信道估计窗的窗口数量。该指示信息可以由控制信令，如下行控制信息(downlink control information，DCI)信令或者其他信令承载。
S202，在每个联合信道估计窗内采用相同的频率资源和预编码方式进行传输。
网络设备通过接收无线信道传输的信号，获取到无线信道的参数信息，进而实现对于无线信道的信道估计。
本申请实施例中，终端设备在获取到联合信道估计窗的窗口数量之后，就可以确定在联合信道估计过程中所涉及的联合信道估计窗的数量。进一步地，终端设备在每个联合信道估计窗内与网络设备进行数据或者信息的传输，使得网络设备可以基于接收到的传输进行联合信道估计。为了保证联合信道估计的准确性，终端设备可以在每个联合信道估计窗内相同的采用的频率资源和预编码方式，向网络设备传 输数据或者信息。通过采用相同传输方式向网络设备进行传输，可以保证联合信道估计结果的准确性，可以避免由于传输方式不同而导致的联合信道估计不准确的问题。
本申请提出的联合信道估计方法，终端设备获取到联合信道估计窗的窗口数量后，在每个联合信道估计窗内采用相同的频率资源和预编码方式进行传输。本申请中，使用联合信道估计窗的窗口实现针对多个无线信道的联合信道估计，提高了信道估计的效率，进一步地，采用相同的频率资源和预编码方式进行信号传输，保证了联合信道估计的准确性，有效提高传输的可靠性，进而精准的获取覆盖的参数信息。
图3为本申请另一实施例的联合信道估计方法的流程示意图，该方法应用于终端设备，该方法包括：
S301，接收来自网络设备的配置信令，配置信令包括以下至少一个：联合信道估计的最大传输次数；和联合信道估计窗的多个候选窗口数量。
本申请实施例中，终端设备可以接收网络设备发送的配置信令，配置信令可以包括联合信道估计的最大传输次数和/或联合信道估计窗的多个候选窗口数量，可选地，配置信令可以为高层信令，比如，配置信令可以是无线资源控制(Radio Resource Control，RRC)信令。
在一些实现中，配置信令可以包括联合信道估计窗的多个候选窗口数量。需要说明的是，网络设备可以通过另外的信令向终端设备指示用于联合信道估计的最大传输次数或者通过协议约定用于联合信道估计的最大传输次数。在另一些实现中，配置信令可以包括联合信道估计的最大传输次数和联合信道估计窗的多个候选窗口数量。其中，多个候选窗口数量可以形成一个配置集合。可以理解为，终端设备可以接收同时携带最大传输次数和配置集合的配置信令。在另一些实现中，配置信令可以先发送最大传输次数，再发送联合信道估计窗的多个候选窗口数量。
当网络设备发送的配置信令携带多个联合信道估计窗的窗口数量时，终端设备基于配置信令可以获取到多个联合信道估计窗的窗口数量作为候选。
S302，接收来自网络设备的控制信令，控制信令用于激活候选窗口数量中的一个作为联合信道估计窗的窗口数量。
本申请实施例中，终端设备接收来自网络设备的控制信令，并基于多个联合信道估计窗的候选窗口数量中，激活其中一个作为本次联合信道估计窗的窗口数量。
可选地，控制信令可以为DCI信令或者其他信令。
终端设备基于获取到的网络设备发送的控制信令激活联合信道估计窗的窗口数量后，可以根据联合信道估计的最大传输次数，在联合信道估计窗的窗口内采用相同的频率资源与预编码方式进行信号传输。
比如，设定联合信道估计的最大传输次数为16次，联合信道估计窗的候选窗口数量分别为2、4、8，网络设备的控制信令激活多个候选窗口数量中的8作为联合信道估计窗的窗口数量，则终端设备采用相同的频率资源以及预编码方式，在8个联合信道估计窗的窗口内进行信号传输，每个联合信道估计窗的窗口传输2次。
再比如，设定联合信道估计的最大传输次数为32次，联合信道估计窗的候选窗口数量分别为2、4、8、16，网络设备的控制信令激活多个候选窗口数量中的4作为联合信道估计窗的窗口数量，则终端设备采用相同的频率资源以及预编码方式，在4个联合信道估计窗的窗口内进行信号传输，每个联合信道估计窗的窗口传输8次。
S303，在每个联合信道估计窗内采用相同的频率资源和预编码方式进行传输。
本申请实施例中，终端设备需要保证在每个联合信道估计窗的窗口内采用相同的频率资源和预编码方式进行传输。在一些实现中，终端设备传输时占用频率资源块(Resource blocks，RB)上相同的开始位置，并且采用相同的预编码方式，可以理解为，在联合信道估计的最大传输次数的每一次传输中，终端设备需要在每个联合信道估计窗内占用频率RB上相同的开始位置，并且在联合信道估计的最大传输次数的每一次传输中，终端设备需要在每个联合信道估计窗内采用相同的预编码方式。
本申请提出的联合信道估计方法，终端设备基于获取到的网络设备发送的配置信令，配置多个联合信道估计窗的候选窗口数量，并基于接收到的网络设备发送的控制信令激活多个联合信道估计窗的候选窗口数量中的一个作为本次联合信道估计窗的窗口数量，进一步地，结合联合信道估计的最大传输次数，在每一个联合信道估计窗的窗口内采用相同的频率资源以及预编码方式进行传输。其中，每一个联合信道估计窗的窗口内的传输均占用频率资源块上相同的起始位置。本申请中，通过联合信道估计窗的窗口数量实现了多个无线信道的信道估计，提高了信道估计的效率，基于网络设备的配置信令，有效地确定了联合信道估计窗的窗口数量，根据最大传输次数配置每个联合信道估计窗的窗口内的传输次数，保证了联合信道估计的可实施性，采用相同的频率资源以及预编码方式，最大限度的避免了其他因素对于信道估计结果的影响，保证了联合信道估计的准确性，有效提高传输的可靠性，进而精准的获取覆盖参数信息。
图4为本申请另一实施例的联合信道估计方法的流程示意图，该方法应用于终端设备，该方法包括：
S401，接收来自网络设备的配置信令，配置信令包括以下至少一个：联合信道估计的最大传输次数；和联合信道估计窗的一个候选窗口数量。
本申请实施例中，终端设备可以接收网络设备发送的配置信令，配置信令可以包括联合信道估计的最大传输次数和/或联合信道估计窗的一个候选窗口数量，可选地，配置信令可以为高层信令，比如，配置信令可以是RRC信令或者其他信令。
在一些实现中，配置信令可以包括联合信道估计窗的一个候选窗口数量。需要说明的是，网络设备可以通过另外的信令向终端设备指示用于联合信道估计的最大传输次数或者通过协议约定用于联合信道估计的最大传输次数。在另一些实现中，配置信令可以包括联合信道估计的最大传输次数和联合信道估计窗的一个候选窗口数量。可以理解为，终端设备可以接收同时携带最大传输次数和联合信道估计窗的候选窗口数量配置的配置信令。在另一些实现中，配置信令可以先发送最大传输次数，再发送联合信道估计窗的一个候选窗口数量。
当网络设备发送的配置信令携带一个联合信道估计窗的窗口数量时，终端设备基于配置信令可以获取到一个联合信道估计窗的窗口数量作为候选。
S402，接收来自网络设备的控制信令，控制信令用于激活候选窗口数量中的一个作为联合信道估计窗的窗口数量。
本申请实施例中，终端设备基于获取到的配置信令，可以确定联合信道估计中联合信道估计窗的窗口数量。进一步地，结合信道联合估计的最大传输次数，在联合信道估计窗的窗口内采用相同的频率资源与预编码方式进行信号传输。
比如，设定联合信道估计的最大传输次数为8次，则联合信道估计窗的窗口数量为8，则终端设备采用相同的频率资源以及预编码方式，在8个联合信道估计窗的窗口内进行信号传输，每个联合信道估计窗的窗口传输1次。
再比如，设定联合信道估计的最大传输次数为4次，则联合信道估计窗的窗口数量为4，则终端设备采用相同的频率资源以及预编码方式，在4个联合信道估计窗的窗口内进行信号传输，每个联合信道估计窗的窗口传输1次。
S403，在每个联合信道估计窗内采用相同的频率资源和预编码方式进行传输。
步骤S403可参加上述相关详细内容，此处不再赘述。
本申请提出的联合信道估计方法，终端设备基于获取到的网络设备发送的配置信令，配置一个联合信道估计窗的候选窗口数量，并基于接收到的网络设备发送的控制信令激活该联合信道估计窗的候选窗口数量作为本次联合信道估计窗的窗口数量，进一步地，结合联合信道估计的最大传输次数，在每一个联合信道估计窗的窗口内采用相同的频率资源以及预编码方式进行传输。本申请中，通过联合信道估计窗的窗口数量实现了多个无线信道的信道估计，提高了信道估计的效率，基于网络设备的配置信令，有效地确定了联合信道估计窗的窗口数量，根据最大传输次数配置每个联合信道估计窗的窗口内的传输次数，保证了联合信道估计的可实施性，采用相同的频率资源以及预编码方式，最大限度的避免了其他因素对于信道估计结果的影响，保证了联合信道估计的准确性，有效提高传输的可靠性，进而精准的获取覆盖参数信息。
为了抵御某些频率的干扰，保证传输的质量，终端设备可以基于网络设备的信令激活跳频机制，如图5所示，图5为本申请另一实施例的联合信道估计方法的流程示意图，该方法应用于终端设备，该方法包括：
S501，接收来自网络设备的配置信令，配置信令包括以下至少一个：联合信道估计的最大传输次数；和联合信道估计窗的一个或者多个候选窗口数量。
S502，终端设备接收来自所述网络设备的控制信令，所述控制信令用于激活候选窗口数量中一个作为联合信道估计窗的窗口数量。
步骤S501～S502可参加上述相关详细内容，此处不再赘述。
S503，响应于跳频机制被激活且配置有一个频率偏移量，在每个联合信道估计窗内按照频率偏移量跳频后进行传输。
实现中，无线信道的传输环境存在较多的客观因素的干扰，比如，传输路径上所经过的建筑、植物、金属体、空气等等，不同频率的路径损耗存在不同，为了抵御某些频率上可能产生的较高的路径损耗，保证无线信道的传输质量，可以采用跳频机制进行信号传输。网络设备可以基于获取到的每个联合信道估计窗的窗口内的传输信号质量，发送跳频机制激活的信令至终端设备。响应于跳频机制的激活，终端设备可以为每个联合信道估计窗的窗口配置频率偏移量。
本申请实施例中，终端设备基于获取到的跳频机制激活的信令，为每个联合估计信道窗的窗口配置一个频率偏移量。所配置的频率偏移量，可以理解为，本次联合信道估计窗的窗口内传输所占用的频率与上一次联合信道估计窗的窗口内的传输所占用的频率之差。
比如，设定频率偏移量为Z，本次联合信道估计窗的窗口传输所占用的频率为A，基于跳频机制，则下一次的联合信道估计窗的窗口传输所占用的频率为B＝A+Z，再下一次联合信道估计窗的窗口传输所占用的频率又跳回A。
在上一次的联合信道估计窗的窗口内的传输结束后，终端设备基于已经设置好的频率偏移量调整每个联合信道估计窗的窗口内的传输所占用的频率，并使用调整后的频率，在每个联合信道估计窗的窗口 内采用相同的频率资源和预编码方式进行新一轮的传输。
S504，响应于跳频机制被激活且配置有两个频率偏移量，确定奇数号的联合信道估计窗和偶数号的联合信道估计窗分别对应两个频率偏移量中的一个；以及在每个联合信道估计窗内按照各自对应的频率偏移量跳频后进行传输。
本申请实施例中，为了更好的抵御某些频率的干扰，终端设备基于获取到的网络设备发送的跳频机制激活的信令，可以配置两个频率偏移量。联合信道估计中，可以为涉及的每个联合信道估计窗的窗口进行排序以及编号，使得偶数编号的联合信道估计窗的窗口与奇数编号的联合信道估计窗的窗口可以分别对应不同的频率偏移量。
比如，设定频率偏移量为X和Y，联合信道估计窗的窗口数量为14，奇数编号的联合信道估计窗的窗口对应的频率偏移量为X，偶数编号的联合信道估计窗的窗口对应的频率偏移量为Y，将联合信道估计窗的14个窗口进行排序编号，则编号为1、3、5、7、9、11、13的联合信道估计窗的窗口的频率偏移量为X，编号为2、4、6、8、10、12、14的联合信道估计窗的窗口的频率偏移量为Y。
本次奇数编号的联合信道估计窗的窗口传输所占用的频率为M，偶数编号的联合信道估计窗的窗口传输所占用的频率为N，则下一次的奇数编号的联合信道估计窗的窗口传输所占用的频率为P＝M+X，再下一次奇数编号的联合信道估计窗的窗口传输所占用的频率又跳回M。
下一次的偶数编号的联合信道估计窗的窗口传输所占用的频率为Q＝N+Y，再下一次奇数编号的联合信道估计窗的窗口传输所占用的频率又跳回N。
在每次的联合信道估计窗的窗口传输结束后，终端设备根据联合信道估计窗的窗口对应的不同的频率偏移量进行跳频，并在跳频后所占用的频率上进行下一次传输。
需要说明的是，在完成调频后进行的传输仍然遵循在每个联合信道估计窗的窗口内采用相同的频率资源和预编码方式进行传输的原则。
本申请提出的联合信道估计方法，基于网络设备发送的跳频机制激活信令，为联合信道估计窗的窗口配置频率偏移量，本次联合信道估计窗的窗口内传输结束后，基于配置的频率偏移量，调整联合信道估计窗的窗口传输所占用的频率，并使用调整后的频率在联合信道估计窗的窗口内进行下一次的传输。其中，当频率偏移量设置为两个时，可以为每个联合信道估计窗的窗口进行排序和编号，使得奇数编号的联合信道估计窗的窗口与偶数编号的联合信道估计窗的窗口可以对应不同的频率偏移量。本申请中，使用跳频机制进行联合信道估计窗的窗口内传输，可以有效抵御某些频率对于传输的影响，保证了无线信道内的传输质量，提高传输的可靠性，进而保证了联合信道估计的准确性。
为了保证上述实施例可以实施，本申请还提出一种联合信道估计方法，应用于网络设备，如图6所示，图6为本申请另一实施例的联合信道估计方法的流程示意图，该方法包括：
S601，向终端设备发送联合信道估计窗的窗口数量。
联合信道估计所涉及的无线信道数量由网络设备决定，网络设备可以基于相关参数决定联合信道估计所涉及的联合信道估计窗的窗口数量并通过特定信令发送给终端设备。其中，特定信令可以为控制信令，比如，DCI信令等等。
S602，接收终端设备在每个联合信道估计窗内采用相同的频率资源和预编码方式进行的传输。
