Description

信号发送、接收发送、装置和计算机存储介质 技术领域
本发明涉及通信领域，尤其涉及一种信号发送、接收发送、装置和计算机存储介质。
背景技术
在长期演进(Long-Term Evolution，简称为LTE)中，有很多周期的参考信号，比如同步信号，小区参考信号，信道测量参考信号，上行探测参考信号等，用户设备可根据高层信令配置的周期来接收或者发送这些周期参考信号。周期的参考信号配置简单，只需要基站用高层信令半静态配置，而不需要额外的动态信令通知。然而，周期的参考信号发送会给系统带来很大的开销。所以LTE中同时进入了一些非周期的参考信号，比如非周期的上行探测参考信号，基站可用高层信令(例如，无线资源控制信令)配置一个或者多个探测参考信号配置，其中配置参数包括发送带宽，时频位置，序列循环移位等参数，进而基站可根据需求来决定是否在物理层控制区域上触发上行探测参考信号的发送。这就是非周期的探测参考信号。
在5G新无线(new radio)中，由于用户设备的数据量需求增加，为了减少开销，尤其是探测参考信号的开销，引入非周期的参考信号是一种趋势。比如，非周期的信道探测参考信号。
另外，LTE是不需要波束参考信号的。这是由于LTE基站或者用户设备在发送参考信号时往往用的是一个很宽的射频波束来达到小区级覆盖。
图1-a是相关技术中发送参考信号时的射频波束的小区级覆盖图。
因为LTE用的载波频率基本上是6GHz以下，所以利用多天线阵子形 成的宽射频波束能够覆盖整个小区。而在5G中，不仅要支持6GHz以下的载波频段，还要支持6GHz以上的频段，例如60GHz。由于在高频段大尺度路径损耗非常大，这给无线通信带来了很大的挑战。但是由于在高频段中心频率高，波长短，基站可容纳的天线数量很多并且利用多个天线来形成很窄的波束来形成波束赋型增益。所以窄射频波束赋型几乎成了高频段增强小区覆盖的必不可少的技术。而到底给用户设备配置那个波束，就有可能需要基站发送波束参考信号以用于用户设备测量最佳的波束。图1-b是相关技术中不同的参考信号对应不同的波束方向示意图。
基站可触发或者周期的发送波束参考信号，其中不同的参考信号对应不同的波束方向。UE在测量波束参考信号后可反馈一个或者多个最佳波束序号给基站，这样基站在后续发送数据时可利用最佳波束来发送数据给特定的用户设备。
如向前面所说的，非周期的送波束参考信号的引入也会节省系统的导频开销。
此外，对于波束测量参考信号以及其他类似的参考信号，动态激活的方式也可能引入5G中。比如基站可利用物理层动态信令激活波束参考信号的发送，激活后基站将会按照高层信令配置而发送周期的或者多个波束参考信号。
图2-a是相关技术中下行参考信号的触发示意图。如果是下行参考信号的触发，基站在子帧n的物理层控制区域上触发某参考信号后，基站将会在子帧n+m上发送，此时假定子帧n+m是下行子帧。而如果是上行参考信号的触发，基站在子帧n的物理层控制区域上触发某参考信号后，用户设备将会在子帧n+m上发送，其中子帧n+m包含上行发送区域。
为了支持灵活的子帧配置，一般的，m的候选值可以是多个，比如0，1，2，3。基站在触发参考信号时会动态通知m具体的值。如果m＝0，那 么触发参考信号的DCI和发送的参考信号就在一个子帧中。
UE是否需要将测量结果反馈，以及在哪个子帧中反馈测量结果可能也需要在动态信令中包含。一般的，基站可利用动态信令通知用户设备在测量参考信号后的k个子帧将测量结果反馈给基站。图2-b是相关技术中测量结果反馈示意图，如图2-b所示，基站在子帧n的物理层控制区域上触发某下行测量参考信号后，基站将会在子帧n+m上发送，同时基站在子帧n中触发了测量结果反馈的，这样用户设备会在子帧n+m+k上发送测量结果给基站。
为了支持灵活的子帧配置，一般的，k的候选值可以是多个，比如0，1，2，..7。比如如果k＝0时是下行子帧，那么基站就不能配置k＝0，因为此时用户设备不可能利用下行子帧来发送上行的数据。
这种动态的触发参考信号以及反馈给系统带来了很大的灵活性，同时也给系统带来了一定的困扰。如图2-a所示，基站在子帧n中触发了参考信号1在子帧n+3上发送，此时m＝3，而基站又在子帧n+1中触发了参考信号2在子帧n+3上发送，此时m＝2。这样，如果参考信号1和参考信号2资源位置重叠的话，会对用户设备的测量以及反馈带来困扰。
针对相关技术中存在的上述问题，目前尚未发现有效的解决方案。

实施例3
本实施例是根据本发明的可选实施例，用于结合具体的实例对本申请进行详细说明：
本实施例提出了一种参考信号触发及其反馈优先级排序的方法，包括：
发送端在时间单元n1里触发信号s1在时间单元n1+m1上发送或者接收，并
且发送端在时间单元n2上触发信号s2在时间单元n2+m2上发送或者接收。如果信号s1和s2所在的资源位置有重叠时，按照一定的优先级规则接收或者发送信号s1和s2。
信号s1和s2如果是参考信号，包括信道测量参考信号，波束参考信号，上行探测参考信号，预编码的信道测量参考信号等。
上述一个时间单元可以是1个子帧，，或者一个时隙，或者一个最小调度时域单元。且信号s1，信号s2对应的发送的实际时间单元可以不一样。比如信号s1在标准时隙上发送，而信号s2在一个短时隙(mini slot)上发送；所述短时隙的时长短于所述短时隙的时长。例如，所述标准时隙包括的传输符号(例如，OMFD)的个数多于短时隙包括的传输符号的个数。通常，所述短时隙最少包括一个传输符号。下行发送端指的是基站，而接收端指的就是用户设备终端，而上行发送端指的是用户设备，而接收端指的是基站。不管上行还是下行，都是由基站来做触发的。对于这些参 考信号，基站可利用高层信令配置参考信号在一个子帧中的资源位置，即时频位置，比如在一个子帧中的哪些时域正交频分复用(Orthogonal Frequency Division Multiplexing，简称为OFDM)符号上，还有带宽长度，比如参考符号是系统带宽的几分之几，还有参考符号的密度，比如每个物理资源块(Physical Resource Block，简称为PRB)都发送，还是每两个PRB发送一次等。再高层信令配置好这些参数后，基站可利用下行控制信息(Downlink Control Information，DCI)比特(bit)来触发是否发送参考信号，以及在后面哪个子帧中发送。当然，基站可通过RRC信令配置给用户设备多个参考信号配置参数，然后基站可通过DCI的bit信息触发其中一个。
也就是说，基站在DCI中包含的信息有是否触发某参考信号以及参考信号在后面哪个子帧、时隙或短时隙中发送。如图2-a所示，在子帧n中，基站用DCI触发了下行测量参考信号，然后同时DCI中包含了一些信息位来告诉用户设备m的值，在子帧n+m时，基站会发送该测量参考信号。该测量参考信号的时频位置，带宽，密度等参数需要根据高层信令指示来得知。
图9是本实施例的优先级排序示意图，如图9所示，发送时间单元n1就是子帧n，而发送单元n2就是子帧n+1，m1＝3，m2＝2。基站在子帧n1上触发了测量参考信号s1，而在子帧n2上触发了测量参考信号s2。s1和s2可以是同一类型的测量参考信号，比如都是下行信道测量参考信号(Channel State Information-Reference Signals，CSI-RS)，高层信令配置给s1和s2的时频位置，带宽，密度等参数可以相同，也可以不同。如果s1和s2的时频位置有重叠，那么根据优先级规则，优先级低的参考信号可以被舍弃。也就是说，此时n1+m1＝n2+m2，并且基站只发送优先级最高的参考信号，而舍弃优先级低的参考信号。
当然，s1和s2是同一类型的参考信号，但是高层信令配置可以不同。比如对于CSI-RS，高层信令配置了多种配置，在子帧n1中，DCI触发了一种配置参数，而在子帧n2中，DCI触发了另外一种配置参数，但是如果两种配置参数所指示的参考信号时频位置重叠的话，也需要舍弃优先级低的参考信号。
如果s1和s2是不同类型的参考信号，比如s1是波束参考信号，而s2是信道测量参考信号，如果高层配置的两种参考信号时频位置有重叠，还是需要按照优先级顺序只发送优先级高的参考信号而舍弃优先级低的参考信号。
需要说明的是，本实施例不止适用于两个参考信号发送冲突。
预定义的参考信号排序方法可以是按照DCI触发所在的子帧先后来排序，比如DCI后触发的参考信号优先级高，如图9所示，由于s2对应的DCI触发在子帧n2，而子帧n2靠后，所以s2优先级高。所以，基站在子帧n2+m2或者n1+m1时刻只发送测量参考信号s2。按照这种方法的排序可以不考虑参考信号的类型，完全按照DCI所在的子帧、时隙或短时隙等时间单元时间顺序来排列优先级。
可选择的，用户设备不希望基站触发的参考信号在同一个时间单元上发送或者接收。比如，对于上述的下行信道测量参考信号以及波束参考信号，如果s1和s2的资源位置有重叠时，用户设备不希望n2+m2＝n1+m1。
参考信号的资源位置有重叠，指的是在同一个发送时间单元，参考信号所在的时域符号以及频域资源位置全部重叠或者部分重叠，如图9。
可选择的，预定义的参考信号排序方法可以是按照s1和s2的密度，或者带宽长度，或者端口数多少进行优先级排序。比如s1信号如果带宽长度大于s2，那么s1的优先级就高，如果它们的时频位置有重叠时，实际s2的触发就失效了。也就是说实际在子帧n2+m2时刻没有s2信号发送。
对于多种类型的测量参考信号触发，以及每种测量参考信号多次触发重叠的优先级排序方法，可选择的，如果s1和s2是不同类型的参考信号，可先按照信号s1和s2的类型进行优先级排序，再按照n1和n2的先后进行优先级排序。比如波束参考信号的优先级高于信道测量参考信号的优先级，如果s1是波束测量参考信号，而s2是CSI-RS，那么即使n2靠后，s1的优先级仍然高于s2。可选择的，如果s1和s2是不同类型的参考信号，先按照信号s1和s2的密度，或者带宽长度，或者端口数多少，或者对应的n1和n2的先后进行优先级排序。再按照信号s1和s2的类型进行优先级排序。
对于优先级排序的规则，可以每个用户设备不同，这时需要基站通过高层信令来配置给每个用户设备。比如用户设备1是按照DCI触发时刻先后来排序的，且不分参考信号种类。而用户设备2是波束参考信号优先级高，而CSI-RS优先级低，且先按照参考信号种类排序再按照DCI触发时刻先后顺序排序。
对于不同的传输区域，图10是本实施例的不用传输区域的复用示意图，比如图10，两个传输区域频域复用在系统带宽上，传输区域1和传输区域2的子载波间隔不同，所以每个时域OFDM符号长度也不同，而导致子帧长度不同。这样基站可通过高层信令来单独配置两个传输区域的优先级规则。
m1，m2的候选值是通过高层信令配置的，且对于不同用户设备m的候选值可以不同。m表示在DCI触发时刻m个子帧后发送测量参考信号。例如对于用户设备1，m的候选值是0，1，2，3.而对于用户设备2，m的值是0，1。由于不同用户设备处理能力不同，所需要的处理时延不同，所以m的候选值不同可以带来灵活性。另外，对于时延要求高的用户设备，m的候选值可以配置小些，而对时延要求低的用户设备，m的候选值可以 多配置一些以增加灵活性。当然即使对于同一个用户设备，对于不同的传输区域，基站的通过高层信令单独配置不同的m候选值。值得注意的是，灵活的m候选值得这种方法可以不受限于参考信号排序方法。也就是说，即使系统不对这些参考信号进行排序，灵活的m候选值方案也可以给系统带来好处。
信号s1和信号s2包括信道测量参考信号测量结果的反馈，波束参考信号测量结果的反馈，预编码信道测量参考信号测量结果的反馈等。这些测量结果的反馈可以在上行数据信道上传输，也可以在上行控制信道上传输，所对应的资源位置重叠或者冲突分别就是上行数据信道的冲突和上行控制信道的冲突。
基站在子帧n时刻触发了测量参考信号后，并且通知用户设备在子帧n+m时刻会发送测量参考信号，那么在子帧n+m+k时刻用户设备会将测量结果反馈给基站。而k的值一般也是基站在子帧n时刻通过DCI告诉用户设备的。所以对于反馈信号s，基站也需要在DCI中触发，而信号s发送的时刻为n+m+k。
k的候选值可以是高层信令配置的，类似于m，不同用户设备k的候选值可以不同，例如基站通过高层信令通知用户设备1k的候选值是0，1…7，而用户设备2的候选值是0，1，…3。当然即使对于同一个用户设备，不同传输区域可以用高层信令单独配置不同的k的候选值。
图11是实施例的信号s1在子帧n1+m1上的参考信号的测量反馈示意图，如图11所示，信号s1表示对于在子帧n1+m1上参考信号的测量反馈，即基站在子帧n1的控制区域上触发反馈信号s1，而s1是对在子帧n1+m1上的参考信号的测量结果的反馈，由用户设备在子帧n1+m1+k1发送，基站接收。而s2表示用户设备对于在子帧n2+m2上发送的参考信号的测量反馈。即基站在子帧n2的控制区域上触发反馈信号s2，而s2是对在子帧 n2+m2上的参考信号的测量结果的反馈，由用户设备在子帧n2+m2+k2发送，基站接收。如果n1+m1+k1＝n2+m2+k2，且反馈的资源有重叠时，可能需要合并或者优先级排序。
这些测量结果的反馈可能利用上行数据信道反馈，也可能利用上行控制信道进行反馈。资源重叠可能仅仅是时间单元重叠，而频域位置不重叠也行，比如对于上行数据信道的重叠可以指的是仅时间单元相同。也就是说，资源位置的重叠或者冲突可能是时域，频域，码域中的一个或者多个有重叠。
如果用户设备是在物理层数据信道上反馈测量结果，那么即使s1和s2的时频资源在一个子帧，用户设备可同时将s1和s2都反馈给基站。此时基站会在同一个子帧收到s1和s2。当然，也可以按照优先级顺序只反馈优先级高的测量结果。
如果用户设备是在物理层上行控制信道反馈测量结果，而s1和s2所用的控制信道资源位置重叠或者完全冲突，那么需要按照优先级顺序只反馈优先级高的测量结果。
优先级的顺序同样可以按照所触发的DCI所在的子帧、时隙、短时隙的时间顺序排序。比如图11所示，信号s2的优先级高于s1因为n2相对于n1靠后。
当然，也可也按照s1和s2所对应的参考信号发送的子帧顺序来决定优先级。也就是说根据子帧n1+m1和n2+m2的顺序来决定优先级。比如靠后的RS对应的反馈信号优先级高。
可选择的，类似于参考信号的优先级排序，测量结果反馈信号的优先级也可以按照对应的参考信号的类型，密度，带宽长度，端口数多少等决定优先级顺序。比如，对于上行信道控制的反馈，如果波束参考信号对应测量结果的发送资源与信道测量参考信号测量结果的资源有冲突，那么 可以定义波束测量参考信号的测量结果优先级高。那么用户设备在发送时就会舍弃优先级低的信道测量结果的反馈。
类似的，如果信号s1和s2是上行数据信道，那么用户设备可以根据n1和n2的先后顺序来判断优先级。用户设备可在相应的子帧只发送优先级高的上行数据。
对于上行数据的发送，可选择的，用户设备不希望接收到多次触发，而这多次触发的是同一个上行子帧的上行数据发送。类似的，对于测量结果的反馈，可选择的，用户设备不希望接收到多次触发，而这多次触发的是同一个上行子帧的测量结果反馈。尤其是对于同一种参考信号的测量结果反馈。比如，对于信道测量结果反馈，用户设备不希望接收到在同一个上行子帧反馈的多次触发(这多次触发的DCI可以在不同子帧)，也即是说，用户设备不希望n1+m1＝n2+m2。类似的，对于参考信号的发送或者接收，用户设备不希望接收到多次触发，而这多次触发的是在同一个子帧上且资源位置有重叠的参考信号的发送或者接收。此时，也就不需要优先级排序，可以依赖基站的实现来避免s1和s2的资源位置冲突。
如果信号s1和s2包括以下一个或多个信号时，按照信号s1和s2包含的内容进行优先级排序：上行调度的数据，信道测量参考信号对应的测量结果反馈，波束参考信号对应的测量结果反馈，预编码测量参考信号对应的测量结果反馈，下行调度对应的ACK/NACK反馈。比如，上行数据的优先级可以根据包含的内容来区分。比如，上行数据信号s1包含了CSI反馈，而s2没有包含，那么可以不考虑n1和n2的先后，可以判断s1的优先级高。也就是说包含CSI反馈的上行数据发送优先级高。
如果信号s1和s2包括以下一个或多个信号时，同时接收s1和s2的全部或
者部分信息：上行调度的数据，信道测量参考信号对应的测量结果反 馈，波束参考信号对应的测量结果反馈，预编码测量参考信号对应的测量结果反馈，下行调度对应的ACK/NACK反馈。例如，在上行数据信道上发送时，即使n1+m1＝n2+m2，用户设备也可同时发送这些信号。
可选地，下面以具体实施例具体说明本本实施例的方法：
上行数据的触发调度。
图12是本实施例的基站在子帧#n1中用DCI动态触发上行数据的发送示意图，如图12所示，基站在子帧#n1中用DCI动态触发上行数据的发送，用户设备在子帧#n1中检测到该DCI后会在子帧#n1+m1发送上行数据s1。具体m1的值可在DCI中检测得到。而同时，用户设备又在子帧#n2的DCI检测到上行数据s2的调度，且发送数据的时刻也是#n1+m1，即n1+m1＝n2+m2。即s1和s2的资源位置有重叠。由于一个用户设备可能不支持在同一个时刻发送两次独立调度的上行数据，所以只要时域单元重叠就满足本发明所说的资源位置重叠。
根据本发明的优先级排序方法，可以根据n1和n2的大小进行排序，即DCI所在的时域单元靠后的上行数据发送优先级高。所以用户设备在子帧#n1+m1时刻只会发送上行数据s2。
可选的，可以根据s1和s2所包含的内容来判断优先级。比如，如果基站在子帧#n1时刻触发的上行数据时，同时触发了参考信号测量结果的反馈，并且调度用户设备在子帧#n1+m1时刻发送，而后来在子帧#n2中调度的上行数据时没有触发测量结果上报，那么s1的优先级高于s2。
可选择的，基站可同时接收s1和s2的全部或者部分信息。如图12所示，如果基站在子帧#n1和子帧#n2上调度的上行数据中都包含了某参考信号的测量结果反馈。那么此时可先根据内容进行优先级排序，即子帧#n1和子帧#n2上触发的测量结果反馈的优先级高于数据发送，其次再根据n1，n2的大小进行排序，即子帧#n2上触发调度的上行数据内容优先级高于子 帧#n1上触发调度的上行数据内容，所以最终，用户设备可在子帧#n2的上行数据区域发送子帧#n1和子帧#n2上触发的测量结果的反馈和在子帧#n2上触发的上行数据。所以在优先级排序上，可以先根据信号包含的内容进行排序，例如是否包含信道测量结果反馈，然后再根据DCI触发所在的子帧先后来排序。
可选择的，用户设备不希望收到多个DCI触发的在同一个子帧的上行数据调度。
