具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或 先后次序。
本发明实施例的构思在于，通过获取基站覆盖范围内各终端的信道质量，可以这些终端中选择出满足SRS分配条件的终端，也就是信道条件更好的那部分终端，作为目标终端，然后对目标终端进行SRS分配，这样可以避免将SRS时频资源分配到信道质量差的终端上，使SRS时频资源不产生浪费。下面通过具体实施方式结合附图对本发明实施例作进一步详细说明。
实施例一
本实施例提供了一种信道探测参考信号动态调度方法，请参考图1，包括：
S11，获取基站覆盖范围内各终端的信道质量；
S12，根据各终端的信道质量选择出满足信道探测参考信号调度条件的终端作为目标终端；
S13，对目标终端进行信道探测参考信号调度。
基站覆盖范围内各终端的信道，指的是基站与终端之间的信道，这个信道包括了上行信道和下行信道，其中上行信道是终端发送业务到基站的信道，下行信道是基站发送业务到终端的信道。在LTE(Long Term Evolution，长期演进)系统中，信道的模式分为TDD(Time Division Duplexing，时分双工)模式和FDD(Frequency Division Duplexing，频分双工)模式，其中TDD模式采用的是在相同的频段不同的时隙上实现上下行的业务传输，FDD是采用成对的频段实现上下行的业务传输。
获取终端的信道质量包括获取终端的上行信道的质量。上行信道包括PUCCH(Physical Uplink Control CHannel，物理上行链路控制信道)和PUSCH(Physical Uplink Shared CHannel，物理上行共享信道)，其中，PUCCH是一直存在的，而PUSCH是终端有上行业务的前提下才会存在的。为了获取上行信道的质量，本实施例采用以下方案：
方案一：获取终端的PUCCH的SINR值(Signal to Interference plus Noise Ratio，信噪比)。由于PUCCH对终端而言是一直存在的，这个SINR值在正常情况下各终端都可以获取到；SINR值是信号与干扰加噪声的比，那么这个值越大，说明PUCCH受到的干扰以及噪声越小，信道质量当然也就越好。在本实施例中，当终端的PUCCH的SINR值大于等于第一门限值，那么该终端即满足本实施例中的SRS调度条件，即该终端为目标终端。其中，第一门限值为一个预设的PUCCH的SINR值的阈值，其并不是固定值，可以根据具体的SRS时频资源的调度能力以及基站覆盖范围内终端的数量以及其他条件确定。而那些PUCCH的SINR值小于第一门限值的，原则上不作为目标终端，当然，在选择出的目标终端数量过少的时候，可以将其作为目标终端，这也在另一种程度上说明了第一门限值是可变的。
在某些情况下，用上述方法确定出的目标终端的数量，可能会超过期望的数量K，这个K是小于等于SRS时频资源调度的总数T的；为了解决这个问题，SRS调度条件还可以包括当PUCCH的SINR值大于等于第一门限值的终端数L1大于等于K时，从这L1个终端中选择K个作为目标终端。这里的选择方案可以是在这L1中随机选择K个，也可以将这L1个终端进行排序，然后依次选取。当然，优选的方案是选择这L1个终端中PUCCH的SINR值较大的终端，也就是在这L1个终端中以SINR值从大到小选择K个作为目标终端，这K个目标终端的信道质量是最好的。
方案二：首先获取终端的PUSCH的SINR值，如果没有获取到终端的PUSCH的SINR值，即终端没有上行业务，此时再获取终端的PUCCH的SINR值。与PUCCH不同，PUSCH的SINR值对终端的信道质量的反馈更加的准确，在这种情况下，如果终端的PUSCH的SINR值大于等于第二门限值，说明该终端的信道质量满足SRS调度条件，则将该终端作为目标终端。没有获取到PUSCH的SINR值的那部分终端，若获取到的PUCCH的SINR值大于等于第一门限值，则说明该终端的信道质量也满足SRS调度条件，也将该终端作为目标终端。其中，第二门限值是一个预 设的PUSCH的SINR值的阈值，其并不是固定值，可以根据具体的SRS时频资源的调度能力以及基站覆盖范围内终端的数量以及其他条件确定。而且，这里的第二门限值和第一门限值可以取同样的值。采用终端的PUSCH的SINR值作为评判终端的上行信道的信道质量的参考指标是因为PUSCH的SINR值比以PUCCH的SINR值作为参考指标来的更为精确，事实上，由于终端不会每时每刻都有上行业务，所以终端的PUSCH不会一直存在，在有PUSCH存在的前提下，本实施例优先获取终端的PUSCH的SINR值，而在不存在PUSCH的前提下，再对终端的PUCCH的SINR值进行获取。
在某些情况下，用上述方法确定出的目标终端的数量，可能超过了预期的目标终端数K，这个K是小于等于SRS时频资源调度的总数T的；为了解决这个问题，本实施例的SRS的调度条件还可以包括：若PUSCH的SINR值大于等于第二门限值的终端数为M1，PUCCH的SINR值大于等于第一门限值的终端数为L2，而M1与L2之和大于等于K，则从这M1+L2个中选择K个作为目标终端。这里的选择方案，可以是从这M1+L2个中随机选择K个作为目标终端，也可以时按照一定的规则，如以更准确的PUSCH的SINR值为主，或者是均匀的从两者中选择出SINR值较高的，这些方案都是可行的。
由于LTE系统分为了TDD模式和FDD模式，在TDD模式下的终端的上行信道和下行信道采用的是同一频段，也就是说上行信道可以很好的由下行信道的质量来反映，FDD模式采用的非同一频段的模式来完成，其下行信道并不能很好的反应上行信道的质量，也就是说，在终端与基站之间的信道为TDD模式时，在方案一中，可以在获取PUCCH的SINR值之前，对终端的下行信道的CSI值(Channel State Information，信道状态信息)进行获取；由于终端的CSI值是由终端反馈上报的，如果终端没有上报CSI值，即获取失败，此时再对终端的PUCCH的SINR值进行获取。如果终端的下行信道的CSI值大于等于第三门限值，即说明该终端的信道质量满足SRS调度条件，则将该终端作为目标终端。没有获取到下行信道 的CSI值的那部分终端，若获取到的PUCCH的SINR值大于等于第一门限值，则说明该终端的信道质量也满足SRS调度条件，也将该终端作为目标终端。其中，第三门限值是一个预设的下行信道的CSI的阈值，其并不是固定值，可以根据具体的SRS时频资源的调度能力以及基站覆盖范围内终端的数量以及其他条件确定。在TDD模式下，终端的上下行信道都在同一个频段，其上下行的信道质量有很大的参考价值，这样的前提下，若是能获取到终端的下行信道的CSI值，则可以用该CSI值作为评判标准；若是没能获取到CSI值，就以一定存在的PUCCH的SINR值作为评判标准，这是基于准确度的考虑。
在某些情况下，用上述方法确定出的目标终端的数量可能会超过了预期的数量K，这个K是小于等于SRS时频资源调度的总数T的；为了解决这个问题，本实施例中的SRS调度条件还可以包括：若CSI大于等于第三门限值的终端的数量为N1，PUCCH的SINR值大于等于第一门限值的终端的数量为L3，N1与L3之和大于等于K，则从这N1+L3个终端中选择K个作为目标终端。这里的选择方案，可以是从这N1+L3个中随机选择K个作为目标终端，也可以时按照一定的规则，如以更准确的CSI值为主，或者是均匀的从两者中选择，这些方案都是可行的。
同样的，在TDD模式下，当采用方案二来获取终端的信道质量时，可以在获取终端的PUSCH的SINR值失败之后，获取终端的PUCCH的SINR值之前，获取终端的下行信道的CSI值，若获取失败，再对终端的PUCCH的SINR值进行获取。如果终端的下行信道的CSI值大于等于第三门限值，即说明该终端的信道质量满足SRS调度条件，则将该终端作为目标终端。在本方案中，由于是首先获取终端的PUSCH的SINR值，获取失败再获取上行信道的CSI值，若还是获取失败才获取PUCCH的SINR值，那么在本方案中，若获取到的终端的PUSCH的SINR值大于等于第二门限值，没有获取到PUSCH的SINR值而获取到下行信道的CSI值的终端的CSI值大于等于第三门限值，以及获取PUSCH的SINR值和获取下行信道的CSI值均失败而获取到PUCCH的SINR值的终端的PUCCH 的SINR值大于等于第一门限值，则说明这些终端的信道条件均满足SRS调度条件，将这些终端作为目标终端。用存在的上行业务的上行信道的信噪比来衡量终端的上行信道的质量当然是最准确的，故此处以终端的PUSCH的SINR值作为标准是更理想的，但由于终端的上行业务并不是一直都会有，而在TDD模式下，终端的下行信道与上行信道同处在一个频段内，其下行信道的信道质量对上行信道有很高的参考价值，在获取不到终端的PUSCH的SINR值的前提下，获取终端的下行信道的CSI值也是一个不错的选择；当然，若是终端没有CSI的上报，此时只能获取终端的PUCCH的SINR值，来评判终端的上行信道的信道质量如何。
在某些情况下，用上述方法确定出的目标终端的数量可能会超过了预期的数量K，这个K是小于等于SRS时频资源调度的总数T的；为了解决这个问题，本实施例中的SRS调度条件还可以包括：若PUCCH的SINR值大于等于第二门限值的终端数量为M2，下行信道的CSI值大于等于第三门限值的终端数量为N2，PUCCH的SINR值大于等于第一门限值的终端数量为L4，M2与N2以及L4之和大于等于K，则从这M2+N2+L4个终端中选择K个作为目标终端。这里的选择方案，可以是随机选择K个作为目标终端，可可以按照一定的规则，或是均匀的从三者中选择，这些方案都是可行的。
此外，终端与基站之间的信道为FDD模式时，虽然其上下行信道并不在一个频段，在某种程度上，其下行信道的质量也可以作为上行信道的参考。
上述的各个方案之间，可以参考多个方案一起执行，以期确定出信道质量最好的那部分终端，达到最好的SRS时频资源调度效果。
实施例二
本实施例提供了一种基站，请参考图2：
本实施例中的基站包括信道探测参考信号动态调度装置20，其中SRS 动态调度装置20包括获取单元21，选择单元22，调度单元23；
获取单元21设置为获取基站覆盖范围内各个终端的信道质量，选择单元22设置为根据各终端的信道质量选择出满足SRS调度条件的终端作为目标终端，调度单元23设置为对目标终端进行SRS调度。
当基站与终端之间的信道为TDD或FDD模式时，此时可以获取终端的上行信道的信道质量作为终端信道质量的评判标准。获取单元21包括第一获取模块211，第一获取模块211设置为获取终端的上行信道的信道质量。第一获取模块211包括第一获取子模块2111或第二获取子模块2112；其中，第一获取子模块2111设置为执行方案一，获取终端的PUCCH的SINR值；而第二获取子模块2112设置为执行方案二，先获取终端的PUSCH的SINR值，若获取失败，则说明该终端没有上行业务，此时再获取终端的PUCCH的SINR值。
在方案一中，SRS调度条件包括将获取到的终端的PUCCH的SINR值与第一门限值进行比较，若该终端的PUCCH的SINR值大于等于第一门限值，则选择单元22将该终端作为目标终端，然后由调度单元23对目标终端进行SRS调度。而在这样的SRS调度条件下选择出的目标终端，其总数可能大于K，则SRS调度条件还可以包括：当PUCCH的SINR值大于等于第一门限值的终端数L1大于等于K时，从这L1个终端中选择K个作为目标终端。
在方案二中，由于先获取终端的PUSCH的SINR值，若获取失败再获取终端的PUCCH的SINR值，说明获取到的终端的上行信道的信道质量一部分为PUSCH的SINR值，另一部分为PUCCH的SINR值，在这样的情况下，SRS调度条件包括获取到PUSCH的SINR值的终端，其PUSCH的SINR值大于等于第二门限值，且获取到PUCCH的SINR值的终端，其PUCCH的SINR值大于等于第一门限值，则选择单元22将这些终端均作为目标终端。而在这样的SRS调度条件下选择出的目标终端，其总数可能大于K，则SRS调度条件还可以包括若PUSCH的SINR值大 于等于第二门限值的终端数为M1，PUCCH的SINR值大于等于第一门限值的终端数为L2，而M1与L2之和大于等于K，则从这M1+L2个中选择K个作为目标终端。
此外，获取单元21还包括第二获取模块212，设置为当基站和终端之间的信道为TDD模式时，获取终端的下行信道的信道质量；第二获取模块212包括第三获取子模块2121或第四获取子模块2122。
第三获取子模块2121设置为当第一获取模块211包括第一获取子模块2111时，即采用方案一时，在第一获取子模块2111获取终端的PUCCH的SINR值之前，获取终端的下行信道的CSI值，如果获取失败，再由第一获取子模块2111获取PUCCH的SINR值。此时，由于先获取终端的下行信道的CSI值，若获取失败，再获取终端的PUCCH的SINR值，说明获取到的终端的信道质量一部分为终端的下行信道的CSI值，另一部分为终端的PUCCH的SINR值，则SRS调度条件包括：获取到下行信道的CSI的终端，其下行信道的CSI大于等于第三门限值，且获取到PUCCH的SINR值的终端，其PUCCH的SINR值大于等于第一门限值，则选择单元22将这些终端均作为目标终端，再由调度单元23对目标终端进行SRS调度。而在这样的SRS调度条件下选择出的目标终端，其总数可能大于K，则SRS调度条件还可以包括：若CSI大于等于第三门限值的终端的数量为N1，PUCCH的SINR值大于等于第一门限值的终端的数量为L3，N1与L3之和大于等于K，则从这N1+L3个终端中选择K个作为目标终端。
第四获取子模块2122设置为当第一获取模块211包括第二获取子模块2112时，即采用方案二时，在第二获取子模块2112获取终端的PUSCH的SINR值失败之后，且在第二获取子模块2112获取终端的PUCCH的SINR值之前，获取终端的下行信道的CSI值；若获取失败，说明终端没有CSI值的上报，此时再由第二获取子模块2112获取终端的PUCCH的SINR值。由于先获取终端的PUSCH的SINR值，获取失败再获取终端的下行信道的CSI值，若还是获取失败，再获取终端的PUCCH的SINR值， 说明获取到的终端的信道质量，一部分为终端的PUSCH的SINR值，一部分为终端的下行信道的CSI值，还有一部分为终端的PUCCH的SINR值，则SRS调度条件包括：获取到PUSCH的SINR值的终端，其PUSCH的SINR值大于等于第二门限值，且获取到下行信道的CSI值的终端，其下行信道的CSI值大于等于第三门限值，以及获取到PUCCH的SINR值的终端，其PUCCH的SINR值大于等于第一门限值，则选择单元22将这些终端均作为目标终端，再由调度单元23对目标终端进行SRS调度。而在这样的SRS调度条件下选择出的目标终端，其总数可能大于K，则SRS调度条件还可以包括：若PUCCH的SINR值大于等于第二门限值的终端数量为M2，下行信道的CSI值大于等于第三门限值的终端数量为N2，PUCCH的SINR值大于等于第一门限值的终端数量为L4，M2与N2以及L4之和大于等于K，则从这M2+N2+L4个终端中选择K个作为目标终端。
获取单元21在本实施例中一般直接采用基站原有的获取终端的信道质量的物理实体来实现，包括终端的PUCCH的SINR值、终端的PUSCH的SINR值以及终端的下行信道的CSI值等；当然，也可以采用其他装置来实现对终端的信道质量的获取，任何能直接或间接获取终端的信道质量的装置在本实施例中都是适用的。
实施例三
本实施例提供了一种SRS动态调度方法，请参考图3：
当终端与基站之间的信道为TDD模式时，其SRS动态调度方法可以包括：
S41，判断基站覆盖区域内的终端数量是否大于预设的总数K。如果基站覆盖区域内终端的总数不大于K，则调度单元23直接对这些终端进行SRS调度。
S42，若基站覆盖区域内终端的总数大于K，则，第二获取子模块2112 获取各终端的PUSCH的SINR值。
S421，第二获取子模块2112获取到终端的PUSCH的SINR值之后，判断其是否大于第二门限值，若是，则将这些终端作为准目标终端；这里指的准目标终端，是指在一般情况下，这些终端会作为待调度的目标终端，只要最后所有的准目标终端的总数不大于K。
S43，若获取终端的PUSCH的SINR值失败，则第四获取子模块2122获取终端的下行信道的CSI值。
S431，获取到终端的下行信道的CSI值之后，判断其是否大于第三门限值，若是，则将这些终端作为准目标终端。
S44，若获取终端的下行信道的CSI值仍然失败，则第二获取子模块2112获取终端的PUCCH的SINR值。
S441，获取到终端的PUCCH的SINR值后，判断其是否大于第一门限值，若是，则将这些终端作为准目标终端。
S45，判断步骤S421、S431、S441中获取到的准目标终端的总数是否大于K。若准目标终端的总数不大于K，则选择单元22将这些准目标终端作为目标终端，并由调度单元23进行SRS调度。
S46，若步骤S421、S431、S441中获取到的准目标终端的总数大于K，则选择单元22从这些准目标终端中选出K个作为目标终端。
S47，调度单元23对目标终端进行SRS调度。
实施例四
本实施例提供了一种SRS动态调度方法，请参考图4：
在基站与终端之间的信道为TDD或FDD模式时，SRS动态调度方法可以包括：
S51，判断基站覆盖区域内的终端数量是否大于预设的总数K。如果基站覆盖区域内终端的总数不大于K，则调度单元23直接对这些终端进 行SRS调度。
S52，若基站覆盖区域内终端的总数大于K，则，第一获取子模块2111获取各终端的PUCCH的SINR值。
S53，第一获取子模块2111获取到终端的PUCCH的SINR值之后，判断其是否大于第二门限值，若是，则将这些终端作为准目标终端。获取终端的PUCCH的SINR值是考虑到终端的PUCCH是常在的，获取PUCCH的SINR值具有普遍性，容易实现。
S54，判断步骤S53中获取到的准目标终端的总数是否大于K。若准目标终端的总数不大于K，则选择单元22将这些准目标终端作为目标终端，并由调度单元23进行SRS调度。
S55，若步骤S53中获取到的准目标终端的总数大于K，则选择单元22从这些准目标终端中选出K个作为目标终端。
S56，调度单元23对目标终端进行SRS调度。
实施例五
本实施例提供了一种SRS动态调度方法，请参考图5：
在基站与终端之间的信道为TDD或FDD模式时，SRS动态调度方法可以包括：
S61，判断基站覆盖区域内的终端数量是否大于预设的总数K。若果基站覆盖区域内终端的总数不大于K，则调度单元23直接对这些终端进行SRS调度。
S62，若基站覆盖区域内终端的总数大于K，则，第二获取子模块2112获取各终端的PUSCH的SINR值。获取终端的PUSCH的SINR值是在终端存在上行业务的前提下才能获取到，另一个方面来说，以终端的PUSCH的SINR值作为参考比PUCCH的SINR值更为准确，在可能的情况下尽量获取终端的PUSCH的SINR值。
S63，第二获取子模块2112获取到终端的PUSCH的SINR值之后，判断其是否大于第二门限值，若是，则将这些终端作为准目标终端。
S64，判断步骤S63中获取到的准目标终端的总数是否大于K。若准目标终端的总数不大于K，则选择单元22将这些准目标终端作为目标终端，并由调度单元23进行SRS调度。
S65，若步骤S63中获取到的准目标终端的总数大于K，则选择单元22从这些准目标终端中选出K个作为目标终端。
S66，调度单元23对目标终端进行SRS调度。
实施例六
本实施例提供了一种SRS动态调度方法，请参考图6：
在基站与终端之间的信道为TDD模式时，SRS动态调度方法可以包括：
S71，判断基站覆盖区域内的终端数量是否大于预设的总数K。若果基站覆盖区域内终端的总数不大于K，则调度单元23直接对这些终端进行SRS调度。
S72，若基站覆盖区域内终端的总数大于K，则，第三获取子模块2121或第四获取子模块2122获取各终端的下行信道的CSI值。在终端存在下行信道的CSI上报的前提下，获取该CSI值也是一个不错的选择，在TDD模式下，终端的上行信道的信道质量可以很好的由下行信道的信道质量来反映。
S73，第三获取子模块2121或第四获取子模块2122获取到终端的下行信道的CSI值之后，判断其是否大于第三门限值，若是，则将这些终端作为准目标终端。
S74，判断步骤S73中获取到的准目标终端的总数是否大于K。若准目标终端的总数不大于K，则选择单元22将这些准目标终端作为目标终端，并由调度单元23进行SRS调度。
S75，若步骤S73中获取到的准目标终端的总数大于K，则选择单元22从这些准目标终端中选出K个作为目标终端。
S76，调度单元23对目标终端进行SRS调度。
